This ought to be on the disclosure forms you fill out when dealing with real estate: Is the property inhabited... by any ghosts or spirits? A restauranteur (a Chinese-American JW -- huh?) balks at moving into the building he leased because it's haunted. Is it his own fault for not getting a proper building inspection done?
In my small southern state, you have to disclose if a property is "stigmatized" -- that is, if you know that there was a murder, suicide or other death in teh house, or if the house has *a reputation* of being haunted. Such a disclosure rule would have helped this situation by not letting it happen in the first place.
