Organization, Consolidation and Presentation of Financial Statements [Abstract]
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 in 2009, the Company is now an Ohio corporation. The Company’s headquarters is in Indianapolis, Indiana.
	The Company is a non-bank integrated mortgage company focused on the U.S. residential mortgage market and is comprised of three operating segments: Originations, Servicing and Financing. 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 how the chief operating decision maker evaluates the performance of the business.
	The Company originates, acquires, sells, finances and services residential mortgage loans. The Company predominantly sells mortgage loans to the Federal National Mortgage Association (“Fannie Mae” or “FNMA”), to the Federal Home Loan Mortgage Corporation (“Freddie Mac” or “FHLMC”), to financial institution secondary market investors and in Government National Mortgage Association (“Ginnie Mae” or “GNMA”) pools of mortgage backed securities (“MBS”). Both FNMA and FHLMC are considered government-sponsored enterprises ("GSEs"). 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 Company’s integrated and scalable residential mortgage banking platform enables us to efficiently and effectively originate, acquire, sell, finance and service residential mortgage loans. The Company’s platform and operating model provides its constituents visibility and access to essential data, documents and analytics related to the loan and originator performance over time. 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 principal sources of revenue include (i) gain on sale 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.

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. The Company is subject to interest rate risk to the extent that in a rising interest rate environment, the Company may experience a decrease in loan production, as well as decreases in the value of mortgage loans held for sale and in commitments to originate loans, which may negatively impact the Company’s operations. Conversely, in a decreasing interest rate environment, the value of the Company’s MSRs may decrease, which could negatively impact the Company’s operations. 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 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 transfers 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 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: 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 gain 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.
	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 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 MSR 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 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, 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, 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.
	To the extent derivatives subject to master netting arrangements meet applicable requirements, the Company presents the derivative balances and related cash collateral amounts net on the balance sheet.
	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. As of December 31, 2013 and 2012, delinquent or defaulted mortgage loans currently in GNMA pools that the Company had recognized as a liability on its consolidated balance sheets totaled $26,268 and $7,116, respectively.
	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, 2013 and 2012, the Company had recognized an asset for servicing advances on its consolidated balance sheet of $4,177 and $938, 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 three to ten years for furniture and equipment and three years for computer software. Leasehold improvements are amortized using the straight-line method over the shorter of the related lease term or their estimated economic useful lives.
	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 a 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 a straight line amortization method. 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 asset is 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 an impairment charge would be recorded to earnings.
	Indefinite-lived purchased intangible assets consist of trade names. 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. 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 that goodwill or other indefinite-lived intangible assets are impaired. If the Company determines that it is more likely than not that goodwill or other intangible assets are impaired, a quantitative impairment test is performed. For the quantitative impairment test, the Company estimates and compares the fair value of the goodwill or indefinite-lived intangible asset with its carrying amount. If the carrying amount of the goodwill or other 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.
	Long-Lived Assets: The Company periodically assesses long-lived assets, including property and equipment and definite-lived intangible assets, 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, 2013, 2012 and 2011.
	Investment in Closely Held Entity: Investment in closely held entity consists of shares of voting common and preferred stock, which the Company owns in a non-publicly traded entity. The investment is carried at cost as the Company does not exercise significant influence over the entity’s operating and financial activities. The Company periodically evaluates this investment for impairment and no impairment charges were recorded during the years ended December 31, 2013, 2012 and 2011.
	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 $2,317, $1,059 and $414 for the years ended December 31, 2013, 2012 and 2011.
	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. 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, 2011, 2010, and 2009. The Company had no federal or state tax examinations in process as of December 31, 2013.
	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 $43,104 and $15,056 at December 31, 2013 and 2012, 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.
	Off-Balance Sheet Arrangements: As of December 31, 2013, the Company did not have any off-balance sheet arrangements.
	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 is currently evaluating the guidance under ASU 2014-04 and have not yet determined the impact, if any, on its consolidated financial statements.
	ASU No. 2013-01, “Balance Sheet (Topic 210): Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities” was issued in January 2013. This update clarifies the scope of transactions that are subject to the disclosures about offsetting, specifically that ordinary trade receivables and receivables are not in the scope of ASU No. 2011-11. ASU No. 2011-11 applies only to derivatives, repurchase agreements and reverse purchase agreements, and securities borrowing and securities lending transactions that are offset in accordance with specific criteria contained in FASB Accounting Standards Codification or subject to a master netting arrangement or similar agreement. ASU 2013-01 is effective for fiscal years beginning on or after January 1, 2013, and interim periods within those annual periods. The adoption of ASU 2013-01 did not materially impact the Company’s consolidated financial statements.
	Prior Period Reclassifications: Certain prior period amounts have been reclassified to conform to the current period presentation.

	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 will allow the Company to increase its origination volume through geographic expansion. Crossline is 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 operates two national mortgage origination call centers in Lake Forest, CA and Scottsdale, AZ and also operates retail mortgage origination branches in seven other locations in Southern California.
	The following table summarizes the total consideration transferred to acquire Crossline and the preliminary 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	2,333
	Total fair value of assets acquired	36,963
	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	7,833
	Preliminary goodwill	$	3,638
	Acquisition-related expenses	$	122
	The excess of the aggregate consideration transferred over the fair value of the identified net assets acquired resulted in preliminary, tax-deductible goodwill of $3,638 as of December 31, 2013. Preliminary 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. Any additional payments or receipts of cash resulting from contractual purchase price adjustments or any subsequent adjustments made to the preliminary acquisition-date fair values of the assets acquired or liabilities assumed during the measurement period will be recorded as an adjustment to goodwill.
	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, an asset volatility factor of 18.70% and (iii) a discount rate of 6.50%.
	Of the $2,204 of total acquired intangible assets, $1,720 was assigned to trade name, which has an estimated life of four years, $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 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.
	The results of operations of Crossline for the period following December 19, 2013 are included in our consolidated financial statements and represented $612 and $55 of the Company’s total revenues and net income, respectively, for the year ended December 31, 2013.
	The following unaudited pro forma information includes the results of operations for Crossline for the periods prior to the acquisition, adjusted for the elimination of intercompany activity, reduced interest income related to the cash used to fund the acquisition, reduced interest income related to the cash dividend made to Crossline's seller immediately prior to the closing of the acquisition, additional amortization related to intangible assets acquired and the related income tax effects. The unaudited pro forma financial information is presented for informational purposes only and may not be indicative of the results of operations had Crossline been owned by the Company for the full years ended December 31, 2013, 2012 or 2011, nor is it necessarily indicative of future results of operations. The following summary of unaudited pro forma financial information presents revenues, net income and per share amounts of the Company as if the acquisition of Crossline had occurred on January 1, 2011.

	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, will complement the Company’s existing business and allow 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
	Fair value of contingent consideration	2,095
	Total consideration	2,607
	Fair value of assets acquired:
	Identified intangible assets	3,710
	Property and equipment	57
	Other assets	12
	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 $2,085 and $2,095 as of December 31, 2013 and December 31, 2012, respectively, and was estimated by applying the income approach. The fair value of the contingent consideration as of December 31, 2013 and December 31, 2012 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 5.37% and 5.30%, respectively. The Company’s revised estimated fair value of the contingent earn-out liability of $2,085 as of December 31, 2013 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, 2013, 383 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 two-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 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, 2013 and December 31, 2012, counterparties held $730 and $3,445, 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 $3,520 and $1,787 at December 31, 2013 and 2012, respectively, to those counterparties. For the years ended December 31, 2013 and 2012, the Company incurred no credit losses due to non-performance of any of its counterparties.

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 MSR asset is capitalized, which represents the current fair value of the future net cash flows 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 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.
	On November 1, 2013, the Company purchased an MSR portfolio with an unpaid principal balance ("UPB") of $142,219 from an unrelated third party, for a total cash purchase price of $1,543. The MSRs purchased have substantially similar attributes to the Company's existing MSRs created through its own mortgage loan originations with respect to note rates, credit quality and loan types. The Company is continuing to service the underlying mortgage loans and accounts for the purchased MSRs using the fair value method.
	The Company’s total mortgage servicing portfolio at December 31, 2013 and 2012 is summarized as follows (based on the UPB of the underlying mortgage loans):
		December 31,
		2013			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 (beginning January 1, 2013), derivatives and loans held for sale, or on a nonrecurring basis, such as when measuring MSRs upon initial recognition and measuring impairments on MSRs (for periods prior to January 1, 2013), 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 quoted market or contracted prices or market price equivalents.
	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 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.
	The following are the major categories of assets and liabilities measured at fair value on a recurring basis as of December 31, 2013:

2 Contingent consideration liabilities resulted from the Company’s acquisition of Crossline during December 2013 and its purchase of assets from NattyMac during August 2012. See Note 4 “Business Combinations” for additional information related to these business combinations and contingent consideration arrangements.
There were no liabilities measured at fair value on a recurring basis using Level 3 inputs during the year ended December 31, 2011.
Transfers between levels, if any, are recorded as of the beginning of the reporting period. For the years ended December 31, 2013, 2012 and 2011 there were no 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 acquisitions of Crossline, Nationstar and NattyMac on December 19, 2013, November 29, 2013 and August 30, 2012, respectively. The values of the net assets acquired in these acquisitions and resulting goodwill and other intangible assets were recorded at fair value using Level 3 inputs. Refer to Note 4, "Business Combinations", for further information regarding the methodologies and key assumptions used in the acquisition date fair value estimates.
Fair Value of Other Financial Instruments
As of December 31, 2013 and December 31, 2012, all financial instruments were either recorded at fair value or the carrying value approximated fair value. For financial instruments such as cash, restricted cash, servicing advances, secured borrowings, mortgage repurchase 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.

Estimated future amortization expense for each of the years ended December 31, is as follows: 2014, $1,020; 2015, $916; 2016, $916; 2017, $768; 2018, $294; thereafter, $490. Estimated amortization expense was based on existing intangible asset balances as of December 31, 2013. Actual amortization expense may vary from these estimates.
	The Company completed its first annual impairment test of existing other intangible assets with indefinite lives during the year ended December 31, 2013 (as of October 1, 2013), and no impairment losses were incurred. This test involved the use of estimates related to the fair value of the other intangible assets with indefinite lives, and require a significant degree of judgment and the use of subjective assumptions. The fair value of the other intangible asset tested for impairment (trade name) was determined using a discounted cash flow method. This method required management to make internal estimates related to future revenues, expenses and income tax rates, which were considered Level 3 inputs. As the Company's goodwill was measured at fair value as of December 18, 2013 (the date of its acquisition of Crossline), goodwill was not tested for impairment during the year ended December 31, 2013. The Company will complete its first annual impairment test of goodwill 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 sold to FNMA, FHLMC and to secondary market investors, 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. Mortgage loans sold to secondary market investors, such as financial institutions, are generally sold on a servicing released basis whereby the Company does not retain the related MSRs. 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.
	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. All mortgage participation and repurchase agreements are accounted for by the Company as secured borrowings.
	The following table sets forth information regarding cash flows for the years ended December 31, 2013 and 2012 relating to loan sales in which the Company has continuing involvement:

	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, 2013, 2012 and 2011 are as follows:

		2013		2012	2011

	1 Represents older, higher interest rate loans acquired from the Company's merger with Swain in 2009.
	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 MSR 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. Conversely, when mortgage rates increase, MSRs generally increase in value, as borrowers tend not to refinance their loans and the estimated life of those loans increases.
	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.  In the MSRs valuation as of December 31, 2013, the Company’s assumptions for default rates for FNMA, GNMA and FHLMC mortgage loans were 3.97%, 6.44% and 3.82%, respectively. In the MSRs valuation as of December 31, 2012, the Company's assumptions for default rates for FNMA and GNMA were 2.37%, and 5.41%, respectively (there were no MSRs related to FHLMC mortgage loans as of December 31, 2012). The default rates represent the Company’s estimate of the loans 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 assumptions used in valuing the MSRs.
	The hypothetical effect of an adverse change in these key assumptions would result in a decrease in fair values of the Company's MSRs as follows as of December 31, 2013 and 2012:
		December 31,
		2013			2012
	Discount rates:
	Impact of discount rate + 1%	$	(8,706	)	$	(2,071	)
	Impact of discount rate + 2%	$	(16,638	)	$	(3,953	)
	Impact of discount rate + 3%	$	(23,889	)	$	(5,671	)
	Prepayment speeds:
	Impact of prepayment speed * 105%	$	(3,558	)	$	(1,278	)
	Impact of prepayment speed * 110%	$	(7,003	)	$	(2,505	)
	Impact of prepayment speed * 120%	$	(13,570	)	$	(4,819	)
	Cost of servicing:
	Impact of cost of servicing * 105%	$	(1,157	)	$	(415	)
	Impact of cost of servicing * 110%	$	(2,314	)	$	(830	)
	Impact of cost of servicing * 120%	$	(4,629	)	$	(1,659	)
	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 MSR 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 MSR 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.

	Mortgage Funding Arrangements
	The Company maintains mortgage participation agreements, repurchase agreements and warehouse lines of credit(collectively referred to as “mortgage funding arrangements”) with various financial institutions, primarily to fund the origination of mortgage loans which are subject to participation. As of December 31, 2013 the Company held mortgage funding arrangements with 5 separate financial institutions and a total maximum borrowing capacity of $967,000. Each mortgage funding arrangement is collateralized by the underlying mortgage loans.
	The following table summarizes the amounts outstanding, interest rates and maturity dates under the Company’s various mortgage funding arrangements as of December 31, 2013:
	Mortgage Funding Arrangements		Amount Outstanding			Interest Rate	Maturity Date
	Merchants Bank of Indiana		$	343,433		Same as the underlying mortgage rates, less contractual service fee/PRIME plus 1.00%	Jun-14

	First Tennessee Bank		4,608			LIBOR plus applicable margin	Aug-14
	Total		$	572,562
	The mortgage funding arrangements are generally tied to the loan participation agreements executed with the same financial institutions. Pursuant to the loan participation agreements, the Company periodically sells beneficial ownership interests in its mortgage loan receivables. As of December 31, 2013, the Company has a total of $400,000 in loan participation limit that expires through June 30, 2014. The lenders may cancel the agreements with written notice; however, we expect to be able to renew these agreements and do not foresee any challenges in doing so.
	On July 1, 2013, we entered into an amended and restated master participation agreement with Merchants Bank of Indiana. Merchants Bank of Indiana’s commitment to purchase mortgage loans pursuant to the amended and restated master participation agreement will expire on June 30, 2014, unless renewed or terminated earlier under certain circumstances provided for therein. Such amended and restated master participation agreement provides that we may, from time to time, transfer to Merchants Bank of Indiana undivided beneficial ownership interests in qualifying, single-family mortgage loans. The aggregate maximum borrowing capacity under the amended and restated master participation agreement was $400,000 at December 31, 2013. Amounts outstanding under this agreement totaled $342,393 at December 31, 2013.
	In May 2011, we entered into a mortgage warehouse and security agreement with Merchants Bank of Indiana, which was amended and restated in June 2013. The mortgage warehouse loan and security agreement states that Merchants Bank of Indiana will establish a line of credit for us secured by our pledge of certain residential mortgage loans and the related mortgage documents to Merchants Bank. The maximum borrowing capacity under the line of credit was $2,000 at December 31, 2013. At December 31, 2013, $1,040 was outstanding under this line of credit and carried an interest rate of 4.25%.
	On July 31, 2013, we entered into a master repurchase agreement with Barclays Bank PLC ("Barclays"), which was amended and restated in December 2013. The master repurchase agreement will terminate at the earliest to occur of (1) December 16, 2014, (ii) the termination of the mortgage loan participation purchase and sale agreement with Barclays or (iii) at the option of Barclays, the occurrence of an event of default after the expiration of any applicable grace period. The master repurchase agreement states that we may, from time to time, enter into transactions in which we sell to Barclays certain mortgage loans, on a servicing-released basis, against the transfer of funds by Barclays, with a simultaneous agreement for Barclays to transfer to us the related purchased assets on a date certain not later than one year following such transfer, against the transfer of funds by us. The interest rate is equal to LIBOR plus a margin.
	On July 31, 2013, we entered into a mortgage loan participation purchase and sale agreement with Barclays, which was amended and restated in December 2013. The mortgage loan participation purchase and sale agreement will terminate at the earliest to occur of (i) December 16, 2014, (ii) the termination of the master repurchase agreement with Barclays or, (iii) at the option of Barclays, the occurrence of a servicing termination event after the expiration of any applicable grace period. The mortgage loan participation purchase and sale agreement states that we may, from time to time, sell all of our beneficial right, title and interest in and to designated pools of single-family residential mortgage loans eligible in the aggregate to back securities, and in and to the servicing rights related thereto. The aggregate transaction limit is $300,000 for both the master repurchase agreement and the mortgage loan participation purchase and sale agreement.
	On February 28, 2013, we entered into a master repurchase agreement with Bank of America, N.A. ("Bank of America"), which was amended in February 2014. Under the agreement with Bank of America, from time to time, we may transfer to Bank of America certain residential mortgage loans and/or other mortgage related assets and interests, against the transfer of funds by Bank of America, with a simultaneous agreement by Bank of America to sell to us those purchased assets at a specified date or on demand after the purchase date, against the transfer of funds by us. Under the master repurchase agreement, Bank of America will enter into transactions with us provided that the aggregate outstanding purchase price as of any date shall not exceed $100,000, and the aggregate outstanding purchase price for any type of transaction shall not exceed the applicable type sublimit.
	On June 24, 2013, we entered into a mortgage loan participation purchase and sale agreement with Bank of America, which was amended in February 2014. Under this agreement with Bank of America, from time to time, we may sell to Bank of America beneficial ownership interests in designated pools of qualifying, residential mortgage loans and the servicing rights relating thereto. The mortgage loan participation purchase and sale agreement will terminate in March 2014, unless terminated earlier under certain circumstances provided for therein. Under the mortgage loan participation purchase and sale agreement, Bank of America may enter into transactions with us to purchase participation certificates provided that the aggregate purchase price of such participation certificates as of any date shall not exceed $100,000.
	On November 19, 2012, we entered into a master loan participation and servicing agreement with Bank of Virginia, with a maximum borrowing capacity of $60,000. The master loan participation and servicing agreement provided that we could, from time to time, sell to Bank of Virginia beneficial ownership interests in qualifying, single-family mortgage loans. This agreement expired in November 2013.
	Through our December 2013 acquisition of Crossline, at December 31, 2013 we had warehouse lines of credit with Flagstar Bank and First Tennessee Bank with maximum borrowing capacities of $50,000 and $15,000, respectively, and expiration dates of July 2014 and August 2014, respectively. The Flagstar Bank and First Tennessee Bank warehouse lines of credit were terminated in February 2014 and January 2014, respectively, and the outstanding balances were repaid in full upon termination.
	Operating Lines of Credit
	The Company has a $7,200 operating line of credit agreement, which expires on June 30, 2014. Interest under the agreement is at the prime rate (with a floor of 4.00%) per annum. The line is collateralized by the net servicing fee cash flows from and proceeds on approved sales of mortgage servicing rights. The amount outstanding under the line amounted to $6,111 with an interest rate of 4.00% at December 31, 2013.
	The Company also has a $1,000 operating line of credit agreement, which expires on June 30, 2014. Interest under this agreement ranges between 5.25% and 6.00% per annum. The line is collateralized by the Company’s cost method investment in this lender and the net servicing fee cash flows from and proceeds on approved sales of mortgage servicing rights. The amount outstanding under the line amounted to $388 with an interest rate of 5.25% at December 31, 2013.
	The above mortgage funding and operating line 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 agreement. We were in compliance with all significant covenants at December 31, 2013.
	The Company intends to renew the mortgage funding arrangements and operating lines of credit when they mature and has no reason to believe the Company will be unable to do so.
	Term Loan
	On March 29, 2013, the Company entered into a Secured Term Promissory Note agreement (the "Note") with a stockholder to borrow $10,000. The Note was scheduled to mature on September 30, 2013 and bore interest at 5.00% (compounded monthly), through May 31, 2013, and thereafter at an interest rate of 12.50% (compounded monthly). The Note was repaid in full on May 15, 2013 with $4,345 of cash and 314,147 shares of the Company's common stock, at a per share price of $18.00, totaling $5,655 issued under the Company's private equity offering were sent directly to the stockholder for the remaining balance on the Note.
	As of and for the year ended December 31, 2013, the Company had no outstanding long-term borrowings.

	Losses on repurchases and indemnifications	(1,188		)	—		—
	Balance at end of period	$	3,709		$	1,917	$	—
	Because of the uncertainty in the various estimates underlying the mortgage repurchase and indemnifications liability, there is a range of losses in excess of the recorded reserve for mortgage repurchase and indemnifications that is reasonably possible. The estimate of the range of possible loss for representations and warranties does not represent a probable loss and is based on current available information, significant judgment and a number of assumptions that are subject to change. The high end of this range of reasonably possible losses in excess of the Company’s recorded reserve was approximately $1,720 at December 31, 2013, and was determined based upon modifying the assumptions (particularly to assume significant changes in investor repurchase demand practices) utilized in the Company’s best estimate of probable loss to reflect what it believes to be the high end of reasonably possible adverse assumptions.

	Through May 15, 2013, the Company had an agreement with a stockholder to pay an annual management fee of $320 for consulting and advisory services and strategic planning. The agreement was terminated on May 15, 2013 in conjunction with the Company’s private offering of common stock (see Note 17 “Capital Stock” for additional information related to the equity restructuring) and the Company agreed to pay the full annual management fee of $320. The Company also agreed to pay the stockholder an additional fee of $500 upon the earlier of the consummation of an initial public offering of its shares of common stock or May 15, 2014. The total management fees amounted to $820, $238 and $0, respectively, for the years ended December 31, 2013, 2012 and 2011, and are included in "General and administrative expense" on the Company's consolidated statements of income.
	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 FHA 203k loans and Fannie Mae Home Style renovation loans.

	Net deferred tax liabilities	$	28,379	$	14,381
	As of December 31, 2013, the Company had federal and state net operating loss carryforwards of $94,973 and $64,241, respectively, available to offset future taxable income and expiring from 2027 to 2033. As of December 31, 2012, the Company had federal and state net operating loss carryforwards of $15,230 and $11,444, respectively. The increase in both the federal and state net operating loss carryforwards during the year ended December 31, 2013 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, 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, 2013.

Commitments and Contingencies	12 Months Ended
	Dec. 31, 2013
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies
	Commitments to Extend Credit
	The Company enters into interest rate lock commitments ("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, 2013 and 2012 approximated $1,190,119 and $1,139,963, respectively.
	Leases
	The Company leases office space and equipment under non-cancelable operating agreements expiring through October 2022. Rent expense amounted to $3,458, $1,259 and $746 for the years ended December 31, 2013, 2012 and 2011, 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, 2013:
	2014	$	4,684
	2015	4,299
	2016	3,691
	2017	3,324
	2018	3,423
	Thereafter	6,364
	Total minimum rental payments	$	25,785
	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, 2013 and 2012. The Company’s required and actual net worth amounts are presented in the following table:
		December 31, 2013				December 31, 2012
		Net Worth 1		Net Worth Required		Net Worth 1		Net Worth Required
	HUD	$	298,429	$	2,500	$	51,437	$	1,000

	Various States	$	298,429	$0-$1,000		$	51,437	$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, 2013, 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.
	Other Contingencies
	During the year ended December 31, 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 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, 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 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. As a result, the Company has included certain specific reserves in its provision for reserve for mortgage repurchases and indemnifications during the year ended December 31, 2013 related to these purchased correspondent loans.

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. As part of the total issuance of shares in the initial public offering, the Company issued all 591,554 shares of treasury stock held, at a cost of $1,707, thereby reducing the balance of treasury stock to zero at December 31, 2013.
	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.
	Series A Convertible Preferred Stock (“Series A Preferred Shares”)
	During the year ended December 31, 2012, all 415,845 outstanding Series A Preferred Shares were redeemed and retired, at a per share redemption price of $3.61, for a total cash redemption payment of $1,500. In addition, at the time of the redemption, accrued and unpaid dividends of $43 were paid in cash to the sellers of the Series A Preferred Shares. As a result of this redemption, there were no outstanding Series A Preferred Shares as of December 31, 2012.
	Series D Convertible Preferred Stock (“Series D Preferred Shares”)
	During the year ended December 31, 2012, the Company issued 8,064,881 Series D Preferred Shares at per share price of $3.97, for total cash proceeds of $32,000. The Company incurred equity issuance costs totaling $1,826 related to the issuance of the Series D Preferred Shares.
	Series C Convertible Preferred Stock ("Series C Preferred Shares")
	During the year ended December 31, 2011, the Company issued $263,369 Series C Preferred Shares at a per share price of $3.61, for total cash proceeds of $950. The Company incurred equity issuance costs totaling $41 related to the issuance of the Series C Preferred Shares.
	Use of Capital and Common Stock Repurchases
	Prior to the conversion of the Company’s outstanding convertible preferred stock to common stock in May 2013, the Company paid cash dividends of $27, $119 and $257 to certain of its convertible preferred stockholders during the years ended December 31, 2013, 2012 and 2011, respectively. 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.
	The Company repurchased 630,699 shares of its common stock, at a per share price of $2.89, for a total cost of $1,820 during the year ended December 31, 2012, funding the repurchase from cash on hand. The shares were repurchased from a related party, who at the time of the repurchase was a member of the Company’s Board of Directors. Repurchases of common stock are accounted for using the cost method, with common stock in treasury classified in the balance sheet as a reduction of stockholders’ equity. 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, 2013 or 2011.

Stock-Based Compensation	12 Months Ended

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
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, 2013, there were a total of 369,616 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 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, 2013 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, 2012	101,494			$	3.97
	Granted	1,438,386			$	18
	Exercised	—			N/A
	Forfeited or expired	—			N/A
	Outstanding at December 31, 2013	1,539,880			$	17.08			9.3	$	1,275
	Exercisable at December 31, 2013	50,747			$	3.97			8.2	$	637
	During the year ended December 31, 2013, 33,831 stock options with a per-share exercise price of $3.97, an aggregate intrinsic value of $425 and remaining contractual term of 8.2 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, 2013 and 2012 (there we no options granted during the year ended December 31, 2011):
		Years ended December 31,
		2013				2012
	Fair value of underlying common stock	$	18			$	3.97
	Volatility	40		%		18		%
	Dividend yield	—		%		—		%
	Risk-free interest rate	1.08		%		1.01		%
	Expected term (years)	6.22				5.75
	The weighted average grant-date fair values per share of the stock options granted during the years ended December 31, 2013 and 2012 was $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 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, 2013 is as follows:
		Restricted Stock Units			Weighted Average Grant Date Fair Value Per Share
	Nonvested at December 31, 2012	—			N/A
	Granted	49,634			$	17.04
	Vested	—			N/A
	Forfeited	—			N/A
	Nonvested at December 31, 2013	49,634			$	17.04
	During the years ended December 31, 2013, 2012 and 2011, the Company recognized total stock-based compensation expense related to stock options and restricted stock units of $2,452, $13 and $0, respectively. During the years ended December 31, 2013, 2012 and 2011, the Company recognized related tax benefits of $987, $5 and $0, respectively. Total unrecognized stock-based compensation costs related to nonvested stock options and restricted stock units as of December 31, 2013 was $9,504 and $837, respectively, and will be recognized using the straight-line method over the weighted average remaining requisite service periods of three years and three 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.
	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
	The Company’s organizational structure is currently comprised of three operating segments: Originations, Servicing and Financing. 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, and reflect how the chief operating decision maker manages and evaluates the performance of the business, with a focus 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.

Subsequent Events	Subsequent Events
	On February 4, 2014, the Company completed its acquisition of Medallion Mortgage Company ("Medallion"), a residential mortgage originator based in southern California. Medallion originated more than $400,000 in mortgage loans during the year ended December 31, 2013 through its California and Utah locations, serving customers with an extensive portfolio of residential real estate loan programs. The acquisition of Medallion included 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 cash consideration for this acquisition was $258. Consideration yet to be paid for this acquisition also includes contingent consideration based upon future origination volume, for which the Company has not yet determined the acquisition date fair value. The contingent consideration is conditional upon Medallion achieving certain predetermined minimum mortgage loan origination goals during the two-year period following the acquisition date and is uncapped in amount. Total consideration for Medallion, which, along with working capital for the business, will be funded out of the Company's existing cash resources.

Basis_of_Presentation_and_Sign1

Basis of Presentation and Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
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.
Risks 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. The Company is subject to interest rate risk to the extent that in a rising interest rate environment, the Company may experience a decrease in loan production, as well as decreases in the value of mortgage loans held for sale and in commitments to originate loans, which may negatively impact the Company’s operations. Conversely, in a decreasing interest rate environment, the value of the Company’s MSRs may decrease, which could negatively impact the Company’s operations. 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 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 transfers 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 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: 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 gain 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.
	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 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 MSR 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 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.
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.
	To the extent derivatives subject to master netting arrangements meet applicable requirements, the Company presents the derivative balances and related cash collateral amounts net on the balance sheet.
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 three to ten years for furniture and equipment and three years for computer software. Leasehold improvements are amortized using the straight-line method over the shorter of the related lease term or their estimated economic useful lives.
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 a 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 a straight line amortization method. 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 asset is 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 an impairment charge would be recorded to earnings.
	Indefinite-lived purchased intangible assets consist of trade names. 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. 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 that goodwill or other indefinite-lived intangible assets are impaired. If the Company determines that it is more likely than not that goodwill or other intangible assets are impaired, a quantitative impairment test is performed. For the quantitative impairment test, the Company estimates and compares the fair value of the goodwill or indefinite-lived intangible asset with its carrying amount. If the carrying amount of the goodwill or other 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.
Long-Lived Assets	Long-Lived Assets: The Company periodically assesses long-lived assets, including property and equipment and definite-lived intangible assets, 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.
Investment in Closely Held Entity	Investment in Closely Held Entity: Investment in closely held entity consists of shares of voting common and preferred stock, which the Company owns in a non-publicly traded entity. The investment is carried at cost as the Company does not exercise significant influence over the entity’s operating and financial activities.
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. Advertising and marketing is expensed as incurred
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. 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.
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 $43,104 and $15,056 at December 31, 2013 and 2012, 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.
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 (beginning January 1, 2013), derivatives and loans held for sale, or on a nonrecurring basis, such as when measuring MSRs upon initial recognition and measuring impairments on MSRs (for periods prior to January 1, 2013), 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 quoted market or contracted prices or market price equivalents.
	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 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.
