Key Takeaways
- This is the most uniform building I have measured anywhere — all 36 homes fall between 1,376 and 1,576 sq ft — a spread of 14.5% — and every one of them is a two-bedroom. The next tightest building in my index runs 19.6%, and most run past 80%.
- The county assesses every home within a factor of 1.3 — $585,631 to $784,507, median $644,948. That is the narrowest assessment range in the whole index, and it means the tax roll is telling you almost nothing about which home is which.
- Six qualified sales in four years, and none at all in 2025 — about one home in 24 a year, exactly the median across the buildings in my Miami Condo Index.
- The most recent sale is the highest per-foot price of the last four years — $905,000 on 12 May 2026 for a 1,376 sq ft home — $658 per square foot, against a four-year median of $612.
- The record is $1,024,700 — paid on 3 January 2022 for a 1,532 sq ft home — $669 per square foot, the building’s highest total price.
- A third of the building changed hands in 2022 — 13 qualified sales that year at a median $948,300, or $619 per square foot. It has been quiet since.

What is actually in the building
The county returns 36 folios for 1100 100th Street, and every one of them is a home — no reference folio, no commercial unit, no separately deeded parking, cabana or storage. That alone is unusual.
What is more unusual is what is in them. All 36 homes are two-bedrooms, and they run from 1,376 sq ft to 1,576 sq ft — a spread of 14.5% between the smallest and the largest. Twelve homes measure 1,463 sq ft, and the rest are grouped in sixes at 1,376, 1,377, 1,532 and 1,576.
For 2026 the county assesses the homes between $585,631 and $784,507, median $644,948. That is a range of 1.3 times — the narrowest of any building in my Miami Condo Index. At most addresses the equivalent figure is three to ten times.
What is left to price when every home is the same?
This is why a 36-home building is worth writing about.
Across the buildings I have pulled folio by folio from the county record, the tightest size distribution I had previously found was 19.6%, at The Tiffany of Bal Harbour. Most buildings run past 80%, and several past 400%. Bay Harbor One runs 14.5%, and unlike Tiffany it has no bedroom variation either — every home is a two-bedroom.
The practical consequence is unusually clean. In most buildings, the first and hardest question about a comparable is whether it is the same kind of home as yours. Here it always is. Any qualified sale in this building is a usable comparable for any home in it, which is worth real money in a negotiation and almost never true elsewhere.
What remains, once size and layout are removed, is floor, outlook and condition — and the record suggests those matter less here than at most addresses. The six sales of the last four years span $547 to $658 per square foot, a range of just 1.2 times. At The Tiffany of Bal Harbour, on similarly uniform homes, the equivalent four-year band was 2.2 times. At Bay Harbor One the homes are alike and so are the prices.
The one thing the uniformity takes away is information from the tax roll. With every home assessed inside a 1.3-fold range, a county assessment here cannot tell you whether you are looking at a good home or a poor one. You have to see it.
The price record
| Year | Qualified sales | Median price | Median $/sq ft |
|---|---|---|---|
| 2023 | 3 | $888,000 | $618 |
| 2024 | 2 | $800,600 | $547 |
| 2025 | No qualified sales | ||
| 2026 to date | 1 | $905,000 | $658 |
Six qualified sales in four years, and 2025 produced none. No four-year change is published for this building and it carries a dash in my Miami Condo Index. On samples this small I would not draw a line through the yearly medians, and the drop to $547 in 2024 rests on two transactions.
What the record supports is a level and a narrow one: a median of $612 per square foot across the six sales, in a band from $547 to $658, at a median price of $869,000. The single 2026 sale, at $658 per square foot, is the highest of the six, and it is the most recent evidence the building has.
Turnover is one home in 24 a year — exactly the median across the buildings in my Miami Condo Index, which for a 36-home building means roughly one and a half sales a year and long stretches with nothing.
The record is $1,024,700, paid on 3 January 2022 for a 1,532 sq ft home — $669 per square foot, which is also the building’s highest per-foot price. 2022 was the building’s year: 13 qualified sales, more than a third of the building, at a median $948,300 or $619 per square foot. Nothing like that volume has happened before or since.
On the ownership record there is less to go on than at most addresses, and I would rather say so than over-read it. The county shows 12 resales. Three lost money — 25.0% — at a median outcome of +8.8% over a 1.4-year hold. The median loss was 7.4% and the worst was 11.5%. Twelve transactions is not a basis for a confident statement about a building, but two things are worth noting: the holds have been short, and the losses have been shallow — nothing here has gone badly wrong.
Who this building suits, and who it does not
It suits a buyer who wants a two-bedroom on Bay Harbor Islands and wants to be able to check the price. Thirty-six near-identical homes means every sale in the building is your comparable, and the four-year band is only 1.2 times wide.
It suits a buyer who values a small, consistent building over a large one with a range of product. There is no studio tier here, no penthouse premium, and no floorplan that trades differently from yours.
It suits badly anyone who needs to sell on a timetable. One home in 24 a year across 36 homes means the building went through the whole of 2025 without a transaction.
It suits badly a buyer who wants something distinctive, or anything other than a two-bedroom of about 1,450 sq ft. The building does not have it.
If you are selling here, the useful facts are few but strong. Your comparables are the six sales of the last four years, all of them homes essentially identical to yours, running $547 to $658 per square foot — and the most recent, in May 2026, is the top of that range at $658. Price to that rather than to the 2024 pair at $547 and $548, which are the two lowest prints in four years and will be the first thing a buyer’s agent finds. And be realistic about time: this building recorded no sales at all in 2025.
Verified 18 August 2026 against the Miami-Dade County Property Appraiser record for 1100 100 St — all 36 folios retrieved individually, grouped by subdivision and filtered to residential homes. Every folio at this address is a dwelling: there is no reference folio, commercial unit, or separately deeded parking, cabana or storage. Sale figures are qualified, arm’s-length transactions only, with bulk/portfolio transfers collapsed to a single transaction. 2025 records no qualified sales at this address and 2026 carries one, so no four-year change is published. Comparisons of size and assessment uniformity are against the buildings I have pulled folio by folio from this same source, not against the whole market. Assessed values are the county’s, not market valuations. Building age, storey count, architect and amenity detail are omitted: no primary source has been confirmed for them. Re-check when the next tax roll publishes.
Bay Harbor One — Frequently Asked Questions
How big are the homes at Bay Harbor One?
All 36 homes are two-bedrooms between 1,376 and 1,576 sq ft, median 1,463 — a spread of just 14.5% between the smallest and largest. It is the most uniform building I have measured; the next tightest in my index runs 19.6%.
How much does a home at Bay Harbor One sell for?
Across the six qualified sales in the four years to August 2026 the building cleared a median $612 per square foot, in a band from $547 to $658, at a median price of $869,000. The most recent sale, in May 2026, was the highest of the six at $658 per square foot.
Have prices at Bay Harbor One gone up or down?
The record will not say. There have been six qualified sales in four years and none at all in 2025, so no four-year change is published and the building carries a dash in my Miami Condo Index. The 2024 median of $547 per square foot rests on two transactions and the 2026 figure on one.
How often do homes at Bay Harbor One change hands?
The county records six qualified sales in the four years to August 2026 against 36 homes — about one home in 24 a year, exactly the median across the buildings in my Miami Condo Index. In a 36-home building that means roughly one and a half sales a year, and 2025 had none.
What is the highest price ever paid at Bay Harbor One?
$1,024,700, on 3 January 2022, for a 1,532 sq ft home — $669 per square foot, which is also the building’s highest price per square foot. 2022 was the building’s busiest year by far, with 13 qualified sales at a median $948,300.
Have owners at Bay Harbor One made money?
On a small sample, mostly. The county records 12 resales, of which three lost money — 25.0% — at a median outcome of +8.8% over a 1.4-year hold. The median loss was 7.4% and the worst 11.5%, so nothing here has gone badly wrong, but twelve transactions is not a firm basis for a conclusion.
Why does the uniformity of this building matter?
Because it removes the hardest question about any comparable. In most buildings you have to establish whether a recent sale was the same kind of home as yours. Here it always was — 36 two-bedrooms within 14.5% of each other in size — so any sale in the building is directly usable, and the four-year price band is only 1.2 times wide as a result.
