Florida Keys Mortgage Market Update: August 2026

The late summer 2026 Florida Keys housing market shows continued price appreciation across most communities, with mortgage rates holding in the mid-to-upper 6% range and inventory remaining tight by national standards. Here is what buyers, sellers, and homeowners need to know about the current market, by island community.

Mortgage Rates in Late August 2026

The 30-year fixed-rate mortgage averaged 6.65% as of August 20, 2026, according to Freddie Mac, down slightly from 6.67% the prior week. The rate reached a one-year high of 6.69% in early August before easing back. Florida-specific averages sit slightly higher, in the 6.75% to 6.95% range depending on the source.

To put this in perspective, rates remain above year-ago levels (6.58% in August 2025), which continues to limit buyer purchasing power. However, the relatively narrow trading range over the past several months provides more predictability than the volatile swings of 2022 through 2024. For buyers, this means you can plan your budget with greater confidence than you could two years ago.

For specific loan programs, here is where rates are landing in the Keys market:

• Conventional loans (30-year fixed): 6.5% to 6.85% depending on credit score and down payment
• FHA loans: 6.25% to 6.5%, offering a rate advantage for qualified borrowers with lower down payments
• VA loans: Low 6% range, consistently the most favorable rates for eligible veterans
• Jumbo loans: 6.75% to 7.25% for most Keys properties, with more rate variation between lenders
• DSCR loans (investment): 6.5% to 8%, with the best pricing for borrowers above 740 credit and strong rental income coverage

Key Largo Market

Key Largo's median home sale price sits near $980,000 as of August 2026, up roughly 20% year-over-year. Median list prices hover around $1.19 million, and the median estimated value is approximately $1,060,000. These numbers reflect broad appreciation across the island, driven by continued demand from out-of-state buyers and the finite supply of single-family homes within the city limits.

Notable sub-markets within Key Largo show distinct pricing:

• Ocean Reef: The gated oceanfront community continues to be a world-class private club market with homes ranging from $2 million to well over $10 million. Inventory turnover is slower here, reflecting the long-term hold mentality of owners.
• Canal-front and bayfront: Canal-front properties start around $1 million. Bayfront and oceanfront homes range from $1.5 million to over $10 million. Deep-water access properties maintain a significant premium over shallow-water canals.
• Non-waterfront: Entry-level single-family homes start near $500,000, but availability of homes under $700,000 is limited.

Active listings in Key Largo stand at approximately 278, with days on market averaging around 103 according to Movoto. This means the market is not moving at a hyper-competitive pace, but well-priced properties in desirable locations do not sit long.

Islamorada Market

Islamorada presents a bifurcated picture. The median sale price is approximately $1.4 million, up a striking 52.6% year-over-year, while the average sale price sits around $880,000, down 21.8% year-over-year. This apparent contradiction is explained by a mix of very high-end sales raising the median while a larger volume of more moderately priced homes pulls the average down. It signals a market with wide price variation between oceanfront estates and standard residential properties.

Redfin rates the Islamorada market at just 2 out of 100 for competitiveness, suggesting extended marketing periods for most listings. This is actually good news for buyers: it means you have time to evaluate properties, arrange financing, and complete due diligence without the pressure of a bidding war. Sellers, in contrast, need to price realistically from day one.

Oceanfront listings along Windley Key and the Atlantic side start near $900,000 for smaller properties and lots, with established oceanfront estates in the multi-million-dollar range.

Marathon and Duck Key Market

Marathon's median sale price is approximately $1.0 million over the trailing three months, up 43.4% year-over-year. The median list price sits around $1.19 million. Days on market average 117, down 10% from a year ago, indicating that homes are selling somewhat faster than they were in 2025.

Open-water waterfront homes in Marathon average around $2.75 million, while canal-front properties offer more accessible price points. Duck Key, with its gated island community and Hawks Cay Resort, operates as a distinct sub-market within the Marathon area. Properties in Duck Key tend to attract second-home buyers and vacation rental investors, with pricing premiums driven by the resort amenities and secured-access environment.

For buyers looking at investment properties, Marathon and Duck Key have strong short-term rental demand thanks to the central location that puts guests within an hour of both Key West and Key Largo.

Key West Market

Key West remains the most competitive market in the Keys, with the fastest-moving inventory and the highest per-square-foot pricing. The median home value sits around $1,095,000, with a median sale price of approximately $1.3 million over the trailing three months, up 28% year-over-year. Average days to pending are approximately 48, meaning Key West homes that are priced right move quickly.

There are about 331 active listings in Key West as of mid-2026, a modest 3.4% increase year-over-year. The market is classified as "not very competitive" by Redfin with a score of 6 out of 100, but that is actually the highest competitiveness score in the Keys, meaning Key West is the closest thing to a seller's market in Monroe County.

Old Town historic properties present unique financing considerations. Many Old Town homes are non-conforming structures on small lots, and some lack off-street parking. Financing these properties requires a lender who understands historic district regulations, the City of Key West's planning and zoning rules, and the unique appraisal challenges of a market where per-square-foot pricing can be the highest in the state.

Lower Keys Market

The Lower Keys, including Big Pine Key, Summerland Key, Cudjoe Key, Stock Island, and other communities between Marathon and Key West, tend to have the lowest inventory levels and the longest marketing times in the Keys. The National Key Deer Refuge on Big Pine restricts land use and development, and the County's tier system limits density in most of the unincorporated Lower Keys.

For buyers who can be patient, the Lower Keys offer the best value propositions in the Keys. Homes here typically sell at a discount relative to the Upper Keys and Key West, and the lifestyle is quieter and more remote. Canal-front and bayfront properties in the Lower Keys are generally priced lower than comparable homes in Key Largo or Islamorada, making this area worth exploring for budget-conscious buyers who still want water access.

Inventory Trends Across the Keys

Overall, the Florida Keys market is characterized by tight supply. Statewide Florida inventory stood at 118,603 listings in Q1 2026, but the Keys represent a very small fraction of that total. The geographic constraints of Monroe County mean new supply is extremely limited, and new construction continues to be constrained by elevated building costs, strict building codes, and limited available lots.

For condos, inventory has improved slightly compared to single-family homes. The post-Surfside structural integrity requirements have created a bifurcated condo market: well-capitalized associations that have completed their milestone inspections and Structural Integrity Reserve Studies (SIRS) are attracting buyers, while associations with unresolved inspection reports or inadequate reserves are seeing units linger on the market.

For buyers, this means the condo market deserves careful due diligence. A condo with a clean SIRS report and healthy reserves is a stronger purchase than a seemingly cheaper unit in an association that has not yet addressed its structural requirements.

How the Market Affects Your Mortgage Strategy

Given the current rate environment and price levels, here is how I am advising Keys buyers in late August 2026:

Get Pre-Approved Before You Look

This has always been true in the Keys, but it is especially important now. With prices continuing to appreciate and the conforming loan limit for Monroe County at $990,150, many Keys purchases require jumbo loan financing. Jumbo loans have stricter requirements: higher credit score thresholds, larger down payments (often 20 to 30 percent), and significant cash reserves after closing. Knowing these parameters before you write an offer prevents the disappointment of falling in love with a property you cannot finance.

Factor Insurance Costs Into Your Budget

With mortgage rates in the mid-6% range and Keys prices at current levels, the single biggest budget variable for many buyers is no longer the rate, it is the insurance cost. Combined wind, flood, and hazard insurance for a Keys waterfront home typically totals $15,000 to $25,000 per year for a standard elevated canal-front property. That is $1,250 to $2,083 per month that gets added to your housing payment before you factor in taxes and HOA dues. Always get insurance quotes during your due diligence period, and ask your lender to use realistic numbers when calculating your debt-to-income ratio.

For a complete breakdown, see the guides on flood insurance and wind insurance in the Florida Keys.

Consider All Your Loan Options

With rates above 6%, it is worth comparing loan programs carefully:

• Conventional loans offer the most flexibility for primary residences with 5 percent or more down
• FHA loans are a strong option for first-time buyers and those with lower credit scores, offering rates below conventional and 3.5 percent down
• VA loans remain the best deal for eligible veterans, with zero down and the lowest rates
• Jumbo loans are the standard for waterfront properties over the conforming limit
• DSCR loans are ideal for vacation rental investors who want to qualify based on property income rather than personal income
• Non-QM loans and bank statement loans help self-employed borrowers who cannot document income with traditional W-2s and tax returns

Watch the Appraisal

With prices rising 20 to 52 percent year-over-year in different Keys communities, appraisals can lag behind contract prices. Make sure your purchase contract includes an appraisal contingency, and work with a local real estate agent who can help you price your offer realistically based on recent comparable sales. See the guide on Florida Keys appraisal issues for more detail.

Looking Ahead to Fall 2026

The consensus expectation among economists is that mortgage rates will remain in the 6 to 7% range through the end of 2026. The Federal Reserve has signaled a measured approach to rate adjustments, and the mortgage market is responding with relative stability after several years of volatility.

For Keys buyers, the takeaway is straightforward: the market is not going to suddenly become dramatically cheaper or easier. Prices are likely to continue their gradual upward trajectory due to the fundamental supply constraints of the Keys, and rates are unlikely to drop below 6% in the near term. The best strategy is to buy when you find the right property at a price that works for your budget, rather than trying to time the market.

For homeowners considering a refinance, the current rate environment is not favorable for rate-and-term refinancing unless you have a higher-rate loan from the 2023 peak. However, cash-out refinancing may still make sense if you have built significant equity and need funds for renovations, debt consolidation, or other goals.
