This intergenerational matchup ends up being a positive for both parties in a variety of ways. The senior usually charges their tenant rent that is much less than the going market rate.
If you’re in the United States, a good place to start would be the National Shared Housing’s homesharing directory. You’ll find the names and contact information of agencies located throughout the U.S.
While homesharing agencies vary in their policies, their mission is to match the home provider with an appropriate home seeker so that both parties can mutually benefit.
As affordable housing becomes more difficult to find, I’m seeing more housing organizations and nonprofits adopting a homesharing model. There are now group shares for families with children.
