San Marcos sits right on the I-35 corridor between Austin and San Antonio, and that geography shapes almost everything about living here. The city grew up around the spring-fed San Marcos River, one of the oldest continuously inhabited sites in the Americas, and that deep sense of place still runs through the culture. Texas State University anchors the local economy and gives the city a steady pulse year-round, drawing researchers, educators, and students who settle into neighborhoods that spread well beyond the campus edge.
From the walkable blocks surrounding the Hays County Courthouse Square to the quieter garden-style communities near Wonder World Drive and Purgatory Creek, San Marcos offers real neighborhood variety across its 40 square miles. Renters will find a broad mix of options, including loft-style apartments downtown, apartment communities near the river corridor, and roomier townhome-style rentals toward the city's outer edges. The housing market leans accessible compared to neighboring Austin, making it a practical landing spot for anyone wanting proximity to a major metro without the price tag to match.

The GreatSchools Rating helps parents compare schools within a state based on a variety of school quality indicators and provides a helpful picture of how effectively each school serves all of its students. Ratings are on a scale of 1 (below average) to 10 (above average) and can include test scores, college readiness, academic progress, advanced courses, equity, discipline and attendance data. We also advise parents to visit schools, consider other information on school performance and programs, and consider family needs as part of the school selection process.
