Florida Keys Real Estate Market: What’s Happening in Each Key in Fall 2026?

If you're watching the Florida Keys real estate market, one thing is becoming increasingly clear: there isn't one single Florida Keys market.

Conditions can look very different depending on where you are.

A luxury property in Islamorada may be competing in a very different market from a home in Key West. A buyer looking in Marathon may have more negotiating leverage than someone shopping for a highly desirable waterfront property in the Upper Keys.

That is why looking only at a Keys-wide median can sometimes give buyers and sellers an incomplete picture.

As of September 2026, Realtor.com reports a $1.175 million median listing price across Monroe County, with a $975,000 median sold price, 1,843 active listings and a median of 110 days on market. The median listing price is down 4.17% year over year, and homes sold for approximately 4.55% below asking price on average. Realtor.com currently classifies Monroe County as a buyer's market.

But look more closely at individual communities, and the story becomes much more nuanced.

The Big Picture: A More Negotiable Keys Market

Countywide, buyers have more choices and more negotiating room than they had during the most competitive periods of the market.

The September 2026 Realtor.com data shows:

• Median listing price: $1,175,000
• Median sold price: $975,000
• Active listings: 1,843
• Median days on market: 110 days
• Median listing price change: -4.17% year over year
• Median sold price change: 0% year over year
• Average sale-to-list ratio: approximately 95%
• Market classification: Buyer's market

That doesn't mean every seller is cutting prices or that every property is a bargain.

It means buyers should be looking at the specific community, property type and price segment rather than assuming the entire Keys is moving in the same direction.

A separate September 2026 market analysis from Conley Group Florida also cautions that Florida Keys statistics can vary significantly depending on the reporting period, source and relatively small number of sales in some communities.

Islamorada: A Very Different Luxury Market

If you're looking at luxury real estate, Islamorada deserves its own conversation.

Realtor.com's September 2026 data shows:

• Median listing price: $2,712,500
• Year-over-year change: +33.53%
• Median sold price: $1,275,000
• Year-over-year sold-price change: +16.01%
• Active listings: 194
• Median days on market: 122 days

The median listing price in Islamorada is therefore more than twice the countywide median.

That reflects the type of inventory found in this market, including luxury waterfront properties, larger homes and highly desirable boating locations.

But there is an important detail hidden inside the numbers.

Higher prices don't necessarily mean every property is selling quickly.

Islamorada homes were taking a median of 122 days to sell, and Realtor.com reports that properties sold for approximately 4.17% below asking price on average in September. The site still classifies the community as a buyer's market.

For luxury buyers, that can create opportunities to negotiate, but the opportunity depends heavily on the individual property.

A deep-water waterfront home with excellent dockage, strong construction and a desirable location may behave very differently from an overpriced property that has been sitting on the market.

Key West: Prices Have Softened

Key West tells a different story.

Realtor.com's September 2026 data shows:

• Median listing price: $1,150,000
• Year-over-year change: -8.52%
• Median sold price: $1,050,000
• Year-over-year change: -8.70%
• Active listings: 372
• Median days on market: 118 days

That makes Key West an interesting market to watch this fall.

The median listing price has declined by more than 8% year over year, while homes are taking nearly four months to move through the market.

Realtor.com also reports that Key West properties sold for approximately 4.86% below asking price on average in September and classifies the market as a buyer's market.

For buyers, that combination can create more room for negotiation.

For sellers, it makes accurate pricing and presentation particularly important.

Key Largo: Strong Upper Keys Demand

Key Largo remains one of the most important Upper Keys markets, particularly for buyers who want easier access to mainland South Florida.

Realtor.com's September data puts the median listing price around $1.195 million.

Earlier 2026 market analysis also showed Key Largo experiencing strong year-over-year price growth and demand compared with other parts of the Keys. Conley Group Florida's September market review noted that Upper Keys communities such as Key Largo and Islamorada had been among the strongest appreciation markets during the year.

For buyers, the appeal is straightforward:

Miami access + boating + diving + waterfront communities + Keys lifestyle.

But buyers should expect to pay a premium for desirable waterfront properties.

Marathon: More Selection and More Negotiating Room

Marathon is particularly interesting because it has developed a different market dynamic from the Upper Keys.

A summer 2026 market analysis found approximately 14.3 months of inventory in Marathon, compared with about 3.5 months in the Upper Keys. The analysis characterized Marathon as a buyer's market and identified the $650,000–$900,000 segment as particularly well supplied.

That matters because Marathon is one of the Keys' most practical full-time communities.

Buyers have access to:

• Restaurants
• Grocery stores
• Medical services
• Schools
• Marinas
• Beaches
• Boating
• Fishing
• Local services

The combination of a full-time community and greater inventory can make Marathon an attractive place to shop if you're looking for value and negotiating leverage.

However, current countywide data still shows Marathon with a median listing price around $1.2 million.

So "more affordable" does not mean inexpensive.

Big Pine Key and the Lower Keys: More Space and a Different Pace

Big Pine Key and the Lower Keys offer a very different lifestyle.

These communities tend to appeal to buyers looking for:

• Privacy
• Nature
• Larger lots
• Boating
• Fishing
• A quieter residential environment
• Less tourist-oriented living

Conley Group Florida's September 2026 market analysis identifies Big Pine Key as one of the more accessible entry points in the Keys, while noting that inventory has increased substantially in some Lower Keys segments.

The Lower Keys also posted some of the strongest year-over-year average sale-price growth in Q1 2026 according to the market sources reviewed in that analysis.

That doesn't mean every Lower Keys property is appreciating rapidly.

The market is highly property-specific.

A waterfront home with excellent boating access can command a very different price from a non-waterfront home several streets away.

Why Waterfront Homes Are a Market of Their Own

For many buyers, the Florida Keys lifestyle is synonymous with being on the water.

But waterfront properties shouldn't be evaluated simply by comparing their square footage and asking prices.

Buyers should look closely at:

Water depth

Can the waterway accommodate the type of boat you own?

Open-water access

How long does it take to reach the Atlantic or Gulf?

Bridge clearance

Will your boat fit under the bridges along the route?

Dock

Is there a permitted and usable dock?

Seawall

What is its age and condition?

Flood exposure

What is the property's elevation and flood profile?

Insurance

What will homeowners, wind and flood coverage actually cost?

These factors can materially affect both value and resale demand.

Conley Group Florida's September market analysis specifically notes that waterfront properties with private docks, deep-water canals or direct ocean frontage remain among the most sought-after segments of the Keys market.

Why the Countywide Median Can Be Misleading

This is especially important in the Florida Keys.

Imagine that one month has several $2 million waterfront sales and another month has more modest condos and non-waterfront homes.

The median can move significantly even if the underlying market hasn't suddenly changed.

This is particularly relevant in smaller communities where relatively few properties close each month.

For that reason, buyers and sellers should look beyond:

"What is the median price?"

and ask:

"What have comparable properties actually sold for?"

The most useful comparison is usually:

Same community + similar property type + similar size + similar waterfront characteristics + recent closing date.

What This Means for Buyers in Fall 2026

For buyers, the current market presents a mixture of opportunity and selectivity.

If you're looking in Islamorada:

Expect a premium market, but don't assume sellers will automatically receive their asking price. The median listing price is high, but properties are spending more than four months on the market at the median.

If you're looking in Key West:

The year-over-year decline in listing and sold prices creates an interesting environment for buyers who are prepared to negotiate.

If you're looking in Marathon:

The higher inventory levels reported earlier this year can give buyers more choice and potentially more leverage.

If you're looking in Big Pine or the Lower Keys:

You may find more space and a quieter lifestyle, but you still need to evaluate each property individually because smaller markets can experience significant swings in monthly statistics.

What This Means for Sellers

The current market doesn't mean sellers need to panic.

But it does mean pricing strategy matters.

A seller should not simply look at the highest active listing in the neighborhood and use that as their price target.

Instead, look at:

• Recent closed sales
• Current competing listings
• Price reductions
• Days on market
• Property condition
• Waterfront characteristics
• Insurance costs
• Renovations
• Permits
• Dock and seawall condition

A property that is correctly priced from the beginning can stand out in a market where buyers have more choices.

Fall 2026: The Bottom Line

So, what is happening in the Florida Keys real estate market this fall?

The answer depends on where you're looking.

Monroe County overall is showing a softer, more negotiable market. Median listing prices are down 4.17% year over year, homes are taking 110 days to sell at the median, and buyers are paying about 95% of asking price on average.

But the luxury market in Islamorada is telling a different story, with a $2.71 million median listing price and a 33.53% year-over-year increase in that measure.

Meanwhile, Key West has seen median listing prices fall 8.52% year over year, creating a more negotiable environment for buyers.

And Marathon and the Lower Keys continue to offer their own combination of inventory, lifestyle and pricing dynamics.

The biggest takeaway?

Don't ask, "How is the Florida Keys real estate market?" Ask, "How is the market for the type of property and community I'm interested in?"

A luxury waterfront home in Islamorada, a historic property in Key West and a family home in Marathon can all be experiencing very different market conditions at the same time.

For buyers, that means there may be opportunities, but you need to know where to look.

For sellers, it means accurate pricing and understanding your specific competitive market are more important than relying on a countywide headline number.

If you're considering buying or selling in the Florida Keys this fall, recent comparable sales and current competing inventory can tell you much more about your property's position than a single median price.
