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)

I don't see why not, its not like the murderer can come back. Maybe I'd get a big area rug if there are any stains. If yall live in an older house or an apartment there's a good chance someone has already died in it.
