It will work until his health gives out, at which point he will have a lot more money left that he would have if he had chosen "senior care" to start with.
What is not to like about that?
If he’s in good health now, why even go there? Unless his house taxes and insurance are eating him alive, or rental on an apartment.
My first husband’s health is badly deteriorating, refuses to sell his home (nice home, paid for, taxes about $400 a month, but in a democrat town whose crime rate has jumped from very low to dangerously high in the last 20 years). He wants to keep the house in case any of our kids needs a place to stay. (They don’t. Except for one, they all have their own homes). Right now, Medicare is paying for most of his hospital and short nursing home stays, but he’s not safe living alone, and our unmarried son is staying with him. The kids are trying to get him to sell it, and move to assisted living, but realistically, even with a government pension and savings, he knows that would soon take all his money, and he’d like to leave the kids something. Kind of a no win situation, depending on how long he lives.
