In Siena, a supply gap has emerged where new inventory is arriving faster than homes are selling. Over the rolling six months ending October 31, 2026, 94 new listings were added to the market while only 62 single-family homes closed sales. This imbalance creates a dual-axis trend where supply growth outpaces demand absorption.
ALEX Intelligence analyzed the volume of events to quantify this gap. The difference between the 94 new listings and the 62 closed sales indicates that active inventory is accumulating rather than depleting. While median days on market have improved significantly compared to the prior period, dropping by 44%, the sheer volume of fresh supply prevents a rapid tightening of stock.
The data shows that for every three homes sold, roughly four new listings entered the market during this window. This dynamic suggests a shift toward a more balanced or slightly buyer-favorable environment compared to previous periods where sales outpaced new supply. Buyers now have more options to choose from as the pipeline of available homes remains steady despite the 62 closed transactions.
The sample size for this analysis includes 62 closed sales and 94 new listings, providing a robust view of the current market flow in Siena.
