Market figures by town

In Siena, a near-perfect balance between supply and demand has emerged over the last six months. ALEX Intelligence analyzed 66 new listings against 65 closed sales to reveal a tight equilibrium in the market. This dual-axis comparison shows that for every home sold, roughly one new listing entered the market during the period ending September 30, 2026. The median close price rose 5.3% compared to the prior six-month window, reaching $400,000 across 65 transactions. However, the supply of new homes has kept pace with this activity. The number of new listings (66) matches the volume of closings (65), suggesting that inventory is not accumulating nor depleting rapidly. This balance contrasts with the prior period, where only 32 sales occurred against 46 new listings, indicating a shift toward a more active market. While prices have climbed, the median price per square foot dropped 5.4% to $175, as homes sold averaged 2,344 square feet, up 12.8% from the prior period. The days on market also fell sharply by 67.1%, dropping to a median of 26 days. This combination of rising prices, larger home sizes, and faster sales suggests that while new supply is entering the market, buyer demand remains strong enough to absorb it quickly. The data reflects a stable environment where new inventory is matched by sales volume, preventing a backlog of unsold homes. Buyers and sellers in Siena are operating in a market where the flow of new listings keeps the pipeline full without overwhelming the number of transactions. Want to see this home?
