Aqua Teen Hunger Force made a good point: if you're house is haunted, don't panic and stay, just sell it to a rock star. When their neighbour found out his house was haunted, he sold it to Danzig. "Do you think we can get the elven blood to run up the walls?" "I don't see why not."
Considering that Trent Reznor, then Marilyn Manson, bought a house where Manson family murders took place, this is probably not too far off.
