I see no reason why the house cannot be bought and resell.... Depending on how e owner was murdered... If it was spiritual attack i think its best to leave the house...When it comes to selling a house, do you have worse luck if you're trying to sell a house where a person died? Maybe it was murder. And speaking of which, would you even buy a house where someone died, either by natural causes or murder?
I honestly don't know. I can't imagine that you are even required to tell people if someone died there. I imagine with murder it's different. If you sell a house, are you obligated to give the houses history to people?
