Market figures by town

How does the Siena market compare to its broader neighbors? In the rolling six months ending September 30, 2026, Siena saw 65 closed sales with a median price of $400,000. This represents a 5.3% increase from the prior six-month period but remains 2.4% below the same window last year. Homes in Siena spent a median of 26 days on market, a significant improvement over the 79 days recorded previously and 29.7% faster than the same period last year. ALEX Intelligence benchmarked these figures against regional and county data to highlight relative performance. While the broader region and Williamson County both reported a median price of $405,000 and $390,000 respectively, Siena's median price per square foot stood at $175, lower than the region's $204 and the county's $191. The speed of sales in Siena also outpaced the regional average of 56 days on market. The data indicates a distinct local dynamic where inventory turnover is faster, yet price appreciation per square foot lags slightly behind the wider area. Buyers in Siena are securing homes at a lower cost per unit of living space compared to the broader Austin region, while sellers benefit from a quicker sales cycle. This divergence suggests that Siena offers a unique value proposition within the competitive landscape of Central Texas real estate. Want to see this home?
