A buyer comparing towers on the Acqualina campus will notice the same pattern almost immediately: the newer the building, the higher the price per square foot. What that buyer usually assumes next is wrong. The higher price does not come with a faster sale. It comes with a slower one.
Over the trailing year through August 2026, condos at the original Acqualina Resort & Residences tower at 17875 Collins Avenue changed hands at an average of roughly $1,385 to $1,852 per square foot, with sales closing in 126 to 170 days and a list-to-sell ratio of 93 to 95 percent. Over the trailing year through May 2026, condos at The Estates at Acqualina, the twin 50-story towers delivered in 2022 and 2023, sold at $2,074 to $2,787 per square foot, took an average of 322 days or more to close, and settled at a 90 percent list-to-sell ratio. The newer product costs roughly $700 to $1,000 more per square foot and sits on the market nearly twice as long.
That gap is worth sitting with, because it contradicts the instinct most buyers bring to a new-construction luxury campus: that newer means faster, and higher price means higher demand. At Acqualina, the opposite is happening in the resale data. The building asking the most per square foot is also the one taking the longest to find a buyer.
What The Extra $700 A Foot Isn't Buying
Here is the detail that makes this comparison unusual rather than generic. All four towers on the Acqualina campus, the original Resort & Residences, the Mansions, and both Estates towers, share the same amenity infrastructure: the Villa Acqualina amenity center, the ESPA-branded spa, the attended private beach service, and the same restaurant lineup, including Il Mulino New York, A.Q. Chop House, and Costa Grill. A buyer at the Estates isn't purchasing access to a better pool deck or a private restaurant the original tower's owners can't use. The service layer is the same across the whole assemblage.
So the premium isn't buying amenities. It's buying three things that are genuinely different building to building: larger average floor plates (Estates residences run from roughly 3,800 to over 10,000 square feet under air, compared to the original tower's smaller two-bedroom and mid-size layouts that anchor its lower end), fewer units per floor (a maximum of two residences per floor in the Estates North tower versus a denser mix at the original tower), and construction that is roughly sixteen years newer.
That last point matters more than it sounds, and it's the piece most comparisons miss entirely.
The One Line Item That Isn't Shared
The original Acqualina tower was built in 2006. According to Rimkus, coastal condominium buildings within three miles of the shoreline must complete a Phase 1 structural milestone inspection by December 31 of the year they turn 25.
This doesn't mean the original tower has a structural problem. Nothing in the research available on the building suggests deterioration, and the tower's operators have described it as having stayed ahead of its capital and reserve obligations.
Reading The Days-On-Market Number Correctly
The instinct is to read 322 days on market at the Estates as a warning sign and 126 to 170 days at the original tower as evidence of stronger demand. That's too simple. A newer, higher-priced tower with fewer transactions naturally has thinner comparable sales data, which makes both buyers and sellers slower to agree on a number. The original tower has had two decades of closed sales to establish pricing consensus, which is part of why its list-to-sell ratio runs a few points higher and its time to close is shorter. The Estates towers are still building that same pricing history.
There's also a loyalty pattern worth noting here, because it explains part of the original tower's continued strength even as its per-square-foot price trails the newer product. A meaningful share of buyers at the Mansions at Acqualina, the 2015 tower on the same campus, previously owned at the original Acqualina Resort & Residences tower. That's an upgrade path within the same brand, not a flight away from the older building. The original tower isn't losing residents to the newer towers so much as feeding them.
The Numbers Side By Side
| Acqualina Resort & Residences (2006) | The Estates at Acqualina (2022-23) | |
|---|---|---|
| Avg. price per sqft (trailing 12 mo.) | ~$1,385-$1,852 | ~$2,074-$2,787 |
| Avg. days on market | 126-170 | 322+ |
| List-to-sell ratio | 93-95% | 90% |
| Typical residence size | ~2,200-6,000 sqft | ~3,800-10,000+ sqft |
| Units per floor | Up to six | Two (North Tower) |
Median list price at the original tower moved from $3,794,950 in September 2025 to $4,750,000 in September 2026, a jump of roughly 25 percent year over year. That's not a building losing ground. It's a building whose lower entry point is closing the gap even as it stays the faster, more liquid seller on the campus.
What This Actually Means For A Buyer
If speed of resale and a shorter negotiation window matter to your plans, the original tower's track record is the stronger data point, even at a lower headline price per square foot. If floor plate size, fewer neighbors per floor, and a longer runway before the next structural inspection cycle matter more, the Estates premium buys those things specifically, not a better version of the same amenities.
Neither answer is a mistake. They're two different products wearing the same brand name, priced according to two different sets of tradeoffs. A buyer who understands that the premium is paying for size and structural age, not for a nicer pool or a better table at dinner, is negotiating from a much stronger position than one comparing headline price per square foot alone.
Frequently Asked Questions
Does the price gap mean the original tower is undervalued? Not necessarily. The lower price per square foot reflects a building with two decades of sales history and an approaching structural inspection cycle, both of which are priced in. It's a different risk and reward profile, not a discount on the same product.
Why does a newer, more expensive building take longer to sell? Fewer closed comparable sales at that price tier make both sides slower to agree on value. As more Estates transactions close, that gap in days on market is likely to narrow.
