As of September 2026, the MLS records 44 closed sales in Chateaux Sur Mer Unrec in Sanibel, FL since 2014, the most recent in September 2026. Recorded prices since 2024 ran from $925,000 to $7,500,000 (median $3,460,000), on homes of 1,531 to 5,812 sq ft. At that median and Lee County's FY2025-26 rate of 15.97 mills, annual property tax runs about $55,260 ($54,590 with the full homestead exemption).
Chateaux Sur Mer Unrec is a small, low-turnover pocket on Sanibel with only 56 homes total, and the spread in construction years — from 1965 to 2021 — means condition and vintage do more to set price here than any single market trend. A median year built near 1978 tells you a meaningful share of the inventory is older construction, so buyers should expect anything from original-era homes to more recent rebuilds, with value driven largely by how much updating has been done.
With a homestead share of 41.2%, this is not a community dominated by owner-occupancy, and inventory can move in and out depending on ownership intent. Sellers here are competing less on neighborhood-wide comps and more on the specific condition and size story of their individual home — with living areas that skew large, a well-documented renovation history or clear scope-of-work disclosure matters more than in a typical subdivision.
The 60-Second Overview
Chateaux Sur Mer Unrec sits within Sanibel in Lee County as an unrecorded, low-density enclave rather than a platted subdivision with shared amenities — current MLS listings show no identified community amenities, so whatever a buyer gets here comes from the individual property, not a shared package.
Pre-construction details are compiled from public records, builder announcements and builder listings, and are subject to change without notice; figures are deemed reliable but not guaranteed.

Who Chateaux Sur Mer Unrec is best for.
Best for

Probably not for
- A buyer wanting a community with defined shared amenities or a homeowners' association-run recreational package.
- Someone seeking a uniform, recently built streetscape rather than a mix of decades-old and newer construction.
- A buyer who wants a large pool of comparable listings to shop from, given the limited total inventory here.

The Chateaux Sur Mer Unrec buying strategy.
If we were buying in Chateaux Sur Mer Unrec today, this is the order of operations we would run for our clients.
Underwrite the condition first. Price the roof, HVAC, and systems honestly before judging any list price; condition swings value here more than square footage alone.
Match the home to real comps. Recent sales of similar condition and lot, not the asking price, tell you what a home is worth.
Move deliberately, not desperately. Neither side has a decisive edge, so a well-prepared, fairly-priced offer wins without overpaying.
Line up financing and inspection early. A pre-approval and an inspection plan let you act fast and negotiate from evidence.
Keep an agent in your corner. The listing agent works for the seller; we represent you and prepare a hand-built valuation before any offer in Chateaux Sur Mer Unrec.
A Mix of Eras, Not a Cookie-Cutter Street
The year-built range of 1965 to 2021 is wide enough that no two homes here tell the same story. A median year built of 1978 means older construction is well represented, but the presence of homes built as recently as 2021 shows this is an area where teardown-and-rebuild or major renovation activity has happened alongside long-held original homes.
Median living space of 5,806.5 square feet is substantial, and combined with only 56 homes in the entire inventory, this points to a community of larger, lower-density properties rather than compact or clustered housing. With no listed community amenities, whatever recreational or lifestyle features a buyer wants will need to come from the lot itself — waterfront access, private pool, or similar — not a shared clubhouse or association package.
The location and the amenities are priced into every listing in Chateaux Sur Mer Unrec. The deal is won or lost on condition, the comps, and the renovation math.
