Ok, so my FIL is 83 and we are all moving in together because he's no longer able to live on his own. He will have a full apartment of his own and we all know he won't last forever. Once he's gone, our thought was to rent it out because it's going to be a full apartment that's just sitting there doing nothing otherwise. Obviously, I don't want to take advantage of someone else but housing in my town has gotten crazy scarce so NOT renting it seems like a bigger hit on someone than renting. The money we get will of course go to the mortgage. Is there a way to do this without immediately being labeled as an exploiter? I'm not looking to get rich, but there's no reason to just leave a perfectly nice apartment empty.
