Market Heat
CRAINS sits in Marathon, Monroe County — the Florida Keys — and that geography is the primary price driver. With a median near $975,000, buyers are paying for waterfront proximity, Keys land scarcity, and the lifestyle that comes with this stretch of US-1. There is no manufactured amenity package here; the draw is the location itself.
The current market posture reads cautious. A median of 149 days on market, a market heat score of 28, and only eight closings in the measurement window all point to a slow, selective environment where properties sit until the right buyer arrives. The year-over-year price gain of roughly 10.8% tells you sellers have held value — but that figure coexists with extended time on market, meaning price appreciation has not translated into quick sales. Buyers have room to negotiate; sellers who need to move quickly should recalibrate expectations.

The 60-Second Overview
CRAINS market snapshot (as of July 27, 2026): the median sale price is about $975K, and a median 149 days on market for closed sales. The trailing-12-month median is up 11% from the prior 12 months, computed from record-level floridakeys closed sales (8 closings in the current window).
CRAINS is a small Keys community in Marathon where transaction volume is thin and properties command near-seven-figure medians — conditions that reflect the finite nature of Monroe County inventory rather than a broad, liquid market.
Who CRAINS is best for.
Best for
- Buyers with patient capital and a long hold horizon who understand that Keys land scarcity underpins value even when days on market run long.
- Second-home buyers whose primary goal is use and enjoyment, not near-term liquidity — the slow market is less a concern when you are not watching for an exit.
- Buyers who have already done comparative underwriting on Monroe County inventory and can act confidently when a property is priced fairly.
Probably not for
- Buyers who need a high transaction volume to feel confident in their valuation — eight closings in the window does not provide that assurance.
- Anyone on a compressed timeline who cannot absorb a negotiation process that may stretch across weeks in a slow-moving market.
- Budget-driven buyers seeking entry-level Keys exposure — at a median near $975,000, CRAINS does not offer a discounted path into the market.
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 ($975K) IS the median in the snapshot above, and the move from 2025 ($880K) IS the +10.8% one-year change.
Windows contain 3 to 17 sales each (8 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 CRAINS buying strategy.
If we were buying in CRAINS 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 CRAINS.
A thin market with real pricing power
Eight closings in the measurement window is not a rounding error — it is the market. When so few transactions set the median, a single outlier sale can move the number materially in either direction. The reported 10.8% year-over-year gain should be read with that context in mind: it reflects real pricing pressure in a constrained inventory environment, but it is not statistically deep enough to forecast with confidence. Buyers should anchor to comparable sales analysis, not headline percentage moves.
The 149-day median days on market is the number that should govern negotiation strategy. Properties here are not being absorbed quickly, which gives a prepared, pre-approved buyer genuine leverage on both price and terms. Sellers, in turn, need to price at or close to market on day one — overpricing in a thin, slow market compounds carrying costs and can stigmatize a listing in a community where every buyer already knows what is available.
The location and the amenities are priced into every listing in CRAINS. The deal is won or lost on condition, the comps, and the renovation math.
Why work with Momentum here
In a market this thin, the brokerage you work with needs to track every comparable sale with precision and know how to read a slow-market negotiation — not just quote a year-over-year percentage. Momentum brings that discipline to CRAINS: honest pricing analysis grounded in the actual transaction record, and straight advice on when an asking price reflects the market and when it does not.
