Welcome to 3920 San Marcos Place, a rare single-level home tucked at the end of a cul-de-sac on an oversized pie-shaped lot. With 4 bedrooms, 2 bathrooms, 1,920 square feet of living space, and 10,854 square feet of land, this home combines layout, location, and lot size in a way that's difficult to find in today's market. What immediately stands out are the vaulted ceilings that run throughout the kitchen, living room, dining room, family room, and primary suite, creating an open and airy environment that feels significantly larger than its footprint. Large windows flood the home with natural light, while recessed lighting throughout keeps the space bright and inviting. The kitchen has been tastefully updated with brand new cabinetry, countertops, and backsplash, offering a modern aesthetic that complements the home's warm neutral tones. A centrally positioned kitchen island provides additional prep space and serves as a natural gathering point, while a dedicated pantry adds valuable storage and everyday practicality. Both bathrooms have been refreshed with new tile and updated vanities, giving the next homeowner peace of mind with meaningful upgrades already completed. What truly separates this property is the lot. Positioned at the end of the cul-de-sac, the unique pie-shaped configuration creates a massive backyard with depth and width that most track homes simply cannot offer. Whether you're envisioning a pool, outdoor kitchen, expanded entertaining area, or future ADU potential, the canvas is already there. The attached two-car garage offers direct access into the home for everyday convenience. All four bedrooms are located on a single level, making the floor plan ideal for families, downsizers seeking single-story living, or anyone looking to avoid stairs long term. Zoned to the highly regarded Fullerton Union High School District and just minutes from Downtown Brea, Brea Mall, Arovista Park, and the 57 freeway, the location provides connivence and proximity to entertainment and recreational activities. With single-story homes on oversized cul-de-sac lots becoming increasingly difficult to find, 3920 San Marcos Place presents a unique opportunity to secure space, flexibility, and long-term upside all in one. Make sure to check it out before it's too late.
