Buying a Second Home in Florida 2026: Tax, Mortgage & Legal Guide

A Florida second home is not just a real estate purchase — it's a tax, mortgage, and legal decision with rules that differ significantly from your primary home. The IRS classification of your FL property, Florida's non-homestead tax treatment, and vacation rental regulations can each dramatically affect your cost of ownership.

Second Home vs. Investment Property: The IRS Classification That Changes Everything

Before you write an offer, you need to understand how the IRS — and your mortgage lender — will classify your Florida property. The distinction between "second home" and "investment property" affects your mortgage rate, your down payment requirement, your tax deductions, and your financing eligibility.

The §280A Rental Classification Rules — The 14-Day/10% Test

IRS §280A is the primary law governing how vacation property rental income and expenses are treated. The key thresholds:

• Rented 14 days or fewer per year: All rental income is completely tax-free. No deduction for rental expenses. Property is treated as purely personal for tax purposes regardless of rental activity.
• Rented more than 14 days AND personal use exceeds the greater of 14 days or 10% of rental days: Property is a "vacation home" — mixed use. You must allocate expenses between personal and rental use proportionally. Rental deductions are limited to rental income (no loss allowed).
• Rented more than 14 days AND personal use is less than 14 days AND less than 10% of rental days: Property is a rental/investment property — full rental deductions available, including depreciation, subject to passive activity rules.

Mortgage Financing for FL Second Homes

Down Payment: 10% Minimum

Fannie Mae and Freddie Mac permit second home mortgages with a minimum 10% down payment — higher than the 3%–5% available for primary residences, but much lower than investment property requirements (15–25%). The 10% minimum requires strong credit (typically 680+ FICO) and full income documentation. Some lenders set overlays requiring 15–20% down on second homes in certain FL coastal markets.

Rate Premium: Expect +0.5%–1.0% Above Primary Rates

Second home mortgages carry a pricing premium because default risk is higher — in a financial hardship, borrowers default on second homes before primary residences. In 2026, a borrower getting a 7.00% 30-year fixed on their primary home might pay 7.50%–8.00% on a second home mortgage. This premium applies even with perfect credit and 20% down.

Lender Classification Requirements

Lenders are strict about what qualifies as a second home vs. investment property for underwriting purposes. Common requirements to qualify as "second home" (vs. the less favorable investment property classification):

• At least 50 miles from your primary residence (common lender overlay — not a Fannie/Freddie rule, but widely applied)
• Suitable for year-round occupancy (not a seasonal or timeshare unit)
• No rental income arrangements in place at the time of loan application
• Borrower must maintain exclusive control over the property (no management company agreement at closing)
• Not subject to HOA or resort rental pool programs as a condition of ownership

Florida Property Tax: Non-Homestead Properties Pay More

Florida's property tax system provides significant protections for primary residents through the homestead exemption — but second home owners get none of these benefits.

The 10% Non-Homestead Cap vs. 3% SOH Cap

Florida Statute §193.1554 limits annual assessment increases for non-homestead residential properties to 10% — meaning if property values in a hot FL market rise 25% in a year (as happened in 2021–2022), the assessment on a second home can still rise up to 10%. On a homesteaded property, the cap is 3%. Over 5 years of 10% annual increases, a $600,000 assessed second home reaches $966,000 in assessed value — a 61% increase in the property tax base.

Florida DBPR Licensing for Vacation Rentals

Under Florida law (FL Stat. §509.242 and the Florida DBPR Division of Hotels and Restaurants), any residential property rented for periods of less than 30 days more than three times per year is classified as a "vacation rental" and requires a license from the Florida Department of Business and Professional Regulation (DBPR). The license application involves:

• Registration as a vacation rental (transient public lodging establishment)
• Payment of annual license fee ($50–$300 depending on property type)
• Compliance with safety requirements (smoke detectors, fire extinguishers, pool fencing per FL Stat. §515.27)
• Registration for Florida Transient Rental Tax (6% state + county TDT, which can bring total to 10–13%)

County and HOA Short-Term Rental Restrictions

Florida gives counties and municipalities authority to regulate vacation rentals at the local level, and HOAs can impose additional restrictions. The STR landscape in FL varies dramatically by location:

• Destin/Walton County (30A): Active STR market; county regulates but does not ban; HOAs in some communities prohibit rentals under 30 days
• Kissimmee/Osceola County: Very STR-friendly; vacation home communities specifically designed for STR; Disney proximity drives strong rental demand
• Miami-Dade: City ordinances vary significantly by municipality; Miami Beach has minimum 30-day rental restrictions in some areas
• Naples/Collier County: Community-level restrictions are common; many luxury communities prohibit STR; verify HOA documents before purchase
• Florida Keys/Monroe County: Complex STR rules; rental cap programs in some areas; verify with county before assuming rental income

Capital Gains: The §121 Exclusion Does Not Apply

When you sell your primary residence, IRS §121 allows you to exclude up to $250,000 of capital gain ($500,000 married filing jointly) from federal income tax — if you've lived in the home for at least 2 of the past 5 years. This exclusion is not available for a property you never lived in as your primary residence (a true second home or vacation property).

For a FL second home, when you sell:

• All capital gain is taxable — federal long-term capital gains rates (0%, 15%, or 20% depending on income)
• Net Investment Income Tax (NIIT) of 3.8% may apply for high-income taxpayers (income above $200K single/$250K married)
• Florida has no state capital gains tax (no state income tax)
• Depreciation recapture at 25% applies to any depreciation you claimed while the property was rented
• The §1031 exchange is available for investment property but not for a pure second home — the property must have been held for investment or business use

FIRPTA: What FL Second Home Buyers Need to Know About Foreign Sellers

The Foreign Investment in Real Property Tax Act (FIRPTA, IRC §897) requires buyers to withhold 15% of the gross purchase price when buying from a foreign person or entity. In Florida's second home markets — especially coastal areas with significant foreign buyer ownership — this is a practical concern.

Key FIRPTA considerations for FL second home buyers:

• Buyer is the withholding agent — you are responsible for withholding even if your agent or title company fails to flag it
• 15% withholding on gross sales price (not net gain) — significant on high-value FL properties
• Reduced withholding (10%) available if the buyer will use the property as a primary or secondary residence AND the purchase price is $1M or less
• Withholding is remitted to IRS within 20 days of closing
• FL title companies routinely handle FIRPTA withholding on international seller transactions

The Snowbird Domicile Trap

Thousands of northern retirees and executives purchase Florida second homes to take advantage of the state's no-income-tax status. The trap: simply owning a FL property does not make you a Florida resident for tax purposes. Your prior state may continue to claim you as a resident — and tax your worldwide income — unless you properly establish Florida domicile.

To establish Florida domicile and defeat a high-tax state's residency claim:

• File a Florida Declaration of Domicile with the county clerk (FL Stat. §222.17)
• Obtain a Florida driver's license and register vehicles in FL
• Register to vote in Florida
• Spend more than 183 days per year in Florida (keep records — calendar, credit card statements, travel logs)
• Change professional registrations, banking, and mailing addresses to FL
• Update estate planning documents (will, trust) to reflect FL domicile
• File final part-year tax return in the old state; file FL residents' tax documents if required

States like New York, California, Massachusetts, and New Jersey aggressively audit claimed domicile changes, particularly for high earners. They look at where you spend your time, where your family is, where your social and professional ties are, and where your primary home is. The consequences of failing a domicile audit: the state taxes your income for every year you claimed FL residency.

Insurance for FL Second Homes

Insurance for FL second homes is more expensive and more complex than for primary residences — in part because insurers know that vacant or part-time-occupied homes carry higher claim risk.

• Vacancy clauses: Standard homeowners policies may limit coverage if the home is unoccupied for more than 30–60 days. Second homes require a policy that explicitly covers extended vacancy.
• Named-storm deductibles: FL coastal second homes face hurricane deductibles of 1%–10% of insured value — often $10,000–$50,000 or more — rather than a flat dollar deductible
• Flood insurance: Required by lenders on properties in FEMA flood zones; FL's NFIP participation is among the highest in the country. Second homes in flood zones may not qualify for preferred rates under NFIP if not owner-occupied
• Vacation rental coverage: Standard homeowners policies typically exclude coverage for claims arising during rental periods. If you rent your FL second home, you need a separate vacation rental insurance rider or a dedicated vacation rental policy
• Wind insurance (Citizens or private market): Many FL coastal counties require separate wind insurance. Second homes may face higher wind premiums than primary residences with the same coverage
