Key Takeaways
- This is the most evenly built building I have measured — the homes divide into 102 two-bedrooms, 102 three-bedrooms and 102 four-bedrooms, and three floorplates carry 51 homes each. That symmetry is deliberate and it makes pricing here unusually clean.
- No four-year change is published and the building carries a dash in my Miami Condo Index — 2026 has recorded a single qualified sale. My threshold is five in both the opening and closing year.
- Current level is $1,706 per square foot — on 52 qualified sales over four years, in a tight band from $1,529 to $2,298, at a median price of $3,800,000.
- It sold out into 2019–21 and the ownership record is middling as a result — 375 sales closed in those three years. Of those original buyers who have resold, 23.2% sold at a loss, at a median gain of 15.2%.
- Its penthouse gained 71.0% in ten months — PH-04 sold for $7,250,000 on 8 June 2021 and again for $12,400,000 on 11 April 2022 — the highest price the county records here.
- More than half the building has never resold — 167 folios recorded a sale in the 2019–21 sell-out and have not traded since. Those owners’ outcomes are untested.

What is actually in the building
The county returns 323 folios at 18975 Collins Avenue. 308 are homes. Fourteen are deeded parking spaces the county labels PS-1 to PS-15 — there is no PS-13 — each of 209 sq ft, and one is a reference folio carrying no dwelling. All fifteen are excluded from every figure below — which matters more here than usual, because parking is separately deeded and, as I show later, sometimes conveyed with a home in the same transaction.
This is the most symmetrical building in my Miami Condo Index and it is worth pausing on. The 308 homes divide almost exactly into thirds: 102 two-bedrooms, 102 three-bedrooms, 102 four-bedrooms and two studios. Three floorplates carry 153 of them — 51 homes each at 2,271, 2,468 and 2,682 sq ft. Buildings do not usually come out this even, and the practical consequence is that almost every home here has fifty near-identical comparables.
The homes run from 1,080 sq ft to 5,336 sq ft, median 2,468. That median is the important number: this is a building of genuinely large homes, where the median residence is more than four times the size of the median home in several oceanfront towers I measure. 306 of the 308 sit at 3,504 sq ft or below; two penthouses at 4,821 and 5,336 sq ft sit above a 1,317 sq ft gap and should be read separately.
For 2026 the county assesses the homes between $1,309,354 and $9,777,600, median $3,078,241.
The price record
| Year | Qualified sales | Median price | Median $/sq ft |
|---|---|---|---|
| 2023 | 19 | $3,900,000 | $1,673 |
| 2024 | 19 | $4,000,000 | $1,763 |
| 2025 | 13 | $3,775,000 | $1,673 |
| 2026 to date | 1 | $2,600,000 | $1,699 |
Across four years that is 52 qualified sales, a median of $1,706 per square foot in a band from $1,529 to $2,298, and a median price of $3,800,000.
I am not publishing a four-year change for this building, and the table shows why: 2026 has recorded one qualified sale. One transaction is not a year. My rule is five qualified sales in both the opening and closing year before I will state a direction, and until this year fills in, the building carries a dash in my Miami Condo Index.
What the record does support, and supports well, is the level. Look at the price-per-foot column across 2023, 2024 and 2025 — $1,673, $1,763, $1,673, on 19, 19 and 13 sales. That is a remarkably steady building. The full four-year band runs from $1,529 to $2,298, which is one of the tightest ranges I hold; most buildings this size show a spread of three or four times, and this one shows less than 1.5. The symmetry of the floorplates is doing that work. When 153 homes sit on three layouts, there is very little for a price to disagree about.
Turnover runs at one home in 24 per year — exactly the median across the buildings in my Miami Condo Index.
One disclosure about the largest sales. The $8,000,000 paid for unit 5200 on 30 April 2024 conveyed a 209 sq ft parking folio, PS-7, in the same transaction. The price therefore covers two folios, and the $2,298 per square foot it implies for the home alone is slightly overstated. It is the top of my published band, so I would treat that ceiling as a touch generous rather than a clean comparable.
A young building with a short and unfinished record
375 qualified sales closed here across 2019, 2020 and 2021 — 86, 182 and 107 — which is effectively the whole building selling out in three years. Everything the county knows about ownership outcomes here has happened since.
| When they bought | Resales | Sold at a loss | Median outcome |
|---|---|---|---|
| In the 2019–21 sell-out | 151 | 23.2% | +15.2% |
| After 2021 | 12 | 8.3% | +6.0% |
| All resales | 163 | +13.7% median | 22.1% lost money |
A 22.1% loss rate is close to the middle of everything I measure, and for a building whose owners bought at 2019–21 prices that is a reasonable outcome rather than a good or bad one. The median reseller is up 13.7%. But I would treat all of this as provisional, because the record is young and heavily incomplete: 167 folios — more than half the building — sold once in the 2019–21 window and have never traded again. Their owners’ results are unknown and appear in none of the figures above. In older buildings I can lean on a thousand resales spanning three cycles; here I have 163 spanning five years and one direction of travel.
The two extremes show how much of the outcome came down to which home and which month. The best result is a 1,089 sq ft home bought for $1,035,000 on 7 January 2020 and sold for $1,800,000 on 31 March 2023 — up 73.9%. The worst is a 3,052 sq ft home bought for $4,450,000 on 7 February 2020 and sold for $3,200,000 on 22 February 2021, down 28.1% after twelve months. Both bought within a month of each other in the same building.
The building’s headline transaction is its penthouse, and it is a genuine outlier. PH-04, 4,821 sq ft, sold for $7,250,000 on 8 June 2021 and again for $12,400,000 on 11 April 2022 — up 71.0% in ten months, and the highest price on the county record for this address. I can tell you it happened; I cannot tell you why, and the record does not say. It is one transaction and nobody should price a home off it.
Who this building suits, and who it does not
It suits a buyer who wants a large oceanfront home and wants to know exactly what it is worth. That combination is rarer than it sounds. The median home here is 2,468 sq ft, three floorplates repeat 51 times each, the four-year price band is unusually narrow, and turnover sits right at the market median. If you are spending close to $4,000,000 and you want the comfort of fifty comparable sales rather than five, this building provides it.
It suits badly anyone who wants a track record. This building has one cycle of history and no downturn in it. More than half its homes have sold exactly once. Every ownership figure on this page rests on five years of a rising market, and I would not represent them as durable.
It also suits badly a buyer at the smaller end. There are two studios and the entry size is 1,080 sq ft — this is not a building where a compact home is an option.
If you are selling here, the symmetry is your best argument and your tightest constraint. You have roughly fifty identical homes to point at, which makes a well-supported price easy to defend — and equally makes an ambitious one easy to refute. Price inside the $1,529 to $2,298 band, discount the $2,298 ceiling because that sale carried a parking space with it, and be aware that 2026 has produced one sale so far: a buyer may reasonably argue there is no current market level, and on this record they would have a point.
Verified 19 August 2026 against the Miami-Dade County Property Appraiser record for 18975 Collins Avenue — all 323 folios retrieved individually, grouped by subdivision and filtered to residential homes, excluding fourteen deeded parking folios and one reference folio, along with cabana and storage. Sale figures are qualified, arm’s-length transactions only, with bulk/portfolio transfers collapsed to a single transaction; one 2024 sale conveying a parking folio alongside the home is disclosed on the page. 2026 is an incomplete year. Building age, storey count and amenity detail are omitted: no primary source has been confirmed for them. Re-check when the next tax roll publishes.

Are prices going up or down here?
I will not say, and that is deliberate. 2026 has recorded a single qualified sale, well below my threshold of five in both the opening and closing year, so the building carries a dash in my Miami Condo Index. The 2023–25 level was notably steady at $1,673, $1,763 and $1,673 per square foot.
How big are the homes?
Large. They run from 1,080 to 5,336 sq ft with a median of 2,468. Three floorplates — 2,271, 2,468 and 2,682 sq ft — account for 51 homes each.

Most have. Across 163 resales, 22.1% sold at a loss and the median owner was up 13.7%. Treat this as provisional: the building sold out in 2019–21 and 167 folios have never resold, so more than half of all outcomes are untested.
How quickly do homes here sell?
Turnover runs at about one home in 24 per year, exactly the median across the buildings in my Miami Condo Index.
What is the highest price ever paid here?
$12,400,000 for PH-04, a 4,821 sq ft penthouse, on 11 April 2022. The same home had sold for $7,250,000 ten months earlier, on 8 June 2021 — a gain of 71.0%. It is a single transaction and should not be used to price anything else.
