About This Home
As of October 2025This beautifully updated single-story home showcases a modern kitchen, hardwood floors throughout, and stylishly renovated bathrooms. The spacious floorplan includes large bedrooms with an expanded primary suite, offering comfort and flexibility. The large primary suite featuring a nook area with built-in shelving, access to the backyard and an en-suite bathroom is ideal for relaxation. Light and bright interiors are enhanced by recessed lighting, while fresh interior and exterior paint add to the home’s move-in ready appeal. A backyard bonus space of approximately 16.5’ x 11’ with electricity provides the perfect setting for a home office, gym, workshop, or game room. Outside, refreshed landscaping enhances the curb appeal, and the desirable court location offers privacy and a peaceful setting. Relax in the private backyard where mature fruit trees—fig, persimmon, apple, lemon and orange—offer both beauty and bounty. Live close to excellent schools as well as shopping, dining and parks.
