When a real estate agent works with a prospective homebuyer, they're required to point out physical or material defects in the property.

A death on the property? It depends on the state where the house is located. In most states, death doesn't count as a material defect requiring disclosure.

Some homes are considered "stigmatized properties," or dwellings that have been "psychologically impacted by a past or suspected event on the property, but has no physical impact of any kind," according to the National Association of Realtors. 

Stigmatizing events include murder, suicide, alleged hauntings or a notorious previous owner, NAR noted.
