Over the recorded series, MARINER BAY’s median sold price moved from $212,500 (2012) to $440,000 (12 months ending 2026-08-10) — +107% over that span, with every year’s figure from recorded closings, not a model.
The recorded series starts in 2012 at $212,500. The 2020–22 run-up did what it did everywhere — MARINER BAY’s median moved +58% from 2019 to 2022. Against the 2024 peak of $649,000, the current median stands at -32%. Annual sales volume here has ranged from 1 to 13 closings a year (10-yr average 6.7). With roughly 6.7 closings a year, MARINER BAY’s medians move in steps, not curves — a handful of unusual sales can swing a year, which is why the sales count sits next to every figure above.
From the live MLS feed as of 2026-09-03: The homes listed or recently sold were built between 2003 and 2005 (median 2005); 9 of 9 listed or recently sold homes report an HOA, median $740/mo; none of the 9 geocoded listed or recently sold homes sits in a FEMA special flood hazard zone (median elevation 7 ft); the features listings here most often name are Clubhouse, Fitness Center, Pool, Boating, Sauna and Gated - No Guard.

At MARINER BAY’s $440,000 median and St. Lucie County’s adopted 22.85 mills (FY2025-26), a home assessed at that price carries roughly $10,060 a year in property tax before exemptions, or about $9,080 with the full Florida homestead exemption — a buyer’s first-year figure; a long-time owner’s Save Our Homes cap can be far lower, which is one reason resale taxes jump at closing. Municipal and special-district millage varies inside the county; see the St. Lucie County tax page.
Current asking prices run a median $460,000 against the $440,000 recorded sold median (+5%) — the gap between what sellers hope and what the record shows. The market is carrying about 6 months of supply at the current sales pace. Demand check: 25% of MARINER BAY’s listings are under contract, against 14% for ZIP 34949 and 24% for St. Lucie County as a whole — the community is absorbing faster than its surroundings.
Asking and recorded sold prices are within a few percent of each other here, so the table above is close to what a MARINER BAY buyer will actually pay; the spread on any single home comes down to size, condition and timing.
