It's the risk you take running an ABnB or renting your home out. When things go well you get a house paid for by someone else and life is great! You get a squatter and you lose a lot or just a little. Roll the dice. It's on you.

AbnB's and short term hotel like rentals subject neighbors to risks that $$ making landlords could care less about. I don't feel sorry for home owners rolling the dice and being raked over the coals by squatters. Live and learn - the theives do.
