DSCR Loan Rates for Florida Keys Vacation Rentals: What Investors Should Expect in 2026

If you are financing a vacation rental in the Florida Keys with a DSCR loan, the numbers that matter most in 2026 are the interest rate, your down payment, and what the property actually earns. This article looks at current DSCR rates and requirements for Keys investors and walks through the full cash flow picture so you can tell whether a deal makes sense.

DSCR stands for Debt Service Coverage Ratio, and a DSCR loan qualifies you on the property's projected rental income instead of your personal income. No W-2s, no tax returns, no pay stubs. Here I cover what rates look like right now, what it takes to get the best pricing, and the realistic income and expense side of a Keys rental that many investors only discover after they are under contract.

What Are DSCR Loan Rates in 2026?

DSCR loans are priced higher than conventional owner-occupied loans because the lender trades a full review of your personal income for a lower-documentation, rental-income qualification. In 2026, most Keys investors are seeing DSCR rates in a range of roughly 6.5 to 8 percent, depending on their profile.

• Strongest profiles (740+ credit, 25 percent down, DSCR of 1.25 or higher): low-to-mid 7 percent, with the best borrowers sometimes near 6.75 percent.
• Solid, typical profiles (660 to 720 credit, 20 percent down, DSCR around 1.0): roughly 7.25 to 7.75 percent.
• Minimum-credit or higher LTV profiles (620 credit, 15 percent down, lower DSCR): more often in the 8 percent range.

These are program-level ranges, and every lender prices differently, especially on Florida Keys properties that carry higher insurance costs and seasonal rental patterns. A rate quote is only meaningful alongside the full picture of the deal, which is why comparing offers from lenders who understand Keys vacation rentals matters so much.

What Determines Your DSCR Rate?

Lenders weigh several factors when they price a DSCR loan. The ones that move your rate the most are:

• Credit score. Higher scores unlock both lower rates and higher loan-to-value limits. Near top-tier credit (740+) is where pricing improves noticeably.
• Down payment and loan-to-value. A larger down payment means a lower LTV, and lower LTV generally earns better pricing. Some lenders also cap LTV at 75 percent for certain property types, which can push you to a larger down payment anyway.
• DSCR ratio. The stronger the projected income against the payment, the better the rate. A DSCR of 1.25 or higher typically qualifies for the best tier.
• Property type. Single-family homes and standard condos in the Keys are easier to place than mixed-use, multi-unit, or unusual properties.
• Rental income treatment. Whether the lender accepts short-term vacation rental income, and by how much it discounts that income, directly affects the DSCR your deal can show.

In the Keys, the combination of high purchase prices, heavy insurance, and reliance on seasonal short-term income means the DSCR ratio lenders will accept is a big part of the equation. Two nearly identical properties can qualify at very different rates depending on how those variables line up.

Current DSCR Loan Requirements for 2026

Here are the typical requirements Keys investors should plan around this year. These vary by lender, so think of them as a practical baseline rather than a guarantee.

Down Payment

Most DSCR programs want 20 to 25 percent down. The strongest borrowers (top credit, DSCR of 1.0 or higher) can sometimes qualify with 15 percent down at 85 percent LTV, but expect 20 percent as the starting point and 25 percent where a lender caps LTV at 75 percent, which is common for some Keys property types.

Credit Score

The minimum is generally 620, though some programs start at 640. For 80 percent LTV (20 percent down), most lenders want to see 660 or higher, and the best rates and maximum LTV usually call for 740 or better.

Minimum DSCR Ratio

A ratio of 1.0 is the common standard, meaning projected rent needs to at least cover the full housing payment. Some programs accept 0.75 with compensating factors like a larger down payment or a higher rate, and best-in-class pricing goes to deals at 1.25 or above.

Reserves

Plan for liquidity. Lenders typically require 3 to 12 months of mortgage payments in reserves after closing, and reserves tend to grow with the number of properties you already own.

Insurance

This is where Keys deals diverge from most mainland markets. You will carry flood insurance, windstorm insurance for coastal exposures, and standard hazard coverage. Every one of those premiums is folded into the total housing payment used to compute your DSCR, so higher insurance means you need stronger rental income to hold the same ratio. See flood insurance and wind insurance guides for the details.

What the 2026 Keys Vacation Rental Market Actually Looks Like

Realistic income assumptions matter more than headline numbers. The 2026 Florida Keys short-term rental market is best described as stabilizing, not booming. Occupancy is roughly flat to down a point in many areas while average daily rates climb modestly, which means total revenue is still holding up in places with strong demand.

• Monroe County vacation rental revenue grew about 8 percent year-over-year in recent months, with demand up more than 5 percent and supply flat, and short-term rentals account for roughly 70 percent of the county's tourist accommodations.
• Key West shows around 3,200 active short-term listings with occupancy near 60 percent and an average daily rate in the mid-$600s depending on the data source.
• Marathon shows a similar pattern, with roughly 60 to 68 percent occupancy and an average daily rate around $536.

What this means for underwriting is straightforward: a lender will look at the appraisal's rent schedule, not marketing headlines, and may discount short-term income by around 20 percent before it counts toward your DSCR. The seasonal reality of the Keys also means peak-season revenue carries a lot of the year, so annualize the numbers before you rely on a busy winter month to justify a loan.

The Full Cost Side of a Keys DSCR Deal

Your DSCR is only as accurate as your expense assumptions, and Keys expenses are heavier than most investors expect. Beyond principal and interest, build in:

• Flood insurance and wind insurance, which together can run in the tens of thousands per year on waterfront property.
• Property taxes, which in the Keys are meaningful relative to higher purchase prices.
• HOA or condo association fees, which lean on the higher side for amenity buildings and gated communities.
• Property management and cleaning fees if you use a short-term rental manager, plus utilities, turnover, and periodic maintenance.
• Vacancy and seasonality. A 60 percent occupancy keeps several months empty, and those months still carry mortgage and fixed costs.

When those are added to the payment, many "great on paper" rentals land below a 1.0 DSCR. That is not necessarily a dealbreaker, but it changes how much you put down and what rate you qualify for, so it should be part of the analysis from the start.

DSCR for Condos Versus Single-Family in the Keys

DSCR lending works for both single-family homes and condos in the Keys, but condos carry an extra layer. The loan goes through insurance, flood, and buyer-occupancy checks as well as a condo project review, and recent Florida structural and reserve requirements matter for whether a project qualifies at all. If you are considering a Keys condo as a rental, read the condo financing guide and confirm the project is on approved lists before you spend time on a rate conversation. A condo that cannot pass project approval will not close no matter how strong the numbers look.

How to Put Yourself in the Best Rate Tier

If a Keys rental deal is marginal on rate, these are the levers that help the most:

• Bring a larger down payment to lower the LTV, which both improves pricing and can satisfy lenders that cap LTV on certain property types.
• Buy a property with an existing, documented short-term rental history so the appraisal rent schedule is strong and defensible.
• Push your credit score into the 740-plus tier over a few months before you lock.
• Shop with lenders who actually underwrite Florida Keys vacation rentals and know how to treat short-term income, because a mainstream lender may discount it more aggressively or refuse it entirely.
• Get real insurance quotes from a Monroe County specialist before you underwrite, rather than estimating.

What to Ask a Lender Before You Apply

• What is your minimum DSCR, and what rate do I get at 1.0 versus 1.25?
• Do you accept short-term vacation rental income, and what haircut do you apply?
• What is the maximum loan-to-value for a Keys single-family and for a condo?
• What credit score do I need for your best rate tier?
• Which Keys properties and condo projects will and will not qualify?
• What reserves do you require after closing?

Getting clear answers before you commit keeps you from falling in love with a property that financing cannot support.
