Property is moderate renovation needed.
The property is exceptionally well-maintained and move-in ready, but it retains many original features from its 1983 construction. While the kitchen has updated stainless steel appliances and the flooring has been upgraded to wood-look materials, the cabinetry, tile countertops, and bathroom fixtures are stylistically outdated. The presence of popcorn ceilings and older fluorescent light boxes aligns with the 'fair' criteria for a home that is aged but functional and well-kept without a full modern renovation.
The property is situated within the highly acclaimed Walnut Valley Unified School District and is within walking distance to Evergreen Elementary and Diamond Bar High School, a major draw for families.
Featuring a sought-after downstairs bedroom and high ceilings in the formal living areas, the layout is perfectly suited for multi-generational living or a flexible work-from-home environment.
The home has been meticulously maintained and professionally landscaped, offering a true move-in-ready experience with significant pride of ownership evident throughout.

At under 6,000 square feet, the lot size is relatively compact for the area, and the 'peek-a-boo' view may not satisfy buyers looking for more expansive outdoor space or vistas.
