Haunted houses have been scaring us since Edgar Allen Poe wrote “The Fall of the House of Usher” in 1839. Almost every city has a big old house that children — and some grownups — think is haunted. Many kids earned their first badge of courage by sneaking a peek into the window of a house where someone once went in and was never seen again or where a neighborhood teenager claimed to have seen a ghost. Some of these homes, currently for sale and showcased at TopTenRealEstateDeals.com, are fascinating but nevertheless creepy. Maybe that’s why they’re on the market.
