And what happens when 6 months later that seller is at, say a family reunion and talking to wife's 2nd cousin Fred, the Real Estate Attorney from whatever towns away, and something get's mentioned of it and Fred get's all interested and tells em that's illegal and hes now implicated in a crime and holly-cow hes gotta report this to police NOW and geeks out on seller, so seller starts geeking out thinking "I'm too pretty for prison" and so on and so fourth....

Have you reported this theft to the police?

If there is a fire, heating issue, tenant argument, police issue, inspection, etc...
