Years ago, caveat emptor was the rule in real estate transactions. A home buyer's own inspection was considered reliable in determining if the house was structurally sound and habitable. Today, the situation is different. Potentially troublesome conditions in a house are easily concealed, and inspection by the buyer may not reveal latent defects. For this reason, the doctrine of implied warranty has replaced caveat emptor in many jurisdictions.
