San Marcos sits right in the middle of the action — halfway between Austin and San Antonio on I-35, wrapped around the crystal-clear San Marcos River and home to Texas State University. That location and energy make it one of Central Texas’ most dynamic markets, and one of its more affordable: the median sale price is about $315,000 as of mid-2026, essentially flat year over year, with homes averaging around 130 days on the market — plenty of room for buyers to negotiate.
Why buyers choose San Marcos
San Marcos offers big-city access with a college-town feel. Buyers come for the affordability relative to Austin, the river and outdoor lifestyle, the outlet-mall shopping, Texas State University, and quick I-35 commutes in both directions. It draws first-time buyers, investors, families and downsizers alike — including active-adult buyers heading to the popular 55+ community here.
San Marcos neighborhoods & communities
The city has a strong lineup of master-planned communities. Kissing Tree is the well-known 55+ resort-style community, while La Cima, Blanco Vista, Trace, Whisper and Cottonwood Creek offer newer homes, amenities and a range of price points. See current listings on the San Marcos homes for sale page.
What San Marcos homes cost
With a median around $315,000, San Marcos is friendlier to budgets than Austin or the Hill Country. New construction is widely available, often with builder incentives in the current market, and you’ll find everything from starter homes and townhomes to larger family homes in amenity communities. If you’re selling to buy here, begin with a home valuation so you know your numbers.
