Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation We prepare our condensed consolidated financial statements and footnotes in accordance with accounting principles generally accepted in the United States of America, or GAAP, as contained in the Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC. All intercompany transactions and accounts have been eliminated in consolidation.
Reclassifications	Certain reclassifications have been made to the prior year amounts to conform to the current year presentation.
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 reported amounts in the condensed consolidated financial statements and accompanying notes. Significant estimates include allowance for loan losses, valuation of warrants, stock-based compensation expense, servicing assets/liabilities, loans purchased, capitalized software development costs, the useful lives of long-lived assets and valuation allowance for deferred tax assets. We base our estimates on historical experience, current events and other factors we believe to be reasonable under the circumstances. These estimates and assumptions are inherently subjective in nature; actual results may differ from these estimates and assumptions.
Recently Adopted Accounting Standards and Recent Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Standards In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 simplifies several aspects of accounting for share-based payment award transactions which include the income tax consequences, classification of awards as either equity or liabilities, classification on the statement of cash flows and forfeiture rate calculations. We adopted the new standard effective January 1, 2017. The adoption of this standard did not have a material impact on our consolidated financial statements and no prior period amounts were adjusted. Recent Accounting Pronouncements Not Yet Adopted In May 2014, the FASB issued ASU 2014-09, Revenue Recognition, which creates ASC 606, Revenue from Contracts with Customers, and supersedes ASC 605, Revenue Recognition. ASU 2014-09 requires revenue to be recognized in an amount that reflects the consideration to which the entity expects to be entitled in exchange for goods or services and also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows from customer contracts. The new standard will be effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early adoption is permitted for annual reporting periods beginning after December 15, 2016. In March 2016, the FASB issued ASU 2016-08, Principal versus Agent Considerations, which makes amendments to the new revenue standard on assessing whether an entity is a principal or an agent in a revenue transaction and impacts whether an entity reports revenue on a gross or net basis. In April 2016, the FASB issued ASU 2016-10, Identifying Performance Obligations and Licensing, which makes amendments to the new revenue standard regarding the identification of performance obligations and accounting for the license of intellectual property. In May 2016, the FASB issued ASU 2016-12, Narrow-Scope Improvements and Practical Expedients, which makes amendments to the new revenue standard regarding assessing collectibility, presentation of sales taxes, noncash consideration and completed contracts and contract modifications at the time of transition to the new standard. Each amendment has the same effective date and transition requirements as the new revenue recognition standard. We completed our initial assessment of the impact of the new revenue standard noting that revenue generated in accordance with ASC 310, Receivables, and ASC 860, Transfers and Servicing, is explicitly excluded from the scope of ASC 606. Accordingly, we have concluded that our interest income, gains on loan sales and loan servicing income will not be affected by the adoption of ASC 606. Marketing fees from our issuing bank partner will be within the scope of ASC 606. We will adopt the requirements of the new standard effective January 1, 2018 and intend to apply the modified retrospective method of adoption with the cumulative effect of adoption, if material, recognized at the date of initial application. We believe that ASC 606 will have little, if any, impact on the timing and amount of revenue recognition as compared to the current standard and that there will be no material impact upon adoption. In February 2016, the FASB issued ASU 2016-02, Leases, which creates ASC 842, Leases, and supersedes ASC 840, Leases. ASU 2016-02 requires lessees to recognize a right-of-use asset and lease liability for all leases with terms of more than 12 months. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The new standard will be effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period and is applied retrospectively. Early adoption is permitted. We are currently assessing the impact that the adoption of this standard will have on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments. ASU 2016-13 will change the impairment model and how entities measure credit losses for most financial assets. The standard requires entities to use the new expected credit loss impairment model which will replace the incurred loss model used today. The new standard will be effective for annual reporting periods beginning after December 15, 2019. Early adoption is permitted, but not prior to December 15, 2018. We are currently assessing the impact that the adoption of this standard will have on our consolidated financial statements.
Fair Value Measurement	Because our loans held for investment, loans held for sale and fixed-rate debt are not measured at fair value, we are required to disclose their fair value in accordance with ASC 825. Due to the lack of transparency and comparable loans, we utilize an income valuation technique to estimate fair value. We utilize industry-standard modeling, such as discounted cash flow models, to arrive at an estimate of fair value and may utilize third-party service providers to assist in the valuation process. This determination requires significant judgments to be made. We evaluate our financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level at which to classify them for each reporting period. Due to the lack of transparency and quantity of transactions related to trades of servicing rights of comparable loans, we utilize an income valuation technique to estimate fair value. We utilize industry-standard modeling, such as discounted cash flow models, to arrive at an estimate of fair value and may utilize third-party service providers to assist in the valuation process. This determination requires significant judgments to be made. Loans held for investment and loans held for sale - Fair value is based on discounted cash flow models which contain certain unobservable inputs such as discount rate, renewal rate and default rate. Fixed-rate debt - Our ODAST II Agreement and certain other agreements are considered fixed-rate debt. Fair value of our fixed-rate debt is based on a discounted cash flow model with an unobservable input of discount rate. For our variable rate debt, carrying value approximates fair value.
