DSCR Loan Refinance in the Florida Keys: A Guide for Vacation Rental Investors

If you already own a vacation rental in the Florida Keys and equity is sitting in the property, a DSCR refinance may be the most practical way to get cash out, trade a hard-money loan for permanent financing, or change the terms without using your personal income to qualify. A DSCR loan is underwritten on the rental income the property produces rather than your W-2s and tax returns, and that same qualification method applies when you refinance. This guide covers cash-out and rate-and-term DSCR refinances, the seasoning and delayed-financing rules, and whether refinancing makes sense for your situation in late 2026.

If you are new to the program, my DSCR loans for vacation rentals guide covers how the loan works from the ground up, my DSCR rate guide walks through current pricing, and my short-term rental income guide explains how lenders calculate what a property can earn. This article goes a step further and looks at the refinance side: when you can refinance, how much you can take out, and the rules that catch most Keys investors by surprise.

What Is a DSCR Refinance, and Why Do Keys Investors Use It?

A DSCR refinance replaces the existing loan on a rental property with a new DSCR loan, using the property's projected rental income as the basis for qualification instead of your personal income. The formula is the same one I covered in depth in the income guide: DSCR = monthly gross rental income divided by the total monthly housing payment, where the payment includes principal, interest, taxes, insurance, and HOA dues. When the income side covers the payment side at the lender's required ratio, you qualify.

In the Florida Keys, investors refinance rentals into DSCR loans for three main reasons:

• To pull equity out. A cash-out DSCR refinance turns years of appreciation in properties like Key Largo or Islamorada into cash you can put toward another purchase or another use.
• To move off short-term financing. Hard-money, bridge, or private-money loans carry high rates and short terms. A DSCR refinance pays them off with a longer-term loan while the rental income supports the payment.
• To change terms without cash. A rate-and-term refinance adjusts your rate or term when your situation calls for it, with no cash back at closing.

The qualification advantage is the same as on a purchase: no W-2s, no tax returns, no pay stubs. The property's income carries the deal. That is exactly why self-employed investors and owners with complicated tax returns lean on DSCR refinancing in the Keys.

Cash-Out Refinance: How Much Equity Can You Take?

Cash-out refinancing is the most common DSCR refinance in the Keys, and the loan-to-value limits are the first thing to understand. On a short-term vacation rental, most DSCR lenders cap a cash-out refinance at roughly 70 to 75 percent loan-to-value, and several programs are stricter on refinance than on purchase, where 75 to 80 percent is more common. On a $1.5 million Keys rental, 70 percent LTV means you can carry a loan of about $1.05 million, leaving $450,000 in equity. If you want more than that out, you typically cannot get it with this program.

Beyond the LTV cap, the typical cash-out requirements on a Keys vacation rental refinance look like this, and they vary by lender:

• Credit score: minimums usually start near 640, with 660 or higher more common on refinance programs.
• DSCR floor: the property's discounted income must still clear the lender's coverage minimum, most often 1.00 on a refinance.
• Income discount: short-term rental income is typically discounted around 20 percent before it counts, so the appraised or documented income has to carry real weight.
• Rental history: many lenders want roughly 12 months of hosting history on the property, or a solid appraisal-based rent projection for a newer rental.
• Reserves: plan for about 2 to 6 months of principal, interest, taxes, insurance, and HOA payments in reserve after closing.

Insurance is where Keys deals differ from the mainland. Flood and wind premiums are folded into the total housing payment used to compute your DSCR, so a waterfront rental with heavy premiums needs stronger income to hold the same ratio. My flood insurance and wind insurance guides give you a realistic sense of those costs before you run the numbers.

Rate-and-Term Refinance: No Cash, Different Loan

A rate-and-term DSCR refinance pays off the existing loan and its costs with no cash back to you. Its purpose is a better interest rate, a different term, or switching a loan structure you no longer want. Because there is no cash-out, lenders generally allow a higher loan-to-value, in some programs up to roughly 85 percent, and seasoning requirements are usually much lighter, often none to 3 months of ownership. The property still has to clear the lender's coverage floor, typically a DSCR of 1.00.

The honest math in late 2026: the 30-year fixed is near 7.40 percent, the highest level in nearly three years by the October reading, and DSCR pricing sits above owner-occupied conventional rates on top of that. For most Keys investors, a rate-and-term DSCR refinance is not going to lower your payment right now if your current loan is already a DSCR. Where it earns its keep today is moving out of a hard-money or portfolio loan with a double-digit rate, exiting an ARM or a balloon you do not want to ride out, or switching from a loan with a prepayment structure you dislike. My refinance program page covers the rate-and-term versus cash-out distinction in more detail.

Seasoning: How Long Before You Can Refinance?

Seasoning is the rule that surprises the most Keys investors, and it is different for cash-out than for rate-and-term. On a finance purchase, a cash-out refinance commonly requires about 6 months of ownership from the recorded deed date before you can refinance, with some lenders at 3 months and others closer to 12. Inside that window, most lenders value the property at the lower of your documented cost plus capital improvements or the appraised value, which removes the temptation to buy, inflate value, and cash out immediately.

If you purchased the rental with all cash in an arm's length deal, you have a better option: delayed financing. Most DSCR programs let you refinance that property and take cash out right away, as long as the new loan amount does not exceed the documented purchase price plus closing costs and documented improvements. That means an all-cash buyer does not always need to wait out a seasoning period to recover equity.

A rate-and-term refinance, by contrast, generally needs little or no seasoning because you are not taking cash out and the risk to the lender is lower. If your goal is purely a rate or term change, that is often the fastest path.

Refinancing an Existing Conventional or Hard-Money Loan Into DSCR

Yes, a DSCR loan can refinance a rental regardless of how it was originally financed. The loan is underwritten on the property's rental income, not on how the current mortgage was originated, so an existing conventional mortgage, a hard-money loan, a bridge loan, or even another DSCR loan can be paid off and replaced. The new loan simply covers the payoff, and if you meet the LTV, seasoning, credit, and coverage requirements, you can take cash out on top of the payoff.

The main considerations are the ones I mentioned above: the cash-out LTV cap on a short-term rental, the seasoning window if you financed the purchase rather than paying cash, and reserves. There is one more to check before you commit: prepayment penalties. Some DSCR loans carry a prepayment penalty of 1 to 2 percent of the loan amount or more if you pay them off early, often within the first 2 to 3 years. If you are refinancing an existing DSCR loan, have your current lender quote the penalty before you count the savings, because on a $1 million loan even 1 percent is $10,000.

It is also worth asking whether a DSCR refinance is the right product at all. If your income is easy to document, a conventional investment property refinance may price well below a DSCR loan, and my investment property and vacation home pages explain those options. DSCR makes sense when the property's income is the cleaner path to qualification, even at a higher rate.

When a DSCR Refinance Makes Sense in the Keys Right Now

In the current rate environment, the strongest reasons to refinance a Keys vacation rental into a DSCR loan are equity extraction and moving off expensive short-term financing, not shaving a quarter point. If your rental has appreciated substantially, a cash-out DSCR refinance can fund your next purchase, consolidate debt, or cover insurance-heavy expenses without selling. If you bought with hard money to close fast during a busy buying season, a DSCR refinance turns that costly short-term loan into a permanent, interest-only or amortizing loan that the rental income supports.

A few Keys-specific realities shape whether the deal works:

• High-value deals are usually jumbo. Monroe County's conforming limit is $990,150 and many Keys rentals exceed it, so the refinance often needs a jumbo DSCR lender. My jumbo loan page explains how those programs work.
• Condos carry an extra layer. A DSCR refinance on a Keys condo goes through the same project review, structural, and reserve checks as a purchase. Confirm the project qualifies before you spend time on a rate conversation, and see the condo financing guide for the requirements.
• The appraisal is the crux. On a refinance there is no purchase contract to anchor value, so the appraiser's opinion of value and market rent carries the whole deal, and waterfront, canal, and dock features are valued by genuinely comparable sales. That is why the same underwriting care I describe in my Keys appraisal guide matters so much here.
• Local rental rules matter. DSCR underwriting assumes the property can legally be rented the way you plan, and short-term rental rules vary across Marathon, Key West, and the island communities in between, so confirm your rental status is current before you refinance around a specific occupancy number.

If you are comparing a cash-out DSCR refinance against a HELOC on an owned-free-and-clear rental, the HELOC page covers the trade-offs: a HELOC keeps your existing mortgage untouched and gives you a revolving line, while a DSCR cash-out consolidates everything into one payment at a fixed or adjustable rate. The right answer depends on whether you want a lump sum, a line of credit, or a single simplified payment.

What to Ask a DSCR Lender Before You Refinance

• What is the maximum cash-out loan-to-value for a short-term vacation rental in the Keys, and is it the same as your purchase LTV?
• How much seasoning do you require on a financed purchase before cash-out, and does delayed financing apply to my all-cash purchase?
• Which income source will you use for my property, what discount do you apply, and what coverage ratio do I need?
• Does my current loan carry a prepayment penalty, and how does that change the math?
• What reserves will you require after closing, and do they increase with multiple financed properties?
