A homeless group home for men bought a house next door to me several years ago. We were a little worried when this happened, but they have turned out to be very good neighbors - quiet, keep the lawn mowed, no police presence, or anything. As these folks replaced a bunch of real low-lifes, they have been a very pleasant surprise. The cops would visit the previous bunch on almost a weekly basis - and this occasionally included swat teams with flash-bangs, full military gear, etc. Provided lots of excitement, but got old rather quickly.
So we are very happy with the new neighbors.
