Welcome to this beautifully upgraded, north facing home in the gated Rancho Tesoro community of San Marcos. Located in the desirable Vientos/Terracina neighborhood, this spacious 4-bedroom, 3-bath home offers approximately 2,550 square feet of comfortable and thoughtfully designed living space. Inside, the open concept layout feels bright, welcoming, and private. The main living area flows into a modern kitchen with a large quartz island, white shaker cabinets, a custom tile backsplash, and stainless steel appliances that are included with the home. A full bedroom and bathroom on the first floor provide a convenient option for guests, extended family, or a home office. Upstairs, the spacious loft offers even more flexibility and could easily be used as a playroom, office, media room, or converted into a fifth bedroom.

Two additional bedrooms, a laundry room, and plenty of storage complete the second floor.
