The property is currently operating as a successful short-term rental, plus the vacation rental license was recently renewed so inspection should be easy, allowing a new owner to continue renting quickly. For buyers looking for a personal getaway, the layout is also ideal as a family vacation property, offering two separate living spaces that allow families or groups to stay close together while still having privacy. New owners can immediately obtain Cabana Club membership, which provides private beach access, pool, and hot tub, and is a major driver for vacation rental bookings in the area. The property is also walkable to restaurants and ocean-view bars. The duplex was fully remodeled in 2021, including new plumbing, flooring, AC system, and interior and exterior paint. Additional updates through 2024-2026 include impact windows and doors, updated ductwork, roof improvements, new drywall in one unit, new washer and dryer, grills, and water heaters, making the property well-maintained and move-in or rental ready. A large outdoor seating area and yard provide space for guests or family to gather, making it especially attractive for groups renting or using both sides of the duplex. Fully furnished and turnkey for immediate use or continued rental income.
