If 'creepy' is high on your list of new house requirements, you need to book a viewing for the Amityville Horror house in Long Island, New York.
Back in 1974, Ronald DeFeo Jr shot dead six members of his family in the house. Just a month later,George and Kathleen Lutz, along with their children, replaced them as residents. As the tale goes, they faced a supernatural onslaught, everything from sinister images to slime from the walls and a plague of insects, not to mention being awoken at 3:15am nightly (the time of the killings), with Mr Lutz also claiming to have seen his wife levitate and his daughter seeing a demonlike creature. They fled after less than a month and the rest, as they say, is history.
