About This Home
Location, Location, Location, commercial business tenants. Surrounded by development of San Marcos along IH35 Frontage Rd, corner lot, high traffic; seller finance possible.
At $4.90 million, 1700 S Interstate 35 Fwy S puts 1.11 acres of mixed-use commercial frontage directly on the Interstate 35 corridor in San Marcos, one of the strongest visibility plays in Hays County. In San Marcos, this commercial sale sits in a part of San Marcos, TX 78666 where traffic counts, frontage access, and surrounding development matter more than marketing language ever will.
The value story here starts with location. A corner position along the IH-35 frontage road gives this site exposure to daily north-south movement between Austin and San Antonio, while keeping local access close to key San Marcos routes like Wonder World Drive and Hopkins Street. For owners, investors, or users looking at mixed-use commercial property in San Marcos, that combination supports tenant visibility, easier wayfinding, and long-term land value tied to one of the region's most important highways. Seller financing is reportedly possible, which may widen the pool of viable business strategies.
The property was built in 1959, which gives buyers a clear baseline for due diligence, renovation planning, or repositioning. The lot size is 1.11 acres, large enough to matter on this stretch of frontage where assembled land and corner access can shape future use. Square footage is not listed, so price per square foot is not available from the current data. Bed and bath counts are also not applicable here, since this is a Commercial Sale - Mixed Use asset rather than a residential listing. School district and campus information are not provided in the source data.
From a geographic standpoint, the address benefits from being near the commercial spine of San Marcos with practical connections to downtown San Marcos, Texas State University, and the San Marcos River corridor. The site also sits within reach of major local demand drivers tied to student traffic, commuter flow, service businesses, and regional travel along Interstate 35. That matters in a market where frontage sites are judged by access, surrounding rooftops, redevelopment pressure, and how easily a customer or tenant can see the property from the road.
For buyers asking what it is like to own or operate at 1700 S Interstate 35 Fwy S, the answer is straightforward: this is a high-exposure mixed-use commercial position in San Marcos with land, frontage, and flexibility in a corridor that continues to attract growth. As San Marcos expands along IH-35, sites like this tend to stay relevant because visibility and location remain hard assets that can support both present income and future upside.
