The Dunes Sanibel Island is a community of 236 homes in Sanibel, Lee County, built between 1974 and 2020 (median 1984), with a median living area of about 4,594 square feet. 54% of parcels are homesteaded, the owner-occupancy proxy in the Florida DOR assessment roll (2025 roll, public records).

The Dunes is a low-turnover pocket of larger-format homes built mostly in the early 1980s, with construction spanning from 1974 up through 2023 for the newer or rebuilt properties, set within Sanibel's broader Lee County market.

At 350 homes, this is a small, defined inventory pool, and the mix skews toward larger houses with a median year built of 1983 — meaning most buyers are evaluating homes at or approaching the four-decade mark, alongside a handful of newer or rebuilt properties from the 1974–2023 range. That age spread matters more here than in a typical subdivision: condition, updates, and storm-related rebuilding history will separate comparable-looking listings more than square footage or lot alone.

A homestead share just over half (50.8%) indicates the ownership base is roughly split between full-time occupancy and non-homestead use, which is consistent with an island market that draws both primary residents and second-home or investment buyers. No community amenities are identified from current MLS listings, so any pool, dock, or club access tied to a specific property should be verified individually rather than assumed as a neighborhood-wide feature.

With only 350 homes and a median 116.5 days on market, pricing and negotiating in The Dunes requires reading each listing's specific condition and build history rather than leaning on a thin, slow-turning comp set — the kind of judgment call we make daily in this exact price band.

Listings in this community report association dues of about $20 per month ($240 a year) — the median AssociationFee across 40 MLS records, normalised to a monthly figure; most are billed annually. Dues change with budgets and can differ by section or product type; confirm the current figure with the association before you offer. Source: MLS listing records, 2026-10.
