While the brothel example might not be distinguishable from a couple on vacation having a party, except for the money-changing-hands angle.
Lets admit, its the moral angle at issue. The rest is after-the-fact arguments pasted on to make it seem like an objective thing.
As to wear and tear... it's a brothel... and not in a movie; you might be surprised at the turnover.
Edit: I realize that "have no patience for" sounds pretty snotty... I've been a little sleep deprived lately and it isn't bringing out the best in me, sorry.
Edit 2: I also realize that the issue of the brothel, totally aside from the homeowner's feelings, might represent a property value issue, in the same way as a previous murder. It doesn't have to sensible for it to hit him in the pocket; obviously sex work doesn't leave some kind of "spiritual residue" anymore than violent death, but people are often irrational.
