COCO PLUM (Marathon, FL): 5 recorded closings in the 12 months ending 2026-09-20, an 11-year price record, and the year-by-year record — every number from recorded MLS closings, none from an estimate model.
In the current window, sellers accepted a median 93.0% of original asking; the median sale took 28 days; new construction was 20.0% of recorded sales — builder pricing competes with resales here (window ending 2026-09-20).
| Year | Median sold | Median $/sqft | Median DOM | Sold ÷ original ask | Sales |

Over the recorded series, COCO PLUM’s median sold price moved from $379,000 (2012) to $1,750,000 (12 months ending 2026-09-20) — +362% over that span, with every year’s figure from recorded closings, not a model.
The recorded series starts in 2012 at $379,000. Annual sales volume here has ranged from 1 to 19 closings a year (10-yr average 3.4). With roughly 3.4 closings a year, COCO PLUM’s medians move in steps, not curves — a handful of unusual sales can swing a year, which is why the sales count sits next to every figure above.
At COCO PLUM’s $1,750,000 median and Monroe County’s adopted 8.816 mills (FY2025-26), a home assessed at that price carries roughly $15,430 a year in property tax before exemptions, or about $15,080 with the full Florida homestead exemption — a buyer’s first-year figure; a long-time owner’s Save Our Homes cap can be far lower, which is one reason resale taxes jump at closing. Municipal and special-district millage varies inside the county; see the Monroe County tax page.
Momentum’s market-heat index for COCO PLUM reads 61/100 (computed from DOM, sale-to-list, and absorption; 2020–21 peaked in the 70s here).
