Over the recorded series, BISCAYNE KEY ESTATES’s median sold price moved from $2,100,000 (2018) to $3,487,500 (12 months ending 2026-07-20) — +66% over that span, with every year’s figure from recorded closings, not a model.
The recorded series starts in 2018 at $2,100,000. The 2020–22 run-up did what it did everywhere — BISCAYNE KEY ESTATES’s median moved +20% from 2019 to 2022. Against the 2024 peak of $3,600,000, the current median stands at -3%. Annual sales volume here has ranged from 0 to 30 closings a year (10-yr average 11.8). With roughly 11.8 closings a year, BISCAYNE KEY ESTATES’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.
What actually trades here: 99% single-family residence, 1% townhouse, with a median of 2,889 sq ft and a median price per square foot of $1,280 in the current window.
Of the 32 recorded BISCAYNE KEY ESTATES closings since 2024, half landed between $2,960,000 and $4,356,250 (the middle two quartiles); the lowest recorded sale was $2,475,000 and the highest $6,850,000. If your home sits outside the middle band, the reason usually shows up in the size table below before it shows up in condition.
| Sold price band | Share of closings | Sales |
|---|---|---|
| Under $2,700,000 | 2 (6%) | |
| $2,700,000 – $3,666,667 | 17 (53%) | |
| $3,666,667 – $4,633,333 | 6 (19%) | |
| $4,633,333 – $5,600,000 | 3 (9%) | |
| None and up | 4 (12%) |
The same recorded closings, split into thirds by living area. Find the row your home falls in: the $/sqft figure times your square footage is the recorded-sales bracket for homes like yours here — a starting range from real closings, not a valuation of your specific property. Smaller homes here have been selling at a higher price per square foot than larger ones ($1,362 vs $1,154) — the usual pattern, since lot, kitchen and baths do not scale with floor area.
| Size group | Median $/sqft | Median sold | Sold range | Sales |
|---|---|---|---|---|
| Smaller homes 1,265–2,429 sq ft | $1,362 | $2,915,000 | $2,475,000 – $3,475,000 | 10 |
| Mid-size homes 2,488–3,525 sq ft | $1,194 | $3,475,000 | $2,750,000 – $6,350,000 | 10 |
| Larger homes 3,534–5,528 sq ft | $1,154 | $4,562,500 | $3,310,000 – $6,850,000 | 12 |
From the live MLS feed as of 2026-09-03: 7 active listings (plus 2 pending) asking from $3,800,000 to $9,200,000, median $5,478,000; 4 of 7 have been on the market over 60 days (median 64 days so far); the homes listed or recently sold were built between 1951 and 2024 (median 2000). For a seller this is the competition a buyer will tour alongside your home; for a buyer, the stale share is where negotiating room usually is. See the current BISCAYNE KEY ESTATES listings →
At BISCAYNE KEY ESTATES’s $3,487,500 median and Miami-Dade County’s adopted 17.59 mills (FY2025-26), a home assessed at that price carries roughly $61,360 a year in property tax before exemptions, or about $60,640 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 Miami-Dade County tax page.
Momentum’s market-heat index for BISCAYNE KEY ESTATES reads 38/100 (computed from DOM, sale-to-list, and absorption; 2020–21 peaked in the 70s here).
