THE HOME, IN THE LISTING AGENT’S WORDS

A closer look.

Welcome to 301 Armstrong, a well-maintained 3-bedroom, 2-bath home offering a little extra breathing room in the heart of San Marcos. With no neighbor directly behind the home and no neighbor on one side, the setting offers an added sense of separation and privacy that can be hard to find this close to town.

Read the full description

Inside, the open floor plan makes great use of the space, creating an easy flow between the living, dining, and kitchen areas—perfect for everyday living or spending time with friends. New flooring was installed throughout the home in August 2025, and the interior has recently been refreshed with new paint, repaired baseboards, recaulked finishes, and new blinds throughout. The primary bedroom features its own private half bath and walk-in closet, while two additional bedrooms offer flexibility for guests, a home office, hobbies, or whatever fits your lifestyle.

One of the home’s standout upgrades is the LifeSource whole-home water filtration system, providing filtered water throughout the house without the hassle of individual filters. The home has clearly been cared for, making it an inviting option for someone looking for a comfortable home that feels fresh and ready to enjoy.

Out back, the privacy-fenced yard creates a comfortable space for morning coffee, pets, outdoor dining, or relaxing at the end of the day. With fewer adjoining homes around the property, the backyard enjoys an added sense of privacy while still being close to everything San Marcos has to offer.

And when you’re ready to head out, you’re just minutes from downtown, Texas State University, the San Marcos River, local restaurants, shopping, and easy access to I-35. 301 Armstrong offers a comfortable home base with added privacy, thoughtful updates, and an easy San Marcos lifestyle.
