Market figures by town

What does a 7.2% jump in median price mean for Southwest Austin buyers and sellers in September? The data shows that while the market cooled slightly with fewer transactions, the value of homes sold increased significantly compared to last year. ALEX Intelligence analyzed 128 closed sales in September 2026 to summarize the month's performance. The median close price reached $636,300, up from $575,000 in August and $593,500 a year earlier. This price gain occurred alongside a 14.1% drop in sales volume compared to the previous month, though activity remained higher than the same time last year when only 128 homes sold. Homes took longer to sell on average, with median days on market rising to 32 days from 30 days in August, yet this remains 38.5% faster than the 52 days seen in September 2025. The share of homes selling below original list price held steady at 78.1%, while the close-to-original list ratio improved slightly to 95.2%. New construction accounted for 12 of the 128 closings, and the median living area grew to 2,420 square feet. With 490 active listings and a months of inventory reading of 2.79, the market remains competitive but is shifting toward balance. The data suggests that while demand softened in terms of volume, buyer willingness to pay higher prices for larger homes drove the median value up.
