In the hills of Knott County, Kentucky sits an old abandoned nightclub. But at one time, it was the home of cult leader Charles Manson. You can read about it here:

Most people do not know this; but Manson's Kentucky roots run deep. But anyway, this building is now for sale. And I am not saying that it IS haunted; but I've read posts online that state that it is. But even if it is haunted, I highly doubt that it's haunted by Charles Manson considering he was just a small child when he lived there for a short time.
But for $20,000.00 someone could own a remarkable piece of history. And I think if someone would convert it into a Bed & Breafast / Museum type of venue, that they could make some money. Paranormal teams would flock to it to investigate. Historians would come just for the historical aspects of the place, and Manson enthusiasts would visit it as well.
