Related Party Transactions [Abstract]
Business and Property Management Agreements with RMR	Business and Property Management Agreements with RMR We have no employees. The personnel and various services we require to operate our business are provided to us by RMR. We have two agreements with RMR to provide management services to us: (1) a business management agreement, which relates to our business generally; and (2) a property management agreement, which relates to the property level operations of many of our properties, including our medical office and life science properties, and major renovation or repositioning activities at our senior living communities that we may request RMR to manage from time to time. See Note 11 for further information regarding our relationship, agreements and transactions with RMR. We recognized net business management fees of $3,763 and $5,986 for the three months ended September 30, 2022 and 2021, respectively, and $13,082 and $17,627 for the nine months ended September 30, 2022 and 2021, respectively. Based on our common share total return, as defined in our business management agreement, as of each of September 30, 2022 and 2021, no estimated incentive fees are included in the net business management fees we recognized for the three or nine months ended September 30, 2022 or 2021. The actual amount of annual incentive fees for 2022, if any, will be based on our common share total return as defined in our business management agreement, for the three-year period ending December 31, 2022, and will be payable in January 2023. We did not incur any incentive fee payable for the year ended December 31, 2021. We recognize business management and incentive fees in general and administrative expenses in our condensed consolidated statements of comprehensive income (loss). RMR provides management services to our joint ventures. See Note 11 for further information regarding our joint ventures' management arrangements with RMR and the related impact on our management fees payable to RMR. We and RMR amended our business management agreement effective August 1, 2021 to provide that (i) for periods beginning on and after August 1, 2021, the MSCI U.S. REIT/Health Care REIT Index will be used to calculate benchmark returns per share for purposes of determining any incentive management fee payable by us to RMR, and (ii) for periods prior to August 1, 2021, the SNL U.S. REIT Healthcare Index will continue to be used. This change of index was due to S&P Global ceasing to publish the SNL U.S. REIT Healthcare Index. We recognized aggregate net property management and construction supervision fees of $2,658 and $2,931 for the three months ended September 30, 2022 and 2021, respectively, and $7,567 and $9,276 for the nine months ended September 30, 2022 and 2021, respectively. For the three months ended September 30, 2022 and 2021, $1,521 and $2,410, respectively, of the total property management fees were expensed to property operating expenses in our condensed consolidated statements of comprehensive income (loss) and $1,137 and $521, respectively, were capitalized as building improvements in our condensed consolidated balance sheets. For the nine months ended September 30, 2022 and 2021, $4,142 and $7,360, respectively, of the total property management fees were expensed to property operating expenses in our condensed consolidated statements of comprehensive income (loss) and $3,425 and $1,916, respectively, were capitalized as building improvements in our condensed consolidated balance sheets. The amounts capitalized are being depreciated over the estimated useful lives of the related capital assets. We are generally responsible for all our operating expenses, including certain expenses incurred or arranged by RMR on our behalf. We are generally not responsible for payment of RMR's employment, office or administrative expenses incurred to provide management services to us, except for the employment and related expenses of RMR's employees assigned to work exclusively or partly at our properties, our share of the wages, benefits and other related costs of RMR's centralized accounting personnel, our share of RMR's costs for providing our internal audit function, or as otherwise agreed. Our property level operating expenses are generally incorporated into the rents charged to our tenants, including certain payroll and related costs incurred by RMR. We reimbursed RMR $3,498 and $3,121 for these expenses and costs for the three months ended September 30, 2022 and 2021, respectively, and $9,573 and $9,620 for the nine months ended September 30, 2022 and 2021, respectively. These amounts are included in property operating expenses or general and administrative expenses, as applicable, in our condensed consolidated statements of comprehensive income (loss) for these periods. On June 9, 2021, we and RMR amended our property management agreement to, among other things, provide for RMR's oversight of any major capital projects and repositionings at our senior living communities, including our senior living communities which Five Star is continuing to manage, and that RMR receives the same fee previously paid to Five Star for such services, which is equal to 3% of the cost of any such major capital project or repositioning.
