Welcome to 6 New Castle Street, an impressive ocean block home in South Rehoboth, just steps away from the beach, boardwalk, and Rehoboth Avenue. This property offers a total of 8 bedrooms and 7 bathrooms across the primary home and a separate apartment above a two-car garage. Featuring unique design elements no longer allowed under current building codes. This historic property has been fully restored to the charm and architectural integrity to reflect its original 1928 construction. Over the past two decades, the primary home and garage apartment have undergone a complete renovation with new vintage fixtures and modern elements while preserving its historic character. The first floor of the main house boasts a large wraparound sunroom, a spacious eat-in kitchen with granite countertops and updated appliances, pantry, an expansive dining room, and five inviting common areas, including a porch with ocean views. Upstairs, you'll find three well-appointed bedrooms, a private deck offering ocean views, and two full bathrooms. The lower level offers four generously sized bedrooms, three full bathrooms, an additional family room and dining area. Original elements like casement windows were preserved where possible, while modern upgrades were carefully integrated. All wiring was replaced with new copper, and all plumbing has been updated. The walls were fully insulated, and the exterior was fully updated with western red cedar siding. The roof was upgraded with durable 50-year CertainTeed Grand Manor shingles, designed to withstand high winds, and the HVAC system was fully updated with three high-efficiency central units, one per floor. The rear garage apartment was completed with an equally meticulous renovation, including the addition of a brand-new central air system in 2024. A key feature of this property is its grandfathered design, which allows for three stories- something no longer permitted in new construction, resulting in 3,800 square feet of living space while preserving the lawn. The property also includes a two-car garage and a total of 7 off-street parking spaces. The oversized lot is 55 feet wide by 100 feet deep, with a shared easement for additional off-street parking. Located just five houses from the beach and a short walk from downtown, this property offers the perfect blend of historical character, modern comfort, and an unbeatable location. At the rear of the property, a 2-car garage includes a 576 square foot, 1-bedroom, 1-bathroom apartment on the second floor with its own living room and kitchen. Exterior highlights include an outdoor shower and seven off-street parking spaces. With a proven strong rental history, this home is a fantastic investment opportunity.
