In the Florida Keys, aggregate market data paints a picture that matches few actual transactions. A small number of record-breaking sales at the upper end have skewed averages and medians upward, while a large segment of older canal homes has been experiencing price corrections. When averaged together, these two distinct markets produce statistics that fit neither.
Sandy Tuttle, founder of Island Welcome Real Estate, works primarily in unincorporated Monroe County in the Lower Florida Keys and sees the gap from both perspectives. She describes the current statistical landscape as one of the most challenging for out-of-state buyers to interpret without local context.
The Florida Keys housing stock historically was quite uniform, with most properties averaging around 1,000 square feet and featuring two-bedroom, two-bathroom layouts. Over the past decade, that has changed dramatically. New construction now includes homes ranging from 4,000 to 10,000 square feet, built to current code with wind ratings exceeding 180 miles per hour. This has created an entirely new product category in a market that previously did not have one.
As this luxury inventory begins to trade, it has produced transaction prices with no historical precedent. Tuttle points to single-family sales in the Lower Keys at the $12 million and $13 million marks within the past five years. Islamorada has recorded sales in the $20 million to $22 million range over the past year.
“We are constantly crushing ceilings that the Florida Keys have always had,” Tuttle said. These transactions represent a genuine and growing segment, but they are also statistically disruptive in a market where the dominant average sale price sits closer to $1.5 million. A handful of eight-figure closings materially moves both the mean and the median for the entire chain, which is then reported to consumers as market appreciation.
Below that, conditions look different. Canal homes priced under $1 million are largely 1980s and 1990s construction, smaller two-bedroom layouts built to earlier code. Inventory in this band is high, buyer demand is comparatively soft, and competition among sellers has produced real price corrections rather than 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 that segment also run substantially longer than the reported average, though for different reasons than at the very top, where the buyer pool is simply smaller.
The practical consequence is that consumer-facing valuation tools, which apply broad price per square foot methodology across the chain, produce output that can mislead buyers and sellers in opposite directions simultaneously. A seller in the sub-million-dollar canal band reads a headline appreciation figure and prices accordingly. A buyer in the same band assumes they are entering a rapidly rising market.
Tuttle’s approach is to strip the analysis down to the price range the client is actually operating in, then look at absorption, days on market, and pricing behavior within that band alone. Sellers whose properties fall outside the current high demand profile are counseled on realistic positioning. Buyers are shown where pricing is aggressive, fair, or inflated relative to comparable inventory in their range rather than relative to the market as a whole.
As older ground-level stock continues converting to new construction, the spread between the two segments is likely to widen further before it narrows, making chain-wide averages less useful as a guide, not more.
