How Long Do NFIP Policies Last?
NFIP flood policies run for one year and must be renewed annually to keep coverage in force.

A Separate Policy
NFIP is the National Flood Insurance Program, a federal flood policy that runs alongside your homeowners policy, not inside it. Your lender may require both if the house sits in a flood zone. Check the lender's conditions for which ones are mandatory.
Renewal Isn't Automatic
An NFIP policy doesn't renew itself. You or your agent has to submit payment before the term ends. There's usually a grace period, but letting it lapse means no flood coverage until a new policy takes effect, which can take days to kick in.
The 30-Day Wait
A new NFIP policy typically takes 30 days to take effect, unless it's tied to a mortgage closing, which can waive that wait. If your closing date is close, ask your agent whether your purchase qualifies for immediate coverage.
Proof For Your Lender
Your lender wants proof the flood policy is active, usually a declarations page or binder showing the one-year term and the coverage amount. That dwelling coverage figure should match what the lender requires, often tied to your loan amount or rebuild cost.
The homeowners policy covering the house itself is a separate purchase from the NFIP flood policy, and its price and terms vary by insurer even when the coverage looks the same on paper. With a closing date set and a lender waiting on proof of coverage, comparing homeowners quotes now means one less number to chase down later, and a better shot at a rate that fits the budget.
What Happens When The Policy Is Up For Renewal
As the one-year term gets close to ending, you'll get a renewal notice from the NFIP, usually sent out 45 to 60 days ahead of the expiration date. It shows the new premium, which can be higher than last year's. FEMA adjusts flood insurance rates based on risk assessments that get updated periodically, so don't assume the number stays flat year to year.
Paying it isn't optional if you want to keep the coverage active, and more to the point, if your lender requires it. Most lenders that require flood insurance also require it to stay in force for the life of the loan, not just at closing. If the policy lapses and your lender finds out, which they will since they track this, they can buy a much more expensive policy on your behalf and bill you for it. This is called force-placed insurance and it's worth avoiding.
Many homeowners set up escrow for flood insurance the same way they do for homeowners insurance and property taxes. The lender collects a portion of the annual premium with each mortgage payment and pays the flood policy directly when it's due. If your loan has escrow, check whether flood insurance is included in it or whether you're expected to pay the premium yourself when the renewal notice arrives. Missing that distinction is one of the more common ways a policy lapses by accident rather than by choice.
If the flood zone designation for the property changes before a renewal, through FEMA remapping or a community's updated flood data, the premium can shift more than the usual year-to-year adjustment. Zone changes get reflected on the next renewal notice, not applied retroactively, so a property that was mapped into a lower-risk zone partway through the year won't see savings until the following term. Your agent can tell you whether a remap affects your property specifically.
What Happens When It's Time To Sell Or Refinance
An NFIP policy stays with the property's flood history, not just the current owner, and that matters more than most buyers expect. When a house sells, the policy itself doesn't automatically transfer, but FEMA does allow an NFIP policy to be assigned to the new owner at closing in many cases, which can preserve the pricing instead of starting over at the current year's rates. Ask the seller's agent whether the existing policy is assignable before assuming a fresh one is the only option.
Refinancing works differently. The loan itself is new, so the lender reviewing it will check flood zone status and coverage requirements again, even if nothing about the house or the flood map has changed since the last mortgage. If the property is still in a mandatory flood zone, the new lender will want proof of an active NFIP policy before closing on the refinance, the same way the original lender did. The one-year term doesn't reset just because the loan changed hands, so if the policy has eight months left, it keeps running on that schedule.
Selling a house with an older NFIP policy can be a selling point worth mentioning to a buyer, particularly if the property was mapped into a flood zone years ago and the policy has built up a pricing history that's more favorable than what a brand-new policy would cost today. That's not guaranteed and depends on how FEMA's rating has shifted for the area, but it's worth raising with the agent handling the sale rather than assuming the policy has no value beyond the current term.
None of this changes the answer to the original question. The policy still runs one year at a time no matter who owns the house or whether a loan is being refinanced underneath it. What changes is who's responsible for keeping it renewed and in force, and that responsibility moves at closing, not before. Anyone buying a house with an assigned or transferring NFIP policy should confirm the exact handoff date with the agent so there's no gap between when the seller's coverage ends and the buyer's begins.
Before Closing
Check your declarations page or binder for the one-year term dates and dwelling coverage amount. Confirm they match what your lender asked for, and ask your agent whether your closing date waives the 30-day wait.
