If there are multiple offers on the property, however, and seller disclosures are against local custom, you might not want to take this approach. If you find yourself in a situation where you feel uncomfortable asking the sellers to itemize property defects, wait to raise the issue until you have a ratified contract. You could require that the sellers provide you with list of known defects as a condition of removing your inspection contingency. Buyers should have all their questions about a property answered before closing, not after. Complete disclosure before closing tends to minimize after closing litigation.
Full disclosure protects everyone involved.
