If Hollywood has taught us anything about house buying in creepy films you should check:

• The house was not built on ancient Indian burial ground
• No one died in the bath
• If its a mansion and its been sold at a fraction of its real value, its probably haunted
• The house was not built on the ground of an ancient orphanage. According to Hollywood bad things usually happen here and there will be ghosts
• The house was not built on the grounds of an old hospital, ghosts of dead patients.
• Find out if the previous occupants are still alive
• Find out if the previous occupants had a tendency to go crazy with chain saws
• Check the basement for a doomsday door or well with a crazy creature inside it.
• Check if anyone of the previous occupants were burnt alive for witchcraft. She/He will probably haunt you.
• If your dog, cat, mouse or what ever creature you have acts strange in the house or barks/squeaks at thin air don't buy it, its probably haunted.
• If your kids suddenly start having imaginary friends they never had before that ask them to climb on the roof of the house, its probably haunted.
• If your kid finds a strange scary looking doll at the new house and starts acting strange take it away leave it in the house and run. Its probably haunted.
