Coastal Florida Mortgage Questions, Answered

Straight answers to what buyers and investors ask most about financing in the Keys and coastal Florida.

Can I get a mortgage for a short-term rental in the Florida Keys?

Yes. Short-term rentals in the Florida Keys are typically financed with a DSCR loan, which qualifies the property on its projected rental income rather than your personal income. Most lenders require 20 to 25 percent down and a 620 to 660 minimum credit score. Because the Keys have one of the strongest nightly-rate markets in Florida, many Airbnb and VRBO properties cash flow well enough to qualify on the rental income alone.

What is a DSCR loan and do I have to show my income?

A DSCR (Debt Service Coverage Ratio) loan is an investor loan that qualifies you on the property's cash flow instead of W-2s, tax returns, or pay stubs. The lender compares the property's monthly rent to its monthly payment. A ratio of 1.0 means the rent covers the payment exactly, and most programs want 1.0 or higher, though some allow lower ratios with a larger down payment. There is no personal income documentation, which makes it the most common loan for self-employed investors and full-time landlords.

How much do I need to put down on a jumbo loan in coastal Florida?

A jumbo loan is any mortgage above the conforming loan limit, which is roughly 832,750 dollars for most of Florida. On coastal and Keys properties, down payments typically run 10 to 20 percent depending on the loan amount, your credit, and whether it is a primary home, second home, or investment. Strong borrowers can often secure jumbo financing with 10 percent down and no mortgage insurance.

Do I need flood insurance to buy a home in the Florida Keys?

If the property sits in a FEMA Special Flood Hazard Area, which covers most of the Florida Keys and much of coastal Florida, flood insurance is required when you finance the purchase with a mortgage. Premiums vary widely by elevation and flood zone, so the smartest move is to get a flood quote before you make an offer. We help clients price flood and insurance early so the full monthly payment is never a surprise at closing.

How does hurricane and wind insurance affect my mortgage approval?

In coastal Florida, lenders require windstorm coverage, and in high-risk areas this is often a separate wind policy or a Citizens policy. Because insurance is part of your monthly housing payment, a high premium raises your debt-to-income ratio and can change how much home you qualify for. We factor realistic Keys and coastal insurance costs into your pre-approval up front so your budget holds together through closing.

How long does it take to close on a home in Florida?

A standard financed purchase in Florida closes in 30 to 45 days. DSCR and other investor loans often move faster because there is no personal income to verify, and we have closed deals in two to three weeks when the appraisal and insurance line up quickly. Getting fully pre-approved before you shop is the single biggest factor in closing on time.

Can I buy a second home or investment property in the Keys with less than 20 percent down?

Often yes. Second homes can be financed with as little as 10 percent down on conventional financing, and many investment properties qualify between 15 and 25 percent down depending on the loan type. DSCR investor loans usually sit at 20 to 25 percent down. The right structure depends on how you will use the property, so it is worth a quick conversation before you assume you need a full 20 percent.

What credit score do I need to qualify for a coastal Florida mortgage?

It depends on the loan. Conventional loans generally start at a 620 credit score, VA loans are more flexible and have no set minimum from the VA itself, jumbo loans usually want 700 or higher, and DSCR investor loans typically start around 620 to 660. A higher score lowers your rate, but score is only one piece, and we regularly find a path for borrowers who assume they will not qualify.

What Clients Say About Working With Eli

4.7 on Google Β· 25 reviews
Closing on a waterfront property in Miami Beach required someone who understood luxury markets. Eli not only secured a jumbo loan with unbeatable terms but also connected us with an insurance specialist. His attention to detail is what makes him a standout in South Florida.
Ryan Fenn
Eli turned a nightmare scenario into a win. Our Aventura condo appraisal came in low, and the seller was rigid. He quickly pulled comps, renegotiated with the lender, and kept the deal alive. Most would have walked away. Eli fought for us. That's dedication.
Hayes Kent
Competing in Wynwood's investor-heavy market meant moving fast. Eli pre-underwrote our offer, making it bulletproof. We beat six all-cash bids, something we didn't think possible. His preparation game is unmatched.
