Would you ever buy a house if you could get a really good deal on it, and it was right next to a lovely park and a trail, but a murder-suicide happened in it? (And it was cleaned and repaired)
Yes, if I didn't know any details about what specifically happened or where in the house it happened. I think I would just put it out of my mind and never think about so it wouldn't ever bother me. If I knew too much I could see it coming to mind more easily and potentially being an issue for me.
