To add to what others have said re: AirBNB, there have also been at least a few cases where renters refuse to leave the property and turn a mid-term rental into a sort of "squatting" situation, creating tremendous legal hassle for the owner. (Though I'm not aware of any cases where the squatter has actually managed to wrest ownership from the actual owner!)

Though not related to Airbnb, in Sweden there was a guy who couldn’t use his own apartment for one or two years since it was occupied by fraudsters. What a hellish situation that must be.
