I've heard about this same thing too, Nakis. I even came across a classified ad once for a Victorian house that came "complete with ghost"! For some it would probably be a selling point. When my parents sold their old home, some of the locals who came by to look were very curious about the rumors of it being haunted. I've got to admit, unless it was really bad, I would probably keep my mouth shut and take my chances. I would not be sure if it was actually the house that was haunted, or if it was some of my belongings, etc... Some have experienced hauntings in a house when later owners have reported nothing unusual. Wasn't there a well-publicized case in England a few years back in which a couple got out of the contract on this?
