In the Florida Keys, market-wide price data is painting a picture that matches few actual transactions. A small number of record sales at the top of the range have skewed averages and medians upward, while a larger band of older canal homes continues to correct downward. Together, these segments produce a composite number that fits neither, complicating decisions for buyers and sellers alike.
Sandy Tuttle, founder of Island Welcome Real Estate, operates primarily in unincorporated Monroe County in the Lower Florida Keys. She sees the divergence from both sides, noting that interpreting the market without local context is one of the hardest challenges for out-of-state buyers.
Historically, Keys housing stock was uniform, with most homes around 1,000 square feet and featuring two bedrooms and two baths. That changed over the past decade as new construction introduced homes ranging from 4,000 to 10,000 square feet, built to current code with wind ratings exceeding 180 mph. This has created an entirely new product category in a market that previously had none.
As this high-end inventory trades, it generates prices with no precedent in the region. Tuttle points to single-family sales in the Lower Keys at $12 million and $13 million within the past five years, and Islamorada has seen sales in the $20 million to $22 million range recently. “We are constantly crushing ceilings that the Florida Keys have always had,” she said.
These outlier sales represent a genuine, growing segment but are statistically disruptive in a market where the average sale price is closer to $1.5 million. A handful of eight-figure closings materially shifts both the mean and median for the entire chain, which is then reported as market appreciation.
Below that level, conditions differ dramatically. Canal homes priced under $1 million are mostly 1980s and 1990s construction, smaller and built to earlier code. Inventory in this band is high, buyer demand is soft, and competition among sellers has led to real price corrections, not appreciation. “You cannot talk to that seller and tell them the market moved five to seven percent last year,” Tuttle said. Days on market in this segment run longer than the overall average, though for different reasons than at the top, where the buyer pool is simply smaller.
The practical effect is that consumer-facing valuation tools applying broad price-per-square-foot methodology across the chain produce misleading output. A seller in the sub-million-dollar canal band might price based on headline appreciation, while a buyer assumes a rapidly rising market. Tuttle’s approach is to analyze only the price range the client operates in, looking at absorption, days on market, and pricing behavior within that band. Sellers with properties outside the high-demand profile receive realistic positioning advice, and buyers are shown where pricing is fair or inflated relative to comparable inventory in their range.
As older ground-level stock converts to new construction, the spread between the two segments is likely to widen further, making chain-wide averages even less useful as a guide.
