Found out a month after buying our new house the reason we never saw our neighbors. They were in the midst of a divorce, but still living in the house, with the wife's boyfriend. So visits were a bit awkward. Fortunately that was right after the housing crash, so they were only stuck in the house for 2 years.
A lovely young couple bought the place and spent a year renovating it to live in with their kid...then divorced 6 months later. I don't think couples should live in that house any more, there's too much bad juju stored up in the walls.
That sounds a lot like a lot crimes.
