Flooding Due Diligence

Hello MHU Community,

I have a question regarding flooding risk I’m hoping the forum can help with. When performing your initial due diligence (prior to hiring professionals) how do you:

-Go about determining a property’s flood risk and flood history?
-Get comfortable with the risk? Is there a common go / no-go rule of thumb?
-Any other helpful tips or info?

Thank you,
Brendan
