Bay Harbor Islands New Construction Condos: Why Median Prices Shift

Ask three different sources what a home costs in Bay Harbor Islands right now and the answers won't agree with each other. In January 2026, one widely used housing tracker put the town's median sale price at $621,000, down nearly 19 percent from a year earlier, with homes selling in 118 days versus 220 the prior January. A separate tracker's trailing 12-month figure for the same town came in at $700,000, up 6 percent. A third put the median asking price at $897,000, up 6 percent month over month. None of these numbers is wrong. They're measuring different slices of a town so small that a single month's closings can swing the whole result.

Bay Harbor Islands sits on two barrier islands connected by a single causeway, with roughly 6,000 residents according to census estimates cited in CoStar coverage this spring. That scale is the whole story. In January 2026, only four single-family homes sold across the entire town, down from eleven the year before. A median built on four transactions isn't tracking a market. It's reporting whichever four houses happened to close that month, and in a town where a 1950s bungalow and a newly built estate can sit two blocks apart, those four houses rarely look anything alike.

A Town Where Ten Listings Span $31 Million

The spread shows up just as clearly on the sell side. As of March 2026, only ten single-family houses were listed for sale across the entire town, priced anywhere from $3.3 million to $34.5 million. That's not a market with a typical house and some outliers. It's two different housing stocks sharing a zip code: the West Island's mix of 1950s-era bungalows, Mediterranean Revivals and mid-century ranch homes sitting alongside brand-new construction on the same streets, sometimes the same block.

Layer in what's happening on the condo side and the picture gets more complicated, not less. By late September 2026, MLS inventory across the town's houses and condos combined stood at roughly 189 active listings. A meaningful share of that inventory sits inside buildings that didn't exist eighteen months ago, which means a buyer comparing "the median" across two different months isn't just seeing price movement. They're seeing the mix itself change as new supply lands.

Seven Buildings, One Overlapping Window

Bay Harbor Islands is in the middle of its most concentrated wave of new construction on record, and the timing is the part that matters. According to CoStar, THE WELL Bay Harbor Islands, developed by Terra Group with architecture by Arquitectonica and interiors by Meyer Davis, received its temporary certificate of occupancy in April 2026. The building delivers 66 residences alongside more than 22,000 square feet of wellness amenities, and sales launched at $1.2 million. By the time it opened, the residential component was 90 percent sold, and the building's 102,000 square feet of office space was 90 percent leased, including a lease to Tom Brady Enterprises.

A few blocks away, three more projects are moving through the same window on different timelines:

Bay Harbor Towers, developed by PPG Development and L3C Capital Partners, topped off in November 2025 and was tracking toward a third-quarter 2026 completion as of this spring, with just nine residences and two penthouses left to sell. Remaining units were priced from $2.6 million, penthouses from $10 million. La Baia South, a 68-unit building at 9201 East Bay Harbor Drive designed by Luis Revuelta Architecture, sold out completely and received its TCO in the fourth quarter of 2025, backed by a $90 million construction loan. It had launched near $800,000 per unit when presales opened in 2022 and 2023. Its successor, La Baia North, broke ground in October 2024 and secured a $67 million construction loan from S3 Capital in September 2025, reaching 75 percent presold ahead of a 2027 delivery.

Three more projects round out the wave at an even smaller scale. La Maré Signature Collection at 9781 East Bay Harbor Drive offers just nine residences, each with its own private pool, designed by Kobi Karp with interiors by Debora Aguiar. Its companion, La Maré Regency Collection at 9927 East Bay Harbor Drive, was targeting second-quarter 2026 delivery. And at 9900 West Bay Harbor Drive, a seven-story, 23-residence building developed by The Horizon Group topped off in December 2025 with a summer 2026 completion target.

Seven separate buildings, ranging from 9 units to 68, all converging on delivery within roughly the same eighteen-month window in a town this size. That concentration is what's actually driving the pricing confusion, not a shift in what buyers are willing to pay.

The Comps Problem Hiding Behind "Sold Out"

When a lender orders an appraisal for a unit inside a building with no resale history, the appraiser has to pull comparables from somewhere else, often from an older building with different finishes, a different amenity budget, and a different HOA structure. That's a routine friction point in any new-construction closing, but it compounds here because so many of the comparable buildings are equally new. A unit at THE WELL, where wellness infrastructure is spread across 66 owners, doesn't appraise the same way as a nine-unit building like La Maré Signature, where each owner is carrying a proportionally larger share of shared amenities and each has a private pool. Buyers financing a purchase in any of these buildings should expect the appraisal conversation to take longer than it would in an established building with a decade of resale data behind it.

The projects behind those appraisal comparisons also involve substantial financing. THE WELL secured a $238 million refinancing loan from Eldridge Real Estate Credit and Hudson Bay in late 2025. La Baia South closed on $90 million, La Baia North on $67 million.

What's Actually Left to Buy

The remaining inventory in this cycle isn't evenly distributed. Bay Harbor Towers has nine residences and two penthouses left in a building that's already 75 percent sold and effectively complete. La Baia North still has a quarter of its units available ahead of a 2027 delivery, which gives a buyer more runway before closing costs come due. The La Maré collections operate at a different scale entirely: nine and a small handful of units respectively, which makes them the rarest product on the island regardless of price point.

Buyers weighing new construction against the West Island's older stock are comparing two different ownership experiences, not just two different price tags. A 1950s home rebuilt over the decades carries none of the shared amenity structure, wellness programming, or HOA overhead that comes with a building like THE WELL. Neither is a better answer. They're just not the same product, which is exactly why a single town-wide median can't describe either one accurately.

Frequently Asked Questions

Does the new construction boom change what a West Island resale home is worth?

Not directly. The West Island's housing stock, built mostly from the 1950s onward with periodic rebuilds, trades on its own comparables, and the small number of annual sales there means each closing carries outsized weight in any median calculation. The new buildings along East and West Bay Harbor Drive are a separate market segment even though they share a zip code.

Is this kind of pricing confusion unique to Bay Harbor Islands?

The underlying math applies to any barrier-island town this size, though the scale of concurrent delivery here is unusual. Buyers comparing Bay Harbor Islands to other small luxury enclaves nearby should expect the same small-sample volatility wherever total annual transactions number in the dozens rather than the hundreds.

Seven buildings landing in overlapping windows means the next twelve months of closings will keep reshaping what "median" means here before the market settles into whatever comes after this cycle.
