As of November 2026, the MLS records 1 closed sale in Biscayne Island Resub in Miami, FL, the most recent in November 2026. Across Miami as a whole, 1,547 homes closed in the last 12 months at a median of $550,000, 67 median days on market. At that median and Miami-Dade County's FY2025-26 rate of 17.59 mills, annual property tax runs about $9,680 ($8,960 with the full homestead exemption).
Biscayne Island Resub is not showing any closed sales in the current MLS snapshot window, which means there is no fresh transaction trail to read a trend from. That is a data condition, not a verdict on the community itself, but it changes how we approach pricing here: instead of leaning on a rolling median or days-on-market pattern, we have to work from active listings, prior closed comps outside the window, and direct property-level research.
For a buyer or seller, that posture calls for more legwork before a number gets attached to any specific home. We would pull the last known closed comps for this platted resub, cross-check against what is currently listed nearby, and treat any pricing conversation as bespoke rather than formula-driven. This is a community where the plan has to be built one address at a time.

The 60-Second Overview
Biscayne Island Resub is a platted resubdivision in Miami-Dade County, and the current MLS feed does not show a defined set of community amenities tied to active listings, which is common for small or older platted sections where amenity data was never itemized in the system.

Who Biscayne Island is best for.
Best for
- A buyer targeting a specific known address in this plat rather than shopping a general market
- A buyer or seller comfortable doing (or paying for) direct comp and plat research before pricing a transaction
- Someone prioritizing lot or plat characteristics over amenity packages
Probably not for
- A buyer who wants amenity data and a recent sales trend before making an offer
- A seller expecting a fast, comp-driven pricing conversation based on recent closings
- Anyone unwilling to invest time in property-specific research given the thin current MLS data

The Biscayne Island buying strategy.
If we were buying in Biscayne Island 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 Biscayne Island.
A resub plat with a thin data trail
The "Resub" in the name signals this is a resubdivided plat, typically a smaller, previously platted area that was reconfigured at some point. Those plats often carry distinct lot lines, setbacks, or deed restrictions that do not show up in a market summary but matter a great deal at the contract stage.
With zero closings recorded in the current window and no amenities pulled from active listings, there is not enough aggregate data here to describe a market rhythm. That is a cue to research this one at the parcel level: pull the plat, check recorded comps beyond the current window, and verify what is actually attached to any specific address before forming an opinion on value or timing.
The location and the amenities are priced into every listing in Biscayne Island. The deal is won or lost on condition, the comps, and the renovation math.
