This is one of a series of booklets prepared as a resource for the American Association of Retired Persons' (AARP) Consumer Housing Information Service for Seniors, a local AARP volunteer program that uses trained Housing Information Volunteers to provide impartial information to older people who have questions of concern about how to find safe, comfortable, affordable housing; how to cut household expenses or use their homes to earn extra income; home maintenance and home improvement; tenants' rights; and local housing subsidy or in-home assistance programs. This booklet provides an overview of homesharing, an arrangement by which two or more unrelated persons share a dwelling in which each retains a private space. It notes that a homesharing arrangement might involve a homeowner and a renter or persons renting a house or apartment together. The ability to tailor a homesharing arrangement to the needs and desires of the persons involved is shown in examples of homesharing with older peers and intergenerational homesharing involving a service exchange. Questions are provided which can help homeowners decide if homesharing is right for them. Considerations which are necessary to make homesharing work are discussed. Two self-questionnaires are included, one for those considering sharing their homes or apartments, and one for those interested in sharing someone else's home or apartment. Guidelines for a lease in a homesharing arrangement and a list of sources for additional information are appended. (NB)
