Final answer:
The requirement for a seller's agent to disclose a death from a heart attack in a home depends on state law, with some requiring disclosure under stigmatized property laws and others not considering it a material fact that must be disclosed.
Step-by-step explanation:
The necessity for a seller's agent to disclose that someone has died of a heart attack in a home to potential buyers varies depending on state laws and regulations concerning real estate disclosures. In some states, deaths in a home, particularly those from natural causes, do not constitute material facts that must be disclosed. However, in states with stigmatized property laws, there might be a requirement or an allowance for disclosure. The concept of a material fact in real estate is generally reserved for physical conditions affecting the value or desirability of the property. It is advisable to consult with a local real estate attorney to understand the specific disclosure requirements in a particular jurisdiction.
