There is always someone somewhere that will buy a house even if it has a very bad history, If they cant sell it probably the asking price is too high, if they really cant move it, pull it down and plant trees on it to blend with the surrounding area.
Another house with a bad history from WW2 is in Poland, it was occupied by Amon Goeth the commandant of Plaszow Camp during WW2, (Shindlers List) It lay empty for many years until someone came along and purchased it, renovated it from top to bottom and now presumably lives in it despite its terrible previous occupant.
