What makes Sullivan's Island different for investment property in 2026?

Sullivan's Island stands apart for investment property in 2026 because of its strict short-term rental limits, limited buildable land, and flood insurance costs that run higher than most inland Lowcountry towns, factors that shape returns more than anything happening in the broader market. Those restrictions also mean fewer comparable sales to price against, so each deal needs individual analysis rather than a general investment formula. Brian Beatty walks investors through those Sullivan's Island specifics before they commit to a purchase.
