Market Heat

Key West by the Sea sits inside the Monroe County market, where land scarcity and coastal exposure have historically compressed supply and elevated pricing. The median sold price of $640,000 reflects that premium, but a year-over-year decline of 13.2 percent signals that sellers are no longer setting the pace. Buyers who were priced out or priced-cautious during the run-up now have measurable negotiating room — a shift that is confirmed by a market heat score of 36, a reading that sits clearly in buyer-leaning territory.
The longer arc still matters: prices are up 135 percent since 2012, which means owners who bought in that era are sitting on substantial equity even after the current correction. For a seller today, realistic pricing is non-negotiable — the market will not paper over an overpriced listing. For a buyer, the correction is real but the asset class remains illiquid and idiosyncratic, so every offer should rest on current comparable data, not the peak-era narrative.

The 60-Second Overview
KEY WEST BY THE SEA market snapshot (as of July 27, 2026): the median sale price is about $640K, and a median 76 days on market for closed sales. The trailing-12-month median is down 13% from the prior 12 months and up 135% since 2012, computed from record-level floridakeys closed sales (5 closings in the current window).
Key West by the Sea is a condominium community in the City of Key West, Monroe County — a market defined by constrained inventory, coastal location, and price dynamics that move independently of mainland Florida trends. With only 5 closings in the current measurement window, individual transactions carry outsized weight on reported medians, so interpreting the numbers demands context, not just calculation.
Who KEY WEST BY THE SEA is best for.
Best for
- A buyer targeting a Key West condo as a long-term hold who can anchor an offer to the current $640,000 median and use the buyer-leaning heat score as negotiating leverage.
- A cash buyer or well-qualified borrower who has already modeled Monroe County insurance costs and HOA obligations and is not surprised by what they find.
- A seller-side client with equity built since 2012 who is prepared to price at — not above — current market conditions to secure a transaction in a 76-day median DOM environment.
Probably not for
- A buyer expecting to flip quickly — a market heat score of 36 and a 76-day median days on market indicate this is not a fast-turn asset.
- Anyone whose budget is anchored to the $640,000 median but has not separately budgeted for Monroe County-specific insurance, flood coverage, and condo association costs, which can be material.
- A buyer who needs certainty from comparable data — with only 5 closings in the window, the statistical base is too thin to build tight valuation confidence without a deeper custom analysis.
Price History: What Homes Here Have Actually Sold For
Median sale price over the trailing 12 months ending July 27 of each year, from record-level floridakeys closed sales. Same methodology as every appreciation figure on this page: the 2026 point ($640K) IS the median in the snapshot above, and the move from 2025 ($738K) IS the -13.2% one-year change.
Windows contain 4 to 14 sales each (5 in the current window); every figure carries its sample size, and thin markets swing on single closings. Listing data provided by Florida Keys MLS, Inc.

The KEY WEST BY THE SEA buying strategy.
If we were buying in KEY WEST BY THE SEA today, this is the order of operations we would run for our clients.
Underwrite the condition first. Price the roof, HVAC, and systems honestly before judging any list price; condition swings value here more than square footage alone.
Match the home to real comps. Recent sales of similar condition and lot, not the asking price, tell you what a home is worth.
Move deliberately, not desperately. Neither side has a decisive edge, so a well-prepared, fairly-priced offer wins without overpaying.
Line up financing and inspection early. A pre-approval and an inspection plan let you act fast and negotiate from evidence.
Keep an agent in your corner. The listing agent works for the seller; we represent you and prepare a hand-built valuation before any offer in KEY WEST BY THE SEA.
Reading a thin, high-stakes market
A closing count of 5 transactions in the measurement window is the most important technical fact here. In a community this thinly traded, one distressed sale or one premium unit closing can swing the reported median by a meaningful margin. The 76-day median days on market reinforces the picture: properties are sitting, not flying. That is not a crisis signal in a luxury coastal condo market — it is normal for a segment where buyers travel, deliberate, and negotiate carefully — but it does mean a seller cannot expect a quick exit at an aspirational price.
The 13.2 percent year-over-year price decline deserves to be read alongside the since-2012 gain of 135 percent. The community has not given back its long-term appreciation; it has corrected from a period of compressed inventory and elevated demand. Whether the current median of $640,000 represents a floor or a midpoint in a longer softening depends on Monroe County supply dynamics and broader coastal market conditions — neither of which any automated figure can predict. What the data does confirm is that buyers have leverage they did not have recently, and sellers need to price to the current market, not to the peak.
