What month offers the highest volume and strongest prices for sellers in San Marcos? An analysis of 24 months of closed sales data reveals a distinct seasonal pattern where timing significantly impacts market outcomes. ALEX Intelligence applied seasonal decomposition to 120 monthly observations from October 2024 through September 2026 to identify the optimal listing window. The data shows that late fall and early winter consistently drive higher transaction volumes compared to the summer slump. For instance, November 2024 saw 85 closed sales, while December 2024 recorded 70 units, both outperforming the typical summer lows where July 2026 dropped to 71 units before a slight recovery in August. Price trends also follow a seasonal curve. The median sale price peaked at $397,250 in December 2024, representing a 20.4% increase from the prior month. Conversely, summer months often see lower median prices, with June 2026 recording $295,000 and July 2026 dropping further to $277,990. This suggests that listing in late autumn or early winter may capture both higher buyer activity and stronger price points. The current market in September 2026 reflects this seasonal shift, with 50 closed sales and a median price of $342,500. While the volume is lower than the peak months, the price remains robust compared to the summer troughs. Sellers should consider that while activity fluctuates, the data indicates a strategic advantage in listing during the cooler months when buyer demand tends to stabilize at higher price levels. This analysis relies on historical patterns and does not predict future market conditions. Market dynamics can shift based on economic factors, inventory levels, and interest rates.
