3504 Duval St A great investment opportunity in the heart of central Austin with an array of development options! This pre-inspected duplex features a 2 bed, 1 bath front unit and a 2 bed, 2 bath back unit on a large, approximately 8, 500 sq ft lot with alley access. Stable, below-market rents of $4, 350 per month with long-term tenants in place make this a solid income property with room to grow. The home has a new roof (August 2025), and the main sewer line was replaced in 2009. The SF-3 zoned lot offers real flexibility: add income-producing units at the back of the lot with alley access while keeping the existing structure in place, expand the footprint of the existing home, or completely reimagine the property. See agent for details and a copy of the feasibility study (completed September 2026). The UT bus stop is right outside the front door, and you're close to Central Park, Central Market, the Triangle, Hyde Park, Hancock Golf Course, and many more central Austin hot spots.
