Rarely do you find a downtown home that offers this much flexibility. Just minutes from Downtown San Antonio, The Pearl, Lower Broadway, the River Walk, museums, award-winning restaurants, the San Antonio Zoo, and countless local shops, entertainment, and nightlife. The detached 1-bedroom, 1-bath casita is the true standout, offering its own private driveway and entrance off Sandmeyer, plus a secluded outdoor patio that creates exceptional privacy from the main home. Whether you're looking to offset your mortgage with rental income, accommodate multigenerational living, host long-term guests, or create the ultimate work-from-home space, the possibilities are endless while allowing both living spaces to maintain their own sense of privacy. Inside the main home, you'll be welcomed by a charming front porch, a durable metal roof, and an inviting open-concept living space with wood-look tile flooring throughout the main level. The updated kitchen features quartz countertops, freshly painted cabinetry, new hardware, gas cooking, and recently replaced stainless appliances. Tucked away on the main level, the light-filled primary suite offers abundant natural light, a spacious walk-in closet, and a private ensuite bath with marble tile flooring and a clean, contemporary design. Recessed lighting throughout enhances the home's bright, modern feel. Upstairs, two secondary bedrooms share a full bath, creating a comfortable and functional layout for family, guests, or roommates. Recent 2026 improvements include interior and exterior paint, recently replaced kitchen appliances, new carpet in the upstairs bedrooms, and a new HVAC blower motor, making this home truly move-in ready. Whether you're searching for a primary residence with income-producing potential, a home that offers space for extended family, or simply the convenience of downtown living with a detached private guest house, 1227 Mason delivers a rare combination of charm, flexibility, and location that's hard to find.
