About This Home
Vacant tract in the high-growth NE San Marcos corridor offering strong SH21 visibility and access. Proximity to San Marcos Regional Airport and surrounding development momentum supports commercial, light industrial, or mixed-use development potential. Survey on file. Water and Electricity available with no portion of the Property in the FEMA 100-year floodplain.
At $1.75 million, TBD SH 21 puts 3.838 acres on one of the most watched growth corridors in San Marcos, with frontage that is hard to ignore and a price that works out to about $456,000 per acre. In San Marcos, TBD SH 21 stands out because water and electricity are available, a survey is already on file, and no part of the property falls within the FEMA 100-year floodplain.
This is not a house with a fixed floor plan or a dated build to work around. It is Land - Multiple Lots (Adjacent) in San Marcos, TX 78666, Hays County, and that matters because flexibility is the value driver here. There are no bedroom, bathroom, or square footage figures because this is raw land, and there is no year built because there is no existing residence. What you are buying instead is position, access, and visibility along SH 21 in a corridor where growth has been moving steadily outward.
The location tells the story. State Highway 21 is a key east-west route for San Marcos traffic and regional movement, and San Marcos Regional Airport is one of the clearest nearby landmarks shaping this pocket of the market. That airport proximity, combined with highway exposure, puts the site in range for buyers thinking about commercial, light industrial, flex, or mixed-use potential. In a market where many tracts come with utility questions, floodplain issues, or unclear boundaries, this property starts from a cleaner baseline.
For buyers evaluating the area through a school lens, the property is served by SanMarcosCONSISD, with Mendez Elementary, Goodnight Middle School, and San Marcos High School in the assigned path. Even for land buyers focused on future use rather than immediate occupancy, those campus assignments help define where the property sits within the broader San Marcos framework. The address is in a part of the city that connects to established public infrastructure while still benefiting from room to grow.
Days on market is just 5, which fits what we are seeing when clean acreage hits the market in strategic locations. When land offers SH 21 exposure, utility availability, and airport-area relevance in northeast San Marcos, buyers tend to look closely. TBD SH 21 is the kind of tract that can make more sense over time, because the value here is tied to what this corridor is becoming, not just what it is today.
