I can't speak for condos, but for a single-family home not in a flood zone, 100 yards from the beach, and about 35 feet higher than beach level, it costs $348 a year for the maximum coverage allowed through NFIP ($250,000 building/$100,000 contents). Just got the statement yesterday. We purchased flood insurance after hearing about Katrina victims who were not reimbursed by their insurance companies because they were told that their homes were damaged by a flood, not a hurricane.
