Organization	Organization
	Inland American Real Estate Trust, Inc., which on April 16, 2015, changed its name to InvenTrust Properties Corp. (the "Company"), was formed on October 4, 2004 (inception) to acquire and manage a diversified portfolio of commercial real estate, primarily retail, office, industrial, multi-family (both conventional apartments and student housing), and lodging properties, located in the United States. The Company was party to a business management agreement with Inland American Business Manager and Advisor, Inc. (the "Business Manager") pursuant to which it served as the Company's business manager, with responsibility for overseeing and managing its day-to-day operations, under the supervision of the Company's board of directors. The Company was also party to property management agreements with each of its property managers (the "Property Managers").
	On March 12, 2014, the Company began the process of becoming fully self-managed by terminating its business management agreement, hiring all of the employees of the Business Manager and acquiring the assets of its Business Manager necessary to perform the functions previously performed by the Business Manager. Similarly, as of March 12, 2014, certain functions performed by the Property Managers, such as property-level accounting, lease administration, leasing, marketing and construction functions, were transitioned to the Company. The self-management transactions were completed on December 31, 2014 when the Company acquired the assets of its property managers and hired substantially all of its employees and the remaining property management functions were transitioned to the Company.
	On February 3, 2015, the Company completed the previously announced spin-off (the "Spin-Off") of its lodging subsidiary, Xenia Hotels & Resorts, Inc. ("Xenia"), through a taxable pro-rata distribution by the Company of 95% of the outstanding common stock of Xenia to holders of record of the Company’s common stock as of the close of business on January 20, 2015 (the “Record Date”). Each holder of record of the Company’s common stock received one share of Xenia’s common stock for every eight shares of the Company’s common stock held at the close of business on the Record Date. In lieu of fractional shares, stockholders of the Company received cash. On February 4, 2015, Xenia’s common stock began trading on the New York Stock Exchange (“NYSE”) under the ticker symbol “XHR.” In connection with the Spin-Off, the Company entered into certain agreements that, among other things, provide a framework for the Company’s relationship with Xenia after the Spin-Off, including a Transition Services Agreement, an Employee Matters Agreement and an Indemnity Agreement. Following the Spin-Off, the Company no longer has a lodging segment. Therefore, the 46 lodging assets included in the Spin-Off have been classified as discontinued operations as the Spin-Off represents a strategic shift that has had a major effect on the Company's operations and financial results. The assets and liabilities of these 46 lodging assets are classified as assets and liabilities of discontinued operations on the consolidated balance sheet at December 31, 2014. The operations of these 46 lodging assets have been classified as income from discontinued operations on the consolidated statement of operations and comprehensive income for the three months ended March 31, 2015 and 2014.
	The accompanying consolidated financial statements include the accounts of the Company, as well as all wholly owned subsidiaries and consolidated joint venture investments. Wholly owned subsidiaries generally consist of limited liability companies (LLCs) and limited partnerships (LPs). The effects of all significant intercompany transactions have been eliminated.
	Each property is owned by a separate legal entity which maintains its own books and financial records and each entity's assets are not available to satisfy the liabilities of other affiliated entities, except as otherwise disclosed in "Note 8. Debt".
	At March 31, 2015, the Company owned 142 properties, in which the operating activity is reflected in continuing operations on the consolidated statements of operations and comprehensive income for the three months ended March 31, 2015 and 2014. At December 31, 2014, the Company owned 188 properties, of which 46 lodging assets were included in the Spin-Off and classified as assets of discontinued operations. At March 31, 2014, the Company owned 272 properties, and additionally classified ten properties as held for sale.
	The breakdown, by segment, of the 142 owned properties at March 31, 2015 is as follows:
	Segment	Property Count	Square Feet / Beds
	Retail	108	15,477,279	Square feet
	Student Housing	14	7,989	Beds
	Non-core	20	6,409,697	Square feet

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies
	The accompanying consolidated financial statements have been prepared in accordance with GAAP and require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.
	Refer to the Company's audited financial statements for the year ended December 31, 2014, as certain note disclosures contained in such audited financial statements have been omitted from these interim consolidated financial statements.
	Recently Issued Accounting Pronouncements
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in GAAP when it becomes effective, although it will not affect the accounting for rental related revenues. ASU No. 2014-09 is currently effective for financial statements issued for fiscal years and interim period beginning after December 31, 2016. Early adoption is prohibited. In April 2015, the FASB voted to propose an amendment to the ASU, deferring the effective date one year to annual reporting periods beginning after December 15, 2017 for public entities. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU No. 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.
	In February 2015, the FASB issued ASU 2015-02, Consolidation.  This update includes amendments that change the requirements for evaluating limited partnerships and similar entities for consolidation.  Under the new guidance, limited partnerships and similar entities will be considered variable interest entities ("VIEs") unless a scope exception applies.  As such, entities that consolidate limited partnerships and similar entities that are considered to be VIEs will be subject to VIE primary beneficiary disclosure requirements, and entities that do not consolidate a VIE will be subject to the disclosure requirements that apply to variable interest holders other than the primary beneficiary.  The new guidance also eliminates three of the six criteria for determining if fees paid to a decision maker or service provider are considered to be variable interest in a VIE and changes the criteria used to determine if variable interests in a VIE held by related parties of a reporting entity require the reporting entity to consolidate the VIE.  This standard will be effective for financial statements issued by public companies for annual and interim reporting periods beginning after December 15, 2015.  The Company does not expect the adoption of this standard to have a material impact on the Company's consolidated financial statements; however, the Company will continue to evaluate the potential impact.
	In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected. Upon adoption, the Company will apply the new guidance on a retrospective basis and adjust the balance sheet of each individual period presented to reflect the period-specific effects of applying the new guidance. This guidance is effective for the Company beginning January 1, 2016. The Company is continuing to evaluate this guidance; however, the Company does not expect its adoption to have a significant impact on the consolidated financial statements.

Discontinued Operations	Disposed Properties
	The Company sold no operating properties and one land parcel during the three months ended March 31, 2015 for a gross disposition price of $1,410. The Company sold 223 properties and surrendered one property to the lender for the three months ended March 31, 2014 for a gross disposition price of $1,112,300. For the three months ended March 31, 2015 and 2014, the Company had generated net proceeds from the sale of properties of $1,454 and $462,178, respectively. During the three months ended March 31, 2015 and 2014, the Company recorded a gain on sale of investment properties of $728 and $1,244, respectively, in continuing operations.
	In line with the Company's adoption of the new accounting standard governing discontinued operations during the year ended December 31, 2014, only disposals representing a strategic shift that have (or will have) a major effect on results and operations would qualify as discontinued operations. On February 3, 2015, the Company completed the previously announced spin-off of its lodging subsidiary, Xenia. The 46 assets included in the Spin-Off have been classified as discontinued operations as the Spin-Off represents a strategic shift that has had a major effect on the Company's operations and financial results. The assets and liabilities of these 46 assets are classified as assets and liabilities of discontinued operations on the consolidated balance sheet at December 31, 2014. The operations of these 46 assets have been classified as income from discontinued operations on the consolidated statement of operations and comprehensive income for the three months ended March 31, 2015 and 2014. The major classes of assets and liabilities of discontinued operations as of March 31, 2015 and December 31, 2014 were as follows:

Investment in Partially Owned Entities [Abstract]
Investment in Partially Owned Entities	Consolidated Entities
	During the fourth quarter 2013, the Company entered into two joint ventures to each develop a lodging property. The Company had ownership interests of 75% in each joint venture. These entities were considered VIEs as defined in FASB ASC 810 because the entities did not have enough equity to finance their activities without additional subordinated financial support. The Company determined it had the power to direct the activities of the VIEs that most significantly impacted the VIEs' economic performance, as well as the obligation to absorb losses of the VIEs that could have potentially been significant to the VIEs or the right to receive benefits from the VIEs that could have potentially been significant to the VIEs. As such, the Company had a controlling financial interest and was considered the primary beneficiary of each of these entities. Therefore, these entities were consolidated by the Company and are included as a part of assets and liabilities of discontinued operations on the consolidated balance sheet at December 31, 2014. These entities were included in the Spin-Off on February 3, 2015 and are no longer part of the Company.
	For the VIEs where the Company was the primary beneficiary, the following are the liabilities of the consolidated VIEs which were not recourse to the Company, and the assets that could only have been used to settle those obligations.

	Unconsolidated Entities
	The entities listed below are owned by the Company and other unaffiliated parties in joint ventures. Net income, distributions and capital transactions for these properties are allocated to the Company and its joint venture partners in accordance with the respective partnership agreements. Refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 for details of each unconsolidated entity.
	These entities are not consolidated by the Company and the equity method of accounting is used to account for these investments. Under the equity method of accounting, the net equity investment of the Company and the Company’s share of net income or loss from the unconsolidated entity are reflected in the consolidated balance sheets and the consolidated statements of operations and comprehensive income.

	(a)	On December 18, 2014, Cobalt sold all of its real estate assets, and the Company recognized its share of the gain on the sale of the assets in equity in earnings for the year ended December 31, 2014. The balance of this joint venture at March 31, 2015 reflects the Company's expected return of the joint venture's remaining cash assets.
	(b)	On February 4, 2013, the Company entered into a joint venture agreement with Gerding Edlen Investors, LLC ("GE") in order to develop, construct and manage a student housing community on the campus of the University of Oregon in Eugene, Oregon, which was completed later in 2013 and is now fully operational. The joint venture is known as 15th & Walnut Owner, LLC ("Eugene"). The Company contributed $5,200 for an equity stake of 62%. The Company analyzed the joint venture and determined it is a VIE because the entity did not have enough equity to finance its activities without additional subordinated financial support. The Company also considered its participating rights under the joint venture agreement and determined that such participating rights also required the agreement of GE, which equates to shared decision making ability, and therefore the Company did not have the power to direct the activities of the VIE that most significantly impacted the VIE's economic performance. As such, the Company has significant influence but does not control Eugene. Therefore, the Company does not consolidate this entity and accounts for its investment in the entity under the equity method of accounting.
	On February 21, 2014, the Company purchased its partners' interest in one joint venture, which resulted in the Company obtaining control of the venture. Therefore, as of March 31, 2014, the Company consolidated this entity, recorded the assets and liabilities of the joint venture at fair value, and recorded a gain of $4,481 on the purchase of this investment during the three months ended March 31, 2014. This gain is included as a discontinued operation on the consolidated statement of operations and comprehensive income for the three months ended March 31, 2014.
	For the three months ended March 31, 2015 and 2014, the Company recorded no impairment in its unconsolidated entities.

Related Party Transaction, Due from (to) Related Party [Abstract]
Transactions with Related Parties	Also on March 12, 2014, as part of the Self-Management Transactions, the Company entered into separate Amended and Restated Master Management Agreements (collectively, the “Amended Property Management Agreements”) with each of the Property Managers (excluding Holdco), pursuant to which the Property Managers continued to provide property management services to the Company through December 31, 2014, other than the property-level accounting, lease administration, leasing, marketing and construction functions that the Company began performing pursuant to the Master Modification Agreement. The Company transitioned the remaining property management functions on December 31, 2014. Many of the employees of the Company's former Business Manager and former Property Managers are now directly employed by the Company. The Amended Property Management Agreements terminated on December 31, 2014 pursuant to their terms.
	The following table summarizes the Company’s related party transactions for the three months ended March 31, 2015 and 2014.
		For the three months ended				Unpaid amounts as of
		March 31, 2015		March 31, 2014		March 31, 2015		December 31, 2014

	(a)	In connection with the closing of the Master Modification Agreement and termination of the business management agreement on March 12, 2014, the Company reimbursed the Business Manager for compensation and other ordinary course out-of-pocket expenses, which totaled approximately $3,401. In addition, the Company reimbursed the Property Managers approximately $249 for compensation and out-of-pocket expenses incurred between January 1, 2014 and March 12, 2014 for the Property Manager employees the Company hired at closing to approximate the economics as though the Company had hired such employees on January 1, 2014. These costs are reflected in general and administrative reimbursements above.
	In addition, the Company has directly retained affiliates of the Business Manager to provide back-office services that were provided to the Company through the Business Manager prior to the termination of the business management agreement. These service agreements are generally terminable without penalty by either party upon 60 days’ notice. These costs are reflected in general and administrative reimbursements above. During the year ended December 31, 2014, the Company sent termination notices for agreements with those affiliates of the Business Manager which provided information technology and investor services to the Company. During the three months ended March 31, 2015, the Company sent a termination notice for the agreement with those affiliates of the Business Manager which provided human resource services to the Company. The Business Manager and its related parties are entitled to reimbursement for general and administrative expenses of the Business Manager and its related parties relating to the Company's administration.
	Unpaid amounts of $411 as of December 31, 2014 are included in accounts payable and accrued expenses on the consolidated balance sheet.
	(b)	The Company paid a related party of the Business Manager to purchase and monitor its investment in marketable securities. The Company terminated this agreement during the three months ended March 31, 2015.
	(c)	As part of the Self-Management Transactions, select Property Management fees charged to the Company were reduced effective January 1, 2014 to reflect, among other things, the hiring of the Property Manager employees and the services that were no longer being performed by the Property Managers. The Amended Property Management Agreements reduced the property management fees charged in respect of most of the Company’s multi-tenant retail properties to 3.50% of gross income generated by the applicable property for the first six months of 2014, and reduced fees charged in respect of the Company’s multi-tenant office properties to 3.50% of gross income generated by the applicable property for the first six months of 2014. The Company also agreed to assume responsibility for the compensation-related expenses of the Property Manager employees hired by the Company effective March 1, 2014.
	Unpaid amounts of $75 as of December 31, 2014 are included in other liabilities on the consolidated balance sheet.
	In addition to these fees, the Property Managers received reimbursements of payroll costs for property level employees. The Company reimbursed the Property Managers and other affiliates $2,391 for the three months ended March 31, 2014.
	(d)	In connection with the closing of the Master Modification Agreement and termination of the business management agreement, the Company paid a business management fee for January 2014, which totaled approximately $3,333. The Company did not pay a business management fee subsequent to January 31, 2014. Pursuant to the letter agreement dated May 4, 2012, the business management fee was reduced for investigation costs exclusive of legal fees incurred in conjunction with the SEC matter. The Master Modification Agreement contained a ninety-day reconciliation of certain payments and reimbursements, including the January 2014 business management fee. The reconciliation was completed during the three months ended June 30, 2014, which resulted in $739 of SEC-related investigation costs and an adjusted January 2014 business management fee expense of $2,594. Pursuant to the March 12, 2014 Self-Management Transactions, the May 4, 2012 letter agreement by the Business Manager has been terminated.
	(e)	The Company pays a related party of the Business Manager 0.2% of the principal amount of each loan placed for the Company. Such costs are capitalized as loan fees and amortized over the respective loan term.
	As of March 31, 2015 and December 31, 2014, the Company had deposited $377 and $376, respectively, in Inland Bank and Trust, a subsidiary of Inland Bancorp, Inc., an affiliate of The Inland Real Estate Group, Inc.

Investment in Marketable Securities	Investment in Marketable Securities
	Investment in marketable securities of $283,829 and $154,753 at March 31, 2015 and December 31, 2014, respectively, consists primarily of preferred and common stock investments in other REITs and certain real estate related bonds which are classified as available-for-sale securities and recorded at fair value. The cost basis net of impairments of available-for-sale securities was $176,074 and $95,480 as of March 31, 2015 and December 31, 2014, respectively. The Company's investment in marketable securities includes a 5% ownership of the outstanding common stock of Xenia. The Company held an investment in Xenia securities reported at its fair value of $128,990 as of March 31, 2015. The cost basis of the Xenia securities held by the Company was $80,748 as of March 31, 2015, which is equal to 5% of the the net equity, at historical cost basis, contributed to Xenia at the time of the Spin-Off.
	Unrealized holding gains and losses on available-for-sale securities are excluded from earnings and reported as a separate component of comprehensive income until realized. The Company has net accumulated other comprehensive income related to its marketable securities portfolio of $107,755 and $59,273, which includes gross unrealized losses of $1,712 and $1,328 related to its marketable securities as of March 31, 2015 and December 31, 2014, respectively. Securities with gross unrealized losses have a related fair value of $9,384 and $11,502 as of March 31, 2015 and December 31, 2014, respectively. The unrealized gain on the Xenia securities held by the Company was $48,242 as of March 31, 2015.
	The Company’s policy for assessing recoverability of its available-for-sale securities is to record a charge against net earnings when the Company determines that a decline in the fair value of a security drops below the cost basis and believes that decline to be other-than-temporary. Factors in the assessment of other-than-temporary impairment include determining whether (1) the Company has the ability and intent to hold the security until it recovers, and (2) the length of time and degree to which the security’s price has declined. No impairment to available-for-sale securities was recorded for the three months ended March 31, 2015 and 2014.
	Dividend income is recognized when earned. During the three months ended March 31, 2015 and 2014, dividend income of $2,899 and $3,719, respectively, was recognized and is included in interest and dividend income on the consolidated statements of operations and comprehensive income.

	On February 3, 2015, the Company entered into an amended and restated credit agreement for a $300,000 unsecured revolving line of credit with KeyBank National Association, JP Morgan Chase Bank National Association and other financial institutions. The accordion feature allows the Company to increase the size of its unsecured line of credit up to $600,000, subject to certain conditions. The unsecured revolving line of credit matures on February 2, 2019 and contains one twelve-month extension option that the Company may exercise upon payment of an extension fee equal to 0.15% of the commitment amount on the maturity date and subject to certain other conditions. The unsecured revolving line of credit bears interest at a rate equal to LIBOR plus 1.40% and requires the maintenance of certain financial covenants.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements
	In accordance with ASC 820, Fair Value Measurement and Disclosures, the Company defines fair value based on the price that would be received upon sale of an asset or the exit price that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company uses a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value. The fair value hierarchy consists of three broad levels, which are described below:
	•	Level 1 - Quoted prices in active markets for identical assets or liabilities that the entity has the ability to access.
	•	Level 2 - Observable inputs, other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.
	•	Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.
	The Company has estimated the fair value of its financial and non-financial instruments using available market information and valuation methodologies the Company believes to be appropriate for these purposes. Considerable judgment and a high degree of subjectivity are involved in developing these estimates and, accordingly, they are not necessarily indicative of amounts that would be realized upon disposition.
	Recurring Measurements
	For assets and liabilities measured at fair value on a recurring basis, quantitative disclosure of the fair value for each major category of assets and liabilities is presented below:
			Fair Value Measurements at March 31, 2015

	Derivative interest rate instruments		—				(1,744		)		—
	Total liabilities		$	—			$	(1,744	)		$	—
	Level 1
	At March 31, 2015 and December 31, 2014, the fair value of the available-for-sale real estate equity securities have been valued based upon quoted market prices for the same or similar issues when current quoted market prices were available. Unrealized gains or losses on investment are reflected in unrealized gain (loss) on investment securities in comprehensive income on the consolidated statements of operations and comprehensive income.
	Level 2
	To calculate the fair value of the real estate related bonds and the derivative interest rate instruments, the Company primarily uses quoted prices for similar securities and contracts. For the real estate related bonds, the Company reviews price histories for similar market transactions. For the derivative interest rate instruments, the Company uses inputs based on data that is observed in the forward yield curve which is widely observable in the marketplace.  The Company also incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements which utilizes Level 3 inputs, such as estimates of current credit spreads. However, as of March 31, 2015 and December 31, 2014, the Company has assessed that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. As of March 31, 2015 and December 31, 2014, the Company had outstanding interest rate swap agreements with a notional value of $47,000 and $51,283, respectively.
	Level 3
	At March 31, 2015 and December 31, 2014, the Company had no level three recurring fair value measurements.
	Non-Recurring Measurements
	The following table summarizes activity for the Company’s assets measured at fair value on a non-recurring basis. The Company recognized certain impairment charges to reflect the investments at their fair values for the three months ended March 31, 2014. The asset groups that were reflected at fair value through this evaluation are:

	Investment Properties
	During the three months ended March 31, 2015, the Company recognized no impairment.
	During the three months ended March 31, 2014, the Company identified certain properties which may have a reduction in the expected holding period and reviewed the probability of these assets' dispositions. The Company's estimated fair value relating to the investment properties' impairment analysis was based on a comparison of letters of intent or purchase contracts, broker opinions of value and ten-year discounted cash flow models, which includes contractual inflows and outflows over a specific holding period. The cash flows consist of observable inputs such as contractual revenues and unobservable inputs such as forecasted revenues and expenses. These unobservable inputs are based on market conditions and the Company's expected growth rates. For those properties impaired during the three months ended March 31, 2014, the Company estimated fair value using letters of intent and purchase contracts.
	For the three months ended March 31, 2014, the Company recorded an impairment of investment properties of $6,841. Certain properties were impaired prior to disposal. There were no related impairment charges for those properties included in discontinued operations for the three months ended March 31, 2015. There were $2,998 related impairment charges for those properties included in discontinued operations for the three months ended March 31, 2014.

	The Company has elected and has operated so as to qualify to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the "Code"), commencing with the tax year ended December 31, 2005. So long as it qualifies as a REIT, the Company generally will not be subject to federal income tax on taxable income that is distributed to stockholders. A REIT is subject to a number of organizational and operational requirements including a requirement that it currently distribute at least 90% of its REIT taxable income (subject to certain adjustments) to its stockholders (the “90% Distribution Requirement”). If the Company fails to qualify as a REIT in any taxable year, without the benefit of certain relief provisions, the Company will be subject to federal and state income tax on its taxable income at regular corporate tax rates. Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income, property or net worth and federal income and excise taxes on its undistributed income. In addition, the Company owns substantially all of the outstanding stock of a subsidiary REIT, MB REIT (Florida), Inc. (“MB REIT”), which the Company consolidates for financial reporting purposes but which is treated as a separate REIT for federal income tax purposes.
	The Company has elected to treat certain of its consolidated subsidiaries, and may in the future elect to treat newly formed subsidiaries, as taxable REIT subsidiaries pursuant to the Internal Revenue Code. Taxable REIT subsidiaries may participate in non-real estate related activities and/or perform non-customary services for tenants and are subject to federal and state income tax at regular corporate tax rates. The Company's hotels were leased to certain of the Company's taxable REIT subsidiaries. Lease revenue from these taxable REIT subsidiaries and the Company's wholly-owned subsidiaries is eliminated in consolidation. For the three months ended March 31, 2015 and 2014, an income tax expense of $929 and $302, respectively, was included on the consolidated statements of operations and comprehensive income.

	The Company's current portfolio strategy is to tailor and grow the retail and student housing segments and dispose of the remaining non-core assets. The Company's objective has been, and will continue to be, maximizing stockholder value over the long-term. The non-core segment includes multi-tenant office and triple-net properties. The Company evaluates segment performance primarily based on net operating income. Net operating income of the segments excludes interest expense, depreciation and amortization, general and administrative expenses, net income of noncontrolling interest and other investment income from corporate investments. The non-segmented assets primarily include the Company’s cash and cash equivalents, investment in marketable securities, construction in progress, investment in unconsolidated entities and notes receivable.
	For the three months ended March 31, 2015, approximately 13% of the Company’s retail and non-core rental revenue from continuing operations was generated by three properties leased to AT&T, Inc. As a result of the concentration of revenue generated from these properties, if AT&T, Inc. were to cease paying rent or fulfilling its other monetary obligations, the Company could have significantly reduced rental revenues or higher expenses until the defaults were cured or the properties were leased to a new tenant or tenants. The student housing segment was not considered in this analysis as leases are on a per bed basis, for a year or less, and are immaterial when evaluated individually.
	The following table summarizes net property operations income by segment as of and for the three months ended March 31, 2015.

Earnings Per Share [Abstract]
Earnings (loss) per Share	Earnings (loss) per Share and Equity Transactions
	Basic earnings (loss) per share (“EPS”) are computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period (the "common shares"). Diluted EPS is computed by dividing net income (loss) by the common shares plus potential common shares issuable upon exercising options or other contracts. There is an immaterial amount of potentially dilutive common shares.
	The basic and diluted weighted average number of common shares outstanding was 861,824,777 and 912,594,434, for the three months ended March 31, 2015 and 2014, respectively.
	The Company completed a modified “Dutch Auction” tender offer for the purchase of up to $350,000 in value of shares of common stock (the “Offer”) on April 25, 2014. In accordance with rules promulgated by the SEC, the Company had the option to increase the number of shares accepted for payment in the Offer by up to 2% of the outstanding shares without amending or extending the Offer. To avoid any proration to the stockholders that tendered shares, the Company decided to increase the number of shares accepted for payment in the Offer. On May 1, 2014, the Company accepted for purchase 60,665,233 shares of common stock at a purchase price (without brokerage commissions) of $6.50 per share, for an aggregate purchase price of $394,300, excluding fees and expenses relating to the Offer. The 60,665,233 shares accepted for purchase in the Offer represented approximately 6.61% of the issued and outstanding shares of common stock at the time of purchase. Subsequent to the purchase of approved Offer shares, the final number of shares purchased, allowing for corrections, was 60,761,166 for a final aggregate purchase price of $394,900 as of December 31, 2014, excluding fees and expenses related to the Offer.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies
	In May 2012, the Company disclosed that the SEC is conducting a non-public, formal, fact-finding investigation ("SEC Investigation") to determine whether there have been violations of certain provisions of the federal securities laws regarding the payment of fees to the Company's former Business Manager and Property Managers, transactions with the Company's former affiliates, timing and amount of distributions paid to the Company's investors, determination of property impairments, and any decision regarding whether it might become a self-administered REIT.
	The Company subsequently received three related demands (“Derivative Demands”) by stockholders to conduct investigations regarding claims that the Company's officers, board of directors, former Business Manager, and affiliates of the Company's former Business Manager breached their fiduciary duties to the Company in connection with the matters that the Company disclosed were subject to the SEC Investigation.
	Upon receiving the first of the Derivative Demands, on October 16, 2012, the full board of directors responded by authorizing the independent directors to investigate the claims contained in the first Derivative Demand, any subsequent stockholder demands, as well as any other matters the independent directors saw fit to investigate. Pursuant to this authority, the independent directors formed a special litigation committee comprised solely of independent directors to review and evaluate the alleged claims and to recommend to the full board of directors whether the maintenance of a derivative proceeding was in the best interests of the Company. The special litigation committee engaged independent legal counsel and experts to assist in the investigation.
	On March 21, 2013, counsel for the stockholders who made the first Derivative Demand filed a derivative lawsuit in the Circuit Court of Cook County, Illinois, on behalf of the Company. The court stayed the case - Trumbo v. The Inland Group, Inc. -pending completion of the special litigation committee's investigation.
	On December 8, 2014, the special litigation committee completed its investigation and issued its report and recommendation. The special litigation committee concluded that there is no evidence to support the allegations of wrongdoing in the Derivative Demands. Nonetheless, in the course of its investigation, the special litigation committee uncovered facts indicating that certain then-related parties breached their fiduciary duties to the Company by failing to disclose to the independent directors certain facts and circumstances associated with the payment of fees to its former Business Manager and Property Managers. The special litigation committee determined that it is advisable and in the best interests of the Company to maintain a derivative action against its former Business Manager, Property Managers, and Inland American Holdco Management LLC. The special litigation committee found that it was not in the best interests of the Company to pursue claims against any other entities or against any individuals.
	On January 20, 2015, the board of directors adopted the report and recommendation of the special litigation committee in full and authorized the Company to file a motion to realign the Company as the party plaintiff in Trumbo v. The Inland Group, Inc., and to take such further actions as are necessary to reject and dismiss claims related to allegations that the board of directors has determined lack merit and to pursue claims against its former Business Manager, Property Managers, and Inland American Holdco Management LLC for breach of fiduciary duties in connection with the failure to disclose facts and circumstances associated with the payment of fees to related parties.
	On March 2, 2015, counsel for the stockholders who made the second Derivative Demand filed a derivative lawsuit in the Circuit Court of Cook County, Illinois, on behalf of the Company. The court entered an order consolidating the action with the Trumbo case on March 26, 2015.
	On March 24, 2015, the Staff of the SEC informed the Company that it had concluded its investigation and that, based on the information received to date, it did not intend to recommend any enforcement action against the Company.
	In connection with the Spin-Off of Xenia from the Company, the Company entered into an Indemnity Agreement with Xenia on August 8, 2014, as amended. Pursuant to the Indemnity Agreement, the Company agreed, to the fullest extent allowed by law or government regulation, to absolutely, irrevocably and unconditionally indemnify, defend and hold harmless Xenia and its subsidiaries, directors, officers, agents, representatives and employees (in each case, in such person’s respective capacity as such) and their respective heirs, executors, administrators, successors and assigns from and against all against losses, including but not limited to “actions” (as defined in the Indemnity Agreement), arising from: the SEC Investigation; the Derivative Demands; the Trumbo action; and the investigation by the special litigation committee of the board of directors of the Company, in each case, regardless of when or where the loss took place, or whether any such loss, claim, accident, occurrence, event or happening is known or unknown, and regardless of whether such loss, claim, accident, occurrence, event or happening giving rise to the loss existed prior to, on or after Xenia’s separation from the Company or relates to, arises out of or results from actions, inactions, events, omissions, conditions, facts or circumstances occurring or existing prior to, on or after Xenia’s separation from the Company.
	While, to the best of its knowledge, the Company does not presently anticipate Xenia or Xenia’s subsidiaries, directors, officers, agents, representatives and employees to be made a party to any actions related to the above matters, in connection with the separation of Xenia from the Company, the Company determined that it was in the best interests of the Company to enter into the Indemnity Agreement.
	The Company is subject, from time to time, to various legal proceedings and claims that arise in the ordinary course of business. While the resolution of these matters cannot be predicted with certainty, management believes, based on currently available information, that the final outcome of such matters will not have a material adverse effect on the financial statements of the Company.

In addition, the Company reimbursed the Property Managers approximately $249 for compensation and out-of-pocket expenses incurred between January 1, 2014 and March 12, 2014 for the Property Manager employees the Company hired at closing to approximate the economics as though the Company had hired such employees on January 1, 2014.

These service agreements are generally terminable without penalty by either party upon 60 days’ notice. These costs are reflected in general and administrative reimbursements above. During the year ended December 31, 2014, the Company sent termination notices for agreements with those affiliates of the Business Manager which provided information technology and investor services to the Company. During the three months ended March 31, 2015, the Company sent a termination notice for the agreement with those affiliates of the Business Manager which provided human resource services to the Company. The Business Manager and its related parties are entitled to reimbursement for general and administrative expenses of the Business Manager and its related parties relating to the Company's administration.
	Unpaid amounts of $411 as of December 31, 2014 are included in accounts payable and accrued expenses on the consolidated balance sheet.
	(b)	The Company paid a related party of the Business Manager to purchase and monitor its investment in marketable securities. The Company terminated this agreement during the three months ended March 31, 2015.
	(c)	As part of the Self-Management Transactions, select Property Management fees charged to the Company were reduced effective January 1, 2014 to reflect, among other things, the hiring of the Property Manager employees and the services that were no longer being performed by the Property Managers. The Amended Property Management Agreements reduced the property management fees charged in respect of most of the Company’s multi-tenant retail properties to 3.50% of gross income generated by the applicable property for the first six months of 2014, and reduced fees charged in respect of the Company’s multi-tenant office properties to 3.50% of gross income generated by the applicable property for the first six months of 2014.

	In addition to these fees, the Property Managers received reimbursements of payroll costs for property level employees. The Company reimbursed the Property Managers and other affiliates $2,391 for the three months ended March 31, 2014.
	(d)	In connection with the closing of the Master Modification Agreement and termination of the business management agreement, the Company paid a business management fee for January 2014, which totaled approximately $3,333. The Company did not pay a business management fee subsequent to January 31, 2014. Pursuant to the letter agreement dated May 4, 2012, the business management fee was reduced for investigation costs exclusive of legal fees incurred in conjunction with the SEC matter. The Master Modification Agreement contained a ninety-day reconciliation of certain payments and reimbursements, including the January 2014 business management fee. The reconciliation was completed during the three months ended June 30, 2014, which resulted in $739 of SEC-related investigation costs and an adjusted January 2014 business management fee expense of $2,594. Pursuant to the March 12, 2014 Self-Management Transactions, the May 4, 2012 letter agreement by the Business Manager has been terminated.
	(e)	The Company pays a related party of the Business Manager 0.2% of the principal amount of each loan placed for the Company. Such costs are capitalized as loan fees and amortized over the respective loan term.

[1]	On December 18, 2014, Cobalt sold all of its real estate assets, and the Company recognized its share of the gain on the sale of the assets in equity in earnings for the year ended December 31, 2014. The balance of this joint venture at March 31, 2015 reflects the Company's expected return of the joint venture's remaining cash assets
[2]	On February 4, 2013, the Company entered into a joint venture agreement with Gerding Edlen Investors, LLC ("GE") in order to develop, construct and manage a student housing community on the campus of the University of Oregon in Eugene, Oregon, which was completed later in 2013 and is now fully operational. The joint venture is known as 15th & Walnut Owner, LLC ("Eugene"). The Company contributed $5,200 for an equity stake of 62%. The Company analyzed the joint venture and determined it is a VIE because the entity did not have enough equity to finance its activities without additional subordinated financial support. The Company also considered its participating rights under the joint venture agreement and determined that such participating rights also required the agreement of GE, which equates to shared decision making ability, and therefore the Company did not have the power to direct the activities of the VIE that most significantly impacted the VIE's economic performance. As such, the Company has significant influence but does not control Eugene. Therefore, the Company does not consolidate this entity and accounts for its investment in the entity under the equity method of accounting.

[1]	In connection with the closing of the Master Modification Agreement and termination of the business management agreement on March 12, 2014, the Company reimbursed the Business Manager for compensation and other ordinary course out-of-pocket expenses, which totaled approximately $3,401. In addition, the Company reimbursed the Property Managers approximately $249 for compensation and out-of-pocket expenses incurred between January 1, 2014 and March 12, 2014 for the Property Manager employees the Company hired at closing to approximate the economics as though the Company had hired such employees on January 1, 2014. These costs are reflected in general and administrative reimbursements above. In addition, the Company has directly retained affiliates of the Business Manager to provide back-office services that were provided to the Company through the Business Manager prior to the termination of the business management agreement. These service agreements are generally terminable without penalty by either party upon 60 days’ notice. These costs are reflected in general and administrative reimbursements above.
