THOMPSON & ADAMS
Homes for Sale in Marathon, FL
True comps, carrying-cost math, and listings before the portals.

Thompson & Adams sits in Marathon, Monroe County — the Florida Keys — and the median price of $1.6 million reflects what Keys waterfront or water-access inventory commands, not a premium layered on top of a mainland baseline. At this price point, condition, lot orientation, and water access type (canal, open bay, ocean) drive wide spread around that median, and buyers should expect meaningful variation between listings rather than a tight cluster near the midpoint.
The median days on market of 127 days — across only three closings in the current window — signals a slow-moving, thin market. That is not unusual for high-price Keys submarkets, but it is consequential: sellers need patience and realistic pricing from day one, and buyers have negotiating room that does not exist in faster-moving corridors. Low transaction volume also means any single outlier sale can shift the median materially, so treat the data as directional, not definitive.
The 60-Second Overview
THOMPSON & ADAMS market snapshot (as of July 27, 2026): the median sale price is about $1.60M, and a median 127 days on market for closed sales.
Thompson & Adams is a low-inventory submarket within Marathon where the $1.6 million median reflects Keys geography premiums — lot position and water access are the dominant value levers — and where the pace of sales rewards patience on both sides of the transaction.
Who THOMPSON & ADAMS is best for.
Best for
- Buyers with a $1.6 million-plus budget who are specifically seeking Keys geography and understand that water access and lot orientation — not amenities — drive value here.
- Buyers with flexibility on timing who can absorb a longer search and closing timeline without pressure to close on an arbitrary deadline.
- Sellers who are prepared to price precisely from day one and hold through a market that typically takes well over three months to close a transaction.
Probably not for
- Buyers who need to close quickly or who are on a rigid relocation timeline — the 127-day median pace is not negotiable by motivation alone.
- Buyers expecting HOA-managed amenities or community infrastructure as part of the value proposition — none are identified here.
- Buyers seeking a data-rich comparable market where pricing confidence is easy to establish — three closings in the window is not that environment.
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 ($1.60M) IS the median in the snapshot above.
Windows contain 0 to 3 sales each (3 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 THOMPSON & ADAMS buying strategy.
If we were buying in THOMPSON & ADAMS 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 THOMPSON & ADAMS.
What the numbers actually tell you
Three closings in the measurement window is a thin data set, and buyers should weigh that before anchoring hard to the $1.6 million median. The figure is useful as a market signal — this is unambiguously upper-tier Keys pricing — but it would take only one atypical sale to move that number significantly. Underwriting a purchase decision on a single median derived from three transactions requires additional comparable research, and that is exactly the kind of work that separates a confident offer from an overexposed one.
No community amenities are identified from current MLS listings, which is consistent with the Keys pattern of value residing almost entirely in the individual lot and structure rather than in shared infrastructure. Buyers accustomed to HOA-maintained amenity packages should recalibrate: the draw here is location, water proximity, and the specific physical attributes of each property — not a clubhouse or a gated entry. That also means fewer carrying costs tied to association dues, but it places even greater weight on thorough due diligence at the property level.
The location and the amenities are priced into every listing in THOMPSON & ADAMS. The deal is won or lost on condition, the comps, and the renovation math.
Why work with Momentum here
Thin-market transactions in the Florida Keys carry outsized risk when representation is generic. With only a handful of closings to anchor pricing, both buyers and sellers need a team that can source and interpret comparable data beyond this submarket's own limited transaction history, negotiate effectively in a slow-velocity environment, and flag the due-diligence complexities — flood zone classifications, wind mitigation, septic and dock permitting — that are routine in Monroe County and unfamiliar to buyers coming from the mainland. Momentum brings that operational fluency to every Keys engagement.
