Buying a Home in Florida: 15-Year or 30-Year Mortgage?

2026 Rates and What They Mean for a Sarasota Purchase

Mortgage rates have come down from their 2023 peaks but remain historically significant. As of April 2026, the 30-year fixed rate averages around 6.30% and the 15-year fixed rate averages around 5.65%, according to Freddie Mac data. That roughly 65-basis-point spread between the two terms is meaningful — and it’s one reason the 15-year looks relatively attractive right now compared to periods when the spread was narrower.

Sarasota County single-family home prices have softened over the past year. The median sale price in January 2026 was $490,000, down about 7.5% year-over-year, according to the Realtor Association of Sarasota and Manatee. For a representative purchase at $550,000 — a reasonable figure for a three-bedroom home in a solid Sarasota neighborhood like Palmer Ranch, Lakewood Ranch‘s southern fringes, or the East County — a conventional 20% down payment leaves you financing $440,000.

Here is how that loan plays out under each term at current 2026 rates:

That five-year equity gap — roughly $119,500 more equity in the 15-year column — matters a lot if you plan to sell or refinance within a decade. Sarasota’s market has historically rewarded homeowners who build equity quickly, particularly before insurance and HOA costs rise.

When the 30-Year Makes More Sense in Florida

The 30-year is still the right call for a large share of Florida buyers. Here are the situations where it stands out:

• You’re stretching to afford the Florida market. After you account for homeowner’s insurance (which can run $4,000–$8,000 per year in Sarasota County for non-coastal homes, and significantly more near the water), property taxes, HOA fees, and flood insurance, the true monthly cost of Florida homeownership is higher than in most states. A lower mortgage payment preserves cash flow for those real costs.
• Your income is variable or you’re self-employed. Florida has a large population of business owners, seasonal workers, and retirees on fixed income. The 30-year’s lower required payment gives you flexibility during slower months. You can always pay extra principal when cash is flush.
• You want to preserve capital for other investments. The $907 monthly difference is roughly $10,880 per year. Invested consistently in a diversified portfolio, that amount could outpace your mortgage interest savings over 30 years — though this involves market risk the mortgage does not.
• You’re buying near or in a flood zone. In some coastal and low-lying Sarasota areas, FEMA flood insurance adds $1,500–$4,000+ per year on top of standard coverage. A lower mortgage payment leaves room for those premiums without crushing your debt-to-income ratio.
• You plan to use Florida’s homestead exemption strategically. The homestead exemption reduces your assessed value by up to $50,000 for property tax purposes, and the Save Our Homes cap limits annual assessment increases to 3% once you’re established. You qualify by making the home your primary residence, which is more feasible when the monthly payment is manageable.

When the 15-Year Makes More Sense in Florida

The 15-year shines in different circumstances — and for some buyers in the Sarasota/Manatee market, it’s clearly the superior choice:

• You have stable, high income and no high-interest debt. If your household income comfortably supports the $3,630 payment alongside Florida’s carrying costs, saving $327,000 in interest is a straightforward financial win.
• You’re approaching retirement. Many buyers in the Sarasota area are 50–65 and want their mortgage paid off before they stop working. A 15-year loan started at age 52 is done at 67. A 30-year started at the same age runs to 82. That difference has real implications for fixed-income planning.
• You’re buying for the long term and have no plans to sell. The 15-year’s $327,000 interest savings only fully materializes if you keep the loan. If you expect to stay 15+ years, the math favors the shorter term decisively.
• You want to build equity ahead of potential market softness. With Sarasota prices already down roughly 7–8% year-over-year and some uncertainty in the condo and townhome segments, building equity faster with a 15-year provides a cushion if values continue to correct.
• You qualify easily. Because 15-year rates are lower than 30-year rates, the interest cost per dollar borrowed is lower. Lenders still qualify you based on the higher monthly payment, but if your DTI is strong, you may find the rate discount makes the 15-year more appealing than it looks at first glance.

The “Pay Extra on a 30-Year” Strategy — Does It Work?

A common question: why not take the 30-year for flexibility and just pay it like a 15-year? It’s a reasonable approach, but it has a catch. The 30-year rate is currently about 65 basis points higher than the 15-year. On a $440,000 loan, that rate difference means you’re paying more interest on every dollar, even if you make larger payments.

If you take the 30-year at 6.30% and pay an extra $907 per month (matching the 15-year payment of $3,630), you would pay off the loan in roughly 15 years and 4 months — just slightly longer than the 15-year, but your total interest would be somewhat higher because of the rate difference. The strategy works, but it requires genuine discipline and forfeits the lower rate you’d get by committing to the 15-year upfront.

That said, the flexibility is real. If a major expense hits — a roof replacement, a job disruption, a medical event — you can drop back to the required $2,723 payment. With a 15-year loan, you’re locked in.

Putting It Together for Your Sarasota Purchase

There is no universally correct answer, but there is usually a clearer answer for your specific situation. Run these questions before you commit:

1. After your full Florida housing cost (mortgage + taxes + insurance + HOA + flood insurance), do you have at least 15–20% of net income left over? If not, the 30-year gives you necessary buffer.
2. Do you have 3–6 months of housing expenses in liquid savings? If not, the 30-year’s lower required payment is safer while you build that reserve.
3. How long do you realistically plan to stay? Under 7 years, the interest savings of the 15-year may not justify the tighter payment. Over 15 years, they almost certainly do.
4. Are you within 15–20 years of your target retirement date? If so, loan payoff timing matters, and the 15-year probably aligns better with your long-term cash flow needs.

Sarasota and Manatee counties attract buyers from all over the country, many of whom are making their most significant financial decision in decades. Understanding the numbers — not just the monthly payment, but the total cost and equity trajectory — is the foundation of a sound purchase. Whether you end up at 15 or 30 years, going in with clear eyes about what each term really costs over time puts you in a far better position at the closing table.

Mike Renick and Eric Teoh represented my husband and myself for both the sale of an existing property and the purchase of a new property. Their knowledge of Longboat Key and property values was exceptional.. The process of closing on both the sale and purchase was flawless. I have not hesitated to recommended them to others.

We recently purchased a condo on LBK. Eric is the reason. We were looking for several years. Eric is extremely knowledgable, professional, patient, kind, and most importantly, honest. As an example, his always gave his honest opinion of the price/value of a property instead of just supporting the list price in order to make a sale.

Frequently Asked Questions

What is the main payment difference between a 15-year and 30-year mortgage on a $440,000 Sarasota loan?

At April 2026 rates, the 30-year fixed at 6.30% runs about $2,723 per month in principal and interest, while the 15-year at 5.65% is about $3,630. That’s a $907 higher monthly payment for the 15-year in exchange for much faster equity build and lower total interest.

Why would a 30-year mortgage make more sense for many Sarasota and Manatee buyers?

Once you factor in Florida’s higher homeowner’s insurance, possible flood insurance, HOA or condo fees, and property taxes, the true monthly cost of owning here is substantial. The 30-year’s lower required payment preserves cash flow, gives flexibility for folks with variable income, and makes it easier to qualify for and maintain a primary residence with homestead exemption.

How much interest can a Sarasota buyer save by choosing a 15-year mortgage instead of a 30-year?

On the example $440,000 loan, the 30-year at 6.30% racks up about $540,453 in total interest, while the 15-year at 5.65% totals about $213,451. That’s roughly $327,000 in interest savings over the life of the loan if you stick with the 15-year schedule.

Does paying extra on a 30-year mortgage effectively turn it into a 15-year loan?

If you take the 30-year at 6.30% and consistently pay an extra $907 per month (matching the 15-year payment), you’d pay the loan off in roughly 15 years and 4 months. It works, but you’ll still pay more total interest than you would with the true 15-year at 5.65%, because every dollar is being charged the higher rate.
