$70,000 Price Reduction | Space, Privacy & a Community to Call Home! A $70,000 price reduction makes this special Rancho Tesoro home an opportunity worth discovering! Located in the gated Vientos community of San Marcos, this beautifully upgraded 2018 home offers one of the neighborhood’s largest backyards, no neighbors behind, a flexible two-primary-suite floor plan, and a welcoming community where neighbors become friends. What truly sets Vientos apart is its sense of community. From the festive Fourth of July bike parade and Santa’s neighborhood visit to food truck gatherings, there are plenty of opportunities to connect, make memories, and build lasting friendships. The expansive backyard offers no neighbors behind, and plenty of room to entertain, with a built-in BBQ bar, outdoor refrigerator, two covered patios, and a fire pit. Inside, two primary suites provide flexibility for multigenerational living or extended guests. The downstairs suite features private backyard access, a walk-in closet, and its own stackable washer and dryer. Upstairs, the second primary suite offers two oversized walk-in closets. A finished detached flex space with electricity and windows is ideal for a home office, art studio, or hobby room. Love the motor court setting! Tucked at the end of the motor court, away from through traffic, it offers a more peaceful place for kids to ride bikes and play —a cul-de-sac-like feel that's hard to find. With a spacious, private backyard, a flexible floor plan, and a vibrant community, this is more than a home—it's a place to put down roots and enjoy the best of Rancho Tesoro living.
