How many months of inventory does it take to determine if Siena is a buyer's or seller's market? The answer lies in the ratio of active listings to recent sales. With 36 homes currently for sale and 65 closed sales over the trailing six-month period, the market stands at 3.32 months of inventory.
This figure places Siena firmly in balanced territory. A market is typically considered a seller's market when inventory falls below four months, while anything above six months favors buyers. The current level suggests neither side holds a decisive advantage, though the pace has shifted significantly compared to the prior period.
The supply gap has narrowed as sales activity accelerated. Closed sales doubled from 32 in the previous six-month window to 65 now, while active inventory remained relatively stable. This surge in demand helped drive the median close price up 5.3% to $400,000, even as the median price per square foot dipped 5.4% due to a shift toward larger homes averaging 2,344 square feet.
Days on market also contracted sharply, dropping 67.1% to a median of 26 days compared to the prior period. This speed indicates that well-priced homes are moving quickly despite the balanced overall inventory. Buyers and sellers in Siena should expect a competitive environment where properties priced correctly will attract multiple offers within weeks.
ALEX Intelligence calculates this balance by dividing current active listings by the monthly average of closed sales over the analysis window. The data reflects 65 transactions across the rolling six months ending September 30, 2026.
