Gorgeous, completely remodeled 4-bedroom home on a cul-de-sac in a highly sought after neighborhood within the enrollment boundaries of Walnut Valley Unified School District. This is NOT an investor flip and it shows! In fact, this home has not been on the market in 44 years. The owners completely renovated the interior with the intention of continuing to live here, but their plans changed. They invested in high-end materials and quality craftsmanship, creating an elegant, contemporary home. The formal living room has vaulted ceilings, luxury vinyl plank flooring and an abundance of natural light. The remodeled kitchen has high-end white cabinetry, quartz counters, and brand-new stainless steel GE appliances, including a French door refrigerator, 5-burner gas range, built-in microwave and a dishwasher. There is a formal dining room adjacent to the kitchen and living room. For informal gatherings, an eating area next to the kitchen flows into a spacious family room with a brick fireplace and a 13’ x 17’ bonus room addition. Fully remodeled half bath downstairs, plus a laundry room with a new GE Smart HQ washer and dryer and direct access to the 3-car garage. There are 4 bedrooms upstairs, including a luxurious 20’ x 14’ primary bedroom with a walk-in closet. The en suite bathroom has dual sinks, a mirrored medicine cabinet with interior lights and touch-controlled exterior lights, a walk-in shower with marble-like porcelain walls, a Delta rainfall shower head and a handheld shower wand. The other 3 bedrooms have mirrored closet doors and city lights views. The hall bath has a bathtub, rainfall shower head, Kohler mirrored medicine cabinet, and a mirror with touch-controlled LED lights. Outside, the huge back yard is primarily concrete with level dirt, but it has many possibilities: there is room to add on to the house, build a deck, add a jacuzzi and pool or sport court, or even build an Accessory Dwelling Unit (ADU). There is a gated RV parking area measuring 12’ x 40'+ on the side of the house. The driveway has additional parking for three cars. Brand new Milgard dual pane windows throughout. New Lennox central air and heat. New PEX plumbing installed throughout in November 2022. Fresh interior paint. The best quality, all new luxury vinyl flooring with 4 ½” baseboards throughout. Recessed lighting throughout. Enjoy the tranquility of this beautifully renovated home on a quiet cul-de-sac in a fantastic Diamond Bar neighborhood.
