How Much Does It Cost to Sell a House in Key West, Florida?

This is the question I get more than almost any other from sellers who are seriously thinking about listing. The honest answer is: more than you might expect — especially in Key West, where the transaction costs carry some line items you won't see on a mainland Florida net sheet.

Let me walk you through exactly what comes off the top, with real numbers for the Key West market.

What Monroe County Sellers Pay at Closing

Florida real estate transactions have a clear division of who pays what, and Key West follows the standard Monroe County conventions. Here are the costs that fall to the seller:

Documentary Stamp Tax on the Deed

Florida charges a transfer tax called the documentary stamp tax — "doc stamps" — every time a deed changes hands. In Monroe County, the rate is $0.70 per $100 of the sale price, paid by the seller.

On a $1,500,000 sale: $10,500. On a $2,000,000 sale: $14,000. This is non-negotiable — the state sets the rate, and it's collected at closing by your attorney or title company and remitted to the Florida Department of Revenue.

Owner's Title Insurance

In Monroe County, it's customary for the seller to pay for the owner's title insurance policy that protects the buyer. Florida uses promulgated rates set by statute, so every title company charges the same: $5.75 per $1,000 of coverage for the first $100,000, then $5.00 per $1,000 above that.

On a $1,500,000 sale, the owner's title insurance runs approximately $7,575. On a $2,000,000 sale, it's around $10,075.

Real Estate Commissions

This is typically your largest line item. Commission structures evolved after the 2024 NAR settlement — buyers now negotiate compensation with their agent directly — but in practice, most sellers in Key West still offer buyer's agent compensation to attract the broadest pool of qualified buyers.

Total commission in a Key West transaction typically runs 5% to 5.5% of the sale price, negotiated with your listing agent. On a $1,500,000 sale, that's $75,000–$82,500. It's worth having a direct conversation with your broker about how commission is structured before you sign a listing agreement.

Closing Attorney Fees and Title Charges

Key West closings are typically handled by a local real estate attorney who serves as the closing agent and holds escrow — not a national title company. Attorney fees for a standard residential closing run $750–$1,500 flat, plus a title search fee of $200–$300 and recording fees of roughly $100–$200. These are modest costs on a high-value transaction.

Prorated Property Taxes

Florida property taxes are paid in arrears. If you sell before the end of the year, you'll owe the buyer a credit for the portion of the year you owned the home. On a $1,500,000 Key West property where the annual tax bill runs approximately $15,000, a June closing means roughly $7,500 credited to the buyer at closing.

One important note: the buyer's tax bill resets to current market value when the sale closes. If you've been in your home for years and benefiting from Florida's Save Our Homes assessment cap, the buyer loses that cap — their taxes start over at the new purchase price. For buyers who don't qualify for Florida's homestead exemption (vacation home and second home buyers, who represent most of Jimmy's buyer clients), there's no cap protection at all.

A Sample Net Sheet: $1,500,000 Key West Home

• Sale price: $1,500,000
• Documentary stamp tax (0.70%): −$10,500
• Owner's title insurance: −$7,575
• Real estate commissions (5.5%): −$82,500
• Attorney closing fee + title search: −$1,500
• Recording fees: −$150
• Prorated property taxes (mid-year): −$7,500
• Estimated gross proceeds before mortgage payoff: ~$1,390,775

That's a total selling cost of roughly $109,225 — about 7.3% of the sale price, before your mortgage payoff. If your mortgage balance is $600,000, your net cash at closing is approximately $790,000.

Every situation is different. HOA estoppel certificates, open permits, repair concessions, and buyer closing cost credits all move the number. The only way to know your real number is to run a personalized net sheet for your specific property.

What Makes Key West Different from the Mainland

The cost structure above is broadly consistent with Florida — but Key West has a few layers that don't show up on a generic Florida seller's checklist.

Insurance Costs Are Reshaping Your Buyer Pool

This is the single biggest factor driving Key West's current market dynamics. A December 2025 headline from Key West Island News put it plainly: soaring insurance costs are pushing buyers out of the market.

Annual insurance premiums on a Key West home — combining wind, flood, and hazard (homeowners) coverage — routinely run $15,000–$30,000+ on a luxury property. That's a second mortgage payment for many buyers. It affects how they underwrite their offer, how much they're willing to pay for your home, and how long it takes to find a buyer who can absorb those carrying costs.

Homes in Key West were averaging 221 days on market in early 2026 and selling for approximately 6% below list price on average. Sellers who price with the buyer's total ownership cost in mind — not just the sale price — are moving their homes. Sellers who don't are sitting.

If your property sits in an AE flood zone, a VE zone, or anywhere below base flood elevation (BFE), insurance costs are part of your pricing conversation. Elevation certificates, existing assumable flood policies, and wind mitigation features all affect what a buyer will pay — and what they can afford. For more on how your property's flood zone affects your transaction, see Jimmy's guide to Key West real estate investment analysis.

The Florida Flood Disclosure Requirement

Since October 1, 2024, Florida law requires sellers to provide a standalone Flood Disclosure Form to buyers at or before the contract is signed. This is separate from the standard Seller's Property Disclosure form.

You'll need to disclose whether you've ever filed a flood insurance claim or received federal assistance for flood damage to the property. In Key West, where nearly every property sits in a FEMA flood zone (AE, X, or VE), this disclosure is not optional and failing to provide it can jeopardize your contract.

Your listing broker should have this form ready before you go to market.

Transient Rental Licenses: The Asset That Changes Your Sale

If your property carries a City of Key West transient rental license — allowing nightly or weekly rentals — you need to understand that this license has substantial independent value. The City has not issued new transient licenses in years. Secondary market transactions for licenses alone have reached $300,000–$400,000.

How you disclose, price, and market a transient-licensed property is fundamentally different from a property without one. The presence of a license expands your buyer pool to include investors and vacation rental operators who will pay a significant premium. Getting the pricing strategy right on a licensed property is where working with a local broker who knows this market becomes essential.

The Monroe County Enclosure Rule Change

In October 2025, Monroe County eliminated the pre-transfer inspection requirement for downstairs enclosures beneath elevated homes. Previously, sellers had to obtain a floodplain compliance certificate before closing if their home had a ground-level storage enclosure — a step that delayed and occasionally killed transactions. That requirement is gone. If your home has a downstairs enclosure, one friction point in your sale just went away.

Frequently Asked Questions

Who pays closing costs when selling a home in Key West, Florida?

In Monroe County, the seller customarily pays the documentary stamp tax on the deed ($0.70 per $100 of the sale price), the owner's title insurance policy, the title search fee, recording fees, and any outstanding liens. Buyers typically pay their own lender-required fees and the documentary stamp tax on their mortgage. Real estate commissions are paid by the seller at closing and split between agents as negotiated.

How much is the documentary stamp tax when selling a home in Monroe County?

Florida's documentary stamp tax in Monroe County is $0.70 for every $100 of the sale price. On a $1,500,000 Key West home, that's $10,500 paid by the seller at closing. Miami-Dade County uses a different rate, but Monroe County follows the standard Florida rate of $0.70 per $100.

Do I need a real estate attorney to sell my house in Key West?

Florida does not legally require a real estate attorney for a residential closing, but using one is strongly recommended in Key West. A local attorney serves as the closing agent, holds escrow, handles the deed transfer, and ensures all title issues are resolved. Attorney closing fees for a residential transaction typically run $750–$1,500 flat — a modest cost on a high-value transaction. Jimmy's team works with a trusted local Key West attorney on every closing.

How does Florida's flood disclosure law affect home sellers in Key West?

Since October 1, 2024, Florida law (Statute § 689.302) requires sellers to provide a separate, standalone Flood Disclosure Form to buyers at or before the contract is signed. Sellers must disclose whether they have ever filed a flood insurance claim or received federal flood assistance. In Key West, where nearly all properties are in FEMA flood zones AE or VE, this disclosure is a standard part of every transaction — and failing to provide it can void a contract.

How do high insurance costs in Key West affect my sale price as a seller?

Insurance costs directly affect who can afford to buy your home and how long it takes to sell. Annual insurance premiums in Key West — combining wind, flood, and hazard coverage — often run $15,000–$30,000 or more on a luxury property. Buyers factor these carrying costs into their offer math, which is one reason homes in Key West were averaging 221 days on market in early 2026. Pricing your home to reflect the buyer's total ownership cost — not just the sale price — is critical in this market.

Selling a home in Key West involves more moving pieces than a typical Florida transaction. The line items above are consistent, but the number that matters — your actual net — depends on your property's specific flood zone, insurance situation, rental licensing status, current condition, and how the market prices your home against its carrying costs.
