Afraid the house you want to purchase might be haunted? If that property is in the UK, the Ghostfinder Paranormal Society will check it out to make certain that no paranormal entities are around and will certify it ghost-free.
The service is only available until October 31st, and House Network, which has apparently contracted with the Ghostfinder Paranormal Society, says it isn't responsible for the results of the GPS's investigation if the Society actually finds a ghost on the property. Such an investigation can cost between 100 and 500 pounds. More here.
It's not clear to me, however, what happens if the purchaser, having bought the house believing it to be ghost-free, then finds that the property isn't free of a ghostly tenant. How does she 1) rid herself of the occupant 2) prove to the GPS that the tenant is there and 3)collect on any warranty that might have been issued?
