The NFIP 30-day wait and the loan exception

Will the 30-day wait delay your closing?

NFIP flood policies have a 30-day waiting period. The big exception: 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. If a new flood map just put your home in a high-risk zone, you can buy within 13 months of the map date and wait only one day. A lender asking for flood coverage partway through an existing loan does not skip the wait. Private flood policies set their own waiting periods, often shorter.

The loan exception has two parts. Ask in writing for coverage to start at closing. Then get the application and the full payment in at or before closing. Miss either one and the 30-day clock applies.

So what if the policy is not part of a loan? Here is when the clock starts.

When does the 30-day clock start?

Without an exception, a new NFIP policy starts at 12:01 a.m. on the 30th calendar day after the application date and the payment. Coverage you add partway through a policy waits the same 30 days.

Paying the agent is not the same as paying the NFIP. The clock counts from your application date only if one of these is true:

• the NFIP or the insurance company gets the application and the full payment within 10 calendar days of the application date, or
• the application and payment were sent by certified mail within 4 calendar days of the application date.

If neither is true, the clock starts the day they get it. On a tight closing, ask your agent how the payment is being sent and when it will arrive.

And what about a new flood map? Read the one-day rule.

Did a new flood map just put your home in a high-risk zone?

Then the wait can be one day, not 30. The rule covers a building that a new or revised FEMA flood map just placed in a high-risk zone (any zone starting with A or V). Buy within 13 months of the date the new map took effect in your community. Coverage starts at 12:01 a.m. the day after the application and payment.

After 13 months, the one-day rule is gone and the normal 30-day wait applies. For example, Broward's July 31, 2024 maps are past that 13-month window.

Not sure what zone you are in? Check my address and see the FEMA zone for that exact spot.

So does a lender's letter count? Not on its own.

Does a lender's letter in the middle of your loan skip the wait?

No. If your lender asks for flood coverage partway through a loan you already have, and the loan is not being made, increased, extended or renewed, there is no exception. The 30-day wait applies.

The one case that changes this is the map rule above. If the lender's letter came because a new flood map put your home in a high-risk zone, and you buy within 13 months of the map date, the wait is one day.

If you do not buy in time, the lender can buy a policy for you and bill you for it. You don't get to pick that policy. Read what force-placed insurance means.

Buying a home that already has a flood policy? Ask about this.

Buying a Florida home? Ask about the seller's flood policy

This is a tip, not an exception to the wait. A seller's NFIP policy can be assigned to the buyer in writing when the title transfers. Ask whether the seller's flood policy can be assigned to you at closing.

Assignment does not work for a policy that covers only contents, or for a building under construction.

Ask the seller for their old elevation certificate too. It can save you a new survey. Since October 1, 2024, Florida sellers must also give the buyer a flood disclosure at or before signing the sales contract.

Is a private policy faster? Here is what to know.

Do private flood policies have a waiting period?

Private flood policies set their own waiting periods, often shorter. Ask for the start date in writing before you count on it.

Some private flood insurers stop selling new policies when a storm is close. Each company sets its own rule, so don't wait for the forecast. Buying an NFIP policy when a storm is near won't help with that storm either. Hurricane season runs from June 1 to November 30.

A federally regulated lender must accept a private policy that meets the federal definition. See what that takes.

Questions Florida buyers ask about the flood insurance wait

Is there a waiting period for flood insurance?

30 days for a standard NFIP purchase. No wait when the policy is bought as part of getting, refinancing, increasing, extending or renewing a loan on the home. One day when a new flood map just placed the home in a high-risk zone (within 13 months of the map date).

Will the 30-day wait delay my home closing?

Not if you 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 coverage can start at closing with no wait.

My lender wants flood insurance on a loan I already have. Is there a wait?

Yes, 30 days. A lender asking for coverage partway through an existing loan is not an exception. The wait is one day only if a new flood map put the home in a high-risk zone and you buy within 13 months of the map date.

When does the 30 days start counting?

From the application date, if the NFIP or the insurance company gets the application and full payment within 10 calendar days, or it was sent by certified mail within 4 calendar days. Otherwise it counts from the day they get it. Paying the agent is not paying the NFIP.

Can I take over the seller's flood policy?

Often, yes. An NFIP policy can be assigned to the buyer in writing when the title transfers. It does not work for a contents-only policy or a building under construction. Ask the seller and your agent before closing.
