Time on Market Insights
The 381 homes sold during this period were divided as follows:
0–30 Days: 147 homes — 38% of closed sales
31–60 Days: 108 homes — 28%
61–90 Days: 55 homes — 14%
91–120 Days: 34 homes — 8%
120+ Days: 37 homes — 9%
A total of 255 homes out of 381 sold within 60 days or less, showing that well-priced and well-prepared homes are still moving at a solid pace in Sonoma County.
Homes that sold within the first 30 days achieved approximately 102.45% of their original asking price, meaning many sold at or above asking. In comparison, homes that remained on the market for more than 120 days averaged approximately 88.13% of their original asking price.
This is an important sign for sellers: the longer a property stays on the market, the greater the likelihood of price reductions or negotiating leverage shifting toward buyers.
Market Snapshot Takeaway
Sonoma County continues to show a strong and active real estate market, with a $775,000 median sale price, 40-day median market time, and homes selling at approximately 94% of original asking price overall.
The market still rewards homes that are priced well and presented strongly from the beginning. Properties that hit the market in good condition and aligned with current comparable sales may have a better chance of selling quickly and closer to — or even above — asking price.
For buyers, there may still be opportunities among listings that have been on the market longer, particularly where pricing has softened or seller motivation has increased.
For sellers, the numbers reinforce the importance of strategic pricing, strong presentation, and effective marketing in today’s Sonoma County housing market.
