Market Heat
Coral Harbour sits on Plantation Key in Monroe County — the Florida Keys — where location alone is the primary price driver. The median closed price stands at $650,000, and with only five closings in the tracked window, individual transactions move that figure meaningfully in either direction. Buyers should treat the median as an orientation point, not a ceiling or a floor.
At a market heat score of 59 and a median days-on-market of 57 days, this is a measured, deliberate market — not a bidding-war environment. Year-over-year price movement is essentially flat at 0.2%, yet the community has gained 55% in median value since 2012, reflecting the long-term scarcity dynamics that define Monroe County real estate. The current posture gives buyers negotiating room that has not existed in prior cycles; sellers need to price with precision, not optimism.

The 60-Second Overview
CORAL HARBOUR market snapshot (as of July 27, 2026): the median sale price is about $650K, and a median 57 days on market for closed sales. The trailing-12-month median is up 0% from the prior 12 months and up 55% since 2012, computed from record-level floridakeys closed sales (5 closings in the current window).
Coral Harbour is a small Keys community where the combination of Monroe County's constrained land supply and Plantation Key's island setting underpins pricing at a level that has proven durable over the long term — even as the near-term market has largely paused to find its footing.
Who CORAL HARBOUR is best for.
Best for
- A buyer targeting a Keys second home or retreat who has budgeted at or near the $650,000 median and understands that Monroe County insurance and compliance costs are part of the total ownership equation.
- A buyer who values the scarcity argument — Monroe County's restricted development environment — and is comfortable with a 57-day or longer timeline to close.
- A seller who is willing to price precisely and not chase a number disconnected from the thin, current comparable set.
Probably not for
- A buyer expecting a broad selection of active listings or frequent new inventory — five closings in the window signals this is a very small, infrequently traded community.
- A buyer who needs on-site amenities or a managed community structure; none are identified here.
- Anyone whose budget requires stretching and who has not fully modeled Keys-specific carrying costs — flood insurance, wind insurance, and potential elevation or compliance work can be substantial.
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 ($650K) IS the median in the snapshot above, and the move from 2025 ($649K) IS the +0.2% one-year change.
Windows contain 1 to 10 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 CORAL HARBOUR buying strategy.
If we were buying in CORAL HARBOUR 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 CORAL HARBOUR.
What the numbers actually tell you
A thin transaction volume — five closings in the measured window — means statistical averages carry wide margins. A single outlier property, whether a waterfront tear-down or a fully renovated canal home, can shift the median noticeably. That reality cuts both ways: a buyer who anchors too rigidly to $650,000 as a benchmark may miscalibrate on a specific listing, and a seller who interprets a recent high comparable as the new floor is likely to sit unsold. Condition and water access are almost certainly the dominant valuation variables here, though the MLS data does not itemize those specifics.
No community amenities were identified from current MLS listings, which tells its own story. Coral Harbour is not a clubhouse-and-amenity-package community; its appeal is the Keys environment itself — boating, fishing, and the character of a small island address. Buyers drawn here are buying a place and a lifestyle geography, not a managed amenity set. If resort-style on-site amenities are a priority, this community will disappoint.
The location and the amenities are priced into every listing in CORAL HARBOUR. The deal is won or lost on condition, the comps, and the renovation math.

Why work with Momentum here
Monroe County real estate carries layers that mainland transactions rarely require — flood zone classifications, wind mitigation documentation, septic and FEMA compliance nuances, and the permit constraints that come with Keys building regulations. In a low-volume market like Coral Harbour, comparable sales data is sparse and can be stale. Momentum's job is to contextualize each listing against the full Monroe County transaction picture, not just the handful of Coral Harbour closings, so that buyers make offers grounded in reality and sellers arrive at list prices that actually clear.
