As of October 2026, Key Biscayne Vi Condo in FL has 1 home for sale. Over the 12 months ending 2026-09-20, 3 recorded sales closed at a median of $520,000, $469 per square foot, a median 61 days on market, sellers accepting 85% of original asking. At the median price and Miami-Dade County's FY2025-26 rate of 17.59 mills, annual property tax runs about $9,150 ($8,430 with the full homestead exemption).
Last 30 days in Key Biscayne: 1 new listing (median asking $480,000). As of October 20, 2026, Listing information provided by the Southeast Florida MLS (SEFMLS) / MIAMI Association of REALTORS(R). Information is deemed reliable but not guaranteed by the MLS to be accurate.
The numbers here come from a thin trading window — just three closings feeding this snapshot — so treat the median price of $520,000 and the $468.89 per-square-foot figure as directional rather than a tight range. With so few transactions, one unusual unit (a full renovation, a top-floor line, a distressed sale) can swing the median meaningfully in either direction.
A median days-on-market of 61 tells you pricing discipline matters more than urgency here. This is not a market where a listing gets multiple offers in a week; sellers who price to the comparable set close faster, and buyers who wait out a stale listing often get room to negotiate.
Figures in this note are as of July 22, 2026. The live market numbers elsewhere on this page update nightly and are newer.

MIAMI REALTORS sales records identify 20 homes in KEY BISCAYNE VI Condo that have changed hands since 2015, built between 1968 and 1968 (median 1968), with a median living area of about 1,109 sq ft and a typical 2-bedroom, 2-bath layout; 100% are condominiums. Source: MIAMI REALTORS closed-sale history compiled by Momentum Research; counts reflect homes with a recorded MLS sale, not every home in the community.
KEY BISCAYNE VI CONDO in Miami-Dade County is trading on a small number of closings, which keeps the market read closer to a working estimate than a settled trend, and the roughly two-month median time on market suggests buyers are not rushing.
Who Key Biscayne Condo is best for.
Best for
- A buyer with flexibility on timeline who can negotiate on a listing that has sat for a while.
- A buyer who wants to do unit-level diligence rather than trust an aggregate median in a thin market.
- A seller prepared to price competitively against recent closings rather than assume the last high sale sets the bar.
Probably not for
- A buyer who wants a resolved amenity package confirmed before touring — this data does not identify any.
- A buyer relying on median price-per-square-foot as a precise appraisal input given the small closing count.
- A seller expecting a fast close in a market where the median time on market runs about two months.
Price History: What Homes Here Have Actually Sold For
Median sale price over the trailing 12 months ending September 20 of each year, from record-level MIAMI MLS closed sales. Same methodology as every appreciation figure on this page: the 2026 point ($520K) IS the median in the snapshot above.
Windows contain 0 to 12 sales each (3 in the current window); every figure carries its sample size, and thin markets swing on single closings. Based on information from the Southeast Florida Multiple Listing Service (SEFMLS) or from MIAMI Association of REALTORS(R) for the period 2015 through 2026. Deemed reliable but not guaranteed.

The Key Biscayne Condo buying strategy.
If we were buying in Key Biscayne Condo 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 Key Biscayne Condo.
Reading a thin market
With only three closings in this window, per-square-foot pricing at $468.89 should be used as a reference point, not a ceiling or floor. Two comparably sized units in the same building can land on very different price-per-square-foot outcomes depending on interior condition, floor level, and view line — none of which show up in the aggregate number.
No community amenities are identified from current MLS listings, which usually means either the listing data has not been detailed or the building's amenity package is modest. Either way, a buyer should confirm directly with the association what is actually included — parking, storage, pool access, building services — rather than assume based on price point alone.
The location and the amenities are priced into every listing in Key Biscayne Condo. The deal is won or lost on condition, the comps, and the renovation math.
Why work with Momentum here
In a low-volume condo market like this one, the median stats only tell part of the story — we pull the actual recent closings unit by unit, check condition and line, and price against what is truly comparable instead of leaning on a thin aggregate.
