ALEXANDRIA, Va. -- Those who purchase homes and later find they might have "unwanted guests" may not get much help from the law. But there are other ways to cleanse the property.
Most states do not have real estate laws that require the seller to admit suspicion of the paranormal sort.
According to Realtor.com, 38 percent of buyers would change their minds on a house if they believed it could be haunted.
That is where people like father-daughter team Mike Robishaw and Sara Christopher of Alexandria Paranormal Investigations come in.
"If you love this house, don't let something like [a haunting] turn you away from your dream home," Christopher said.
Robishaw said he has empowered hundreds of people to feel comfortable in a home they believed could be haunted.
"You can negotiate with [ghosts] enough until they will just move on," he said.
To check to see if a house might have some psychological stigmas prior to purchasing, sites like DiedInHouse.com have been created, where -- for a price -- buyers can see if a murder, suicide or death happened in a home.
