How does a market shift when homes sit longer and prices dip? In Lago Vista, the ALEX Intelligence Market Heat Score for September 2026 reflects a cooling trend. This composite index blends four key signals: median days on market, sale-to-list ratio, inventory levels, and price reductions.
The score reflects a shift in conditions compared to recent months. Median days on market rose to 78 days, up 21.9% from the prior month and down 14.3% from September 2025. Homes sold for 90.5% of their original list price, a 5.3% drop month-over-month but slightly better than the same time last year. With 199 active listings and 12 closings in September, months of inventory stood at 6.71, indicating a shift toward buyer leverage.
ALEX Intelligence calculated this score using equal weights for days on market, price ratio, inventory pressure, and reduction frequency. A score near 50 suggests a balanced market, while lower scores point to softer demand. The data shows that while sales volume remains modest with only 12 closed transactions, the pace of negotiation has slowed significantly.
This analysis is based on 12 closed sales in September 2026 and current inventory counts. It does not predict future prices but reflects the conditions observed during the reporting window. Buyers may find more negotiating room, while sellers should expect longer marketing periods and potential price adjustments to move listings.
