Building overview
The 66-story tower sits at 300 Biscayne Blvd Way, at the mouth of the Miami River, developed by G&G Business Developments under the Coto family and designed by Luis Revuelta with Bodas-Miani-Anger (BMA), who also handled the Aston Martin branded interiors and amenity floors, according to Miami Condo Investments. Units run from 698 to 18,811 square feet across one- to five-bedroom layouts, duplexes, and penthouses.
Most listing sites, including the developer’s, cite 391 residences. Miami Condo Investments states that Miami-Dade property tax records show 392 units and that it confirmed the figure with the building’s management office. Neither the developer’s page nor a direct property-appraiser search was independently verifiable for this article, so the discrepancy is reported here as unresolved instead of picked one way. A buyer can settle it in minutes by pulling the folio directly from the Miami-Dade Property Appraiser rather than trusting either marketing site.
Is Aston Martin Residences 391 or 392 units? Sources disagree. Most brokerage and developer pages say 391; one resale site cites property tax records showing 392. Check the Miami-Dade Property Appraiser folio for the building before relying on either figure in an offer.
Pricing and current market activity
Trailing-year MLS data from ZFC Real Estate, as of March 2026, shows 21 closed sales at an average asking price of $2,549,181 and an average sold price of $2,245,619, an 88% list-to-sell ratio, and an average of 148 days on market. Listed inventory at any given moment has run from 40 to 54 units for sale and 19 to 29 for rent across recent brokerage snapshots, which matters because the developer announced the building 97% sold in 2023, and a report cited on the building’s Wikipedia entry put it at 99% sold by May 2024, with only the triplex penthouse left. Those figures describe developer inventory at one moment. The active resale and rental market today is meaningfully larger than “one unit left” would suggest, because owners who bought pre-construction are now listing.
The unit that never fully left the spotlight is the triplex “Unique” penthouse on floors 63 through 65, roughly 19,868 square feet, marketed for years bundled with the final Aston Martin Vulcan ever built, a track-only, roughly 800-horsepower car originally priced near $2.3 million at its 2015 debut, per Robb Report. Asking price on the bundle has been reported between $50 million and $59 million depending on the listing year, most recently near $59 million per Francis York. Its current sale status should be reconfirmed before quoting it, since availability on a single trophy unit changes fast.
| Market segment | Approximate count | Price / rent | Source, date |
|---|---|---|---|
| Active for-sale listings | 40 to 54 units | List prices generally $875,000 to $75,000,000 | Zilbert, ZFC (2025 to 2026 snapshots) |
| Active for-rent listings | 19 to 29 units | Long-term rent from about $5,200 to $5,500/month | Miami Rental Solution, Apartments.com |
| Closed sales, trailing year | 21 | $1,269/sq ft average, 148-day average days on market | ZFC Real Estate, March 2026 |
Read together, these three rows show a building with real turnover, not a frozen, sold-out tower: the “sold out” framing describes 2023 to 2024 developer inventory, while the trailing-year sales column shows an active secondary market moving at a pace comparable to, or faster than, its named peers below.
What the HOA fee is actually funding
At roughly $1.70 per square foot, a 1,200-square-foot residence carries about $2,040 a month in association dues before taxes or insurance. What that fee has to cover changed permanently after the 2021 Champlain Towers South collapse. Florida Statute 718.112(2)(g), enacted through Senate Bill 4-D and amended by SB 154 and HB 913, bars condo associations from waiving or underfunding reserves for structural items, roofing, plumbing, electrical, and waterproofing, for any budget adopted on or after December 31, 2024, according to the DBPR Division of Condominiums. That prohibition took effect regardless of whether the association had completed its Structural Integrity Reserve Study; the study deadline itself was extended to December 31, 2025.
The detail buyers of new-construction towers routinely miss, per Haber Law’s reading of the statute: the SIRS clock is generally tied to when a building’s association passes from developer to unit-owner control, not to the building’s age. A tower delivered in 2024 or 2025 is not automatically on the same reserve-funding timeline as a building three blocks away that has been owner-controlled for decades. Whether turnover has occurred here and whether an initial SIRS has been filed could not be confirmed through public search for this article. It is exactly the kind of document a buyer’s attorney requests before closing, and its absence from every marketing page reviewed is the single biggest gap in what’s publicly available about this building.
Has the building’s structural reserve study been completed? Not confirmed publicly. Ask the seller directly for the SIRS report, the most recent reserve-fund balance, and the date of developer-to-owner turnover before making an offer.
Is the Aston Martin name worth the premium?
On trailing-year MLS data, this building sells above two comparable Downtown and Edgewater waterfront towers tracked with the same methodology, and it does so while moving faster.
| Building | Units | Avg $/sq ft, trailing year | Avg days on market | Closed sales, trailing year |
|---|---|---|---|---|
| Aston Martin Residences | 391 (disputed) | $1,269 | 148 | 21 |
| Missoni Baia | 249 | $977 | 180 | 16 |
| One Thousand Museum | 84 | $1,063 | 543 | 3 |
Sources: ZFC, Aston Martin Residences, ZFC, Missoni Baia, ZFC, One Thousand Museum.
The premium over Missoni Baia runs about 30%, and over One Thousand Museum about 19%, on this dataset. The bigger signal is liquidity: One Thousand Museum’s 543-day average sits well outside a normal marketing window, largely because very few, very large units trade at all in a given year. Despite having by far the largest unit count of the three, Aston Martin Residences still cleared 21 sales in the same window at a faster average pace than either peer. Scale and brand name did not slow this building down the way conventional wisdom about branded-residence scarcity might predict.
How does its price per square foot compare to peer towers? About 30% above Missoni Baia and 19% above One Thousand Museum on trailing-year MLS data, while also moving faster in days on market than either.
Rental yield and how fast units actually move
Using the smallest published unit size, 698 square feet, at the trailing-year average of $1,269 per square foot puts a purchase price near $886,000. Long-term rent listings for comparably sized units start around $5,200 a month, per Miami Rental Solution.
| Line item | Figure |
|---|---|
| Purchase price (698 sq ft × $1,269/sq ft) | ≈ $886,000 |
| Monthly rent (published floor) | $5,200 |
| Annual gross rent | $62,400 |
| Gross yield | ≈ 7.0% |
| Monthly HOA (698 sq ft × $1.70/sq ft) | ≈ $1,187 |
| Yield after HOA, before tax and insurance | ≈ 5.4% |
That 5.4% figure omits property tax and insurance, so it is a ceiling. A buyer running this math on a larger or higher-floor unit should expect the ratio to compress, since price per square foot rises with floor and view faster than achievable rent typically does at this price tier.
Is this a good rental investment? The smallest units pencil out to roughly 5% net of HOA before tax and insurance, using current MLS pricing and published rent floors. Larger, higher-floor units usually yield less, since price per square foot rises faster than rent per square foot.
Financing and insurance friction
Non-warrantable condo financing, elevated Florida property-insurance costs, and foreign-national buyer constraints all apply to new-construction Miami towers generally, and this building draws a strong international buyer base by every source reviewed. Building-specific loan terms or insurance premiums for this association were not found in public search for this article; request the association’s current insurance certificate and declarations page directly from the listing agent rather than relying on marketing copy.
Common mistakes before signing
- Comparing $/sq ft without adjusting for floor and view. A ground-floor river unit and a 60th-floor bay unit are not the same asset even inside the same building.
- Assuming “sold out” means no inventory. Dozens of resale and rental listings are active; “sold out” describes the developer’s original allocation, not today’s market.
- Not confirming the minimum lease term. Association rental policies vary by building and change with board votes; get it in writing rather than from a listing description.
Amenities and residence features
Interiors carry 10- to 12-foot ceilings, floor-to-ceiling glass, European cabinetry with Gaggenau appliances, and marble flooring throughout, features described in near-identical wording across most brokerage pages because they draw on the same developer materials. The distinguishing amenity floors sit on levels 52 through 55: a two-level fitness center, spa, art gallery, infinity pool, and a private superyacht marina with a rooftop helipad above.
Location and neighborhood fit
The building sits at the Miami River’s mouth, a walk from Brickell City Centre and Mary Brickell Village, about 15 minutes from Wynwood and 18 from South Beach by car.
Who this building actually suits
An end-user buying for lifestyle gets marina access and a Brickell-adjacent address that few other towers combine. An investor chasing yield should run the unit-specific math above before assuming the brand name guarantees a return; the smallest units are the only ones that currently pencil out well. A pied-à-terre buyer planning to rent seasonally should confirm the association’s minimum lease term directly, since short-term rental policy varies by building and can change with a board vote.
What this page can’t verify
Litigation history, the exact current reserve-fund balance, and the precise turnover date require condo-document access this article did not have. Treat every figure above as a starting point for due diligence, not a substitute for it.
