Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Nature of the Business	1. Organization and Nature of the Business Better Home & Finance Holding Company, formerly known as Aurora Acquisition Corp. (“Aurora”), together with its subsidiaries (collectively, the “Company”), provides a comprehensive set of homeownership offerings in the United States while expanding in the United Kingdom. The Company’s offerings include mortgage loans, real estate agent services, title and homeowner’s insurance, and other homeownership offerings, such as the Company’s cash offer program. The Company leverages Tinman, its proprietary technology platform, to optimize the mortgage process from the initial application, to the integration of a suite of additional homeownership offerings, to the sale of loans to a network of loan purchasers. Mortgage loans originated within the United States are through the Company’s wholly-owned subsidiary Better Mortgage Corporation (“BMC”). BMC is an approved Title II Single Family Program Lender with the Department of Housing and Urban Development’s (“HUD”) Federal Housing Administration (“FHA”), and is an approved seller and servicer with the Federal National Mortgage Association (“FNMA”) and the Federal Home Loan Mortgage Corporation (“FMCC”). The Company has expanded into the U.K. and offers a multitude of financial products and services to consumers via regulated entities obtained through acquisitions. On August 22, 2023 (the “Closing Date”), the Company consummated the previously announced Business Combination (the “Business Combination”), pursuant to the terms of the Agreement and Plan of Merger, dated as of May 10, 2021, as amended as of October 27, 2021, November 9, 2021, November 30, 2021, August 26, 2022, February 24, 2023 and June 23, 2023 (as amended, the “Merger Agreement”), by and among Aurora, Better Holdco, Inc. (“Better”), and Aurora Merger Sub I, Inc., formerly a wholly owned subsidiary of Aurora (“Merger Sub”). On the Closing Date, Merger Sub merged with and into Better, with Better surviving the merger (the “First Merger”) and Better merged with and into Aurora, with Aurora surviving the merger and changing its name to “Better Home & Finance Holding Company” (referred to as “Better Home & Finance” or the “Company”) (such merger, the “Second Merger,” and together with the First Merger, the “Business Combination” and the completion thereof, the “Closing”).

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation —The accompanying condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The Business Combination has been accounted for as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, Aurora was treated as the “acquired” company for financial reporting purposes. Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of Better issuing stock for the net assets of Aurora, accompanied by a recapitalization. All share amounts in periods prior to the Business Combination have been retroactively adjusted using the Exchange Ratio for the equivalent number of shares outstanding immediately after the Business Combination to effect the reverse recapitalization. The financials of Better are presented here for all comparative periods. In the opinion of the Company, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting of only normal recurring adjustments, necessary for a fair presentation of its financial position and its results of operations, changes in convertible preferred stock and stockholders’ equity (deficit) and cash flows. The results of operations and other information for the nine months ended September 30, 2023 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2023. The unaudited condensed consolidated financial statements presented herein should be read in conjunction with the audited consolidated financial statements and related notes of Better thereto for the year ended December 31, 2022. Consolidation —The accompanying condensed consolidated financial statements include the accounts of the Company and its consolidated subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates —The preparation of condensed consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the fair value of mortgage loans held for sale, the fair value of derivative assets and liabilities, including bifurcated derivatives, interest rate lock commitments and forward sale commitments, the determination of a valuation allowance on the Company’s deferred tax assets, capitalization of internally developed software and its associated useful life, determination of fair value of the Company’s common stock, stock option and RSUs at grant date, the fair value of acquired intangible assets and goodwill, the provision for loan repurchase reserves, the incremental borrowing rate used in determining lease liabilities and warrant liabilities. Business Combinations —The Company includes the financial results of businesses that the Company acquires from the date of acquisition. The Company records all assets acquired and liabilities assumed at fair value, with the excess of the purchase price over the aggregate fair values recorded as goodwill. Determining the fair value of assets acquired and liabilities assumed requires management to use significant judgment and estimates including the selection of valuation methodologies, estimates of future revenue and cash flows, discount rates and selection of comparable companies. During the measurement period the Company may record adjustments to the assets acquired and liabilities assumed. Transaction costs associated with business combinations are expensed as incurred. Short-term investments —Short term investments consist of fixed income securities, typically U.K. government treasury securities and U.K. government agency securities with maturities ranging from 91 days to one year. Management determines the appropriate classification of short-term investments at the time of purchase. Short-term investments reported as held-to-maturity are those investments which the Company has both the positive intent and ability to hold to maturity and are stated at amortized cost on the condensed consolidated balance sheets. All of the Company’s short term investments are classified as held to maturity. The Company has not recognized any impairments on these investments to date and any unrealized gains or losses on these investments are immaterial. Allowance for Credit Losses - Held to Maturity (“HTM”) Short-term Investments—The Company's HTM Short-term investments are also required to utilize the Current Expected Credit Loss (“CECL”) approach to estimate expected credit losses. Management measures expected credit losses on short-term investments on a collective basis by major security types that share similar risk characteristics, such as financial asset type and collateral type adjusted for current conditions and reasonable and supportable forecasts. Management classifies the short term investments portfolio by security types, such as U.K. government agency. The U.K. government treasury securities and U.K. government agency securities are issued by U.K. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.K. government as to timely repayment of principal and interest, are highly rated by major rating agencies, and have a long history of no credit losses. Therefore, credit losses for these securities were immaterial as the Company does not currently expect any material credit losses. Mortgage Loans Held for Sale, at Fair Value —The Company sells its mortgage loans held for sale (“LHFS”) to loan purchasers. These loans can be sold in one of two ways, servicing released, or servicing retained. If a loan is sold servicing released, the Company has sold all the rights to the loan and the associated servicing rights. If a loan is sold servicing retained, the Company has sold the loan and kept the servicing rights, and thus the Company is responsible for collecting monthly principal and interest payments and performing certain escrow services for the borrower. The loan purchaser, in turn, pays a fee for these services. The Company generally sells all of its loans servicing released. For interim servicing, the Company engages a third-party sub-servicer to collect monthly payments and perform associated services. LHFS consists of loans originated for sale by BMC. The Company elects the fair value option, in accordance with Accounting Standard Codification (“ASC”) 825 – Financial Instruments (“ASC 825”), for all LHFS with changes in fair value recorded in mortgage platform revenue, net in the condensed consolidated statements of operations and comprehensive loss. Management believes that the election of the fair value option for LHFS improves financial reporting by presenting the most relevant market indication of LHFS. The fair value of LHFS is based on market prices and yields at period end. The Company accounts for the gains or losses resulting from sales of mortgage loans based on the guidance of ASC 860-20 – Sales of Financial Assets (“ASC 860”). The Company issues interest rate lock commitments (“IRLC”) to originate mortgage loans and the fair value of the IRLC, adjusted for the probability that a given IRLC will close and fund, is recognized within mortgage platform revenue, net. Subsequent changes in the fair value of the IRLC are measured at each reporting period within mortgage platform revenue, net until the loan is funded. When the loan is funded, the IRLC is derecognized and the LHFS is recognized based on the fair value of the loan. The LHFS is subsequently remeasured at fair value at each reporting period and the changes in fair value are included within mortgage platform revenue, net until the loan is sold on the secondary market. When the loan is sold on the secondary market, the LHFS is derecognized and the gain/(loss) is included within mortgage platform revenue, net based on the cash settlement. LHFS are considered sold when the Company surrenders control over the loans. Control is considered to have been surrendered when the transferred loans have been isolated from the Company, are beyond the reach of the Company and its creditors, and the loan purchaser obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred loans. The Company typically considers the above criteria to have been met upon receipt of sales proceeds from the loan purchaser. Loan Repurchase Reserve —The Company sells LHFS in the secondary market and in connection with those sales, makes customary representations and warranties to the relevant loan purchasers about various characteristics of each loan, such as the origination and underwriting guidelines, including but not limited to the validity of the lien securing the loan, property eligibility, borrower credit, income and asset requirements, and compliance with applicable federal, state and local laws. In the event of a breach of its representations and warranties, the Company may be required to repurchase the loan with the identified defects. The loan repurchase reserve on loans sold relates to expenses incurred due to the potential repurchase of loans, indemnification of losses based on alleged violations or representations and warranties, which are customary to the mortgage banking industry. Provisions for potential losses are charged to expenses and are included within mortgage platform expenses on the consolidated statements of operations and comprehensive loss. The loan repurchase reserve represents the Company’s estimate of the total losses expected to occur and is considered to be adequate by management based upon the Company’s evaluation of the potential exposure related to the loan sale agreements over the life of the associated loans sold. The Company records the loan repurchase reserve within other liabilities on the consolidated balance sheets. Fair Value Measurements —Assets and liabilities recorded at fair value on a recurring basis on the condensed consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Fair value is defined as the exchange price that would be received for an asset or an exit price that would be paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The price used to measure fair value is not adjusted for transaction costs. The principal market is the market in which the Company would sell or transfer the asset with the greatest volume and level of activity for the asset. In determining the principal market for an asset or liability, it is assumed that the Company has access to the market as of the measurement date. If no market for the asset exists, or if the Company does not have access to the principal market, a hypothetical market is used. The authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows: Level 1 —Unadjusted quoted market prices in active markets for identical assets or liabilities; Level 2 —Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the asset or liability. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active; and Level 3 —Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Assets and liabilities measured at fair value on a recurring basis include LHFS, derivative assets and liabilities, including IRLCs and forward sale commitments, MSRs, bifurcated derivatives, convertible preferred stock warrants and warrant liabilities. Common stock warrants are measured at fair value at issuance only and are classified as equity on the condensed consolidated balance sheets. When developing fair value measurements, the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs. However, for certain instruments, the Company must utilize unobservable inputs in determining fair value due to the lack of observable inputs in the market, which requires greater judgment in measuring fair value. In instances where there is limited or no observable market data, fair value measurements for assets and liabilities are based primarily upon the Company’s own estimates, and the measurements reflect information and assumptions that management believes a market participant would use in pricing the asset or liability. Upon the Closing of the Business Combination and issuance of the Post-Closing Convertible Notes, the Loan commitment asset was reclassified as a discount to the Post-Closing Convertible Notes and was amortized as part of interest expense over the term of the note. Warehouse Lines of Credit —Warehouse lines of credit represent the outstanding balance of the Company’s warehouse borrowings collateralized by mortgage loans held for sale or related borrowings collateralized by restricted cash. Generally, warehouse lines of credit are used as interim, short-term financing which bears interest at a fixed margin over an index rate, such as the Secured Oversight Financing Rate (“SOFR”). The outstanding balance of the Company’s warehouse lines of credit will fluctuate based on its lending volume. The advances received under the warehouse lines of credit are based upon a percentage of the fair value or par value of the mortgage loans collateralizing the advance, depending upon the type of mortgage loan. Should the fair value of the pledged mortgage loans decline, the warehouse provider may require the Company to provide additional cash collateral or mortgage loans to maintain the required collateral level under the relevant warehouse line. The Company did not incur any significant issuance costs related to its warehouse lines of credit. Post-Closing Convertible Notes— As part of the Closing of the Business Combination, the Company issued convertible notes. Upon initial issuance, convertible notes are evaluated for redemption and conversion features that could result in embedded derivatives that require bifurcation from the notes. Upon initial issuance, any embedded derivatives are measured at fair value. Convertible notes proceeds are allocated between the carrying value of the notes and the fair value of embedded derivatives on the initial issuance date. Any portion of proceeds allocated to embedded derivatives are treated as reductions in, or discounts to, the carrying value of the convertible notes on the issuance date. Embedded derivatives are adjusted to fair value at each reporting period, with the change in fair value included within the consolidated statements of operations and comprehensive income (loss). See Note 10 for further details on the Company’s Post-Closing Convertible Notes. Corporate Line of Credit, net of discount and debt issuance costs —The Company had a line of credit arrangement with a third-party lender. Debt and other related issuance costs are deferred and amortized through the maturity date of the line of credit as interest and amortization on non-funding debt expense. Any modifications of the line of credit arrangement are analyzed as to whether they are an extinguishment or modification of debt on a lender-by-lender basis, which is determined by whether (1) the lender remains the same, and (2) the change in the debt terms is considered substantial. Gains and losses on debt modifications that are considered extinguishments are recognized in current earnings. Debt modifications that are not considered extinguishments are accounted for prospectively through yield adjustments, based on the revised terms (see Note 10). Warrant Liabilities —The Company assumed publicly-traded warrants (“Public Warrants”) issued in Aurora’s initial public offering, private placement warrants issued by Aurora in connection with its formation and warrants attached to certain private placement units (collectively, the “Private Warrants” and, together with the Public Warrants, the “Warrants”). Each Warrant issued entitles the holder to purchase one share of Better Home & Finance Holding Company Class A common stock at an exercise price of $11.50 per share, subject to certain adjustments, at any time commencing 30 days after the consummation of the Business Combination (which for the avoidance of doubt was September 21, 2023). The Public Warrants are publicly traded and may be exercised on a cashless basis upon the occurrence of certain conditions. The Private Warrants are exercisable on a cashless basis and are not redeemable by the Company so long as they are held by the initial purchasers or their permitted transferees, subject to certain exceptions. If the Private Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Warrants will be redeemable by the Company and exercisable by the holders on the same basis as the Public Warrants. The Company evaluated the Public Warrants and Private Warrants and concluded that both meet the definition of a derivative and will be accounted for at fair value in accordance with ASC Topic 815-40, Derivatives and Hedging – Contracts in Entity’s Own Equity , as the Public Warrants and Private Warrants are not considered indexed to the Company's stock. Income Taxes —Income taxes are calculated in accordance with ASC 740, Accounting for Income Taxes . An estimated annual effective tax rate is applied to year-to-date income (loss). At the end of each interim period, the estimated effective tax rate expected to be applicable for the full year is calculated. This method differs from that described in the Company’s income taxes policy footnote in the audited consolidated financial statements and related notes thereto for the year ended December 31, 2022, which describes the Company’s annual significant income tax accounting policy and related methodology. Revenue Recognition —The Company generates revenue from the following streams: 1) Mortgage platform revenue, net includes revenues generated from the Company's mortgage production process. See Note 4. The components of mortgage platform revenue, net are as follows: 1. Net gain (loss) on sale of loans—This represents the premium or discount the Company receives in excess of the loan principal amount and certain fees charged by loan purchasers upon sale of loans into the secondary market. Net gain (loss) on sale of loans includes unrealized changes in the fair value of LHFS which are recognized on a loan by loan basis as part of current period earnings until the loan is sold on the secondary market. The fair value of LHFS is measured based on observable market data. Also included within net gain (loss) on sale of loans is the day one recognition of the fair value of MSRs and any subsequent changes in the measurement of the fair value of the MSRs for loans sold servicing retained, including any gain or loss on subsequent sales of MSRs. 2. Integrated relationship revenue (loss)—Includes fees that the Company receives for originating loans on behalf of an integrated relationship partner which are recognized as revenue (loss) upon the integrated relationship partner’s funding of the loan. Some of the loans originated on behalf of the integrated relationship partner are purchased by the Company. Subsequent changes in fair value of loans purchased by the Company are included as part of current period earnings. These loans may be sold in the secondary market at the Company’s discretion for which any gain on sale is included in this account. For loans sold on the secondary market, the integrated relationship partner will receive a portion of the execution proceeds. A portion of the execution proceeds that is to be allocated to the integrated relationship partner is accrued as a reduction of integrated relationship revenue (loss) when the loan is initially purchased from the integrated relationship partner. 3. Changes in fair value of IRLCs and forward sale commitments—IRLCs include the fair value upon issuance with subsequent changes in the fair value recorded in each reporting period until the loan is sold on the secondary market. Fair value of forward sale commitments hedging IRLC and LHFS are measured based on quoted prices for similar assets. 2) Cash offer program revenue—The Company’s product offering includes a cash offer program (“Better Cash Offer”) where the Company works with a Buyer to identify and purchase a home directly from a property Seller. The Company will then subsequently sell the home to the Buyer. The Buyer may lease the home from the Company while the Buyer and Company go through the customary closing process to transfer ownership of the home to the Buyer. Arrangements where the Buyer leases the home from the Company are accounted for under ASC 842 while arrangements where the Buyer does not lease the home are accounted for under ASC 606. The Buyer does not directly or indirectly contract with the Seller. For arrangements under the Better Cash Offer program that do not involve a lease, upon closing on the sale of the home from the Seller to the Company, the Company holds legal title of the home. The Company is responsible for any obligations related to the home while it holds title and is the legal owner and such is considered the principal in the transaction. The Company holds in inventory any homes where the Buyer does not subsequently purchase from the Company as well as homes held while the Company is waiting to transfer the home to the Buyer. Inventory of homes are included within prepaid expenses and other assets on the condensed consolidated balance sheets. The Company recognizes revenue at the time of the closing of the home sale when title to and possession of the home are transferred to the Buyer. The amount of revenue recognized for each home sale is equal to the full sales price of the home. The contracts with the Buyers contain a single performance obligation that is satisfied upon the closing of the transaction and is typically completed in 1 to 90 days. The Company does not offer warranties for sold homes, and there are no continuing performance obligations following the transaction close date. Also included in Better Cash Offer program revenue is revenue from transactions where the Company purchases the home from the Seller and subsequently leases the home to the Buyer until the title is transferred to the Buyer which is accounted for under ASC 842 in line with the Company’s accounting policy on sales-type leases as described above. 3) Other platform revenue consists of revenue from the Company’s additional homeownership offerings which primarily consist of title insurance, settlement services, and other homeownership offerings. Title insurance, settlement services, and other homeownership offerings—Revenue from title insurance, settlement services, and other homeownership offerings is recognized based on ASU 2014-09, Revenue from Contracts with Customers (“ASC 606”). ASC 606 outlines a single comprehensive model in accounting for revenue arising from contracts with customers. The core principle, involving a five-step process, of the revenue model is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company offers title insurance as an agent and works with third-party providers that underwrite the title insurance policies. For title insurance, the Company recognizes revenue from fees upon the completion of the performance obligation which is when the mortgage transaction closes. For title insurance, the Company is the agent in the transactions as the Company does not control the ability to direct the fulfillment of the service, is not primarily responsible for fulfilling the performance of the service, and does not assume the risk in a claim against a policy. Settlement services revenue includes fees charged for services such as title search fees, wire fees, policy and document preparation, and other mortgage settlement services. The Company recognizes revenues from settlement services upon completion of the performance obligation which is when the mortgage transaction closes. The Company may use a third-party to fulfill these services, but the Company is considered the principal in the transaction as it directs the fulfillment of the services and ultimately bears the risk of nonperformance. As the Company is the principal, revenues from settlement services are presented on a gross basis. Performance obligations for title insurance and settlement services are typically completed 40 to 60 days after the commencement of the loan origination process. Payment for these services is typically settled in cash as part of closing costs to the borrower upon closing of the mortgage transaction. Other homeownership offerings consists primarily of real estate services. For real estate services, the Company generates revenues from fees related to real estate agent services, including cooperative brokerage fees from the Company’s network of third-party real estate agents, as well as brokerage fees earned when the Company provides it’s in-house real estate agents to assist customers in the purchase or sale of a home. The Company recognizes revenues from real estate services upon completion of the performance obligation which is when the mortgage transaction closes. Performance obligations for real estate services are typically completed 40 to 60 days after the commencement of the home search process. Payment for these services is typically settled in cash as part of closing costs to the borrower upon closing of the mortgage transaction. 4) Net interest income (expense)—Includes interest income from LHFS calculated based on the note rate of the respective loan as well as interest expense on warehouse lines of credit. Mortgage Platform Expenses —Mortgage platform expenses consist primarily of origination expenses, appraisal fees, processing expenses, underwriting, closing fees, servicing costs, and sales and operations personnel related expenses. Sales and operations personnel related expenses include compensation and related benefits, stock-based compensation, and allocated occupancy expenses and related overhead based on headcount. These expenses are expensed as incurred with the exception of stock-based compensation, which is recognized over the requisite service period. Cash Offer Program Expenses —Better Cash Offer program expenses include the full cost of the home, including transaction closing costs and costs for maintaining the home before the legal title of the home is transferred to the Buyer. Better Cash Offer program expenses are recognized when title is transferred to the Buyer for arrangements recognized under ASC 606 and when the lease commences for arrangements recognized under ASC 842. Other Platform Expenses —Other platform expenses relate to other non-mortgage homeownership activities, including settlement service expenses, lead generation, and personnel related costs. Settlement service expenses consist of fees for transactional services performed by third-party providers for borrowers while lead generation expenses consist of fees for services related to real estate agents. Personnel related expenses include compensation and related benefits, stock-based compensation, and allocated occupancy expenses and related overhead based on headcount. Other platform expenses are expensed as incurred with the exception of stock-based compensation, which is recognized over the requisite service period. General and Administrative Expenses —General and administrative expenses include personnel related expenses, including stock-based compensation and benefits for executive, finance, accounting, legal, and other administrative personnel. In addition, general and administrative expenses include external legal, tax and accounting services, and allocated occupancy expenses and related overhead based on headcount. General and administrative expenses are expensed as incurred with the exception of stock-based compensation, which is recognized over the requisite service period. Marketing and Advertising Expenses —Marketing and advertising expenses consist of customer acquisition expenses, brand costs, paid advertising, and personnel related costs for brand teams. For customer acquisition expenses, the Company primarily generates loan origination leads through third-party financial service websites for which they incur “pay-per-click” expenses. A majority of the Company’s marketing and advertising expenses are incurred from leads purchased from these third-party financial service websites. Personnel related expenses include compensation and related benefits, stock-based compensation, and allocated occupancy expenses and related overhead based on headcount. Marketing and advertising expenses are expensed as incurred with the exception of stock-based compensation, which is recognized over the requisite service period. Technology and Product Development Expenses —Technology and product development expenses consist of employee compensation, amortization of capitalized internal-use software costs related to the Company’s technology platform, and expenses related to vendors engaged in product management, design, development, and testing of the Company’s websites and products. Employee compensation consists of stock-based compensation and benefits related to the Company’s technology team, product and creative team, and engineering team. Technology and product development expenses also include allocated occupancy expenses and related overhead based on headcount. Technology and product development expenses are expensed as incurred with the exception of stock-based compensation, which is recognized over the requisite service period. Segments —The Company has one reportable segment. The Company’s chief operating decision maker, the Chief Executive Officer, reviews financial information presented on a company-wide basis for purposes of allocating resources and evaluating financial performance. Emerging Growth Company and Smaller Reporting Company Status —Under the Jumpstart Our Business Startups Act of 2012 (“ JOBS Act”), emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until those standards apply to private companies. The JOBS Act does not preclude an emerging growth company from early adopting new or revised accounting standards. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that the Company (i) is no longer an emerging growth company or (ii) it affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, the consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. Better’s consolidated revenues were below $1.235 billion for the year ended December 31, 2022. Aurora had no consolidated revenues for the year ended December 31, 2022 and qualified as an emerging growth company. As a result, Better Home & Finance qualifies as an emerging growth company and is eligible for relief from regulatory requirements provided to emerging growth companies. The Company also is a smaller reporting company, as defined in the rules under the Securities Exchange Act of 1934 (the “Exchange Act”). Even after the Company no longer qualifies as an emerging growth company, the Company may still qualify as a smaller reporting company, which would allow it to continue taking advantage of many of the same exemptions from disclosure requirements, including reduced disclosure obligations regarding executive compensation in the Comp

Business Combination and Asset Acquisition [Abstract]
Business Combination	3. Business Combination The Business Combination has been accounted for as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, Aurora was treated as the “acquired” company for financial reporting purposes. Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of Better issuing stock for the net assets of Aurora, accompanied by a recapitalization. The net assets of Aurora were recorded at fair value (which approximated historical cost considering the nature of the assets transferred), with no goodwill or other intangible assets recorded. Operations prior to the Business Combination are those of Better. At the Closing of and in connection with the Business Combination, the following occurred: • Exchange of Legacy Better Stock —Each outstanding share of Better common stock prior to the Business Combination (“Legacy Better Stock”), each warrant to purchase preferred stock was exercised and all series of preferred stock were converted to common stock and exchanged for approximately 3.06 shares (the "Exchange Ratio") of the Company’s common stock. Outstanding options to purchase Legacy Better common stock and restricted stock units ("RSUs") were converted into the right to receive options or warrants to purchase shares of Class B common stock or RSUs representing the right to receive shares of Class B common stock, as applicable, on the same terms and conditions that are in effect with respect to such options or RSUs on the day of the closing of the Business Combination, subject to adjustments using the Exchange Ratio. • Private and Public Warrants —6,075,047 redeemable public warrants to acquire shares of Aurora (“Public Warrants”), together with 3,733,358 private warrants to acquire shares of Aurora (“Private Warrants” and, together with the Public Warrants, the “Warrants”), have converted into warrants to acquire shares of Better Home & Finance Class A common stock. As contemplated by the Sponsor Agreement, dated as of May 10, 2021, by and among Aurora and Novator Capital Sponsor Ltd. (“Sponsor”) (as amended, the “Sponsor Agreement”), Sponsor forfeited 1,715,014 Private Warrants, effective as of the Closing Date, which comprised 50% of the Private Warrants held by Sponsor on May 10, 2021. Each Warrant entitles the holder to purchase one share of the Company’s Class A common stock at an exercise price of $11.50 per share, subject to certain adjustments. The Warrants became exercisable at any time commencing 30 days after the completion of the Business Combination (which for the avoidance of doubt was September 21, 2023), and will expire five years after the Business Combination or earlier upon redemption or liquidation. • Sponsor locked-up Shares —Pursuant to the Sponsor Agreement, the Sponsor forfeited upon Closing 50% of the Aurora private warrants and 20% of the Sponsor’s shares of Better Home & Finance Class A common stock as of the Closing became subject to transfer restrictions, contingent upon the price of Better Home & Finance Class A common stock exceeding certain thresholds (the “Sponsor Locked-Up Shares”). The Sponsor Locked-Up Shares will be released in three tranches if the volume weighted average price (the “VWAP”) of Better Home & Finance Class A common stock exceeds certain price thresholds: (i) one-third of such shares will be released if VWAP for any 20 trading days during any consecutive 30-trading day period exceeds $12.50 per share, (ii) one-third of such shares will be released if the VWAP for any 20 trading days during any consecutive 30-trading day period exceeds $15.00 per share, and (iii) one-third of such shares will be released if the VWAP for any 20 trading days during any consecutive 30-trading day period exceeds $17.50 per share. In addition to the transfer restriction, upon certain change in control events included in the Sponsor Agreement, if there is a change in control event within five years following the Closing, the shares which have not reached the thresholds stated above will be forfeited. If after five years there is no such change in control event, the lock-up period will go on in perpetuity until the price thresholds are met. • Aurora Trust Account —The Company received gross cash consideration of $21.4 million as a result of the reverse recapitalization as well as $0.2 million from Aurora’s operating cash account. • Post-Closing Convertible Notes —The Company received $528.6 million from SoftBank as a result of issuing notes, see Note 10 for further details. • Sponsor Share Purchase —The purchase for $17.0 million by the Sponsor of 1.7 million shares of Better Home & Finance Class A common stock. • Conversion of Convertible Preferred Stock and Exercise of Convertible Preferred Stock Warrants —See Note 17 for further details. • Conversion of Pre-Closing Bridge Notes —See Note 10 for further details. • Transaction or Exchange costs —The Company incurred $21.4 million of equity issuance costs, consisting of financial advisory, legal, share registration, and other professional fees, which are recorded to additional paid-in capital as a reduction of transaction proceeds.

Restructuring and Related Activities [Abstract]
Restructuring and Impairments	5. Restructuring and Impairments In December 2021, the Company initiated an operational restructuring program that included plans for costs reductions in response to a difficult interest rate environment as well as a slowing housing market. The restructuring program, which continued during the nine months ended September 30, 2023, consists of reductions in headcount and any associated costs which primarily include one-time employee termination benefits. The Company expects the restructuring initiatives to continue at least through the end of 2023. Due to the reduced headcount, the Company has also reduced its real estate footprint. The Company has impaired right-of-use assets related to office space that is no longer in use or has been completely abandoned. Leases where the Company is unable to terminate or amend the lease with the landlord remain on the balance sheet under lease liabilities. In February 2023, the Company entered into a lease amendment with a landlord to surrender an office floor and reassign the lease to a third party. The amendment relieves the Company of the primary obligation under the original lease and as such is considered a termination of the original lease. In February 2023, the Company impaired the right-of-use asset of $13.0 million and removed the lease liability of $13.0 million related to one of the office spaces and as part of the amendment the Company incurred a loss of $5.3 million which included a $4.7 million payment in cash to the third party and $0.6 million other related fees to terminate the lease early. For the three months ended September 30, 2023 and 2022, the Company impaired property and equipment of none and $0.2 million, respectively, which was related to termination of lease agreement and sale of laptops resulting from a reduction in the workforce. For the nine months ended September 30, 2023 and 2022, the Company impaired property and equipment of $4.8 million and $3.1 million, respectively, which was related to the termination of the lease agreements and sale of laptops resulting from a reduction in the workforce. The Company assessed the loan commitment asset for impairment as there were factors that indicated that it was probable that the asset had been impaired on September 30, 2022 as the probability of the Company meeting the criteria to draw on the Post-Closing Convertible declined. For the three and nine months ended September 30, 2023 and 2022, the Company’s restructuring and impairment expenses consists of the following: Three Months Ended September 30, Nine Months Ended September 30, (Amounts in thousands) 2023 2022 2023 2022 Employee one-time termination benefits $ 765 $ 5,277 $ 2,320 $ 99,291 Impairment of loan commitment asset — 38,330 — 105,604 Impairments of Right-of-Use Assets — 1,897 413 4,391 Real estate restructuring loss — — 5,284 — (Gain) on lease settlement (86) — (1,063) — Impairment of property and equipment — 197 4,844 3,124 Other impairments 80 80 Total Restructuring and Impairments $ 679 $ 45,781 $ 11,798 $ 212,490 As of September 30, 2023 and December 31, 2022, respectively, the Company had an immaterial liability related to employee one-time termination benefits that were yet to be paid. The cumulative amount of one-time termination benefits, impairment of loan commitment asset, impairment of right-of-use assets, and impairment of property and equipment as of September 30, 2023 is $121.6 million, $105.6 million, $6.6 million, and $8.9 million, respectively.

The Company had none and $2.0 million of unamortized warrant issuance related discount and debt issuance costs as of September 30, 2023 and December 31, 2022, respectively . In February 2023, the Company entered into a loan and security agreement (the “2023 Credit Facility”) with Clear Spring Life and Annuity Company, an entity affiliated with the previous agent and acting as an agent for such lenders (together, the “Lender”) to amend its previously existing loan and security agreement (the “2021 Credit Facility”). The terms of the 2023 Credit Facility granted relief from the acceleration of payments under minimum revenue triggers from the 2021 Credit Facility. The 2023 Credit Facility split the principal balance into two tranches, tranche “AB” in the amount of $96.7 million and Tranche “C” in the amount of $26.9 million.

Related Party Transactions [Abstract]
Related Party Transactions	11. Related Party Transactions The Company has entered into a number of commercial agreements with related parties, which management believes provide the Company with products or services that are beneficial to its commercial objectives. Often these products and services have been tailored to the Company’s specific needs or are part of new pilot programs, both for the Company and the counterparty, for which there are not clear alternative vendors offering comparable services to compare pricing with. It is reasonable to assume that none of these related party commercial agreements were structured at arm’s length and therefore may be beneficial to the counterparty. 1/0 Capital —The Company is a party to an employee and expense allocation agreement with 1/0 Capital, LLC (“1/0 Capital”), an entity affiliated with 1/0 Real Estate, LLC (“1/0 Real Estate”) (an entity wholly owned by 1/0 Holdco, in which Vishal Garg, the Chief Executive Officer of the Company, and the Company’s executive officers each hold a more than five percent ownership interest). Under the employee and expense allocation agreement, 1/0 Capital provides the Company access to certain employees in exchange for reasonable consideration in the form of fees based on their time, as well as IT support services. Any intellectual property created under the agreement by 1/0 Capital employees working on behalf of the Company belongs to the Company. The term of the agreement will continue in perpetuity. The services provided by 1/0 Capital are not integral to the Company’s technology platform and amounts incurred are not material to the Company. In connection with this agreement, the Company reduced the accrued expense by $27.0 thousand and $187.3 thousand in the three months ended September 30, 2023 and 2022, respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	12. Commitments and Contingencies Litigation —The Company, among other things, engages in mortgage lending, title and settlement services, and other financial technology services. The Company operates in a highly regulated industry and may be subject to various legal and administrative proceedings concerning matters that arise in the normal and ordinary course of business, including inquiries, complaints, audits, examinations, investigations, employee labor disputes, and potential enforcement actions from regulatory agencies. While the ultimate outcome of these matters cannot be predicted with certainty due to inherent uncertainties in litigation, management is of the opinion that these matters will not have a material impact on the condensed consolidated financial statements of the Company. The Company accrues for losses when they are probable to occur and such losses are reasonably estimable, and discloses pending litigation if the Company believes a possibility exists that the litigation will have a material effect on its financial results. Legal costs expected to be incurred are accounted for as they are incurred. The Company is currently a party to pending legal claims and proceedings regarding an employee related labor dispute brought forth during the third quarter of 2020. The dispute alleges that the Company has failed to pay certain employees for overtime and is in violation of the Fair Labor Standards Act and labor laws in the State of California and the State of Florida. The case is still in its early stages and has not yet reached the class certification stage and as such the ultimate outcome cannot be predicted with certainty due to inherent uncertainties in the legal claims. As part of the dispute, the Company included an estimated liability of $8.4 million as of both September 30, 2023 and December 31, 2022, which is included in accounts payable and accrued expenses on the condensed consolidated balance sheets. No additional expense was accrued for the nine months ended September 30, 2023. During the first quarter of 2023, the Company settled its employee related labor dispute in the State of Florida for an immaterial amount. In September 2022, the former Head of Sales and Operations of the Company, Sarah Pierce, filed litigation against the Company, the Company’s founder and CEO Vishal Garg, and the Company’s Chief Administrative Officer and Senior Counsel Nicholas Calamari. The complaint alleges several causes of action including: violation of certain state labor laws, breach of fiduciary duty and defamation against Mr. Garg, aiding and abetting breach of fiduciary duty against Mr. Calamari, and intentional infliction of emotional distress against Mr. Garg and Mr. Calamari. On September 29, 2023, the Court filed an Order granting the Company's motions to dismiss in part and denying the Company’s motions to dismiss in part. The following motions were granted: (i) the Company’s motion to dismiss Ms. Pierce’s Sarbanes-Oxley claim was granted; (ii) the Company’s motion to dismiss Ms. Pierce’s Dodd-Frank claim was granted; (iii) Mr. Garg and Mr. Calamari’s motion to dismiss Ms. Pierce’s claim for breach of fiduciary duty was granted; (iv) the Company's motion to dismiss Ms. Pierce’s defamation claim was granted; (v) Mr. Garg and Mr. Calamari’s motion to dismiss Ms. Pierce’s claim for intentional infliction of emotional distress was granted; (vi) Mr. Garg and Mr. Calamari’s motion to dismiss Ms. Pierce’s claim for tortious interference with contract was granted; and (vii) the Company’s motion to dismiss Ms. Pierce’s breach of contract claim was granted. The Company’s motion to dismiss Ms. Pierce's claim of retaliation was dismissed. Mr. Garg’s motion to dismiss Ms. Pierce’s defamation claim was denied, and the Company’s motion to dismiss Ms. Pierce’s defamation claim under the theory of respondeat superior was denied. The Company intends to vigorously defend this action. Regulatory Matters —In the third quarter of 2021, following third-party audits of samples of loans produced during the fiscal years 2018, 2019, and 2021, the Company became aware of certain TILA-RESPA Integrated Disclosure (“TRID”) defects in the loan production process that resulted in the final closing costs disclosed in the closing disclosure, in some instances, being greater than those disclosed in the loan estimate. Some of these defects were outside applicable tolerances under the TRID rule, which resulted in potential overcharges to consumers. As of September 30, 2023 and December 31, 2022, the Company included an estimated liability of $9.3 million and $11.9 million, respectively, within accounts payable and accrued expenses on the condensed consolidated balance sheets. For the three months ended September 30, 2023, the Company reduced the accrual for these potential TRID defects by $3.0 million and is included within mortgage platform expenses in the condensed consolidated statement of operations and comprehensive loss. For the nine months ended September 30, 2023, the Company reduced the accrual for these potential TRID defects by $2.7 million and is included within mortgage platform expenses in the condensed consolidated statement of operations and comprehensive loss. This accrual is the Company’s best estimate of potential exposure on the larger population of loans based on the results obtained by the audited sample. The accrued amounts are for estimated refunds potentially due to consumers for TRID tolerance errors for loans produced from 2018 through 2022. The Company completed a TRID audit of 2022 files and is continuing to remediate TRID tolerance defects as necessary. In the second quarter of 2022, Better and Aurora received a voluntary request for documents from the Division of Enforcement of the Securities and Exchange Commission (the “SEC”) and subsequently received several subpoenas, indicating that it is conducting an investigation relating to Aurora and Better to determine if violations of the federal securities laws had occurred. The SEC requested that Aurora and Better provide the SEC with certain information and documents. The voluntary and subpoena requests covered, among other things, certain aspects of Better’s business and operations, certain matters relating to certain actions and circumstances of the Company’s founder and Chief Executive Officer, Vishal Garg, and his other business activities, related party transactions, public statements made about the Company’s proprietary mortgage platform, Better’s financial condition, and allegations made in litigation filed by Sarah Pierce, Better’s former Head of Sales and Operations. On August 3, 2023, the SEC Division of Enforcement informed Aurora and Better that it has concluded its previously announced investigation and that the SEC does not intend to recommend an enforcement action against Aurora or Better. Loan Commitments —The Company enters into IRLCs to fund mortgage loans, at specified interest rates and within a specified period of time, with potential borrowers who have applied for a loan and meet certain credit and underwriting criteria. As of September 30, 2023 and December 31, 2022, the Company had outstanding commitments to fund mortgage loans in notional amounts of approximately $211.9 million and $225.4 million, respectively. The IRLCs derived from those notional amounts are recorded within derivative assets and liabilities, at fair value as of September 30, 2023 and December 31, 2022, respectively, on the condensed consolidated balance sheets. See Note 15. Forward Sale Commitments —In the ordinary course of business, the Company enters into contracts to sell existing LHFS or loans committed but yet to be funded into the secondary market at specified future dates. As of September 30, 2023 and December 31, 2022, the Company had outstanding forward sales commitment contracts of notional amounts of approximately $294.0 million and $422.0 million, respectively. The forward sales commitments derived from those notional amounts are recorded within derivative assets and liabilities, at fair value as of September 30, 2023 and December 31, 2022, respectively, on the condensed consolidated balance sheets. See Note 15. Concentrations —See below for areas considered to be concentrations of credit risk for the Company: Significant loan purchasers are those which represent more than 10% of the Company’s loan volume. During the three months ended September 30, 2023, the Company had three loan purchasers that accounted for 56%, 22% and 11% of loans sold by the Company. During the three months ended September 30, 2022, the Company had one loan purchaser that accounted for 59% of loans sold by the Company. During the nine months ended September 30, 2023 and 2022, the Company had one loan purchaser that accounted for 68% and 65% of loans sold by the Company. Concentrations of credit risk associated with the LHFS carried at fair value are limited due to the large number of borrowers and their dispersion across many geographic areas throughout the United States. As of September 30, 2023, the Company originated 12% and 11% of its LHFS secured by properties in Texas and Florida, respectively. As of December 31, 2022, the company originated 11% of its LHFS secured by properties in each of California and Texas and 10% of its LHFS secured by properties in Florida. The Company maintains cash and cash equivalent balances at various financial institutions. Cash accounts at each bank are insured by the Federal Deposit Insurance Corporation for amounts up to $0.25 million. As of September 30, 2023 and December 31, 2022, the majority of the Company’s cash and cash equivalent balances are in excess of the insured limits at various financial institutions. Advanced Loan Origination Fees (Deferred Revenue) —Deferred revenue primarily consists of advance payments for loan origination and servicing on behalf of an integrated relationship partner. The total advance was for $50.0 million and were recognized in revenue starting in August 2022 through August 2023. The Company must repay the advance in three tranches, $20.0 million due December 2022, $15.0 million due April 2023, and $15.0 million due October 2023, each to be reduced by the amount of loan origination revenue earned between the tranches. The Company repaid $12.9 million of the first tranche after reductions for loan origination revenue earned within mortgage platform revenue from August 2022 through December 31, 2022. In April 2023, the Company repaid $12.7 million of the second tranche after reductions for loan origination revenue earned within mortgage platform revenue from January 2023 through March 2023. As of September 30, 2023 and December 31, 2022, the Company included deferred revenue of $12.9 million and $30.0 million, respectively within other liabilities on the condensed consolidated balance sheets after reductions for loan origination revenue earned within mortgage platform revenue. Subsequent to September 30, 2023, in October 2023, the Company paid off $12.9 million of the third tranche. Escrow Funds —In accordance with its lender obligations, the Company maintains a separate escrow bank account to hold borrower funds pending future disbursement. The Company administers escrow deposits representing undisbursed amounts received for payment of property taxes, insurance and principal, and interest on mortgage loans held for sale. The Company also administers customer deposits in relation to other non-mortgage products and services that the Company offers. These funds are shown as restricted cash and there is a corresponding escrow payable on the consolidated balance sheet, as they are being held on behalf of the borrower or customer. The balance in these accounts as of September 30, 2023 and December 31, 2022 was $3.2 million and $8.0 million, respectively. In some instances the Company may administer funds that are legally owned by a third-party which are excluded from the condensed consolidated balance sheets which amounted to none and $0.3 million as of September 30, 2023 and December 31, 2022, respectively. Customer Deposits —In relation to the Company’s banking activities tied to the Birmingham acquisition in the U.K., the Company offers individual savings accounts and other depository products with differing maturities and interest rates to its customers. The balance of customer deposits as of September 30, 2023 and December 31, 2022 was $9.9 million and none, respectively on the condensed consolidated balance sheets. 13. Risks and Uncertainties In the normal course of business, companies in the mortgage lending industry encounter certain economic and regulatory risks. Economic risks include credit risk and interest rate risk, in either a rising or declining interest rate environment. Credit risk is the risk of default that may result from the borrowers’ inability or unwillingness to make contractually required payments during the period in which loans are being held for sale by the Company. Interest Rate Risk —The Company is subject to interest rate risk in a rising interest rate environment, as the Company may experience a decrease in loan production, as well as decreases in the fair value of LHFS, loan applications in process with locked-in rates, and commitments to originate loans, which may negatively impact the Company’s operations. To preserve the value of such fixed-rate loans or loan applications in process with locked-in rates, agreements are executed for best effort or mandatory loan sales to be settled at future dates with fixed prices. These loan sales take the form of short-term forward sales of mortgage-backed securities and commitments to sell loans to loan purchasers. Alternatively, in a declining interest rate environment, customers may withdraw their loan applications that include locked-in rates with the Company. Additionally, when interest rates decline, interest income received from LHFS will decrease. The Company uses an interest rate hedging program to manage these risks. Through this program, mortgage-backed securities are purchased and sold forward. For all counterparties with open positions as of September 30, 2023, in the event that the Company does not deliver into the forward-delivery commitments, they can be settled on a net basis. Net settlements entail paying or receiving cash based upon the change in market value of the existing instrument. The Company currently uses forward sales of mortgage-backed securities, interest rate commitments from borrowers, and mandatory and/or best-efforts forward commitments to sell loans to loan purchasers to protect the Company from interest rate fluctuations. These short-term instruments, which do not require any payments to be paid to the counterparty in connection with the execution of the commitments, are generally executed simultaneously. Credit Risk —The Company’s hedging program is not designated as formal hedging from an accounting standpoint, contains an element of risk because the counterparties to its mortgage securities transactions may be unable to meet their obligations. While the Company does not anticipate nonperformance by any counterparty, it is exposed to potential credit losses in the event the counterparty fails to perform. The Company’s exposure to credit risk in the event of default by the counterparty is the difference between the contract and the current market price. The Company minimizes its credit risk exposure by limiting the counterparties to well-established banks and securities dealers who meet established credit and capital guidelines. Loan Repurchase Reserve —The Company sells loans to loan purchasers without recourse. As such, the loan purchasers have assumed the risk of loss or default by the borrower. However, the Company is usually required by these loan purchasers to make certain standard representations and warranties relating to the loan for up to three years post sale. To the extent that the Company does not comply with such representations, or there are early payment defaults, the Company may be required to repurchase the loans or indemnify these loan purchasers for losses. In addition, if loans pay-off within a specified time frame the Company may be required to refund a portion of the sales proceeds to the loan purchasers. The Company repurchased $3.6 million ( 11 l oans) and $37.9 million ( 82 l oans) in unpaid principal balance of loans during the three months ended September 30, 2023 and 2022, respectively, related to its loan repurchase obligations. The Company repurchased $20.8 million (52 loans) and $97.0 million (221 loans) in unpaid principal balance of loans during the nine months ended September 30, 2023 and 2022, respectively, related to its loan repurchase obligations. The Company’s loan repurchase reserve as of September 30, 2023 and December 31, 2022 was $21.8 million and $26.7 million, respectively, and is included within other liabilities on the condensed consolidated balance sheets. The provision for the loan repurchase reserve is included within mortgage platform expenses on the condensed consolidated statement of operations and comprehensive loss. The following presents the activity of the Company’s loan repurchase reserve: Three Months Ended September 30, Nine Months Ended September 30, (Amounts in thousands) 2023 2022 2023 2022 Loan repurchase reserve at beginning of period $ 21,832 $ 21,070 $ 26,745 $ 17,540 Provision 866 11,683 178 25,125 Charge-offs (945) (9,754) (5,170) (19,667) Loan repurchase reserve at end of period $ 21,753 $ 22,999 $ 21,753 $ 22,999 Borrowing Capacity —The Company funds the majority of mortgage loans on a short-term basis through committed and uncommitted warehouse lines as well as from operations for any amounts not advanced by warehouse lenders. As a result, the Company’s ability to fund current operations depends on its ability to secure these types of short-term financings. If the Company’s principal lenders decided to terminate or not to renew any of the warehouse lines with the Company, the loss of borrowing capacity could be detrimental to the Company’s condensed consolidated financial statements unless the Company found a suitable alternative source.

Risks and Uncertainties [Abstract]
Risks and Uncertainties	12. Commitments and Contingencies Litigation —The Company, among other things, engages in mortgage lending, title and settlement services, and other financial technology services. The Company operates in a highly regulated industry and may be subject to various legal and administrative proceedings concerning matters that arise in the normal and ordinary course of business, including inquiries, complaints, audits, examinations, investigations, employee labor disputes, and potential enforcement actions from regulatory agencies. While the ultimate outcome of these matters cannot be predicted with certainty due to inherent uncertainties in litigation, management is of the opinion that these matters will not have a material impact on the condensed consolidated financial statements of the Company. The Company accrues for losses when they are probable to occur and such losses are reasonably estimable, and discloses pending litigation if the Company believes a possibility exists that the litigation will have a material effect on its financial results. Legal costs expected to be incurred are accounted for as they are incurred. The Company is currently a party to pending legal claims and proceedings regarding an employee related labor dispute brought forth during the third quarter of 2020. The dispute alleges that the Company has failed to pay certain employees for overtime and is in violation of the Fair Labor Standards Act and labor laws in the State of California and the State of Florida. The case is still in its early stages and has not yet reached the class certification stage and as such the ultimate outcome cannot be predicted with certainty due to inherent uncertainties in the legal claims. As part of the dispute, the Company included an estimated liability of $8.4 million as of both September 30, 2023 and December 31, 2022, which is included in accounts payable and accrued expenses on the condensed consolidated balance sheets. No additional expense was accrued for the nine months ended September 30, 2023. During the first quarter of 2023, the Company settled its employee related labor dispute in the State of Florida for an immaterial amount. In September 2022, the former Head of Sales and Operations of the Company, Sarah Pierce, filed litigation against the Company, the Company’s founder and CEO Vishal Garg, and the Company’s Chief Administrative Officer and Senior Counsel Nicholas Calamari. The complaint alleges several causes of action including: violation of certain state labor laws, breach of fiduciary duty and defamation against Mr. Garg, aiding and abetting breach of fiduciary duty against Mr. Calamari, and intentional infliction of emotional distress against Mr. Garg and Mr. Calamari. On September 29, 2023, the Court filed an Order granting the Company's motions to dismiss in part and denying the Company’s motions to dismiss in part. The following motions were granted: (i) the Company’s motion to dismiss Ms. Pierce’s Sarbanes-Oxley claim was granted; (ii) the Company’s motion to dismiss Ms. Pierce’s Dodd-Frank claim was granted; (iii) Mr. Garg and Mr. Calamari’s motion to dismiss Ms. Pierce’s claim for breach of fiduciary duty was granted; (iv) the Company's motion to dismiss Ms. Pierce’s defamation claim was granted; (v) Mr. Garg and Mr. Calamari’s motion to dismiss Ms. Pierce’s claim for intentional infliction of emotional distress was granted; (vi) Mr. Garg and Mr. Calamari’s motion to dismiss Ms. Pierce’s claim for tortious interference with contract was granted; and (vii) the Company’s motion to dismiss Ms. Pierce’s breach of contract claim was granted. The Company’s motion to dismiss Ms. Pierce's claim of retaliation was dismissed. Mr. Garg’s motion to dismiss Ms. Pierce’s defamation claim was denied, and the Company’s motion to dismiss Ms. Pierce’s defamation claim under the theory of respondeat superior was denied. The Company intends to vigorously defend this action. Regulatory Matters —In the third quarter of 2021, following third-party audits of samples of loans produced during the fiscal years 2018, 2019, and 2021, the Company became aware of certain TILA-RESPA Integrated Disclosure (“TRID”) defects in the loan production process that resulted in the final closing costs disclosed in the closing disclosure, in some instances, being greater than those disclosed in the loan estimate. Some of these defects were outside applicable tolerances under the TRID rule, which resulted in potential overcharges to consumers. As of September 30, 2023 and December 31, 2022, the Company included an estimated liability of $9.3 million and $11.9 million, respectively, within accounts payable and accrued expenses on the condensed consolidated balance sheets. For the three months ended September 30, 2023, the Company reduced the accrual for these potential TRID defects by $3.0 million and is included within mortgage platform expenses in the condensed consolidated statement of operations and comprehensive loss. For the nine months ended September 30, 2023, the Company reduced the accrual for these potential TRID defects by $2.7 million and is included within mortgage platform expenses in the condensed consolidated statement of operations and comprehensive loss. This accrual is the Company’s best estimate of potential exposure on the larger population of loans based on the results obtained by the audited sample. The accrued amounts are for estimated refunds potentially due to consumers for TRID tolerance errors for loans produced from 2018 through 2022. The Company completed a TRID audit of 2022 files and is continuing to remediate TRID tolerance defects as necessary. In the second quarter of 2022, Better and Aurora received a voluntary request for documents from the Division of Enforcement of the Securities and Exchange Commission (the “SEC”) and subsequently received several subpoenas, indicating that it is conducting an investigation relating to Aurora and Better to determine if violations of the federal securities laws had occurred. The SEC requested that Aurora and Better provide the SEC with certain information and documents. The voluntary and subpoena requests covered, among other things, certain aspects of Better’s business and operations, certain matters relating to certain actions and circumstances of the Company’s founder and Chief Executive Officer, Vishal Garg, and his other business activities, related party transactions, public statements made about the Company’s proprietary mortgage platform, Better’s financial condition, and allegations made in litigation filed by Sarah Pierce, Better’s former Head of Sales and Operations. On August 3, 2023, the SEC Division of Enforcement informed Aurora and Better that it has concluded its previously announced investigation and that the SEC does not intend to recommend an enforcement action against Aurora or Better. Loan Commitments —The Company enters into IRLCs to fund mortgage loans, at specified interest rates and within a specified period of time, with potential borrowers who have applied for a loan and meet certain credit and underwriting criteria. As of September 30, 2023 and December 31, 2022, the Company had outstanding commitments to fund mortgage loans in notional amounts of approximately $211.9 million and $225.4 million, respectively. The IRLCs derived from those notional amounts are recorded within derivative assets and liabilities, at fair value as of September 30, 2023 and December 31, 2022, respectively, on the condensed consolidated balance sheets. See Note 15. Forward Sale Commitments —In the ordinary course of business, the Company enters into contracts to sell existing LHFS or loans committed but yet to be funded into the secondary market at specified future dates. As of September 30, 2023 and December 31, 2022, the Company had outstanding forward sales commitment contracts of notional amounts of approximately $294.0 million and $422.0 million, respectively. The forward sales commitments derived from those notional amounts are recorded within derivative assets and liabilities, at fair value as of September 30, 2023 and December 31, 2022, respectively, on the condensed consolidated balance sheets. See Note 15. Concentrations —See below for areas considered to be concentrations of credit risk for the Company: Significant loan purchasers are those which represent more than 10% of the Company’s loan volume. During the three months ended September 30, 2023, the Company had three loan purchasers that accounted for 56%, 22% and 11% of loans sold by the Company. During the three months ended September 30, 2022, the Company had one loan purchaser that accounted for 59% of loans sold by the Company. During the nine months ended September 30, 2023 and 2022, the Company had one loan purchaser that accounted for 68% and 65% of loans sold by the Company. Concentrations of credit risk associated with the LHFS carried at fair value are limited due to the large number of borrowers and their dispersion across many geographic areas throughout the United States. As of September 30, 2023, the Company originated 12% and 11% of its LHFS secured by properties in Texas and Florida, respectively. As of December 31, 2022, the company originated 11% of its LHFS secured by properties in each of California and Texas and 10% of its LHFS secured by properties in Florida. The Company maintains cash and cash equivalent balances at various financial institutions. Cash accounts at each bank are insured by the Federal Deposit Insurance Corporation for amounts up to $0.25 million. As of September 30, 2023 and December 31, 2022, the majority of the Company’s cash and cash equivalent balances are in excess of the insured limits at various financial institutions. Advanced Loan Origination Fees (Deferred Revenue) —Deferred revenue primarily consists of advance payments for loan origination and servicing on behalf of an integrated relationship partner. The total advance was for $50.0 million and were recognized in revenue starting in August 2022 through August 2023. The Company must repay the advance in three tranches, $20.0 million due December 2022, $15.0 million due April 2023, and $15.0 million due October 2023, each to be reduced by the amount of loan origination revenue earned between the tranches. The Company repaid $12.9 million of the first tranche after reductions for loan origination revenue earned within mortgage platform revenue from August 2022 through December 31, 2022. In April 2023, the Company repaid $12.7 million of the second tranche after reductions for loan origination revenue earned within mortgage platform revenue from January 2023 through March 2023. As of September 30, 2023 and December 31, 2022, the Company included deferred revenue of $12.9 million and $30.0 million, respectively within other liabilities on the condensed consolidated balance sheets after reductions for loan origination revenue earned within mortgage platform revenue. Subsequent to September 30, 2023, in October 2023, the Company paid off $12.9 million of the third tranche. Escrow Funds —In accordance with its lender obligations, the Company maintains a separate escrow bank account to hold borrower funds pending future disbursement. The Company administers escrow deposits representing undisbursed amounts received for payment of property taxes, insurance and principal, and interest on mortgage loans held for sale. The Company also administers customer deposits in relation to other non-mortgage products and services that the Company offers. These funds are shown as restricted cash and there is a corresponding escrow payable on the consolidated balance sheet, as they are being held on behalf of the borrower or customer. The balance in these accounts as of September 30, 2023 and December 31, 2022 was $3.2 million and $8.0 million, respectively. In some instances the Company may administer funds that are legally owned by a third-party which are excluded from the condensed consolidated balance sheets which amounted to none and $0.3 million as of September 30, 2023 and December 31, 2022, respectively. Customer Deposits —In relation to the Company’s banking activities tied to the Birmingham acquisition in the U.K., the Company offers individual savings accounts and other depository products with differing maturities and interest rates to its customers. The balance of customer deposits as of September 30, 2023 and December 31, 2022 was $9.9 million and none, respectively on the condensed consolidated balance sheets. 13.

Basic and diluted earnings (loss) per share are presented together as the amounts for basic and diluted earnings (loss) per share are the same for each class of common stock. There were no preferred dividends declared or accumulated during the three months ended September 30, 2023 and 2022. There were no preferred dividends declared or accumulated during the nine months ended September 30, 2023 and 2022. The Company applies the two-class method which requires earnings available to common stockholders for the period to be allocated between common stock and participating securities based upon their respective rights to receive dividends as if all earnings for the period had been distributed. The Company’s outstanding convertible preferred stock is a participating security as the holders of such shares participate in earnings but do not contractually participate in the Company’s losses. The Company's potentially dilutive securities, which include stock options, convertible preferred stock that would have been issued under the if-converted method, warrants to purchase shares of common stock, warrants to purchase shares of preferred stock, and stock options exercised, not vested, have been excluded from the computation of diluted net loss per share, as the effect would be to reduce the net loss per share. The Company excluded the following securities, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share attributable to common stockholders for the periods indicated as including them would have had an anti-dilutive effect: Three Months Ended September 30, Nine Months Ended September 30, (Amounts in thousands) 2023 2022 2023 2022 Options to purchase common stock (1) 48,389 44,857 48,389 44,857 Convertible preferred stock (2) — 108,721 — 108,721 Pre-Closing Bridge Notes — 247,777 — 247,777 Warrants to purchase convertible preferred stock (1) — 6,649 — 6,649 Total 48,389 408,004 48,389 408,004 __________________ (1) Securities have an antidilutive effect under the treasury stock method.

(2) Fair value is based on the intrinsic value of the Company’s underlying stock price at each balance sheet date and includes certain assumptions with regard to volatility. Specific valuation techniques and inputs used in determining the fair value of each significant class of assets and liabilities are as follows: Mortgage Loans Held for Sale —The Company originates certain LHFS to be sold to loan purchasers and elected to carry these loans at fair value in accordance with ASC 825. The fair value is primarily based on the price obtained for other mortgage loans with similar characteristics. The changes in fair value of these assets are largely driven by changes in interest rates subsequent to loan funding and receipt of principal payments associated with the relevant LHFS. Derivative Assets and Liabilities —The Company uses derivatives to manage various financial risks. The fair values of derivative instruments are determined based on quoted prices for similar assets and liabilities, dealer quotes, and internal pricing models that are primarily sensitive to market observable data. The Company utilizes IRLCs and forward sale commitments. The fair value of IRLCs, which are related to mortgage loan commitments, is based on quoted market prices, adjusted by the pull-through factor, and includes the value attributable to the net servicing fee. The Company evaluated the significance and unobservable nature of the pull-through factor and determined that the classification of IRLCs should be Level 3 as of September 30, 2023 and December 31, 2022. Significant changes in the pull-through factor of the IRLCs, in isolation, could result in significant changes in the IRLCs’ fair value measurement. The value of IRLCs also rises and falls with changes in interest rates; for example, entering into interest rate lock commitments at low interest rates followed by an increase in interest rates in the market, will decrease the value of IRLC. The Company had purchases/issuances of approximately $0.1 million and $2.4 million of IRLCs during the three months ended September 30, 2023 and 2022, respectively. The Company had purchases/issuances of approximately $0.6 million and $5.0 million of IRLCs during the nine months ended September 30, 2023 and 2022, respectively. The number of days from the date of the IRLC to expiration of the rate lock commitment outstanding as of September 30, 2023 was approximately 60 days on average. The Company attempts to match the maturity date of the IRLCs with the forward commitments. Derivatives are presented in the condensed consolidated balance sheets under derivative assets, at fair value and derivative liabilities, at fair value. During the three months ended September 30, 2023, the Company recognized $0.9 million of loss and $5.0 million of gains related to changes in fair value of IRLCs and forward sale commitments, respectively. During the nine months ended September 30, 2023, the Company recognized $0.1 million and $8.4 million of gains related to changes in the fair value of IRLCs and forward sale commitments, respectively. During the three months ended September 30, 2022, the Company recognized $7.0 million of losses and $26.2 million of gains related to changes in the fair value of IRLCs and forward sale commitments, respectively. During the nine months ended September 30, 2022, the Company recognized $14.3 million of losses and $188.6 million of gains related to changes in the fair value of IRLCs and forward sale commitments, respectively. Gains and losses related to changes in the fair value of IRLCs and forward sale commitments are included in mortgage platform revenue, net within the condensed consolidated statements of operations and comprehensive loss. Unrealized activity related to changes in the fair value of forward sale commitments were $1.5 million of gains and $13.2 million of gains, included in the $5.0 million of gains and $26.2 million of gains, during the three months ended September 30, 2023 and 2022, respectively. Unrealized activity related to changes in the fair value of forward sale commitments were $0.8 million of gains and $14.1 million of gains, included in the $8.4 million of gains and $188.6 million of gains, during the nine months ended September 30, 2023 and 2022, respectively. The notional and fair value of derivative financial instruments not designated as hedging instruments were as follows: (Amounts in thousands) Notional Value Derivative Asset Derivative Liability Balance as of September 30, 2023 IRLCs $ 211,897 $ 211 $ 1,678 Forward commitments $ 294,000 3,506 — Total $ 3,717 $ 1,678 Balance as of December 31, 2022 IRLCs $ 225,372 $ 316 $ 1,828 Forward commitments $ 422,000 2,732 — Total $ 3,048 $ 1,828 Warrant and equity related liabilities— The warrant liability consists of Warrants and the Sponsor-Locked up Shares. The Warrants consist of Public Warrants and Private Warrants. The Public Warrants trade on the Nasdaq Capital Market under the ticker symbol “BETRW” and as such is considered a Level 1 input from an active market to derive the value. The Private Warrants and Sponsor-Locked up Shares, although not publicly traded on an active market, use inputs from the publicly traded Public Warrants and the Company’s publicly traded common stock, respectively, and are further calibrated using unobservable inputs representing Level 2 measurements within the fair value hierarchy. Convertible Preferred Stock Warrants —The Company issued Former Preferred Stock Warrants to certain investors and to the Lender under its corporate line of credit (see Note 10). The Company obtained a fair value analysis from a third party to assist in determination of the fair value of warrants. The Company used the Black-Scholes-Merton option-pricing model to estimate the fair value of the warrants at the issuance date and as of December 31, 2022, which is based on significant inputs not observable in the market representing a Level 3 measurement within the fair value hierarchy. Significant changes in the unobservable inputs could result in significant changes in the fair value of the convertible preferred stock warrants. The warrant valuation was based on the intrinsic value of the Company’s underlying stock price and included certain assumptions such as risk free rate, volatility rate, and expected term. Bifurcated Derivative —The Company’s Pre-Closing Bridge Notes included embedded features that were separately accounted for and were marked to fair value at each reporting period with changes included in change in fair value of bifurcated derivative on the consolidated statements of operations and comprehensive loss. The Company obtained a fair value analysis from a third party to assist in determination of the fair value of the bifurcated derivative. In estimating the fair value of the bifurcated derivative, management considered factors management believed were material to the valuation process, including, but not limited to, the price at which recent equity was issued by the Company to independent third parties or transacted between third parties, actual and projected financial results, risks, prospects, and economic and market conditions, among other factors. As there was no active market for the Company’s equity, the fair value of the bifurcated derivative was based on significant inputs not observable in the market representing a Level 3 measurement within the fair value hierarchy. Management believed the combination of these factors provided an appropriate estimate of the expected fair value and reflected the best estimate of the fair value of the bifurcated derivative. As of September 30, 2023 and December 31, 2022, Level 3 instruments include IRLCs, bifurcated derivative and convertible preferred stock warrants. The following table presents the rollforward of Level 3 IRLCs: Three Months Ended September 30, Nine Months Ended September 30, (Amounts in thousands) 2023 2022 2023 2022 Balance at beginning of period $ (514) $ 197 $ (1,513) $ 7,568 Change in fair value of IRLCs (953) (6,976) 46 (14,347) Balance at end of period $ (1,467) $ (6,779) $ (1,467) $ (6,779) The following table presents the rollforward of Level 3 bifurcated derivative: Three Months Ended September 30, Nine Months Ended September 30, (Amounts in thousands) 2023 2022 2023 2022 Balance at beginning of period $ 237,667 $ 277,777 $ 236,603 $ — Change in fair value of bifurcated derivative (237,667) 29,089 (236,603) 306,866 Balance at end of period $ — $ 306,866 $ — $ 306,866 The following table presents the rollforward of Level 3 convertible preferred stock warrants: Three Months Ended September 30, Nine Months Ended September 30, (Amounts in thousands) 2023 2022 2023 2022 Balance at beginning of period $ 2,830 $ 11,586 $ 3,096 $ 31,997 Exercises (2,830) — (2,830) — Change in fair value of convertible preferred stock warrants — (4,202) (266) (24,613) Balance at end of period $ — $ 7,384 $ — $ 7,384 Counterparty agreements for forward sale commitments contain master netting agreements, which contain a legal right to offset amounts due to and from the same counterparty and can be settled on a net basis.

In cases where quoted market prices are not available, fair values are based upon the estimation of discount rates to estimated future cash flows using market yields or other valuation methodologies. Considerable judgment is necessary to interpret market data and develop estimates of fair value in both inactive and orderly markets. Accordingly, fair values are not necessarily indicative of the amount the Company could realize on disposition of the financial instruments in a current market exchange. The use of market assumptions or estimation methodologies could have a material effect on the estimated fair value amounts. The estimated fair value of the Company’s cash and cash equivalents, restricted cash, warehouse lines of credit, and escrow funds and customer deposits approximates their carrying values as these financial instruments are highly liquid or short-term in nature. The following table presents the carrying amounts and estimated fair value of financial instruments that are not recorded at fair value on a recurring or non-recurring basis: September 30, 2023 December 31, 2022 (Amounts in thousands) Fair Value Level Carrying Amount Fair Value Carrying Amount Fair Value Short-term investments Level 1 $ 29,831 $ 29,884 $ — $ — Loans held for investment Level 3 $ 4,163 $ 4,649 $ — $ — Post-Closing Convertible Notes Level 3 $ 513,001 $ 252,796 $ — $ — Loan commitment asset Level 3 $ — $ — $ 16,119 $ 54,654 Pre-Closing Bridge Notes Level 3 $ — $ — $ 750,000 $ 269,067 Corporate line of credit Level 3 $ — $ — $ 144,403 $ 145,323 In determining the fair value of the Short term investments, management used observable inputs such as quoted prices in active markets for identical assets. The fair value of loans held for investment is determined by management estimates of the specific credit risk attributes of each pool of loans, in addition to the quoted secondary-market prices which account for the interest rate characteristics of each loan. The corporate line of credit was valued using a Black Derman Toy model which incorporates the option to prepay given the make-whole premium as well as other inputs such as risk-free rates and credit spreads. In determining the fair value of the loan commitment asset and the Pre-Closing Bridge Notes, management used factors that are material to the valuation process, including but not limited to, the price at which recent equity was issued by the Company to independent third parties or transacted between third parties, actual and projected financial results, risks, prospects, and economic and market conditions, among other factors. As a number of assumptions and estimates were involved that are largely unobservable, loans held for investment, loan commitment asset and Corporate line of credit were classified as Level 3 inputs within the fair value hierarchy.

Income Tax Disclosure [Abstract]
Income Taxes	16. Income Taxes On a consolidated basis, the Company recorded total income tax expense (benefit) of $0.7 million and $(0.1) million for the three months ended September 30, 2023 and 2022, respectively. The Company recorded total income tax expense of $2.5 million and $1.5 million for the nine months ended September 30, 2023 and 2022, respectively. The Company’s quarterly tax provision, and estimate of its annual effective tax rate, is subject to variation due to several factors, including the ability to accurately project the Company’s pre-tax income or loss for the year and the mix of earnings among various tax jurisdictions. The year-to-date effective tax rate, after discrete items, of (0.19)% for the three months ended September 30, 2023, changed from 0.02% for the three months ended September 30, 2022, as the Company is forecasting reduction in losses for 2023. The year-to-date effective tax rate, after discrete items, of (0.53)% for the nine months ended September 30, 2023, changed from (0.23)% for the nine months ended September 30, 2022, as the Company was subject to withholding taxes and is forecasting reduction in losses for 2023. The income tax expense for the three months ended September 30, 2023 primarily relates to the pre-tax income projections and dividend income withholding tax paid in certain foreign jurisdictions where the Company files standalone returns. The income tax expense for the nine months ended September 30, 2023 relates to the pre-tax income projections and dividend income withholding tax paid in certain foreign jurisdictions where the Company files standalone returns. As of each reporting date, the Company considers existing evidence, both positive and negative, that could impact management’s view with regard to future realization of deferred income tax assets. The Company is in a three year cumulative loss position as of September 30, 2023. Further, due to losses being estimated in the future, management continues to believe it is more likely than not that the benefit of the deferred income tax assets will not be realized. In recognition of this risk, the Company continues to provide a full valuation allowance on deferred income tax assets.

Regulatory Requirements	20. Regulatory Requirements The Company is subject to various local, state, and federal regulations related to its loan production by the various states it operates in, as well as federal agencies such as the Consumer Financial Protection Bureau (“CFPB”), HUD, and the FHA and is subject to the requirements of the agencies to which it sells loans, such as FNMA and FMCC. As a result, the Company may become involved in requests for information, periodic reviews, investigations, and proceedings by such various federal, state, and local regulatory bodies and agencies. The Company is required to meet certain minimum net worth, minimum capital ratio and minimum liquidity requirements, including those established by HUD, FMCC and FNMA. As of September 30, 2023, the Company was in compliance with all necessary requirements. Additionally, the Company is subject to other financial requirements established by FNMA, which include a limit for a decline in net worth and quarterly profitability requirements. On March 12, 2023 and subsequently on May 19, 2023, FNMA provided notification to the Company that the Company had failed to meet FNMA’s financial requirements due to the Company’s decline in profitability and material decline in net worth. The material decline in net worth and decline in profitability permit FNMA to declare a breach of the Company’s contract with FNMA. The Company, following certain forbearance agreements from FNMA that instituted additional financial requirements on the Company that are pending FNMA’s administrative process for completion, remains in compliance with these requirements as of the date hereof. FNMA and other regulators and GSEs are not required to grant any forbearances, amendments, extensions or waivers and may determine not to do so. As a result of failing to meet FNMA’s financial requirements, the Company has entered into a Pledge and Security Agreement with FNMA on July 24, 2023, to post additional cash collateral starting with $5.0 million which will be held through December 31, 2023. Each quarterly period after December 31, 2023, the required cash collateral will be calculated based on an amount equal to the greater of: (i) FNMA’s origination representation and warranty exposure to the Company, multiplied by the average repurchase success rate for FNMA single-family responsible parties or (ii) $5.0 million.

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	21. Subsequent Events The Company evaluated subsequent events from the date of the condensed consolidated balance sheets of September 30, 2023 through the date of the release of financial statements, and has determined that, there have been no subsequent events that require recognition or disclosure in the condensed consolidated financial statements, except as described i n Note 1, Note 6, Note 10, Note 12 and as follows: Nasdaq Delisting Notice —On October 12, 2023, the Company received a letter from the listing qualifications staff (the “Staff”) of Nasdaq notifying the Company that it is not in compliance with the minimum bid price requirement set forth in Nasdaq Listing Rule 5450(a)(1) (the “Bid Price Rule”) for continued listing. The Bid Price Rule requires listed securities to maintain a minimum bid price of $1.00 per share, and Nasdaq Listing Rule 5810(c)(3)(A) (the “Compliance Period Rule”) provides that a failure to meet the minimum bid price requirement exists if the deficiency continues for a period of 30 consecutive business days. The Notice has no immediate effect on the listing of the Company’s Class A common stock, par value $0.0001 per share (the “Common Stock”), which continues to trade on The Nasdaq Global Market under the symbol “BETR.” In accordance with the Compliance Period Rule, the Company has 180 calendar days to regain compliance. If the Company does not regain compliance during this 180-day period, then the Company may be eligible to transfer to The Nasdaq Capital Market and the Staff may grant the Company a second 180 calendar day period to regain compliance pursuant to the Compliance Period Rule, provided the Company meets the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, with the exception of the bid price requirement. In addition, the Company would be required to notify Nasdaq of its intent to cure the minimum bid price deficiency during the second compliance period by effecting a reverse stock split if necessary. The Company will continue to monitor the closing bid price of its Common Stock and seek to regain compliance with all applicable Nasdaq requirements within the allotted compliance periods.

Summary of Significant Accounting Policies (Policies)	Sep. 30, 2023
Accounting Policies [Abstract]
Basis of Presentation	The accompanying condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The Business Combination has been accounted for as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, Aurora was treated as the “acquired” company for financial reporting purposes. Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of Better issuing stock for the net assets of Aurora, accompanied by a recapitalization. All share amounts in periods prior to the Business Combination have been retroactively adjusted using the Exchange Ratio for the equivalent number of shares outstanding immediately after the Business Combination to effect the reverse recapitalization. The financials of Better are presented here for all comparative periods.In the opinion of the Company, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting of only normal recurring adjustments, necessary for a fair presentation of its financial position and its results of operations, changes in convertible preferred stock and stockholders’ equity (deficit) and cash flows. The results of operations and other information for the nine months ended September 30, 2023 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2023. The unaudited condensed consolidated financial statements presented herein should be read in conjunction with the audited consolidated financial statements and related notes of Better thereto for the year ended December 31, 2022.
Consolidation	The accompanying condensed consolidated financial statements include the accounts of the Company and its consolidated subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	The preparation of condensed consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.Significant items subject to such estimates and assumptions include the fair value of mortgage loans held for sale, the fair value of derivative assets and liabilities, including bifurcated derivatives, interest rate lock commitments and forward sale commitments, the determination of a valuation allowance on the Company’s deferred tax assets, capitalization of internally developed software and its associated useful life, determination of fair value of the Company’s common stock, stock option and RSUs at grant date, the fair value of acquired intangible assets and goodwill, the provision for loan repurchase reserves, the incremental borrowing rate used in determining lease liabilities and warrant liabilities.
Business Combinations	The Company includes the financial results of businesses that the Company acquires from the date of acquisition. The Company records all assets acquired and liabilities assumed at fair value, with the excess of the purchase price over the aggregate fair values recorded as goodwill. Determining the fair value of assets acquired and liabilities assumed requires management to use significant judgment and estimates including the selection of valuation methodologies, estimates of future revenue and cash flows, discount rates and selection of comparable companies. During the measurement period the Company may record adjustments to the assets acquired and liabilities assumed. Transaction costs associated with business combinations are expensed as incurred.
Short-term investments	Short term investments consist of fixed income securities, typically U.K. government treasury securities and U.K. government agency securities with maturities ranging from 91 days to one year. Management determines the appropriate classification of short-term investments at the time of purchase. Short-term investments reported as held-to-maturity are those investments which the Company has both the positive intent and ability to hold to maturity and are stated at amortized cost on the condensed consolidated balance sheets. All of the Company’s short term investments are classified as held to maturity. The Company has not recognized any impairments on these investments to date and any unrealized gains or losses on these investments are immaterial.
Allowance for Credit Losses	Held to Maturity (“HTM”) Short-term Investments—The Company's HTM Short-term investments are also required to utilize the Current Expected Credit Loss (“CECL”) approach to estimate expected credit losses. Management measures expected credit losses on short-term investments on a collective basis by major security types that share similar risk characteristics, such as financial asset type and collateral type adjusted for current conditions and reasonable and supportable forecasts. Management classifies the short term investments portfolio by security types, such as U.K. government agency.The U.K. government treasury securities and U.K. government agency securities are issued by U.K. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.K. government as to timely repayment of principal and interest, are highly rated by major rating agencies, and have a long history of no credit losses. Therefore, credit losses for these securities were immaterial as the Company does not currently expect any material credit losses.
Mortgage Loans Held for Sale, at Fair Value	The Company sells its mortgage loans held for sale (“LHFS”) to loan purchasers. These loans can be sold in one of two ways, servicing released, or servicing retained. If a loan is sold servicing released, the Company has sold all the rights to the loan and the associated servicing rights. If a loan is sold servicing retained, the Company has sold the loan and kept the servicing rights, and thus the Company is responsible for collecting monthly principal and interest payments and performing certain escrow services for the borrower. The loan purchaser, in turn, pays a fee for these services. The Company generally sells all of its loans servicing released. For interim servicing, the Company engages a third-party sub-servicer to collect monthly payments and perform associated services. LHFS consists of loans originated for sale by BMC. The Company elects the fair value option, in accordance with Accounting Standard Codification (“ASC”) 825 – Financial Instruments (“ASC 825”), for all LHFS with changes in fair value recorded in mortgage platform revenue, net in the condensed consolidated statements of operations and comprehensive loss. Management believes that the election of the fair value option for LHFS improves financial reporting by presenting the most relevant market indication of LHFS. The fair value of LHFS is based on market prices and yields at period end. The Company accounts for the gains or losses resulting from sales of mortgage loans based on the guidance of ASC 860-20 – Sales of Financial Assets (“ASC 860”). The Company issues interest rate lock commitments (“IRLC”) to originate mortgage loans and the fair value of the IRLC, adjusted for the probability that a given IRLC will close and fund, is recognized within mortgage platform revenue, net. Subsequent changes in the fair value of the IRLC are measured at each reporting period within mortgage platform revenue, net until the loan is funded. When the loan is funded, the IRLC is derecognized and the LHFS is recognized based on the fair value of the loan. The LHFS is subsequently remeasured at fair value at each reporting period and the changes in fair value are included within mortgage platform revenue, net until the loan is sold on the secondary market. When the loan is sold on the secondary market, the LHFS is derecognized and the gain/(loss) is included within mortgage platform revenue, net based on the cash settlement. LHFS are considered sold when the Company surrenders control over the loans. Control is considered to have been surrendered when the transferred loans have been isolated from the Company, are beyond the reach of the Company and its creditors, and the loan purchaser obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred loans. The Company typically considers the above criteria to have been met upon receipt of sales proceeds from the loan purchaser.
Loan Repurchase Reserve	The Company sells LHFS in the secondary market and in connection with those sales, makes customary representations and warranties to the relevant loan purchasers about various characteristics of each loan, such as the origination and underwriting guidelines, including but not limited to the validity of the lien securing the loan, property eligibility, borrower credit, income and asset requirements, and compliance with applicable federal, state and local laws. In the event of a breach of its representations and warranties, the Company may be required to repurchase the loan with the identified defects.The loan repurchase reserve on loans sold relates to expenses incurred due to the potential repurchase of loans, indemnification of losses based on alleged violations or representations and warranties, which are customary to the mortgage banking industry. Provisions for potential losses are charged to expenses and are included within mortgage platform expenses on the consolidated statements of operations and comprehensive loss. The loan repurchase reserve represents the Company’s estimate of the total losses expected to occur and is considered to be adequate by management based upon the Company’s evaluation of the potential exposure related to the loan sale agreements over the life of the associated loans sold. The Company records the loan repurchase reserve within other liabilities on the consolidated balance sheets.
Fair Value Measurements	Assets and liabilities recorded at fair value on a recurring basis on the condensed consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Fair value is defined as the exchange price that would be received for an asset or an exit price that would be paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The price used to measure fair value is not adjusted for transaction costs. The principal market is the market in which the Company would sell or transfer the asset with the greatest volume and level of activity for the asset. In determining the principal market for an asset or liability, it is assumed that the Company has access to the market as of the measurement date. If no market for the asset exists, or if the Company does not have access to the principal market, a hypothetical market is used. The authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows: Level 1 —Unadjusted quoted market prices in active markets for identical assets or liabilities; Level 2 —Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the asset or liability. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active; and Level 3 —Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Assets and liabilities measured at fair value on a recurring basis include LHFS, derivative assets and liabilities, including IRLCs and forward sale commitments, MSRs, bifurcated derivatives, convertible preferred stock warrants and warrant liabilities. Common stock warrants are measured at fair value at issuance only and are classified as equity on the condensed consolidated balance sheets. When developing fair value measurements, the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs. However, for certain instruments, the Company must utilize unobservable inputs in determining fair value due to the lack of observable inputs in the market, which requires greater judgment in measuring fair value. In instances where there is limited or no observable market data, fair value measurements for assets and liabilities are based primarily upon the Company’s own estimates, and the measurements
Loan Commitment Asset	Upon the Closing of the Business Combination and issuance of the Post-Closing Convertible Notes, the Loan commitment asset was reclassified as a discount to the Post-Closing Convertible Notes and was amortized as part of interest expense over the term of the note.
Debt	Warehouse lines of credit represent the outstanding balance of the Company’s warehouse borrowings collateralized by mortgage loans held for sale or related borrowings collateralized by restricted cash. Generally, warehouse lines of credit are used as interim, short-term financing which bears interest at a fixed margin over an index rate, such as the Secured Oversight Financing Rate (“SOFR”). The outstanding balance of the Company’s warehouse lines of credit will fluctuate based on its lending volume. The advances received under the warehouse lines of credit are based upon a percentage of the fair value or par value of the mortgage loans collateralizing the advance, depending upon the type of mortgage loan. Should the fair value of the pledged mortgage loans decline, the warehouse provider may require the Company to provide additional cash collateral or mortgage loans to maintain the required collateral level under the relevant warehouse line. The Company did not incur any significant issuance costs related to its warehouse lines of credit.As part of the Closing of the Business Combination, the Company issued convertible notes. Upon initial issuance, convertible notes are evaluated for redemption and conversion features that could result in embedded derivatives that require bifurcation from the notes. Upon initial issuance, any embedded derivatives are measured at fair value. Convertible notes proceeds are allocated between the carrying value of the notes and the fair value of embedded derivatives on the initial issuance date. Any portion of proceeds allocated to embedded derivatives are treated as reductions in, or discounts to, the carrying value of the convertible notes on the issuance date. Embedded derivatives are adjusted to fair value at each reporting period, with the change in fair value included within the consolidated statements of operations and comprehensive income (loss). See Note 10 for further details on the Company’s Post-Closing Convertible Notes.The Company had a line of credit arrangement with a third-party lender. Debt and other related issuance costs are deferred and amortized through the maturity date of the line of credit as interest and amortization on non-funding debt expense. Any modifications of the line of credit arrangement are analyzed as to whether they are an extinguishment or modification of debt on a lender-by-lender basis, which is determined by whether (1) the lender remains the same, and (2) the change in the debt terms is considered substantial. Gains and losses on debt modifications that are considered extinguishments are recognized in current earnings. Debt modifications that are not considered extinguishments are accounted for prospectively through yield adjustments, based on the revised terms (see Note 10).
Warrant Liabilities	The Company assumed publicly-traded warrants (“Public Warrants”) issued in Aurora’s initial public offering, private placement warrants issued by Aurora in connection with its formation and warrants attached to certain private placement units (collectively, the “Private Warrants” and, together with the Public Warrants, the “Warrants”). Each Warrant issued entitles the holder to purchase one share of Better Home & Finance Holding Company Class A common stock at an exercise price of $11.50 per share, subject to certain adjustments, at any time commencing 30 days after the consummation of the Business Combination (which for the avoidance of doubt was September 21, 2023). The Public Warrants are publicly traded and may be exercised on a cashless basis upon the occurrence of certain conditions. The Private Warrants are exercisable on a cashless basis and are not redeemable by the Company so long as they are held by the initial purchasers or their permitted transferees, subject to certain exceptions. If the Private Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Warrants will be redeemable by the Company and exercisable by the holders on the same basis as the Public Warrants. The Company evaluated the Public Warrants and Private Warrants and concluded that both meet the definition of a derivative and will be accounted for at fair value in accordance with ASC Topic 815-40, Derivatives and Hedging – Contracts in Entity’s Own Equity , as the Public Warrants and Private Warrants are not considered indexed to the Company's stock.
Income Taxes	Income taxes are calculated in accordance with ASC 740, Accounting for Income Taxes . An estimated annual effective tax rate is applied to year-to-date income (loss). At the end of each interim period, the estimated effective tax rate expected to be applicable for the full year is calculated. This method differs from that described in the Company’s income taxes policy footnote in the audited consolidated financial statements and related notes thereto for the
Revenue Recognition	The Company generates revenue from the following streams: 1) Mortgage platform revenue, net includes revenues generated from the Company's mortgage production process. See Note 4. The components of mortgage platform revenue, net are as follows: 1. Net gain (loss) on sale of loans—This represents the premium or discount the Company receives in excess of the loan principal amount and certain fees charged by loan purchasers upon sale of loans into the secondary market. Net gain (loss) on sale of loans includes unrealized changes in the fair value of LHFS which are recognized on a loan by loan basis as part of current period earnings until the loan is sold on the secondary market. The fair value of LHFS is measured based on observable market data. Also included within net gain (loss) on sale of loans is the day one recognition of the fair value of MSRs and any subsequent changes in the measurement of the fair value of the MSRs for loans sold servicing retained, including any gain or loss on subsequent sales of MSRs. 2. Integrated relationship revenue (loss)—Includes fees that the Company receives for originating loans on behalf of an integrated relationship partner which are recognized as revenue (loss) upon the integrated relationship partner’s funding of the loan. Some of the loans originated on behalf of the integrated relationship partner are purchased by the Company. Subsequent changes in fair value of loans purchased by the Company are included as part of current period earnings. These loans may be sold in the secondary market at the Company’s discretion for which any gain on sale is included in this account. For loans sold on the secondary market, the integrated relationship partner will receive a portion of the execution proceeds. A portion of the execution proceeds that is to be allocated to the integrated relationship partner is accrued as a reduction of integrated relationship revenue (loss) when the loan is initially purchased from the integrated relationship partner. 3. Changes in fair value of IRLCs and forward sale commitments—IRLCs include the fair value upon issuance with subsequent changes in the fair value recorded in each reporting period until the loan is sold on the secondary market. Fair value of forward sale commitments hedging IRLC and LHFS are measured based on quoted prices for similar assets. 2) Cash offer program revenue—The Company’s product offering includes a cash offer program (“Better Cash Offer”) where the Company works with a Buyer to identify and purchase a home directly from a property Seller. The Company will then subsequently sell the home to the Buyer. The Buyer may lease the home from the Company while the Buyer and Company go through the customary closing process to transfer ownership of the home to the Buyer. Arrangements where the Buyer leases the home from the Company are accounted for under ASC 842 while arrangements where the Buyer does not lease the home are accounted for under ASC 606. The Buyer does not directly or indirectly contract with the Seller. For arrangements under the Better Cash Offer program that do not involve a lease, upon closing on the sale of the home from the Seller to the Company, the Company holds legal title of the home. The Company is responsible for any obligations related to the home while it holds title and is the legal owner and such is considered the principal in the transaction. The Company holds in inventory any homes where the Buyer does not subsequently purchase from the Company as well as homes held while the Company is waiting to transfer the home to the Buyer. Inventory of homes are included within prepaid expenses and other assets on the condensed consolidated balance sheets. The Company recognizes revenue at the time of the closing of the home sale when title to and possession of the home are transferred to the Buyer. The amount of revenue recognized for each home sale is equal to the full sales price of the home. The contracts with the Buyers contain a single performance obligation that is satisfied upon the closing of the transaction and is typically completed in 1 to 90 days. The Company does not offer warranties for sold homes, and there are no continuing performance obligations following the transaction close date. Also included in Better Cash Offer program revenue is revenue from transactions where the Company purchases the home from the Seller and subsequently leases the home to the Buyer until the title is transferred to the Buyer which is accounted for under ASC 842 in line with the Company’s accounting policy on sales-type leases as described above. 3) Other platform revenue consists of revenue from the Company’s additional homeownership offerings which primarily consist of title insurance, settlement services, and other homeownership offerings. Title insurance, settlement services, and other homeownership offerings—Revenue from title insurance, settlement services, and other homeownership offerings is recognized based on ASU 2014-09, Revenue from Contracts with Customers (“ASC 606”). ASC 606 outlines a single comprehensive model in accounting for revenue arising from contracts with customers. The core principle, involving a five-step process, of the revenue model is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company offers title insurance as an agent and works with third-party providers that underwrite the title insurance policies. For title insurance, the Company recognizes revenue from fees upon the completion of the performance obligation which is when the mortgage transaction closes. For title insurance, the Company is the agent in the transactions as the Company does not control the ability to direct the fulfillment of the service, is not primarily responsible for fulfilling the performance of the service, and does not assume the risk in a claim against a policy. Settlement services revenue includes fees charged for services such as title search fees, wire fees, policy and document preparation, and other mortgage settlement services. The Company recognizes revenues from settlement services upon completion of the performance obligation which is when the mortgage transaction closes. The Company may use a third-party to fulfill these services, but the Company is considered the principal in the transaction as it directs the fulfillment of the services and ultimately bears the risk of nonperformance. As the Company is the principal, revenues from settlement services are presented on a gross basis. Performance obligations for title insurance and settlement services are typically completed 40 to 60 days after the commencement of the loan origination process. Payment for these services is typically settled in cash as part of closing costs to the borrower upon closing of the mortgage transaction. Other homeownership offerings consists primarily of real estate services. For real estate services, the Company generates revenues from fees related to real estate agent services, including cooperative brokerage fees from the Company’s network of third-party real estate agents, as well as brokerage fees earned when the Company provides it’s in-house real estate agents to assist customers in the purchase or sale of a home. The Company recognizes revenues from real estate services upon completion of the performance obligation which is when the mortgage transaction closes. Performance obligations for real estate services are typically completed 40 to 60 days after the commencement of the home search process. Payment for these services is typically settled in cash as part of closing costs to the borrower upon closing of the mortgage transaction.
Mortgage Platform, Cash Offer Program, and Other Platform Expenses	Mortgage platform expenses consist primarily of origination expenses, appraisal fees, processing expenses, underwriting, closing fees, servicing costs, and sales and operations personnel related expenses. Sales and operations personnel related expenses include compensation and related benefits, stock-based compensation, and allocated occupancy expenses and related overhead based on headcount. These expenses are expensed as incurred with the exception of stock-based compensation, which is recognized over the requisite service period.Better Cash Offer program expenses include the full cost of the home, including transaction closing costs and costs for maintaining the home before the legal title of the home is transferred to the Buyer. Better Cash Offer program expenses are recognized when title is transferred to the Buyer for arrangements recognized under ASC 606 and when the lease commences for arrangements recognized under ASC 842.Other platform expenses relate to other non-mortgage homeownership activities, including settlement service expenses, lead generation, and personnel related costs. Settlement service expenses consist of fees for transactional services performed by third-party providers for borrowers while lead generation expenses consist of fees for services related to real estate agents. Personnel related expenses include compensation and related benefits, stock-based compensation, and allocated occupancy expenses and related overhead based on headcount. Other platform expenses are expensed as incurred with the exception of stock-based compensation, which is recognized over the requisite service period.
General and Administrative Expenses	General and administrative expenses include personnel related expenses, including stock-based compensation and benefits for executive, finance, accounting, legal, and other administrative personnel. In addition, general and administrative expenses include external legal, tax and accounting services, and allocated occupancy expenses and related overhead based on headcount. General and administrative expenses are expensed as incurred with the exception of stock-based compensation, which is recognized over the requisite service period.
Marketing and Advertising Expenses	Marketing and advertising expenses consist of customer acquisition expenses, brand costs, paid advertising, and personnel related costs for brand teams. For customer acquisition expenses, the Company primarily generates loan origination leads through third-party financial service websites for which they incur “pay-per-click” expenses. A majority of the Company’s marketing and advertising expenses are incurred from leads purchased from these third-party financial service websites. Personnel related expenses include compensation and related benefits, stock-based compensation, and allocated occupancy expenses and related overhead based on headcount. Marketing and advertising expenses are expensed as incurred with the exception of stock-based compensation, which is recognized over the requisite service period.
Technology and Product Development Expenses	Technology and product development expenses consist of employee compensation, amortization of capitalized internal-use software costs related to the Company’s technology platform, and expenses related to vendors engaged in product management, design, development, and testing of the Company’s websites and products. Employee compensation consists of stock-based compensation and benefits related to the Company’s technology team, product and creative team, and engineering team. Technology and product development expenses also include allocated occupancy expenses and related overhead based on headcount. Technology and product development expenses are expensed as incurred with the exception of stock-based compensation, which is recognized over the requisite service period.
Segments	The Company has one reportable segment. The Company’s chief operating decision maker, the Chief Executive Officer, reviews financial information presented on a company-wide basis for purposes of allocating resources and evaluating financial performance.
Recently Adopted Accounting Standards	In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . In addition, in January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope , which clarified the scope and application of the original guidance. Subject to meeting certain criteria, the new guidance provides optional expedients and exceptions to applying contract modification accounting under existing U.S. GAAP, to address the expected phase out of the London Inter-bank Offered Rate (or “LIBOR”) by September 30, 2023. This guidance is effective upon issuance and allows application to contract changes as early as January 1, 2020. The guidance is effective for all companies as of March 12, 2020 and can generally be applied through December 31, 2022. In December 2022, FASB issued ASU 2022-06, Reference Rate Reform ("Topic 848"): Deferral of the Sunset Date of Topic 848 , because the current relief in Topic 848 may not cover a period of time during which a significant number of modifications may take place, the amendments in this Update defer the sunset date of Topic 848 from December 31, 2022 to December 31, 2024, after which entities will no longer be permitted to apply the relief in Topic 848. The adoption of the new guidance did not have a material impact on the condensed consolidated financial statements.
