The Sunny Isles luxury market produced one of the biggest closings in South Florida in September 2026. A penthouse at The Estates at Acqualina, 17975 Collins Avenue, sold for $33 million, the second-largest sale of the month across Miami-Dade and Palm Beach counties, according to Haute Living’s September report.
September 2026 in Numbers
| Metric | September 2026 | Change from August |
|---|---|---|
| Closings of $3M+ | 94 | Up from 81 |
| Total volume | $645.4M | Up from $624.2M |
| Average sale | $6.87M | Down from $7.71M |
| Median sale | $4.50M | Down from $4.70M |
| Median price per sq ft | $1,431 |
Miami-Dade accounted for 59 closings and $387.3 million, about 60% of the total. Miami Beach led all markets with $178.5 million across 29 sales. Most deals, 81 of 94, closed between $3 million and $10 million, showing broad demand rather than a few record trades.
What the Sunny Isles Luxury Market Is Telling Buyers
A $33 million penthouse sale a few blocks south of 18801 Collins Avenue shows that the very top of the Sunny Isles luxury market is still deep. At the same time, the falling average and median suggest more activity in the $3 million to $10 million range, which is where most St Regis Sunny Isles residences sit.
For buyers comparing completed towers with new construction, the gap in price per square foot is worth noting. September’s South Florida median of $1,431 per square foot covers a mix of resale homes and condos, while the St Regis Sunny Isles north tower list runs about $2,700 to $3,133 per square foot for brand-new, branded product. Our prices page breaks down each layout.
Looking Ahead
The report notes 11 additional sales worth $211.8 million that had not yet appeared in county records, so final September totals may rise. For ongoing data, see the market updates on Miami Real Estate Trends.
Why Oceanfront Sunny Isles Keeps Drawing $3 Million+ Buyers
Several forces keep the Sunny Isles luxury market active. Florida has no state income tax, which continues to attract buyers relocating from high-tax states. Wealthy buyers from Latin America, Canada and Europe have long favored Sunny Isles Beach for its direct beach access, newer high-rise inventory and easy reach to both Miami and Fort Lauderdale airports. And the supply of true oceanfront land on the barrier island is limited, so new towers are rare.
Branded residences add another layer. Buyers increasingly pay for service programs, staff and amenities that a hotel brand operates, and they expect those programs to support long-term value. That is the segment where St Regis Sunny Isles competes.
Reading Monthly Sales Reports the Right Way
Monthly luxury reports are useful, but a single month can swing on a few large trades. A $33 million closing can lift the average sale price on its own, which is why the median is usually a better signal of what typical buyers are paying. Look for trends across three to six months, and separate condos from single-family homes, since they move differently.
Recorded sales also lag the market. Pre-construction contracts, like those at St Regis Sunny Isles, do not show up in county records until closing, which can be years later. That means monthly reports mainly describe the resale market and completed new buildings, not current pre-construction demand.
Sunny Isles Luxury Market Outlook for Buyers
For a buyer in the $3 million to $10 million range, the September data suggests healthy activity and enough deals to compare prices. Above $20 million, inventory is thin and each sale stands on its own. Buyers who want brand-new, branded product in the Sunny Isles luxury market have few options outside the towers now under construction, which supports firm pricing at the top.
Where St Regis Sunny Isles Fits in the Sunny Isles Luxury Market
Within the Sunny Isles luxury market, buildings tend to fall into three groups. The first is completed towers from the 2000s and 2010s, many with ocean views and resort amenities, now selling as resales. The second is the ultra-luxury completed buildings that set the record prices, such as Acqualina and its Estates. The third is new branded construction, where St Regis Sunny Isles sits alongside a handful of other towers on Collins Avenue.
Each group appeals to different buyers. Resales offer immediate occupancy and room to negotiate. Ultra-luxury completed buildings offer proven service and established resale values. New branded construction offers modern design, current building codes and a long payment timeline.
Practical Steps for Buyers This Quarter
Set a budget range, then ask our team for recent closed sales in the buildings you like, not just active listings. Compare price per square foot, monthly costs and building age across the three groups. With that comparison, the decision between a resale and a St Regis residence usually becomes much clearer, and you can act quickly when the right home appears in the Sunny Isles luxury market.
