Senior Housing Properties Trust (SHPT) offers those in their golden years a place to rest their weary heads. The real estate investment trust (REIT) owns some 300 health care-related properties in more than 30 states and Washington, DC. Its portfolio includes senior apartments, independent and assisted living facilities, nursing homes, medical office buildings, biotechnology laboratories, rehabilitation hospitals, and gymnasiums. Tenants, such as Sunrise Senior Living and Brookdale Senior Living, sign triple-net leases, which require them not only to pay rent, but to also pay operating expenses, remove hazardous waste, and carry insurance on their properties.
