Closing Costs in the Florida Keys: What Homebuyers Need to Know

If you are buying a home in the Florida Keys, you have probably saved up for a down payment and have a good sense of what your monthly mortgage payment will look like. But there is another number that catches many Keys buyers off guard: closing costs. In the Keys, those costs run higher than in most of Florida, and the difference comes down to one thing above all else — insurance.

This guide breaks down exactly what closing costs you can expect when buying a home in the Florida Keys, why they are higher here than on the mainland, and how to budget accurately so there are no surprises when you sit down to close.

How Much Are Closing Costs in the Florida Keys?

For a typical home purchase in Monroe County, closing costs generally run between 2 and 5 percent of the purchase price. With the median home value in the Keys hovering around $961,000 as of mid-2026, that means you should budget roughly $19,000 to $48,000 in closing costs on top of your down payment.

That range is wide because every transaction is different. Your actual closing costs depend on your loan amount, loan type, the property's location and insurance requirements, and whether the seller contributes to your closing costs as part of the negotiation.

The Keys push toward the higher end of that range because of insurance prepaids, which are significantly more expensive here than anywhere else in Florida. A buyer in inland Orlando might prepay $2,000 in insurance at closing. A buyer in the Keys, depending on the property, can easily prepay $5,000 to $15,000 or more.

Breaking Down the Major Closing Costs

Let me walk through each cost category so you know exactly what to expect on your Loan Estimate and Closing Disclosure.

Lender Fees and Origination Charges

These are the fees your lender charges to process, underwrite, and fund your loan. They typically include:

• Loan origination fee: Usually 0.5 to 1.5 percent of the loan amount. On a $700,000 loan, that is $3,500 to $10,500.
• Appraisal fee: $400 to $700. A standard appraisal for a Keys single-family home. Complex waterfront properties may cost more.
• Credit report fee: About $50.
• Flood zone determination fee: $15 to $25. A basic check to confirm whether the property is in a FEMA-designated flood zone. In the Keys, nearly every property is.
• Tax service fee: $50 to $100. Your lender uses this service to verify that property taxes are paid.

These fees vary by lender, so it is always worth comparing loan estimates from two or three lenders before committing. Even small differences in origination fees add up when you are financing a high-value Keys property.

Taxes and Government Fees

Florida imposes two mortgage-related taxes that appear in your closing costs:

• Mortgage Documentary Stamp Tax: $0.35 per $100 of the loan amount (roughly 0.35 percent of the loan). On a $700,000 loan, that is about $2,450. This is a buyer cost in Monroe County.
• Intangible Tax on Mortgage: 0.2 percent of the total loan amount. On a $700,000 loan, that is about $1,400.
• Recording fees (Monroe County): $10 for the first page, $8.50 for each additional page. Expect $100 to $200 total for recording the deed and mortgage.

The Documentary Stamp Tax on the Deed (transfer tax of $0.70 per $100 of the sale price) is paid by the seller in Monroe County, following the common Florida custom outside Miami-Dade. That is roughly $6,700 on a $961,000 sale, but it is not your cost as the buyer.

Title Insurance and Settlement Fees

Title insurance protects you and your lender against claims or liens on the property that were not discovered during the title search. In the Keys, these costs follow Florida's promulgated rate structure:

• Lender's title insurance: Required by your lender. Approximately $500 for the first $100,000 of the loan amount, then $5.75 per additional $1,000. On a $700,000 loan, roughly $3,950.
• Owner's title insurance: Optional but strongly recommended. In Monroe County, the seller typically pays for the owner's policy as part of the sale. If you pay, it follows a similar rate structure: $5.75 per $1,000 on the first $100,000 of the purchase price, then $5.00 per $1,000 above that. On a $961,000 home, that is about $4,880.
• Settlement/closing fee: $500 to $800 paid to the title company or closing attorney for conducting the closing.
• Title search and exam: $100 to $300.

Insurance Prepaids: The Big Differentiator

This is where the Florida Keys separates from the rest of Florida. Keys properties typically require three separate insurance policies, and lenders require you to prepay a portion of the premiums at closing:

• Homeowners/dwelling insurance: $3,000 to $5,000 per year
• Windstorm/hurricane insurance: $8,000 to $12,000 per year
• Flood insurance (NFIP or private): $2,200 to $5,000 per year
• Combined annual total: $13,000 to $22,000 per year

At closing, your lender typically requires you to prepay the full first year's premium for the hazard/wind policy and the flood policy, plus put 2 to 3 months of premiums into your escrow account. Depending on where your closing date falls in the policy cycle, prepaid insurance at closing can run $3,250 to $22,000.

This is the single largest source of closing cost variation between the Keys and the rest of Florida. A buyer in inland Florida might prepay $1,500 to $2,500 in insurance at closing. A Keys buyer can easily prepay five to ten times that amount.

For a deeper look at these costs, see the full guides on flood insurance and wind insurance in the Keys.

Property Tax Prepaids

Lenders also collect property tax prepaids at closing. In Monroe County, property taxes are paid in arrears (you pay for the previous year), so at closing you reimburse the seller for the portion of the tax year they already paid for but will not live in the home to use. You will also fund 2 to 6 months of property taxes into your escrow account, depending on when you close and your lender's requirements.

On a $961,000 home in Monroe County, annual property taxes typically run $8,000 to $12,000 depending on the exact location and whether the property has a homestead exemption. At closing, expect to prepay $2,000 to $6,000 in property taxes depending on the timing.

Survey, Inspection, and Other Due Diligence Costs

These are costs you pay during the due diligence period, before closing, but they are part of the total cash you need to bring to the transaction:

• Home inspection: $400 to $700 for a standard inspection. Specialty inspections (septic, mold, pool, termite) add more.
• Survey: $500 to $1,200. Waterfront and canal-front lots can push toward the higher end due to access challenges.
• Elevation certificate: $185 to $350. If the seller does not already have one, you will need this for flood insurance pricing. It documents the elevation of the lowest floor relative to the Base Flood Elevation.

Also budget for your earnest money deposit, typically 1 to 3 percent of the purchase price, which is held in escrow and credited toward your down payment and closing costs at closing. On a $961,000 home that is $9,600 to $28,800, but this is not a closing cost per se because it goes toward your total cash due at the table.

A Real-World Closing Cost Example

Let me put this in concrete terms. Here is what closing costs might look like on a $900,000 home in Marathon with a $720,000 conventional loan (20 percent down) in mid-2026:

In this example, insurance prepaids alone total nearly $17,000, or about 47 percent of all closing costs. That is the Keys reality. On the same-priced home in inland Florida, insurance prepaids might be $3,000, and total closing costs might be $22,000 to $25,000.

This is also why the common online advice that closing costs are "3 to 5 percent of the purchase price" understates the cash you need in the Keys. On a $900,000 home, 3 percent is $27,000. In this real-world example, you are looking at closer to 4 percent, and some Keys transactions push toward 5 percent because of insurance costs.

How Loan Type Affects Closing Costs

Different loan programs come with different cost structures. Here is how they compare for Keys buyers:

Conventional Loans

Standard closing cost structure as outlined above. If your down payment is less than 20 percent, you will pay private mortgage insurance (PMI), which adds to your monthly payment but not to your upfront closing costs in most cases (the mortgage insurance premium is paid monthly, not as a single upfront fee).

FHA Loans

FHA loans require an upfront mortgage insurance premium (UFMIP) of 1.75 percent of the loan amount, which is typically rolled into the loan rather than paid at closing. This adds to your total loan balance rather than your upfront cash requirement. FHA also allows a higher seller contribution toward closing costs (up to 6 percent of the purchase price), which can reduce your cash to close.

VA Loans

VA loans have a funding fee (0.5 to 3.3 percent depending on down payment and whether it is a first or subsequent use) that can be rolled into the loan. VA loans also prohibit the borrower from paying certain lender fees, which modestly reduces closing costs. And VA loans do not require PMI, which saves on monthly payment.

Jumbo Loans

Jumbo loans often carry slightly higher origination fees and require more reserves, which means you need more cash on hand. However, the mortgage documentary stamp and intangible taxes still apply at the same rates, so the percentage-based costs scale with the higher loan amount.

Can You Reduce Your Closing Costs?

Yes, but with some important caveats in the Keys. Here are the main strategies:

Negotiate a Seller Credit

In Monroe County, it is common for the seller to contribute toward the buyer's closing costs. Conventional and FHA loans allow seller contributions up to 3 to 6 percent of the purchase price depending on the down payment. VA loans allow up to 4 percent. A 3 percent seller contribution on a $900,000 home is $27,000, which could cover the majority of your closing costs.

This is one of the most important negotiation points for Keys buyers. If you are putting 20 percent down and your closing costs are $36,000, asking the seller to cover $27,000 of that brings your cash to close down significantly. Seller credits are especially common in the Keys when the home has been on the market for a while or needs updates.

Shop for Lower Lender Fees

Origination fees vary by lender. Getting multiple loan estimates and comparing the origination charge, processing fee, and underwriting fee can save you $1,000 to $3,000. Just be careful not to choose a lender solely on low fees if they do not understand Keys-specific issues like insurance escrows, flood zone requirements, and Keys appraisal dynamics.

Ask About Lender Credits

You can accept a higher interest rate in exchange for a lender credit that covers some or all of your closing costs. This is called a "par-plus" or "yield spread premium" transaction. If you plan to stay in the home for a short time (under 5 years), this can make sense because you will not pay the higher rate long enough for it to cost more than the upfront credit saves you. If you plan to stay longer, paying points to buy down the rate is usually the better financial decision.

What You Cannot Reduce

Some closing costs are fixed and not negotiable. Insurance prepaids are set by the insurance market, not by your lender or the seller. Government taxes (documentary stamp, intangible tax) are set by state law. Recording fees are set by Monroe County. Title insurance follows Florida's promulgated rate schedule. So while lender fees, points, and seller credits are flexible, the insurance and tax components that make Keys closing costs unique are largely fixed.

Closing Costs for Condos in the Keys

If you are buying a condominium in Key West, Marathon, or elsewhere in the Keys, your closing costs will be slightly different:

• Lower insurance prepaids: The HOA carries the master wind and flood insurance policies for the building structure. Your individual prepaids cover only your contents and interior upgrades. Expect roughly $1,500 to $3,500 in total annual insurance for condo unit coverage versus $13,000 to $22,000 for a single-family home.
• HOA due diligence: You may need to pay for the condo questionnaire and document review ($100 to $300), which the lender uses to verify the project meets financing requirements.
• No separate survey typically needed: Condos within a single building usually do not require a new survey.
• No wind-only policy needed: The HOA's master policy typically covers the building envelope against wind damage.

Overall, closing costs for a condo in the Keys are lower than for a single-family home, primarily because insurance prepaids are dramatically less. See the condo financing guide for more detail on how condo purchases differ from single-family home purchases.

Closing Costs by Location in the Keys

While the fee structure is largely the same across Monroe County, the dollar amount of closing costs varies with purchase price. Here is what typical closing costs look like in different Keys markets (assuming 20 percent down and conventional financing, including full insurance prepaids):

• Key Largo (median ~$925,000): Closing costs $32,000 to $42,000
• Islamorada (median ~$1.15M): Closing costs $38,000 to $52,000
• Marathon (median ~$950,000): Closing costs $34,000 to $45,000
• Key West (median ~$1.25M): Closing costs $42,000 to $58,000
• Big Pine Key (median ~$700,000): Closing costs $25,000 to $35,000

These ranges assume full insurance prepaids. Condos in any of these locations will have significantly lower totals due to reduced insurance costs.

How to Prepare for Closing Costs as a Keys Buyer

Here is what I recommend every Keys buyer do before writing an offer:

Closing Costs for Second Homes and Investment Properties

If you are buying a second home or investment property in the Keys, expect higher closing costs than a primary residence purchase. Lenders typically charge higher origination fees for non-owner-occupied properties, and the insurance costs are the same or higher. Additionally, the annual increase cap for flood insurance on second homes is 25 percent versus 18 percent for primary residences under FEMA's Risk Rating 2.0, which means prepaids may be based on a higher starting premium for a property that has been held as a second home for several years.

For DSCR loans on vacation rentals, some closing costs can be slightly higher because DSCR lenders often charge a premium for the product. But the insurance prepaids follow the same structure: full payment of the first year's hazard, wind, and flood premiums at closing.

The Bottom Line on Keys Closing Costs

• Budget 2 to 5 percent of the purchase price for closing costs, and expect to land closer to 4 to 5 percent if you are buying a single-family home that requires full insurance coverage
• Insurance prepaids are the biggest differentiator between the Keys and the rest of Florida, often accounting for 40 to 50 percent of total closing costs
• A seller credit of 3 percent of the purchase price can cover most or all of your closing costs in many Keys transactions
• Condo purchases have significantly lower closing costs because the HOA carries the building-level insurance
• Get an early insurance quote and a lender cost estimate before you start making offers, so the closing cost number is never a surprise
