Subsequent Events [Abstract]
Subsequent Events	Subsequent EventsIn November 2022, we entered into definitive agreements to effectuate the transition of 147 skilled nursing facilities currently operated by ProMedica. As part of the agreement between Welltower and ProMedica, ProMedica will surrender its 15% interest in the skilled nursing facilities currently owned by the existing joint venture and provide significant working capital support for the new operators to ensure a smooth transition of patient care and operations. In exchange, we will release ProMedica from its skilled nursing lease obligation. The 58 private-pay assisted living and memory care assets in the ProMedica joint venture will continue to be operated by ProMedica under a lease backed by the existing guaranty. Concurrently, we entered into a definitive agreement to sell the 147 skilled nursing facilities to a newly formed joint venture owned 85% by Welltower and 15% by Integra Health (“Integra”). Welltower and Integra will enter into a master lease agreement for the portfolio with plans to bring in select regional operators across various states that will operate the facilities upon receiving regulatory approvals.
