People over whom you have social interaction- neighbors, work peers and so forth- are on better behavior than arbitrary strangers.

This isn't a solid rule by any means, but I think most people with experience in retail know what I'm talking about... if someone thinks they're never going to see you again, they will behave very differently, and never for the better. There is a HUGE difference between your peers, neighbors, and "fellow humans".

OTOH, Airbnb and VRBO make pretty compelling arguments the other direction; I suspect this is at least partly due to security deposits and the reputation systems where owners can leave feedback about renters.
