Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business and Basis of Presentation	1. Nature of Business and Basis of Presentation Nature of Business Mr. Cooper Group Inc., collectively with its consolidated subsidiaries, (“Mr. Cooper,” the “Company,” “we,” “us” or “our”) provides servicing, origination and transaction-based services related to single family residences throughout the United States with operations under its primary brands: Mr. Cooper® and Xome®. Mr. Cooper is one of the largest home loan originators and servicers in the country focused on delivering a variety of servicing and lending products, services and technologies. Xome provides technology and data enhanced solutions to homebuyers, home sellers, real estate agents and mortgage companies. The Company’s corporate website is located at www.mrcoopergroup.com . The Company has provided a glossary of terms, which defines certain industry-specific and other terms that are used herein, in Item 2, Management’s Discussion and Analysis of Financial Condition and Results of Operations , of this Form 10-Q. On March 12, 2021, the Company entered into a Stock Purchase Agreement with Blend Labs, Inc. (“Blend Labs”), a Delaware corporation, pursuant to which Blend Labs will acquire the title business of the Company for a purchase price of approximately $500, consisting of approximately $450 in cash, subject to certain adjustments specified therein, and a retained interest of 9.9% for the Company (the “Title Transaction”). The Title Transaction was completed on June 30, 2021, with consideration received on July 1, 2021. A receivable for consideration was recorded in other assets in the Company’s condensed consolidated balance sheets as of June 30, 2021. Pursuant to the Stock Purchase Agreement, all cash generated, subject to certain adjustments, between March 13, 2021 and the closing date of the Title Transaction, were held for the benefit of Blend Labs. A $487 gain on the Title Transaction was recorded in the second quarter of 2021 upon closing of the Title Transaction, which was included in other income, net within the condensed consolidated statements of operations. In addition, the Company recorded total transaction costs of $2 and $5 for the three and six months ended June 30, 2021, respectively . The results of the title business were previously reported under the Xome segment. The carrying amounts of assets and liabilities associated with the title business were not material to the condensed consolidated balance sheets as of December 31, 2020. On July 1, 2021, the Company entered into a definitive agreement for the sale of its reverse servicing portfolio, operating under the Champion Mortgage brand (“Champion”), to Mortgage Assets Management, LLC and its affiliates (“MAM”). The reverse servicing operation was previously reported in the Company’s Servicing segment. The Company determined t he sale of the reverse servicing portfolio qualified for reporting as discontinued operations as of June 30, 2021. As a result, t he reverse servicing operation is presented as discontinued operations in the Company’s condensed consolidated statements of operations and the assets and liabilities of the reverse servicing operation are presented as discontinued operations in the Company’s condensed consolidated balance sheets for all periods presented. Unless otherwise indicated, information in this report relates to the Company’s continuing operations. Refer to Note 2, Discontinued Operations for further details. Basis of Presentation The interim condensed consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission. Accordingly, the financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Reports on Form 10-K for the year ended December 31, 2020. The interim condensed consolidated financial statements are unaudited; however, in the opinion of management, all adjustments, consisting of normal recurring items, considered necessary for a fair presentation of the results of the interim periods have been included. Dollar amounts are reported in millions, except per share data and other key metrics, unless otherwise noted. Basis of Consolidation The condensed consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries, other entities in which the Company has a controlling financial interest and those variable interest entities (“VIE”) where the Company’s wholly-owned subsidiaries are the primary beneficiaries. Assets and liabilities of VIEs and their respective results of operations are consolidated from the date that the Company became the primary beneficiary through the date the Company ceases to be the primary beneficiary. The Company applies the equity method of accounting to investments where it is able to exercise significant influence, but not control, over the policies and procedures of the entity and owns less than 50% of the voting interests. Investments in certain companies over which the Company does not exert significant influence are accounted for as cost method investments. Intercompany balances and transactions on consolidated entities have been eliminated. Use of Estimates The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from these estimates due to factors such as adverse changes in the economy, changes in interest rates, secondary market pricing for loans held for sale and derivatives, strength of underwriting and servicing practices, changes in prepayment assumptions, declines in home prices or discrete events adversely affecting specific borrowers, uncertainties in the economy from the COVID-19 pandemic, and such differences could be material. In the second quarter of 2021, the Company refined its estimation process for determining the fair value of forward MSRs by incorporating an estimate of future cash flows from existing loans that are expected to be recaptured, which is consistent with recent pricing observed from market participants. This refinement did not result in a significant change to the overall valuation of the Company’s mortgage servicing rights (“MSRs”) portfolio . See Note 3, Mortgage Servicing Rights and Related Liabilities and Note 13, Fair Value Measurements for further discussion. There were no other changes to the Company’s use of estimates for the period ended June 30, 2021 .

Discontinued Operations and Disposal Groups [Abstract]
Disposal Groups, Including Discontinued Operations, Disclosure	2. Discontinued Operations On July 1, 2021, the Company entered into a definitive agreement for the sale of its reverse servicing portfolio, operating under Champion, to MAM. Upon close of the transaction, which is subject to regulatory approvals and other closing conditions, MAM will assume Champion’s reverse portfolio and related operations. The sale is expected to close prior to the end of 2021. The carrying amounts of assets and liabilities associated with the reverse servicing operation are reported under the Servicing segment. The Company determined reverse servicing operations met the criteria for classification as held for sale as of June 30, 2021 and represents a strategic shift in the Company’s operations. Therefore, the sale of the reverse servicing portfolio qualifies for reporting as discontinued operations, and the assets and liabilities of the reverse servicing portfolio are reported as discontinued operations in the condensed consolidated balance sheets and related results of operations are reported as discontinued operations in the condensed consolidated statements of operations for all periods presented. As part of the transaction, the Company entered into a servicing agreement with MAM, under which the Company will be compensated for continuing to service these reverse loans through the date that the loans are transferred out of Company’s servicing system, which will be the date of close. In addition, the Company will retain certain loans related to the reverse servicing portfolio, primarily related to previously liquidated loans, with total assets of $112 and total liabilities of $88 as of June 30, 2021. The following table sets forth the assets and liabilities included in discontinued operations: June 30, 2021 December 31, 2020 Carrying amounts of assets of discontinued operations Restricted cash $ 77 $ 83 Reverse mortgage interests, net 4,910 5,253 Other 9 11 Loss recognized on classification as discontinued operations (61) — Total assets of discontinues operations $ 4,935 $ 5,347 Carrying amounts of liabilities of discontinued operations Advances and warehouse facilities, net $ 525 $ 505 Payables and other liabilities 224 233 Mortgage servicing liabilities 42 41 Other nonrecourse debt, net 3,999 4,424 Total liabilities of discontinued operations $ 4,790 $ 5,203 The following table sets forth the condensed consolidated statements of operations data for discontinued operations: Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 Revenue - service related, net $ 1 $ 12 $ 9 $ 26 Salaries, wages and benefits expense (8) (10) (16) (22) General and administrative expense 71 (10) 64 (18) Interest income 43 53 87 96 Interest expense (30) (50) (64) (103) Loss on classification as discontinued operations (61) — (61) — Income (loss) from discontinued operations before income tax expense (benefit) 16 (5) 19 (21) Less: Income tax expense (benefit) 4 (1) 5 (5) Net income (loss) from discontinued operations $ 12 $ (4) $ 14 $ (16)

Mortgage Servicing Rights and Related Liabilities	3. Mortgage Servicing Rights and Related Liabilities The following table sets forth the carrying value of the Company’s mortgage servicing rights (“MSRs”) and the related liabilities. In estimating the fair value of all mortgage servicing rights and related liabilities, the impact of the current environment was considered in the determination of key assumptions. MSRs and Related Liabilities June 30, 2021 December 31, 2020 Forward MSRs - fair value $ 3,307 $ 2,703 Excess spread financing - fair value $ 867 $ 934 Mortgage servicing rights financing - fair value 21 33 MSR related liabilities - nonrecourse at fair value $ 888 $ 967 Forward Mortgage Servicing Rights The following table sets forth the activities of forward MSRs: Six Months Ended June 30, Forward MSRs - Fair Value 2021 2020 Fair value - beginning of period $ 2,703 $ 3,496 Additions: Servicing retained from mortgage loans sold 554 249 Purchases of servicing rights 218 24 Dispositions: Sales of servicing assets (12) — Changes in fair value: Changes in valuation inputs or assumptions used in the valuation model 270 (717) Changes in valuation due to amortization (460) (338) Other changes 34 43 Fair value - end of period $ 3,307 $ 2,757 During the six months ended June 30, 2021 and 2020, the Company sold $1,076 and $71 in unpaid principal balance (“UPB”) of forward MSRs, of which $1,008 and none were retained by the Company as subservicer, respectively. MSRs measured at fair value are segregated between investor type into agency and non-agency pools (referred to herein as “investor pools”) based upon contractual servicing agreements with investors at the respective balance sheet date to evaluate the MSR portfolio and fair value of the portfolio. Agency investors primarily consist of government sponsored enterprises (“GSE”), such as the Federal National Mortgage Association (“Fannie Mae” or “FNMA”) and the Federal Home Loan Mortgage Corp (“Freddie Mac” or “FHLMC”), and the Government National Mortgage Association (“Ginnie Mae” or “GNMA”). Non-agency investors consist of investors in private-label securitizations. The following table provides a breakdown of UPB and fair value for the Company’s forward MSRs: June 30, 2021 December 31, 2020 Forward MSRs - UPB and Fair Value Breakdown UPB Fair Value UPB Fair Value Investor Pools Agency $ 248,799 $ 2,955 $ 227,136 $ 2,305 Non-agency 38,656 352 44,053 398 Total $ 287,455 $ 3,307 $ 271,189 $ 2,703 In the second quarter of 2021, the Company refined its estimate of the fair value of forward MSRs by incorporating an estimate of future cash flows from existing loans that are expected to be recaptured. The estimate of future cash flows related to recapture is consistent with recent pricing observed from various market participants, including the Company’s independent, third-party valuation firms. As a result of considering the recapture rate, the Company adjusted its discount rate assumption in order to ensure that the fair value of forward MSRs remains consistent with current market participant pricing and was also corroborated with valuations provided by independent, third parties. The net impact on the overall forward MSRs fair value was not significant during the three and six months ended June 30, 2021. Refer to Note 13, Fair Value Measurements , for further discussion on key weighted-average inputs and assumptions used in estimating the fair value of forward MSRs. The following table shows the hypothetical effect on the fair value of the Company’s forward MSRs when applying certain unfavorable variations of key assumptions to these assets for the dates indicated: Discount Rate Total Prepayment Speeds Cost to Service per Loan Forward MSRs - Hypothetical Sensitivities 100 bps Adverse Change 200 bps Adverse Change 10% Adverse Change 20% Adverse Change 10% Adverse Change 20% Adverse Change June 30, 2021 Mortgage servicing rights $ (112) $ (216) $ (139) $ (268) $ (43) $ (87) December 31, 2020 Mortgage servicing rights $ (100) $ (192) $ (181) $ (347) $ (45) $ (89) These hypothetical sensitivities should be evaluated with care. The effect on fair value of an adverse change in assumptions generally cannot be determined because the relationship of the change in assumptions to the fair value may not be linear. Additionally, the impact of a variation in a particular assumption on the fair value is calculated while holding other assumptions constant. In reality, changes in one factor may lead to changes in other factors, which could impact the above hypothetical effects. Excess Spread Financing - Fair Value The Company had excess spread financing liability of $867 and $934 as of June 30, 2021 and December 31, 2020, respectively. Refer to Note 13, Fair Value Measurements , for key weighted-average inputs and assumptions used in the valuation of excess spread financing. The following table shows the hypothetical effect on the Company’s excess spread financing fair value when applying certain unfavorable variations of key assumptions to these liabilities for the dates indicated: Discount Rate Prepayment Speeds Excess Spread Financing - Hypothetical Sensitivities 100 bps Adverse Change 200 bps Adverse Change 10% Adverse Change 20% Adverse Change June 30, 2021 Excess spread financing $ 30 $ 61 $ 34 $ 70 December 31, 2020 Excess spread financing $ 30 $ 62 $ 41 $ 84 These hypothetical sensitivities should be evaluated with care. The effect on fair value of an adverse change in assumptions generally cannot be determined because the relationship of the change in assumptions to the fair value may not be linear. Additionally, the impact of a variation in a particular assumption on the fair value is calculated while holding other assumptions constant. In reality, changes in one factor may lead to changes in other factors, which could impact the above hypothetical effects. Also, a positive change in the above assumptions would not necessarily correlate with the corresponding decrease in the net carrying amount of the excess spread financing. Excess spread financing’s cash flow assumptions that are utilized in determining fair value are based on the related cash flow assumptions used in the financed MSRs. Any fair value change recognized in the financed MSRs attributable to related cash flows assumptions would inherently have an inverse impact on the carrying amount of the related excess spread financing. Mortgage Servicing Rights Financing - Fair Value The Company had MSR financing liability of $21 and $33 as of June 30, 2021 and December 31, 2020, respectively. Refer to Note 13, Fair Value Measurements , for key weighted-average inputs and assumptions used in the valuation of the MSR financing liability. Servicing Segment Revenues The following table sets forth the items comprising total revenues for the Servicing segment: Three Months Ended June 30, Six Months Ended June 30, Total Revenues - Servicing 2021 2020 2021 2020 Contractually specified servicing fees (1) $ 275 $ 285 $ 551 $ 582 Other service-related income (1) 214 62 359 111 Incentive and modification income (1) 14 8 28 18 Late fees (1) 16 20 34 47 Mark-to-market adjustments (2) (180) (261) 174 (644) Counterparty revenue share (3) (76) (88) (159) (164) Amortization, net of accretion (4) (158) (107) (314) (191) Total revenues - Servicing $ 105 $ (81) $ 673 $ (241) (1) The Company recognizes revenue on an earned basis for services performed. Amounts include subservicing related revenues. (2) Mark-to-market (“MTM”) adjustments include fair value adjustments on MSR, excess spread financing and MSR financing liabilities. The amount of MSR MTM includes the impact of negative modeled cash flows which have been transferred to reserves on advances and other receivables. The negative modeled cash flows relate to advances and other receivables associated with inactive and liquidated loans that are no longer part of the MSR portfolio. The impact of negative modeled cash flows was $8 and $3 for the three months ended June 30, 2021 and 2020 and $20 and $13 for the six months ended June 30, 2021 and 2020, respectively. (3) Counterparty revenue share represents the excess servicing fee that the Company pays to the counterparties under the excess spread financing arrangements and the payments made associated with MSR financing arrangements. (4) Amortization is net of excess spread a ccretion of $70 and $79 during the three months ended June 30, 2021 and 2020, respectively. For the six months ended June 30, 2021 and 2020, amortization is net of excess spread accretion of $146 and $147, respectively.

Receivables [Abstract]
Loans Subject to Repurchase from Ginnie Mae	6. Loans Subject to Repurchase from Ginnie Mae Forward loans are sold to Ginnie Mae in conjunction with the issuance of mortgage backed securities. The Company, as the issuer of the mortgage backed securities, has the unilateral right to repurchase any individual loan in a Ginnie Mae securitization pool if that loan meets certain criteria, including payments not being received from borrowers for greater than 90 days. Once the Company has the unilateral right to repurchase a delinquent loan, it has effectively regained control over the loan and recognizes these rights to the loan on its condensed consolidated balance sheets and establishes a corresponding repur chase liability regardless of the Company’s intention to repurchase the loan. The Company had loans subject to repurchase from Ginnie Mae of $4,057 and $6,159 as of June 30, 2021 and December 31, 2020, respectively, which are included in both other assets and payables and other liabilities in the condensed consolidated balance sheets .

Variable Interest Entities and Securitizations [Abstract]
Securitizations and Financings	10. Securitizations and Financings Variable Interest Entities In the normal course of business, the Company enters into various types of on- and off-balance sheet transactions with special purpose entities (“SPEs”) determined to be VIEs, which primarily consist of securitization trusts established for a limited purpose. Generally, these SPEs are formed for the purpose of securitization transactions in which the Company transfers assets to an SPE, which then issues to investors various forms of debt obligations supported by those assets. The Company has determined that the SPEs created in connection with certain advance facilities trusts should be consolidated as the Company is the primary beneficiary of each of these entities. A summary of the assets and liabilities of the Company’s transactions with VIEs included in the Company’s condensed consolidated balance sheets is presented below: June 30, 2021 December 31, 2020 Consolidated Transactions with VIEs Transfers Transfers Assets Restricted cash $ 44 $ 47 Advances and other receivables, net 387 441 Total assets $ 431 $ 488 Liabilities Advance facilities (1) $ 310 $ 358 Payables and other liabilities — 1 Total liabilities $ 310 $ 359 (1) Refer to advance facilities in Note 9, Indebtedness , for additional information. The following table shows a summary of the outstanding collateral and certificate balances for securitization trusts for which the Company was the transferor, including any retained beneficial interests and MSRs, that were not consolidated by the Company: Unconsolidated Securitization Trusts June 30, 2021 December 31, 2020 Total collateral balances - UPB $ 1,230 $ 1,326 Total certificate balances $ 1,229 $ 1,329 The Company has not retained any variable interests in the unconsolidated securitization trusts that were outstanding as of June 30, 2021 and December 31, 2020. Therefore, it does not have a significant maximum exposure to loss related to these unconsolidated VIEs. A summary of mortgage loans transferred by the Company to unconsolidated securitization trusts that are 60 days or more past due are presented below: Principal Amount of Transferred Loans 60 Days or More Past Due June 30, 2021 December 31, 2020 Unconsolidated securitization trusts $ 141 $ 154

Earnings Per Share [Abstract]
Earnings Per Share	11. Earnings Per Share The Company computes earnings per share using the two-class method, which is an earnings allocation formula that determines earnings per share for common stock and any participating securities according to dividends declared (whether paid or unpaid) and participation rights in undistributed earnings. The Series A Preferred Stock is considered participating securities because it has dividend rights determined on an as-converted basis in the event of Company’s declaration of a dividend or distribution for common shares. On March 26, 2021, the Company repurchased 3,700 thousand shares of its common stock from affiliates of Kohlberg Kravis Roberts & Co. L.P., a related party of the Company, for a total cost of $119 or $32.25 per share.

Income Taxes	12. Income Taxes For the three and six months ended June 30, 2021, the effective tax rate was 24.8% and 23.7%, respectively, which differed from the statutory federal rate of 21% primarily due to state income taxes and nondeductible executive compensation. The effective tax rate decreased during the six months ended June 30, 2021 compared to the same period in 2020, primarily due to quarterly discrete tax items related to the completion of the Title Transaction and excess tax benefit from stock-based compensation. For the three and six months ended June 30, 2020, the effective tax rate was 33.0% and 24.2%, respectively, which differed from the statutory federal rate of 21% primarily due to state income taxes and nondeductible executive compensation.

Fair Value Disclosures [Abstract]
Fair Value Measurements	13. Fair Value Measurements Fair value is a market-based measurement, not an entity-specific measurement, and should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, a three-tiered fair value hierarchy has been established based on the level of observable inputs used in the measurement of fair value (e.g., Level 1 representing quoted prices for identical assets or liabilities in an active market; Level 2 representing values using observable inputs other than quoted prices included within Level 1; and Level 3 representing estimated values based on significant unobservable inputs). There have been no significant changes to the valuation techniques and inputs used by the Company in estimating fair values of Level 2 and Level 3 assets and liabilities as disclosed in the Company’s Annual Reports on Form 10-K for the year ended December 31, 2020, with the exception of the following: Mortgage Servicing Rights – Fair Value (Level 3) – The Company estimates the fair value of its forward MSRs on a recurring basis using a process that combines the use of a discounted cash flow model and analysis of current market data to arrive at an estimate of fair value. The cash flow assumptions and prepayment assumptions used in the model are based on a discounted cash flow model which incorporates prepayment speeds, delinquencies, discount rate, ancillary revenues, float earnings and other assumptions (including costs to service, recapture rates and forbearance rates), with the key assumptions being mortgage prepayment speeds, discount rates, and cost to service. In the second quarter of 2021, the Company refined its estimate of the fair value of forward MSRs by incorporating an estimate of future cash flows from loans that are expected to be recaptured. The estimate of future cash flows related to recapture is consistent with recent pricing observed from various market participants, including the Company’s independent third-party valuation firms As a result of considering the recapture rate, the Company adjusted its discount rate assumption in order to ensure that the fair value of forward MSRs remains consistent with current market participant pricing and is reflective of an exit price. The estimated fair value was also corroborated with valuations provided by independent third parties. The net impact on the overall forward MSRs fair value was not significant during the three and six months ended June 30, 2021. These assumptions are generated and applied based on collateral stratifications including product type, remittance type, geography, delinquency and coupon dispersion. These assumptions require the use of judgment by the Company and can have a significant impact on the fair value of the MSRs. Quarterly, management obtains third-party valuations to assess the reasonableness of the fair value calculations provided by the internal cash flow model. Because of the nature of the valuation inputs, the Company classifies these valuations as Level 3 in the fair value disclosures. See Note 3, Mortgage Servicing Rights and Related Liabilities , for more information. The following tables present the estimated carrying amount and fair value of the Company’s financial instruments and other assets and liabilities measured at fair value on a recurring basis: June 30, 2021 Recurring Fair Value Measurements Fair Value - Recurring Basis Total Fair Value Level 1 Level 2 Level 3 Assets Mortgage loans held for sale $ 6,961 $ — $ 6,961 $ — Forward mortgage servicing rights 3,307 — — 3,307 Derivative financial instruments IRLCs 204 — — 204 LPCs 10 — — 10 Forward MBS trades 27 — 27 — Liabilities Derivative financial instruments LPCs 1 — — 1 Forward MBS trades 25 — 25 — Mortgage servicing rights financing 21 — — 21 Excess spread financing 867 — — 867 December 31, 2020 Recurring Fair Value Measurements Fair Value - Recurring Basis Total Fair Value Level 1 Level 2 Level 3 Assets Mortgage loans held for sale $ 5,720 $ — $ 5,720 $ — Forward mortgage servicing rights 2,703 — — 2,703 Derivative financial instruments IRLCs 414 — — 414 LPCs 38 — — 38 Forward MBS trades 37 — 37 — Liabilities Derivative financial instruments LPCs 1 — — 1 Forward MBS trades 156 — 156 — Mortgage servicing rights financing 33 — — 33 Excess spread financing 934 — — 934 The tables below present a reconciliation for all of the Company’s Level 3 assets and liabilities measured at fair value on a recurring basis: Six Months Ended June 30, 2021 Assets Liabilities Fair Value - Level 3 Assets and Liabilities Forward mortgage servicing rights IRLCs LPCs Excess spread financing Mortgage servicing rights financing Balance - beginning of period $ 2,703 $ 414 $ 38 $ 934 $ 33 Changes in fair value included in earnings (190) (210) (28) 14 (12) Other changes 34 — — — — Purchases, issuances, sales, repayments and settlements Purchases 218 — — — — Issuances 554 — — — — Sales (12) — — — — Settlements and repayments — — — (81) — Balance - end of period $ 3,307 $ 204 $ 10 $ 867 $ 21 Six Months Ended June 30, 2020 Assets Liabilities Fair Value - Level 3 Assets and Liabilities Forward mortgage servicing rights IRLCs Excess spread financing Mortgage servicing rights financing Balance - beginning of period $ 3,496 $ 135 $ 1,311 $ 37 Changes in fair value included in earnings (1,055) 235 (101) 12 Other changes 43 — — — Purchases, issuances, sales, repayments and settlements Purchases 24 — — — Issuances 249 — 24 — Settlements and repayments — — (110) — Balance - end of period $ 2,757 $ 370 $ 1,124 $ 49 No transfers were made in or out of Level 3 fair value assets and liabilities for the Company during the six months ended June 30, 2021 and 2020.

Mortgage Banking [Abstract]
Capital Requirements	14. Capital Requirements Certain of the Company’s secondary market investors require minimum net worth (“capital”) requirements, as specified in the respective selling and servicing agreements. In addition, these investors may require capital ratios in excess of the stated requirements to approve large servicing transfers. To the extent that these requirements are not met, the Company’s secondary market investors may utilize a range of remedies ranging from sanctions, suspension or ultimately termination of the Company’s selling and servicing agreements, which would prohibit the Company from further originating or securitizing these specific types of mortgage loans or being an approved servicer. The Company’s various capital requirements related to its outstanding selling and servicing agreements are measured based on the Company’s operating subsidiary, Nationstar Mortgage LLC. As of June 30, 2021, the Company was in compliance with its selling and servicing capital requirements.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	15. Commitments and Contingencies Litigation and Regulatory The Company and its subsidiaries are routinely and currently involved in a significant number of legal proceedings, including, but not limited to, judicial, arbitration, regulatory and governmental proceedings related to matters that arise in connection with the conduct of the Company’s business. The legal proceedings are at varying stages of adjudication, arbitration or investigation and are generally based on alleged violations of consumer protection, securities, employment, contract, tort, common law fraud and other numerous laws, including, without limitation, the Equal Credit Opportunity Act, Fair Debt Collection Practices Act, Fair Credit Reporting Act, Real Estate Settlement Procedures Act, National Housing Act, Homeowners Protection Act, Service Member’s Civil Relief Act, Telephone Consumer Protection Act, Truth in Lending Act, Financial Institutions Reform, Recovery, and Enforcement Act of 1989, unfair, deceptive or abusive acts or practices in violation of the Dodd-Frank Act, the Securities Act of 1933, the Securities Exchange Act of 1934, the Home Mortgage Disclosure Act, Title 11 of the United States Code (aka the “Bankruptcy Code”), False Claims Act and Making Home Affordable loan modification programs. In addition, along with others in its industry, the Company is subject to repurchase and indemnification claims and may continue to receive claims in the future, regarding alleged breaches of representations and warranties relating to the sale of mortgage loans, the placement of mortgage loans into securitization trusts or the servicing of mortgage loans securitizations. The Company is also subject to legal actions or proceedings related to loss sharing and indemnification provisions of its various acquisitions. Certain of the pending or threatened legal proceedings include claims for substantial compensatory, punitive and/ or statutory damages or claims for an indeterminate amount of damages. The Company operates within highly regulated industries on a federal, state and local level. In the normal and ordinary course of its business, the Company is routinely subject to extensive examinations, investigations, subpoenas, inquiries and reviews by various federal, state and local governmental, regulatory and enforcement agencies, including the Consumer Financial Protection Bureau, the Securities and Exchange Commission, the Department of Justice, the Office of the Special Inspector General for the Troubled Asset Relief Program, the U.S. Department of Housing and Urban Development, various State mortgage banking regulators and various State Attorneys General, related to the Company’s residential loan servicing and origination practices, its financial reporting and other aspects of its businesses. Any pending or potential future investigations, subpoenas, examinations or inquiries may lead to administrative, civil or criminal proceedings or settlements, and possibly result in remedies including fines, penalties, restitution, or alterations in the Company’s business practices, and additional expenses and collateral costs. The Company is cooperating fully in these matters. Responding to these matters requires the Company to devote substantial resources, resulting in higher costs and lower net cash flows. Adverse results in any of these matters could further increase the Company’s operating expenses and reduce its revenues, require it to change business practices and limit its ability to grow and otherwise materially and adversely affect its business, reputation, financial condition and results of operation. The Company seeks to resolve all legal proceedings and other matters in the manner management believes is in the best interest of the Company and contests liability, allegations of wrongdoing and, where applicable, the amount of damages or scope of any penalties or other relief sought as appropriate in each pending matter. The Company has entered into agreements with a number of entities and regulatory agencies that toll applicable limitations periods with respect to their claims. On at least a quarterly basis, the Company assesses its liabilities and contingencies in connection with outstanding legal and regulatory and governmental proceedings utilizing the latest information available. Where available information indicates that it is probable, a liability has been incurred, and the Company can reasonably estimate the amount of the loss, an accrued liability is established. The actual costs of resolving these proceedings may be substantially higher or lower than the amounts accrued. As a legal matter develops, the Company, in conjunction with any outside counsel handling the matter, evaluates on an ongoing basis whether such matter presents a loss contingency that is both probable and estimable. If, at the time of evaluation, the loss contingency is not both probable and reasonably estimable, the matter will continue to be monitored for further developments that would make such loss contingency both probable and reasonably estimable. Once the matter is deemed to be both probable and reasonably estimable, the Company will establish an accrued liability and record a corresponding amount to legal-related expense. The Company will continue to monitor the matter for further developments that could affect the amount of the accrued liability that has been previously established. Legal-related expense for the Company, which includes legal settlements and the fees paid to external legal service providers, of $8 and $21 for three and six months ended June 30, 2021, respectively, and $12 and $27 for three and six months ended June 30, 2020, respectively, was included in general and administrative expenses on the unaudited condensed consolidated statements of operations. For matters for which a loss is probable or reasonably possible in future periods, whether in excess of a related accrued liability or where there is no accrued liability, the Company may be able to estimate a range of possible loss. In determining whether it is possible to provide an estimate of loss or range of possible loss, the Company reviews and evaluates its material legal matters on an ongoing basis, in conjunction with any outside counsel handling the matter. Management currently believes the aggregate range of reasonably possible loss is $2 to $17 in exce ss of the accrued liability (if any) related to those matters as of June 30, 2021. This estimated range of possible loss i s based upon currently available information and is subject to significant judgment, numerous assumptions and known and unknown uncertainties. The matters underlying the estimated range will change from time to time, and actual results may vary substantially from the current estimate. Those matters for which an estimate is not possible are not included within the estimated range. Therefore, this estimated range of possible loss represents what management believes to be an estimate of possible loss only for certain matters meeting these criteria. It does not represent the Company’s maximum loss exposure and the Company cannot provide assurance that its litigations reserves will not need to be adjusted in the future. Thus, the Company’s exposure and ultimate losses may be higher, possibly significantly so, than the amounts accrued or this aggregate amount. In the Company’s experience, legal proceedings are inherently unpredictable. One or more of the following factors frequently contribute to this inherent unpredictability: the proceeding is in its early stages; the damages sought are unspecified, unsupported or uncertain; it is unclear whether a case brought as a class action will be allowed to proceed on that basis or, if permitted to proceed as a class action, how the class will be defined; the other party is seeking relief other than or in addition to compensatory damages (including, in the case of regulatory and governmental investigations and inquiries, the possibility of fines and penalties); the matter presents meaningful legal uncertainties, including novel issues of law; the Company has not engaged in meaningful settlement discussions; discovery has not started or is not complete; there are significant facts in dispute; predicting possible outcomes depends on making assumptions about future decisions of courts or governmental or regulatory bodies or the behavior of other parties; and there are a large number of parties named as defendants (including where it is uncertain how damages or liability, if any, will be shared among multiple defendants). Generally, the less progress that has been made in the proceedings or the broader the range of potential results, the harder it is for the Company to estimate losses or ranges of losses that is reasonably possible the Company could incur. Based on current knowledge, and after consultation with counsel, management believes that the current legal accrued liability within payables and accrued liabilities, is appropriate, and the amount of any incremental liability arising from these matters is not expected to have a material adverse effect on the consolidated financial condition of the Company, although the outcome of such proceedings could be material to the Company’s operating results and cash flows for a particular period depending, on among other things, the level of the Company’s revenues or income for such period. However, in the event of significant developments on existing cases, it is possible that the ultimate resolution, if unfavorable, may be material to the Company’s condensed consolidated financial statements. Other Loss Contingencies As part of the Company’s ongoing operations, it acquires servicing rights of forward mortgage loan portfolios that are subject to indemnification based on the representations and warranties of the seller. From time to time, the Company will seek recovery under these representations and warranties for incurred costs. The Company believes all balances sought from sellers recorded in advances and other receivables represent valid claims. However, the Company acknowledges that the claims process can be prolonged due to the required time to perfect claims at the loan level. Because of the required time to perfect or remediate these claims, management relies on the sufficiency of documentation supporting the claim, current negotiations with the counterparty and other evidence to evaluate whether a reserve is required for non-recoverable balances. In the absence of successful negotiations with the seller, all amounts claimed may not be recovered. Balances may be written-off and charged against earnings when management identifies amounts where recoverability from the seller is not likely. As of June 30, 2021, the Company believes all recorded balances for which recovery is sought from the seller are valid claims, and no evidence suggests additional reserves are warranted. Loan and Other Commitments The Company enters into IRLCs with prospective borrowers whereby the Company commits to lend a certain loan amount under specific terms and interest rates to the borrower. The Company also enters into LPCs with prospective sellers. These loan commitments are treated as derivatives and are carried at fair value. See Note 8, Derivative Financial Instruments , for more information.

Segment Reporting [Abstract]
Segment Information	16. Segment Information The Company’s segments are based upon the Company’s organizational structure, which focuses primarily on the services offered. Corporate functional expenses are allocated to individual segments based on the actual cost of services performed, direct resource utilization, estimate of percentage use for shared services or headcount percentage for certain functions. Facility costs are allocated to individual segments based on cost per headcount for specific facilities utilized. Group insurance costs are allocated to individual segments based on global cost per headcount. Non-allocated corporate expenses include the administrative costs of executive management and other corporate functions that are not directly attributable to Company’s operating segments. Revenues generated on inter-segment services performed are valued based on similar services provided to external parties. On June 30, 2021, the Company closed the previously announced sale of title business to Blend Labs. Pursuant to the Stock Purchase Agreement, all cash generated, subject to certain adjustments, between March 13, 2021 and the closing date of the Title Transaction, were held for the benefit of Blend Labs. The title business was reported in the Company’s Xome segment. See Note 1, Nature of Business and Basis of Presentation for further details . The Company recorded a $487 gain in the second quarter of 2021 upon closing of the transaction. The gain was included in other income, net in the condensed statements of operations and reported under the Xome segment. On July 1, 2021, the Company entered into a definitive agreement for the sale of its reverse servicing portfolio, operating under the Champion Mortgage brand, to Mortgage Assets Management, LLC and its affiliates. The reverse servicing operation was previously reported in the Company’s Servicing segment. The reverse servicing operation is presented as discontinued operations in Company’s condensed consolidated financial statements for all periods presented and as such is not included in the continuing operations of the Servicing segment. Refer to Note 2, Discontinued Operations for further details. As of June 30, 2021 and December 31, 2020 , total assets of discontinued operations was $4,935 and $5,347, respectively.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	Basis of Presentation The interim condensed consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission. Accordingly, the financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Reports on Form 10-K for the year ended December 31, 2020.
Basis of consolidation	Basis of ConsolidationThe condensed consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries, other entities in which the Company has a controlling financial interest and those variable interest entities (“VIE”) where the Company’s wholly-owned subsidiaries are the primary beneficiaries. Assets and liabilities of VIEs and their respective results of operations are consolidated from the date that the Company became the primary beneficiary through the date the Company ceases to be the primary beneficiary. The Company applies the equity method of accounting to investments where it is able to exercise significant influence, but not control, over the policies and procedures of the entity and owns less than 50% of the voting interests. Investments in certain companies over which the Company does not exert significant influence are accounted for as cost method investments. Intercompany balances and transactions on consolidated entities have been eliminated.
Use of estimates	Use of Estimates The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from these estimates due to factors such as adverse changes in the economy, changes in interest rates, secondary market pricing for loans held for sale and derivatives, strength of underwriting and servicing practices, changes in prepayment assumptions, declines in home prices or discrete events adversely affecting specific borrowers, uncertainties in the economy from the COVID-19 pandemic, and such differences could be material. In the second quarter of 2021, the Company refined its estimation process for determining the fair value of forward MSRs by incorporating an estimate of future cash flows from existing loans that are expected to be recaptured, which is consistent with recent pricing observed from market participants. This refinement did not result in a significant change to the overall valuation of the Company’s mortgage servicing rights (“MSRs”) portfolio . See Note 3, Mortgage Servicing Rights and Related Liabilities and Note 13, Fair Value Measurements for further discussion. There were no other changes to the Company’s use of estimates for the period ended June 30, 2021
