About this home

Prime South Diamond Bar Fixer with Endless Potential in Award-Winning School District! Brought to market with incredible potential, this spacious two-story home located in a highly desirable South Diamond Bar neighborhood is ready for your creative vision and personal touches. Situated on a generous 0.37-acre lot with no common walls, this floor plan offers 3,073 square feet of comfortable living space featuring 5 bedrooms, 3 bathrooms, and a massive upstairs bonus room. The main level welcomes you with high cathedral ceilings at the entry and living room, a formal dining area, a convenient main-floor bedroom with a full bath, and an open-concept kitchen flowing directly into the family room with a cozy fireplace and French doors. Additional highlights include an attached 3-car garage (featuring a permitted bonus study room conversion space). Step outside to discover a private, sprawling backyard complete with a pool/spa, covered patio, and an elevated hillside path leading up to a gazebo with incredible local views. While the home requires cosmetic updating and TLC throughout, its solid bones, prime location just minutes from top-rated schools (Castle Rock Elementary, South Pointe Middle, and Diamond Bar High), shopping plazas (including H Mart), and easy access to the 57 and 60 freeways make this a rare diamond in the rough. Bring your contractors, designers, and imagination to transform this property into your dream estate!
