Don't miss it! Walnut Valley School District! Kick off the holidays in this 3-bedroom townhouse in the fantastic Cross Keys community within the city of Diamond Bar. Step in from the covered front porch to find a great floorplan with hardwood floors, a fireplace and huge windows that let in a ton of natural light. Your open-concept kitchen includes stainless steel appliances (with a professional range), granite countertops, a modern apron sink and a peninsula with bar-top seating overlooking the dining area & living room. Around the corner, the huge family room can serve double duty as a home office or remote-learning spot, too. Both the family room and the adjacent living room offer sliders out to your private, low-maintenance back patio. There’s room to store equipment, create planting beds along the fence and entertain guests in the shade of the growing bougainvillea. Head upstairs to find all of the bedrooms. The master suite includes a huge closet and an ensuite with a dual-sink vanity, a soaking tub and a separate custom-tiled, glass-door shower. The other two guest rooms share the updated hallway bathroom. There’s built-in storage in the bright hallway as well. Back downstairs, you've never seen a garage like this! The unique vaulted ceilings offer you more wall & overhead storage space than you could ever need. Plus, there’s plenty of room for a big laundry area, your cars, sports equipment and toys. Cross Keys residents enjoy amenities like a pool, a clubhouse, tennis courts, picnic areas and landscaped walkways. This quiet community is nestled between the 60&57 Fwys, with views of the mountains in the distance. Of course, you’ll be just minutes from shopping & dining options in every direction, with top-tier schools, parks and golfing close by, too.

No weekly rateNo published rate within 7 days of this date.ZIP averages use publicly displayable closed sales from our licensed MLS feed, matched to the same ZIP and exact property type. Months with fewer than 3 sales are omitted; the current month is incomplete. Lines connect available monthly observations across gaps and do not represent measured prices in missing months. These averages are not adjusted for size, condition, or location within the ZIP, and are not an appraisal. Feed coverage may not include every sale. All available shows the available home and ZIP history, with mortgage rates over the same dates.
Mortgage benchmark: Freddie Mac Primary Mortgage Market Survey®. © Freddie Mac. Weekly national 30-year fixed rates, not APRs or a loan quote. Actual terms vary. Methodology changed in November 2022. The chart does not establish that interest-rate changes caused a home’s price changes.
Lines connect recorded asking and sale prices. They are visual guides, not estimates of the home’s value between those dates.
No earlier records were returned by our current sources. This does not mean the home has never sold.
