Welcome to 1317 Holly Leaf Way, a rare single-story opportunity tucked away on a quiet private cul-de-sac in one of Diamond Bar's most sought-after neighborhoods, known for its top-rated schools and offered for the first time in 34 years. Lovingly maintained by the same owners for over three decades, this home blends comfort, functionality, and pride of ownership throughout. The open-concept layout offers abundant natural light, spacious living areas, and a distinctive sunken conversation area centered around the fireplace, adding warmth and character to the heart of the home. The flexible fourth bedroom is ideal for a home office, guest room, or additional living space. Thoughtful upgrades have already been completed, including a new roof, updated HVAC system, upgraded electrical panel, dual-pane windows, and an EV charging outlet in the garage, providing modern convenience and energy efficiency while still offering the opportunity to personalize the interior to your own style. The private backyard offers a flat, usable outdoor space with a concrete patio and surrounding privacy walls, ideal for relaxing, entertaining, or creating your own outdoor retreat. Ideally located within the highly acclaimed Walnut Valley Unified School District and within walking distance to Chaparral Middle School, the home is also just minutes from parks, shopping, dining, and convenient freeway access. Combining a peaceful neighborhood setting with everyday convenience, this is a special opportunity in a location where homes are rarely available. See the video walk-through and welcome home!!!
