Do you need to mention if someone died in the house you're selling?

I think it needs to be brought up if it was a place where someone was murdered, or a serious crime. I think if someone dies due to natural causes, it does not have to be addressed, because lets face it, a lot of house sales would need to include every single death. Including ones from 100s of years ago? What if you purchase an old house that's hundreds of years old?

No, not unless it was tied to criminal activity. This is the same for a family who was cooking up drugs in the home. It has to be stated on public record that there was a criminal offense that occurred. Some areas may overlook this but I know where I live, this is a must. You are not legally bound to tell a potential buyer that someone died in the home however. If they died do to age, an accident, or illness, it doesn't need to be put on public record.

Some states will require it to be publicly documented so if the buyer asks, you are legally bound to tell them what happens and where the death took place. In my state, this is the case but very few people inquire about deaths so it is a non-issue.

Do you have to disclose a death in a house? Some buyers may prefer not to think about this unpleasant subject, but others may insist on finding out what major life—and end-of-life—events occurred inside a prospective home. In most cases, if someone has passed away peacefully in a house, there’s no legal obligation in most states requiring that [sellers] disclose it,

A peaceful death is another matter. Let’s not forget that a century or so ago, dying at home was the norm—few people went to hospitals. If every house where someone had died a natural death became stigmatized, there would be a lot fewer saleable houses in the United States. Sure, a few people might be sufficiently put off to look elsewhere, but plenty of buyers see the home for what it is—an empty structure, waiting for them to bring new energy into.
