Which school zone is driving the most home sales in San Marcos? The data shows that Hernandez Elementary attendance zone led activity with 20 closed sales in September, followed by Dezavala with 9 sales. ALEX Intelligence ranked these zones strictly by sales volume and median price to identify where market activity is concentrated. This analysis uses a sample of 50 closed transactions across the city to ensure statistical reliability. The Hernandez zone not only had the highest transaction count but also commanded the highest median sale price at $440,875. Dezavala Elementary followed with 9 sales and a median price of $224,999. Crockett Elementary recorded 6 closed sales with a median of $350,249, while Rodriguez (San Marcos ISD) also saw 6 transactions at a median of $374,050. These figures reflect buyer demand patterns rather than school quality ratings. The remaining zones in the city had fewer than five closed sales in this period and do not meet the minimum threshold for inclusion in this ranking. Buyers looking for high-activity neighborhoods may find the Hernandez zone offers the most liquidity, while those seeking lower entry points might consider the Dezavala area. All figures represent actual closed transactions from September 2026. The sample size of 50 sales provides a robust view of current market behavior across these specific school boundaries.
