Use "Schedule a tour" in the contact panel — pick a couple of times that work and your Sullivan's Island agent confirms the showing, usually the same day.
It's listed as Active as of the last MLS sync (shown below the description). Coastal inventory moves — if it's a fit, tour it sooner rather than later.
Zone maps change and parcels differ — nothing here is an insurance quote or a flood determination. It is the homework that gets you real answers fast; verify anything that matters with your insurer.
