Carey (NYSE: WPC). Sabra has 416 properties in its portfolio, with 279 skilled nursing centers and the rest scattered among senior housing communities and behavioral health and specialty hospitals. That diversity, along with rent flow that is 60% from leases tied to the consumer price index, has helped this REIT post market-crushing performance, nearly quadrupling the S&P 500 in total return since it went public in 1998.
