Overview

Beautifully remodeled income-producing duplex! This single-story property is move-in ready, with one unit leased to reliable tenants and the other side vacant so you can move in or rent it out. Perfectly positioned just 1.5 miles from Texas State University and 2 miles from the vibrant energy of The Square in downtown San Marcos. Both 2BD/1BA units have been thoughtfully updated with stylish, matching interiors that truly set them apart in the rental market with higher rents. The open-concept living and kitchen areas feel bright and expansive thanks to vaulted ceilings, recessed lighting, and striking stone fireplaces that add warmth and character. Durable wood-look laminate flooring runs throughout, paired with tile in the bathrooms for easy upkeep. Each kitchen is outfitted with modern flair—quartz counters, stainless steel appliances, slide-in gas ranges with designer vent hoods, bar-style seating at the peninsula, and ample storage. All bedrooms include walk-in closets, while the bathrooms feature updated finishes like quartz countertops and showers with stylish designer tile to the ceiling with niche. Each unit has its own laundry setup off the kitchen and a small, private fenced yard with a patio—perfect for enjoying the outdoors. Ideally located right on the university shuttle route and across from a neighborhood grocery. With quick access to I-35, you’re just 30 minutes from Austin and an hour from San Antonio, right in the heart of the Central Texas corridor. A smart investment in a sought-after location—book your showing today!
