Awareness of the danger of the presence of lead in homes is always increasing. Americans are increasingly health conscious and lead is a serious health issue for both children and adults.
Given the choice most people are going to choose to buy a home which is lead-free. So it’s just common sense a property containing lead will be less desirable than one which is lead-free or lead-safe.
One can only guess when mortgage companies will begin to require lead-safe certification.
There are well over a thousand current lawsuits involving residential lead content currently so it’s highly likely insurance companies will ultimately figure lead paint risks as they pertain to insurance rates or even as criteria to deny coverage for homes without lead-safe certification.
