Over the recorded series, Mariner Apts’s median sold price moved from $227,500 (2014) to $380,000 (12 months ending 2026-09-20) — +67% over that span, with every year’s figure from recorded closings, not a model.
The recorded series starts in 2014 at $227,500. The 2020–22 run-up did what it did everywhere — Mariner Apts’s median moved +81% from 2019 to 2022. Against the 2024 peak of $457,500, the current median stands at -17%. Annual sales volume here has ranged from 1 to 13 closings a year (10-yr average 6.9). With roughly 6.9 closings a year, Mariner Apts’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.
Of the 17 recorded Mariner Apts closings since 2024, half landed between $390,000 and $450,000 (the middle two quartiles); the lowest recorded sale was $350,000 and the highest $495,000. If your home sits outside the middle band, the reason usually shows up in the size table below before it shows up in condition.
| Sold price band | Share of closings | Sales |
|---|---|---|
| Under $350,000 | 0 (0%) | |
| $350,000 – $391,667 | 5 (29%) | |
| $391,667 – $433,333 | 6 (35%) | |
| $433,333 – $475,000 | 3 (18%) | |
| None and up | 3 (18%) |
The same recorded closings, split into thirds by living area. Find the row your home falls in: the $/sqft figure times your square footage is the recorded-sales bracket for homes like yours here — a starting range from real closings, not a valuation of your specific property. Larger homes here have been selling at a higher price per square foot than smaller ones ($553 vs $455) — less common, and usually a sign of newer or upgraded product at the top of the range.
| Size group | Median $/sqft | Median sold | Sold range | Sales |
|---|---|---|---|---|
| Smaller homes 814–814 sq ft | $455 | $370,000 | $350,000 – $423,000 | 5 |
| Mid-size homes 814–814 sq ft | $527 | $429,000 | $390,000 – $442,500 | 5 |
| Larger homes 814–814 sq ft | $553 | $450,000 | $377,500 – $495,000 | 7 |
At Mariner Apts’s $380,000 median and Collier County’s adopted 11.05 mills (FY2025-26), a home assessed at that price carries roughly $4,200 a year in property tax before exemptions, or about $3,760 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 Collier County tax page.
Current asking prices run a median $387,700 against the $380,000 recorded sold median (+2%) — the gap between what sellers hope and what the record shows. Demand check: 25% of Mariner Apts’s listings are under contract, against 16% for ZIP 34145 and 19% for Collier County as a whole — the community is absorbing faster than its surroundings. Momentum’s market-heat index for Mariner Apts reads 29/100 (computed from DOM, sale-to-list, and absorption; 2020–21 peaked in the 70s here).
Asking and recorded sold prices are within a few percent of each other here, so the table above is close to what a Mariner Apts buyer will actually pay; the spread on any single home comes down to size, condition and timing.
