Siena Market vs. Williamson County and Region Benchmarks

How does a master-planned community like Siena compare to its broader county and regional neighbors? In the rolling six months ending September 30, 2026, Siena median closed prices reached $400,000 across 65 sales. This figure sits just below the Williamson County median of $390,000 and slightly under the Unlock MLS region median of $407,250. The most striking difference lies in market velocity. Homes in Siena sold in a median of 26 days on market. By contrast, the wider region required 56 days and Williamson County took 55 days to close a sale. This indicates that Siena buyers and sellers are moving significantly faster than the average transaction in the surrounding area. Price per square foot tells a similar story of efficiency. Siena listings closed at $175 per square foot, which is lower than the region's $204 and the county's $191. However, the speed of sale suggests strong demand relative to inventory. The market also showed resilience in negotiation; 81.5% of Siena sales closed below original list price, a rate comparable to the regional average of 83.5%. ALEX Intelligence compared these metrics against peer data to highlight where Siena stands as a distinct market segment. While the median home size in Siena grew to 2,344 square feet, larger than the regional average of 2,026 square feet, the faster turnover suggests buyers are prioritizing location and community amenities over raw square footage comparisons. The data confirms that while prices are competitive, the pace of commerce in Siena outpaces the broader Austin area significantly. Want a closer look?
