There is no tidy rule for this one. The owner generally absorbs the value hit, and in the worst cases the only cure is demolishing and rebuilding. A property that becomes notorious can take a real, lasting hit to its value. In a smaller, tight-knit community it may be effectively unsellable in its existing form. Two things are worth knowing at a general level: - Disclosure duties vary by state. An owner may carry an ongoing obligation to disclose material history, so this is a question for a local real estate attorney rather than a rule of thumb. - Insurance will not make you whole. Standard homeowners policies cover physical perils. A drop in market value because buyers no longer want the address falls outside that coverage, so the owner eats the loss. If you are a landlord sizing up worst-case exposure, the honest picture is limited insurance protection, state-specific disclosure duties, and a value hit that may only be cured by rebuilding. Confirm the specifics with local counsel.
