Sold Out in Ten Days, Resold for Years: The SeaGlass Jupiter Island Sales Record

Twenty-One Deeds in Ten Days

The building closed out in ten days. The Property Appraiser's record shows fourteen deeds on November 14, 2022, two on November 21 and five on November 23, one for each of the 21 residences. The prices were contract prices, set when buyers signed during construction, which is why they look like another era. The 01 line, the smallest plans at about 3,550 to 3,600 square feet, closed between $5.5M and $11.9M, with the penthouse at the top of that range. The 02 line closed between $6.6M and $7.9M. The 03 line, the largest plans at about 5,210 square feet, closed between $7M and $10.2M.

The developer took $168.8M across the 21 deeds, a median of $7.2M. Eight of the 21 residences carry a homestead exemption today, so thirteen are second homes or held through entities. The table lists every closing.

Five Resales, Every One Above Cost

Five residences have changed hands since, and all five are on the MLS, so the deed record and the listing record agree. The first two were flips. Unit 601 closed with the developer at $6.2M in November 2022 and resold in Mar 2023 at $10.7M. The gain was 70 percent in 4 months, at $2,964 a square foot. Unit 501 followed in May 2023 at $9.4M, 71 percent over its $5.5M contract price. Those two sales set the building's high mark.

The three resales since have closed lower per foot each time. Unit 403 sold in Nov 2023 at $2,399 a foot, unit 203 in Feb 2025 at $2,457, and unit 302 in Jun 2026 at $2,094. The gains over the developer's price narrowed the same way, from 71 percent to 20. Every resale closed in cash. Together the five brought $49.8M.

The Listings That Did Not Sell

The closings understate the time it takes to sell here. Seven residences have been listed on the MLS since the building opened, in 18 separate campaigns. Unit 403 first asked $19.8M in November 2022 and sold a year later at $12.5M, 63 percent of that original asking price. Unit 203 asked $12.9M in December 2022, was withdrawn twice, and sold in Feb 2025 at $9M. Unit 302 asked $11.9M in October 2023, expired twice, and sold in Jun 2026 at $8.2M.

Two residences have not sold at all. Unit 303 has been listed 3 times since October 2023, from $14M down to $10.5M, for 743 days, and is off the market. Unit 301 first asked $10.1M in July 2023 and is on the market today at $7.5M, $2,113 a foot, after 1,041 days across three listings. The table adds up every campaign.

What It Costs to Own

The association fees on the listings run from about $6,442 a month on the 01 and 02 lines to about $9,233 on the 03 line. That works out to 1.77 to 1.83 dollars a square foot each month. The tax bills quoted on the resold residences ran from $110,045 to $145,438 a year. A buyer at today's prices should expect the bill to reset to the purchase price. Our county property tax guide sets out how.

How to Read the Building

SeaGlass is the newest condominium on Jupiter Island and the only one of its kind on the island's southern beachfront. That is why the 2023 flips cleared so far above cost. The record since says two things. Resale prices per foot have come down each year as the first buyers' contract prices receded into history. Time on the market has run long for anyone asking the 2023 numbers. A buyer today is looking at $2,094 to $2,113 a foot on the evidence, a seller at the patience the 303 and 301 campaigns show. Both sides should read the deed record before the listing sheet. The building's page is our SeaGlass Jupiter Island listing page, and the wider island is on our Jupiter Island page.
