He's probably safer there than out on the street or living in a car somewhere.

Sadly I think there's going to be a lot more of this in the coming years (more older folks retired either voluntarily or not who haven't saved enough to retire with a normal standard of living). Sad, but if he's not hurting anyone or bothering anyone I'd leave it alone - maybe leave some groceries and stuff where they'll be found to help him out.
