Your post makes it seem like you have an emotional/sentimental attachment to the home.

We need to to warn our guests about these things and *hope* they heed the warning and protect their loved ones.By the way, (although a different pet topic) speaking of pets:To everyone reading that owns or is considering owning a STR that either does not allow pets, or charges for pets, make sure you research (Not ask for free advice) or consult with an attorney about "pets" VS "ESA"'s (emotional support animals) VS "SA"'s (service animals).

Your contract will dictate how you can get out of it, but really need to remove emotions before jumping to solutions you might regret.

Assuming it is in livable condition and not in need of a full gut remodel or full of mold/fire damaged, etc, an owner-occupant will pay your more than any investor will, since you are selling to someone's emotions versus a profit motive.

I'm just saying this so that you don't make an emotional decision based on some temporary expenses.Whether you sell or rent should depend on your longer term goals and what you can get for selling vs renting it.

I realize it is difficult to get started if you have never done this before .. and I applaud you on geting resourceful but .. this deal can go bad in so many ways .. divorce lawyers .. bank repossession.. and just desperate people involved.. somebody might be the nicest person in the world but put them through a divorce or a stressful situation that involves a highly emotional state of mind .. and , you can almost see them change in front of your eyes ...
