Not really. Maybe for a little while, but once we sell the house, he has to leave.
And the guy isn't all that "set"--he has some cognitive issues, no job skills, a part time minimum wage seasonal job, a very limited amount of money from the sale off the house, and virtually no Social Security credits at 55.
If I were him, I wouldn't feel "set" at all. Hopefully he can get some affordable housing somewhere, or if he were truly smart, he'd move to Florida and get a very inexpensive condo or mobile home (while he still has a few bucks left) near a golf course where he can continue to work in his field. But he's not truly smart.
