Welcome to 19851 Sienna Lane, a beautifully renovated home in the highly sought-after Yorba Linda Knolls Estates, where over $200,000 in thoughtful upgrades come together with a layout designed for real family living. From the moment you walk in, soaring vaulted ceilings, abundant natural light, and an open, flowing floor plan create a sense of space that feels both elevated and inviting. With five bedrooms and four bathrooms, this home offers the flexibility today's families need, whether it's space for growing kids, multi-generational living, or a dedicated home office. The heart of the home is a fully remodeled kitchen featuring custom cabinetry with built-in storage solutions, quartz backsplash, stainless steel appliances, and seamless connection to the living and dining areas, while a dedicated bar area with sink and storage adds an extra layer of functionality and style that is rarely found at this price point. Nearly every surface has been updated, including new dual-pane windows, luxury vinyl plank flooring throughout, fresh interior and exterior paint, recessed and LED lighting, remote-controlled ceiling fans, custom mirrors, and beautifully remodeled bathrooms with high-end finishes, and this is not a flip as every upgrade was selected with long-term quality and livability in mind. Step outside to a spacious, private backyard designed for both relaxation and entertaining, featuring new sod, low-maintenance landscaping, automated irrigation and lighting, and a semi-covered patio area, with ample space to add a pool or create your ideal outdoor retreat. The home is also equipped with security cameras, an electronic door lock, and thoughtful touches like a finished garage with LED lighting and built-in storage. Located within walking distance to Fairmont Elementary, Bernardo Yorba Middle School, and Yorba Linda High School, all part of the award-winning Placentia Yorba Linda Unified School District, this home offers an ideal setting for families looking to secure both a home and access to top-tier education. Homes with this level of renovation, size, and school access rarely come available in this neighborhood, making this a rare opportunity to move into a truly turnkey home in one of Yorba Linda's most desirable communities.
