Some state have the legal requirement that if the place was the location of a violent crime that has to be disclosed to the prospective buyer. If it is an issue to the buyer I think they should do their homework and google it or make it part of the title search.
When we sold Janet’s Father’s home after he passed away in 2001 (heart failure death at home), the realtor told us that we would have to disclose the death to the buyer before the closing. She did that and apparently it didn’t affect the sale. I am not sure if it was a legal requirement (California) or the realtor’s way of controlling the deal.
