The days when a seller could say, "Here's the house, hope you like it," while failing to mention its hidden flaws, dangers, and weak spots, are pretty much over. Almost every U.S. state has passed laws mandating that sellers give buyers specific information about what structural and other features the house contains, and their condition. In some cases, the brokers must speak up about hidden conditions, too. Many states have created standard forms with which sellers are expected to record and pass this information to buyers.
