Before ratification of a contract for sale or lease of a residential property built before 1978, what must a seller or landlord do?

The correct response highlights the importance of lead-based paint disclosure as mandated by federal law for properties built prior to 1978. Since lead-based paint can pose serious health risks, particularly to young children and pregnant women, the law requires sellers and landlords to inform potential buyers or tenants about known lead-based paint hazards.

Before any contract for the sale or lease of such a property is ratified, the seller or landlord must provide all relevant information regarding lead-based paint, including any known hazards and reports related to lead paint conditions in the property. This requirement is aimed at ensuring that individuals are aware of any potential risks associated with lead and can take appropriate measures to protect themselves and their families.

The other options, such as providing a warranty, offering a discount, or renaming the property for marketing purposes, do not address the legal requirements surrounding the health and safety issues related to lead-based paint. Therefore, they do not fulfill the obligations imposed by the law regarding properties built before 1978.
