FONTAINE LAKE (Plantation Key, FL): 4 recorded closings in the 12 months ending 2026-09-20, a 7-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 93.5% of original asking; the median sale took 79 days; new construction was 25.0% 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 |
|---|---|---|---|---|---|
| 2026 | $1,487,500 | — | 79 | 93.5% | 4 |
| 2024 | $1,437,500 | — | 76 | 82.5% | 4 |
| 2023 | $735,000 | — | 11 | 98.1% | 3 |
| 2020 | $455,000 | — | 158 | 82.9% | 3 |
| 2018 | $570,000 | — | 47 | 97.5% | 3 |
| 2015 | $850,000 | — | 182 | 81.0% | 3 |
| 2014 | $318,500 | — | 26 | 89.9% | 3 |
Over the recorded series, FONTAINE LAKE’s median sold price moved from $318,500 (2014) to $1,487,500 (12 months ending 2026-09-20) — +367% over that span, with every year’s figure from recorded closings, not a model.
The recorded series starts in 2014 at $318,500. Annual sales volume here has ranged from 0 to 4 closings a year (10-yr average 2.3). With roughly 2.3 closings a year, FONTAINE LAKE’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 FONTAINE LAKE’s $1,487,500 median and Monroe County’s adopted 8.816 mills (FY2025-26), a home assessed at that price carries roughly $13,110 a year in property tax before exemptions, or about $12,770 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.
The table above is the closed-sale record to price a FONTAINE LAKE home against; asking prices are an opening position, recorded closings are the value.
