Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business and Basis of Presentation	Nature of Business and Basis of Presentation
	Nature of Business
	Nationstar Mortgage Holdings Inc., a Delaware corporation, including its consolidated subsidiaries (collectively, Nationstar or the Company), earns fees through the delivery of servicing, origination and transaction based services related principally to single-family residences throughout the United States.
	Basis of Presentation
	The consolidated financial statements include the accounts of Nationstar, its wholly-owned subsidiaries, and other entities in which the Company has a controlling financial interest, and those variable interest entities (VIEs) where Nationstar's wholly-owned subsidiaries are the primary beneficiaries. Nationstar applies the equity method of accounting to investments when the entity is not a VIE and Nationstar is able to exercise significant influence, but not control, over the policies and procedures of the entity but owns less than 50% of the voting interests. Intercompany balances and transactions have been eliminated. Results of operations, assets and liabilities of VIEs are included from the date that Nationstar became the primary beneficiary through the date Nationstar ceases to be the primary beneficiary.
	The interim consolidated financial statements are unaudited; however, in the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the results of the interim periods have been included. The consolidated interim financial statements of Nationstar have been prepared in accordance with generally accepted accounting principles for interim 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 (SEC). Accordingly, the financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States (GAAP) for complete financial statements and should be read in conjunction with the audited consolidated financial statements and notes thereto included in Nationstar's Annual Report on Form 10-K filed on February 27, 2015. The results of operations for the interim periods disclosed are not necessarily indicative of the results that may be expected for the full year or any future period. Certain prior period amounts have been reclassified to conform to the current period presentation. Nationstar evaluated subsequent events through the date these interim consolidated financial statements were issued.
	Recent Accounting Developments
	Accounting Standards Update 2015-02: Consolidation (Topic 810) - Amendments to the Consolidation Analysis (ASU 2015-02) changes the analysis that a reporting entity must perform when deciding to consolidate a legal entity. This amendment changes the evaluation of whether limited partnerships are variable interest entities or voting interest entities and eliminates the presumption that a general partner should consolidate a limited partnership. This amendment also changes the analysis for entities that are involved with variable interest entities and provides an exception for companies with interests in entities that are required to comply with requirements of the Investment Company Act of 1940 for registered money market funds. The amendment is effective for fiscal years and interim periods beginning after December 15, 2015. The Company is currently evaluating the impact of adopting ASU 2015-02.
	Accounting Standards Update 2015-03: Interest - Imputation of Interest (Subtopic 835-30) - Simplifying the Presentation of Debt Issuance Costs (ASU 2015-03) requires that debt issuance costs be included in the carrying value of the related debt liability, when recognized, on the face of the balance sheet. This amendment is effective for fiscal years beginning after December 15, 2015. The Company is currently evaluating the impact of adopting ASU 2015-03.
	Accounting Standards Update 2015-05 - Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) - Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement (ASU 2015-05) was created to eliminate diversity in the reporting of fees paid by a customer in a cloud computing arrangement caused by lack of guidance. This update provides that if a cloud computing arrangement includes a software license, the license element should be accounted for as other acquired software licenses. If the cloud computing arrangement does not include a software license then the fees should be accounted for as a service contract. This amendment is effective for annual periods beginning after December 15, 2015. The Company is currently evaluating the impact of adopting ASU 2015-05.
	Accounting Standards Update No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40), Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (ASU 2014-15), creates consistency in the disclosures made by an entity when there is doubt that the entity will continue as a going concern. ASU 2014-15 is effective for annual periods ending after December 15, 2016. The adoption of ASU 2014-15 is not expected to have a material impact on our financial condition, liquidity or results of operations.
	ASU No. 2014-12, Compensation-Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (ASU 2014-12), requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. ASU 2014-12 is effective for annual and interim periods beginning after December 15, 2015, with early adoption permitted. The adoption of ASU 2014-12 is not expected to have a material impact on our financial condition, liquidity or results of operation.
	Accounting Standards Update 2015-01: Income Statement - Extraordinary and Unusual Items (Subtopic 225-20), Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items (ASU 2015-01) eliminates the concept of extraordinary items from GAAP. ASU 2015-01 is effective for fiscal years beginning after December 15, 2015. The adoption of
	ASU 2015-01 is not expected to have a material impact on our financial condition, liquidity or results of operations.
	Effective January 1, 2015, the Company adopted Accounting Standards Update No. 2014-14, Receivables — Troubled Debt Restructurings by Creditors (Subtopic 310-40), Classification of Certain Government-Guaranteed Loans Upon Foreclosure (ASU 2014-14). This update requires that foreclosed mortgage loans guaranteed by the government be derecognized and a separate other receivable recognized if certain conditions are met. Upon adoption of this ASU, foreclosed loans backed by government guarantees that were previously recorded as a component of Real Estate Owned in Other Assets were reclassified to Reverse Mortgage Interests on the Company's consolidated balance sheet. Consistent with the Company's adoption of ASU 2014-14, prior year amounts were reclassified to be in conformity with the current year presentation. The adoption of ASU 2014-14 did not have an impact to the Company's net income.
	Effective January 1, 2015, the Company adopted Accounting Standards Update No. 2014-04, Receivables — Troubled Debt Restructurings by Creditors (Subtopic 310-40), Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans Upon Foreclosure (ASU 2014-04). This update requires disclosure of consumer mortgage loans collateralized by residential real estate for which formal foreclosure proceedings are in process. Consistent with the Company's adoption of ASU 2014-04, the Company made the required disclosure for current and prior year in the Mortgage Loans Held for Sale and Investment footnote. The adoption of ASU 2014-04 did not have an impact to the Company's net income.

	Mortgage Servicing Rights - Fair Value
	MSRs - Fair Value consists of rights the Company owns and records as assets to service traditional residential mortgage loans for others either as a result of a purchase transaction or from the sale and securitization of loans originated. MSRs - Fair Value comprise both agency and non-agency loans. The Company segregates MSRs - Fair Value between credit sensitive and interest sensitive pools. Interest sensitive pools are primarily impacted by changes in forecasted interest rates, which in turn impact voluntary prepayment speeds. Credit sensitive pools are primarily impacted by borrower performance under specified repayment terms, which most directly impacts involuntary prepayments and delinquency rates.
	The Company assesses whether acquired portfolios are more credit sensitive or interest sensitive in nature on the date of acquisition. The Company considers numerous factors in making this assessment, including loan-to-value ratios, FICO scores, percentage of portfolio previously modified, portfolio seasoning and similar criteria. Once the determination for a pool is made, it is not changed over time.
	Interest sensitive portfolios consist of lower delinquency single-family conforming residential forward mortgage agency loans. Credit sensitive portfolios primarily consist of higher delinquency single-family non-conforming residential forward mortgage loans serviced both for agency and non-agency investors.
	The following table provides a breakdown of the total credit and interest sensitive UPBs for Nationstar's owned MSRs.
		31-Mar-15								31-Dec-14
		UPB				Fair Value				UPB				Fair Value
	Credit Sensitive	$	241,252,341			$	2,002,487			241,769,601				1,919,290
	Interest Sensitive	101,866,277				1,019,711				91,843,044				1,030,449
		$	343,118,618			$	3,022,198			$	333,612,645			$	2,949,739
	The activity of MSRs carried at fair value is as follows for the dates indicated:
		Three months ended,
		31-Mar-15				31-Mar-14
	Fair value at the beginning of the period	$	2,949,739			$	2,488,283
	Additions:
	Servicing resulting from transfers of financial assets	44,232				58,304
	Purchases of servicing assets	238,413				108,312
	Changes in fair value:
	Due to changes in valuation inputs or assumptions used in the valuation model	(109,684		)		(3,083		)
	Other changes in fair value	(100,502		)		(75,266		)
	Fair value at the end of the period	$	3,022,198			$	2,576,550
	In the fourth quarter of 2014, the Company revised its approach in calculating Other Changes in Fair Value in the above rollforward. Under the revised approach, Nationstar began incorporating voluntary principal payments, which were previously included as a component in the Due to changes in valuation inputs or assumptions line, as a component in Other changes in fair value. Nationstar has reclassified the amounts presented in the March 31, 2014 rollforward to conform to the current presentation. While amounts were reclassed in the 2014 period, there was no impact to net income or to the total changes in fair value in the prior period.
	Nationstar used the following weighted average assumptions in estimating the fair value of MSRs for the dates indicated:
	Credit Sensitive	31-Mar-15			31-Dec-14
	Discount rate	11.79	%		11.96	%
	Total prepayment speeds	18.14	%		18.58	%
	Expected weighted-average life	5.74 years			5.39 years
	Interest Sensitive	31-Mar-15			31-Dec-14
	Discount rate	9.08	%		9.09	%

	These sensitivities are hypothetical and should be evaluated with care. The effect on fair value of a 10% variation 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.
	MSRs - LOCOM
	Nationstar owns the right to service certain reverse mortgages with an unpaid principal balance of $27.4 billion and $28.0 billion as of March 31, 2015 and December 31, 2014, respectively. Nationstar utilizes a variety of assumptions in assessing the fair value of its servicing assets or liabilities, with the primary assumptions including discount rates, prepayment speeds, home price index, collateral values and the expected weighted average life. At March 31, 2015 and December 31, 2014, no impairment was identified. Interest and servicing fees collected on reverse mortgage interests are included as a component of either interest income or service related revenues based on whether Nationstar acquired the related borrower draws from a predecessor servicer or funded borrower draws under its obligation to service the related HECMs subsequent to the acquisition of the rights to service these loans.

Fair value at end of period	$	32,618			$	55,579			$	38,430			$	68,965
For the three month period ended March 31, 2015, the Company accreted $6.8 million of the mortgage servicing liability as a result of increased HECM loan repurchase activity. Issuers of HECMs are responsible for repurchasing any loans out of the HMBS pool when the outstanding principal balance of the related HECM loan is equal to or greater than 98% of the lesser of the appraised value of the underlying property at origination or $625 thousand.
Excess Spread Financing at Fair Value
In conjunction with Nationstar's acquisition of certain MSRs on various pools of residential mortgage loans (the Portfolios), Nationstar has entered into sale and assignment agreements with certain entities formed by New Residential Investment Corp. (New Residential) in which New Residential and/or certain funds managed by Fortress Investment Group LLC (Fortress) own an interest. Nationstar, in transactions accounted for as financing arrangements, sold to such entities the right to receive a specified percentage of the excess cash flow generated from the Portfolios after receipt of a fixed basic servicing fee per loan. Nationstar has elected fair value accounting for these financing agreements.
Servicing fees associated with a traditional MSR can be segregated into a base servicing fee and an excess servicing fee. The base servicing fee, along with ancillary income, is meant to cover costs incurred to service the specified pool plus a reasonable profit margin. The remaining servicing fee is considered excess.
Nationstar retains all the base servicing fee and ancillary revenues associated with servicing the Portfolios and the retained portion of the excess servicing fee. Nationstar continues to be the servicer of the Portfolio and provides all servicing and advancing functions. New Residential has no prior or ongoing obligations associated with the Portfolio.
Contemporaneous with the above, Nationstar entered into refinanced loan agreements with New Residential. Should Nationstar refinance any loan in the Portfolios, subject to certain limitations, Nationstar can be required to transfer the new loan or a replacement loan of similar economic characteristics into the Portfolios. The new or replacement loan will be governed by the same terms set forth in the sale and assignment agreement described above.
The range of various assumptions used in Nationstar's valuation of Excess Spread financing were as follows:
Excess Spread financing	Prepayment Speeds		Average		Discount		Recapture Rate
			Life (years)		Rate
31-Mar-15
Low	8.20%		3.9 years		8.50%		6.70%
High	18.50%		7.8 years		14.20%		31.20%
31-Dec-14
Low	6.20%		4.0 years		8.50%		6.70%
High	19.40%		7.1 years		14.20%		31.30%
The following table shows the hypothetical effect on the fair value of excess spread financing using certain unfavorable variations of the expected levels of key assumptions used in valuing these liabilities at the dates indicated:
	Discount Rate							Total Prepayment
								Speeds
	100 bps			200 bps				10%			20%
	Adverse			Adverse				Adverse			Adverse
	Change			Change				Change			Change
31-Mar-15
Excess spread financing	$	38,747		$	80,440			$	34,326		$	71,911
31-Dec-14
Excess spread financing	$	36,632		$	75,964			$	33,618		$	70,379
As the cash flow assumptions utilized in determining the fair value amounts in the excess spread financing are based on the related cash flow assumptions utilized in the financed MSRs, any fair value changes recognized in the MSRs would inherently have an inverse impact on the carrying amount in the related excess spread financing. For example, while an increase in discount rates would negatively impact the value of the Company's MSRs, it would reduce the carrying value of the associated excess spread financing liability and provide a benefit to the Company's net service related revenue.
These sensitivities are hypothetical and should be evaluated with care. The effect on fair value of a 10% variation 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.
Mortgage Servicing Rights Financing
Nationstar has entered into agreements to sell a contractually specified basic fee component of certain MSRs and servicer advances under specified terms. Nationstar continues to be the named servicer and, for accounting purposes, ownership of the mortgage servicing rights continues to reside with Nationstar. Nationstar continues to account for the MSRs on its consolidated balance sheets. In addition, Nationstar records a MSRs financing liability associated with this financing transaction. See Note 18, Disclosures Related to Transactions with Affiliates of Fortress Investment Group LLC for additional information.
Nationstar has elected to measure the mortgage servicing rights financings at fair value with all changes in fair value recorded as a charge or credit to servicing related revenue in the consolidated statements of income (loss) and comprehensive income (loss). The weighted average assumptions used in Nationstar's valuation of Mortgage Servicing Rights Financing were as follows:
	31-Mar-15			31-Dec-14
Advance financing rates	2.72	%		2.79	%
Annual advance recovery rates	24.91	%		27.55	%

		31-Mar-15		31-Dec-14
	Advances	$	2,470,315	$	2,546,362
	Servicing advances on non-agency securities are typically recovered first at a loan-level from proceeds of the mortgage loans for which the advance was made, and then if loan-level funds are determined to be ultimately insufficient, from cash collected from all borrowers in a securitization trust. For advances on agency securities, servicing advances represent a receivable from the respective agency and are recovered from cash collections in a securitization trust and/or a requested reimbursement from the agency.
	Nationstar accretes purchase discounts into interest income as the related servicer advances are recovered. During the quarters ended March 31, 2015 and 2014 the Company accreted $0.3 million and $3.8 million, respectively, of the purchase discounts from recovered servicer advances.
	In 2014, Nationstar sold approximately $2.5 billion of servicer advances to a joint venture entity capitalized by New Residential and other investors (Mortgage Servicing Rights Financing Liability). See Note 18, Disclosures Related to Transactions with Affiliates of Fortress Investment Group LLC, for additional information. Consequently, the related purchase discount of $52.9 million was eliminated from Nationstar's consolidated balance sheet.
	As of March 31, 2015 and December 31, 2014, Nationstar carried an allowance for uncollectible servicer advances of $10.6 million and $9.2 million, respectively.

	Other interests securitized consists of reverse mortgage interests which have been transferred to private securitization trusts and are subject to nonrecourse debt. Nationstar evaluated these trusts to determine whether they meet the definition of a VIE and whether Nationstar is the primary beneficiary. See Note 10, Securitizations and Financing.
	Unsecuritized interests consist primarily of recently funded borrower draws that have not yet been sold into a GNMA HECM securitization, GNMA HECMs that have been repurchased out of a GNMA HECM securitization since they have reached 98% or more of the maximum claim amount, repurchased GNMA HECM interests that have been assigned to the FHA for reimbursement, foreclosed assets, and advances made on inactive loans that cannot be securitized due to the delinquency status of the loan. Under the GNMA HMBS program, the company is required to repurchase a HECM loan from the HMBS pool when the outstanding principal balance of the HECM loan is equal to or greater than 98% of the maximum claim amount.
	Nationstar collectively evaluates all reverse mortgage interest assets for impairment.
	In 2015, Nationstar adopted ASU 2014-14. As a result of this adoption, the Company reclassified $68.9 million and $69.4 million of real estate owned (previously recorded as a component of other assets) to reverse mortgage interest as of March 31, 2015 and December 31, 2014, on its consolidated balance sheet.

	Mortgage loans held for sale
	Nationstar maintains a strategy of originating mortgage loan products primarily for the purpose of selling to government-sponsored enterprises (GSEs) or other third-party investors, primarily Ginnie Mae, in the secondary market. Nationstar primarily focuses on assisting customers currently in the Company's servicing portfolio with refinances of loans for new home purchases (or recapture). Generally, all newly originated mortgage loans held for sale are delivered to third-party purchasers or securitized shortly after origination.

	Nationstar, as the servicer has the right to repurchase any individual loan in a Ginnie Mae securitization pool if that loan meets certain criteria, including being delinquent greater than 90 days. The majority of Ginnie Mae repurchased loans are repurchased solely with the intent to repool into new Ginnie Mae securitizations or to otherwise sell to third-party investors. For the three months ended March 31, 2015 and March 31, 2014, Nationstar repurchased out of Ginnie Mae securitization pools $0.4 billion and $0.6 billion of mortgage loans, respectively.

	Nationstar may periodically modify the terms of any outstanding mortgage loans held for investment, net for loans that are either in default or in imminent default. Modifications often involve reduced payments by borrowers, modification of the original terms of the mortgage loans, forgiveness of debt and/or modified servicing advances. As a result of the volume of modification agreements entered into, the estimated average outstanding life in this pool of mortgage loans has been extended. Nationstar records interest income on the transferred loans on a level-yield method. To maintain a level-yield on these transferred loans over the estimated extended life, Nationstar reclassified approximately $0.3 million of transfer discount to accretable yield for the three months ended March 31, 2015 and $1.1 million for the year ended December 31, 2014. Furthermore, Nationstar considers the decrease in principal, interest, and other cash flows expected to be collected arising from the transferred loans as an impairment.
	Loan delinquency and Loan-to-Value Ratio (LTV) are common credit quality indicators that Nationstar monitors and utilizes in
	its evaluation of the adequacy of the allowance for loan losses, of which the primary indicator of credit quality is loan delinquency status. LTV refers to the ratio of the loan’s unpaid principal balance to the property’s collateral value. Loan delinquencies and unpaid principal balances are updated monthly based upon collection activity. Collateral values are updated from third party providers on a periodic basis. The collateral values used to derive LTV’s are obtained at various dates, but the majority were within the last twenty-four months. For an event requiring a decision based at least in part on the collateral value, the Company takes its last known value provided by a third party and then adjusts the value based on the applicable home price index.
	The total UPB of mortgage loans held for investment for which the Company has begun formal foreclosure proceedings was as follows for the dates indicated:

	For certain loans that Nationstar sold to Ginnie Mae, Nationstar as the issuer has the unilateral right to repurchase, without Ginnie Mae’s prior authorization, any individual loan in a Ginnie Mae securitization pool if that loan meets certain criteria, including being delinquent greater than 90 days. Once Nationstar has the unilateral right to repurchase a delinquent loan, Nationstar has effectively regained control over the loan, and under GAAP, must re-recognize the loan on its consolidated balance sheets and establish a corresponding repurchase liability regardless of Nationstar’s intention to repurchase the loan. Nationstar’s re-recognized loans included in other assets and the corresponding liability in payables and accrued liabilities was $118.6 million at March 31, 2015 and $131.6 million at December 31, 2014.
	In 2015, Nationstar adopted ASU 2014-14. As a result of this adoption, the Company reclassified $43.6 million and $36.0 million of Real Estate Owned to Receivables from trusts, agencies and prior servicers, net, as of March 31, 2015 and December 31, 2014, both of which are a component of Other Assets on the consolidated balance sheet.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments
	Derivatives instruments utilized by Nationstar primarily include interest rate lock commitments (IRLCs), Loan Purchase Commitments (LPCs), Forward MBS trades, Eurodollar futures and interest rate swap agreements.
	Nationstar enters into IRLCs with prospective borrowers. These commitments are carried at fair value, with any changes in fair value recorded in earnings as a component of net gain on mortgage loans held for sale. The estimated fair values of IRLCs are based on the fair value of the related mortgage loans which is based on observable market data and is recorded in derivative financial instruments within the consolidated balance sheets. Nationstar adjusts the outstanding IRLCs with prospective borrowers based on an expectation that it will be exercised and the loan will be funded.
	Nationstar actively manages the risk profiles of its IRLCs and mortgage loans held for sale on a daily basis. To manage the price risk associated with IRLCs, Nationstar enters into forward sales of MBS in an amount equal to the portion of the IRLC expected to close, assuming no change in mortgage interest rates. In addition, to manage the interest rate risk associated with mortgage loans held for sale, Nationstar enters into forward sale commitments to deliver mortgage loan inventory to investors. The estimated fair values of forward sales of MBS and forward sale commitments are based on exchange prices or the dealer market price and are recorded as a component of derivative financial instruments and mortgage loans held for sale, respectively, in the consolidated balance sheets. The initial and subsequent changes in value on forward sales of MBS and forward sale commitments are a component of net gain on mortgage loans held for sale.
	Nationstar may occasionally enter into contracts with other mortgage lenders to purchase residential mortgage loans at a future date, which are referred to as LPCs. LPCs are accounted for as derivatives and recorded at fair value in derivative financial instruments on Nationstar's consolidated balance sheet. Subsequent changes in LPCs are recorded as a charge or credit to net gain on mortgage loans held for sale.
	In addition, Nationstar enters into Eurodollar futures contracts to replicate the economic hedging results achieved with interest rate swaps or offset the changes in value of its forward sales of certain agency securities. The Company has not designated its futures contracts as hedges for accounting purposes. As a result, realized and unrealized changes in fair value are recognized in net gain on mortgage loans held for sale in the period in which the changes occur.
	Periodically, Nationstar has entered into interest rate swap agreements to hedge the interest payment on the warehouse debt and
	securitization of its mortgage loans held for sale. These interest rate swap agreements generally require Nationstar to pay a fixed interest rate and receive a variable interest rate based on LIBOR. Unless designated as an accounting hedge, Nationstar records gains and losses on interest rate swaps as a component of gain/(loss) on interest rate swaps and caps in Nationstar’s consolidated statements of income (loss) and comprehensive income (loss). Unrealized losses on dedesignated interest rate derivatives are separately disclosed under operating activities in the consolidated statements of cash flows.
	Historically, Nationstar has entered into interest rate swap agreements to hedge the interest payments associated with its outstanding floating rate financing servicer advance facilities. Prior to March 31, 2014, certain of these derivatives were designated as cash flow hedges and were recorded at fair value on Nationstar's balance sheet, with any change in fair value being recorded as an adjustment to other comprehensive income. On March 31, 2014, the Company dedesignated the remainder of the interest rate swap agreements, with any further changes in fair value being recorded as a charge to gain or loss in interest rate swaps and caps in Nationstar's consolidated statements of income (loss) and comprehensive income (loss).
	Associated with the Company's forward MBS trades are $11.5 million and $9.8 million in collateral deposits on derivative instruments recorded in other assets on the Company's balance sheets as of March 31, 2015 and December 31, 2014, respectively. The Company does not offset fair value amounts recognized for derivative instruments and the amounts collected and/or deposited on derivative instruments in its consolidated balance sheets.

	Total	$	2,158,812		$	2,159,231
	The indentures for the unsecured senior notes contain various covenants and restrictions that limit Nationstar's ability to incur additional indebtedness, pay dividends, make certain investments, create liens, consolidate, merge or sell substantially all of its assets, or enter into certain transactions with affiliates. The indentures contain certain events of default, including (subject, in some cases, to customary cure periods and materiality thresholds) defaults based on (i) the failure to make payments under the indenture when due, (ii) breach of covenants, (iii) cross-defaults to certain other indebtedness, (iv) certain bankruptcy or insolvency events, (v) material judgments and (vi) invalidity of material guarantees.
	The indentures for the unsecured senior notes provide that Nationstar may redeem all or a portion of the notes prior to certain fixed dates by paying a make-whole premium plus accrued and unpaid interest and additional interest, if any, to the redemption dates. In addition, Nationstar may redeem all or a portion of the senior notes at any time on or after certain fixed dates at the applicable redemption prices set forth in the indentures plus accrued and unpaid interest and additional interest, if any, to the redemption dates.
	Additionally, the indentures provide that on or before certain fixed dates, Nationstar may redeem up to 35% of the aggregate principal amount of the senior notes with the net proceeds of certain equity offerings at fixed redemption prices, plus accrued and unpaid interest and additional interest, if any, to the redemption dates, subject to compliance with certain conditions.
	The ratios included in the indentures for the Unsecured Senior Notes are incurrence-based compared to the customary ratio covenants that are often found in credit agreements that require a company to maintain a certain ratio.
	As of March 31, 2015, the expected maturities of Nationstar's unsecured senior notes based on contractual maturities are as follows:

	Total	$	1,870,269		$	1,768,311
	Participating Interest Financing
Participating interest financing represents the issuance of pools of HMBS to third-party security holders which are guaranteed by certain GSEs. Nationstar has accounted for the transfer of these advances in the related HECM loans as secured borrowings, retaining the initial reverse mortgage interests on its consolidated balance sheet, and recording the pooled HMBS as participating interest financing liabilities on the Company’s consolidated balance sheet. Monthly cash flows generated from the HECM loans are used to service the HMBS. The interest rate is based on the underlying HMBS rate with a range of 0.14% to 6.98%. The participating interest financing was $1,491.5 million and $1,433.1 million at March 31, 2015 and December 31, 2014, respectively.
2014-1 HECM Securitization
In December 2014, Nationstar Mortgage LLC completed the securitization of approximately $343.6 million in Nationstar HECM Loan Trust 2014-1Mortgage Backed Securities. The trust was created to provide investors with the ability to invest in a pool of non-performing home equity conversion reverse mortgage loans that are covered by Federal Housing Administration (FHA) insurance and secured by one to four-family residential properties and a pool of REO properties acquired through foreclosure or grant of a deed in lieu of foreclosure in connection with reverse mortgage loans that are covered by FHA insurance. The transaction provides Nationstar with access to liquidity for the acquired non-performing HECM loan portfolio, ongoing servicing fees, and potential residual returns.
The notes were issued under two separate classes, comprised of Class A Notes and Class M Notes. As part of the securitization, Nationstar retained a portion of the offered Class A notes of approximately $70.4 million as well as the Class M Notes with an outstanding note balance of $36.2 million. A portion of the notes retained by Nationstar represent subordinated beneficial interests. In the first quarter 2015, the Company sold the remaining retained portions of the Class A and the Class M notes for total proceeds of $73.1 million.
The transaction was structured as a secured borrowing with the reverse mortgage loans included in the consolidated financial statements as a reverse secured borrowing and the related financing included in other nonrecourse debt. The nonrecourse debt totaled $305.7 million and $259.3 million at March 31, 2015 and December 31, 2014, respectively.
Nonrecourse Debt–Legacy Assets
In November 2009, Nationstar completed the securitization of approximately $222.0 million of ABS, which was accounted for as a secured borrowing. This structure resulted in Nationstar carrying the securitized mortgage loans on Nationstar’s consolidated balance sheet and recognizing the asset-backed certificates acquired by third parties as nonrecourse debt, totaling approximately $73.0 million and $75.8 million at March 31, 2015, and December 31, 2014, respectively. The principal and interest on these notes are paid using the cash flows from the underlying mortgage loans, which serve as collateral for the debt. The interest rate paid on the outstanding securities is 7.50%, which is subject to an available funds cap. The total outstanding principal balance on the underlying mortgage loans serving as collateral for the debt was approximately $260.0 million and $268.2 million at March 31, 2015 and December 31, 2014, respectively. The timing of the principal payments on this nonrecourse debt is dependent on the payments received on the underlying mortgage loans. The unpaid principal balance on the outstanding notes was $84.9 million and $88.2 million at March 31, 2015 and December 31, 2014, respectively.
Financial Covenants
The Company's borrowing arrangements and credit facilities contain various financial covenants which primarily relate to required tangible net worth amounts, liquidity reserves, leverage requirements, and profitability requirements. As a result of the decrease in interest rates during the three month period ended March 31, 2015, Nationstar recorded a charge to service related revenues for changes in fair value associated with the Company's MSRs recorded at fair value. As a result of the charge, Nationstar was unable to meet the profitability requirements in two of its outstanding warehouse facilities and one MBS facility. Nationstar asked for, and received, a waiver from these financial institutions on these profitability requirements for the period ending March 31, 2015. With the exception of this waiver, the Company was in compliance with all other required financial covenants as of March 31, 2015.
Nationstar is required to maintain a minimum tangible net worth of at least $450.0 million as of each quarter-end related to its outstanding Master Repurchase Agreements on its outstanding repurchase facilities. As of March 31, 2015, Nationstar was in compliance with these minimum tangible net worth requirements.

Fair_Value_Measurements

Fair Value Measurements	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements
	Fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement 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).
	The following describes the methods and assumptions used by Nationstar in estimating fair values:
	Cash and Cash Equivalents, Restricted Cash (Level 1) – The carrying amount reported in the consolidated balance sheets approximates fair value.
	Mortgage Loans Held for Sale (Level 2) – Nationstar originates mortgage loans in the U.S. that it intends to sell to Fannie Mae, Freddie Mac, and Ginnie Mae (collectively, the Agencies). Additionally, Nationstar holds mortgage loans that it intends to sell into the secondary markets via whole loan sales or securitizations. Nationstar measures newly originated prime residential mortgage loans held for sale at fair value.
	Mortgage loans held for sale are typically pooled together and sold into certain exit markets, depending upon underlying attributes of the loan, such as agency eligibility, product type, interest rate, and credit quality. Mortgage loans held for sale are valued on a recurring basis using a market approach by utilizing either: (i) the fair value of securities backed by similar mortgage loans, adjusted for certain factors to approximate the fair value of a whole mortgage loan, including the value attributable to mortgage servicing and credit risk, (ii) current commitments to purchase loans or (iii) recent observable market trades for similar loans, adjusted for credit risk and other individual loan characteristics. As these prices are derived from market observable inputs, Nationstar classifies these valuations as Level 2 in the fair value disclosures.
	The Company may acquire mortgage loans held for sale from various securitization trusts for which it acts as servicer through the exercise of various clean-up call options as permitted through the respective pooling and servicing agreements. The Company has elected to account for these loans at the lower of cost or market. Nationstar classifies these valuations as Level 2 in the fair value disclosures.
	Nationstar may also purchase loans out of a Ginnie Mae securitization pool if that loan meets certain criteria, including being delinquent greater than 90 days.
	Mortgage Loans Held for Investment, net (Level 3) – Nationstar determines the fair value of loans held for investment, net, using internally developed valuation models. These valuation models estimate the exit price Nationstar expects to receive in the loan’s principal market. Although Nationstar utilizes and gives priority to observable market inputs such as interest rates and market spreads within these models, Nationstar typically is required to utilize internal inputs, such as prepayment speeds and discount rates. These internal inputs require the use of judgment by Nationstar and can have a significant impact on the determination of the loan’s fair value. As these prices are derived from internally developed valuation, Nationstar classifies these valuations as Level 3 in the fair value disclosures.
	Mortgage Servicing Rights – Fair Value (Level 3) – Nationstar 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 various factors, with the key assumptions being mortgage prepayment speeds, discount rates, ancillary revenues and costs to service. 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 Nationstar 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, Nationstar classifies these valuations as Level 3 in the fair value disclosures.
	Reverse Mortgage Interests (Level 3) – Nationstar’s reverse mortgage interests consist of fees paid to taxing authorities for borrowers' unpaid taxes and insurance, and payments made to borrowers for line of credit draws on reverse mortgages. These interests are carried at lower of cost or market in the financial statements. Nationstar estimates the fair value using a market approach by utilizing the fair value of securities backed by similar reverse mortgage loans, adjusted for certain factors. As the adjustments to factors require the use of judgment, Nationstar classifies these valuations as Level 3 in the fair value disclosures.
	Derivative Financial Instruments (Level 2) – Nationstar enters into a variety of derivative financial instruments as part of its hedging strategy and measures these instruments at fair value on a recurring basis in the balance sheet. The majority of these derivatives are exchange-traded or traded within highly active dealer markets. In order to determine the fair value of these instruments, Nationstar utilizes the exchange price or dealer market price for the particular derivative contract; therefore, these contracts are classified as Level 2. In addition, Nationstar enters into IRLCs and LPCs with prospective borrowers and other loan originators. These commitments are carried at fair value based on the fair value of underlying mortgage loans which are based on observable market data. Nationstar adjusts the outstanding IRLCs with prospective borrowers based on an expectation that it will be exercised and the loan will be funded. IRLCs and LPCs are recorded in derivative financial instruments in the consolidated balance sheets. These commitments are classified as Level 2 in the fair value disclosures, as the valuations are based on market observable inputs. Nationstar has entered into Eurodollar futures contracts as part of its hedging strategy. The future contracts are measured at fair value on a recurring basis and classified as Level 2 in the fair value disclosures as the valuation is based on market observable data.
	Notes Payable (Level 2) – Notes payable consists of outstanding borrowings on Nationstar's warehouse and advance financing facilities. As the underlying warehouse and advance finance facilities bear interest at a rate that is periodically adjusted based on a market index, the carrying amount reported on the consolidated balance sheets approximates fair value. Nationstar previously classified these as Level 3; however, upon further consideration reclassified such amounts as Level 2 in current year principally because interest rates are tied directly to mark indices.
	Unsecured Senior Notes (Level 1) – The fair value of unsecured senior notes, which are carried at amortized cost, is based on quoted market prices and is considered Level 1 from the market observable inputs used to determine fair value.
	Nonrecourse Debt – Legacy Assets (Level 3) – Nationstar estimates fair value based on the present value of future expected discounted cash flows with the discount rate approximating current market value for similar financial instruments. These prices are derived from a combination of internally developed valuation models and quoted market prices, and are classified as Level 3.
	Excess Spread Financing (Level 3) – Nationstar estimates fair value on a recurring basis based on the present value of future expected discounted cash flows with the discount rate approximating current market value on a recurring basis for similar financial instruments. The cash flow assumptions and prepayment assumptions used in the model are based on various factors, with the key assumptions being mortgage prepayment speeds, average life, recapture rates and discount rate. Changes in fair value of the excess spread financing are recorded as a component of service related revenue in Nationstar's consolidated statements of income (loss) and comprehensive income (loss). As these prices are derived from a combination of internally developed valuation models and quoted market prices based on the value of the underlying MSRs, Nationstar classifies these valuations as Level 3 in the fair value disclosures.
	Mortgage Servicing Rights Financing Liability (Level 3) - Nationstar estimates fair value on a recurring basis based on the present value of future expected discounted cash flows with the discount rate approximating current market value on a recurring basis for similar financial instruments. The cash flow assumptions and prepayment assumptions used in the model are based on various factors, with the key assumptions being advance financing rates, annual advance recovery rates and working capital. Changes in fair value of the mortgage servicing rights financing liability are recorded as a component of service related revenues in Nationstar’s consolidated statements of income (loss) and comprehensive income (loss). As these prices are derived from a combination of internally developed valuation models and quoted market prices based on the value of the underlying MSRs.
	Participating Interest Financing (Level 2) – Nationstar estimates the fair value using a market approach by utilizing the fair value of securities backed by similar participating interests in reverse mortgage loans. Nationstar classifies these valuations as Level 2 in the fair value disclosures.
	2014-1 HECM Securitization (Level 3) – Nationstar estimates fair value of the non-recourse debt related to the 2014-1 HECM securitization based on the present value of future expected discounted cash flows with the discount rate approximating that of similar financial instruments. As the prices are derived from both internal models and other observable inputs, Nationstar classifies this as Level 3 in the fair value disclosures.

Mortgage Banking [Abstract]
Capital Requirements	Capital Requirements
	Certain of Nationstar'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, Nationstar's secondary market investors may utilize a range of remedies ranging from sanctions, suspension or ultimately termination of Nationstar's selling and servicing agreements, which would prohibit Nationstar from further originating or securitizing these specific types of mortgage loans or being an approved servicer.
	Among Nationstar's various capital requirements related to its outstanding selling and servicing agreements, the most restrictive of these requires Nationstar to maintain a minimum adjusted net worth balance of $1.0 billion. As of March 31, 2015, Nationstar was in compliance with its selling and servicing capital requirements.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies
	Litigation and Regulatory Matters
	Nationstar and its affiliates are routinely and currently involved in a significant number of legal proceedings concerning matters that arise in the ordinary course of business, including putative class actions and other litigation. These actions and proceedings are generally based on alleged violations of consumer protection, securities, employment, contract and other laws, including, without limitation, the Equal Credit Opportunity Act, Fair Debt Collection Practices Act, Fair Credit Reporting Act, Real Estate Settlement Procedures Act, Service members Civil Relief Act, Telephone Consumer Protection Act, Truth in Lending Act, Financial Institutions Reform, Recovery, and Enforcement Act of 1989 (FIRREA) and False Claims Act. Additionally, along with others in its industry, the Company is subject to repurchase and indemnification claims and may continue to receive claims in the future, relating to the sale of mortgage loans and/or the servicing of mortgage loans and 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 actual legal actions and proceedings include claims for substantial compensatory, punitive and/or statutory damages or claims for an indeterminate amount of damages. The outcome of such proceedings is difficult to predict or estimate until late in the proceedings, which may last several years. In particular, ongoing and other legal proceedings brought under federal or state consumer protection laws may result in a separate fine for each violation of the laws, which, particularly in the case of class action lawsuits, could result in damages substantially in excess of the amount earned from the underlying activities and that could have a material adverse effect on the Company's liquidity and financial position. The certification of any putative class action could substantially increase the Company's exposure to damages.
	Further, in the ordinary course of business the Company and its subsidiaries can be or are involved in governmental and regulatory examinations, information gathering requests, investigations and proceedings (both formal and informal), regarding the Company’s business, certain of which may result in adverse judgments, settlements, fines, penalties, injunctions or other relief. Such inquiries may include those into servicer foreclosure processes and procedures, lender-placed insurance and originations.
	The Company seeks to resolve all litigation and regulatory 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. On at least a quarterly basis, the Company assesses its liabilities and contingencies in connection with outstanding legal and regulatory 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 litigation or regulatory 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 estimable, the matter will continue to be monitored for further developments that would make such loss contingency both probable and estimable. Once the matter is deemed to be both probable and estimable, the Company will establish an accrued liability and record a corresponding amount to litigation 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. Litigation related expense, which includes the fees paid to external legal service providers, of $7.3 million for the three months ended March 31, 2015, and $4.9 million for the three months ended March 31, 2014, respectively, was included in general and administrative expenses on the consolidated statements of income (loss) and comprehensive income (loss).
	For a number of 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 litigation and regulatory matters on an ongoing basis, in conjunction with any outside counsel handling the matter. For those matters for which an estimate is possible, management currently believes the aggregate range of reasonably possible loss is $6.5 million to $18.1 million in excess of the accrued liability (if any) related to those matters as of March 31, 2015. This estimated range of possible loss is 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.
	Based on current knowledge, and after consultation with counsel, management believes that the current legal accrued liability is appropriate, and the amount of any incremental liability arising from these matters is not expected to have a material effect on the financial statements of the Company, although the outcome of such proceedings could be material to the Company’s financial statements 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 consolidated financial statements.
	Loan and Other Commitments
	Nationstar 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. Nationstar also enters into LPCs with prospective sellers. These loan commitments are treated as derivatives and are carried at fair value (See Note 7 - Derivative Financial Instruments).
	Nationstar has certain MSRs related to approximately $27.4 billion of unpaid principal balance in reverse mortgage loans. As servicer for these reverse mortgage loans, among other things, the Company is obligated to make advances to the loan customers as required. At March 31, 2015, the Company’s maximum unfunded advance obligation related to these MSRs was approximately $3.1 billion. Upon funding any portion of these advances, the Company expects to securitize and sell the advances in transactions that will be accounted for as a financing arrangement.

Segment Reporting [Abstract]
Business Segment Reporting	Business Segment Reporting
	Nationstar presents financial performance utilizing reportable segments aligned with how the operations are managed. The Servicing segment reflects the results of operations attributable to MSRs acquired from and loans subserviced for third-parties and originated loans. The Solutionstar segment reflects financial performance related to real estate services (e.g., collateral valuation, title, closing services) and real estate exchange, including our HomeSearch.comSM residential market portal. The Originations segment includes fees associated with loan originations and gains from the sale and securitization of loans. The Corporate and Other segment encompasses certain identified corporate costs as well as the 'Legacy' portfolio which includes primarily subprime mortgage loans originated in the latter portion of 2006 and 2007 or acquired from Nationstar's predecessor.
	Nationstar’s segments are based upon an organizational structure that focuses primarily on the services offered. The accounting policies of each reportable segment are the same as those of Nationstar except for 1) expenses for consolidated back-office operations and general overhead-type expenses such as executive administration and accounting, and 2) revenues generated on inter-segment services performed. Expenses are allocated to individual segments based on the estimated value of services performed, including estimated utilization of square footage and corporate personnel as well as the equity invested in each segment. Revenues generated on inter-segment services performed are valued based on similar services provided to external parties.
	To reconcile to Nationstar’s consolidated results, certain inter-segment revenues and expenses are eliminated in the “Eliminations” column in the following tables.
	The following tables are a presentation of financial information by segment for the periods indicated:

Related Party Transactions [Abstract]
Affiliates of Fortress Investment Group	Disclosures Related to Transactions with Affiliates of Fortress Investment Group LLC
	Springleaf Home Equity, Inc.
	Nationstar has several agreements to act as the loan subservicer for Springleaf Home Equity, Inc., formerly known as American General Home Equity, Inc., Springleaf General Financial Services of Arkansas, Inc., formerly known as American General Financial Services of Arkansas, Inc. and MorEquity, Inc. (collectively, Springleaf) totaling $1.9 billion in UPB for which Nationstar receives a monthly per loan subservicing fee and other performance incentive fees subject to the agreements with Springleaf. For the three months ended March 31, 2015 and March 31, 2014, Nationstar recognized revenue of $0.2 million and $2.0 million, respectively, in additional servicing and other performance incentive fees related to these portfolios. At March 31, 2015 and December 31, 2014, Nationstar had an outstanding receivable from Springleaf of $0.1 million and $0.2 million, respectively, which was included as a component of other assets.
	Newcastle Investment Corp. (Newcastle)
	Nationstar is the loan servicer for several securitized loan portfolios managed by Newcastle, which is managed by an affiliate of Fortress, for which Nationstar receives a monthly net servicing fee equal to 0.50% per annum on the unpaid principal balance of the portfolios, which was $0.7 billion and $0.8 billion, as of March 31, 2015 and December 31, 2014, respectively. For the three months ended March 31, 2015 and 2014, Nationstar received servicing fees and other performance incentive fees of $0.9 million and $1.1 million, respectively.
	New Residential Investment Corp. (New Residential)
	Excess Spread Financing
	Nationstar has entered into several agreements with certain entities formed by New Residential, in which New Residential and/or certain funds managed by Fortress own an interest (each a New Residential Entity), where Nationstar sold to the related New Residential Entity the right to receive a portion of the excess cash flow generated from certain acquired MSRs after receipt of a fixed basic servicing fee per loan. Nationstar retains the fixed base servicing fee, all ancillary revenues associated with servicing such MSRs and the retained portion of the excess servicing fee. Nationstar is the servicer of the loans and provides all servicing and advancing functions for the portfolio. The related New Residential Entity does not have prior or ongoing obligations associated with these MSR portfolios. Furthermore, should Nationstar refinance any loan in such portfolios, subject to certain limitations, Nationstar will be required to transfer the new loan or a replacement loan of similar economic characteristics into the portfolios. The new or replacement loan will be governed by the same terms set forth in the agreements described above.
	In addition, as of March 31, 2015, Nationstar has paid $27.5 million to New Residential for delinquent service fees in advance of the contractual due date. This amount will be ultimately netted against future remittances as related to service fee amounts. This amount is recorded as an offset to outstanding excess spread financing in our financial statements.
	The fair value on the outstanding liability related to these agreements was $1,047.6 million and $1,031.0 million at March 31, 2015 and December 31, 2014, respectively.
	Mortgage Servicing Rights Financing Liability
	In December 2013, Nationstar entered into a Master Servicing Rights Purchase Agreement and three related Sale Supplements (collectively, the Sale Agreement) with a joint venture entity (Purchaser) capitalized by New Residential in which New Residential and/or certain funds managed by Fortress own an interest. Under the Sale Agreement, Nationstar sold to the Purchaser the right to repayment on certain outstanding servicer advances outstanding on non-Agency mortgage loans. In addition, Nationstar also sold the right to receive the basic fee component on the related mortgage servicing rights, in exchange for the Purchaser remitting a portion of the basic fee to Nationstar in exchange for Nationstar continuing to service the mortgage loans. Nationstar will continue to act as named servicer under each servicing agreement until servicing is transferred to the Purchaser. Once the servicing is transferred under any servicing agreement to the Purchaser, Nationstar will subservice the applicable mortgage loans. While the transfer of the mortgage servicing rights to New Residential is intended to achieve the economic result of a sale of mortgage servicing rights, the Company accounts for the transactions as financings.
	The fair value of the outstanding liability related to the Sale Agreement was $45.0 million and $49.4 million at March 31, 2015 and December 31, 2014, respectively.
	As of March 31, 2015, Nationstar has transferred approximately $2.2 billion in servicer advances to the Purchaser in related supplemental agreements and received over $512.5 million in cash proceeds related to these transfers.
	Other
	In May 2014, Nationstar entered into a servicing arrangement with New Residential whereby Nationstar will service residential mortgage loans that New Residential and/or its various affiliates and trust entities acquire. The terms and fees of this servicing arrangement generally conform with industry standards for stand-alone residential mortgage loan servicing. For the three months ended March 31, 2015, Nationstar recognized revenue of $1.7 million related to these servicing arrangements.

Subsequent Events	. Subsequent Events
	Nationstar evaluated subsequent events through the date these consolidated financial statements were issued.
	In April 2015, Nationstar entered into a Master Repurchase Agreement with a financial institution, which will expire in April 2016. This facility has a committed amount of $200.0 million. The MRA states that from time to time, Nationstar may enter into transactions in which Nationstar agrees to transfer to the financial services company certain mortgage loans or MBS against the transfer of funds by the financial institution, with a simultaneous agreement by the financial institution to transfer such mortgage loans to Nationstar at a certain date, or on demand by Nationstar, against the transfer of funds by Nationstar. The interest rate is LIBOR plus a spread of 1.50% to 1.60% which varies based on the underlying transferred collateral.

Nature of Business and Basis of Presentation (Policies)	3 Months Ended
	Mar. 31, 2015
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation, Policy	The consolidated financial statements include the accounts of Nationstar, its wholly-owned subsidiaries, and other entities in which the Company has a controlling financial interest, and those variable interest entities (VIEs) where Nationstar's wholly-owned subsidiaries are the primary beneficiaries. Nationstar applies the equity method of accounting to investments when the entity is not a VIE and Nationstar is able to exercise significant influence, but not control, over the policies and procedures of the entity but owns less than 50% of the voting interests. Intercompany balances and transactions have been eliminated.
