Some single seniors are turning to roommates and other alternative living situations. One 64-year-old senior in Chicago, Bonnie Jackson, contacted a local center of National Shared Housing Resources to help her fill the two unused bedrooms in her home, and receives $500 a month for each room, giving discounts to tenants who help her run errands or change light bulbs. Another woman in her late 50s formed her own community in Silicon Valley by buying two homes in a three-house enclave and renting her second property to two other single women.
