Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements presented herein are at September 30, 2024 and December 31, 2023, and for the three and nine months ended September 30, 2024 and 2023. These interim unaudited consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC") and U.S. generally accepted accounting principles ("GAAP"). Certain disclosures typically included in our annual financial statements may be condensed or omitted from these interim financial statements, as permitted. Management believes that the disclosures included in these interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2023. In the opinion of management, all normal and recurring adjustments have been made to present fairly the financial condition of the Company at September 30, 2024 and results of operations for all periods presented. The results of operations for the three and nine months ended September 30, 2024 should not be construed as indicative of the results to be expected for the full year. In the first quarter of 2024, we updated the names of our Residential loans to Residential consumer loans and our Business purpose loans to Residential investor loans. There were no changes to the classifications of account balances as a result of these updates. All prior period references in this document were conformed to this presentation. In the second quarter of 2024, we combined the presentation of Short-term and Long-term debt within Debt obligations, net and Goodwill and Intangible assets within Other assets on the consolidated balance sheets and consolidated statements of income, as applicable. There was no impact to the consolidated financial statements as a result of this change and all prior periods in this document were conformed to this presentation. Principles of Consolidation The consolidated financial statements include the accounts of the entities where the Company has a controlling financial interest. The method for determining whether a controlling financial interest exists varies depending on whether the entity is a VIE. The Company has a controlling financial interest in and consolidates a VIE when the firm has a variable interest or interests that provide it with (i) the power to direct the activities of the VIE that most significantly impact the VIE's economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits for the VIE that could potentially be significant to the VIE. See Note 15 for further information about VIEs. For entities that are not VIEs, we have a controlling financial interest in entities where we hold a majority of the voting rights. We use the equity method to account for our interest in entities in which we do not have a controlling financial interest, but over which we have significant influence. For financial reporting purposes, we consolidate the assets and liabilities of certain entities formed in connection with the securitization of our loans and home equity investments ("HEI"), which we have determined to be VIEs and in which we have a controlling financial interest. The underlying loans owned at the consolidated securitization entities are shown under Residential consumer loans and Residential investor loans on our consolidated balance sheets. In our consolidated statements of income, we record interest income on the loans owned at these entities and interest expense on the ABS issued by these entities as well as fair value changes, other income and expenses associated with these entities' activities. The asset-backed securities (“ABS”) issued to third parties by these entities are shown under ABS issued. See Note 16 for further discussion on ABS issued. The underlying HEI at the consolidated HEI securitization entities are shown under Home equity investments on our consolidated balance sheets and the associated fair value changes and interest expense associated with ABS issued are shown under HEI income, net on our consolidated statements of income (loss). See Note 10 for further discussion on HEI. We also consolidate two partnerships ("Servicing Investment" entities) through which we have invested in servicing-related assets. We maintain an 80% ownership interest in each entity and have determined that we are the primary beneficiary of these partnerships. See Note 15 for further discussion on Principles of consolidation. Use of Estimates The preparation of financial statements requires us to make a number of significant estimates. These include estimates of fair value of certain assets and liabilities, amounts and timing of credit losses, prepayment rates, valuation allowances, and other estimates that affect the reported amounts of certain assets and liabilities as of the date of the consolidated financial statements and the reported amounts of certain revenues and expenses during the reported periods. It is likely that changes in these estimates (e.g., valuation changes due to supply and demand, credit performance, prepayments, interest rates, or other reasons) will occur in the near term. Our estimates are inherently subjective in nature and actual results could differ from our estimates and the differences could be material.
