Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in conformity with the instructions of the Securities and Exchange Commission (SEC) to Form 10-Q and SEC Regulation S-X, Article 10, Rule 10-01 for interim financial statements. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America (GAAP) for complete financial statements. In our opinion, the accompanying unaudited consolidated financial statements contain all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation. The results of operations and other data for the three and nine months ended September 30, 2024 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2024. The unaudited consolidated financial statements presented herein should be read in conjunction with the audited consolidated financial statements and related notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2023. Amounts may not add in certain tables due to rounding. Change in Presentation Effective June 30, 2024, in our consolidated balance sheets we now present Contingent loan repurchase asset and Contingent loan repurchase liability as separate line items (previously reported in Other assets and Other liabilities, respectively). In connection with the Ginnie Mae early buyout program, our servicing agreements provide that we have the right, but not the obligation, to repurchase previously transferred mortgage loans under certain conditions, including the mortgage loans becoming unpaid for more than three consecutive months. Once these conditions are met, we have effectively regained control over the mortgage loans, and under GAAP, must re-recognize the loans on our consolidated balance sheets and establish a corresponding repurchase liability. The separate presentation of such assets and offsetting liabilities on the face of the balance sheet provides increased transparency compared to a presentation within Other assets and Other liabilities. The consolidated balance sheet as of December 31, 2023 has been recast to conform to the current period presentation. This presentation change had no impact on total assets or total liabilities in our consolidated balance sheets, no impact on the consolidated statements of cash flows, nor any other financial statements.
Use of Estimates and Assumptions	Use of Estimates and Assumptions The preparation of financial statements in conformity with GAAP requires that management 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates and assumptions include, but are not limited to, those that relate to fair value measurements, income taxes and the provision for losses that may arise from contingencies including litigation proceedings. In developing estimates and assumptions, management uses all available information; however, actual results could materially differ from those estimates and assumptions.
Recently Adopted Accounting Standards And Accounting Standards Issued but Not Yet Adopted	Recently Adopted Accounting Standards Leases (ASC 842) Common Control Arrangements (ASU 2023-01) Prior to the issuance of this ASU, ASC 842 required all lessees to amortize leasehold improvements over the shorter of their useful life or the remaining term of the lease. For leases between entities under common control, the amendment in this ASU requires amortization of leasehold improvements over the useful life of those assets to the common control group, regardless of the lease term. When the lessee no longer controls the use of the asset underlying the common control lease, the leasehold improvements are accounted for as a transfer between entities under common control whereby the lessee records a distribution to the common control lessor through an adjustment to equity. Our adoption of this standard on January 1, 2024 did not have a material impact on our unaudited consolidated financial statements. Accounting Standards Issued but Not Yet Adopted Business Combinations - Joint Venture Formations (ASC 805-60): Recognition and Initial Measurement (ASU 2023-05) The amendments in this ASU require a joint venture to apply a new basis of accounting upon formation for the initial contribution of nonmonetary and monetary assets, initially measured at fair value (with exceptions to fair value measurement consistent with business combinations guidance). This ASU does not amend the definition of a joint venture, the accounting by an equity method investor for its investment in a joint venture, or the accounting by a joint venture for contributions received after its formation. The amendments in this ASU are effective prospectively for all joint venture formations with a formation date on or after January 1, 2025, with early adoption permitted. A joint venture formed prior to the adoption date may elect to apply the new guidance retrospectively back to the original formation date. We do not anticipate that the adoption of this standard will have a material impact on our consolidated financial statements. Segment Reporting (ASC 280) Improvements to Reportable Segment Disclosures (ASU 2023-07) The amendments in this ASU were issued to improve annual and interim reportable segment disclosure requirements, primarily through enhanced disclosures about expenses that are significant to the segment, regularly provided to or easily computed from information regularly provided to the chief operating decision maker (CODM), and included in the reported measure of segment profit or loss. This ASU also requires disclosure of the title and position of the individual or the name of the group identified as the CODM in the consolidated financial statements, as well as how the CODM uses each reported measure of segment profit or loss to assess performance and allocate resources to the segment. The ASU allows the disclosure of additional optional measures of a segment’s profit or loss for each reportable segment if used by the CODM, subject to additional segment disclosures and the SEC’s non-GAAP financial measures requirements. The amended disclosures in this ASU are effective in the 2024 annual period and in 2025 for interim periods, and shall be applied retrospectively to all prior periods presented in the financial statements. Upon transition, the segment expense categories and amounts disclosed in the prior periods should be based on the significant segment expense categories identified and disclosed in the period of adoption. Income Taxes (ASC 740) Improvements to Income Tax Disclosures (ASU 2023-09) The amendments in this ASU require disaggregated information about a reporting entity’s effective tax rate reconciliation, including a tabular rate reconciliation for specified categories and additional information for reconciling items that meet a quantitative threshold. The ASU also requires additional disaggregated information on income taxes paid to an individual jurisdiction equal to or greater than 5% of total income taxes paid. The amended disclosures are effective in the 2025 annual period and in 2026 for interim periods, and shall be applied on a prospective basis with the option to apply the standard retrospectively.
