46% of San Marcos apartments are running specials right now.

The belt of purpose-built student housing running northeast from campus along Aquarena Springs Drive and Post Road, and by a wide margin the largest concentration of rental inventory in San Marcos. Almost everything here leases by the bed rather than by the apartment, and that is the single most important thing to know before you compare a price to anywhere else in town. Furnished units, roommate matching and August lease starts are the norm, and so is a shuttle to campus. If you are not a student this is still worth a look in the summer, when operators get realistic about unfilled beds.

The blocks close enough to walk to class, wrapped around the quad and Sewell Park where the San Marcos River comes out of the ground at a steady 72 degrees. Inventory is tight and it turns over on the academic calendar, so the good units are gone by March for an August move. What you pay for is the walk: no parking permit, no shuttle, and the river is the campus swimming hole. Expect noise during the semester and a very quiet summer.

The courthouse square and the streets west of it. Restaurants, live music and the shortest commute in town if you work or study downtown, in a mix of older buildings and newer infill. Rents sit at the higher end for what you get in square footage, and parking gets genuinely tight once the semester starts. Renters pick it for the same reason people pick any downtown: everything is a walk, and the walk is pleasant.

About a mile east of downtown, wedged between the Blanco and the San Marcos rivers and sitting right on I-35. This is where price and location meet: five to ten minutes to the square, immediate highway access for anyone splitting time between Austin and San Antonio, and consistently softer rents than campus or downtown. The neighborhood runs renter-heavy and mixes long-term residents with students. One thing to check before you sign, and it is real here rather than a formality: river-adjacent addresses can fall inside a floodplain, which changes what renter's insurance costs.

South of campus along Wonder World Drive, the cross-town route that lets you skip I-35 entirely. The second largest district in the city and the most mixed: older garden communities, recent construction, and a good share of the market-rate family stock in San Marcos. Ten minutes to campus without living in the student belt, close to the grocery run and the south-side retail, and quieter at 2am than anywhere north of the river. You drive, but you drive on surface streets rather than the interstate.

The far south end of San Marcos where I-35 meets Centerpoint Road, anchored by the Premium Outlets and the retail that grew up around them. The newest apartment construction in the city is here and it is priced like it. You are furthest from campus of anywhere in town, which is exactly the point for renters who work in Austin or San Antonio rather than at the university: the on-ramp is right there and you skip the downtown traffic entirely.

Northwest of campus toward Craddock and the hills, on the quieter side of the city. More established than the student belt and more residential in feel, with a mix of older garden communities and small newer builds on tree-shaded streets. Close enough to campus for a five-minute drive, far enough that the semester does not set the tone of the neighborhood. Purgatory Creek Natural Area and its trail system are the local amenity people actually use.

The newest edge of San Marcos, north along I-35 toward the Blanco River and the Kyle city line. Recent construction on larger sites, built for the Austin commute rather than for the university, with rents to match the build year. This is the direction San Marcos is growing, so expect more of it and expect the drive into town to get busier. For anyone whose work is north, it removes fifteen minutes a day off the front of the commute.
