Market figures by town

Are buyers in Siena choosing larger homes today? The data suggests a clear shift toward more spacious living. Over the rolling six months ending September 30, 2026, the median home size reached 2,344 square feet across 65 closed sales. This represents a 12.8% increase compared to the prior six-month period and a 7.1% rise year-over-year. ALEX Intelligence analyzed the relationship between home age, condition, and size to track these trends. The average living area has grown steadily, moving from 2,078 square feet in the previous six months to the current median. This expansion coincides with a drop in price per square foot, which fell 5.4% compared to the prior period as larger homes entered the market at lower relative rates. The shift indicates that while the median sale price rose 5.3% to $400,000, buyers are securing significantly more interior space for their investment. The median days on market also dropped sharply by 67.1% to 26 days, suggesting these larger homes are moving quickly. As inventory tightens and new listings rise, the trend toward bigger floor plans appears to be a defining characteristic of the current Siena market. Want a closer look?
