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.
