@Mike1034, I don't get it. It's the host's property; not the guest's. It's the host's responsibility to have the place in order and taken care of; not the guest's. The host is the one being paid.
@Emma681wasn't specific to how much water was running... and I'm just assuming that this is not a home-share property or this would have been noticed quickly. And even if, how long do you wait to check the place after a guest leaves? Whose responsibility is that? The host.
This really does not reek of "home abuse" by Emma's description.
The very best way to screen is in advance of renting. Have a couple/few conversations and get an idea of expectations. This isn't a guarantee, but it sure lessens your "risk" if the person becomes less of a "stranger" before they arrive. If you don't have some kind of communication /relationship and you don't really have much/any contact during their stay, then you are essentially a little hotel. And what do hotels do? They just suck it up.
Women have menstrual cycles. Embarrassing things can happen. Stuff can get tracked into the house. Sometimes the knob on the faucet isn't quite turned off... Whatever.
Really, if y'all are so concerned about little things like this, you will not be happy doing it.
Charge more, and get to know your guests.
Best,
Kim
