Would you rent or buy the home of your dreams if a brutal murder had taken place there? What if you got to live there rent-free? Would you think twice if neighbors warned you that it was haunted?
Hard to say, personally.
I suppose none of us know what went on in our homes before we bought them - Ignorance is bliss.
I find it weird when I remember, however, that my neighbour was murdered. They were out for a walk, locally at the time, so it din't happen next door. Sadness is all around us.
