Buying in the Florida Keys is different from buying on the mainland. Here are five things every Keys buyer needs to understand before they start shopping.
1. Flood Insurance Is Not Optional
Most Keys properties are in FEMA flood zones, and lenders require flood insurance. This can add $800-$5,000+ to your annual housing costs. Factor this in from the start, not at the closing table.
2. Condo Financing Has Extra Requirements
Not all Keys condos qualify for all loan types. FHA, VA, and conventional loans each have different project eligibility requirements. Check warrantability and approval status before making an offer.
3. Wind Insurance Matters
Windstorm and hurricane coverage are separate from standard homeowner insurance in the Keys. Wind premiums and hurricane deductibles can significantly affect your total monthly payment.
4. Many Properties Need Jumbo Financing
Waterfront homes and luxury properties frequently exceed the conforming loan limit of $832,750 for a one-unit property in most areas for 2026. Loan limits vary based on the number of units and whether the property is located in a designated high-cost area. If you are looking at properties above this threshold, jumbo loan qualification requirements are stricter.
5. Local Expertise Matters
A mainland mortgage professional may not understand Keys-specific challenges: condo warrantability, flood insurance pricing, wind mitigation discounts, and the impact of Keys construction codes on property values. Work with someone who knows the local market.
