The home is equipped with two independent HVAC systems for upstairs and downstairs, providing enhanced comfort and energy efficiency year-round. No HOA. Ideally located near top-rated schools and just minutes from Bishop Ranch, Central Park, Iron Horse Trail, City Center, Trader Joe’s, Whole Foods, Target, and dining.
