How does rental income work on a Folly Beach two-family or three-family?

Rental income on a Folly Beach two-family or three-family depends on achievable rent for each unit, occupancy consistency, and whether short-term rental is even allowed on that specific parcel under the town's current rules. Carrying costs like flood insurance run higher on the island than inland, which affects net income more than on a comparable mainland property.
