Eighteen homes hit the market in San Marcos between October 24 and October 30, 2026, bringing fresh inventory to a city with 394 active listings. The median list price for these new arrivals was $271,000, representing a median of $200 per square foot across an average living area of 1,761 square feet.
Six of the 18 new listings were newly constructed homes, accounting for roughly one-third of this week's supply. These fresh entries now make up about 4.6% of all homes currently for sale in San Marcos. This influx adds to the existing stock without yet altering the overall months of inventory, which sits at nearly six months based on recent sales pace.
ALEX Intelligence analyzed the composition of this new supply to highlight the immediate shift in available housing types. The data reflects a steady stream of entry-level and mid-range properties entering the market during this seven-day window. While individual addresses are not listed here, these figures represent the total volume of homes that became available for purchase and remained active through the end of the week.
This snapshot captures only the homes that were newly listed and still on the market as of October 30. It excludes properties that sold or withdrew during the same period, focusing strictly on the new supply entering the San Marcos market this week.
