Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and basis of presentation	1. Organization and basis of presentation
	Altisource Residential Corporation is a Maryland REIT focused on acquiring, owning and managing single-family rental properties throughout the United States. We acquire our rental properties primarily through the acquisition of sub-performing and non-performing mortgage loan portfolios, which is a differentiated approach that we believe strategically positions us to take advantage of market opportunities better than market participants that are solely focused on real estate-owned (“REO”) acquisitions. We conduct substantially all of our activities through our wholly owned subsidiary Altisource Residential, L.P.
	On December 21, 2012 we became a stand-alone publicly traded company with an initial capital contribution of $100 million. We have a long-term service agreement with Altisource, a leading provider of real estate and mortgage portfolio management, asset recovery and customer relationship management services. We also have servicing agreements with three separate servicers.
	We are managed by Altisource Asset Management Corporation ("AAMC"). We rely on AAMC for administering our business and performing certain of our corporate governance functions. AAMC also provides portfolio management services in connection with our acquisition and management of sub-performing and non-performing loans and REO properties. AAMC was formed on March 15, 2012 as a wholly owned subsidiary of Altisource and was spun off from Altisource into a stand-alone publicly traded company concurrently with our separation from Altisource.
	Since we commenced operations, we have completed three public equity offerings with aggregate net proceeds of approximately $1.1 billion. On March 22, 2013, September 12, 2013 and September 23, 2013, we entered into three separate repurchase agreements to finance the acquisition and ownership of residential mortgage loans and REO properties. The maximum aggregate funding available under these repurchase agreements initially was $425.0 million. We subsequently increased the aggregate funding capacity under each repurchase agreement as follows:
	•	Credit Suisse (“CS”) is the lender on the repurchase agreement entered into on March 22, 2013, (the “CS repurchase agreement”). The CS Repurchase Agreement was amended on April 21, 2014 to initially increase the aggregate maximum borrowing capacity from $100.0 million to $200.0 million. The maturity date of the CS repurchase agreement was also extended to April 20, 2015, subject to an additional one-year extension with the approval of the lender. On June 11, 2014, we further amended the CS repurchase agreement to increase the aggregate maximum borrowing capacity from $200.0 million to $375.0 million, subject to certain sublimits, for the period from June 11, 2014 through October 11, 2014. In October 2014, we further extended the temporary increase with CS in order to enable us to complete a securitization of the non-performing mortgage loans comprising the increased capacity. . Following the securitization of these loans, on December 23, 2014, we further amended the CS repurchase agreement and entered into a securities repurchase agreement with Credit Suisse to obtain additional financing on the bonds issued by us in our securitizations. This December 2014 amendment increased our aggregate maximum borrowing capacity under the CS repurchase agreement to $225.0 million. We are in discussions with CS to renew the repurchase agreement. No assurance can be provided that we will be able to renew this facility on reasonable terms, on a timely basis or at all.
	•	Deutsche Bank (“DB”) is the lender on the repurchase agreement dated September 12, 2013 (the “DB repurchase agreement”). The DB repurchase agreement was amended on December 18, 2013, has an aggregate funding capacity of $250.0 million and matures on March 11, 2016. The DB repurchase agreement includes a provision that, beginning in the nineteenth month, we will not be able to finance mortgage loans in excess of amounts outstanding under the facility at the end of the eighteenth month.
	•	Wells Fargo (“Wells”) is the lender under the repurchase agreement dated September 23, 2013 (the “Wells repurchase agreement”). The Wells repurchase agreement was amended it on December 23, 2013 to initially increase the aggregate maximum borrowing capacity from $200.0 million to $400.0 million. On June 25, 2014, we further amended the Wells repurchase agreement to increase the aggregate maximum borrowing capacity from $400.0 million to $1.0 billion, subject to certain sublimits. On December 31, 2014, we further amended the Wells repurchase agreement to reduce the aggregate maximum borrowing capacity from $1.0 billion to $750.0 million to reflect the securitization of a significant portion of our non-performing loans that previously had been financed under the Wells repurchase agreement. The maturity date of the Wells repurchase agreement was March 23, 2015. However, on February 20, 2015, we exercised our option to extend the termination date of this facility to March 23, 2016. We are in discussions with Wells to further extend the repurchase agreement with an ability to obtain additional funding. No assurance can be provided that we will be able to renew this facility on reasonable terms, on a timely basis or at all. In the event we cannot renew the agreement, the advance rate will be reduced by 10% after the first 90 days of the extension term and we will not be entitled to draw additional funds under the facility.
	Following all of the amendments described above, the maximum aggregate funding available to us under these repurchase agreements as of December 31, 2014 was $1.2 billion, subject to certain sublimits, eligibility requirements and conditions precedent to each funding. As of December 31, 2014, an aggregate of $1.0 billion was outstanding under our repurchase agreements. All obligations under each of these repurchase agreements are fully guaranteed by us.
	On November 25, 2014, we completed a securitization transaction in which ARLP Securitization Trust, Series 2014-2 ("ARLP 2014-2") issued $270.8 million in Class A Notes (the “Class A Notes”) with a weighted yield of approximately 3.85% and $234.0 million in Class M Notes (the “Class M Notes”). No interest will be paid on any Class M Notes while any Class A Notes remain outstanding. We retained $95.8 million of the Class A Notes and all of the Class M Notes in our taxable REIT subsidiary (“TRS”). The Class A Notes and Class M Notes are secured solely by the non-performing mortgage loans and REO properties of ARLP 2014-2 and not by any of our other assets. The assets of ARLP 2014-2 are the only source of repayment and interest on the Class A Notes and the Class M Notes. The Class A Notes and the Class M Notes mature on January 26, 2054, and we do not guaranty any of the obligations of ARLP 2014-2 under the terms of the Indenture governing the notes or otherwise. As of December 31, 2014, the book value of the underlying securitized assets held by ARLP 2014-2 was $333.0 million.
	On September 25, 2014, we completed a securitization transaction in which ARLP Securitization Trust, Series 2014-1 (“ARLP 2014-1”) issued $150.0 million in Class A Notes (the “Class A Notes”) with a weighted yield of approximately 3.47% and $32.0 million in Class M Notes (the “Class M Notes”) with a weighted yield of 4.25%. The Class A Notes and the Class M Notes are secured solely by the non-performing mortgage loans and REO properties of ARLP 2014-1 and not by any of our other assets. The assets of ARLP 2014-1 are the only source of repayment and interest on the Class A Notes and the Class M Notes. The Class A Notes and the Class M Notes mature on September 25, 2044, and we do not guaranty any of the obligations of ARLP 2014-1 under the terms of the Indenture governing the notes or otherwise. As of December 31, 2014, the book value of the underlying securitized assets held by ARLP 2014-1 was $212.7 million.
	We retained all of the Class M Notes issued by ARLP 2014-1 in our TRS. On September 30, 2014, pursuant to a master repurchase agreement, the TRS sold $15.0 million of the Class M Notes to NewSource Reinsurance Company Ltd, ("NewSource"), an entity in which we own 100% of the outstanding preferred stock and in which AAMC owns 100% of the outstanding common stock, for a purchase price of $15.0 million. The master repurchase agreement required the TRS to repurchase the Class M Notes from NewSource at a 5.0% yield on December 28, 2014, subject to the parties’ option to extend the master repurchase agreement for an additional 89 day period. On December 26, 2014, the parties agreed to extend the agreement to March 27, 2015. In no event can the master repurchase agreement be extended beyond September 29, 2015.
	We ceased to be a development stage enterprise in the second quarter of 2013.
	Basis of presentation and use of estimates
	The accompanying audited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States which we refer to as "U.S. GAAP." All wholly owned subsidiaries are included and all intercompany accounts and transactions have been eliminated. The preparation of consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ materially from those estimates.
	Recently issued accounting standards
	In January 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-04, Troubled Debt Restructurings by Creditors. It provides that a repossession or foreclosure has occurred, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendment requires disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in mortgage loans collateralized by residential real estate property that are in the process of foreclosure. The amended guidance may be applied using either a prospective transition method or a modified retrospective transition method and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2014, with early adoption permitted. We do not expect this amendment to have a significant effect on our financial position or results of operations.
	In May 2014, the FASB issued ASU 2014-09 Revenue from Contracts with Customers. ASU 2014-09 is a comprehensive new revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. ASU 2014-09 may be applied using either a full retrospective or a modified retrospective approach and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and early adoption is not permitted. We do not expect this amendment to have a significant effect on our financial position or results of operations.

Accounting Policies [Abstract]
Summary of significant accounting policies	2. Summary of significant accounting policies
	Cash equivalents
	We consider highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.
	Comprehensive income
	Because comprehensive income (loss) equals net income (loss), separate statements of comprehensive income (loss) are not presented as part of our consolidated financial statements.
	Concentration of credit risk
	We maintain our cash and cash equivalents at banking institutions. Certain account balances exceed FDIC insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage.
	Earnings per share
	Basic earnings per share is computed by dividing net income (loss) by the weighted average common stock outstanding during the period. Diluted earnings per share is computed by dividing net income (loss) by the weighted average common stock outstanding for the period plus the dilutive effect of stock options and restricted stock outstanding using the treasury stock method and if converted method, respectively.
	Expense reimbursement and incentive management fee
	Our asset manager's primary business is asset management. In its role as our asset manager, AAMC incurs indirect costs (e.g. payroll and overhead) related to managing our business which are contractually reimbursable by us. AAMC allocates indirect costs to us as incurred by estimating the percentage of time spent for our benefit.
	The incentive management fee we pay to our Manager is based on the quarterly cash available for distribution to our stockholders. Pursuant to our asset management agreement, our Manager's incentive management fee structure entitles it to receive a share of our cash flow available for distribution to our stockholders. If we do not generate taxable income that is distributable to our stockholders, then we will not be required to pay incentive management fees.
	Fair value of financial instruments
	We designate fair value measurements into three levels based on the lowest level of substantive input used to make the fair value measurement. Those levels are as follows:
	•	Level 1 - Quoted prices in active markets for identical assets or liabilities.
	•	Level 2 - Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities.
	•	Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	Income taxes
	We believe that we have complied and will continue to comply with the provisions of the federal income tax code applicable to REITs beginning for the year ended December 31, 2013 and elected REIT status upon filing of our 2013 income tax return. Accordingly, we believe that we will not be subject to federal income tax beginning in the year ended December 31, 2013 and going forward on the portion of our REIT taxable income that is distributed to our shareholders as long as certain asset, income and share ownership tests are met. If after electing to be taxed as a REIT, we subsequently fail to qualify as a REIT in any taxable year, we generally will not be permitted to qualify for treatment as a REIT for federal income tax purposes for the four taxable years following the year during which qualification is lost.
	Our TRSs will be subject to federal and state income taxes. Income taxes are provided for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted rates expected to apply to taxable income in the years in which management expects those temporary differences to be recovered or settled. The effect on deferred taxes of a change in tax rates is recognized in income in the period in which the change occurs. Subject to our judgment, we reduce a deferred tax asset by a valuation allowance if it is “more likely than not” that some or all of the deferred tax asset will not be realized. Tax laws are complex and subject to different interpretations by the taxpayer and respective governmental taxing authorities. Significant judgment is required in evaluating tax positions, and we recognize tax benefits only if it is more likely than not that a tax position will be sustained upon examination by the appropriate taxing authority.
	Mortgage loans
	Upon the acquisition of mortgage loans, we record the assets at fair value which is the purchase price we paid for the loans on the acquisition date. Mortgage loans are subsequently accounted for at fair value under the fair value option election with unrealized gains and losses recorded in current period earnings. We have concluded that mortgage loans accounted for at fair value timely reflect the results of our investment performance.
	We determine the purchase price for mortgage loans at the time of acquisition by using a discounted cash flow valuation model and considering alternate loan resolution probabilities including modification, liquidation or conversion to rental property. Observable inputs to the model include current interest rates, loan amounts, status of payments and property types. Unobservable inputs to the model include discount rates, forecast of future home prices, alternate loan resolution probabilities, resolution timelines and the value of underlying properties.
	After mortgage loans are acquired, the fair value of each loan is adjusted in each subsequent reporting period as the loan proceeds to a particular resolution (i.e., modification, or conversion to real estate owned). As a loan approaches resolution, the resolution timeline for that loan decreases and costs embedded in the discounted cash flow model for loan servicing, foreclosure costs and property insurance are incurred and removed from future expenses. The shorter resolution timelines and reduced future expenses each increase the fair value of the loan. The increase in the value of the loan is recognized in net unrealized gain on mortgage loans in our consolidated statements of operations.
	We also recognize unrealized gains and losses in the fair value of the loans in each reporting period when our mortgage loans are transferred to real estate owned. The transfer to real estate owned occurs when we have obtained title to the property through completion of the foreclosure process. The fair value of these assets at the time of transfer to real estate owned is estimated using BPOs.
	AAMC’s capital markets group determines the fair value of mortgage loans monthly and has developed procedures and controls governing the valuation process relating to these assets. The capital markets group reports to our Investment Committee, a committee of our Chief Executive Officer and our Chairman that oversees and approves the valuations. The capital markets group also monitors the valuation model for performance against actual results which is reported to the Investment Committee and used to continuously improve the model.
	Loans held for sale
	Loans held for sale, which consist of re-performing residential mortgage loans acquired from others, are recorded at the lower of cost or fair value. We do not originate loans. During 2014, management decided to sell certain re-performing loans and as such they were reclassified as loans held for sale from loans held for investment.
	Real estate impairment
	With respect to residential rental properties classified as held for use, we perform an impairment analysis using estimated cash flows if events or changes in circumstances indicate that the carrying value may be impaired, such as prolonged vacancy, identification of materially adverse legal or environmental factors, changes in expected ownership period or a decline in market value to an amount less than cost. This analysis is performed at the property level. These cash flows are estimated based on a number of assumptions that are subject to economic and market uncertainties including, among others, demand for rental properties, competition for customers, changes in market rental rates, costs to operate each property and expected ownership periods.
	If the carrying amount of a held for use asset exceeds the sum of its undiscounted future operating and residual cash flows, an impairment loss is recorded for the difference between estimated fair value of the asset and the carrying amount. We generally estimate the fair value of assets held for use by using BPOs. In some instances, appraisal information may be available and is used in addition to BPOs.
	Residential properties
	Upon the acquisition of real estate, generally through the completion of foreclosure, we record the residential property at fair value as of the acquisition date as a component of real estate owned based on information obtained from a broker's price opinion, a full appraisal or the price given in a current contract of sale of the property. After a short evaluation period, we perform property renovations to maximize the value of the property for our rental strategy. Such expenditures are part of our initial investment in a property and, therefore, are classified as investing activities in our consolidated statement of cash flows. Subsequently, the residential property, including any renovations that improve or extend the life of the asset, are accounted for at cost. The cost basis is depreciated using the straight-line method over an estimated useful life of three to 27.5 years based on the nature of the components. Interest and other carrying costs incurred during the renovation period are capitalized until the property is ready for its intended use. Expenditures for ordinary maintenance and repairs are charged to expense as incurred.
	Expenditures directly related to successful leasing efforts such as lease commissions are included in deferred leasing and financing costs, net and are stated at amortized cost. Such expenditures are part of our operations and, therefore, are classified as operating activities in our consolidated statement of cash flows. Capitalized leasing costs are amortized on a straight-line basis over the lease term of the respective leases which generally are from one to 2 years.
	Residential properties are classified either as held for use or held for sale. Residential properties are classified as real estate and related assets held for sale when sale of the assets has been formally approved and is expected to occur in the next twelve months. We record residential properties held for sale at the lower of the carrying amount or estimated fair value less costs to sell. The impairment loss is the amount by which the carrying amount exceeds the estimated fair value less costs to sell.
	Residential rental revenues
	Minimum contractual rents from leases are recognized on a straight-line basis over the terms of the leases in residential rental revenues. Therefore, actual amounts billed in accordance with the lease during any given period may be higher or lower than the amount of rental revenue recognized for the period. Straight-line rental revenue commences when the customer takes control of the leased premises. Deferred rents receivable, net represents the amount by which straight-line rental revenue exceeds rents currently billed in accordance with lease agreements. Contingent rental revenue is accrued when the contingency is removed. Termination fee income is recognized when the customer has vacated the rental property, the amount of the fee is determinable and collectability is reasonably assured.
	Rents receivable, net and deferred rents receivable, net are reduced by an allowance for amounts that become uncollectible. We regularly evaluate the adequacy of our allowance for doubtful accounts. The evaluation takes into consideration the aging of accounts receivable and our analysis of customer personal profile and review past due account balances. Rents receivable, net and deferred rents receivable, net are written-off when we have deemed that the amounts are uncollectible.
	Restricted cash
	Restricted cash represents cash deposits that are legally restricted or held by third parties on our behalf, such as escrows and reserves for debt service established pursuant to certain of our repurchase agreements.
	Unconsolidated affiliates
	We account for our investment in NewSource using the cost method because we do not exercise significant influence over NewSource. As a result, we recognize preferred dividend income from this investment when received.

Mortgage Loans on Real Estate [Abstract]
Mortgage loans	3. Mortgage loans
	During the year ended December 31, 2014, Residential acquired an aggregate of 8,441 mortgage loans and REO properties, consisting of the following:
	Acquisitions of non-performing residential mortgage loans
	During the year ended December 31, 2014, we acquired an aggregate of 7,326 residential mortgage loans, substantially all of which were non-performing, and 237 REO properties having an aggregate UPB of approximately $1.9 billion and an aggregate market value of underlying properties of $1.8 billion. The aggregate purchase price for these acquisitions was $1.2 billion.
	Acquisition of re-performing residential mortgage loans
	On June 27, 2014, we acquired 879 re-performing mortgage loans with an aggregate market value of underlying properties of $271.1 million for an aggregate purchase price of $144.6 million. Under ASC 310-30, acquired loans may be aggregated and accounted for as a pool of loans if the loans being aggregated have common risk characteristics. A pool is accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows. These 879 re-performing residential mortgage loans were determined to have common risk characteristics and have been accounted for as a single loan pool. Under ASC 310-30, we estimate cash flows expected to be collected, adjusted for expected prepayments and defaults expected to be incurred over the life of the loan pool. We determine the excess of the loan pool's contractually required principal and interest payments over the expected cash flows as an amount that should not be accreted, the nonaccretable yield. The difference between expected cash flows and the present value of the expected cash flows is referred to as the accretable yield, which represents the amount that is expected to be recorded as interest income over the remaining life of the loan pool. For the year ended December 31, 2014, we recognized no provision for loan loss and no adjustments to the amount of the accretable yield. For the year ended December 31, 2014, we accreted $2.6 million into interest income with respect to our re-performing loans. As of December 31, 2014, these re-performing loans, having a UPB of $18.4 million and a carrying value of $12.5 million, were held for sale. During October 2014, we sold an aggregate of 934 re-performing loans to an unrelated third party for an aggregate purchase price of $164 million.
	The following tables present information regarding the estimates of the contractually required payments and the cash flows expected to be collected as of the date of the acquisition and changes in the balance of the accretable yield ($ in thousands):

	-5	Includes 46 REOs.
	-6	This acquisition consisted of a portfolio of re-performing loans.
	During the year ended December 31, 2014, we recognized $3.1 million for due diligence costs related to these and other transactions in both general and administrative expense and related party general and administrative expense. During the year ended December 31, 2013, we expensed $3.5 million for due diligence costs.
	Generally, we expect that our residential mortgage loan portfolio may grow at an uneven pace, as opportunities to acquire distressed residential mortgage loans may be irregularly timed and may involve large portfolios of loans, and the timing and extent of our success in acquiring such loans cannot be predicted. In addition, for any given portfolio of loans that we agree to acquire, we typically acquire fewer loans than originally expected, as certain loans may be resolved prior to the closing date or may fail to meet our diligence standards. The number of unacquired loans typically constitutes a relatively small portion of a particular portfolio. In some cases, the number of loans we do not acquire could be significant. In any case where we do not acquire the full portfolio, appropriate adjustments are made to the applicable purchase price.
	Throughout this report, all unpaid principal balance and market value amounts for the portfolios we have acquired are provided as of “cut-off date” for each transaction unless otherwise indicated. The “cut-off date” for each acquisition is a date shortly before the closing used to identify the final loans being purchased and the related unpaid principal balance, market value of underlying properties and other characteristics of the loans.
	Transfer of mortgage loans to real estate owned
	During the year ended December 31, 2014 and 2013, we transferred an aggregate of 3,682 and 226 mortgage loans, respectively, to REO at an aggregate fair value based on broker price opinions ("BPOs"), of $587.3 million and $31.0 million, respectively. Such transfers occur when the foreclosure sale is complete. In connection with these transfers to REO, we recorded $124.9 million and $8.3 million, respectively, in net unrealized gains on mortgage loans.
	Dispositions
	During the year ended December 31, 2014 and 2013, we disposed of 735 and 211 mortgage loans, respectively, primarily through short sales, refinancing and foreclosure sales. In connection with these dispositions, we recorded $55.8 million and $10.5 million, respectively, of net realized gains on mortgage loans. During October 2014, we sold 934 re-performing loans to an unrelated third party and recognized a gain of $2.8 million. The sale included 770 loans from the re-performing mortgage loans held for sale, purchased in the second quarter of 2014, and 164 loans that have transitioned to re-performing status from prior non-performing loan acquisitions that have a clean pay history of at least six months.

	Acquisitions
	During the year ended December 31, 2014, we acquired 237 REO properties as part of our portfolio acquisitions. During the year ended December 31, 2013, we acquired 40 REO properties. The aggregate purchase price attributable to these acquired REO properties was $34.1 million for the year ended December 31, 2014 and was $6.2 million for the year ended December 31, 2013.
	Real estate held for use
	As of December 31, 2014, we had 3,349 REO properties held for use. Of these properties, 336 had been rented, 197 were being listed for rent and 254 were in varying stages of renovation. We generally rent our REO properties under non-cancelable leases with a term of one year. Future minimum rental revenues under leases existing for the 336 properties that were rented as of December 31, 2014 are approximately $3.6 million for 2015 and approximately $0.6 million for 2016. With respect to the remaining 2,562 REO properties, we will make a final determination whether each property meets our rental profile after (a) applicable state redemption periods have expired, (b) the foreclosure sale has been ratified, (c) we have recorded the deed for the property, (d) utilities have been activated and (e) we have secured access for interior inspection. A majority of the REO properties are subject to state regulations which require us to await the expiration of a redemption period before a foreclosure can be finalized. We include these redemption periods in our portfolio pricing which generally reduces the price we pay for the mortgage loans. Once the redemption period expires, we immediately proceed to record the new deed, take possession of the property, activate utilities, and start the inspection process in order to make our final determination. As of December 31, 2013, we had 246 REO properties held for use. Of these properties, 14 had been rented, 11 were being listed for rent and 18 were in various stages of renovation. With respect to the remaining 203 REO properties, we were in the process of determining whether these properties would meet our rental profile. If a REO property meets our rental profile, we determine the extent of renovations that are needed to generate an optimal rent and maintain consistency of renovation specifications for future branding. If we determine that the REO property will not meet our rental profile, we list the property for sale, in certain instances after renovations are made to optimize the sale proceeds.
	Real estate held for sale
	As of December 31, 2014, we classified 611 REO properties having an aggregate carrying value of $92.2 million as real estate held for sale as they do not meet our residential rental property investment criteria. As of December 31, 2013, we had 16 REO properties having an aggregate carrying value of $1.2 million held for sale. None of these REO properties have any operations; therefore, we are not presenting discontinued operations related to these properties.
	Dispositions
	During the year ended December 31, 2014, we disposed of 221 residential properties and recorded $9.5 million of net realized gains on real estate. We disposed of four residential properties during the year ended December 31, 2013. There were no significant gains or losses on the dispositions in 2013.

	On October 17, 2013, we invested $18.0 million in the non-voting preferred stock of NewSource, a title insurance and reinsurance company in Bermuda. We are eligible to receive a 12% annual non-cumulative preferred dividend on our investment. We account for our investment in NewSource using the cost method because we do not exercise significant influence over NewSource. As a result, we recognize preferred dividend income from this investment when received. We received preferred dividends of $2.2 million in 2014.

	The carrying values of our cash and cash equivalents, restricted cash, related party receivables, accounts payable and accrued liabilities, related party payables and investment in NewSource are equal to or approximate fair value. The fair value of mortgage loans is estimated using our asset manager's proprietary pricing model. The fair value of transfers of mortgage loans to real estate owned is estimated using BPOs. The fair value of re-performing mortgage loans held for sale is estimated using the present value of the future estimated principal and interest payments of the loan, with the discount rate used in the present value calculation representing the estimated effective yield of the loan. The fair value of the repurchase agreements is estimated using the income approach based on credit spreads available to us currently in the market for similar floating rate debt. The fair value of other secured borrowings is estimated using observable market data.

The significant unobservable inputs used in the fair value measurement of our mortgage loans are discount rates, forecasts of future home prices, alternate loan resolution probabilities, resolution timelines and the value of underlying properties. Significant changes in any of these inputs in isolation could result in a significant change to the fair value measurement. A decline in the discount rate in isolation would increase the fair value. A decrease in the housing pricing index in isolation would decrease the fair value. Individual loan characteristics such as location and value of underlying collateral affect the loan resolution probabilities and timelines. An increase in the loan resolution timeline in isolation would decrease the fair value. A decrease in the value of underlying properties in isolation would decrease the fair value. The following table sets forth quantitative information about the significant unobservable inputs used to measure the fair value of our mortgage loans as of December 31, 2014 and December 31, 2013:

	Repurchase Agreements
	Our operating partnership and certain of its Delaware Statutory Trust subsidiaries, as applicable, have entered into master repurchase agreements with major financial institutions. The purpose of these repurchase agreements is to finance the acquisition and ownership of mortgage loans and REO properties in our portfolio. We have effective control of the assets associated with these agreements and therefore have concluded these are financing arrangements. As of December 31, 2014, the weighted average annualized interest rate on borrowings under our repurchase agreements was 3.05%, excluding amortization of deferred financing costs.

	Under the terms of each repurchase agreement, as collateral for the funds drawn thereunder, subject to certain conditions, our operating partnership will sell to the applicable lender equity interests in the Delaware statutory trust subsidiary that owns the applicable underlying mortgage assets on our behalf, or the trust will directly sell such underlying mortgage assets. In the event the lender determines the value of the collateral has decreased, the lender has the right to initiate a margin call and require us, or the applicable trust subsidiary, to post additional collateral or to repay a portion of the outstanding borrowings. The price paid by the lender for each mortgage asset we finance under the repurchase agreements is based on a percentage of the market value of the mortgage asset and may depend on its delinquency status. With respect to funds drawn under the repurchase agreements, our applicable subsidiary is required to pay the lender interest based on LIBOR or at the lender’s cost of funds plus a spread calculated based on the type of applicable mortgage assets collateralizing the funding, as well as certain other customary fees, administrative costs and expenses to maintain and administer the repurchase agreements. We do not collateralize any of our repurchase facilities with cash.
	The repurchase agreements require us to maintain various financial and other covenants, including maintaining a minimum adjusted tangible net worth, a maximum ratio of indebtedness to adjusted tangible net worth and specified levels of unrestricted cash. In addition, the repurchase agreements contain customary events of default. We are restricted by the terms of our repurchase agreements from paying dividends greater than our REIT taxable income in a calendar year.
	We are currently in compliance with the covenants and other requirements with respect to the repurchase agreements. We monitor our banking partners’ ability to perform under the repurchase agreements and have concluded there is currently no reason to doubt that they will continue to perform under the repurchase agreements as contractually obligated. For additional information on the repurchase agreements, please see Note 1, "Organization and basis of presentation."
	Other Secured Debt
	On November 25, 2014, we completed a securitization transaction in which ARLP 2014-2 issued $270.8 million in Class A Notes with a weighted yield of approximately 3.85% and $234.0 million in Class M Notes. No interest will be paid on any Class M Notes while any Class A Notes remain outstanding. We retained $95.8 million of the Class A Notes and all of the Class M Notes in our TRS. The Class A Notes and Class M Notes are secured solely by the non-performing mortgage loans and REO properties of ARLP 2014-2 and not by any of our other assets. The assets of ARLP 2014-2 are the only source of repayment and interest on the Class A Notes and the Class M Notes. The Class A Notes and the Class M Notes mature on January 26, 2054, and we do not guaranty any of the obligations of ARLP 2014-2 under the terms of the Indenture governing the notes or otherwise. As of December 31, 2014, the book value of the underlying securitized assets held by ARLP 2014-2 was $333.0 million.
	On September 25, 2014, we completed a securitization transaction in which ARLP 2014-1 issued $150.0 million in Class A Notes with a weighted yield of approximately 3.47% and $32.0 million in Class M Notes with a weighted yield of 4.25%. The Class A Notes and Class M Notes are secured solely by the non-performing mortgage loans and REO properties of ARLP 2014-1 and not by any of our other assets. The assets of ARLP 2014-1 are the only source of repayment and interest on the Class A Notes and the Class M Notes. The Class A Notes and the Class M Notes mature on September 25, 2044, and we do not guaranty any of the obligations of ARLP 2014-1 under the terms of the Indenture governing the notes or otherwise. As of December 31, 2014, the book value of the underlying securitized assets held by ARLP 2014-1 was $212.7 million.
	We retained all of the Class M Notes issued by ARLP 2014-1 in our TRS. On September 30, 2014, pursuant to a master repurchase agreement, the TRS sold $15.0 million of the Class M Notes to NewSource for a purchase price of $15.0 million. The master repurchase agreement required the TRS to repurchase the Class M Notes from NewSource at a 5.0% yield on December 28, 2014, with the parties having the option to extend the master repurchase agreement for an additional 89 day period. On December 26, 2014, the parties agreed to extend the agreement to March 27, 2015. In no event can the master repurchase agreement be extended beyond September 29, 2015.

	Litigation, claims and assessments
	From time to time, we may be involved in various claims and legal actions arising in the ordinary course of business. As of December 31, 2014, we were not a party to, and our properties were not subject to, any pending or threatened legal proceedings that individually or in the aggregate, are expected to have a material impact on our financial condition, results of operations or cash flows. Subsequent to December 31, 2014, the following legal proceedings were commenced with respect to us:
	On January 15, 2015, a shareholder derivative action was filed in the Circuit Court of Maryland for Baltimore City by a purported shareholder under the caption The Police Retirement System of Saint Louis v. Erbey, et al., 24-C-15-000223.  The action names as defendants William C. Erbey and each of the members of our Board of Directors and alleges that Mr. Erbey and our directors breached fiduciary duties in connection with the asset management agreement among us, Altisource Residential, L.P. and AAMC.  The action also names Altisource Residential, L.P. and AAMC as defendants and alleges that AAMC aided and abetted the purported breaches of fiduciary duty and has been unjustly enriched by the asset management agreement.  The complaint also names us as a nominal defendant.  The plaintiff seeks, among other things, an order declaring that Mr. Erbey and the director defendants have breached their fiduciary duties, an order declaring that Mr. Erbey and AAMC have been unjustly enriched, an order declaring that the asset management agreement is unenforceable and directing our Board of Directors to terminate the asset management agreement, damages, disgorgement by Mr. Erbey and AAMC of allegedly wrongful profits, changes to our corporate governance and an award of attorney’s and other fees and expenses.  We believe the complaint is without merit. At this time, we are not able to predict the ultimate outcome of this matter, nor can we estimate the range of possible loss, if any.
	On December 24, 2014, a shareholder derivative action was filed in the United States District Court for the Southern District of Florida by a purported shareholder of Ocwen under the caption Sokolowski v. Erbey, et al., 14-cv-8160-1. The action named the directors of Ocwen as defendants and alleged, among other things, various breaches of fiduciary duties by the directors of Ocwen. On February 11, 2015, plaintiff filed an amended complaint naming the directors of Ocwen as defendants and also naming Altisource, Home Loan Servicing Solutions, AAMC and us as alleged aiders and abettors of the purported breaches of fiduciary duties. The amended complaint alleges that the directors of Ocwen breached their fiduciary duties by, among other things, allegedly failing to exercise oversight over Ocwen's compliance with applicable laws, rules and regulations; failing to exercise oversight responsibilities with respect to the accounting and financial reporting processes of Ocwen; failing to prevent conflicts of interest and allegedly improper related party transactions; failing to adhere to Ocwen's code of conduct and corporate governance guidelines; selling personal holdings of Ocwen stock on the basis of material adverse inside information; and disseminating allegedly false and misleading statements regarding Ocwen's compliance with regulatory obligations and allegedly self-dealing transactions with related companies. Plaintiff claims that as a result of the alleged breaches of fiduciary duties, Ocwen has suffered damages including settlements with regulatory agencies in excess of $2 billion, injury to its reputation and corporate goodwill, and exposure to governmental investigations and securities and consumer class action lawsuits. In addition to the derivative claims, the plaintiff also alleges an individual claim that Ocwen's 2014 proxy statement allegedly contained untrue statements of material fact and failed to disclose material information in violation of federal securities laws. The plaintiff seeks, among other things, an order requiring the defendants to repay to Ocwen unspecified amounts by which Ocwen has been damaged or will be damaged, an award of an unspecified amount of exemplary damages, changes to Ocwen's corporate governance, and an award of attorney's and other fees and expenses. We believe the claims against us in the matter are without merit. At this time, we are not able to predict the ultimate outcome of this matter, nor can we estimate the range of possible loss, if any.
	Management does not believe that we have incurred an estimable, probable or material loss by reason of any of the above actions.

	Asset Management Agreement with AAMC
	Upon completion of our separation and AAMC’s separation from Altisource on December 21, 2012, we entered into a 15-year asset management agreement with AAMC. Pursuant to the asset management agreement, AAMC designs and implements our business strategy, administers our business activities and day-to-day operations and provides corporate governance services, subject to oversight by our Board of Directors. AAMC is responsible for, among other duties: (1) performing and administering all of our day-to-day operations, (2) determining investment criteria through our Investment Policy in cooperation with our Board of Directors, (3) sourcing, analyzing and executing asset acquisitions, including our acquisition of sub-performing and non-performing residential mortgage loan portfolios and related financing activities, (4) analyzing and performing sales of properties, (5) overseeing Altisource’s renovation, leasing and property management of our single-family rentals, (6) overseeing Ocwen’s servicing of our residential mortgage loan portfolios, (7) performing asset management duties and (8) performing corporate governance and other management functions, including financial, accounting and tax management services.
	AAMC provides us with a management team and appropriate support personnel who have substantial sub-performing and non-performing loan portfolio experience. AAMC’s management also has significant corporate governance experience that enables us to manage our business and organizational structure efficiently. AAMC has agreed not to provide the same or substantially similar services to any other party so long as we and our operating partnership have on hand an average of $50.0 million in capital available for investment over the previous two fiscal quarters. Notwithstanding the foregoing, AAMC may engage in any other business or render similar or different services to others including, without limitation, the direct or indirect sponsorship or management of other investment based accounts or commingled pools of capital, however structured, having investment objectives similar to those of us or our operating partnership, so long as its services to us and our operating partnership are not impaired thereby.
	Incentive Management Fee
	Under the asset management agreement, we pay AAMC a quarterly incentive management fee as follows:
	(i)	2% of all cash available for distribution by us to our stockholders and to AAMC as incentive management fee, which we refer to as “available cash,” until the aggregate amount per share of available cash for the quarter (based on the average number of shares of our common stock outstanding during the quarter), which we refer to as the “quarterly per share distribution amount,” exceeds $0.161, then
	(ii)	15% of all additional available cash for the quarter until the quarterly per share distribution amount exceeds $0.193, then
	(iii)	25% of all additional available cash for the quarter until the quarterly per share distribution amount exceeds $0.257, and thereafter
	(iv)	50% of all additional available cash for the quarter.
	in each case set forth in clauses (i) through (iv), as such amounts may be appropriately adjusted from time to time to take into account the effect of any stock split, reverse stock split or stock dividend.
	We distribute any quarterly distribution to our stockholders after the application of the incentive management fee payable to AAMC.
	Expense Reimbursement
	We are required to reimburse AAMC on a monthly basis for the (i) direct and indirect expenses AAMC incurs or payments it makes on our behalf, including, but not limited to, the allocable compensation and routine overhead expenses of all employees and staff of AAMC and (ii) all other reasonable operating and overhead expenses AAMC incurs related to the asset management services it provides to us.
	Termination
	We may terminate the asset management agreement without cause upon the determination of at least two-thirds of our independent directors that (i) there has been unsatisfactory performance by AAMC that is materially detrimental to us, or (ii) the compensation payable to AAMC under the asset management agreement is unreasonable, unless AAMC agrees to compensation that at least two-thirds of our independent directors determine is reasonable.
	AAMC may terminate the asset management agreement without cause by providing written notice to us no later than 180 days prior to December 21 of any year during the initial term or a renewal term, and the asset management agreement will terminate effective on the December 21 next following the delivery of such notice.
	We will be required to pay AAMC a termination fee in the event that the asset management agreement is terminated as a result of (i) a termination by us without cause, (ii) a termination by AAMC as a result of our becoming regulated as an “investment company” under the Investment Company Act, or (iii) a termination by AAMC if we default in the performance of any material term of the asset management agreement (subject to a notice and cure period).
	The termination fee will be equal to three times the average annual incentive management fee earned by AAMC during the prior 24-month period immediately preceding the date of termination, calculated as of the end of the most recently completed fiscal quarter prior to the date of termination.
	If the asset management agreement were terminated by AAMC, our financial position and future prospects for revenues and growth could be materially adversely affected.
	Agreements with Altisource
	We have engaged Altisource to provide services for us as detailed below. If for any reason Altisource is unable to perform the services described under these agreements at the level and/or the cost that we anticipate, alternate service providers may not be readily available on favorable terms, or at all which could adversely affect our performance. Altisource’s failure to perform the services under these agreements with AAMC or us could have a material adverse effect on us.
	Master Services Agreement
	Under the master services agreement, Altisource provides property management, leasing and renovation management services associated with the single-family rental properties we acquire upon conversion of residential mortgage loans that continue to be sub-performing or non-performing. The agreement provides for an initial term of 15 years, which term will automatically renew for successive two-year terms unless either party sends a notice of non-renewal to the other party at least nine months before the completion of the initial or renewal term, as applicable. AAMC works directly with Altisource’s vendor management team on our behalf, and AAMC’s construction management team often interfaces with the general contractors and vendors to maintain relationships with the vendor network. Through AAMC’s team, we coordinate with Altisource and its personnel as well as the vendor network to establish a collective approach to the renovation management, maintenance, repair and materials supply chain. We believe AAMC’s experience and these coordinated efforts with Altisource provide it with the capabilities to replicate Altisource’s vendor network, if necessary.
	The total fees incurred by us under this agreement will be dependent upon the property management, leasing and renovation management services required on an asset-specific basis and will vary significantly based upon the location and condition of the asset as well as current market conditions and tenant turnover.
	In the event our asset management agreement with AAMC is terminated without cause by us, the master services agreement with Altisource may be terminated at its sole discretion.
	Support Services Agreement
	Under the support services agreement, Altisource may provide services to us in such areas as human resources, vendor management operations, corporate services, risk management, quality assurance, consumer psychology, treasury, finance and accounting, legal, tax, compliance and other support services where we may need assistance and support. The support services agreement provides generally that Altisource will undertake to provide the support services in a manner generally consistent with the manner and level of care with which such service, if any, was performed or provided prior to our separation from Altisource. The support services agreement extended for two years after the separation and automatically renews every year thereafter, but may be terminated earlier under certain circumstances including a default. The fees for all support services provided pursuant to the support services agreement are based on the fully-allocated cost of providing the service. “Fully-allocated cost” means the all-in cost of providing such service, including direct charges and allocable amounts reflecting compensation and benefits, technology expenses, occupancy and equipment expense and third-party payments (but not taxes incurred in connection therewith).
	Although the support services agreement has enabled us to grow our business, AAMC is in the process of internalizing the support services that had been provided to us by Altisource through its direct employment of the 26 employees that currently are providing these services to us through the support services agreement.
	The total fees incurred by us under this agreement are dependent upon our business activity and the level of services required in connection therewith. In the event our asset management agreement with AAMC expires or is terminated, the support services agreement will terminate within 30 days.
	Tax Matters Agreement
	The tax matters agreement with Altisource sets out each party’s rights and obligations with respect to deficiencies and refunds, if any, of Luxembourg, U.S. federal, state, local or other foreign taxes for periods before and after our separation from Altisource and related matters such as the filing of tax returns and the conduct of IRS and other audits. In general, under this agreement, we are responsible for taxes attributable to our business incurred after the separation, and Altisource is responsible for taxes attributable to our business incurred prior to the separation.
	Trademark License Agreement
	Under the trademark license agreement, Altisource granted us a non-exclusive, non-transferable, non-sublicensable, royalty free license to use the name “Altisource.” The agreement has no specified term and may be terminated by either party upon 30 days’ written notice, with or without cause. In the event that this agreement is terminated, all rights and licenses granted thereunder, including, but not limited to, the right to use “Altisource” in our name will terminate.
	In the event our asset management agreement with AAMC expires or is terminated, the trademark license agreement will terminate within 30 days.
	Agreements with Ocwen
	Servicing Agreement
	Under the servicing agreement, Ocwen services our acquired residential mortgage loans and provides loan modification, assisted deed-in-lieu, assisted deed-for-lease and other loss mitigation programs. The agreement provides for an initial term of 15 years. In the event our asset management agreement with AAMC expires or is terminated, the servicing agreement will terminate within 30 days. Through 2014, we had exclusively engaged Ocwen to service the residential mortgage loans in our portfolio.
	Ocwen has been and is subject to a number of pending regulatory investigations, inquiries, requests for information and legal proceedings that could result in adverse regulatory or other actions against Ocwen.  As a result of these various difficulties faced by Ocwen, its debt and servicer ratings have been downgraded. Given the recent challenges and regulatory scrutiny faced by Ocwen, we have engaged additional alternate servicers to service our loans. We have begun to move certain loans to these new servicers to diversify our servicing options. However, a substantial number of the loans we own continue to be serviced by Ocwen. It is possible, even as we transfer all or a portion of our mortgage loan portfolio to such other servicers, the alternate servicers may not be able to service our loans or resolve our non-performing loans. If for any reason, our mortgage servicers are unable to service these loans at the level and/or the cost that we anticipate, or if we fail to pay or otherwise default under the servicing agreements, and our mortgage servicers cease to act as our servicers, alternate servicers may not be readily available on favorable terms, or at all, which could have a material adverse effect on us..
	The total fees incurred by us under this agreement are dependent upon the number and type of acquired residential mortgage loans that Ocwen services pursuant to the terms of the agreement.
	Aircraft Time Sharing Agreement with Ocwen
	On October 8, 2013, we entered into an Aircraft Time Sharing Agreement, or the “Timeshare Agreement,” with Ocwen pursuant to which Ocwen will make its corporate plane available to us for business-related travel from time to time. Under the Time Sharing Agreement, Ocwen agreed to provide us, on a time sharing basis, access to its plane in consideration of our reimbursement to Ocwen of the sum of its direct expenses of operating the plane plus an additional charge equal to 100% of such expenses. The amounts actually charged to us in any period will directly correlate to our use of the aircraft in each period, which will vary depending on our needs and business use.

The master repurchase agreement requires the TRS to repurchase the Class M Notes from NewSource at a 5.0% yield on December 28, 2014, with the parties having the option to extend the master repurchase agreement for an additional 89 day period. In no event can the master repurchase agreement be extended beyond September 29, 2015.
	During the year ended December 31, 2013, we acquired a portfolio from Ocwen of non-performing first lien residential mortgage loans having aggregate market value of underlying properties of $94 million. The aggregate purchase price for this portfolio was $64 million.

	Stock options
	On December 21, 2012, as part of our separation transaction from Altisource, we issued stock options under the 2012 Conversion Option Plan and 2012 Special Conversion Option Plan to holders of Altisource stock options to purchase shares of our common stock in a ratio of one share of our common stock to every three shares of Altisource common stock. The options were granted as part of our separation to employees of Altisource and/or Ocwen solely to give effect to the exchange ratio in the separation, and we do not include share-based compensation expense related to these options in our consolidated statements of operations because they are not related to our incentive compensation.
	The following table sets forth the activity of our outstanding options:

Of these exercisable options, none had exercise prices higher than the market price of our common stock as of December 31, 2014.
	Restricted stock
	Our directors each receive annual grants of restricted stock equal to $45,000 based on the market value of our common stock at the time of the annual stockholders meeting. This restricted stock vests and is issued after a one-year service period subject to each director attending at least 75% of the Board and committee meetings. No dividends are paid on the shares until the award is issued. During the year ended December 31, 2014 and 2013, we granted 8,245 and 16,355 shares of stock, respectively, pursuant to our 2013 Director Equity Plan with weighted average grant date fair value per share of $27.28 and $18.47, respectively.
	We recorded $0.2 million and $0.2 million of compensation expense related to these grants for the year ended December 31, 2014 and 2013, respectively.

	As a REIT, we must meet certain organizational and operational requirements including the requirement to distribute at least 90% of our annual REIT taxable income excluding capital gains to our stockholders. As a REIT, we generally will not be subject to federal income tax to the extent we distribute our REIT taxable income to our stockholders and provided we satisfy the REIT requirements including certain asset, income, distribution and stock ownership tests. If we fail to qualify as a REIT, and do not qualify for certain statutory relief provisions, we will be subject to U.S. federal, state and local income taxes and may be precluded from qualifying as a REIT for the subsequent four taxable years following the year in which we lost our REIT qualification.
	Based on our 2014 taxable income of $115.8 million, which includes net capital gains of $54.4 million, the aggregate minimum distribution to stockholders required to maintain our REIT status was $55.3 million in 2014. Dividends declared and paid per share of common stock aggregated $2.03 for the year ended December 31, 2014, or $116.0 million. These distributions included a cash dividend paid on March 10, 2014 of $0.08 per share of common stock, or $4.5 million, which was intended to satisfy the requirement that a REIT must distribute at least 90% of its annual REIT taxable income to its stockholders and was treated as a 2013 distribution for REIT qualification purposes.
	Our consolidated financial statements include the operations of our taxable REIT subsidiary ("TRS"), which is subject to federal, state and local income taxes on its taxable income. From inception through December 31, 2014, the TRS operated at a cumulative taxable loss, which resulted in our recording a deferred tax asset with a corresponding valuation allowance.
	We recorded state income tax expense on our consolidated operations for the year ended December 31, 2014. As a REIT, we may also be subject to federal taxes if we engage in certain types of transactions.
	As of December 31, 2014 and 2013, we did not accrue interest or penalties associated with any unrecognized tax benefits, nor was any interest expense or penalty recognized during the year ended December 31, 2014 and 2013. We recorded nominal state and local tax expense on income and property for the year ended December 31, 2014.

	(1) Shares weighted by period outstanding since the separation on December 21, 2012.
	Because we incurred a net loss for the period from March 15, 2012 (inception) to December 31, 2012, basic and diluted earnings per share are equivalent. For the period from March 15, 2012 (inception) to December 31, 2012 there were 276,100 stock options excluded from the calculation of diluted earnings per share because inclusion would have been anti-dilutive, which shares are weighted by period outstanding since the separation on December 21, 2012.

Summary_of_significant_account1

Summary of significant accounting policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Cash and cash equivalents	Cash equivalents
	We consider highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.
Comprehensive income	Comprehensive income
	Because comprehensive income (loss) equals net income (loss), separate statements of comprehensive income (loss) are not presented as part of our consolidated financial statements.
Concentration of credit risk	Concentration of credit risk
	We maintain our cash and cash equivalents at banking institutions. Certain account balances exceed FDIC insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage.
Earnings per share	Earnings per share
	Basic earnings per share is computed by dividing net income (loss) by the weighted average common stock outstanding during the period. Diluted earnings per share is computed by dividing net income (loss) by the weighted average common stock outstanding for the period plus the dilutive effect of stock options and restricted stock outstanding using the treasury stock method and if converted method, respectively.
Expense reimbursement and incentive management fees	Expense reimbursement and incentive management fee
	Our asset manager's primary business is asset management. In its role as our asset manager, AAMC incurs indirect costs (e.g. payroll and overhead) related to managing our business which are contractually reimbursable by us. AAMC allocates indirect costs to us as incurred by estimating the percentage of time spent for our benefit.
	The incentive management fee we pay to our Manager is based on the quarterly cash available for distribution to our stockholders. Pursuant to our asset management agreement, our Manager's incentive management fee structure entitles it to receive a share of our cash flow available for distribution to our stockholders. If we do not generate taxable income that is distributable to our stockholders, then we will not be required to pay incentive management fees.
Fair value of financial instruments	Fair value of financial instruments
	We designate fair value measurements into three levels based on the lowest level of substantive input used to make the fair value measurement. Those levels are as follows:
	•	Level 1 - Quoted prices in active markets for identical assets or liabilities.
	•	Level 2 - Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities.
	•	Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
Income tax	Income taxes
	We believe that we have complied and will continue to comply with the provisions of the federal income tax code applicable to REITs beginning for the year ended December 31, 2013 and elected REIT status upon filing of our 2013 income tax return. Accordingly, we believe that we will not be subject to federal income tax beginning in the year ended December 31, 2013 and going forward on the portion of our REIT taxable income that is distributed to our shareholders as long as certain asset, income and share ownership tests are met. If after electing to be taxed as a REIT, we subsequently fail to qualify as a REIT in any taxable year, we generally will not be permitted to qualify for treatment as a REIT for federal income tax purposes for the four taxable years following the year during which qualification is lost.
	Our TRSs will be subject to federal and state income taxes. Income taxes are provided for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted rates expected to apply to taxable income in the years in which management expects those temporary differences to be recovered or settled. The effect on deferred taxes of a change in tax rates is recognized in income in the period in which the change occurs. Subject to our judgment, we reduce a deferred tax asset by a valuation allowance if it is “more likely than not” that some or all of the deferred tax asset will not be realized. Tax laws are complex and subject to different interpretations by the taxpayer and respective governmental taxing authorities. Significant judgment is required in evaluating tax positions, and we recognize tax benefits only if it is more likely than not that a tax position will be sustained upon examination by the appropriate taxing authority.
Mortgage loans	Mortgage loans
	Upon the acquisition of mortgage loans, we record the assets at fair value which is the purchase price we paid for the loans on the acquisition date. Mortgage loans are subsequently accounted for at fair value under the fair value option election with unrealized gains and losses recorded in current period earnings. We have concluded that mortgage loans accounted for at fair value timely reflect the results of our investment performance.
	We determine the purchase price for mortgage loans at the time of acquisition by using a discounted cash flow valuation model and considering alternate loan resolution probabilities including modification, liquidation or conversion to rental property. Observable inputs to the model include current interest rates, loan amounts, status of payments and property types. Unobservable inputs to the model include discount rates, forecast of future home prices, alternate loan resolution probabilities, resolution timelines and the value of underlying properties.
	After mortgage loans are acquired, the fair value of each loan is adjusted in each subsequent reporting period as the loan proceeds to a particular resolution (i.e., modification, or conversion to real estate owned). As a loan approaches resolution, the resolution timeline for that loan decreases and costs embedded in the discounted cash flow model for loan servicing, foreclosure costs and property insurance are incurred and removed from future expenses. The shorter resolution timelines and reduced future expenses each increase the fair value of the loan. The increase in the value of the loan is recognized in net unrealized gain on mortgage loans in our consolidated statements of operations.
	We also recognize unrealized gains and losses in the fair value of the loans in each reporting period when our mortgage loans are transferred to real estate owned. The transfer to real estate owned occurs when we have obtained title to the property through completion of the foreclosure process. The fair value of these assets at the time of transfer to real estate owned is estimated using BPOs.
	AAMC’s capital markets group determines the fair value of mortgage loans monthly and has developed procedures and controls governing the valuation process relating to these assets. The capital markets group reports to our Investment Committee, a committee of our Chief Executive Officer and our Chairman that oversees and approves the valuations. The capital markets group also monitors the valuation model for performance against actual results which is reported to the Investment Committee and used to continuously improve the model.
Loans held for sale	Loans held for sale
	Loans held for sale, which consist of re-performing residential mortgage loans acquired from others, are recorded at the lower of cost or fair value. We do not originate loans. During 2014, management decided to sell certain re-performing loans and as such they were reclassified as loans held for sale from loans held for investment.
Real estate impairment	Real estate impairment
	With respect to residential rental properties classified as held for use, we perform an impairment analysis using estimated cash flows if events or changes in circumstances indicate that the carrying value may be impaired, such as prolonged vacancy, identification of materially adverse legal or environmental factors, changes in expected ownership period or a decline in market value to an amount less than cost. This analysis is performed at the property level. These cash flows are estimated based on a number of assumptions that are subject to economic and market uncertainties including, among others, demand for rental properties, competition for customers, changes in market rental rates, costs to operate each property and expected ownership periods.
	If the carrying amount of a held for use asset exceeds the sum of its undiscounted future operating and residual cash flows, an impairment loss is recorded for the difference between estimated fair value of the asset and the carrying amount. We generally estimate the fair value of assets held for use by using BPOs. In some instances, appraisal information may be available and is used in addition to BPOs.
Residential properties	Residential properties
	Upon the acquisition of real estate, generally through the completion of foreclosure, we record the residential property at fair value as of the acquisition date as a component of real estate owned based on information obtained from a broker's price opinion, a full appraisal or the price given in a current contract of sale of the property. After a short evaluation period, we perform property renovations to maximize the value of the property for our rental strategy. Such expenditures are part of our initial investment in a property and, therefore, are classified as investing activities in our consolidated statement of cash flows. Subsequently, the residential property, including any renovations that improve or extend the life of the asset, are accounted for at cost. The cost basis is depreciated using the straight-line method over an estimated useful life of three to 27.5 years based on the nature of the components. Interest and other carrying costs incurred during the renovation period are capitalized until the property is ready for its intended use. Expenditures for ordinary maintenance and repairs are charged to expense as incurred.
	Expenditures directly related to successful leasing efforts such as lease commissions are included in deferred leasing and financing costs, net and are stated at amortized cost. Such expenditures are part of our operations and, therefore, are classified as operating activities in our consolidated statement of cash flows. Capitalized leasing costs are amortized on a straight-line basis over the lease term of the respective leases which generally are from one to 2 years.
	Residential properties are classified either as held for use or held for sale. Residential properties are classified as real estate and related assets held for sale when sale of the assets has been formally approved and is expected to occur in the next twelve months. We record residential properties held for sale at the lower of the carrying amount or estimated fair value less costs to sell. The impairment loss is the amount by which the carrying amount exceeds the estimated fair value less costs to sell.
Residential rental revenues	Residential rental revenues
	Minimum contractual rents from leases are recognized on a straight-line basis over the terms of the leases in residential rental revenues. Therefore, actual amounts billed in accordance with the lease during any given period may be higher or lower than the amount of rental revenue recognized for the period. Straight-line rental revenue commences when the customer takes control of the leased premises. Deferred rents receivable, net represents the amount by which straight-line rental revenue exceeds rents currently billed in accordance with lease agreements. Contingent rental revenue is accrued when the contingency is removed. Termination fee income is recognized when the customer has vacated the rental property, the amount of the fee is determinable and collectability is reasonably assured.
	Rents receivable, net and deferred rents receivable, net are reduced by an allowance for amounts that become uncollectible. We regularly evaluate the adequacy of our allowance for doubtful accounts. The evaluation takes into consideration the aging of accounts receivable and our analysis of customer personal profile and review past due account balances. Rents receivable, net and deferred rents receivable, net are written-off when we have deemed that the amounts are uncollectible.
Restricted cash	Restricted cash
	Restricted cash represents cash deposits that are legally restricted or held by third parties on our behalf, such as escrows and reserves for debt service established pursuant to certain of our repurchase agreements.

	We account for our investment in NewSource using the cost method because we do not exercise significant influence over NewSource. As a result, we recognize preferred dividend income from this investment when received.
