Florida Vacation Home: TCO Including Storm Risk

A $750,000 Florida vacation home does not cost $750,000 to own. It costs that, plus a homeowners insurance bill that Insurify pegged at an $8,292 statewide average for 2025 — the highest in the nation, projected to reach $8,458 by year-end 2026. Layer in a separate hurricane deductible structured as a percentage of dwelling coverage rather than a flat dollar figure, and the annual carrying cost of a Florida second home behaves less like a mortgage payment and more like a variable storm-risk premium that resets every renewal.

That insurance line is the variable most buyers underweight when they run the rent-versus-own math on a Gulf Coast condo or a Keys cottage. Mortgage and property tax are predictable. Storm exposure is not, and in Florida it dominates the vacation home net carry rate in a way it never does for a Colorado cabin or a Hamptons cottage.

The numbers at a glance

Five figures frame the Florida second-home decision more than any others. Each is drawn from a named source and dated below.

Building the annual TCO

Take a concrete case: a $750,000 single-family home in a Tampa Bay coastal zone, financed with 25% down on a 30-year second home mortgage. The financing premium alone separates this from a primary residence. Experian, citing Curinos data from April 2026, reports the average second home rate at 7.60% for a 720 FICO borrower against 6.71% for a comparable primary mortgage — a spread of roughly 0.9 points at the high end, though lender surveys put the typical gap at 0.25% to 0.75%. On a $562,500 loan, that premium adds several thousand dollars a year in interest before a single other cost lands.

Property tax, HOA or condo fees, and management commissions stack on top. For a property run as a short-term rental income property, the management fee runs 20–30% of gross rental revenue — a figure that scales with income rather than staying fixed. Maintenance on a coastal vacation property runs 1–2% of value annually, higher than inland norms because salt air, humidity, and storm wear accelerate roof and system replacement. Here is the stack for the Tampa Bay example, modeled as a rental property under the IRS mixed-use rules.

Property tax and utilities are segment estimates; model-specific data was unavailable, so figures are expressed as ranges where applicable.

The rental income offset, and why it disappoints

Florida markets do not all rent the same, and the spread is wide enough to change the entire ownership thesis. AirROI data covering April 2025 through March 2026 puts Orlando short-term rentals at $32,491 in average annual revenue, a 45.4% occupancy rate, and a $241 average daily rate. Kissimmee, the theme-park-adjacent market, runs hotter: a typical listing books 245 nights a year at a 67% median occupancy rate and a $188 average daily rate, generating about $46,000 in gross revenue per a separate AirDNA-affiliated dataset for the November 2024–October 2025 window.

Gross is not net. Strip out the 20–30% management commission, vacancy already baked into the occupancy figure, cleaning turnover, and platform service fees, and the net rental income that offsets ownership cost lands well below the headline. An Orlando property grossing $32,491 nets closer to $22,000–$24,000 after management and operating drag — and that assumes the owner accepts true rental-property tax treatment rather than tripping the personal-use threshold.

This is where the AirDNA headline number misleads. Most coverage cites gross revenue as if it offsets the mortgage dollar for dollar. AirDNA income potential versus real ownership cost diverges most sharply in high-insurance markets, because the same storm risk that inflates the premium also concentrates bookings into a few peak months and leaves the property exposed during hurricane season — precisely when carrying costs keep running.

The IRS 14-day rule changes the tax math

Personal use is not free. IRS Publication 527 classifies a property as a personal residence — not a rental — once personal use exceeds the greater of 14 days or 10% of the days it was rented at fair market value. Cross that line and deductible rental expenses get capped at rental income, eliminating the loss deductions that make the rental-property structure attractive in the first place.

Run the Orlando example at 200 rental days. The 10% test allows 20 personal-use days before reclassification; the 14-day floor is the binding constraint only at lower rental volumes. A family that spends three weeks at its own Florida home has converted an investment property into a second home in the eyes of the IRS, forfeiting the ability to deduct a net loss against other income. The IRS 14-day rule tax math for vacation properties is the single most expensive rounding error in second-home ownership — it is a binary cliff, not a sliding scale.

The Finluxy Vacation Home Net Carry Rate

Net carry rate strips the noise out. It expresses annual net carrying cost — total cost of ownership minus net rental income — as a percentage of purchase price, so a Tampa Bay condo and an Orlando house compare on the same axis regardless of price tag. Negative means the property pays for itself after all costs. Positive means it bleeds, and the number tells you how much.

Calculated using the Finluxy Vacation Home Net Carry Rate methodology (annual TCO minus net rental income, divided by purchase price). TCO inputs from Curinos via Experian (April 2026), FEMA Risk Rating 2.0 (2025), AirROI and AirDNA market data (2025–2026), and GreatFlorida premium ranges (2026). Income net of 25% management and vacancy. Figures are modeled estimates, not property-specific quotes.

Even the best-case Kissimmee scenario carries at over 5% of purchase price per year. The all-personal-use case approaches 11%. For comparison, the Cluster’s lake-house benchmark example carried at 4.2%. Florida’s storm-driven insurance load pushes the net carry rate materially higher than inland vacation markets, which is the quantitative case behind a softer intuition most buyers already have.

What the data shows that most coverage misses

The overlooked figure is not the premium — it is the deductible structure. Florida hurricane coverage carries a separate deductible calculated as a percentage of dwelling coverage, commonly 2%, 5%, or 10%, rather than the flat $1,000–$2,500 deductible most owners associate with home insurance. On a $750,000 home with $500,000 in dwelling coverage, a 5% hurricane deductible means $25,000 out of pocket before the policy pays a dollar on storm damage. A single named-storm claim can cost more than three years of premium savings from choosing the higher deductible.

This reframes the net carry rate as a floor, not a point estimate. The modeled 8.8% assumes no storm year. In a year with a deductible-triggering event, the true carry spikes by the deductible amount — a $25,000 swing that no rental income realistically offsets. Coverage that quotes the average premium and stops there is describing the calm-year cost of a risk that does not arrive on schedule.

Context for the $150k+ household

At $150k+ in household income, a Florida second home is affordable on a cash-flow basis and punishing on an opportunity-cost basis. The financing premium, documented by Curinos at 7.60% for second homes against 6.71% for primary residences as of April 2026, is the smallest of the differences; the second home mortgage rate premium adds a few thousand dollars annually, while insurance volatility and the storm deductible can swing the real cost by five figures in a bad year.

The decision threshold is whether the property functions as a lifestyle asset or an income asset, because the IRS will not let it be both without cost. A household that wants free use of its own home should price it as the ~10.7% net carry case and treat any rental income as incidental. A household optimizing for offset should commit to true rental treatment, cap personal use under the 14-day rule, and accept that even a well-run Kissimmee property carries above 5% of purchase price per year. Buyers weighing Florida against lower-insurance markets should run the same framework on a Colorado mountain home annual cost or a lake house year-round cost breakdown before assuming the warm-weather option is the cheaper carry — the storm premium frequently reverses that intuition. The broader second home cost guide for $150k+ buyers and a focused look at property management fees for second homes fill in the inputs this model treats as ranges. The cleanest financial outcome is the household that can absorb a $25,000 deductible year without it changing any other decision — for everyone else, the net carry rate is the number to underwrite against.
