Variable Interest Entity [Line Items]
Reclassifications	Reclassifications Certain reclassifications have been made to the 2014 consolidated financial statements to conform to the 2015 presentation.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements reflect the Company's accounts and the accounts of the Company's majority-owned and/or controlled subsidiaries. The Company follows the provisions of Accounting Standards Codification (“ASC”) Topic 810, Consolidation, and accordingly consolidates entities that are variable interest entities (“VIEs”) where it has determined that it is the primary beneficiary of such entities. Once it is determined that the Company holds a variable interest in a VIE, management must perform a qualitative analysis to determine (i) if the Company has the power to direct the matters that most significantly impact the VIE's financial performance; and (ii) if the Company has the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits of the VIE that could potentially be significant to the VIE. If the Company's interest possesses both of these characteristics, the Company is deemed to be the primary beneficiary and would be required to consolidate the VIE. The Company continually assesses its involvement with VIEs and re-evaluates the requirement to consolidate them. The portions of these entities that the Company does not own are presented as noncontrolling interests as of the dates and for the periods presented in the consolidated financial statements. All intercompany transactions and balances have been eliminated in the Company's consolidated financial statements.
Use of Estimates	Use of Estimates Preparation of the Company's consolidated financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and costs and expenses during the reporting period. The Company makes estimates of its allowance for credit losses, the valuation allowance against its deferred tax assets, discounts and collectability of management fees, the valuation of stock-based compensation, and in determining whether a decrease in the fair value of an investment is an other-than-temporary impairment. The real estate and financial fund management segments make assumptions in determining the fair value of investments in investment securities. Actual results could differ from these estimates.
Financing Receivables - Receivables from Managed Entities	Financing Receivables - Receivables from Managed Entities The Company performs a review of the collectability of its receivables from managed entities on a quarterly basis. If upon review there is an indication of impairment, the Company will analyze the future cash flows of the managed entity. With respect to the receivables from its commercial finance investment partnerships, this takes into consideration several assumptions by management, primarily concerning estimates of future bad debts and recoveries. For receivables from the real estate investment entities, the Company estimates the cash flows through the sale of the underlying properties based on projected net operating income as a multiple of published capitalization rates, as reduced by the underlying mortgage balances and priority distributions due to the investors.
Investment Securities	Investment Securities The Company’s investment securities available-for-sale, including investments in the CLO and CDO issuers it sponsored, are carried at fair value. The fair value of the CLO and CDO investments is based primarily on internally-generated expected cash flow models that require significant management judgment and estimates due to the lack of market activity and the use of unobservable pricing inputs. The Company's investments in the common stock of The Bancorp, Inc. (NASDAQ: TBBK), Resource Credit Income Fund ("CIF") (NASDAQ: RCIIX), and Resource Real Estate Diversified Income Fund ("DIF") (NASDAQ: RREDX), all of which are affiliated entities, are valued at the closing prices of the respective publicly-traded stocks. The Company's investment in Resource Real Estate Global Property Securities ("RREGPS"), a Company-sponsored and managed Australian investment fund, was valued at net asset value. In July 2015, the Company redeemed its interest in RREGPS and terminated its management agreement. The cumulative net unrealized gains (losses) on these investment securities, net of tax, is reported through accumulated other comprehensive income (loss). Realized gains (and losses) on the sale of investments are determined on the trade date on the basis of specific identification and are included in net operating results. Securities that are held principally for resale in the near term (trading securities) are recorded at fair value with changes in fair value recorded in earnings.
Recent Accounting Standards	Recent Accounting Standards Newly-Adopted Accounting Principle The Company’s adoption of the following standard during the nine months ended September 30, 2015 did not have a material impact on its consolidated financial position, results of operations or cash flows: In April 2014, the Financial Accounting Standards Board ("FASB") issued authoritative guidance to change the criteria for reporting discontinued operations. Under the new guidance, only disposals representing a strategic shift in a company's operations and financial results should be reported as discontinued operations, with expanded disclosures. In addition, disclosure of the pre-tax income attributable to a disposal of a significant part of an organization that does not qualify as a discontinued operation is required. This guidance was effective for the Company as of January 1, 2015. Accounting Standards Issued But Not Yet Effective In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, which will replace most of the existing revenue recognition guidance in GAAP. The core principle of the ASU is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. The ASU requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. The ASU will be effective for the Company beginning January 1, 2018, including interim periods in 2018, and allows for both retrospective and prospective methods of adoption. The Company is in the process of determining the method of adoption and assessing the impact of this ASU on its consolidated financial statements. In June 2014, the FASB issued ASU No. 2014-12, Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide that a Performance Target Could be Achieved after the Requisite Service Period. ASU 2014-12 requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. The guidance is effective for the Company beginning January 1, 2016. The Company is currently evaluating the impact of the new guidance on its financial statements and has not yet selected a transition approach to implement the standard. In January 2015, the FASB issued ASU No. 2015-01, Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items, which eliminates from GAAP the concept of an extraordinary item. As a result, an entity will no longer be required to segregate extraordinary items from the results of ordinary operations, to separately present an extraordinary item on its income statement, net of tax, after income from continuing operations or to disclose income taxes and earnings per share data applicable to an extraordinary item. However, presentation and disclosure guidance for items that are unusual in nature and occur infrequently will be retained. Adoption of this ASU will be required on a prospective or retrospective basis beginning with the quarter ending March 31, 2016 and is not expected to have a material impact on the Company's consolidated financial statements. In February 2015, the FASB issued ASU No. 2015-02, Consolidation—Amendments to the Consolidation Analysis (Topic 810). The guidance requires an entity to evaluate whether it should consolidate certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. Specifically, the amendments: (1) modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities ("VIEs") or voting interest entities; (2) eliminate the presumption that a general partner should consolidate a limited partnership; (3) affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships; and (4) provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. This guidance is effective for the Company beginning January 1, 2016. Early application is permitted. The Company is currently evaluating the potential impact of this standard on its consolidated financial statements, as well as the available transition methods. In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The update requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability instead of being presented as an asset. Debt disclosures will include the face amount of the debt liability and the effective interest rate. The update requires retrospective application and represents a change in accounting principle. The update is effective for the Company beginning January 1, 2016. Early adoption is permitted for financial statements that have not been previously issued. ASU 2015-03 is not expected to have a material impact on the Company’s consolidated financial statements.
