Florida Keys Home Prices: 24.6% Rise vs. 3.4% Appreciation
By Steve Conley
Florida Keys real estate market update: October 2026
Florida Keys home prices appear to have surged over the past year. According to Momentum Realty's September 2026 Market Pulse, the median single-family sale price reached $1.29 million, up 24.6% compared with September 2025.
But there's another number that tells a different story: the same-home appreciation rate was approximately 3.4% annually among qualifying properties that sold twice.
How can the median sale price rise so sharply when the same-home appreciation figure is much lower?
The answer lies largely in the mix of properties being sold. When a greater share of transactions involves expensive waterfront homes and luxury properties, the median can rise even without comparable appreciation across individual homes.
For buyers and sellers in the Florida Keys, understanding this distinction is essential when evaluating property values, negotiating offers and deciding how to price a home.

These figures describe different aspects of the market. The median reflects the homes that sold during the month, while repeat-sale appreciation compares qualifying properties that sold twice.
The supply, contract and price-reduction figures help explain why a higher median price does not necessarily mean sellers have unrestricted negotiating power.
1. Why Did the Median Sale Price Increase So Much?
The median is the middle sale price when transactions are arranged from lowest to highest. It does not measure how much the typical individual home appreciated over the year.
Imagine that a market has a month with many moderately priced homes selling. The median might be relatively low. If the next year's transactions include a greater share of high-value waterfront estates and luxury homes, the median could increase substantially.
That change can happen even if individual properties have appreciated much more modestly.
Momentum Realty's report identifies this change in the composition of sales as a major reason for the gap between the median-price increase and same-home appreciation.
The report also shows that homes priced at $600,000 and above represented 95% of September's sales, compared with 89% a year earlier.
This is an important distinction for the Florida Keys, where property values vary considerably by waterfront access, location, condition, lot characteristics and other features.
A median-price increase of 24.6% should not be interpreted as proof that every home, or even the typical individual home, became 24.6% more valuable.
2. What Does the 3.4% Same-Home Appreciation Rate Mean?
Repeat-sale analysis compares the sale prices of the same property at two different points in time.
Momentum Realty's September report examined 95 qualifying repeat-sale pairs, comparing homes that sold again within the latest 12-month period with an earlier sale one to three years before.
The analysis found median annualized appreciation of approximately 3.4% for those properties.
This approach helps reduce the effect of changes in the mix of properties being sold. Because the analysis follows the same homes, it offers a different perspective from comparing the median sale price across two months.
However, repeat-sale analysis has limitations. It only includes properties that meet the study's criteria and sold twice within the specified period. It does not represent every property in the Florida Keys, and individual homes can perform differently.
The 3.4% figure is therefore a useful additional market indicator, not a guaranteed appreciation rate for any particular property.
Why does the distinction matter?
For buyers, it can prevent overestimating a property's value based on the overall median.
For sellers, it reinforces the importance of reviewing comparable sales and property-specific features rather than assuming the market has raised every home's value by the headline percentage.
3. Are Buyers Gaining Negotiating Power?
Despite the higher median sale price, several indicators in the September report suggest buyers have more leverage than the headline number alone might imply.
44% of active listings have reduced their prices
Momentum Realty reported that 44% of active listings had reduced their asking prices as of October 20, 2026.
This is a point-in-time snapshot, not the percentage of all homes sold that received reductions.
A price reduction may indicate that a seller is adjusting expectations, but it does not automatically make a property a bargain. Buyers should compare the revised asking price with recent comparable sales and competing listings.
Housing supply reached 7.2 months
The report recorded 7.2 months of single-family housing supply.
Higher supply can give buyers more choice and reduce the pressure to make immediate decisions. The effect varies, however, by neighborhood, price range and property type.
New contracts declined 26.1%
The report recorded 68 new contracts in September, down 26.1% year over year.
New-contract activity can provide an indication of demand before transactions appear in closed-sale statistics. A decline suggests buyers are committing to fewer purchases than during the same month a year earlier.
Homes spent a median of 84 days on the market
The median time on market was 84 days, slightly shorter than the same month a year earlier.
This shows why market indicators should be considered together. Properties may still be finding buyers, but higher supply and more price reductions can give buyers additional opportunities to compare and negotiate.
The report's overall Market Score was 10 out of 100, which Momentum Realty classifies as a strong buyer advantage.
That score is the provider's own indicator, not a universal industry standard or a prediction of what will happen to prices.
4. What Should Buyers Do in This Market?
If you're considering buying a home in Key Largo, Islamorada, Marathon, Key West or elsewhere in the Florida Keys, use the current conditions to investigate properties carefully.
Compare similar properties
Focus on recent closed sales that closely match the property you're considering.
Compare location, size, condition, waterfront access, elevation and other features that can materially affect value. A luxury waterfront home should not be evaluated using the same assumptions as a smaller inland property.
Review the complete listing history
Look at how long the home has been listed, whether its price has changed and how it compares with competing properties.
A property that has been on the market for several months may present a different negotiating opportunity from a newly listed home priced competitively.
Evaluate the full cost of ownership
The purchase price is only one part of the financial decision.
Review insurance quotes, property taxes, maintenance, potential storm repairs and any association fees. For waterfront homes, investigate the condition of seawalls, docks and boat lifts, along with permits and access requirements.
Negotiate based on evidence
A higher median sale price does not mean you should automatically offer more. Likewise, a buyer-leaning market does not guarantee that a seller will accept a large discount.
Use comparable sales, property condition, market time and the seller's asking-price history to support your offer.
5. What Should Sellers Do?
The report also offers important lessons for homeowners considering selling.
Avoid relying solely on the median
The headline increase may not reflect the appreciation of properties in your particular neighborhood or price range.
A realistic comparative market analysis should consider recent sales of similar homes, current competition and the property's unique features.
Price strategically from the beginning
The report's price-reduction data suggests that many active sellers have adjusted their expectations.
An asking price that is too high can limit initial interest and lead to repeated reductions. A well-supported price can help attract serious buyers without unnecessarily sacrificing value.
Prepare for buyer questions
Buyers may scrutinize insurance costs, roof condition, flood exposure, permits and maintenance more closely when they have several properties to compare.
Organizing relevant documentation and addressing known issues where practical can make a property easier to evaluate.
Understand your likely net proceeds
The final sale price is not the same as the amount you receive.
Consider mortgage payoff, closing expenses, any negotiated concessions and other transaction costs when deciding whether to sell.
6. Does This Trend Apply to Every Florida Keys Community?
No. The Florida Keys contain multiple local markets, and conditions can differ by community, neighborhood and property type.
Key Largo
Buyers may compare canal homes, inland properties, condominiums and luxury waterfront estates. Flood exposure, boating access and proximity to mainland services can influence both demand and ownership costs.
Islamorada
Waterfront estates, fishing-oriented properties and homes with particular dockage or water-depth characteristics may attract different buyers from other residential properties.
Marathon
Marathon offers a range of residential options, so pricing and demand should be assessed within the relevant neighborhood and property category.
Key West
Historic homes, condominiums and waterfront properties can have different pricing dynamics. Historic restrictions, property condition, parking and location may affect their appeal.
A countywide or regionwide median is a starting point, not a substitute for local analysis.

7. What Should You Watch in the Next Market Report?
To understand whether the market is strengthening, cooling or stabilizing, watch several indicators together:
- Median sale price: Useful for understanding the mix and price level of properties selling.
- Repeat-sale appreciation: Helps show how qualifying individual properties have changed in value.
- New contracts: Provides a signal of current buyer activity.
- Months of supply: Indicates how much inventory is available relative to the pace of sales.
- Price reductions: Helps show whether sellers are adjusting asking prices.
- Days on market: Provides context about how quickly properties are going under contract.
The most useful analysis compares consistent reporting periods and property categories. One month's figures should not be treated as a reliable forecast on their own.
