400 Ocean is a small, closely held community on St. Simons Island where transaction volume is low enough that a single listing can define the market at any given time. Pricing here tracks unit-level factors more than broad neighborhood trends, given how few sales set the tone.

The math at 400 Ocean is unusual: a median days-on-market of 100 alongside a seller-leaning supply picture. That is not a contradiction so much as a signature of a niche building — when there is only one thing to buy, the right buyer sometimes has to wait for it to surface, and the right price has to be found through negotiation rather than comparison shopping.

No community amenities are identified in current MLS data for this listing set, which is common for smaller buildings where the draw is the address and the ocean proximity itself rather than a packaged amenity list. Anyone evaluating this community should treat the building and unit condition, not a brochure of shared features, as the primary variable driving price per square foot.

In a market with one active listing and a handful of closings a year, pricing a unit correctly or evaluating an offer requires real familiarity with the building's sale history, not a generic St. Simons Island comp set. Momentum tracks these thin, address-specific markets closely so clients are not guessing at value in a building where the next comparable sale might be months away.

Listings in this community report association dues of about $453 per month ($5,436 a year) — the median AssociationFee across 35 MLS records, normalised to a monthly figure; most are billed monthly.
