When does a new NFIP flood insurance policy usually take effect?

30 days after you buy it, with a few exceptions.

  1. Immediately at purchase
  2. 30 days after purchase ✔
  3. The next time it rains

Why: The standard wait is 30 days, so buy before a storm threatens. There is no wait if you buy while making, increasing, extending or renewing a mortgage.

Huh, didn't know that: A one-day wait applies if you buy within 12 months of your property being newly mapped into a high-risk zone.
