One Bay Residences

Thirty-Eight Townhomes on the Bay

The Miami-Dade County Property Appraiser record for 455 NE 39th Street covers 39 folios under “One Bay Condo.” 38 of those are residential homes; the remaining folio is a non-dwelling parcel, filtered out the same way I filter parking, cabana and storage everywhere on this site. That 38-home count matches what the building itself markets — a genuinely useful cross-check when the county record and the developer’s own numbers agree.

Sizes here vary more than at most buildings I’ve covered: 877 to 2,561 square feet, with a median of 1,645 square feet — nearly a 3x spread between the smallest and largest unit, on a building of only 38 homes. The bed mix is 8 one-bedrooms (21.1%), 16 two-bedrooms (42.1%) and 14 three-bedrooms (36.8%). Four sizes recur most often — 1,794, 877, 2,236 and 1,475 square feet — covering 26 of the 38 homes (68.4%), consistent with a building built out across roughly six distinct floorplans rather than one repeated layout. That range matters later in this page: it’s the reason median sale price and median $/sq ft tell noticeably different stories here.

2026 assessed values for the 38 homes range from $299,522 to $1,609,803, with a median of $890,340 — a wide spread, again reflecting the range of unit sizes rather than one uniform product. 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.

Ten Sales in Four Years, Mostly Single Data Points

Ten qualified sales across four years, on a 38-home building, sits right at the edge of what I’m willing to call a record at all — and three of those four years contributed only one or two sales apiece. A “median” built from a single sale isn’t really a median; it’s just that one transaction’s price, and I’d treat 2023’s and 2026’s rows accordingly. 2024, with six sales, is the only year here with enough volume that I’d lean on its $900,000 / $681-per-foot figures with any real confidence.

Look at the $/sq ft column across the full table and it moves without a clean pattern: $725, then $681, then $838, then $669. That’s not a curve I’d fit a trend line to. It’s four small samples of a building with real size variation, and the honest read is that the per-foot price this building commands depends heavily on which specific units happen to trade in a given year — not that the building is getting steadily more or less valuable.

Did One Bay Residences’ Median Price Really Double in 2025?

On the surface, yes: $900,000 in 2024 to $2,010,000 in 2025 looks like the building’s value roughly doubled in a year. It didn’t, and this is the clearest example in this batch of buildings of why I lead with $/sq ft over median price. 2025 had exactly two qualified sales: $2,150,000 for a 2,561-square-foot home and $1,870,000 for a 2,236-square-foot home — both well above the building’s 1,645-square-foot median size, and both landing close to each other at $840 and $836 per square foot. Median $/sq ft for the year comes out to $838, which is elevated relative to 2024’s $681 (up 23.1%), but nowhere near the 123.3% jump the raw median price suggests.

What actually happened, as best the record shows it, is that 2025’s two sales both happened to be large units, and large units carry large prices even at a comparable rate per foot. The median-price line makes that look like a market move; the $/sq ft line shows a more modest, and more believable, increase. I’d treat the true 2024-to-2025 shift as somewhere between 2024’s $681 and 2025’s $838 per square foot — real, on the small sample available, but nowhere near what the headline price number implies.

Who One Bay Residences Suits

This building suits a buyer who wants a Design District townhome with real floor-plan variety — six recurring layouts across a fairly wide size range — and who values the walkability and dining nearby over deep trading history in the building itself. It suits badly a buyer who wants to underwrite a purchase against a large recent comp set; at roughly one home in 15 turning over annually, and with three of the last four years producing only one or two sales, you won’t find that here.

For a seller: with only ten qualified sales across four years, and single-sale years on both ends of the current record, expect any offer to be priced primarily off 2024’s six-sale cluster rather than the more recent, thinner years. I’d also expect a buyer’s agent to ask hard questions about the 2025 jump in median price — have the $/sq ft breakdown above ready, because the raw price line alone overstates what changed. And if your unit is close in size to the building’s median (1,645 square feet), be prepared to point out that the two 2025 comps were both meaningfully larger homes, so their price tags aren’t a like-for-like comparison to yours.
