Beach houses in Quincy, MA: Flood / Hurricane Insurance Costs

[Kurt F.]

Greetings --
My sister lives on the east coast and is looking to buy her first home -- on the beach in Quincy, MA. I know nothing about property there, as I live in Iowa. She is looking in the 450,000 dollar range -- given that, can anyone give me a heads up on the insurance that will be required on the beach in that type of location? Standard homeowners, of course, but how about flood and hurricane coverage? Any input on the costs involved for flood hurricane insurance?
Thanks in advance.
