There is one for sale that the current owners, who are not having much luck selling, list in the details of the home that it is, 'Slightly Haunted.' See it in the video below.

Would you buy a home that includes that info?  They claim to have caught quite a bit of attention from ghost hunters and thrill seekers, but no serious offers.  This home is in Pennsylvania. At least they are being honest in disclosing the information.  Scooby doo needs to be invited to this open house.
