I had an experience of offering a house for sale where somebody died. Initially, I didn't know that the house has a "history" and I wasn't informed by the owner about it. I eventually learned about its history from the neighbors and verified what I learned with the owner. The owner admitted that indeed somebody died in the house. From then on, I tried to offer the house with a "briefing on its history" to the potential buyer. So far, no takers. To these day, the house is still unsold and unoccupied.
True or not, I guess a lot of people still consider properties tagged as "haunted" as macabre reminders of the past.
