In the Florida Keys, aggregate price figures are painting a picture of a market that almost nobody is actually transacting in. A small number of record sales at the top of the range have pulled averages and medians sharply upward. Meanwhile, a large and slower-moving band of older canal homes has been correcting downward. Averaged together, the two produce a number that fits neither segment, complicating decisions for buyers and sellers alike.
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 sides. She describes the current statistical picture as one of the harder things for an out-of-state buyer to interpret without local context.
For most of its history, the Florida Keys housing stock was fairly uniform. The islands catered to fishermen and weekend boaters, and the properties reflected that. Average home size sat near 1,000 square feet for decades, and two-bedroom, two-bathroom construction was the norm. Nobody was building large vacation estates.
That changed over the past ten years. New construction has introduced homes in the 4,000 to 10,000 square foot range, built to current code, with wind ratings in excess of 180 miles per hour. The result is not just larger houses but an entirely new product category in a market that previously did not have one.
As that inventory has begun to trade, it has produced transaction prices with no historical precedent in the region. 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.
Those transactions represent a genuine and growing segment. 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 back 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 that 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, which will make chain-wide averages less useful as a guide, not more.
