Retirees purchasing waterfront homes may face years of 18% flood insurance increases

Private flood policies often provide broader protection because federal coverage has limits.

For retirees, the cost of flood insurance can become a lasting and unwanted part of owning a home near the water.

What to know

According to 24/7 Wall St., homes in Special Flood Hazard Areas that are financed with federally backed mortgages must carry separate flood insurance because the chance of flooding there is at least 1% a year. That policy is distinct from standard homeowners insurance, which does not include flood damage.

Flood risk calculations account for heavy rain and other kinds of flooding. Most policies are issued through the Federal Emergency Management Agency's National Flood Insurance Program.

Under the program's Risk Rating 2.0 system, pricing is based on home-specific factors such as how close the property is to water, the type of foundation, floor height, and estimated rebuilding costs.

Premiums for primary residences can rise by up to 18% a year, while second homes can increase by as much as 25% until they reach the full rate.

Those adjustments gradually move older discounted policies toward prices that reflect the home's full flood exposure.

More context

For retirees living on a fixed income, repeated increases can put pressure on a budget that was already tightly planned.

In 24/7 Wall St.'s example, a primary home with a $3,000 premium and annual increases of 18% would climb to about $4,930 after three increases and $6,860 after five.

That would leave homeowners paying roughly $3,860 more each year than expected. Based on the example's assumptions, covering that added annual cost through a 4% withdrawal from savings would require about $96,600 in additional retirement funds.

The federal program limits single-family home coverage to $250,000 for structural damage and $100,000 for belongings, even if a waterfront property would cost much more to rebuild.

Choosing flood insurance adds another factor as buyers balance premiums, property taxes, homeowners insurance, and the purchase price.

Private flood policies generally offer more coverage because federal protection may not be enough.

What can help?

FEMA provides premium discounts for elevating a home, moving equipment such as furnaces and water heaters above the lowest floor, and adding vents that allow floodwater to pass through lower walls.

Some property owners may also qualify for savings of 5% to 45% through FEMA's Community Rating System. An elevation certificate, which documents a surveyor's measurements of a home's height, can also help lower premiums.

Buyers can consider assuming the seller's policy to keep its claims history and annual increase cap, or request a quote from a private insurer. FEMA's FloodSmart website offers flood-zone and local claims information to guide those choices.

A cash purchase does not avoid the waiting period, while coverage purchased with a mortgage can begin at closing if the application is submitted by then. Federal flood insurance typically includes a 30-day waiting period.

Before closing, buyers can ask for the seller's current flood insurance declarations page.

That document lists the policy price, coverage limits, and deductibles, giving buyers a concrete insurance cost to weigh alongside the home's purchase price.

Where to learn more

Coverage gaps and repeated flood damage can add to the long-term cost of homeownership.

• In Florida, most homeowners insurance policies still do not cover flooding as hurricane season reaches its peak.
• Eligible Riverside County, California, residents could get 25% off flood insurance as El Niño approaches.
• In North Carolina, a gap in federal flood coverage pushed families back to washed-away lots.
