If you (or one of your children) can offer any kind of credible proof that the grand old house you just purchased for cheap is haunted, drop the caulk gun and get out. We've seen too many families attempt to stick a haunting out: The Amityville Horror, The Shining, Paranormal Activity. Your attempts to shun the dead will prove futile as evil spirits use you for a nice game of possess and kill. Just sell the house and take the loss, okay?
