Located in the highly sought-after and award-winning Walnut Valley Unified School District, this spacious 4-bedroom, 2-bathroom Diamond Bar home offers 2,500 SF of living space on a 9,000 SF lot—just one block from Walnut Elementary. A bedroom and full bath on the main level, a cozy brick fireplace in the formal living room, and a permitted 700 SF family room addition provide flexibility and room to grow. The nearly 500 SF enclosed patio extends the living area outdoors, and the backyard features five mature fruit trees—orange, grapefruit, tangerine, and lemon. With most nearby homes offering less square footage, this home stands out as one of the larger options in the neighborhood. Similarly sized remodeled homes have recently sold at significantly higher prices. The home is in great structural condition and has been well cared for—pricing reflects its original cosmetic finishes and the opportunity to add value. Home is being sold as-is.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
