My best advice after our family going through the same thing (my father and his 2 sisters). They all 3 sat down and had a meeting. It was agreed that sister 1 could live in the house and pay fair market rent, slightly lower due to income. HOWEVER, that paid rent went into a trust account. This account was then divided amongst all three parties when the home was sold, PROVIDED that sister 1 left the house in as good a condition when moved into. If not, the money in escrow went towards repairs. It worked out awesome. This way nobody was mooching off anyone, and in the end sister 1 got a little of her rent money back. GET A LAWYER TO SIGN ALL AGREEMENTS AND PAPERS so someone can’t change their mind suddenly.
