108 GM Ln Turnkey investment opportunity in one of Central Texas' fastest-growing markets. Located in a welcoming and well-established community in San Marcos, this extremely well-maintained duplex offers the perfect blend of immediate income potential and long-term upside. Built in 2007, both units feature 3 bedrooms and 2 bathrooms, thoughtfully designed layouts, and hard surface flooring throughout for durability and easy maintenance. Each unit enjoys its own private, fully fenced backyard, creating added appeal for tenants seeking space, privacy, and a more residential feel-an increasingly sought-after feature in today's rental market. From an investment standpoint, this property checks all the boxes. Unit A is currently leased, providing immediate income, while Unit B is vacant, offering flexibility for an owner-occupant, house-hacker, or the ability to lease at current market rates. The location further enhances its value. Just minutes from the San Marcos River, I-35, Downtown San Marcos, and nearby Martindale, residents enjoy quick access to recreation, dining, shopping, and major commuting routes-making this an attractive option for a wide range of tenants. Whether you're an investor looking to expand your portfolio or a buyer seeking a smart way to offset your mortgage, this property presents a rare opportunity to secure a well-kept duplex in a high-demand area. This is more than just a duplex-it's a strategic investment in growth, flexibility, and long-term value.
