San Marcos, TX 78666 (Hays County)
About this property
Hidden beneath a canopy of mature trees, 121 Merrywood offers 2.7 private acres just minutes from the heart of San Marcos, pairing the seclusion of a Hill Country property with the convenience of being close to everything. Set far back from the street along a secluded drive, the home was designed around its surroundings. Soaring mid-century ceilings and walls of architectural windows bring the outdoors in, while a dual-sided wood-burning fireplace connects two expansive living spaces and gives the home a character rarely found in newer construction. Thoughtful renovations have preserved that character while opening the kitchen and dining areas and adding quartz countertops, beautifully updated bathrooms, wood-look tile throughout, and a newer HVAC system. The privacy carries outside with an expansive backyard, large covered patio, and plenty of room to gather, play, or simply enjoy the surrounding acreage and native wildlife. Yet some of the best parts of San Marcos are only minutes away. Hike the 12+ miles of trails at Purgatory Creek, spend summer afternoons in the spring-fed San Marcos River, explore Spring Lake, or head Downtown for dinner without giving up the space and seclusion that make the property so special. For buyers who want more land without moving further out, 121 Merrywood is a rare opportunity to have both. A complimentary 2/1 interest rate buydown for qualified buyers makes the value even stronger.
