Key Takeaways
- The most uniform building I have measured, by assessed value — $371,943 to $707,066 — a spread of 1.9 times, the tightest in my Miami Condo Index.
- One commercial folio controls 13.3665% of the common elements — a single 25,504 sq ft unit, assessed at $4,004,128. Residential owners hold about 86.6% between them.
- The record is short and I will not over-read it — the county holds 232 qualified sales here and 169 of them are the 2021 sell-out.
- Only 37 resales exist so far — 4 lost money, at a median gain of 17.1% over a 3.0-year hold.
- 198 homes at 3900 Biscayne Boulevard, in the Design District — 121 one-bedrooms and 65 two-bedrooms — heated area 479 to 1,162 sq ft.
- I am not publishing a four-year trend — the four years rest on 8, 9, 9 and 3 sales and the size of the home sold swings between them.

The most uniform building in the index
Across the buildings measured for this site, the 2026 assessed values inside a single condominium usually run four, ten, sometimes twenty times from the cheapest home to the dearest. Quadro runs $371,943 to $707,066, with a median of $453,028.
That is a spread of 1.9 times — the tightest of any building in my Miami Condo Index. The next narrowest is Canvas at 2.1 times, then Hamptons South at 3.4.
The reason is structural. Heated area here runs only 479 to 1,162 square feet, there is no penthouse tier and no oversized combined residence, and the building spreads 198 homes across 36 distinct floorplates with no single plate covering more than 11 homes. It is a building of small variations rather than a building with a top and a bottom.
For a buyer that has a specific and practical consequence, and it is the most useful thing on this page. Where the homes barely differ, the price argument has very little room to run. In a tower spanning 500 to 5,000 square feet, a seller can always point at a different class of home to justify a number. Here they cannot: the comparable is a home very much like the one you are looking at, and both sides can see it.
The counterpart is that there is no bargain tier either. The cheapest home in the building is assessed at $371,943. There is no distressed low end to hunt for, because there is no low end.
What is actually inside the building
The county returns 200 folios at 3900 Biscayne Boulevard: 198 residential homes, one reference folio, and one commercial unit.
That commercial unit deserves more than a footnote. It is 25,504 square feet, assessed at $4,004,128, and it carries 13.3665% of the undivided interest in the common elements. One folio, more than an eighth of the building. The 198 homes share the remaining 86.6% between them, which works out at roughly four tenths of one per cent each.
This is a governance fact, not a trivia item: on any matter decided by percentage of ownership interest, that single commercial owner votes more than four hundred typical residential homes would. I am reporting the recorded share, not the association’s voting rules — those are in the declaration, which is not in the Property Appraiser’s record, and any buyer should read it.
The residential mix is 121 one-bedrooms, 65 two-bedrooms and 12 studios. The median home is 780 square feet.
The record sale is $1,044,000 for N-915 in February 2025 — 1,106 square feet at $944 per square foot.
A record too young to lean on
The county’s sales record for this building begins in 2020, and it holds 232 qualified sales in total. 169 of those — more than seven in ten — are the 2021 sell-out, at a median of $535,000 and $673 per square foot.
Everything else in the record is what has happened since, and it is not much: 37 resales in total, at a median hold of 3.0 years. Of those, 4 sold at a loss — 10.8% — at a median gain of 17.1%.
Narrowing to the people who bought new in the sell-out and have since sold: 30 have resold in a qualified, arm’s-length transaction, 3 of them — 10.0% — for less than they paid, at a median outcome of +19.9%.
Those numbers are fine. They are also thin, and on a five-year-old building they cannot tell you what a longer record tells you elsewhere on this site: how the building behaved in a downturn. Quadro has not been through one. Every figure here describes a market that has been broadly rising since the building existed, and nothing in the record distinguishes a well-built asset from a lucky vintage. That distinction usually takes fifteen years of county data to make, and here there are five.
Why there is no four-year change on this page
| Year | Qualified sales | Median price | Median $/sq ft | Median size |
|---|---|---|---|---|
| 2023 | 8 | $612,500 | $849 | 778 sq ft |
| 2024 | 9 | $550,200 | $687 | 801 sq ft |
| 2025 | 9 | $690,000 | $750 | 1,021 sq ft |
| 2026 to date | 3 | $512,500 | $656 | 781 sq ft |
Four years, 8, 9, 9 and 3 qualified sales. The per-foot column reads $849, $687, $750, $656 — down, up, down — while the median size sold goes 778, 801, 1,021, 781 square feet. On single-digit samples with a moving mix, that pattern is noise, and any four-year percentage computed from it would be a number dressed up as a finding.
So the Miami Condo Index shows no four-year change for Quadro, and neither does this page. What I can give you is the level: across all 29 sales in four years the median was $736 per square foot, in a band from $582 to $944, at a median price of $590,000.
Where the evidence thins out
Three qualifications, and here they are the main event rather than the footnotes.
The building is too new for the questions this site normally answers. Five years of record, one sell-out, 37 resales. There is no crash in this data because there has not been one since the building opened.
Turnover is low — about one home in 27 per year. That is unremarkable for a recently delivered building where most owners are the original buyers, but it means the four-year table will stay thin for some time yet.
Age, storeys, amenities, the commercial tenant and monthly costs are not in this record and are not stated here. Given that one commercial folio holds 13.3665% of the common elements, the declaration and the association’s budget matter more here than in most buildings, and neither is in the Property Appraiser’s data.
Who this building suits
It suits a buyer who wants a straightforward, checkable purchase. The uniformity is the feature: a four-year median of $736 per square foot at a median price of $590,000, in a building where the assessed values span only 1.9 times end to end, means the comparable you are shown is genuinely comparable.
It suits a Design District buyer who wants a newer home at a Biscayne Boulevard address rather than a bayfront one, and who is buying the location as much as the building.
It suits a buyer looking for evidence of resilience poorly, through no fault of the building. There is not enough record yet. If a long, tested ownership history is what you want, this site has buildings with fifty years of it and this is not one of them.
It suits a bargain hunter poorly for the same structural reason the uniformity helps everyone else: there is no low end here to find.
If you are selling, your strongest ground is that a buyer cannot easily argue you down by pointing at a different class of home — there isn’t one. Your weakest is volume: with 9 sales in 2025 and 3 so far in 2026, a buyer’s agent can reasonably say the market here is too thin to price precisely, and on this record they would be right.
Verified 19 August 2026 against the Miami-Dade County Property Appraiser record for 3900 Biscayne Boulevard, Miami — all 200 folios retrieved individually on 17 August 2026, grouped by subdivision and filtered to residential homes. Excluded from every figure: one reference folio and one commercial folio of 25,504 sq ft, whose 13.3665% undivided interest is reported in the body because it is material to ownership. Sale figures are qualified, arm’s-length transactions only; the sell-out cohort analysis counts only transactions flagged qualified by the county AND above $10,000, so foreclosure, deed-in-lieu and nominal transfers are excluded. No four-year change is published for this building: the four years rest on 8, 9, 9 and 3 sales and the median size of the home sold varies materially between them. Building age, storey count, amenity detail, the declaration’s voting provisions and association costs are omitted: no primary source has been confirmed for them. Re-check when the next tax roll publishes.
Quadro — Frequently Asked Questions
What makes Quadro unusual?
Its uniformity. The 2026 assessed values run $371,943 to $707,066 — a spread of 1.9 times, the tightest of any building in my Miami Condo Index. Heated area runs only 479 to 1,162 square feet, there is no penthouse tier, and 198 homes are spread across 36 floorplates with no plate covering more than 11 homes.
Why does that matter to a buyer?
Because it removes most of the room in a price argument. In a building spanning 500 to 5,000 square feet a seller can always point to a different class of home to justify a number. Here the comparable is a home very much like the one you are looking at. The flip side is that there is no bargain tier — the cheapest home in the building is assessed at $371,943.
How many units are in Quadro?
The county records 200 folios at 3900 Biscayne Boulevard: 198 residential homes, one reference folio and one commercial unit. The residential mix is 121 one-bedrooms, 65 two-bedrooms and 12 studios, with heated area from 479 to 1,162 square feet and a median of 780.
What is the commercial unit at Quadro?
A single folio of 25,504 square feet, assessed at $4,004,128, carrying 13.3665% of the undivided interest in the common elements — more than an eighth of the building. The 198 homes share about 86.6% between them. On any matter decided by ownership percentage that is a significant holding, and any buyer should read the declaration, which is not part of the county record.
Are prices rising at Quadro?
There is not enough evidence to say, and I am not going to pretend otherwise. The four years rest on 8, 9, 9 and 3 qualified sales, and the median size of the home sold moves between them — 778, 801, 1,021 and 781 square feet. Any four-year percentage from that would be noise. The level, across all 29 sales, is a median of $736 per square foot at a median price of $590,000.
Did the original buyers make money?
Mostly, on a small sample. 30 of the 2021 sell-out buyers have resold in a qualified arm’s-length transaction; 3 — 10.0% — sold for less than they paid, at a median outcome of +19.9%. The sell-out priced at a median of $673 per square foot.
How long is the sales record here?
Short. It begins in 2020 and holds 232 qualified sales, of which 169 are the 2021 sell-out. There are only 37 resales so far, at a median hold of 3.0 years. The building has not been through a downturn, so nothing in this record shows how it behaves in one.
