This is a composite, illustrative example, not a single named individual's account.
After her adult children moved across the country, one solo ager used a local home-sharing program to rent a room to a graduate student in exchange for reduced rent and light help with errands. The arrangement addressed both her finances and the daily companionship she'd been missing.
The lesson: home-sharing programs typically include a vetting process similar to a roommate service, worth researching before assuming it's too complicated to arrange.
