All San Marcos market figures and ALEX agents

San Marcos median closed prices rose 9.1% month-over-month to $342,500 across 50 sales in September, yet the market is moving slower than both the prior month and last year. The median days on market climbed 15.6% to 74 days compared to 64 days in August, and rose 2.8% from 72 days a year ago. This divergence between rising prices and longer selling times suggests buyers are negotiating more time while still paying higher averages. When compared to its neighbors, San Marcos median price of $342,500 trails the broader region at $407,250 and Hays County at $372,495. However, San Marcos homes sell for less per square foot at $183, compared to $204 in the region and $185 in Hays County. The local market also shows a lower close-to-list ratio of 0.906 versus 0.941 in the region, indicating sellers are accepting offers further below original list prices than their neighbors do. Inventory levels remain tight with only 6.09 months of supply available today based on September closing rates. While new construction accounted for nearly half of closed sales (23 of 50), the overall living area size increased slightly to 1,926 square feet, up 3.6% from August. These figures highlight a market where price growth is outpacing volume, and local buyers are facing stiffer competition on price but more time to decide than in previous months. Want a closer look?
