Your haunted house is the prefect place for a Halloween party.  Other parties have to spend lots of money creating the illusions of ghosts and ghouls.  It takes lots of wires, motors, and smoke machines.  You, however, were lucky enough to end up with a truly haunted house.  Sure the spirits keep you up at night, but all your friends say you have the best Halloween parties.  I mean, no one is willing to spend Christmas at your place.  But once a year, October 31st, it's all worth it.

But now, you decided to take a job in Salem and you have to sell your home.  Do you advertise that it's haunted?  Perhaps people will pay a premium for poltergeist.  Or do you paint over the bleeding wall and keep it all a secret? 

I'm not going to tell you what to do, but you should familiarize yourself with the law.  The state of Minnesota requires a nine page disclosure.  In which, it is necessary to disclose any material facts that would affect the normal use and enjoyment of the home by any future buyer.  But you are in luck.  There are a few exceptions to this rule.  And one of them is haunted houses.

Page 9, lines 39-42:  There is no duty to disclose the fact that the property…was the site of a suicide, accidental death, natural death, or perceived paranormal activity.

But I assure you, after the new owners move in and meet the neighbors, they'll learn all about your paranormal parties.  And expect their lawyer to come knocking, regardless of duty to disclose.
