How do I value a Dewees Island investment property in 2026?

Valuing a Dewees Island investment property means comparing it against the island's very small pool of comparable sales and factoring in the ferry-only access that limits both tenant demand and how quickly a future sale could close. Rental restrictions under the island's covenants also shape what income the property can actually generate. Brian Beatty builds that specific comparison for Dewees Island investors rather than applying a broader Charleston-area rental model.
