Located in the highly desirable Alta Vista neighborhood, 435 W Summit Ave is a beautifully maintained duplex offering classic charm and income-producing potential just minutes from downtown San Antonio. This unique property features two separate units: a 3-bedroom, 2-bath unit on the ground floor and a 2-bedroom, 1-bath unit upstairs, each with its own private laundry area, making it an ideal setup for owner-occupants, multigenerational living, or savvy investors. Set on a spacious lot, the home offers exceptional functionality with a detached garage featuring two separate stalls, additional storage space, and a large driveway that provides ample parking for both residents and guests. Inside, both units are filled with natural light and showcase a blend of timeless finishes and thoughtful updates, including hardwood and tile flooring, generously sized bedrooms, and well-equipped kitchens that make everyday living comfortable and convenient. In addition to the existing income-producing duplex, the detached garage offers a prime opportunity for conversion into a third unit or casita. With the right vision, this space could add valuable rental income. Positioned in one of San Antonio's most walkable and established neighborhoods, this property offers quick access to The Pearl, San Pedro Springs Park, Trinity University, and the city's top dining and cultural attractions.
