Agreed that we all put our rental houses at risk, just about every time we blindly book.
It is spring break, being such, I have blatantly asked people if their intent was to throw a party. I have also tactfully explained that my house is nice. I remodeled the entire place myself, I clean it and manage it myself and I am a little overprotective, maybe.
I’ve found that if the stay is legit; holiday, business, etc. people usually have no problem describing themselves and their situation. A couple of times people have not responded to this type of inquiry. I have to assume, that they’re intent was not in my houses best interest.
I would rather take the chance of offending a potential guest, than having someone trash one of my places.
Again if the questioning is done in a truthful and tactful manner, there is no real reason for a guest to be offended.
Just my 2 cents.
