A rare opportunity to invest, expand, or create your beachside retreat! This versatile coastal duplex, with no HOA, is just one block from the heart of downtown Leucadia and sits on an expansive 10,000+ sq. ft. lot-offering endless possibilities. Each two-story unit features 2 bedrooms, 1.5 baths, a private 2-car garage, a view deck, and a beautifully landscaped yard with a spa, grassy area, and room for an ADU or pool. Both units have been updated with luxury vinyl plank flooring and well-appointed kitchens, featuring gas ranges, refrigerators, dishwashers, microwaves, granite countertops, and rich wood cabinetry. The southwest-facing backyard is private, flat, and primed for expansion. Whether you choose to live in one unit and rent the other, lease both, or transform the property into a stunning single-family beach retreat, the potential is unmatched. Additional highlights include attached 2-car garages with in-unit laundry and ample on-site parking. With top restaurants, stunning beaches, boutique shopping, farmers' markets, and easy freeway access just minutes away, this is a rare find in one of North County's most coveted coastal neighborhoods.
