Organization and Operations	Organization and Operations
	References to the terms “we”, “our”, “us”, “Stonegate” or the “Company” used throughout these Notes to Consolidated Financial Statements refer to Stonegate Mortgage Corporation and, unless the context otherwise requires, its wholly-owned subsidiaries. The Company was initially incorporated in the State of Indiana in January 2005. As a result of an acquisition and subsequent merger with Swain Mortgage Company ("Swain") in 2009, the Company is now an Ohio corporation. The Company’s headquarters is in Indianapolis, Indiana.
	The Company is a a specialty finance company that operates as an intermediary. It is focused on providing investment yield opportunities in the residential mortgage market to investors through originating, financing, and servicing U.S. residential mortgage loans. Since the date of the Company’s IPO, the Company has continued its development of internal management reporting. Such development has resulted in changes in the information that is provided to the Company’s chief operating decision maker. Accordingly, during the quarter ended September 30, 2014, management re-evaluated this information in relation to its definition of its operating segments. As a result of this new information provided to the chief operating decision maker, management has concluded that its Mortgage Banking operations should be disclosed as three segments: Originations, Servicing and Financing. Prior period segment disclosures have been restated to conform segment disclosures - see Note 20. This determination is based on the Company’s current organizational structure, which reflects the manner in which the chief operating decision maker evaluates the performance of the business.
	The Company’s integrated and scalable residential mortgage banking platform includes a diversified origination business which includes a retail branch network, a direct to consumer call center and a network of third party originators consisting of mortgage brokers, mortgage bankers and financial institutions (banks and credit unions). The Company predominantly sells mortgage loans to the Federal National Mortgage Association (“Fannie Mae” or “FNMA”), the Federal Home Loan Mortgage Corporation (“Freddie Mac” or “FHLMC”), financial institution secondary market investors and the Government National Mortgage Association (“Ginnie Mae” or “GNMA”) as pools of mortgage backed securities (“MBS”). Both FNMA and FHLMC are considered government-sponsored enterprises ("GSEs"). The Company also provides warehouse financing through its NattyMac, LLC subsidiary to third party correspondent lenders. The Company’s principal sources of revenue include (i) gains on sales of mortgage loans from loan securitizations and whole loan sales and fee income from originations, (ii) fee income from loan servicing, and (iii) fee and net interest income from its financing facilities and warehouse lending business.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies
	Basis of Presentation: The accompanying consolidated financial statements include the accounts of Stonegate and its subsidiaries and have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) and in accordance with the instructions to Form 10-K as promulgated by the Securities and Exchange Commission. All intercompany accounts and transactions have been eliminated in consolidation.
	Use of Estimates: The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in the Company’s consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly significant relate to the Company’s fair value measurements of mortgage loans held for sale, mortgage servicing rights (“MSRs”), derivative assets and liabilities, goodwill and other intangible assets, as well as its estimates for the reserve for mortgage repurchases and indemnifications and income tax estimates for deferred tax assets valuation allowance considerations.
	Risks and Uncertainties: In the normal course of business, companies in the mortgage banking industry encounter certain economic and regulatory risks. Economic risks include interest rate risk and credit risk. In a declining interest rate environment, the Company's mortgage origination activities’ results of operations could be positively impacted by higher loan origination volumes and loan margins. In contrast, the Company's results of operations of its mortgage servicing activities could decline due to higher actual and projected loan prepayments related to its loan servicing portfolio. In a rising interest rate environment, the Company's mortgage origination activities' results of operations could be negatively impacted and its mortgage servicing activities’ results of operations to be positively impacted. Credit risk is the risk of default that may result from the borrowers’ inability or unwillingness to make contractually required payments during the period in which loans are being held for sale. The Company manages these various risks through a variety of policies and procedures, such as the hedging of the loans held for sale and interest rate lock commitments using forward sales of MBS, such as To Be Announced (“TBA”) securities, designed to quantify and mitigate the operational and financial risk to the Company to the extent possible. Specifically, the Company engages in hedging of interest rate risk of its mortgage loans held for sale and interest rate lock commitments with the use of TBA securities.
	The Company sells loans to investors without recourse. As such, the investors have assumed the risk of loss or default by the borrower. However, the Company is usually required by these investors to make certain standard representations and warranties relating to credit information, loan documentation and collateral. To the extent that the Company does not comply with such representations, the Company may be required to repurchase the loans or indemnify these investors for any losses from borrower defaults. The Company performs due diligence prior to funding mortgage loans as part of its loan underwriting process, whereby the Company analyzes credit, collateral and compliance risk of all loans in an effort to ensure the mortgage loans the investors’ standards. However, if a loan is repurchased, the Company could incur a loss as part of recording such loan at fair value, which may be less than the amount paid to purchase the loan. In addition, if loans pay off within a specified time frame, the Company may be required to refund a portion of the sales proceeds to the investors.
	The Company’s business requires substantial cash to support its operating activities. As a result, the Company is dependent on its lines of credit and other financing facilities in order to finance its continued operations. If the Company’s principal lenders decided to terminate or not to renew any of these credit facilities with the Company, the loss of borrowing capacity would have a material adverse impact on the Company’s financial statements unless the Company found a suitable alternative source of financing.
	Consolidation: The Company’s loans held for sale are sold predominantly to FNMA. The Company also sells loans in GNMA guaranteed mortgage-backed securities (“MBS”) by pooling eligible loans through a pool custodian and assigning rights to the loans to GNMA. FNMA and GNMA provide credit enhancement of the loans through certain guarantee provisions. These securitizations involve variable interest entities (“VIEs”) as the trusts or similar vehicles, by design, that either (1) lack sufficient equity to permit the entity to finance its activities without additional subordinated financial support from other parties, or (2) have equity investors that do not have the ability to make significant decisions relating to the entity’s operations through voting rights, or do not have the obligation to absorb the expected losses, or do not have the right to receive the residual returns of the entity.
	The primary beneficiary of a VIE (i.e., the party that has a controlling financial interest) is required to consolidate the assets and liabilities of the VIE. The primary beneficiary is the party that has both (1) the power to direct the activities of an entity that most significantly impact the VIE’s economic performance; and (2) through its interests in the VIE, the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. The Company typically retains the right to service the loans. Because of the power of FNMA and GNMA over the VIEs that hold the assets from these residential mortgage loan securitizations, principally through its rights and responsibilities as master servicer for FNMA and as approver of issuers for GNMA and the guarantee provisions provided by FNMA and GNMA, the Company is not the primary beneficiary of the VIEs and therefore the VIEs are not consolidated by the Company.
	The Company has concluded that on a consolidated basis it has a variable interest in NattyMac Funding ("NMF") resulting from any potential interest it may earn from the 49% NMF earnings participation, as described in Note 12, "Debt".  The Company has further concluded that it is not considered the primary beneficiary of its variable interest in NMF based on the fact that  it does not have the power to direct the activities of NMF that most significantly impact NMF’s economic performance.  NMF has the final authority over its operating policies.  If at any time in the future the Company claims the right to the common capital stock of NMF in a default scenario as described, the primary beneficiary conclusion may change.  The Company believes that its maximum exposure to loss as a result of this arrangement is the $30,000 in subordinated loan receivable as of December 31, 2014.
	The Company performs on-going reassessments of: (1) whether entities previously evaluated under the majority voting-interest framework have become VIEs, based on certain events, and therefore become subject to the VIE consolidation framework; and (2) whether changes in the facts and circumstances regarding the Company’s involvement with a VIE cause the Company’s consolidation determination to change.
	Revenue Recognition:
	Mortgage Loans Held for Sale: Loan originations that are intended to be sold in the foreseeable future, including residential mortgages, are reported as mortgage loans held for sale. Mortgage loans held for sale are carried at fair value under the fair value option with changes in fair value recognized in current period earnings. At the date of funding of the mortgage loan held for sale, the funded amount of the loan, the related derivative asset or liability of the associated interest rate lock commitment, less direct loan costs (including but not limited to correspondent fees, broker premiums and underwriting expenses) becomes the initial recorded investment in the mortgage loan held for sale. Such amount approximates the fair value of the loan.
	Mortgage loans held for sale are considered de-recognized, or sold, when the Company surrenders control over the financial assets. Control is considered to have been surrendered when the transferred assets have been isolated from the Company, beyond the reach of the Company and its creditors; the purchaser obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets; and the Company does not maintain effective control over the transferred assets through an agreement that both entitles and obligates the Company to repurchase or redeem the transferred assets before their maturity or the ability to unilaterally cause the holder to return specific assets. Such transfers may involve securitizations, participation agreements or repurchase agreements. If the criteria above are not met, such transfers are accounted for as secured borrowings, in which the assets remain on the balance sheet, the proceeds from the transaction are recognized as a liability and no MSRs are recorded for those transferred loans.
	Gains and losses from the sale of mortgages are recognized based upon the difference between the sales proceeds and carrying value of the related loans upon sale and is recorded in gains on mortgage loans held for sale in the statement of operations. The sales proceeds reflect the cash received and the initial fair value of the separately recognized mortgage servicing rights less the fair value of the liability for mortgage repurchases and indemnifications. Gain on mortgage loans held for sale also includes the unrealized gains and losses associated with the mortgage loans held for sale and the realized and unrealized gains and losses from derivatives.
	Sale of Mortgage Servicing Rights: The Company occasionally sells a certain portion of its MSRs. At the time of the sale, based on the structure of the arrangement, the Company typically records a gain or loss on such sale based on the selling price of the MSRs less the carrying value and transaction costs. The MSRs are sold in separate transactions from the sale of the underlying loans. The MSRs sales are assessed to determine if they qualify as a sale transaction. A transfer of servicing rights related to loans previously sold qualifies as a sale at the date on which title passes, if substantially all risks and rewards of ownership have irrevocably passed to the transferee and any protection provisions retained by the transferor are minor and can be reasonably estimated. In addition, if a sale is recognized and only minor protection provisions exist, a liability should be accrued for the estimated obligation associated with those provisions. As MSRs are not considered financial assets for accounting purposes, the accounting model used to determine if the transfer of an MSRs asset qualifies as a sale is based on a risks and rewards approach. Upon completion of a sale, the Company would account for the transaction as a sale and derecognize the mortgage servicing rights from the Consolidated Balance Sheets.
	Mortgage Servicing Rights and Change in Mortgage Servicing Rights Valuation: The Company capitalizes MSRs at fair value when purchased or at the time the underlying loans are de-recognized, or sold, and when the Company retains the right to service such loans. To determine the fair value of the MSRs, the Company uses a valuation model that calculates the present value of future cash flows from servicing. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, including estimates of the cost of servicing, the discount rate, float value, the inflation rate, estimated prepayment speeds, and default rates. MSRs currently are not actively traded in the markets, accordingly, considerable judgment is required to estimate their fair value and the exercise of that judgment can materially impact current period earnings.
	For periods prior to January 1, 2013, the Company accounted for the subsequent measurement of its MSRs at the lower of amortized cost or fair value. Effective January 1, 2013, the Company elected to irrevocably account for the subsequent measurement of its existing MSRs using the fair value method, whereby the subsequent changes in the fair value of the MSRs are recorded in earnings during the period in which the changes occur. Under the fair value method, the fair value of the Company's originated mortgage loans class of MSRs is assessed at each reporting date using the methods described above. In accordance with the applicable GAAP guidance, this change in accounting principle was accounted for on a prospective basis (financial statement periods prior to 2013 were not restated). The Company did not record a cumulative-effect adjustment to retained earnings as of January 1, 2013, as the net amortized carrying value of the MSRs as of January 1, 2013 equaled the fair value at such date due to MSRs impairment charges recorded during 2012.
	Loan Origination and Other Loan Fees: Loan origination and other loan fee income represents revenue earned from originating mortgage loans. Loan origination and other loan fees generally represent flat, per-loan fee amounts and are recognized as revenue, net of loan origination costs (excluding those direct loan origination costs that are recorded as a component of the recorded investment in mortgage loans held for sale), at the time the loans are funded.
	Loan Servicing Fees: Loan servicing fee income represents revenue earned for servicing mortgage loans. The servicing fees are based on a contractual percentage of the outstanding principal balance and recognized as revenue as the related mortgage payments are collected. Corresponding loan servicing costs are charged to expense as incurred.
	Interest Income: Interest income on mortgage loans is accrued to income based upon the principal amount outstanding and contractual interest rates. Income recognition is discontinued when loans become 90 days delinquent or when in management’s opinion, the collectability of principal and income becomes doubtful.
	Warehouse Lending Receivables: During the year ended December 31, 2013, the Company introduced its warehouse lending products to its correspondent customers through warehouse line of credit agreements. Under the warehouse line of credit agreements, the Company lends funds to its correspondent customers to finance those correspondents' mortgage loan originations. The correspondent customers pledge, as security to the Company, the underlying mortgage loans, and pay interest on the related outstanding borrowings at a specified interest rate plus a margin, as defined in the underlying line of credit agreements with each correspondent customer. As of December 31, 2014, the Company had outstanding warehouse lending receivables from its correspondent customers of $85,431 and recognized interest income from its warehouse lending activities of $2,812 during the year ended December 31, 2014. As of December 31, 2013, the Company had outstanding warehouse lending receivables from its correspondent customers of $12,089 and recognized interest income from its warehouse lending activities of $92 during the year ended December 31, 2013. The Company periodically reviews the counterparties and warehouse lending receivables for collectability based on historical collection trends and management judgment regarding the ability to collect specific accounts and has determined that no allowance for doubtful accounts was necessary as of December 31, 2014 or December 31, 2013.
	Derivative Financial Instruments: All derivative financial instruments are recognized as either assets or liabilities and measured at fair value. The Company accounts for all of its derivatives as free-standing derivatives and does not designate any for hedge accounting. Therefore, the gain or loss resulting from the change in the fair value of the derivative is recognized in the Company’s results of operations during the period of change.
	The Company enters into commitments to originate residential mortgage loans held for sale, at specified interest rates and within a specified period of time, with customers who have applied for a loan and meet certain credit and underwriting criteria (interest rate lock commitments). These interest rate lock commitments (“IRLCs”) meet the definition of a derivative financial instrument and are reflected in the balance sheet at fair value with changes in fair value recognized in current period earnings. Unrealized gains and losses on the IRLCs are recorded as derivative assets and derivative liabilities, respectively, and are measured based on the value of the underlying mortgage loan, quoted MBS prices, estimates of the fair value of the mortgage servicing rights and the probability that the mortgage loan will fund within the terms of the interest rate lock commitment, net of estimated commission expenses.
	The Company manages the interest rate and price risk associated with its outstanding IRLCs and loans held for sale by entering into derivative instruments such as forward loan sales commitments and mandatory delivery commitments. Management expects these derivatives will experience changes in fair value opposite to changes in fair value of the IRLCs and loans held for sale, thereby reducing earnings volatility. The Company takes into account various factors and strategies in determining the portion of the mortgage pipeline (IRLCs) and loans held for sale it wants to economically hedge.
	Reserve for Loan Repurchases and Indemnifications: Loans sold to investors by the Company and which met investor and agency underwriting guidelines at the time of sale may be subject to repurchase or indemnification in the event of specific default by the borrower or subsequent discovery that underwriting standards were not met. The Company may, upon mutual agreement, agree to repurchase the loans or indemnify the investor against future losses on such loans. In such cases, the Company bears any subsequent credit loss on the loans. The Company has established an initial reserve liability for expected losses related to these representations and warranties at the date the loans are de-recognized from the balance sheet based on the fair value of such reserve liability. Subsequently, based on changing facts and circumstances or changes in certain estimates and assumptions, the reserve liability is adjusted with a corresponding amount recorded to provision for reserve for mortgage repurchases and indemnifications. In assessing the adequacy of the reserve, management evaluates various factors including actual losses on repurchases and indemnifications during the period, historical loss experience, known delinquent and other problem loans, delinquency trends in the portfolio of sold loans and economic trends and conditions in the industry. Actual losses incurred are reflected as charge-offs against the reserve liability.
	Loans Eligible for Repurchase from GNMA: When the Company has the unilateral right to repurchase GNMA pool loans it has previously sold (generally loans that are more than 90 days past due), the Company then records the loan on its balance sheet. The recognition of previously sold loans does not impact the accounting for the previously recognized mortgage servicing rights.
	Servicing Advances: Servicing advances represent escrows and advances paid by the Company on behalf of customers and investors to cover delinquent balances for property taxes, insurance premiums and other out-of-pocket costs. Advances are made in accordance with the servicing agreements and are recoverable upon collection of future borrower payments or foreclosure of the underlying loans. The Company periodically reviews these receivables for collectability and amounts are written off when they are deemed uncollectible. As of December 31, 2014 and 2013, the Company had recognized an asset for servicing advances on its consolidated balance sheet of $11,193 and $4,177, respectively.
	Property and Equipment: Property and equipment is recorded at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over estimated useful lives of one to three years for internally developed computer software, three to ten years for furniture and equipment and three to five years for purchased computer software and equipment. Leasehold improvements are amortized using the straight-line method over the shorter of the related lease term or their estimated economic useful lives.
	The Company periodically assesses property and equipment for recoverability whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. If management identifies an impairment indicator, it assesses recoverability by comparing the carrying amount of the asset to the undiscounted cash flows expected to result from the use and eventual disposition of the asset. An impairment loss is recognized in earnings whenever the carrying amount is not recoverable. No such impairments were recognized during the years ended December 31, 2014, 2013 and 2012.
	Goodwill and Other Intangible Assets: Business combinations are accounted for using the acquisition method of accounting. Acquired intangible assets are recognized and reported separately from goodwill. Goodwill represents the excess cost of acquisition over the fair value of net assets acquired. Finite-lived purchased intangible assets consist of the Crossline trade name, customer relationships, non-compete agreement, an active agent list and state licenses, which have useful lives of four years, eight years, three years, five years and one year, respectively. Intangible assets with finite lives are amortized over their estimated lives using an amortization method that reflects the pattern in which the economic benefits of the asset are consumed. The Company evaluates the estimated remaining useful lives on intangible assets to determine whether events or changes in circumstances warrant a revision to the remaining periods of amortization. If an intangible asset’s estimated useful life is changed, the remaining net carrying amount of the intangible asset is amortized prospectively over that revised remaining useful life. Additionally, an intangible asset that initially is deemed to have a finite useful life would cease being amortized if it is subsequently determined to have an indefinite useful life. Such intangible assets are then tested for impairment. The Company reviews such intangibles for impairment whenever events or changes in circumstances indicate their carrying amounts may not be recoverable, in which case any impairment charge would be recorded to earnings. Given the formation of Stonegate Direct in October 2014, which was integrated through the call center operations of Crossline, the Company determined there was a significant change in the manner in which the Crossline trade name was used and as a result determined the change to be a triggering event for an impairment analysis to be performed in accordance with the guidance of long-lived assets. As of December 31, 2014, the Crossline trade name had no carrying value on its Consolidated Balance Sheet.
	Indefinite-lived purchased intangible assets consist of the NattyMac trade name. Goodwill and other intangible assets with an indefinite useful life are not subject to amortization but are reviewed for impairment annually or more frequently whenever events or changes in circumstances indicate that the carrying amount of an intangible asset may not be recoverable. For indefinite-lived intangible assets other than goodwill, the Company first assesses qualitative factors to determine whether the existence of events or circumstances leads to a determination that is more likely than not the assets are impaired. If the Company determines that it is more likely than not that the intangible assets are impaired, a quantitative impairment test is performed. For the quantitative impairment test, the Company estimates and compares the fair value of indefinite-lived intangible asset with its carrying amount. If the carrying amount of the indefinite-lived intangible asset exceeds its fair value, the amount of the impairment is measured as the difference between the carrying amount of the asset and its fair value. Impairment is permanently recognized by writing down the asset to the extent that the carrying value exceeds the estimated fair value.
	For goodwill, the Company first performs a quantitative impairment test. At the operating segment level, which is the reporting unit, the Company estimates and compares the fair value to the book value. If the segment's book value exceeds its fair value, the Company then performs a hypothetical purchase price allocation for the segment. This is done by marking all assets and liabilities to fair value and calculating an implied goodwill value. If the implied goodwill value is less than the carrying value of the goodwill, the amount of impairment is measured as the difference and is permanently recognized by writing down the goodwill to the extent the carrying value exceeds the implied value. No impairment has been recognized on our goodwill and other intangible assets during the years ended December 31, 2014, 2013 and 2012.
	Stock Split: On May 14, 2013, the Company granted a stock dividend of 12.861519 shares of common stock for each share of common stock held as of that date, which was determined to be in substance a stock split for accounting and financial reporting purposes. All actual share, weighted-average share and per share amounts and all references to stock compensation data and prices of the Company’s common stock have been adjusted to reflect this stock split for all periods presented.
	Stock-Based Compensation: The Company grants stock options and restricted stock units to certain executive officers, key employees and independent directors. Stock options have been granted for a fixed number of shares with an exercise price at least equal to the fair value of the shares at the date of grant. Restricted stock units have been granted for a fixed number of shares with a fair value equal to the fair value of the Company's common stock on the grant date. The stock options and restricted stock units granted are recognized as compensation expense in the statement of operations based on their grant-date fair values.
	Advertising and Marketing: The Company uses primarily print, broadcast and web-based advertising and marketing to promote its products. Advertising and marketing is expensed as incurred and totaled $3,216, $2,317 and $1,059 for the years ended December 31, 2014, 2013 and 2012.
	Income Taxes: Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. There was no such need for a valuation allowance as of December 31, 2014 and 2013. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.
	The Company’s income tax expense includes assessments related to uncertain tax positions taken or expected to be taken by the Company. Management has concluded that it currently does not have any significant uncertain tax positions. If applicable, the Company will recognize interest and penalties related to unrecognized tax benefits as a component of income tax expense. The open tax years subject to examination by taxing authorities include the years ended December 31, 2013, 2012 and 2011. The Company had no federal or state tax examinations in process as of December 31, 2014.
	Cash and Cash Equivalents: The Company classifies cash and temporary investments with original maturities of three months or less as cash and cash equivalents, which totaled $45,382 and $43,104 at December 31, 2014 and 2013, respectively. The Company typically maintains cash in financial institutions in excess of FDIC limits. The Company evaluates the creditworthiness of these financial institutions in determining the risk associated with these cash balances.
	Restricted Cash: The Company maintains certain cash balances that are restricted under broker margin account agreements associated with its derivative activities.
	Recent Accounting Developments: ASU No. 2014-04, "Receivables--Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans Upon Foreclosure," was issued in January 2014. This update clarifies when a creditor is considered to have received physical possession of residential real estate property collateralized by a consumer mortgage loan in order to reduce diversity in practice for when a creditor derecognizes the loan receivable and recognizes the real estate property. The guidance in ASU No. 2014-04 also requires interim and annual disclosure of the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure. The new guidance will be effective for the Company beginning on January 1, 2015. The Company does not expect the adoption of the new guidance to have a material impact on its financial statements.
	ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)" was issued in May 2014. This update supersedes the revenue recognition criteria and amends existing requirements in other Topics to be consistent with the new recognition and measurement rules. This update is to ensure that an entity is recognizing revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new guidance will be effective for the Company beginning on January 1, 2017. The Company is currently evaluating the guidance under ASU 2014-09 and has not yet determined the impact, if any, on its consolidated financial statements.
	ASU No. 2014-11, "Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures," was issued in June 2014. The pronouncement in this update changes the accounting for repurchase-to-maturity transactions and linked repurchase financings to secured borrowing accounting, which is consistent with the accounting for other repurchase agreements. The pronouncement also requires two new disclosures. The first disclosure requires an entity to disclose information on transfers accounted for as sales in transactions that are economically similar to repurchase agreements. The second disclosure provides increased transparency about the types of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. The new guidance will be effective for the Company beginning on January 1, 2015. The Company does not expect the adoption of the new guidance to have a material impact on its financial statements.
	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" was issued in June 2014. This update addresses how entities commonly issue share-based payment awards that require a specific performance target to be achieved in order for employees to become eligible to vest in the awards. Current US GAAP does not contain explicit guidance on how to account for those share-based payments. This update is intended to resolve the diverse accounting treatment of those awards in practice. The new guidance will be effective for the Company beginning on January 1, 2015. The Company does not expect the adoption of the new guidance to have a material impact on its financial statements.
	ASU No. 2014-14, "Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40) -Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure" was issued in August 2014. This update requires certain government-guaranteed mortgage loans to be reclassified to a separate other receivable at the time of foreclosure. The new guidance will be effective for the Company beginning on January 1, 2015. The Company does not expect the adoption of the new guidance to have a material impact on its financial statements.
	ASU No. 2014-15, "Presentation of Financial Statements - Going Concern (Topic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern" was issued in August 2014. This update is intended to define management's responsibility to evaluate whether there is a substantial doubt about an organization's ability to continue as a going concern and to provide related footnote disclosure. The new guidance will be effective for the Company beginning on January 1, 2016. The Company does not expect the adoption of the new guidance to have a material impact on its financial statements.
	ASU No. 2014-17, "Business Combinations (Topic 805) - Pushdown Accounting" was issued in November 2014. This update provides an acquired entity with an option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. An acquired entity may elect the option to apply pushdown accounting in the reporting period in which the change-in-control events occurs. The new guidance will be effective for the Company on the date of its next business combination. The Company does not expect the adoption of the new guidance to have a material impact on its financial statements.
	ASU No. 2015-02, "Consolidation (Topic 810) - Amendments to the Consolidation Analysis" was issued in February 2015. This update affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. The amendments in this update affect the following areas: 1) limited partnerships and similar legal entities, 2) evaluating fees paid to a decision maker or a service provider as a variable interest, 3) the effect of fee arrangements on the primary beneficiary determination, 4) the effect of related parties on the primary beneficiary determination, and 5) certain investment funds. The new guidance will be effective for the Company beginning on January 1, 2016. The Company does not expect the adoption of the new guidance to have a material impact on its financial statements.
	Prior Period Reclassifications: Certain prior period amounts have been reclassified to conform to the current period presentation.

Business Combinations [Abstract]
Business Combinations	Business Combinations
	Acquisition of Medallion Mortgage Company
	On February 4, 2014, in the continuing effort to expand retail originations, the Company completed its acquisition of Medallion Mortgage Company ("Medallion"), a residential mortgage originator based in southern California. Medallion services customers with an extensive portfolio of residential real estate loan programs and has 10 offices along the southern and central coast of California, Utah and a new operations center in Ventura, California. In the acquisition of Medallion, the Company agreed to purchase certain assets, assume certain liabilities and offer employment to certain employees.
	The acquisition of Medallion was accounted for as a business combination. The following table summarizes the total consideration transferred to acquire Medallion and the fair values of the assets acquired and liabilities assumed on the acquisition date:
	Consideration:
	Cash consideration	$	258
	Fair value of contingent consideration	603
	Total consideration	861
	Fair value of net assets acquired:
	Property and equipment	190
	Other assets	94
	Accounts payable and accrued expenses	(50		)
	Total fair value of net assets acquired	234
	Goodwill	$	627
	Acquisition-related expenses 1	$	49
	1 Legal and miscellaneous expenses classified as general and administrative expenses.
	The excess of the aggregate consideration transferred over the fair value of the identified net assets acquired resulted in tax-deductible goodwill of $627 as of December 31, 2014. Goodwill recognized from the acquisition of Medallion primarily relates to the expected future growth of Medallion's business.
	As part of the acquisition of Medallion, the Company agreed to pay Medallion's seller a deferred purchase price, which payment is contingent upon Medallion achieving certain predetermined minimum mortgage loan origination goals during the two year period following the acquisition date (the "earnout"). If such goals are met by Medallion, the Company will pay the seller annual payments equal to a multiple of the actual total mortgage loan volume of Medallion. The earnout is uncapped in amount. The fair value of the earnout was estimated to be approximately $603 as of the acquisition date and was estimated using a calibrated Monte-Carlo simulation. The fair value was primarily based on (i) the Company’s estimate of the mortgage loan origination volume of Medallion over the two year earnout period, (ii) an asset volatility factor of 16.90% and (iii) a discount rate of 6.05%. The Company estimated the fair value of the earnout as of December 31, 2014 using the calibrated Monte-Carlo simulation and determined to decrease the estimate by $153, which is recorded within "General and administrative expense" on the Company's consolidated statement of operations, for the year ended December 31, 2014.
	Acquisition of Crossline Capital, Inc.
	On December 19, 2013, the Company completed its acquisition of Crossline Capital, Inc. ("Crossline"), a California-based mortgage lender that originates, funds, and services residential mortgages. The acquisition of Crossline allowed the Company to increase its origination volume through geographic expansion. At the time of the acquisition, Crossline was licensed to originate mortgages in 20 states including Arizona, California, Colorado, Connecticut, Florida, Georgia, Idaho, Maryland, Massachusetts, New Hampshire, New Mexico, North Carolina, Ohio, Oregon, Pennsylvania, Rhode Island, Texas, Utah, Virginia and Washington, and is an approved FNMA Seller Servicer. In addition, it operated two national mortgage origination call centers in Lake Forest, CA and Scottsdale, AZ and also operated retail mortgage origination branches in seven other locations in Southern California.
	The following table summarizes the total consideration transferred to acquire Crossline and the fair values of assets acquired and liabilities assumed on the acquisition date:
	Consideration:
	Cash consideration	$	9,765
	Fair value of contingent consideration	1,706
	Total consideration	11,471
	Fair value of assets acquired:
	Cash and cash equivalents (including restricted cash)	3,688
	Mortgage loans held for sale	28,394
	Identified intangible assets	2,204
	MSRs	344
	Other assets	2,378
	Total fair value of assets acquired	37,008
	Fair value of liabilities assumed:
	Warehouse lines of credit	27,454
	Other liabilities	1,676
	Total fair value of liabilities assumed	29,130
	Fair value of net assets acquired	7,878
	Goodwill	$	3,593
	Acquisition-related expenses	$	122
	The excess of the aggregate consideration transferred over the fair value of the identified net assets acquired resulted in tax-deductible goodwill of $3,593 as of December 31, 2014. Goodwill recognized from the acquisition of Crossline primarily relates to the expected future growth of Crossline's business and future economic benefits arising from expected synergies.
	As part of the acquisition of Crossline, the Company agreed to pay Crossline's seller a deferred purchase price, which payment is contingent upon the seller meeting certain conditions. The first contingent payment is conditional upon the following: during the six month period following the acquisition, the seller must sign letters of intent with at least two mortgage loan origination businesses who employ at least five licensed mortgage loan originators and whose total mortgage loan origination volume during the prior twelve month period was at least $50,000 in aggregate unpaid principal balance. If such conditions are met, the seller will be due a payment equal to a multiple of the actual total mortgage loan volume of Crossline during such six month period, not to exceed $500 (the "on-boarding payment"). The potential undiscounted amount of the on-boarding payment that the Company could be required to make under this contingent consideration arrangement is between $0 and $500. The fair value of the on-boarding payment was estimated to be approximately $307 as of December 31, 2013 and was estimated by applying the income approach. The fair value was primarily based on (i) the Company’s estimate of the number of mortgage loan originators that will become employed by Stonegate and the expected mortgage loan origination volume over the six month on-boarding period and (ii) a discount rate of 6.50%.
	In addition, the Company agreed to pay Crossline's seller a second contingent payment that is conditional upon Crossline achieving certain predetermined minimum mortgage loan origination goals during the two year period following the acquisition date (the "earnout"). If such goals are met by Crossline, the Company will pay the seller quarterly payments equal to a multiple of the actual total mortgage loan volume of Crossline. The earnout is uncapped in amount. The fair value of the earnout was estimated to be approximately $1,399 as of December 31, 2013 and was estimated using a calibrated Monte-Carlo simulation. The fair value was primarily based on (i) the Company’s estimate of the mortgage loan origination volume of Crossline over the two year earnout period, (ii) an asset volatility factor of 18.70% and (iii) a discount rate of 6.50%.
	For the year ended December 31, 2014, the Company adjusted its earn-out liability for Crossline by an increase of $110. Effective September 30, 2014, the Company amended the agreement governing the earnout provisions related to the acquisition of Crossline. As a result of the amendment, the remaining earnout amount to be paid to the original seller was fixed and is no longer contingent.
	Of the $2,204 of total acquired intangible assets, $380 was assigned to a non-compete agreement with the seller of Crossline, which has an estimated life of three years, and $104 was assigned to state licenses, which have an estimated life of one year. The trade name was assigned $1,720, which was assigned an estimated life of four years. Given the formation of Stonegate Direct in October 2014, which was integrated through the call center operations of Crossline, the Company determined there was a significant change in the manner in which the Crossline trade name was used and as a result determined the change to be a triggering event for an impairment analysis to be performed in accordance with the guidance of long-lived assets. As of December 31, 2014, the Crossline trade name had no carrying value on its Consolidated Balance Sheet. The Company did not recognize any amortization expense related to the definite-lived intangible assets acquired from Crossline during the year ended December 31, 2013 due to the short period of time the assets were held between the acquisition date (December 19, 2013) and December 31, 2013.
	Acquisition of Wholesale Channel and Retail Assets from Nationstar Mortgage Holdings, Inc.
	On November 29, 2013, the Company completed its acquisition of the wholesale lending channel and certain distributed retail assets of Nationstar Mortgage Holdings Inc. ("Nationstar"). The acquisition of Nationstar's wholesale lending channel and retail assets will complement the Company's existing wholesale and retail channels and accelerate its geographic expansion. Pursuant to the terms of the letter of intent, the Company agreed to purchase the assets and offer employment to certain employees associated with these businesses.
	The acquisition of Nationstar's assets was accounted for as a business combination. The Company paid $484, for the assets acquired, which consisted primarily of property and equipment that had a total estimated fair value of $484 at the acquisition date, resulting in no goodwill or bargain purchase gain during the year ended December 31, 2013. Acquisition costs related to the assets acquired from Nationstar totaled $24 during the year ended December 31, 2013.
	Acquisition of Assets from NattyMac, LLC
	On August 30, 2012, the Company acquired all rights, title and interest in the assets of the NattyMac, LLC ("NattyMac") single-family mortgage loan warehousing business. Founded in 1994 in St. Petersburg, FL, NattyMac operated as an independent mortgage warehouse lender focused on financing prime mortgage loans that were committed for purchase by GSEs. NattyMac’s strong reputation in the mortgage banking industry, along with its warehouse financing platform and experienced staff, complements the Company’s existing business and allows the Company to provide an additional source of funding to its customers.
	The following table summarizes the total consideration transferred for NattyMac and the fair value of assets acquired on the acquisition date:
	Consideration:
	Cash consideration	$	512

	Total fair value of assets acquired	3,779
	Bargain purchase gain	$	1,172
	Acquisition-related expenses	$	406
	The acquisition of NattyMac’s assets was determined to be a bargain purchase, as the fair value of the identified assets acquired exceeded the aggregate consideration transferred. Accordingly, the Company recognized a bargain purchase gain which is classified as “Other revenue” in its consolidated results of operations for the twelve months ended December 31, 2012.
	As part of the acquisition of the assets of NattyMac, the Company agreed to pay NattyMac’s sellers a deferred purchase price of $75 (whole dollars) for each mortgage loan funded through the mortgage loan warehousing business acquired from NattyMac. The potential undiscounted amount of all future payments that the Company could be required to make under the contingent consideration arrangement is between $0 and $2,250. There is no expiration date for the fulfillment of the contingent consideration arrangement. The fair value of the contingent consideration arrangement was estimated to be approximately $1,832 and $2,085 as of December 31, 2014 and December 31, 2013, respectively, and was estimated by applying the income approach. The fair value of the contingent consideration as of December 31, 2014 and December 31, 2013 was based on key assumptions including (i) the Company’s estimate of the number and timing of mortgage loans to be funded and (ii) discount rates of 6.50% and 5.37%, respectively. The Company’s revised estimated fair value of the contingent earn-out liability of $1,832 as of December 31, 2014 decreased from its original acquisition-date estimated fair value of $2,095 primarily due to the estimated timing of mortgage loan fundings from the NattyMac warehousing business as well as cash payments. At December 31, 2014, 5,622 mortgage loans had been funded through NattyMac’s single-family warehousing business and the Company expects that the full amount of contingent consideration will be paid over a three-year period.

	The Company has exposure to credit loss in the event of contractual non-performance by its trading counterparties and counterparties to the over-the-counter derivative financial instruments that the Company uses in its interest rate risk management activities. The Company manages this credit risk by selecting only counterparties that the Company believes to be financially strong, spreading the credit risk among many such counterparties, by placing contractual limits on the amount of unsecured credit extended to any single counterparty and by entering into netting agreements with the counterparties, as appropriate.
	The Company has entered into agreements with derivative counterparties, which include netting arrangements whereby the counterparties are entitled to settle their positions on a net basis. In certain circumstances, the Company is required to provide certain derivative counterparties collateral against derivative financial instruments. As of December 31, 2014 and 2013, counterparties held $4,482 and $730, respectively, of the Company’s cash and cash equivalents in margin accounts as collateral (which is classified as "Restricted cash" on the Company's consolidated balance sheets), after which the Company was in a net credit loss position of $4,562 and $2,790 at December 31, 2014 and 2013, respectively, to those counterparties. For the years ended December 31, 2014 and 2013, the Company incurred no credit losses due to non-performance of any of its counterparties.

Transfers and Servicing [Abstract]
Mortgage Servicing Rights	Mortgage Servicing Rights
	The Company sells residential mortgage loans in the secondary market and typically retains the right to service the loans sold. Upon sale, an MSRs asset is capitalized, which represents the current fair value of the future net cash flows that are expected to be realized for performing servicing activities. The Company also purchases MSRs directly from third parties.
	Effective January 1, 2013, the Company elected to irrevocably account for the subsequent measurement of its existing
	originated mortgage loans class of MSRs using the fair value method, whereby the MSRs are initially recorded on our balance sheet at fair value with subsequent changes in fair value recorded in earnings during the period in which the changes in fair value occur. We believe that accounting for the MSRs at fair value best reflects the impact of current market conditions on our MSRs, and our investors and other users of our financial statements will have greater insight into management’s views as to the value of our MSRs at each reporting date. The fair value of the MSRs is assessed at each reporting date using the methods described above. In accordance with the applicable GAAP guidance, this change in accounting principle was accounted for on a prospective basis (financial statement periods prior to 2013 have not been restated). We did not record a cumulative-effect adjustment to retained earnings as of January 1, 2013, as the net amortized carrying value of the MSRs as of January 1, 2013 equaled the fair value due to MSR impairment charges recorded during 2012.
	Prior to January 1, 2013, the subsequent measurement of the Company’s MSRs was recorded using the amortization
	method. Under the amortization method, capitalized MSRs were initially recorded at fair value and amortized over the
	estimated economic life of the related loans in proportion to the estimated future net servicing revenue. The net capitalized cost
	of MSRs was periodically evaluated to determine whether capitalized amounts were in excess of their estimated fair value. For
	this fair value assessment, the Company stratified its MSRs based on interest rates: (1) those with note rates below 4.00%; (2)
	those with note rates between 4.00% and 4.99%; and (3) those with note rates above 5.00%. If the amortized book value of the
	MSRs exceeded its fair value, management recorded a valuation adjustment as a reduction to the mortgage servicing right asset.
	However, in the event that the fair value of the MSRs recovered, the valuation allowance was reversed.
	The Company’s total mortgage servicing portfolio as of December 31, 2014 and December 31, 2013 is summarized as follows (based on the unpaid principal balance ("UPB") of the underlying mortgage loans):
		December 31, 2014			December 31, 2013

	1 GNMA portfolio balance is made up of Federal Housing Administration ("FHA"), Veterans Affairs ("VA"), and United States Department of Agriculture ("USDA") home loans.
	At December 31, 2014 and 2013, the Company held $380,576 and $155,562 of escrow funds for its customers for
	which it services mortgage loans.
	A summary of the changes in the balance of MSRs for the years ended December 31, 2014, 2013 and 2012 is as follows:
		Years Ended December 31,

	Balance at end of period	$	204,216		$	170,294		$	42,202
	During 2014, the Company completed two sales of loan pools, in the amount of $3,840 of UPB in FNMA MSRs to an unrelated third party. These pools of FNMA MSRs were somewhat geographically focused, had average mortgage interest rates that were less than current mortgage interest rates, and did not include any GNMA or FHLMC MSRs, which have a different valuation than FNMA MSRs. Thus, the characteristics of the pools did not represent the characteristics of the Company’s MSRs portfolio as a whole. The Company performed temporary sub-servicing activities with respect to the underlying loans through the established transfer date in the fourth quarter of 2014, for a fee, during which time the Company was also entitled to certain other ancillary income amounts. The Company used the proceeds to reinvest back into newly originated MSRs through its origination platform. There were various minor protection provisions for which an estimated $500 liability was accrued at the time of the first transaction. These MSRs sale transactions met the criteria for derecognition, allowing for the MSRs asset to be derecognized and gains to be recorded at the time of transfer. The total gains of $1,082 were net of direct transaction expenses and estimated protection provisions.
	Under certain of the Company's secured borrowing arrangements, the Company is required to pledge mortgage servicing rights as collateral to the secured borrowings. As of December 31, 2014, the Company had pledged $203,811 in fair value of mortgage servicing rights as collateral to secure debt under certain of its secured borrowing arrangements. As of December 31, 2013, no mortgage servicing rights were pledged as collateral to the Company's secured borrowing arrangements. Refer to Note 12 “Debt” for additional information related to the Company’s outstanding borrowings as of December 31, 2014 and December 31, 2013.
	The following is a summary of the components of loan servicing fees as reported in the Company’s consolidated statements of operations for the years ended December 31, 2014, 2013 and 2012:

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements
	The Company uses fair value measurements in fair value disclosures and to record certain assets and liabilities at fair value on a recurring basis, such as MSRs, derivatives and loans held for sale, or on a nonrecurring basis, such as when measuring intangible assets and long-lived assets. The Company has elected fair value accounting for loans held for sale to more closely align the Company’s accounting with its interest rate risk strategies without having to apply the operational complexities of hedge accounting.
	The Company groups its assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:
	Level Input:	Input Definition:
	Level 1	Unadjusted, quoted prices in active markets for identical assets or liabilities.
	Level 2	Prices determined using other significant observable inputs. Observable inputs are inputs that other market participants would use in pricing an asset or liability and are developed based on market data obtained from sources independent of the Company. These may include quoted prices for similar assets and liabilities, interest rates, prepayment speeds, credit risk and others.
	Level 3	Prices determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity), unobservable inputs may be used. Unobservable inputs reflect the Company's own assumptions about the factors that market participants would use in pricing the asset or liability, and are based on the best information available in the circumstances.
	An asset or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.
	While the Company believes its valuation methods are appropriate and consistent with those used by other market participants, the use of different methods or assumptions to estimate the fair value of certain financial statement items could result in a different estimate of fair value at the reporting date. Those estimated values may differ significantly from the values that would have been used had a readily available market for such items existed, or had such items been liquidated, and those differences could be material to the consolidated financial statements.
	Management incorporates lack of liquidity into its fair value estimates based on the type of asset or liability measured and the valuation method used. The Company uses discounted cash flow techniques to estimate fair value. These techniques incorporate forecasting of expected cash flows discounted at appropriate market discount rates that are intended to reflect the lack of liquidity in the market.
	The following describes the methods used in estimating the fair values of certain financial statement items:
	Mortgage Loans Held for Sale: The Company's mortgage loans held for sale at fair value are saleable into the secondary mortgage markets and their fair values are estimated using observable quoted market or contracted prices or market price equivalents, which would be used by other market participants.
	Derivative Financial Instruments: The Company estimates the fair value of interest rate lock commitments based on the value of the underlying mortgage loan, quoted MBS prices and estimates of the fair value of the MSRs and the probability that the mortgage loan will fund within the terms of the interest rate lock commitment. The Company estimates the fair value of forward sales commitments based on quoted MBS prices.
	Mortgage Servicing Rights: The Company uses a discounted cash flow approach to estimate the fair value of MSRs. This approach consists of projecting servicing cash flows discounted at a rate that management believes market participants would use in their determinations of value. The Company obtains valuations from an independent third party on a monthly basis, to support the reasonableness of the fair value estimate generated by the internal model. The key assumptions used in the estimation of the fair value of MSRs include prepayment speeds, discount rates, default rates, cost to service, contractual servicing fees and escrow earnings. In valuing the fair value of MSRs, the Company uses a forward yield curve as an input which will impact pre-pay estimates and the value of escrows as compared to a static forward yield curve. The Company believes that the use of the forward yield curve better represents fair value of MSRs because the forward yield curve is the market’s expectation of future interest rates based on its expectation of inflation and other economic conditions.

Contingent Earn-out Liability
Contingent earn-out liabilities resulted from the Company’s acquisitions of NattyMac in August 2012, Crossline in December 2013 and Medallion in February 2014. See Note 4, “Business Combinations,” within this Annual Report on Form 10-K for additional information related to these contingent earn-out liabilities.

2 Represents the Company’s acquisition of Medallion during February 2014.
The Company estimated the fair value of its earn-outs as of December 31, 2014 using the same method as at acquisition date for each of its earn-out liabilities, except for the Crossline earnout as discussed below. For the year ended December 31, 2014, the Company adjusted its earn-out liability for NattyMac by an increase of $14. For the year ended December 31, 2013, the Company revised its estimated fair value of the contingent earn-out liability related to the acquisition of NattyMac by increasing it $57 from its original acquisition-date fair value primarily due to the estimated timing of mortgage loan fundings from the NattyMac warehousing business. For the year ended December 31, 2014, as discussed in Note 4, “Business Combinations,” the Company decreased its estimate related to Medallion $153.
For the year ended December 31, 2014, the Company adjusted its earn-out liability for Crossline by an increase of $110. Transfers out of Level 3 relate to the Crossline earnout. Effective September 30, 2014, the Company amended the agreement governing the earnout provisions related to the acquisition of Crossline. As a result of the amendment, the remaining earnout amount to be paid to the original seller was fixed and is no longer contingent. Given the earnout amount is fixed, quoted and considered representative of the fair value of the liability, the Crossline earnout was transferred into Level 1. Transfers between levels, if any, are recorded as of the beginning of the reporting period. During the year ended December 31, 2013, there were no other transfers between levels.
Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances. As disclosed in Note 4, "Business Combinations," we completed our acquisition of Medallion on February 4, 2014. The values of the net assets acquired in the acquisition of Medallion and resulting goodwill were recorded at fair value using Level 3 inputs. Refer to Note 4, "Business Combinations," for further information regarding the methodology and key assumptions used in the acquisition date fair value estimates.
Fair Value of Other Financial Instruments
As of December 31, 2014 and December 31, 2013, all financial instruments were either recorded at fair value or the carrying value approximated fair value. For financial instruments that were not recorded at fair value, such as cash, restricted cash, servicing advances, secured borrowings, warehouse and operating lines of credit, accounts payable and accrued expenses, their carrying values approximated fair value due to the short-term nature of such instruments.

Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets
	A summary of the change in the carrying amount of goodwill for the years ended December 31, 2014 and December 31, 2013 is as follows:
			Goodwill
	Balance at December 31, 2012		$	—
	Crossline business combination		3,638
	Balance at December 31, 2013		$	3,638
	Medallion business combination		627
	Balance at December 31, 2014		$	4,265
	The Company performed its annual assessment of possible impairment of goodwill associated with both Crossline and Medallion as of November 30. This assessment will be performed more frequently if events and circumstances indicate that impairment may have occurred. The Company's goodwill is attributable to the Originations segment of the business and its analysis was performed at this segment level, with no impairment noted during the year ended December 31, 2014.
	The Company's other intangible assets relate to its asset acquisition of NattyMac, LLC. in 2012 and acquisition of Crossline Capital, Inc. in 2013, as described in Note 4, "Business Combinations." The components of the Company's other intangible assets as of December 31, 2014 and December 31, 2013 are as follows:

	Given the formation of Stonegate Direct in October 2014, which was integrated through the call center operations of Crossline, the Company determined there was a significant change in the manner in which the Crossline trade name was used and as a result determined the change to be a triggering event for an impairment analysis to be performed in accordance with the guidance of long-lived assets. The amount of impairment represents the remaining net carrying amount of the asset and is recognized in the consolidated statements of operations within "Loss on disposal and impairment of long lived assets." The Crossline trade name and associated impairment charge relate to our Originations segment.
	The Company recorded amortization expense related to its definite-lived intangible assets of $1,019, $360 and $120 during the years ended December 31, 2014, 2013 and 2012, respectively. Estimated future amortization expense for each of the years ended December 31, is as follows: 2015, $486; 2016, $486; 2017, $338; 2018, $294; 2019, $294; thereafter, $196. Estimated amortization expense was based on existing intangible asset balances as of December 31, 2014. Actual amortization expense may vary from these estimates.
	The Company performed its annual impairment test of existing other intangible assets with indefinite lives (trade name) as of October 1, 2014, with no impairment noted as of October 1, 2014.

Transfers and Servicing [Abstract]
Transfers and Servicing of Financial Assets	Transfers and Servicing of Financial Assets
	Residential mortgage loans are primarily sold to FNMA or FHLMC or transferred into pools of GNMA MBS. The Company has continuing involvement in mortgage loans sold through servicing arrangements and the liability for loan indemnifications and repurchases under the representation and warranties it makes to the investors and insurers of the loans it sells. The Company is exposed to interest rate risk through its continuing involvement with mortgage loans sold, including the MSRs, as the value of the asset fluctuates as changes in interest rates impact borrower prepayment.
	The Company also sells non-agency residential mortgage loans to non-GSE third parties without retaining the servicing rights to such loans.
	All loans are sold on a non-recourse basis; however, certain representations and warranties have been made that are customary for loan sale transactions, including eligibility characteristics of the mortgage loans and underwriting responsibilities, in connection with the sales of these assets.
	In order to facilitate the origination and sale of mortgage loans held for sale, the Company entered into various agreements with warehouse lenders. Such agreements are in the form of loan participations and repurchase agreements with banks and other financial institutions. Mortgage loans held for sale are considered sold when the Company surrenders control over the financial assets and such financial assets are legally isolated from the Company in the event of bankruptcy. For loan participations and repurchase agreements that meet the sale criteria, the transferred financial assets are derecognized from the balance sheet and a gain or loss is recognized upon sale. If the sale criteria are not met, the transfer is recorded as a secured borrowing in which the assets remain on the balance sheet and the proceeds from the transaction are recognized as a liability. As of December 31, 2014 and 2013, all repurchase agreements are accounted for by the Company as secured borrowings.
	From time to time, the Company may sell loans whereby the underlying risks and cash flows of the mortgage loan have been transferred to a third party through the issuance of participating interests. The terms and conditions of these interests are governed by the participation agreements. The Company will receive a marketing fee paid by the participating entity upon completion of the sale. In addition, the Company will also subservice the underlying mortgage loans to the participation agreement for the period that the participating interests are outstanding. As of December 31, 2014 and 2013, all participation arrangements were accounted for by the Company as secured borrowings.
	The following table sets forth information regarding cash flows for the years ended December 31, 2014, 2013 and 2012 relating to loan sales in which the Company has continuing involvement:
		Years Ended December 31,

	1 Represents the proceeds from mortgage loans or pools of mortgage loans sold, net of the related repayments of borrowings under the Company's mortgage funding arrangements used to fund the related mortgage loans prior to sale as well as the cost to retain the servicing rights.
	The following table sets forth information related to outstanding loans sold as of December 31, 2014 and December 31, 2013 for which the Company has continuing involvement:
		December 31, 2014			December 31, 2013

	1 Includes GNMA mortgage loans eligible for repurchase and recorded on the consolidated balance sheet, which are government-insured, of $109,397 and $26,268, respectively, as of December 31, 2014 and December 31, 2013.
	The key weighted average assumptions (or range of assumptions) used in determining the fair value of the Company’s MSRs as of December 31, 2014 and December 31, 2013 are as follows:
		December 31, 2014		December 31, 2013
	Discount rates	9.25% - 11.00%		9.25% - 11.00%
	Annual prepayment speeds (by investor type):
	FNMA	13.90%		7.80%
	GNMA:
	FHA	11.20%		7.70%
	VA	10.10%		7.50%
	USDA	11.80%		7.50%
	FHLMC	13.10%		7.70%
	Other Investors	12.40%		N/A
	Cost of servicing (per loan)	$83		$74
	The key assumptions (or range of assumptions) used in determining the fair value of the Company’s MSRs at initial recognition during the years ended December 31, 2014, 2013 and 2012 are as follows:
		Years Ended December 31,
		2014		2013	2012
	Discount rates	9.25% - 11.00%		9.25% - 11.00%	8.00% - 11.00%
	Annual prepayment speeds (by investor type):
	FNMA	7.90% - 13.92%		7.79% - 10.38%	6.00% - 14.26%

	Cost of servicing (per loan)	$74 - $83		$73 - $74	$70 - $90
	MSRs are generally subject to loss in value when mortgage rates decrease. Decreasing mortgage rates normally encourage increased mortgage refinancing activity. Increased refinancing activity reduces the life of the loans underlying the MSRs, thereby reducing MSRs value. Reductions in the value of MSRs affect income through changes in fair value. These factors have been considered in the estimated prepayment speed assumptions used to determine the fair value of the Company’s MSRs.
	In addition to the assumptions provided above, the Company uses assumptions for default rates in determining the fair value of MSRs. These assumptions are based primarily on internal estimates, and the Company also obtains third party data, where applicable, to assess the reasonableness of its internal assumptions.  The Company's assumptions for default rates for FNMA, GNMA, FHLMC and Other Investors mortgage loans as of December 31, 2014 and December 31, 2013 are as follows:
		December 31, 2014		December 31, 2013
	FNMA	3.93%		3.97%
	GNMA:
	FHA	6.42%		6.45%
	VA	6.31%		6.37%
	USDA	6.29%		6.41%
	FHLMC	3.80%		3.82%
	Other Investors	6.14%		N/A
	The default rates represent the Company’s estimate of the loans that will eventually enter foreclosure proceedings over the entire term of the portfolio’s life.  These assumptions affect the future cost to service loans, future revenue earned from the portfolio, and future assumed foreclosure losses.  Because the Company’s portfolio is generally comprised of recent vintages, actual future defaults may differ from the Company’s assumptions.
	The hypothetical effect of an adverse change in these key assumptions would result in a decrease in the fair values of MSRs as follows as of December 31, 2014 and December 31, 2013:
		December 31, 2014			% of Average Portfolio			December 31, 2013			% of Average Portfolio
	Discount rates:
	Impact of discount rate + 1%	$	(8,345	)	4	%		$	(8,706	)	5	%
	Impact of discount rate + 2%	$	(16,063	)	8	%		$	(16,638	)	10	%
	Impact of discount rate + 3%	$	(23,222	)	11	%		$	(23,889	)	14	%
	Prepayment speeds:
	Impact of prepayment speed * 105%	$	(5,445	)	3	%		$	(3,558	)	2	%
Impact of prepayment speed * 110%	$	(10,668	)	5	%		$	(7,003	)	4	%
Impact of prepayment speed * 120%	$	(20,508	)	10	%		$	(13,570	)	8	%
Cost of servicing:
Impact of cost of servicing * 105%	$	(1,529	)	1	%		$	(1,157	)	1	%
Impact of cost of servicing * 110%	$	(3,058	)	1	%		$	(2,314	)	1	%
Impact of cost of servicing * 120%	$	(6,116	)	3	%		$	(4,629	)	3	%
As the table demonstrates, the Company’s methodology for estimating the fair value of MSRs is highly sensitive to changes in assumptions. For example, actual prepayment experience may differ and any difference may have a material effect on MSRs fair value. Changes in fair value resulting from changes in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, in this table, the effect of a variation in a particular assumption on the fair value of the MSRs is calculated without changing any other assumption; in reality, changes in one factor may be associated with changes in another (for example, decreases in market interest rates may indicate higher prepayments; however, this may be partially offset by lower prepayments due to other factors such as a borrower’s diminished opportunity to refinance), which may magnify or counteract the sensitivities. Thus, any measurement of MSRs fair value is limited by the conditions existing and assumptions made as of a particular point in time. Those assumptions may not be appropriate if they are applied to a different point in time.

	The Company maintains mortgage loan participation, repurchase and warehouse lines of credit arrangements (collectively referred to as “mortgage funding arrangements”) with various financial institutions, primarily to fund the origination of mortgage loans. As of December 31, 2014, the Company held mortgage funding arrangements with three separate financial institutions and a total maximum borrowing capacity of $1,634,000. Each mortgage funding arrangement is collateralized by the underlying mortgage loans. Separately, the Company had two mortgage funding arrangements for the funding of MSRs, each of which is collateralized by the particular MSRs being funded.
	The following table summarizes the amounts outstanding, interest rates and maturity dates under the Company’s various mortgage funding arrangements as of December 31, 2014:
	Mortgage Funding Arrangements1		Amount Outstanding			Maximum Borrowing Capacity				Interest Rate	Maturity Date

	1 Does not include our operating lines of credit for which we have a maximum borrowing capacity of $2,000.
	2 Merchants Bank of Indiana will periodically constrain the aggregate maximum borrowing capacity. During the year ended December 31, 2014, the most the aggregate maximum borrowing capacity was constrained approximated $500,000. At December 31, 2014, the aggregate maximum borrowing capacity was $600,000.
	3 The maximum borrowing capacity is a sublimit of the Merchants Participation Agreement maximum borrowing capacity of $600,000 referred to in Note 2 above.
	4 Governed by the Barclays Bank PLC maximum borrowing capacity of $400,000, with a sub-limit of $100,000.
	5 Based on GNMA MSRs pledged to Merchants Bank of Indiana. Subsequent to year end, such capacity was raised to $35,000.
	6 The Bank of America maximum borrowing includes $400,000 of mortgage repurchase and $200,000 of mortgage gestation repurchase facilities.
	7 Agreement automatically renews 90 days prior to maturity if no termination notice given by either party. No notice was received or given at the 90 day mark and this line was extended to a maturity date of March 2016.
	On August 29, 2014, the Company entered into a secured borrowing with a syndicate of banks led by Merchants Bank, secured by the Company’s GNMA mortgage servicing rights. The maximum borrowing capacity at the time of initiation was $22,000, which could be expanded upon with the addition of additional banks to the syndicate. The borrowing matures on June 30, 2017 and carries an interest rate of one-month LIBOR plus 450 basis points. The amount of the borrowing is measured on a quarterly basis to ensure that it is less than 50% of the value of the GNMA mortgage servicing rights collateralizing the secured borrowing. For the purpose of this test, the value of the GNMA mortgage servicing rights is equal to the value of the related MSRs established by the Company on a quarterly basis. On October 23, 2014, the Company amended the financing agreement to increase the amount of the borrowing from $22,000 to $27,000, and on December 30, 2014, the Company amended the financing agreement to further increase the amount of the borrowing to $30,000. On February 9, 2015, the Company amended the agreement to increase the maximum borrowing capacity to $35,000.
	On May 22, 2014, the Company entered into a loan and security agreement with Barclays Bank PLC ("Barclays") in which the Company established a $100,000 revolving credit facility secured by the Company's FNMA and FHLMC MSRs. The transaction was structured so that the $100,000 revolving credit facility with Barclays is a borrowing sub-limit within the Company's existing $300,000 master repurchase agreements with Barclays. As part of the transaction, the Company, together with Barclays, entered into separate acknowledgment agreements with FNMA and FHLMC in which, among other things, FNMA and FHLMC acknowledge the lien against the Company’s FNMA and FHLMC MSRs. On July 7, 2014, the Company amended its master repurchase agreement with Barclays to increase the aggregate maximum borrowing capacity from $300,000 to $400,000, which was accounted for as a modification of a revolving debt arrangement. The master repurchase agreement, together with the loan and security agreement, was to mature on December 16, 2014. On December 16, 2014, the Company amended and renewed its master repurchase and mortgage loan participation purchase and sale, and the MSRs loan and security agreement. The agreements will mature on December 16, 2015. The maximum borrowing capacity and associated interest rate remain the same.
	On April 15, 2014, the Company entered into an agreement with Merchants Bancorp (an Indiana-based bank holding company and the parent company of Merchants Bank of Indiana), whereby the Company agreed to invest up to $25,000 in the subordinate debt of Merchants Bancorp. Merchants Bancorp in turn, agreed to form and fund a wholly-owned subsidiary named NattyMac Funding Inc. (“NMF”) that would invest in participation interests in warehouse lines of credit ("WLOCs") originated by the Company's wholly-owned subsidiary, NattyMac, and in participation interests in residential mortgage loans originated by Stonegate. Additionally, Merchants Bancorp of Indiana ("Merchants") pledged 1,000 shares of NMF's common capital stock to the Company, for which the Company has the right to claim if Merchants were to default on any parameters set forth by the agreement. The amount of the subordinate debt funded by the Company is designed to be greater than or equal to 10% of the assets of NMF, based on the average assets of NMF over the quarter period. The subordinate debt provided to Merchants Bancorp will earn a return equal to one-month LIBOR, plus 350 basis points, plus additional interest that will be equal to 49% of the earnings of NMF. On September 25, 2014, the Company expanded the maximum amount of its investment in the subordinate debt of Merchants Bancorp to $30,000. At December 31, 2014, the Company had invested $30,000 in the subordinate debt of Merchants Bancorp and is presented in the "Subordinated loan receivable" on the Company's consolidated balance sheets herein. In addition, the amount of residential and warehouse participations outstanding as of December 31, 2014 totaled $319,457 which was recorded for as secured borrowings and included in “Secured borrowings - mortgage loans” on the Company’s consolidated balance sheet herein.
	On March 31, 2014, the Company amended its master participation agreement with Merchants to increase the aggregate maximum borrowing capacity from $400,000 to $600,000 through May 31, 2014. Through a series of further amendments, the Company's current master participation agreement with Merchants has an aggregate maximum borrowing capacity of $600,000 and a maturity date of July 31, 2015.
	In addition to the master participation agreement with Merchants, the Company also has an operating line of credit and a warehouse line of credit with Merchants. The operating line of credit is unsecured and the warehouse line of credit is secured by residential mortgages owned by the Company. The available borrowing amounts under both the operating line of credit and the warehouse line of credit went through a series of increases and reductions via amendments from March 31, 2014 to September 9, 2014, such that as of December 31, 2014, the operating line of credit was a $2,000 borrowing facility and the warehouse line of credit was also a $2,000 borrowing facility.
	On March 25, 2014, the Company amended its master repurchase agreement with Bank of America, N.A. ("Bank of America") to increase the aggregate outstanding purchase price under the agreement from $200,000 to $250,000 and extend the termination date to April 30, 2014. On April 30, 2014, the master repurchase agreement with Bank of America was amended further to extend the maturity date to May 31, 2014. On May 12, 2014, the master repurchase agreement with Bank of America was increased to $300,000 and renewed until its maturity date of May 11, 2015 and the master participation agreement of $100,000 was renewed until its maturity date of May 11, 2015. On September 26, 2014, the master participation agreement of $100,000 was expanded to $200,000. On November 4, 2014, the Company amended its mortgage repurchase financing with Bank of America to expand the amount available under the line from $300,000 to $400,000. In the amendment, the Company also revised the profitability covenant for the Bank of America financing, to be hereafter calculated as pre-tax income for the trailing six months, excluding the change in mortgage servicing rights valuation.
	The above mortgage funding and operating lines of credit agreements contain covenants which include certain financial requirements, including maintenance of minimum tangible net worth, maximum debt to tangible net worth ratio, minimum liquidity, minimum current ratio, minimum profitability and limitations on additional debt and transactions with affiliates, as defined in the respective agreement. As of December 31, 2014, the Company was in compliance with the covenants contained in its borrowings. The Company intends to renew the mortgage funding arrangements when they mature and has no reason to believe the Company will be unable to do so.

Reserve for Mortgage Repurchases and Indemnifications	Reserve for Mortgage Repurchases and Indemnifications
	Representations and warranties are provided to investors and insurers on loans sold and are also assumed on purchased mortgage loans. In the event of a breach of these representations and warranties, the Company may be required to repurchase the mortgage loan or indemnify the investor against loss. In limited circumstances, the full risk of loss on loans sold is retained to the extent the liquidation of the underlying collateral is insufficient. In some instances where the Company has purchased loans from third parties, it may have the ability to recover the loss from the third party originator. Repurchase and foreclosure-related reserves are maintained for probable losses related to repurchase and indemnification obligations and for on-balance sheet loans in foreclosure and real estate owned.
	The following is a summary of changes in the reserve for mortgage repurchases and indemnifications for the years ended December 31, 2014, 2013 and 2012:
		Years Ended December 31,

	1 Recognized as a reduction to "Gain on mortgage loans held for sale, net" in the consolidated statements of operations.
	2 Accounts for change in estimate made subsequent to the initial reserve for new loan sales being made.
	Because of the inherent uncertainties involved in the various estimates and assumptions used by the Company in determining the mortgage repurchase and indemnifications liability, there is a reasonable possibility that future losses may be in excess of the recorded liability. In assessing the adequacy of the reserve, management evaluates various factors including actual losses on repurchases and indemnifications during the period, historical loss experience, known delinquent and other problem loans, delinquency trends in the portfolio of sold loans and economic trends and conditions in the industry. The Company considers the liability to be appropriate at each balance sheet date.

The agreement was terminated on May 15, 2013 in conjunction with the Company’s private offering of common stock. The total management fees amounted to $820 and $238, respectively, for the years ended December 31, 2013 and 2012, and are included in "General and administrative expense" on the Company's consolidated statements of operations.
	Through June 30, 2013, the Company had an agreement with a stockholder to manage and grow the Company’s Home Improvement Program division, which primarily focuses on the origination of the Federal Housing Administration ("FHA") 203k loans and Fannie Mae Home Style renovation loans. In accordance with the terms of the agreement the stockholder was to receive an annual management fee of $108 payable quarterly through January 15, 2014, 10% of all revenue generated by the division payable quarterly through January 15, 2014, and 33.33% of the annual net income of the division for the calendar year ended December 31, 2013. This agreement terminated on June 30, 2013. The total related fees amounted to $159 and $339, respectively for the years ended December 31, 2013 and 2012, and are included in "General and administrative expense" on the Company's consolidated statements of operations.
	During the year ended December 31, 2013, the Company forgave a note receivable from its Chief Executive Officer ("CEO") in the amount of $214, which was considered taxable income to the CEO and compensation expense to the Company.
	As of December 31, 2013, the Company had $608 of amounts due to related parties, which primarily consisted of the previously described management fees as well as fees payable to members of the Company's Board of Directors.

	As of December 31, 2014, the Company had federal and state net operating loss carryforwards of $148,580 and $125,957, respectively, available to offset future taxable income and expiring from 2027 to 2034. As of December 31, 2013, the Company had federal and state net operating loss carryforwards of $94,973 and $64,241, respectively. The increase in both the federal and state net operating loss carryforwards during the year ended December 31, 2014 was due primarily to increases in timing differences related to originated MSRs and derivative assets and liabilities (IRLCs and related forward MBS trades). Because the Company’s primary business activity consists of the origination and sale of mortgage loans with the retention of servicing rights, these sales typically result in the recognition of gains for book purposes. However, because the servicing retained by the Company constitutes normal servicing, as that term is defined in applicable income tax guidance of the Internal Revenue Code, these sales do not result in the recognition of a corresponding amount of taxable gain. Similarly, the Company’s IRLCs and related forward MBS trades are recorded as derivative financial instruments and changes in fair value are recorded for book purposes under GAAP. However, the IRLCs and forward MBS trades with respect to the IRLCs are not subject to mark-to-market adjustments for tax purposes.
	The Company analyzed the impact of its October 10, 2013 initial public offering (as further described in Note 17, "Capital Stock") and determined that an ownership change under Section 382 of the Internal Revenue Code ("Section 382 ownership change") occurred. The Internal Revenue Service ("IRS") allows for the application of two approaches (the full value method and the hold constant principle) for valuing companies when identifying a Section 382 ownership change and requires that the taxpayers apply a consistent method from year to year.      As a result of the ownership change, the Company evaluated the impact to the net operating loss carryforward. Management calculated the resulting annual limitation on the utilization of the Company's net operating loss carryforwards and determined that it was more likely than not that the net operating loss carryforwards will be utilized prior to their expiration. Accordingly, no valuation allowance has been established at December 31, 2014 and 2013.
	The Company also analyzed the impact of its private equity offering that occurred on May 15, 2013 (as further described in Note 17, “Capital Stock”) and determined whether a Section 382 ownership change had occurred. The Company applied the full value method in its valuation and analysis of the Section 382 ownership change and, as a result, determined that a Section 382 ownership change did not occur.
	As a result of a significant investment made by holders of Series D convertible preferred stock (as further described in Note 17, “Capital Stock”) on March 9, 2012, the Company experienced a Section 382 ownership change. Management performed an analysis of the resulting annual limitation on the utilization of the Company's net operating loss carryforwards and, based on that analysis, determined that it was more likely than not that these net operating loss carryforwards will be utilized prior to their expiration.  Accordingly, no valuation allowance has been established at December 31, 2014 and 2013.

Commitments_and_Contingencies

Commitments and Contingencies	12 Months Ended
	Dec. 31, 2014
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies
	Commitments to Extend Credit
	The Company enters into IRLCs with customers who have applied for residential mortgage loans and meet certain credit and underwriting criteria. These commitments expose the Company to market risk if interest rates change and the loan is not economically hedged or committed to an investor. The Company is also exposed to credit loss if the loan is originated and not sold to an investor and the customer does not perform. The collateral upon extension of credit typically consists of a first deed of trust in the mortgagor’s residential property. Commitments to originate loans do not necessarily reflect future cash requirements as some commitments are expected to expire without being drawn upon. Total commitments to originate loans as of December 31, 2014 and December 31, 2013 approximated $1,211,675 and $1,190,119, respectively. The commitments are recognized in the balance sheet within “Derivatives".
	Leases
	The Company leases office space and equipment under non-cancelable operating agreements expiring through October 2022. Rent expense amounted to $9,237, $3,458 and $1,259 for the years ended December 31, 2014, 2013 and 2012, respectively. Future minimum rental payments under the leases having an initial or remaining non-cancelable term in excess of one year are as follows at December 31, 2014:
	2015	$	7,536
	2016	6,632
	2017	6,325
	2018	5,511
	2019	3,827
	Thereafter	4,968
	Total minimum rental payments	$	34,799
	Regulatory Net Worth Requirements
	The Company is subject to various regulatory capital requirements administered by the Department of Housing and Urban Development ("HUD"), which governs non-supervised, direct endorsement mortgagees, and GNMA, FNMA and FHLMC, which governs issuers of GNMA, FNMA and FHLMC securities. Additionally, the Company is required to maintain minimum net worth requirements for many of the states in which it sells and services loans. Each state has its own minimum net worth requirement; these range from $0 to $1,000, depending on the state.
	Failure to meet minimum capital requirements can result in certain mandatory and possibly additional discretionary remedial actions by regulators that, if undertaken, could (i) remove the Company’s ability to sell and service loans to or on behalf of the agencies and (ii) have a direct material effect on the Company’s financial statements. In accordance with the regulatory capital guidelines, the Company must meet specific quantitative measures of assets, liabilities and certain off-balance sheet items calculated under regulatory accounting practices. Further, changes in regulatory and accounting standards, as well as the impact of future events on the Company’s results, may significantly affect the Company’s net worth adequacy.
	The Company met all minimum net worth requirements to which it was subject as of December 31, 2014 and 2013. The Company’s required and actual net worth amounts are presented in the following table:
		December 31, 2014				December 31, 2013
		Net Worth 1		Net Worth Required		Net Worth 1		Net Worth Required
	HUD	$	272,686	$	2,500	$	298,429	$	2,500
	GNMA	$	272,686	$	22,982	$	298,429	$	12,667
	FNMA	$	272,686	$	16,995	$	298,429	$	20,635
	FHLMC	$	272,686	$	11,251	$	298,429	$	2,905
	Various States	$	272,686	$ 0-1,000		$	298,429	$ 0-1,000
	1 Calculated in compliance with the respective agencies' or states' requirements.
	Litigation
	The Company is subject to various legal proceedings arising out of the ordinary course of business. As of December 31, 2014, there were no current or pending claims against the Company, which could have a material impact on the Company's statement of financial position, net income or cash flows.
	Regulatory Contingencies
	The Company is subject to periodic audits and examinations, both formal and informal in nature, from various federal and state agencies, including those made as part of regulatory oversight of our mortgage origination, servicing and financing activities. Such audits and examinations could result in additional actions, penalties or fines by state or federal governmental bodies, regulators or the courts with respect to our mortgage origination, servicing and financing activities, which may be applicable generally to the mortgage industry or to us in particular.  During 2014, we received a report of examination from a state regulatory agency that certain fees that were charged to borrowers in connection with the origination of loans through our wholesale and retail channels were impermissible and must be refunded to such borrowers.  The total amount of these fees is $417. The Company disagrees with the findings in the report of examination and has communicated its reasoning as to why the related fees are permissible to the state regulatory agency.  However, there can be no assurance that the state regulatory agency will agree with our position and that we will not be ultimately required to refund the fees to the related borrowers.
	Other Contingencies
	During 2013, the Company became aware that it had purchased certain refinancing loans, with a total principal amount of $5,163, from a correspondent lender where the prior mortgage loan on the property securing the mortgage loan that was purchased from the correspondent lender was not satisfied and released by the correspondent’s title company at the time the loan from the correspondent was made. As part of the Company’s process in purchasing a mortgage loan from a correspondent lender, it generally requires that a closing protection letter be issued by the title insurer in favor of the borrower. A closing protection letter was obtained with respect to each of these purchased loans. As a result, the Company believes the borrower is insured against any liens prior to ours that were not identified in connection with the issuance of that closing protection letter. The Company believes that its procedures, including conducting a post-purchase audit, were effective in identifying the failure by the correspondent lender to obtain a release of the prior mortgage loan and that the Company’s practice of obtaining closing protection letters is appropriate to protect it in these situations. The Company has notified the affected borrowers and the relevant insurance carriers, and it expects that the title insurance obtained in connection with the refinancings will result in the loan having a first priority status. However, there can be no assurances that the prior mortgages will be fully satisfied from the title insurance claims.

Equity [Abstract]
Capital Stock	Capital Stock
	Initial Public Offering
	On October 16, 2013, the Company completed its initial public offering of 8,165,000 shares of common stock (including 1,065,000 shares exercised pursuant to an overallotment option granted to the underwriters) at a price to the public of $16.00 per share, resulting in gross proceeds of approximately $130,640. The underwriting discounts and commissions related to this offering totaled $6,712 and the Company incurred additional equity issuance costs totaling $3,259 related to the initial public offering.
	Equity Restructuring
	On May 14, 2013, all outstanding shares of the Company’s convertible preferred stock (Series B, C and D) were converted into shares of the Company’s common stock on a one-for-one basis. On May 14, 2013, immediately following the conversion of preferred stock to common stock, each share of common stock held was split into 13.861519 shares of common stock.
	On May 15, 2013, the Company sold 6,388,889 shares of its common stock at a per share price of $18.00, for total gross proceeds of $115,000, under a private offering under the exemptions of the Securities Act of 1933, as amended (the “Securities Act”). The initial purchaser’s discount and placement fee related to the May 2013 offering totaled $7,700 and the Company incurred additional equity issuance costs totaling $2,700 related to the May 2013 offering.
	Issuance of Warrants
	On March 29, 2013, in conjunction with a $10,000 term loan the Company entered into with a stockholder, the Company issued warrants to the stockholder for the right to purchase 277,777 shares of its common stock at a price of $18.00 per share. The warrants are exercisable at any time through May 15, 2018. Because the warrants met the criteria of a derivative financial instrument that is indexed to the Company's own stock, the warrants' allocable fair value of $1,522 was recorded as a component of "Additional paid in capital" and resulted in a debt discount in the same amount. The debt discount was fully amortized into interest expense upon the repayment of the term loan in full, resulting in $1,522 of interest expense during the year ended December 31, 2013.
	Use of Capital and Common Stock Repurchases
	The Company paid total cash dividends of $27 and $119 to its convertible preferred stockholders during the years ended December 31, 2013 and December 31, 2012, respectively. The Company had no preferred stockholders during the year ended December 31, 2014. The Company does not expect to pay dividends on its common stock for the foreseeable future. The declaration of future dividends and the establishment of the per share amount, record dates and payment dates for any such future dividends are subject to the final determination of the Company’s Board of Directors and will be dependent upon future earnings, cash flows, financial requirements and other factors.
	Common stock repurchases are discretionary as the Company is under no obligation to repurchases shares. The Company may repurchase shares when it believes it is a prudent use of capital. There were no repurchases of common stock during the years ended December 31, 2014 or 2013.

Stock-Based Compensation	Stock-Based Compensation
	During 2011, the Company adopted the 2011 Omnibus Incentive Plan (the “2011 Plan”) for employees, consultants and non-employee directors. The Plan provided for the grant of stock options (both incentive stock options and nonqualified stock options), stock appreciation rights ("SARs"), restricted stock, performance units, phantom stock, restricted stock units and stock awards.
	On August 29, 2013, the Company adopted the 2013 Omnibus Incentive Plan (the "2013 Plan") for employees and consultants. The 2013 Plan provides for the grant of stock options (both incentive stock options and non-qualified stock options), SARs, restricted stock, restricted stock units, dividend equivalent rights, other stock-based or cash-based awards (collectively, “awards”), with each grant evidenced by an award agreement providing the terms of the award. Incentive stock options may be granted only to employees; all other awards may be granted to employees and consultants. Non-employee directors are not permitted to participate in the 2013 Plan. The 2013 Plan is applicable to all awards granted on or after August 29, 2013 and replaces the 2011 Plan. No new stock-based compensation grants were made under the 2011 Plan after the adoption of the 2013 Plan. The terms and conditions of awards granted under the 2011 Plan prior to the adoption of the 2013 will not be affected by the adoption of the 2013 Plan, and the 2011 Plan will remain effective with respect to such awards. Upon adoption on August 29, 2013, a total of 419,250 shares of the Company's common stock were reserved and available for issuance under the 2013 Plan, which included the 315,925 remaining number of shares available for grant under the 2011 Plan. As of December 31, 2014, there were a total of 327,856 shares of common stock available for future grants under the 2013 Plan.
	The Company’s current policy for issuing shares of its common stock upon exercise of stock options or vesting of restricted stock units is to either issue new shares or repurchase outstanding shares of its common stock to settle stock option exercises. The Company currently has no plans to repurchase shares of its common stock.
	Stock Options
	Nonqualified stock options are granted for a fixed number of shares with an exercise price at least equal to the fair value of the shares at the grant date. Nonqualified stock options granted during 2014 and 2013 generally vest over four years in equal annual installments and have a term of ten years from the grant date. Nonqualified stock options granted during 2012 vest over three years in equal quarterly installments and have a term of ten years from the grant date. Stock options granted do not contain any voting or dividend rights prior to exercise. The Company recognizes compensation expense associated with the stock option grants using the straight-line method over the requisite service period.
	A summary of stock option activity for the year ended December 31, 2014 is as follows:
		Number of Shares			Weighted Average				Weighted Average		Aggregate Intrinsic Value
					Exercise Price Per Share				Remaining Contractual Life (Years)
	Outstanding at December 31, 2013	1,539,880			$	17.08
	Granted	31,312			$	14.04
	Exercised	—			N/A
	Forfeited or expired	(165,986	)		$	18
	Outstanding at December 31, 2014	1,405,206			$	16.9			8.3		$	811
	Exercisable at December 31, 2014	412,772			$	15.13			8.1		$	676
	During the year ended December 31, 2014, 33,831 stock options with a per-share exercise price of $3.97, an aggregate intrinsic value of $270 and remaining contractual term of 7.2 years, vested.
	The Company uses the Black-Scholes option pricing model to estimate the fair value of stock options granted. The following assumptions were used to estimate the fair value of options granted during the years ended December 31, 2014, 2013 and 2012:
		Years Ended December 31,
		2014				2013				2012
	Fair value of underlying common stock	$	14.04			$	18			$	3.97
	Volatility	41.3		%		40		%		18		%
	Dividend yield	—		%		—		%		—		%
	Risk-free interest rate	2.01		%		1.08		%		1.01		%
	Expected term (years)	6.25				6.22				5.75
	The weighted average grant-date fair values per share of the stock options granted during the years ended December 31, 2014, 2013 and 2012 were $6.07, $7.25 and $0.78, respectively.
	Volatility was estimated based on the historical volatility of comparable publicly traded companies. The dividend yield was based on an estimate of future dividend yields. The risk-free interest rate was based on the U.S. Treasury zero-coupon yield curve in effect at the time of the grants. The expected term was calculated for each grant using the simplified method, as the Company’s outstanding stock option grant met certain SEC criteria for the use of the simplified method.
	During the year ended December 31, 2013, as a result of the May 14, 2013 stock-split, the Company modified a stock option award made to one non-employee director. The terms of the award were modified to increase the number of stock options from 7,322 shares to 101,494 shares and to decrease the exercise price of the stock options from $55.00 per share to $3.97 per share. The total incremental compensation costs resulting from this modification was $1,449, of which $682 was recorded as stock-based compensation expense for the year ended December 31, 2013.
	Restricted Stock Units
	Restricted stock units are granted for a fixed number of shares with a fair value equal to the fair value of the Company's common stock at the grant date. Restricted stock units granted during 2014 and 2013 vest over three years in equal annual installments. Restricted stock units granted do not contain any voting or dividend rights prior to vesting. The Company recognizes compensation expense associated with the restricted stock units using the straight-line method over the requisite service period.
	A summary of the nonvested restricted stock unit activity for the year ended December 31, 2014 is as follows:
		Restricted Stock Units			Weighted Average Grant Date Fair Value Per Share
	Nonvested at December 31, 2013	49,634			$	17.04
	Granted	10,448			$	13.65
	Vested	(11,737	)		$	(17.04	)
	Forfeited	(14,423	)		$	(17.04	)
	Nonvested at December 31, 2014	33,922			$	16
	The total fair value of restricted stock units converted into common stock was $200 during the year ended December 31, 2014.
	During the years ended December 31, 2014, 2013 and 2012, the Company recognized total stock-based compensation expense related to stock options and restricted stock units of $3,253, $2,452 and $13, respectively. During the years ended December 31, 2014, 2013 and 2012, the Company recognized related tax benefits of $2,087, $987 and $5, respectively. Total unrecognized stock-based compensation costs related to nonvested stock options and restricted stock units as of December 31, 2014 was $5,593 and $520, respectively, and will be recognized using the straight-line method over the weighted average remaining requisite service periods of 2.1 and 2.2 years, respectively.
	Other Stock Awards
	On May 10, 2013, the Company issued 39,145 shares of common stock (from its available treasury shares) to an employee who elected to receive his 2012 incentive compensation in the form of shares of the Company's common stock, as allowed under his employment agreement. The election under the employment agreement that allowed the employee to receive incentive compensation in either cash or the Company's common stock was accounted for as a tandem award compensation agreement. The fair value of the tandem award was determined to be $602 on the date the employee made the election to receive his incentive compensation in stock. Stock-based compensation expense recognized for this tandem award was $127 and $475, respectively, for the years ended December 31, 2013 and 2012. The number of shares of common stock issued to this employee upon settlement reflected a net settlement for payroll tax withholding. No such election was made during the year ended December 31, 2014.
	The Company has not granted any stock appreciation rights, restricted stock awards, performance units, phantom stock or other stock-based compensation awards.

Segment Reporting [Abstract]
Segment Information	Segment Information
	Since the date of the Company’s IPO, the Company has continued its development of internal management reporting. Such development has resulted in changes in the information that is provided to the Company’s chief operating decision maker. Accordingly, during the year ended December 31, 2014, management re-evaluated this information in relation to its definition of its operating segments.
	As a result of this new information provided to the chief operating decision maker, management has concluded that its Mortgage Banking operations should be disclosed as three segments: Originations, Servicing and Financing. Prior period segment disclosures have been restated to conform segment disclosures for the years ended December 31, 2013 and 2012 to those for the year ended December 31, 2014.
	The Originations segment primarily originates and sells residential mortgage loans, which conform to the underwriting guidelines of the GSEs and government agencies and non-agency whole loan investors. The Servicing segment includes loan administration, collection and default activities, including the collection and remittance of loan payments, responding to customer inquiries, collection of principal and interest payments, holding custodial funds for the payment of property taxes and insurance premiums, counseling delinquent mortgagors, modifying loans and supervising foreclosures on the Company’s property dispositions. The Financing segment includes warehouse-lending activities to correspondent customers by the Company’s NattyMac subsidiary, which commenced operations in July 2013.
	The Company's segments are based upon its organizational structure, which focuses primarily on the services performed. The accounting policies of each reportable segment are the same as those of the Company. Certain consolidated back-office operations, such as risk and compliance, human resources, information technology, business processes and marketing, are allocated to each individual segment. Expenses are allocated to individual segments based on the estimated value of services performed, including estimated utilization of square footage and corporate personnel.
	Financial highlights by segment are as follows:

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events
	On January 7, 2015, the Company amended and revised its acknowledgment agreement from Fannie Mae regarding the MSRs borrowing with Barclays. As of this date, the Company can borrow up to 60% of the MSRs value for both Fannie Mae and Freddie MSRs and also, the spread over LIBOR is reduced to 525 basis points for both.
	On January 14, 2015, the Company filed a preliminary prospectus with the Securities and Exchange Commission (the "SEC") under the shelf registration rules that allows the Company to sell from time to time, in one or more offerings, on a continuous or delayed basis, certain securities, such as common stock, debt securities, preferred stock, depository shares, and/or warrants, for an aggregate initial offering price of up to $200,000. In addition, the prospectus registered shares of certain existing shareholders to provide them the opportunity to sell the shares to the public.
	On January 14, 2015, the Company set up a new captive insurance subsidiary, licensed in Michigan, for the purpose of insuring certain employment practices, cyber risk and professional services liability risks of the Company that are currently self-insured or uninsured. By establishing the captive insurance company, the Company, via the new insurance subsidiary, intends to apply for membership to the Federal Home Loan Bank of Indianapolis. Activity in the subsidiary will start in 2015.
	On January 29, 2015, the Company signed a Mortgage Repurchase Agreement with Wells Fargo for $200,000. The borrowing facility is comparable to the repurchase facilities that the Company has in place with other financial institutions, and is designed to finance newly originated conventional, government and jumbo residential mortgages originated or purchased by the Company.  The facility is uncommitted, and the maturity for the facility is January 30, 2016.
	On February 9, 2015, the Company amended and revised its MSRs facility agreement with Merchants to increase the aggregate maximum borrowing capacity from $30,000 to $35,000.
	On February 20, 2015, the Company entered into a letter of intent to sell approximately $3 billion in FNMA and FHLMC MSRs to an unrelated third party.  The anticipated closing date of the transaction is March 31, 2015.

Basis of Presentation and Significant Accounting Policies (Policies)	12 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation: The accompanying consolidated financial statements include the accounts of Stonegate and its subsidiaries and have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) and in accordance with the instructions to Form 10-K as promulgated by the Securities and Exchange Commission. All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates: The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in the Company’s consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly significant relate to the Company’s fair value measurements of mortgage loans held for sale, mortgage servicing rights (“MSRs”), derivative assets and liabilities, goodwill and other intangible assets, as well as its estimates for the reserve for mortgage repurchases and indemnifications and income tax estimates for deferred tax assets valuation allowance considerations.
Risk and Uncertainties	Risks and Uncertainties: In the normal course of business, companies in the mortgage banking industry encounter certain economic and regulatory risks. Economic risks include interest rate risk and credit risk. In a declining interest rate environment, the Company's mortgage origination activities’ results of operations could be positively impacted by higher loan origination volumes and loan margins. In contrast, the Company's results of operations of its mortgage servicing activities could decline due to higher actual and projected loan prepayments related to its loan servicing portfolio. In a rising interest rate environment, the Company's mortgage origination activities' results of operations could be negatively impacted and its mortgage servicing activities’ results of operations to be positively impacted. Credit risk is the risk of default that may result from the borrowers’ inability or unwillingness to make contractually required payments during the period in which loans are being held for sale. The Company manages these various risks through a variety of policies and procedures, such as the hedging of the loans held for sale and interest rate lock commitments using forward sales of MBS, such as To Be Announced (“TBA”) securities, designed to quantify and mitigate the operational and financial risk to the Company to the extent possible. Specifically, the Company engages in hedging of interest rate risk of its mortgage loans held for sale and interest rate lock commitments with the use of TBA securities.
	The Company sells loans to investors without recourse. As such, the investors have assumed the risk of loss or default by the borrower. However, the Company is usually required by these investors to make certain standard representations and warranties relating to credit information, loan documentation and collateral. To the extent that the Company does not comply with such representations, the Company may be required to repurchase the loans or indemnify these investors for any losses from borrower defaults. The Company performs due diligence prior to funding mortgage loans as part of its loan underwriting process, whereby the Company analyzes credit, collateral and compliance risk of all loans in an effort to ensure the mortgage loans the investors’ standards. However, if a loan is repurchased, the Company could incur a loss as part of recording such loan at fair value, which may be less than the amount paid to purchase the loan. In addition, if loans pay off within a specified time frame, the Company may be required to refund a portion of the sales proceeds to the investors.
	The Company’s business requires substantial cash to support its operating activities. As a result, the Company is dependent on its lines of credit and other financing facilities in order to finance its continued operations. If the Company’s principal lenders decided to terminate or not to renew any of these credit facilities with the Company, the loss of borrowing capacity would have a material adverse impact on the Company’s financial statements unless the Company found a suitable alternative source of financing.
Consolidation	Consolidation: The Company’s loans held for sale are sold predominantly to FNMA. The Company also sells loans in GNMA guaranteed mortgage-backed securities (“MBS”) by pooling eligible loans through a pool custodian and assigning rights to the loans to GNMA. FNMA and GNMA provide credit enhancement of the loans through certain guarantee provisions. These securitizations involve variable interest entities (“VIEs”) as the trusts or similar vehicles, by design, that either (1) lack sufficient equity to permit the entity to finance its activities without additional subordinated financial support from other parties, or (2) have equity investors that do not have the ability to make significant decisions relating to the entity’s operations through voting rights, or do not have the obligation to absorb the expected losses, or do not have the right to receive the residual returns of the entity.
	The primary beneficiary of a VIE (i.e., the party that has a controlling financial interest) is required to consolidate the assets and liabilities of the VIE. The primary beneficiary is the party that has both (1) the power to direct the activities of an entity that most significantly impact the VIE’s economic performance; and (2) through its interests in the VIE, the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. The Company typically retains the right to service the loans. Because of the power of FNMA and GNMA over the VIEs that hold the assets from these residential mortgage loan securitizations, principally through its rights and responsibilities as master servicer for FNMA and as approver of issuers for GNMA and the guarantee provisions provided by FNMA and GNMA, the Company is not the primary beneficiary of the VIEs and therefore the VIEs are not consolidated by the Company.
	The Company has concluded that on a consolidated basis it has a variable interest in NattyMac Funding ("NMF") resulting from any potential interest it may earn from the 49% NMF earnings participation, as described in Note 12, "Debt".  The Company has further concluded that it is not considered the primary beneficiary of its variable interest in NMF based on the fact that  it does not have the power to direct the activities of NMF that most significantly impact NMF’s economic performance.  NMF has the final authority over its operating policies.  If at any time in the future the Company claims the right to the common capital stock of NMF in a default scenario as described, the primary beneficiary conclusion may change.  The Company believes that its maximum exposure to loss as a result of this arrangement is the $30,000 in subordinated loan receivable as of December 31, 2014.
	The Company performs on-going reassessments of: (1) whether entities previously evaluated under the majority voting-interest framework have become VIEs, based on certain events, and therefore become subject to the VIE consolidation framework; and (2) whether changes in the facts and circumstances regarding the Company’s involvement with a VIE cause the Company’s consolidation determination to change.
Revenue Recognition	Revenue Recognition:
	Mortgage Loans Held for Sale: Loan originations that are intended to be sold in the foreseeable future, including residential mortgages, are reported as mortgage loans held for sale. Mortgage loans held for sale are carried at fair value under the fair value option with changes in fair value recognized in current period earnings. At the date of funding of the mortgage loan held for sale, the funded amount of the loan, the related derivative asset or liability of the associated interest rate lock commitment, less direct loan costs (including but not limited to correspondent fees, broker premiums and underwriting expenses) becomes the initial recorded investment in the mortgage loan held for sale. Such amount approximates the fair value of the loan.
	Mortgage loans held for sale are considered de-recognized, or sold, when the Company surrenders control over the financial assets. Control is considered to have been surrendered when the transferred assets have been isolated from the Company, beyond the reach of the Company and its creditors; the purchaser obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets; and the Company does not maintain effective control over the transferred assets through an agreement that both entitles and obligates the Company to repurchase or redeem the transferred assets before their maturity or the ability to unilaterally cause the holder to return specific assets. Such transfers may involve securitizations, participation agreements or repurchase agreements. If the criteria above are not met, such transfers are accounted for as secured borrowings, in which the assets remain on the balance sheet, the proceeds from the transaction are recognized as a liability and no MSRs are recorded for those transferred loans.
	Gains and losses from the sale of mortgages are recognized based upon the difference between the sales proceeds and carrying value of the related loans upon sale and is recorded in gains on mortgage loans held for sale in the statement of operations. The sales proceeds reflect the cash received and the initial fair value of the separately recognized mortgage servicing rights less the fair value of the liability for mortgage repurchases and indemnifications. Gain on mortgage loans held for sale also includes the unrealized gains and losses associated with the mortgage loans held for sale and the realized and unrealized gains and losses from derivatives.
	Sale of Mortgage Servicing Rights: The Company occasionally sells a certain portion of its MSRs. At the time of the sale, based on the structure of the arrangement, the Company typically records a gain or loss on such sale based on the selling price of the MSRs less the carrying value and transaction costs. The MSRs are sold in separate transactions from the sale of the underlying loans. The MSRs sales are assessed to determine if they qualify as a sale transaction. A transfer of servicing rights related to loans previously sold qualifies as a sale at the date on which title passes, if substantially all risks and rewards of ownership have irrevocably passed to the transferee and any protection provisions retained by the transferor are minor and can be reasonably estimated. In addition, if a sale is recognized and only minor protection provisions exist, a liability should be accrued for the estimated obligation associated with those provisions. As MSRs are not considered financial assets for accounting purposes, the accounting model used to determine if the transfer of an MSRs asset qualifies as a sale is based on a risks and rewards approach. Upon completion of a sale, the Company would account for the transaction as a sale and derecognize the mortgage servicing rights from the Consolidated Balance Sheets.
	Mortgage Servicing Rights and Change in Mortgage Servicing Rights Valuation: The Company capitalizes MSRs at fair value when purchased or at the time the underlying loans are de-recognized, or sold, and when the Company retains the right to service such loans. To determine the fair value of the MSRs, the Company uses a valuation model that calculates the present value of future cash flows from servicing. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, including estimates of the cost of servicing, the discount rate, float value, the inflation rate, estimated prepayment speeds, and default rates. MSRs currently are not actively traded in the markets, accordingly, considerable judgment is required to estimate their fair value and the exercise of that judgment can materially impact current period earnings.
	For periods prior to January 1, 2013, the Company accounted for the subsequent measurement of its MSRs at the lower of amortized cost or fair value. Effective January 1, 2013, the Company elected to irrevocably account for the subsequent measurement of its existing MSRs using the fair value method, whereby the subsequent changes in the fair value of the MSRs are recorded in earnings during the period in which the changes occur. Under the fair value method, the fair value of the Company's originated mortgage loans class of MSRs is assessed at each reporting date using the methods described above. In accordance with the applicable GAAP guidance, this change in accounting principle was accounted for on a prospective basis (financial statement periods prior to 2013 were not restated). The Company did not record a cumulative-effect adjustment to retained earnings as of January 1, 2013, as the net amortized carrying value of the MSRs as of January 1, 2013 equaled the fair value at such date due to MSRs impairment charges recorded during 2012.
	Loan Origination and Other Loan Fees: Loan origination and other loan fee income represents revenue earned from originating mortgage loans. Loan origination and other loan fees generally represent flat, per-loan fee amounts and are recognized as revenue, net of loan origination costs (excluding those direct loan origination costs that are recorded as a component of the recorded investment in mortgage loans held for sale), at the time the loans are funded.
	Loan Servicing Fees: Loan servicing fee income represents revenue earned for servicing mortgage loans. The servicing fees are based on a contractual percentage of the outstanding principal balance and recognized as revenue as the related mortgage payments are collected. Corresponding loan servicing costs are charged to expense as incurred.
	Interest Income: Interest income on mortgage loans is accrued to income based upon the principal amount outstanding and contractual interest rates. Income recognition is discontinued when loans become 90 days delinquent or when in management’s opinion, the collectability of principal and income becomes doubtful.
Warehouse Lending Receivables	Warehouse Lending Receivables: During the year ended December 31, 2013, the Company introduced its warehouse lending products to its correspondent customers through warehouse line of credit agreements. Under the warehouse line of credit agreements, the Company lends funds to its correspondent customers to finance those correspondents' mortgage loan originations. The correspondent customers pledge, as security to the Company, the underlying mortgage loans, and pay interest on the related outstanding borrowings at a specified interest rate plus a margin, as defined in the underlying line of credit agreements with each correspondent customer. As of December 31, 2014, the Company had outstanding warehouse lending receivables from its correspondent customers of $85,431 and recognized interest income from its warehouse lending activities of $2,812 during the year ended December 31, 2014. As of December 31, 2013, the Company had outstanding warehouse lending receivables from its correspondent customers of $12,089 and recognized interest income from its warehouse lending activities of $92 during the year ended December 31, 2013. The Company periodically reviews the counterparties and warehouse lending receivables for collectability based on historical collection trends and management judgment regarding the ability to collect specific accounts and has determined that no allowance for doubtful accounts was necessary as of December 31, 2014 or December 31, 2013.
Derivative Financial Instruments	Derivative Financial Instruments: All derivative financial instruments are recognized as either assets or liabilities and measured at fair value. The Company accounts for all of its derivatives as free-standing derivatives and does not designate any for hedge accounting. Therefore, the gain or loss resulting from the change in the fair value of the derivative is recognized in the Company’s results of operations during the period of change.
	The Company enters into commitments to originate residential mortgage loans held for sale, at specified interest rates and within a specified period of time, with customers who have applied for a loan and meet certain credit and underwriting criteria (interest rate lock commitments). These interest rate lock commitments (“IRLCs”) meet the definition of a derivative financial instrument and are reflected in the balance sheet at fair value with changes in fair value recognized in current period earnings. Unrealized gains and losses on the IRLCs are recorded as derivative assets and derivative liabilities, respectively, and are measured based on the value of the underlying mortgage loan, quoted MBS prices, estimates of the fair value of the mortgage servicing rights and the probability that the mortgage loan will fund within the terms of the interest rate lock commitment, net of estimated commission expenses.
	The Company manages the interest rate and price risk associated with its outstanding IRLCs and loans held for sale by entering into derivative instruments such as forward loan sales commitments and mandatory delivery commitments. Management expects these derivatives will experience changes in fair value opposite to changes in fair value of the IRLCs and loans held for sale, thereby reducing earnings volatility. The Company takes into account various factors and strategies in determining the portion of the mortgage pipeline (IRLCs) and loans held for sale it wants to economically hedge.
Reserve for Loan Repurchases and Indemnifications	Reserve for Loan Repurchases and Indemnifications: Loans sold to investors by the Company and which met investor and agency underwriting guidelines at the time of sale may be subject to repurchase or indemnification in the event of specific default by the borrower or subsequent discovery that underwriting standards were not met. The Company may, upon mutual agreement, agree to repurchase the loans or indemnify the investor against future losses on such loans. In such cases, the Company bears any subsequent credit loss on the loans. The Company has established an initial reserve liability for expected losses related to these representations and warranties at the date the loans are de-recognized from the balance sheet based on the fair value of such reserve liability. Subsequently, based on changing facts and circumstances or changes in certain estimates and assumptions, the reserve liability is adjusted with a corresponding amount recorded to provision for reserve for mortgage repurchases and indemnifications. In assessing the adequacy of the reserve, management evaluates various factors including actual losses on repurchases and indemnifications during the period, historical loss experience, known delinquent and other problem loans, delinquency trends in the portfolio of sold loans and economic trends and conditions in the industry. Actual losses incurred are reflected as charge-offs against the reserve liability.
	Loans Eligible for Repurchase from GNMA: When the Company has the unilateral right to repurchase GNMA pool loans it has previously sold (generally loans that are more than 90 days past due), the Company then records the loan on its balance sheet. The recognition of previously sold loans does not impact the accounting for the previously recognized mortgage servicing rights.
Servicing Advances	Servicing Advances: Servicing advances represent escrows and advances paid by the Company on behalf of customers and investors to cover delinquent balances for property taxes, insurance premiums and other out-of-pocket costs. Advances are made in accordance with the servicing agreements and are recoverable upon collection of future borrower payments or foreclosure of the underlying loans. The Company periodically reviews these receivables for collectability and amounts are written off when they are deemed uncollectible.
Property and Equipment	Property and Equipment: Property and equipment is recorded at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over estimated useful lives of one to three years for internally developed computer software, three to ten years for furniture and equipment and three to five years for purchased computer software and equipment. Leasehold improvements are amortized using the straight-line method over the shorter of the related lease term or their estimated economic useful lives.
	The Company periodically assesses property and equipment for recoverability whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. If management identifies an impairment indicator, it assesses recoverability by comparing the carrying amount of the asset to the undiscounted cash flows expected to result from the use and eventual disposition of the asset. An impairment loss is recognized in earnings whenever the carrying amount is not recoverable.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets: Business combinations are accounted for using the acquisition method of accounting. Acquired intangible assets are recognized and reported separately from goodwill. Goodwill represents the excess cost of acquisition over the fair value of net assets acquired. Finite-lived purchased intangible assets consist of the Crossline trade name, customer relationships, non-compete agreement, an active agent list and state licenses, which have useful lives of four years, eight years, three years, five years and one year, respectively. Intangible assets with finite lives are amortized over their estimated lives using an amortization method that reflects the pattern in which the economic benefits of the asset are consumed. The Company evaluates the estimated remaining useful lives on intangible assets to determine whether events or changes in circumstances warrant a revision to the remaining periods of amortization. If an intangible asset’s estimated useful life is changed, the remaining net carrying amount of the intangible asset is amortized prospectively over that revised remaining useful life. Additionally, an intangible asset that initially is deemed to have a finite useful life would cease being amortized if it is subsequently determined to have an indefinite useful life. Such intangible assets are then tested for impairment. The Company reviews such intangibles for impairment whenever events or changes in circumstances indicate their carrying amounts may not be recoverable, in which case any impairment charge would be recorded to earnings. Given the formation of Stonegate Direct in October 2014, which was integrated through the call center operations of Crossline, the Company determined there was a significant change in the manner in which the Crossline trade name was used and as a result determined the change to be a triggering event for an impairment analysis to be performed in accordance with the guidance of long-lived assets. As of December 31, 2014, the Crossline trade name had no carrying value on its Consolidated Balance Sheet.
	Indefinite-lived purchased intangible assets consist of the NattyMac trade name. Goodwill and other intangible assets with an indefinite useful life are not subject to amortization but are reviewed for impairment annually or more frequently whenever events or changes in circumstances indicate that the carrying amount of an intangible asset may not be recoverable. For indefinite-lived intangible assets other than goodwill, the Company first assesses qualitative factors to determine whether the existence of events or circumstances leads to a determination that is more likely than not the assets are impaired. If the Company determines that it is more likely than not that the intangible assets are impaired, a quantitative impairment test is performed. For the quantitative impairment test, the Company estimates and compares the fair value of indefinite-lived intangible asset with its carrying amount. If the carrying amount of the indefinite-lived intangible asset exceeds its fair value, the amount of the impairment is measured as the difference between the carrying amount of the asset and its fair value. Impairment is permanently recognized by writing down the asset to the extent that the carrying value exceeds the estimated fair value.
	For goodwill, the Company first performs a quantitative impairment test. At the operating segment level, which is the reporting unit, the Company estimates and compares the fair value to the book value. If the segment's book value exceeds its fair value, the Company then performs a hypothetical purchase price allocation for the segment. This is done by marking all assets and liabilities to fair value and calculating an implied goodwill value. If the implied goodwill value is less than the carrying value of the goodwill, the amount of impairment is measured as the difference and is permanently recognized by writing down the goodwill to the extent the carrying value exceeds the implied value.
Stock-Based Compensation	Stock-Based Compensation: The Company grants stock options and restricted stock units to certain executive officers, key employees and independent directors. Stock options have been granted for a fixed number of shares with an exercise price at least equal to the fair value of the shares at the date of grant. Restricted stock units have been granted for a fixed number of shares with a fair value equal to the fair value of the Company's common stock on the grant date. The stock options and restricted stock units granted are recognized as compensation expense in the statement of operations based on their grant-date fair values.
Advertising and Marketing	Advertising and Marketing: The Company uses primarily print, broadcast and web-based advertising and marketing to promote its products.
Income Taxes	Income Taxes: Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. There was no such need for a valuation allowance as of December 31, 2014 and 2013. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.
	The Company’s income tax expense includes assessments related to uncertain tax positions taken or expected to be taken by the Company. Management has concluded that it currently does not have any significant uncertain tax positions. If applicable, the Company will recognize interest and penalties related to unrecognized tax benefits as a component of income tax expense. The open tax years subject to examination by taxing authorities include the years ended December 31, 2013, 2012 and 2011.
Cash and Cash Equivalents	Cash and Cash Equivalents: The Company classifies cash and temporary investments with original maturities of three months or less as cash and cash equivalents, which totaled $45,382 and $43,104 at December 31, 2014 and 2013, respectively. The Company typically maintains cash in financial institutions in excess of FDIC limits. The Company evaluates the creditworthiness of these financial institutions in determining the risk associated with these cash balances.
Restricted Cash	Restricted Cash: The Company maintains certain cash balances that are restricted under broker margin account agreements associated with its derivative activities.
Recent Accounting Developments	Recent Accounting Developments: ASU No. 2014-04, "Receivables--Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans Upon Foreclosure," was issued in January 2014. This update clarifies when a creditor is considered to have received physical possession of residential real estate property collateralized by a consumer mortgage loan in order to reduce diversity in practice for when a creditor derecognizes the loan receivable and recognizes the real estate property. The guidance in ASU No. 2014-04 also requires interim and annual disclosure of the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure. The new guidance will be effective for the Company beginning on January 1, 2015. The Company does not expect the adoption of the new guidance to have a material impact on its financial statements.
	ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)" was issued in May 2014. This update supersedes the revenue recognition criteria and amends existing requirements in other Topics to be consistent with the new recognition and measurement rules. This update is to ensure that an entity is recognizing revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new guidance will be effective for the Company beginning on January 1, 2017. The Company is currently evaluating the guidance under ASU 2014-09 and has not yet determined the impact, if any, on its consolidated financial statements.
	ASU No. 2014-11, "Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures," was issued in June 2014. The pronouncement in this update changes the accounting for repurchase-to-maturity transactions and linked repurchase financings to secured borrowing accounting, which is consistent with the accounting for other repurchase agreements. The pronouncement also requires two new disclosures. The first disclosure requires an entity to disclose information on transfers accounted for as sales in transactions that are economically similar to repurchase agreements. The second disclosure provides increased transparency about the types of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. The new guidance will be effective for the Company beginning on January 1, 2015. The Company does not expect the adoption of the new guidance to have a material impact on its financial statements.
	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" was issued in June 2014. This update addresses how entities commonly issue share-based payment awards that require a specific performance target to be achieved in order for employees to become eligible to vest in the awards. Current US GAAP does not contain explicit guidance on how to account for those share-based payments. This update is intended to resolve the diverse accounting treatment of those awards in practice. The new guidance will be effective for the Company beginning on January 1, 2015. The Company does not expect the adoption of the new guidance to have a material impact on its financial statements.
	ASU No. 2014-14, "Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40) -Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure" was issued in August 2014. This update requires certain government-guaranteed mortgage loans to be reclassified to a separate other receivable at the time of foreclosure. The new guidance will be effective for the Company beginning on January 1, 2015. The Company does not expect the adoption of the new guidance to have a material impact on its financial statements.
	ASU No. 2014-15, "Presentation of Financial Statements - Going Concern (Topic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern" was issued in August 2014. This update is intended to define management's responsibility to evaluate whether there is a substantial doubt about an organization's ability to continue as a going concern and to provide related footnote disclosure. The new guidance will be effective for the Company beginning on January 1, 2016. The Company does not expect the adoption of the new guidance to have a material impact on its financial statements.
	ASU No. 2014-17, "Business Combinations (Topic 805) - Pushdown Accounting" was issued in November 2014. This update provides an acquired entity with an option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. An acquired entity may elect the option to apply pushdown accounting in the reporting period in which the change-in-control events occurs. The new guidance will be effective for the Company on the date of its next business combination. The Company does not expect the adoption of the new guidance to have a material impact on its financial statements.
	ASU No. 2015-02, "Consolidation (Topic 810) - Amendments to the Consolidation Analysis" was issued in February 2015. This update affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. The amendments in this update affect the following areas: 1) limited partnerships and similar legal entities, 2) evaluating fees paid to a decision maker or a service provider as a variable interest, 3) the effect of fee arrangements on the primary beneficiary determination, 4) the effect of related parties on the primary beneficiary determination, and 5) certain investment funds. The new guidance will be effective for the Company beginning on January 1, 2016. The Company does not expect the adoption of the new guidance to have a material impact on its financial statements.

Fair Value Measurements	Fair Value Measurements
	The Company uses fair value measurements in fair value disclosures and to record certain assets and liabilities at fair value on a recurring basis, such as MSRs, derivatives and loans held for sale, or on a nonrecurring basis, such as when measuring intangible assets and long-lived assets. The Company has elected fair value accounting for loans held for sale to more closely align the Company’s accounting with its interest rate risk strategies without having to apply the operational complexities of hedge accounting.
	The Company groups its assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:
	Level Input:	Input Definition:
	Level 1	Unadjusted, quoted prices in active markets for identical assets or liabilities.
	Level 2	Prices determined using other significant observable inputs. Observable inputs are inputs that other market participants would use in pricing an asset or liability and are developed based on market data obtained from sources independent of the Company. These may include quoted prices for similar assets and liabilities, interest rates, prepayment speeds, credit risk and others.
	Level 3	Prices determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity), unobservable inputs may be used. Unobservable inputs reflect the Company's own assumptions about the factors that market participants would use in pricing the asset or liability, and are based on the best information available in the circumstances.
	An asset or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.
	While the Company believes its valuation methods are appropriate and consistent with those used by other market participants, the use of different methods or assumptions to estimate the fair value of certain financial statement items could result in a different estimate of fair value at the reporting date. Those estimated values may differ significantly from the values that would have been used had a readily available market for such items existed, or had such items been liquidated, and those differences could be material to the consolidated financial statements.
	Management incorporates lack of liquidity into its fair value estimates based on the type of asset or liability measured and the valuation method used. The Company uses discounted cash flow techniques to estimate fair value. These techniques incorporate forecasting of expected cash flows discounted at appropriate market discount rates that are intended to reflect the lack of liquidity in the market.
	The following describes the methods used in estimating the fair values of certain financial statement items:
	Mortgage Loans Held for Sale: The Company's mortgage loans held for sale at fair value are saleable into the secondary mortgage markets and their fair values are estimated using observable quoted market or contracted prices or market price equivalents, which would be used by other market participants.
	Derivative Financial Instruments: The Company estimates the fair value of interest rate lock commitments based on the value of the underlying mortgage loan, quoted MBS prices and estimates of the fair value of the MSRs and the probability that the mortgage loan will fund within the terms of the interest rate lock commitment. The Company estimates the fair value of forward sales commitments based on quoted MBS prices.
	Mortgage Servicing Rights: The Company uses a discounted cash flow approach to estimate the fair value of MSRs. This approach consists of projecting servicing cash flows discounted at a rate that management believes market participants would use in their determinations of value. The Company obtains valuations from an independent third party on a monthly basis, to support the reasonableness of the fair value estimate generated by the internal model. The key assumptions used in the estimation of the fair value of MSRs include prepayment speeds, discount rates, default rates, cost to service, contractual servicing fees and escrow earnings. In valuing the fair value of MSRs, the Company uses a forward yield curve as an input which will impact pre-pay estimates and the value of escrows as compared to a static forward yield curve. The Company believes that the use of the forward yield curve better represents fair value of MSRs because the forward yield curve is the market’s expectation of future interest rates based on its expectation of inflation and other economic conditions.
