Know the real number
before you make the offer.

Waterfront properties carry costs that inland properties don’t. Flood insurance, seawall maintenance reserves, dock insurance. The mortgage payment is only part of the monthly obligation.

Waterfront Carrying Costs · What Most Calculators Miss

Flood Insurance

Zone AE: $3,000–$12,000/year. Zone VE (oceanfront): $8,000–$40,000+/year. NFIP vs. private market rates vary significantly. Elevation certificate matters. This number can swing your monthly obligation by $500–$2,500.

Dock and Seawall Maintenance

Annual dock maintenance: $500–$2,000. Seawall inspection every 5 years: $500–$1,500. Seawall replacement (when needed): $150K–$450K. Budget a seawall reserve into your holding cost analysis — especially on anything over 25 years old.

Windstorm Insurance

Separate from flood. Palm Beach and Broward waterfront: $8,000–$30,000/year depending on construction, age, and proximity to coast. Citizens Insurance rates have shifted significantly post-Ian. Get a quote before you’re under contract, not after.
