About this home
Looking for a home that gives you more than just four walls? This Rancho Tesoro gem is worth a closer look. Now offered with a $70,000 price adjustment, this beautiful home in gated Vientos offers one of the neighborhood’s largest backyards, no neighbors behind, and a versatile floor plan with two primary suites. And then there’s the community. Vientos has the kind of neighborhood feel that’s hard to find—Fourth of July bike parades, Santa’s annual visit, food truck gatherings, and neighbors who genuinely connect. Step outside and the backyard becomes an extension of the home, with a built-in BBQ bar, outdoor refrigerator, two covered patios, fire pit, and plenty of space to entertain, relax, and enjoy the privacy of having no neighbors behind. Inside, the two primary suites offer exceptional flexibility for multigenerational living, guests, or simply creating space for everyone. 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. Need a more space? The finished detached flex space with electricity and windows is ready to become a home office, art studio, gym, or hobby room. * * The motor court setting is another unexpected bonus. * * Tucked toward the end of the motor court and away from through traffic, it offers a peaceful, cul-de-sac-like setting where kids can ride bikes and play. Come see why this one is worth a closer look.
Barham Discovery Community, located between Discovery Street and Barham Drive, is a residential and campus-adjacent San Marcos neighborhood with hillside streetscapes and pocket parks. The neighborhood’s character concentrates around the Discovery Street and Barham Drive junction, where school drop-offs, walkers, and cyclists set a steady daytime rhythm. Housing reads as late-20th-century Southern California—stucco exteriors, tile roofs, and cul-de-sacs that follow the terrain. Nearby, California State University San Marcos adds a collegiate pulse and cultural calendar. Trails and open-space edges shape an outdoors-forward routine, while local coffee and casual dining cluster along nearby San Marcos Boulevard.
