Depends on if the house is worth it. If it's run down, needs work, in a bad neighborhood then definitely not.
Could I, yes.
Would I? Not if I knew about it before buying the house!
Depends on what has been done to it since the crime was committed.
My ex boyfriends dad lives in a house where 3 people were murdered it creeped me out going there but it doesnt bother them at all i couldnt do it but hey they got a great price on the house
