Some great points, @bitcoin_citizen -- each state is very different (in mine, lawyers are required for closing even if you have an agent, and you have to hire one separately). Our buying agent definitely got us through some of the legal and bureaucratic paths we had to navigate (as well as giving us good advice and advocating for us in general).

I have a friend in a similar accidental landlord situation, and don't envy either of you (especially since landlord/tenant law is its own thing, and also varies a ton between states). Good on you for stepping in to make sure your mom's set.
