随便搜了一下, agent 不一定有责任告知。 如果你的州agent有责任告知而没有, 请投诉或起诉。 如果没有责任, 有理由说人家 “坏得冒油” 吗?
Your Real Estate Agent’s Role in Flood Disclosure
Real estate agents might tell you about a property’s flood history when you first buy it, but they’re not always required to. That’s because flood disclosure laws are different in every state. The amount of information a prospective buyer receives about a property’s flood risk can vary widely, and the same is true for other environmental risks like wildfires. Only about half the states require that information about flood risk be disclosed to homebuyers at all, and just two Western states require disclosure of wildfire risk.
