Steps 7 and 8: Settling in and readjusting

Step 7: Give it some time

Sharing a home is an adjustment for everyone. It's hard enough to live with a relative, let alone a perfect stranger. Check in regularly over the first month or two, but don't take older adults' complaints about minor transgressions too seriously. A little friction is normal.
Suggest that everyone sit down together after the first week or two to talk about how it's going and iron out any miscommunications. Encourage them to be flexible about the renter's ways but also open to talking about problems.

Step 8: Be prepared to readjust

If they start complaining a lot, look at their contract and make sure all the points in the agreement are being kept. If their need for help has increased since the lease was signed, talk to the renter about the possibility of reducing his rent and increasing his responsibilities. If he's not willing, you may need to hire some additional help or see whether he's willing to tear up the lease and let you find a new housemate.

If those solutions don't work, it may be time to consider another living arrangement, such as assisted living.
