Is the home in a high-risk zone?
High-risk zones are the ones whose letter starts with A or V on the FEMA flood map. The zone belongs to the exact spot, so look up the home you are buying, not just the town.

So will the lender make you buy a policy? Here is the rule.
Will my lender require flood insurance?
Yes, if the home sits in a high-risk zone and the loan comes from a federally regulated lender or is backed by the federal government. The policy has to stay in place for the life of the loan. Your lender can ask for more coverage than the legal floor.
See the lender rule and how much coverage it takes.
What should I ask the seller?
Ask the seller three things before you sign. First, the flood disclosure that Florida law makes them give you. Second, any old elevation certificate, which can save you a new survey. Third, whether their NFIP policy can pass to you in writing at closing.
See the three questions and why each one matters. Read how taking over the seller's policy works.
Will the 30-day wait delay my closing?
Not if you set it up right. NFIP flood policies have a 30-day waiting period, but if you buy the policy as part of getting, refinancing, increasing, extending or renewing a loan on the home, coverage can start at closing with no wait, as long as the application and payment are in by closing. Ask in writing for the policy to start at closing.
Read how the loan exception works.
What will it cost?
Same flood zone, very different prices. Two homes on one street can pay very different amounts because of how high the first floor sits, the coverage chosen, the deductible and past claims at the address. Most of those reasons come with something a buyer can check or change.

Has this neighborhood flooded before?
FEMA keeps flood claims private by address, so no public list shows one home's claims. The flood report for an address shows the county's flood claims record and the questions to ask the seller about the home itself. Each county page also walks through the storms that brought the most claims there.
Get the flood report for the address. Or read your county's storm record:
- Collier County storms
- Hillsborough County storms
- Lee County storms
- Miami-Dade County storms
- Pinellas County storms
- Sarasota County storms
What happens if I skip it?
If the home is in a high-risk zone and has no flood policy, the lender must tell you to buy one. If you do not, the lender must buy a policy for you and bill you for it. You do not get to shop that policy, so buying your own first keeps the choice with you.

Questions Florida homebuyers ask about flood zones
Do I need flood insurance to buy a house in a flood zone?
If the home is in a high-risk zone (any zone starting with A or V) and your loan comes from a federally regulated lender or is backed by the federal government, yes. The policy has to last for the life of the loan.
Will flood insurance hold up my closing?
It should not. Buy the NFIP policy as part of the loan, ask in writing for coverage to start at closing, and get the application and payment in by closing. Then there is no 30-day wait.
Does the flood zone set my price?
No. The zone sets whether your lender requires a policy. The price depends on things like how high the home sits, the coverage, the deductible and past claims. Same flood zone, very different prices.
