Here’s a clause from the sales agreement that I signed when purchasing my house:
“The Seller warrants that, to the best of their knowledge,
belief and understanding that this property has not been stigmatized
by any act or occurrence which would be considered
traumatic or horrific to the buyer.”
While not required by local law, I was told that this is common language in sales agreements. When I asked what was meant by “traumatic or horrific”, I was told it was meant to cover both murder and haunting! Oooo-kay.
That being said, I would draw the line at living in, say, John Wayne Gacy’s house. Not because the idea of a murder having occurred there bothers me, but the fame of the location would draw unwanted visitors.
