Hidden Bay

Nearly 400 Homes on Four Dominant Floorplates

The Miami-Dade County Property Appraiser record for 3370 NE 190th Street covers 372 folios. I grouped them under “100 Hidden Bay Condo,” which accounts for 371 of the 372, and filtered that group to 370 residential homes, setting aside one non-dwelling folio the same way I set aside parking, cabana and storage everywhere on this site.

This is a large building, and its size distribution is unusually tidy for one this size: units run from 800 to 5,200 square feet, with a median of 1,660 square feet, but four sizes — 1,610, 2,130, 1,870 and 1,660 square feet — account for 305 of the 370 homes, or 82.4% of the building. That’s a high degree of standardization; most buyers and sellers here are trading one of a small handful of repeated layouts, which is exactly the kind of building where a $/sq ft comparison across sales means something.

One thing I want to flag plainly rather than paper over: the county’s bedroom field is essentially blank for this building. It reports zero bedrooms for 368 of the 370 homes (99.5%), which I take to mean the field wasn’t populated at the unit level for this declaration, not that 368 homes are literally studios — a 5,200-square-foot home with no bedrooms on file makes that clear enough on its own. Rather than publish a bed-mix breakdown built on data I don’t trust, I’m leaving it out and saying so here.

2026 assessed values for the 370 homes range from $156,690 to $3,035,340, with a median of $550,421. I have no county-sourced figure for the building’s age, floor count, architect or amenities, and I’m not filling any of that in from memory — none of it is in the tax roll.

The Sales Record, Year by Year

42 qualified sales over four years, with double digits in three of the four, is enough volume for me to talk about direction with more confidence than I can on the smaller buildings in this series — though 2026’s six sales are a partial year and shouldn’t be read against the full-year totals above it. The largest single transaction I can see in this four-year window is $3,500,000, closed 12/4/2023 on a 4,080-square-foot home — well above the building’s typical floorplate, and a reminder that this median is drawn from a real spread of unit sizes, not a single repeated layout.

Median Price Rose While Price Per Square Foot Fell — Why?

From 2023 to 2025, median sale price climbed 10.7%, from $722,500 to $800,000. Over the same two years, median price per square foot fell 4.5%, from $448 to $428. Those two numbers are telling different stories, and per the rule I follow on every building in this series, when price and $/sq ft disagree, the $/sq ft figure is the one to trust for value — median price is sensitive to which floorplates happened to sell in a given year, and with 82.4% of this building concentrated in four sizes, a shift toward the larger end of that mix is enough to lift the median price without the building actually getting more expensive per foot.

2026’s six sales to date read as a partial reversion: median price at $733,750, roughly back toward 2023-2024 levels, and median $/sq ft at $448, identical to 2023’s figure. I’d treat that as a data point, not a conclusion — six sales in a partial year is a smaller sample than any of the three full years above it, and the direction could still move before the year closes.

Put the two-year window in percentage terms and the gap is stark: a buyer relying on the median price alone would tell you this building got meaningfully more expensive between 2023 and 2025. A buyer relying on $/sq ft would tell you the opposite — that value per foot actually softened slightly over the same period. Both are reading the same 36 sales (2023 through 2025) correctly; they’re just measuring different things. I’d rather show you both lines and let you see the disagreement than average them into a single number that hides it.

Who Hidden Bay Fits Best

This building suits a buyer who wants a well-established Aventura waterfront address with real trading volume and a standardized set of floorplates to compare against — the kind of building where you can point to a dozen-plus recent sales of a comparable unit and price with confidence. At roughly one home in 35 turning over in a given year, it’s also the most liquid of the six buildings I’ve drafted this round by a wide margin, which matters if resale flexibility is part of your decision.

It fits less well a buyer who needs a confirmed bedroom count before they’ll consider a unit — that data isn’t reliably in the county record here, and you’ll need to verify it directly, unit by unit, rather than relying on this page or the tax roll. For a seller: with 42 qualified sales across four years and a strong showing again in 2026, you have a real comp set to work from. I’d price off the $/sq ft trend rather than the median price line, given the divergence between the two documented above — and I’d expect a buyer’s agent to do the same.
