Southwest Austin Home Sizes Are Growing in September

Are homes getting bigger in Southwest Austin? The data says yes. In September 2026, the median living area for closed sales reached 2,420 square feet, up from 2,149 square feet in August and 2,402 square feet a year ago. This shift toward larger floor plans occurred across 128 transactions, representing a 12.6% increase compared to the prior month and a 0.7% rise year-over-year. ALEX Intelligence analyzed rolling trends in home size to identify this pattern. The data shows that buyers are increasingly settling on properties with more square footage, even as the median price climbed to $636,300. This represents a 10.7% jump from August and a 7.2% increase compared to September 2025. The trend suggests a changing preference in the market where size is becoming a priority alongside location. While the median price per square foot dipped slightly by 1.9% from the prior month, the overall footprint of sold homes continues to expand. This growth in living space indicates that new listings and sales are catering to buyers seeking more room without necessarily sacrificing affordability relative to the broader market. The shift is evident across the neighborhood spectrum, with larger homes driving the median upward. As inventory adjusts, the average home size in Southwest Austin appears to be trending higher, reflecting a demand for spacious living environments in this part of Travis County. Want a closer look?
