Biscayne Key Estates trades in a narrow, high-value lane — a median price of $3,487,500 and a median $1,279.84 per square foot put this community well above typical Miami-Dade comparables. At this price point, the number of buyers who can transact is small, and that scarcity, not marketing, is what sets the pace here.
The pace is slow by design. A median 180.5 days on market and a market heat score of 38 point to a deliberate, low-urgency environment where sellers who price accurately and buyers who do their diligence carefully both come out ahead. The 5.4% year-over-year gain shows the price floor holding even as deals take longer to close — this is a market rewarding patience over speed on both sides of the table.
Figures in this note are as of July 21, 2026. The live market numbers elsewhere on this page update nightly and are newer.
Biscayne Key Estates right now
🟢 Buyer-leaning market. 27.0 months of supply and 0% of the inventory already under contract give buyers above-average negotiating leverage.Why it matters: months of supply is how long today's inventory would last at today's sales pace; under-contract share is the portion of homes for sale that already have a buyer.Momentum Research analysis of MIAMI MLS records, as of November 10, 2026. Confidence: Medium (9 active and pending listings, 4 closed sales in 12 months).
What's unique here: the median sale price is about 7x the typical Miami-Dade County sale ($3.97M vs $550K, trailing 12 months, MIAMI MLS records).

Who Biscayne Key Estates is best for.
Best for
- Buyers purchasing at the upper end of the Miami-Dade market who can accommodate an extended closing timeline.
- Sellers with a well-conditioned, accurately priced property willing to market through a multi-month sales cycle.
- Buyers comparing price-per-square-foot across a small pool of high-value listings rather than a broad market.
Probably not for
- Buyers who need to close within a fast, fixed window.
- Sellers expecting rapid turnover based on typical market-wide days-on-market figures.
- Buyers relying on a large set of recent comparables — the closing count here is limited.
The Biscayne Key Estates buying strategy.
If we were buying in Biscayne Key Estates 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.
Use your leverage. With inventory sitting, there is room to negotiate on anything dated or overpriced and to ask for repairs or a rate buydown.
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 Biscayne Key Estates.
Price Held, Pace Stretched
With only about a dozen closings feeding the current snapshot, this is a thin market — every sale carries more weight in shaping the median, and comparables should be read individually rather than trended casually. The $1,279.84 per-square-foot figure reflects the premium nature of the product here, but with that few transactions, condition and specific lot or view characteristics can swing outcomes meaningfully.
A median 180.5 days on market is the standout number. That is a market where offers get negotiated, financing and inspection periods run their full course, and pricing that misses the mark sits — sometimes for months — before it corrects. The market heat score of 38 confirms it: this is not a bidding-war environment, it is a considered-purchase environment.
The location and the amenities are priced into every listing in Biscayne Key Estates. The deal is won or lost on condition, the comps, and the renovation math.
Why work with Momentum here
A market with a thin transaction count and a six-month-plus median timeline rewards precise pricing and patient negotiation over volume-based tactics. We track the individual closings that move this median, not just the headline number, so sellers price defensibly and buyers know what leverage they actually have before they write an offer.

What it really costs to own in Biscayne Key Estates
The parts of the monthly number a mortgage calculator leaves out, from the tax roll, the MLS, Citizens and FEMA. Property facts only.
| Property tax | Current owners' bills run a median of $39,401/yr across 8 listings here (MLS tax records, 2026-11-12). |
|---|---|
| Home and flood insurance | The average Citizens Property Insurance premium in Miami-Dade County is $1,891/yr (56,357 policies, Citizens detail by county, April 2026); private-market quotes depend on roof age, wind mitigation and construction. |
| Roof and age | Median build year 2000 across 9 listings. An original roof here would be about 26 years old; under Florida's 2022 reform (SB 2-D) carriers may require an inspection past 15 years, so budget for a roof report, and for replacement where it fails. |
