I have to wonder...
I really wonder WHY any homeowner would want to go on this, or any other show, to proclaim that the house they own is haunted? If they ever go to sell, their property value will go down significantly if it becomes stigmatized as "The Scary Haunted House". If you truly believed you were being haunted, wouldn't it be better to handle it quietly and not so publicly?
I know that disclosure laws for Real Estate vary State to State, but it is my understanding that in many cases if a property becomes notoriously and publically known for something that could negatively impact the privacy and/or quality of life for the new owners that they may have to disclose that. Plus the show is a sort of public record that you, as the homeowner, believe the home to be haunted and a quick google search would bring that up.
I really do not see any benefit to the homeowners to want to go on this show. Do you?
