Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Organization	Basis of Presentation and Organization General Effective March 3, 2017, we changed our name from "Five Star Quality Care, Inc." to "Five Star Senior Living Inc." The accompanying condensed consolidated financial statements of Five Star Senior Living Inc. and its subsidiaries, or we, us or our, are unaudited. Certain information and disclosures required by U.S. generally accepted accounting principles, or GAAP, for complete financial statements have been condensed or omitted. We believe the disclosures made are adequate to make the information presented not misleading. However, the accompanying financial statements should be read in conjunction with the financial statements and notes contained in our Annual Report on Form 10-K for the year ended December 31, 2016 , or our Annual Report. In the opinion of our management, all adjustments, which include only normal recurring adjustments, considered necessary for a fair presentation have been included. All intercompany transactions and balances with or among our consolidated subsidiaries have been eliminated. Our operating results for interim periods are not necessarily indicative of the results that may be expected for the full year. Certain reclassifications have been made to the prior years’ condensed consolidated financial statements to conform to the current year’s presentation. We operate senior living communities, including independent living communities, assisted living communities and skilled nursing facilities, or SNFs. As of June 30, 2017 , we operated 283 senior living communities located in 32 states with 31,820 living units, including 253 primarily independent and assisted living communities with 29,218 living units and 30 SNFs with 2,602 living units. As of June 30, 2017 , we owned and operated 26 communities ( 2,703 living units), we leased and operated 189 communities ( 20,311 living units) and we managed 68 communities ( 8,806 living units). Our 283 senior living communities, as of June 30, 2017 , included 10,773 independent living apartments, 16,167 assisted living suites and 4,880 skilled nursing beds. The foregoing numbers exclude living units categorized as out of service. Segment Information We have two operating segments: (i) senior living communities and (ii) rehabilitation and wellness. In the senior living communities segment, we operate for our own account or manage for the account of others independent living communities, assisted living communities and SNFs that are subject to centralized oversight and provide housing and services to elderly residents. In the rehabilitation and wellness operating segment, we provide services in the inpatient setting and in outpatient clinics. We have determined that our two operating segments meet the aggregation criteria as prescribed under Financial Accounting Standards Board, or FASB, Accounting Standards Codification TM , or ASC, Topic 280, Segment Reporting , and we have therefore determined that our business is comprised of one reportable segment, senior living. All of our operations and assets are located in the United States, except for the operations of our Cayman Islands organized captive insurance company subsidiary, which participates in our workers’ compensation and professional and general liability insurance programs.

Recent Accounting Pronouncement

Recent Accounting Pronouncements	6 Months Ended

Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements On January 1, 2017, we adopted FASB Accounting Standards Update, or ASU, No. 2016-09, Compensation-Stock Compensation (Topic 718) , which identifies areas for simplification involving several aspects of accounting for share based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. This ASU requires prospective recognition of excess tax benefits and deficiencies resulting from share based compensation award vesting and exercises be recognized in our consolidated statements of operations. Previously, these amounts were recognized in additional paid in capital, and were not material to our consolidated financial statements. Excess tax benefits from share based compensation awards will continue to be reported as an operating activity, and cash paid on employees’ behalf related to shares withheld for tax purposes will continue to be classified as a financing activity, in the statement of cash flows. In addition, forfeitures will be recognized as they occur as permitted by this ASU. The implementation of this ASU did not have a material impact on our consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, which changes how entities measure certain equity investments and present changes in the fair value of financial liabilities measured under the fair value option that are attributable to their own credit. This ASU is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted subject to certain conditions. Currently, changes in fair value of these investments are recorded through other comprehensive income. Under this ASU, these changes will be recorded through earnings. We are currently assessing this ASU, but we expect the implementation of this ASU will affect how we record changes in fair value of the available for sale securities that we hold. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). ASU No. 2016-02 requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease. A lessee is also required to record a right of use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. This ASU requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales type leases, direct financing leases and operating leases. ASU No. 2016-02 is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. While we are continuing to assess the impact adopting this ASU may have on our consolidated financial statements, we believe the adoption of this ASU will have a material impact on our consolidated balance sheets due to the recognition of the lease rights and obligations as assets and liabilities. While the adoption will have no effect on the cash rent we pay, we expect amounts within our statements of operations and comprehensive (loss) income to change materially. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) , which outlines a comprehensive model for entities to use in accounting for revenue arising from contracts with customers. This ASU clarifies the principles for recognizing revenue by, among other things, removing inconsistencies in revenue requirements, improving comparability of revenue recognition practices across entities and industries and providing improved disclosure requirements. In July 2015, the FASB approved a one year deferral of the effective date for this ASU to interim and annual reporting periods beginning after December 15, 2017, with early adoption permitted. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which clarifies how an entity should identify the unit of accounting for the principal versus agent evaluation and how it should apply the control principle to certain types of arrangements, such as service transactions. These ASUs may be applied retrospectively to each prior period (full retrospective) or retrospectively with the cumulative effect recognized as of the date of initial application (modified retrospective). We will adopt these ASUs as required effective January 1, 2018 and currently expect to apply the modified retrospective approach. While we are continuing to assess the impact adopting these ASUs (and related clarifying guidance issued by the FASB) will have on our consolidated financial statements, we believe its adoption will not have a material impact on the timing of our revenue recognition. We do expect the adoption will result in expanded disclosures related to the nature, amount, timing and uncertainty of revenue and cash flows arising from our contracts with customers that are included in the scope of these ASUs. A substantial portion of our revenue relates to contracts with residents that are generally short term in nature and fall under ASC Topic 840, Leases , which are specifically excluded from the scope of ASU No. 2014-09. Our contracts with residents and other customers that are included in the scope of these ASUs are also generally short term in nature and revenue is recognized when services are provided. As we complete our evaluation of these ASUs, new information may arise that could change our current understanding of the impact to revenue recognized. Additionally, we will continue to monitor industry activities and any additional guidance provided by regulators, standards setters and the accounting profession and will adjust our assessment and implementation plans accordingly. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326) , which requires a financial asset or a group of financial assets measured at amortized cost basis, to be presented at the net amount expected to be collected. This ASU eliminates the probable initial recognition threshold and instead reflects an entity’s current estimate of all expected credit losses. In addition, this ASU amends the current available for sale security other-than-temporary impairment model for debt securities. The length of time that the fair value of an available for sale debt security has been below the amortized cost will no longer impact the determination of whether a credit loss exists and credit losses will now be limited to the difference between a security’s amortized cost basis and its fair value. This ASU is effective for reporting periods beginning after December 15, 2019. We are currently assessing the potential impact the adoption of this ASU will have on our consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments , which clarifies how companies present and classify certain cash receipts and cash payments in the statement of cash flows. ASU No. 2016-15 is effective for reporting periods beginning after December 15, 2017. We are currently assessing the potential impact the adoption of this ASU will have on our consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash , which requires that the reconciliation of the beginning-of-period and end-of-period amounts shown in the statement of cash flows include restricted cash and restricted cash equivalents. In the event restricted cash is presented separately from cash and cash equivalents on the balance sheet, companies will be required to reconcile the amounts presented on the statement of cash flows to the amounts on the balance sheet and disclose information about the nature of the restrictions. ASU No. 2016-18 is effective for reporting periods beginning after December 15, 2017. Upon the adoption of ASU No. 2016-18, we will reconcile both cash and cash equivalents and restricted cash and restricted cash equivalents, whereas under the current guidance we explain the changes during the period for cash and cash equivalents only. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805) , which clarifies the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or of businesses. The amendments in this ASU provide a screen to determine when an acquired set of activities is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the assets are not a business. This ASU is effective for reporting periods beginning after December 15, 2017, with early adoption permitted. We are currently assessing the impact adopting this ASU will have on our consolidated financial statements, but we expect that most future acquisitions, if completed with terms similar to historical transactions, will be treated as acquisitions of assets rather than as business combinations, as substantially all of the fair value of the assets we typically acquire is concentrated in real estate. In an acquisition of assets, certain acquisition costs are capitalized as opposed to expensed under business combination guidance. In March 2017, the FASB issued ASU No. 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20) , which shortens the amortization period for certain callable debt securities held at a premium. Specifically, this ASU requires the premium to be amortized to the earliest call date. This ASU does not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. This ASU is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. We are currently assessing the potential impact the adoption of this ASU will have on our consolidated financial statements. In May 2017, the FASB issued ASU No. 2017-09, Compensation-Stock Compensation (Topic 718) , which provides additional guidance on which changes to the terms and conditions of a share-based payment award require an entity to apply modification accounting. This ASU is effective for reporting periods beginning after December 15, 2017. We are continuing to evaluate ASU No. 2017-09; however, we do not expect its adoption to have a material impact in our condensed consolidated financial statements.

We review the carrying value of long lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If there is an indication that the carrying value of an asset is not recoverable, we determine the amount of impairment loss, if any, by comparing the historical carrying value of the asset to its estimated fair value. We determine estimated fair value based on input from market participants, our experience selling similar assets, market conditions and internally developed cash flow models that our assets or asset groups are expected to generate, and we consider these estimates to be a Level 3 fair value measurement. As a result of our long lived assets impairment review, we recorded $176 and $0 of impairment charges to certain of our long lived assets in continuing operations for the three months ended June 30, 2017 and 2016 , respectively, and $386 and $306 for the six months ended June 30, 2017 and 2016 , respectively. As of June 30, 2017 , we had $3,215 of assets related to our leased senior living communities included in our property and equipment that we expect to request Senior Housing Properties Trust, or, together with its subsidiaries, SNH, to purchase from us for an increase in future rent; however, SNH is not obligated to purchase such amounts.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We recognized a benefit for income taxes from continuing operations of $1,366 and $1,275 for the three and six months ended June 30, 2017, respectively. We recognized a provision for income taxes from continuing operations of $3,486 and $3,775 for the three and six months ended June 30, 2016, respectively. The benefit for income taxes for the three and six months ended June 30, 2017 is due primarily to monetizing alternative minimum tax credits in the second quarter of 2017. The provision for income taxes for the three and six months ended June 30, 2016 is due primarily to the sale and leaseback transaction with SNH in June 2016. We did not recognize any income tax expense or benefit from our discontinued operations in the three or six months ended June 30, 2017 or 2016. We previously determined it was more likely than not that our net deferred tax assets would not be realized and concluded that a full valuation allowance was required, which eliminated the amount of our net deferred tax assets recorded in our consolidated balance sheets. In the future, if we believe that we will more likely than not realize the benefit of these deferred tax assets, we will adjust our valuation allowance and recognize an income tax benefit, which may affect our results of operations.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share We calculated basic earnings per common share, or EPS, for the three and six months ended June 30, 2017 and 2016 using the weighted average number of shares of our common stock, $.01 par value per share, or our common shares, outstanding during the periods. When applicable, diluted EPS reflects the more dilutive earnings per common share amount calculated using the two class method or the treasury stock method. The three months ended June 30, 2017 and 2016 had 1,097,605 and 930,605 , respectively, and the six months ended June 30, 2017 and 2016 had 1,021,037 and 936,424 , respectively, of potentially dilutive restricted unvested common shares that were not included in the calculation of diluted EPS because to do so would have been antidilutive.

Fair Value Disclosures [Abstract]
Fair Values of Assets and Liabilities	Fair Values of Assets and Liabilities Our assets recorded at fair value have been categorized based upon a fair value hierarchy in accordance with FASB ASC Topic 820, Fair Value Measurements and Disclosures . We apply the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets and quoted prices in inactive markets. Level 3 inputs are unobservable inputs for the asset or liability in which there is little, if any, market activity for the asset or liability at the measurement date. Recurring Fair Value Measures The tables below present the assets measured at fair value at June 30, 2017 and December 31, 2016 categorized by the level of inputs used in the valuation of each asset.

Cash equivalents are reported in our condensed consolidated balance sheets as cash and cash equivalents and current and long term restricted cash. Cash equivalents include $ 19,087 and $ 14,638 of balances that are restricted at June 30, 2017 and December 31, 2016 , respectively. (2) As of June 30, 2017 , our investments in available for sale securities had a fair value of $ 37,693 with an amortized cost of $ 35,384 ; the difference between the fair value and amortized cost amounts resulted from unrealized gains of $ 2,452 , net of unrealized losses of $ 144 . As of December 31, 2016 , our investments in available for sale securities had a fair value of $ 40,670 with an amortized cost of $ 38,537 ; the difference between the fair value and amortized cost amounts resulted from unrealized gains of $ 2,430 , net of unrealized losses of $ 297 . At June 30, 2017 , 37 of the securities we hold, with a fair value of $ 11,189 , have been in a loss position for less than 12 months and four of the securities we hold, with a fair value of $ 390 , have been in a loss position for greater than 12 months . We do not believe these securities are impaired primarily because they have not been in a loss position for an extended period of time, the financial conditions of the issuers of these securities remain strong with solid fundamentals, or we intend to hold these securities until recovery, and other factors that support our conclusion that the loss is temporary. During the six months ended June 30, 2017 and 2016 , we received gross proceeds of $ 12,791 and $ 8,685 , respectively, in connection with the sales of available for sale securities and recorded gross realized gains totaling $ 452 and $ 375 , respectively, and gross realized losses totaling $ 171 and $ 140 , respectively. We record gains and losses on the sales of our available for sale securities using the specific identification method. (3) The investment strategy of this fund is to invest principally in fixed income securities issued by non-U.S. issuers. The fund invests in such securities or investment vehicles as it considers appropriate to achieve the fund’s investment objective, which is to provide an above average rate of total return while attempting to limit investment risk by investing in a diversified portfolio of U.S. dollar investment grade fixed income securities. There are no unfunded commitments and the investment can be redeemed weekly. (4) The investment strategy of this fund is to invest principally in fixed income securities. The fund invests in such securities or investment vehicles as it considers appropriate to achieve the fund’s investment objective, which is to provide an above average rate of total return while attempting to limit investment risk by investing in a diversified portfolio of primarily fixed income securities issued by companies with below investment grade ratings. There are no unfunded commitments and the investment can be redeemed weekly. During the six months ended June 30, 2017 , we did not change the type of inputs used to determine the fair value of any of our assets and liabilities that we measure at fair value. Accordingly, there were no transfers of assets or liabilities between levels of the fair value hierarchy during the six months ended June 30, 2017 . The carrying values of accounts receivable and accounts payable approximate fair value as of June 30, 2017 and December 31, 2016 . The carrying value and fair value of our mortgage notes payable were $ 59,457 and $ 63,947 , respectively, as of June 30, 2017 and $ 60,397 and $ 64,905 , respectively, as of December 31, 2016 , and are categorized in Level 3 of the fair value hierarchy in their entirety. We estimate the fair values of our mortgage notes payable by using discounted cash flow analyses and currently prevailing market terms as of the measurement date. Non-Recurring Fair Value Measures We review the carrying value of our long lived assets, including our property and equipment and other intangible assets for impairment whenever events or changes in circumstances indicate that the carrying value of an asset or asset group may not be recoverable. See Note 3 for further information regarding fair value measurements related to impairments of our long lived assets we recorded in continuing operations. The fair value of assets held for sale is determined based on the use of appraisals, input from market participants, our experience selling similar assets and/or internally developed cash flow models, all of which are considered to be Level 3 fair value measurements. We recorded long lived asset impairment charges of $325 for the three months ended March 31, 2016 to reduce the carrying value of an assisted living community we classified as held for sale and in discontinued operations to its estimated fair value, less costs to sell. During the three months ended June 30, 2016, in accordance with FASB ASC 360, Property, Plant and Equipment , we recorded a gain of $213 to increase the carrying value of this community based on an increase in its estimated fair value, less costs to sell.

Debt Disclosure [Abstract]
Indebtedness	Indebtedness We previously had a $100,000 secured revolving credit facility, or our prior credit facility, which was scheduled to mature in April 2017. In February 2017, we replaced our prior credit facility with a new $100,000 secured revolving credit facility, or our credit facility, with terms substantially similar to those of our prior credit facility. We paid fees of $1,898 in connection with the closing of our credit facility, which fees were deferred and will be amortized over the initial term of our credit facility. Our credit facility is available for general business purposes, including acquisitions, provides for issuance of letters of credit and matures in February 2020. Subject to our payment of extension fees and meeting other conditions, we have options to extend the stated maturity date of our credit facility for two , one year periods. We are required to pay interest at an annual rate of LIBOR plus a premium of 250 basis points, or 3.56% as of June 30, 2017 , on outstanding borrowings under our credit facility. We are also required to pay a quarterly commitment fee of 0.35% per annum on the unused part of the available borrowings under our credit facility. We can borrow, repay and re-borrow funds available until maturity, and no principal repayment is due until maturity. The weighted average annual interest rate for borrowings under our credit facility was 5.44% for the six months ended June 30, 2017 . We had no borrowings outstanding under our prior credit facility during the six months ended June 30, 2017. As of June 30, 2017 , we had letters of credit issued under our credit facility in an aggregate amount of $545 and $99,455 available for borrowing under our credit facility. We incurred aggregate interest expense and other associated costs related to our credit facilities of $305 and $ 695 for the three months ended June 30, 2017 and 2016 , respectively, and $490 and $1,332 for the six months ended June 30, 2017 and 2016 , respectively. Certain of our subsidiaries guarantee our obligations under our credit facility, which is secured by real estate mortgages on 10 senior living communities with a combined 1,219 living units owned by our guarantor subsidiaries and our guarantor subsidiaries’ accounts receivable and related collateral. The amount of available borrowings under our credit facility is subject to our having qualified collateral, which is primarily based on the value of the communities securing our obligations under our credit facility. Accordingly, the maximum availability of borrowings under our credit facility at any time may be less than $100,000 . Our credit facility provides for acceleration of payment of all amounts outstanding under our credit facility upon the occurrence and continuation of certain events of default, including a change of control of us, as defined. The agreement that governs our credit facility contains a number of financial and other covenants, including covenants that restrict our ability to incur indebtedness or to pay dividends or make other distributions under certain circumstances, and requires us to maintain financial ratios and a minimum net worth. We also previously had a $ 25,000 secured revolving line of credit that matured on March 18, 2016, that we did not extend or replace. We had no borrowings outstanding under this line of credit during the six months ended June 30, 2016 . We incurred associated costs of $ 0 and $ 45 related to this line of credit for the three and six months ended June 30, 2016 , respectively. In June 2017, we increased our so-called “step up” letter of credit, which is used as security for our workers’ compensation insurance program and is collateralized by approximately $16,730 in cash equivalents and $2,615 in debt securities, from $11,700 to $17,800 . This letter of credit matures in June 2018. We are required to increase the cash collateral under this letter of credit quarterly so that the stated amount of $17,800 is met by March 2018. At June 30, 2017, the cash collateral is classified as short term restricted cash, which amount includes accumulated interest, and the debt securities collateral is classified as short term investments in available for sale securities, in our condensed consolidated balance sheet. At June 30, 2017, we had six other irrevocable standby letters of credit outstanding, totaling $1,209 , which secure certain of our other obligations. These letters of credit currently mature between September 2017 and May 2018 but are renewed annually. Our obligations under these letters of credit either are secured by cash or cash equivalents or issued under our credit facility. At June 30, 2017 , six of our senior living communities were encumbered by mortgages with a carrying value of $ 59,457 : (i) two of our communities were encumbered by Federal National Mortgage Association, or FNMA, mortgages; (ii) two of our communities were encumbered by Federal Home Loan Mortgage Corporation, or FMCC, mortgages; and (iii) two of our communities were encumbered by a mortgage from a commercial lender. These mortgages contain standard mortgage covenants. We recorded mortgage discounts or premiums in connection with the assumption of certain of these mortgage debts as part of our acquisitions of the encumbered communities in order to record the assumed mortgage debts at their respective estimated fair value. We are amortizing the mortgage discounts or premiums as an increase or reduction of interest expense until the maturity of the respective mortgage debt. The weighted average annual interest rate on these mortgage debts was 6.26% as of June 30, 2017 . Payments of principal and interest are due monthly under these mortgage debts until their respective maturities at varying dates ranging from June 2018 to September 2032. We incurred mortgage interest expense, net of discount or premium amortization, of $ 778 and $ 802 for the three months ended June 30, 2017 and 2016 , respectively, and $ 1,571 and $ 1,619 for the six months ended June 30, 2017 and 2016 , respectively. Our mortgage debts require monthly payments into escrows for taxes, insurance and property replacement funds; certain withdrawals from escrows for our FNMA and FMCC mortgages require applicable FNMA and FMCC approval. As of June 30, 2017 , we believe we were in compliance with all applicable covenants under our credit facility and mortgage debts.

Transfers and Servicing [Abstract]
Off Balance Sheet Arrangements	Off Balance Sheet Arrangements Certain of our assets, related to our operation of 17 communities we lease from SNH, were pledged as collateral for SNH’s borrowings from its lender, FNMA. On April 28, 2017, SNH prepaid those borrowings and, as a result, our assets are no longer pledged as collateral. As of June 30, 2017 , we had no off balance sheet arrangements that have had or that we expect would be reasonably likely to have a future material effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

Leases [Abstract]
Leases and Management Agreements with SNH	Leases and Management Agreements with SNH Senior Living Communities Leased from SNH . We are SNH’s largest tenant and SNH is our largest landlord. As of June 30, 2017 and 2016 , we leased 185 and 184 senior living communities from SNH, respectively. We lease senior living communities from SNH pursuant to five leases with SNH. Our total annual rent payable to SNH as of June 30, 2017 and 2016 was $205,370 and $ 201,672 , respectively, excluding percentage rent based on increases in gross revenues at certain communities. Our total rent expense under all of our leases with SNH, net of lease inducement amortization and the amortization of the deferred gain associated with the sale and leaseback transaction with SNH in June 2016 described below, was $50,792 and $49,396 for the three months ended June 30, 2017 and 2016 , respectively, and $101,302 and $98,770 for the six months ended June 30, 2017 and 2016 , respectively, which amounts included estimated percentage rent of $1,391 and $1,387 for the three months ended June 30, 2017 and 2016 , respectively, and $2,835 and $2,855 for the six months ended June 30, 2017 and 2016 , respectively. As of June 30, 2017 and December 31, 2016, we had outstanding rent due and payable to SNH of $18,436 and $18,338 , respectively, which are included in due to related persons in our condensed consolidated balance sheets. Pursuant to the terms of our leases with SNH, for the six months ended June 30, 2017 and 2016 , we sold to SNH $19,308 and $ 11,710 , respectively, of improvements to communities leased from SNH. As a result, the annual rent payable by us to SNH increased by approximately $1,547 and $ 940 for the six months ended June 30, 2017 and 2016 , respectively. As of June 30, 2017 , our property and equipment included $3,215 for similar improvements to communities leased from SNH that we expect to request SNH to purchase from us for an increase in future rent; however, SNH is not obligated to purchase these improvements. During the quarter ended June 30, 2017, we and SNH agreed to amend the applicable lease for certain construction, expansion and development projects at two senior living communities we lease from SNH. If and when we request SNH to purchase improvements related to these specific projects from us, our annual rent payable to SNH will increase by an amount equal to the interest rate then applicable to SNH’s borrowings under its revolving credit facility plus 2% per annum of the amount SNH purchased. This amount of increased rent will apply until 12 months after a certificate of occupancy is issued with respect to the project; thereafter, our annual rent payable to SNH will be revised to equal the amount determined pursuant to the capital improvement formula specified in the applicable lease. In June 2016, we entered into an agreement with SNH pursuant to which, on June 29, 2016, we sold seven senior living communities to SNH for an aggregate purchase price of $112,350 and SNH simultaneously leased these communities back to us under a new long term lease agreement. Under the new lease, we are required to pay SNH initial annual rent of $8,426 , plus percentage rent beginning in 2018. In accordance with FASB ASC Topic 840, Leases , the June 2016 sale and leaseback transaction qualifies for sale-leaseback accounting. Accordingly, the gain generated from the sale of $82,644 was deferred and is being amortized as a reduction of rent expense over the initial term of the lease. As of June 30, 2017 and December 31, 2016, the short term part of the deferred gain of $6,609 is included in other current liabilities and the long term part of the deferred gain is included separately in our condensed consolidated balance sheets. We incurred transaction costs of $750 in connection with the sale of the senior living communities to SNH, which amount was expensed in full during the three months ended June 30, 2016. Senior Living Communities Managed for the Account of SNH and its Related Entities . As of June 30, 2017 and 2016 , we managed 68 and 62 senior living communities, respectively, for the account of SNH. We earned management fees of $3,172 and $2,749 from the senior living communities we managed for the account of SNH for the three months ended June 30, 2017 and 2016 , respectively, and $6,359 and $5,490 for the six months ended June 30, 2017 and 2016 , respectively. In addition, we earned fees for our supervision of capital expenditure projects at the communities we managed for the account of SNH of $236 and $500 for the three and six months ended June 30, 2017 , respectively, which amount is included in management fee revenue in our condensed consolidated statement of operations. During the quarter ended June 30, 2017 , we and SNH agreed to amend the applicable management and pooling agreements for a construction, expansion and development project at a senior living community that SNH owns and we manage. SNH’s annual minimum return of invested capital for this specific project will increase by an amount equal to the interest rate then applicable to its borrowings under its revolving credit facility plus 2% per annum. This amount of increased minimum return will apply until 12 months after a certificate of occupancy is issued with respect to the project; thereafter, the amount of annual minimum return of invested capital will be revised to equal the amount determined pursuant to the applicable management and pooling agreements. We and SNH also agreed that the commencement of the measurement period for determining whether the specified annual minimum return under the applicable management and pooling agreements has been achieved will be deferred until 12 months after a certificate of occupancy is issued with respect to the project. Simultaneously with the June 2016 sale and leaseback transaction, we and SNH terminated three of our four then existing pooling agreements and entered into 10 new pooling agreements that combine our management agreements with SNH for senior living communities that include assisted living units. Pursuant to these management agreements and the new pooling agreements, we receive from SNH management fees equal to either 3% or 5% of the gross revenues realized at the applicable communities, reimbursement for our direct costs and expenses related to such communities, annual incentive fees if certain operating results at those communities are achieved and fees for our supervision of capital expenditure projects at those communities equal to 3% of amounts funded by SNH. Under these new pooling agreements, the calculations of our fees and of SNH’s annual minimum return related to management agreements that include assisted living units that became effective before May 2015 and had been pooled under one of the previously existing pooling agreements are generally the same as they were under the previously existing pooling agreements. However, for certain communities, the new pooling agreements reduced the annual minimum returns that must be realized by SNH before we earn incentive fees and also, with respect to 10 communities, reset such annual minimum returns to specified amounts. For those management agreements that include assisted living units that became effective from and after May 2015, these new pooling agreements increased our management fees from 3% to 5% of the gross revenues realized at the applicable communities, and changed our annual incentive fees from 35% to 20% of the annual net operating income of the applicable communities remaining after SNH realizes the requisite annual minimum returns. In order to accommodate certain requirements of New York healthcare licensing laws, a part of the senior living community SNH owns, and we manage, located in Yonkers, New York is subleased by a subsidiary of SNH to D&R Yonkers LLC. D&R Yonkers LLC is owned by our Chief Financial Officer and Treasurer and by SNH’s president and chief operating officer. We count the part of this community that we manage for D&R Yonkers LLC and the part of this senior living community we manage for SNH as one senior living community. We earned management fees of $146 and $66 for the three months ended June 30, 2017 and 2016 , respectively, and $258 and $129 for the six months ended June 30, 2017 and 2016 , respectively, under this management arrangement with D&R Yonkers LLC. These amounts are in addition to the management fees we earn and report for the senior living communities we manage for the account of SNH and are included in management fee revenue in our condensed consolidated statements of operations.

Commitments and Contingencies Disclosure [Abstract]
Legal Proceedings and Claims	Legal Proceedings and Claims We have been, are currently, and expect in the future to be involved in claims, lawsuits, and regulatory and other government audits, investigations and proceedings arising in the ordinary course of our business, some of which may involve material amounts. Also, the defense and resolution of these claims, lawsuits, and regulatory and other government audits, investigations and proceedings may require us to incur significant expense. We account for claims and litigation losses in accordance with FASB ASC Topic 450, Contingencies , or ASC 450. Under ASC 450, loss contingency provisions are recorded for probable and estimable losses at our best estimate of a loss or, when a best estimate cannot be made, at our estimate of the minimum loss. These estimates are often developed prior to knowing the amount of the ultimate loss, require the application of considerable judgment and are refined as additional information becomes known. Accordingly, we are often initially unable to develop a best estimate of loss and therefore the estimated minimum loss amount, which could be zero , is recorded; then, as information becomes known, the minimum loss amount is updated, as appropriate. Minimum or best estimate amounts may be increased or decreased when events result in changed expectations. As previously disclosed, as a result of our compliance program to review medical records related to our Medicare billing practices, during 2014 we discovered potentially inadequate documentation and other issues at one of our leased SNFs. This compliance review was not initiated in response to any specific complaint or allegation, but was a review of the type that we periodically undertake to test our own compliance with applicable Medicare billing rules. As a result of these discoveries, in February 2015, we made a voluntary disclosure of deficiencies to the United States Department of Health and Human Services Office of the Inspector General, or the OIG, pursuant to the OIG’s Provider Self-Disclosure Protocol. We completed our investigation and assessment of these matters and submitted a final supplemental disclosure to the OIG in May 2015. In June 2016, we settled this matter with the OIG and agreed to pay approximately $8,600 in exchange for a customary release but did not admit any liability. We previously accrued a total liability of $10,100 related to this matter, all of which was accrued at December 31, 2015. As a result of the accrued liability exceeding the final settlement amount, we recorded an increase to earnings in our results of operations for the three months ended June 30, 2016 of approximately $1,500 . Of the total increase to earnings, $1,000 was recorded as an increase to senior living revenue and $500 as a decrease to other senior living operating expenses in our condensed consolidated statements of operations consistent with the classification of the original charges. We were defendants in a lawsuit filed in the Superior Court of Maricopa County, Arizona by the estate of a former resident of a senior living community operated by us. The complaint asserted claims against us for pain and suffering as a result of improper treatment constituting violations of the Arizona Adult Protective Services Act and wrongful death. In May 2015, the jury rendered a decision in our favor on the wrongful death claim, and against us on the remaining claims, returning verdicts awarding damages of approximately $19,200 , which consisted of $2,500 for pain and suffering and the remainder in punitive damages. In March 2016, pursuant to a settlement agreement we entered into with the plaintiff, $7,250 was paid to the plaintiff, of which $3,021 was paid by our then liability insurer and the balance by us. We recorded a $4,229 charge for the year ended December 31, 2015 for the net settlement amount we paid. We believe our former liability insurer is financially responsible for more than $3,021 , and we have commenced litigation in the Superior Court of Middlesex County, Massachusetts seeking additional payments from our former liability insurer. We cannot predict the outcome of the litigation with our former liability insurer.

Accounting Policies [Abstract]
Recent Accounting Pronouncements	On January 1, 2017, we adopted FASB Accounting Standards Update, or ASU, No. 2016-09, Compensation-Stock Compensation (Topic 718) , which identifies areas for simplification involving several aspects of accounting for share based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. This ASU requires prospective recognition of excess tax benefits and deficiencies resulting from share based compensation award vesting and exercises be recognized in our consolidated statements of operations. Previously, these amounts were recognized in additional paid in capital, and were not material to our consolidated financial statements. Excess tax benefits from share based compensation awards will continue to be reported as an operating activity, and cash paid on employees’ behalf related to shares withheld for tax purposes will continue to be classified as a financing activity, in the statement of cash flows. In addition, forfeitures will be recognized as they occur as permitted by this ASU. The implementation of this ASU did not have a material impact on our consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, which changes how entities measure certain equity investments and present changes in the fair value of financial liabilities measured under the fair value option that are attributable to their own credit. This ASU is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted subject to certain conditions. Currently, changes in fair value of these investments are recorded through other comprehensive income. Under this ASU, these changes will be recorded through earnings. We are currently assessing this ASU, but we expect the implementation of this ASU will affect how we record changes in fair value of the available for sale securities that we hold. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). ASU No. 2016-02 requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease. A lessee is also required to record a right of use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. This ASU requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales type leases, direct financing leases and operating leases. ASU No. 2016-02 is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. While we are continuing to assess the impact adopting this ASU may have on our consolidated financial statements, we believe the adoption of this ASU will have a material impact on our consolidated balance sheets due to the recognition of the lease rights and obligations as assets and liabilities. While the adoption will have no effect on the cash rent we pay, we expect amounts within our statements of operations and comprehensive (loss) income to change materially. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) , which outlines a comprehensive model for entities to use in accounting for revenue arising from contracts with customers. This ASU clarifies the principles for recognizing revenue by, among other things, removing inconsistencies in revenue requirements, improving comparability of revenue recognition practices across entities and industries and providing improved disclosure requirements. In July 2015, the FASB approved a one year deferral of the effective date for this ASU to interim and annual reporting periods beginning after December 15, 2017, with early adoption permitted. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which clarifies how an entity should identify the unit of accounting for the principal versus agent evaluation and how it should apply the control principle to certain types of arrangements, such as service transactions. These ASUs may be applied retrospectively to each prior period (full retrospective) or retrospectively with the cumulative effect recognized as of the date of initial application (modified retrospective). We will adopt these ASUs as required effective January 1, 2018 and currently expect to apply the modified retrospective approach. While we are continuing to assess the impact adopting these ASUs (and related clarifying guidance issued by the FASB) will have on our consolidated financial statements, we believe its adoption will not have a material impact on the timing of our revenue recognition. We do expect the adoption will result in expanded disclosures related to the nature, amount, timing and uncertainty of revenue and cash flows arising from our contracts with customers that are included in the scope of these ASUs. A substantial portion of our revenue relates to contracts with residents that are generally short term in nature and fall under ASC Topic 840, Leases , which are specifically excluded from the scope of ASU No. 2014-09. Our contracts with residents and other customers that are included in the scope of these ASUs are also generally short term in nature and revenue is recognized when services are provided. As we complete our evaluation of these ASUs, new information may arise that could change our current understanding of the impact to revenue recognized. Additionally, we will continue to monitor industry activities and any additional guidance provided by regulators, standards setters and the accounting profession and will adjust our assessment and implementation plans accordingly. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326) , which requires a financial asset or a group of financial assets measured at amortized cost basis, to be presented at the net amount expected to be collected. This ASU eliminates the probable initial recognition threshold and instead reflects an entity’s current estimate of all expected credit losses. In addition, this ASU amends the current available for sale security other-than-temporary impairment model for debt securities. The length of time that the fair value of an available for sale debt security has been below the amortized cost will no longer impact the determination of whether a credit loss exists and credit losses will now be limited to the difference between a security’s amortized cost basis and its fair value. This ASU is effective for reporting periods beginning after December 15, 2019. We are currently assessing the potential impact the adoption of this ASU will have on our consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments , which clarifies how companies present and classify certain cash receipts and cash payments in the statement of cash flows. ASU No. 2016-15 is effective for reporting periods beginning after December 15, 2017. We are currently assessing the potential impact the adoption of this ASU will have on our consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash , which requires that the reconciliation of the beginning-of-period and end-of-period amounts shown in the statement of cash flows include restricted cash and restricted cash equivalents. In the event restricted cash is presented separately from cash and cash equivalents on the balance sheet, companies will be required to reconcile the amounts presented on the statement of cash flows to the amounts on the balance sheet and disclose information about the nature of the restrictions. ASU No. 2016-18 is effective for reporting periods beginning after December 15, 2017. Upon the adoption of ASU No. 2016-18, we will reconcile both cash and cash equivalents and restricted cash and restricted cash equivalents, whereas under the current guidance we explain the changes during the period for cash and cash equivalents only. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805) , which clarifies the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or of businesses. The amendments in this ASU provide a screen to determine when an acquired set of activities is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the assets are not a business. This ASU is effective for reporting periods beginning after December 15, 2017, with early adoption permitted. We are currently assessing the impact adopting this ASU will have on our consolidated financial statements, but we expect that most future acquisitions, if completed with terms similar to historical transactions, will be treated as acquisitions of assets rather than as business combinations, as substantially all of the fair value of the assets we typically acquire is concentrated in real estate. In an acquisition of assets, certain acquisition costs are capitalized as opposed to expensed under business combination guidance. In March 2017, the FASB issued ASU No. 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20) , which shortens the amortization period for certain callable debt securities held at a premium. Specifically, this ASU requires the premium to be amortized to the earliest call date. This ASU does not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. This ASU is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. We are currently assessing the potential impact the adoption of this ASU will have on our consolidated financial statements. In May 2017, the FASB issued ASU No. 2017-09, Compensation-Stock Compensation (Topic 718) , which provides additional guidance on which changes to the terms and conditions of a share-based payment award require an entity to apply modification accounting. This ASU is effective for reporting periods beginning after December 15, 2017. We are continuing to evaluate ASU No. 2017-09; however, we do not expect its adoption to have a material impact in our condensed consolidated financial statements.

Cash equivalents are reported in our condensed consolidated balance sheets as cash and cash equivalents and current and long term restricted cash. Cash equivalents include $ 19,087 and $ 14,638 of balances that are restricted at June 30, 2017 and December 31, 2016 , respectively. (2) As of June 30, 2017 , our investments in available for sale securities had a fair value of $ 37,693 with an amortized cost of $ 35,384 ; the difference between the fair value and amortized cost amounts resulted from unrealized gains of $ 2,452 , net of unrealized losses of $ 144 . As of December 31, 2016 , our investments in available for sale securities had a fair value of $ 40,670 with an amortized cost of $ 38,537 ; the difference between the fair value and amortized cost amounts resulted from unrealized gains of $ 2,430 , net of unrealized losses of $ 297 . At June 30, 2017 , 37 of the securities we hold, with a fair value of $ 11,189 , have been in a loss position for less than 12 months and four of the securities we hold, with a fair value of $ 390 , have been in a loss position for greater than 12 months . We do not believe these securities are impaired primarily because they have not been in a loss position for an extended period of time, the financial conditions of the issuers of these securities remain strong with solid fundamentals, or we intend to hold these securities until recovery, and other factors that support our conclusion that the loss is temporary. During the six months ended June 30, 2017 and 2016 , we received gross proceeds of $ 12,791 and $ 8,685 , respectively, in connection with the sales of available for sale securities and recorded gross realized gains totaling $ 452 and $ 375 , respectively, and gross realized losses totaling $ 171 and $ 140 , respectively. We record gains and losses on the sales of our available for sale securities using the specific identification method. (3) The investment strategy of this fund is to invest principally in fixed income securities issued by non-U.S. issuers. The fund invests in such securities or investment vehicles as it considers appropriate to achieve the fund’s investment objective, which is to provide an above average rate of total return while attempting to limit investment risk by investing in a diversified portfolio of U.S. dollar investment grade fixed income securities. There are no unfunded commitments and the investment can be redeemed weekly. (4) The investment strategy of this fund is to invest principally in fixed income securities.
