Over the recorded series, The Dunes Sanibel Island’s median sold price moved from $770,000 (2017) to $967,000 (12 months ending 2026-09-20) — +26% over that span, with every year’s figure from recorded closings, not a model.
The recorded series starts in 2017 at $770,000. The 2020–22 run-up did what it did everywhere — The Dunes Sanibel Island’s median moved +88% from 2019 to 2022. Against the 2022 peak of $1,225,000, the current median stands at -21%. Annual sales volume here has ranged from 3 to 17 closings a year (10-yr average 9.1). With roughly 9.1 closings a year, The Dunes Sanibel Island’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 19 recorded The Dunes Sanibel Island closings since 2024, half landed between $852,500 and $1,150,000 (the middle two quartiles); the lowest recorded sale was $725,000 and the highest $1,880,000. If your home sits outside the middle band, the reason usually shows up in the size table below before it shows up in condition.

| $750,000 – $933,333 | 6 (32%) | |

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. Smaller homes here have been selling at a higher price per square foot than larger ones ($529 vs $437) — the usual pattern, since lot, kitchen and baths do not scale with floor area.
| Size group | Median $/sqft | Median sold | Sold range | Sales |
|---|---|---|---|---|
| Smaller homes 1,400–1,773 sq ft | $529 | $850,000 | $725,000 – $1,290,000 | 6 |
| Mid-size homes 1,783–2,065 sq ft | $520 | $999,500 | $735,000 – $1,300,000 | 6 |
| Larger homes 2,112–3,055 sq ft | $437 | $1,133,000 | $855,000 – $1,880,000 | 7 |
From the live MLS feed as of 2026-10-01: 8 active listings (plus 0 pending) asking from $499,000 to $1,595,000, median $1,195,000; 4 of 8 have been on the market over 60 days (median 61 days so far); the homes listed or recently sold were built between 1977 and 2016 (median 1982); 6 of 6 geocoded listed or recently sold homes sit inside a FEMA special flood hazard zone (A/V), which buyers’ lenders will price into insurance; median elevation 4 ft. For a seller this is the competition a buyer will tour alongside your home; for a buyer, the stale share is where negotiating room usually is. See the current The Dunes Sanibel Island listings →
At The Dunes Sanibel Island’s $967,000 median and Lee County’s adopted 15.97 mills (FY2025-26), a home assessed at that price carries roughly $15,440 a year in property tax before exemptions, or about $14,780 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 Lee County tax page.
Current asking prices run a median $1,095,000 against the $967,000 recorded sold median (+13%) — the gap between what sellers hope and what the record shows. Demand check: 0% of The Dunes Sanibel Island’s listings are under contract, against 9% for ZIP 33957 and 18% for Lee County as a whole — the community is currently absorbing slower than its surroundings, which is negotiating information. Momentum’s market-heat index for The Dunes Sanibel Island reads 19/100 (computed from DOM, sale-to-list, and absorption; 2020–21 peaked in the 70s here).
With asking prices running +13% over the recorded sold median, a The Dunes Sanibel Island listing priced against the closed record above stands out against its competition; one priced against the asking crowd joins the statewide list of homes that never sold.
