I saw this news article a few weeks ago. It looks like the house is up for sale again -
"The owners of The Amityville Horror house - an iconic piece of scary movie history - have put it back on the market with a dropped asking price of $955,000, insisting it is because they are getting divorced and not because it is haunted."
I think two families owned it since .I could be wrong ,but my uncle had a house on the water in Amityville,so he drove me by the house ,and I was barely 11 . So I've seen it up close .
Anyone who lived there after the family ,said nothing occurred ,at all .
