September 2026 Market Update
(Based on MLS Activity from August 1, 2026 – September 1, 2026)
Real estate activity across Mendocino, Lake, and Sonoma Counties remained active throughout the latest reporting period, although the numbers show noticeable changes in pricing, sales volume, and marketing times from one county to another.
Buyer demand continues to be present, but buyers remain attentive to price, condition, property presentation, and overall value. Homes that are positioned competitively from the beginning continue to have a stronger opportunity to attract early interest, while properties requiring longer market exposure may face greater negotiation.
The latest MLS numbers also highlight how differently each of the three Northern California markets is performing. While activity increased in Mendocino and Lake Counties, Sonoma County recorded slightly fewer closed transactions than during the previous reporting period.
Below is a breakdown of how each county performed during the reporting period.
Mendocino County
During the reporting period, 64 homes closed in Mendocino County.
Median Sale Price: $529,500
Average Sale Price: $572,599
Average Home Size: 1,588 sq ft
Median Days on Market: 59 days
Price Range:
Highest Sale: $1,610,000
Lowest Sale: $75,000
What This Means:
Mendocino County experienced an increase in closed sales during the latest reporting period, rising from 46 sales in the previous period to 64 sales.
At the same time, the median sale price moved from $567,500 to $529,500, showing that the mix of homes selling during the month shifted toward somewhat lower price points.
Marketing time improved slightly. The median days on market decreased from 68 days to 59 days, suggesting that properly positioned homes were generally reaching buyers somewhat faster than during the previous month.
Approximately half of the homes that closed sold within their first 60 days on the market, demonstrating that buyers are still responding to properties that enter the market at a price consistent with current expectations.
However, properties remaining available for extended periods continue to face greater competition. This reinforces the importance of sellers establishing a realistic pricing strategy early rather than relying on later price adjustments to generate activity.
For buyers, the range in marketing times continues to create opportunities, particularly among properties that have experienced longer market exposure and where sellers may have greater flexibility during negotiations.
Lake County
During the reporting period, 90 homes closed in Lake County.
Median Sale Price: $299,000
Average Sale Price: $335,542
Average Home Size: 1,473 sq ft
Median Days on Market: 70 days
Price Range:
Highest Sale: $2,500,000
Lowest Sale: $85,000
What This Means:
Lake County continued to provide some of the more affordable homeownership opportunities among the three counties, with a median sale price of $299,000 during the reporting period.
Sales activity increased from 72 closed homes in the previous period to 90 homes, showing stronger transaction volume during the month.
At the same time, the median sale price declined from $329,750 to $299,000, while the median days on market increased from 49 days to 70 days.
This combination suggests that buyers remain active in Lake County but are taking more time to evaluate available properties and pricing before making purchasing decisions.
The average marketing time was 115 days, considerably higher than the 70-day median. This indicates that while many properties are selling within a reasonable timeframe, a portion of the market continues to experience significantly longer exposure.
For sellers, entering the market at a competitive price remains especially important. Homes that align closely with current buyer expectations are generally better positioned to generate interest, while properties remaining on the market longer may face greater negotiation or require pricing adjustments.
For buyers, Lake County continues to offer a broad range of price points, and longer market times on certain properties may create additional negotiating opportunities.
Sonoma County
During the reporting period, 381 homes closed in Sonoma County.
Median Sale Price: $775,000
Average Sale Price: $1,034,150
Average Home Size: 1,781 sq ft
Median Days on Market: 40 days
Price Range:
Highest Sale: $38,500,000
Lowest Sale: $210,000
What This Means:
Sonoma County continued to record the greatest number of closed residential sales among the three counties, with 381 homes closing during the reporting period.
The median sale price came in at $775,000, compared with $817,500 during the previous reporting period. The average sale price remained above $1 million at $1,034,150, reflecting Sonoma County's broad range of transactions, including higher-end and luxury properties.
The $38.5 million highest sale during this reporting period also demonstrates how luxury transactions can influence Sonoma County's overall average sale price.
Approximately 38% of closed homes sold within their first 30 days, while roughly 67% sold within 60 days.
The median marketing time increased slightly from 37 days to 40 days, but Sonoma County continued to have the shortest median market time of the three counties.
Homes selling within the first 30 days achieved particularly strong results relative to their original asking prices, reinforcing the advantage that properly priced and well-presented properties can have when they first enter the market.
Properties remaining available beyond 60 to 90 days are more likely to encounter increased competition and may require adjustments in price, presentation, or negotiation strategy to generate stronger buyer interest.
For sellers, realistic pricing and strong marketing remain important from the beginning. For buyers, homes with longer market exposure may provide additional opportunities for negotiation.
Regional Takeaway
Across Mendocino, Lake, and Sonoma Counties:
The latest MLS numbers show an active but increasingly price-conscious Northern California housing market, with meaningful differences between the three counties.
Sonoma County recorded the highest sales volume with 381 closed homes, followed by Lake County with 90 sales and Mendocino County with 64 sales.
Compared with the previous reporting period, Mendocino and Lake Counties both experienced increases in closed sales, while Sonoma County experienced a modest decrease in transaction volume.
Marketing times also varied considerably. Sonoma County remained the fastest-moving market with a median of 40 days, followed by Mendocino County at 59 days and Lake County at 70 days.
Median sale prices further illustrate the differences between the three markets. Sonoma County led at $775,000, followed by Mendocino County at $529,500, while Lake County remained the most affordable of the three at $299,000.
One of the clearest trends in this month's numbers is that median sale prices declined in all three counties compared with the previous reporting period. This does not necessarily mean every individual home's value declined; the mix, location, condition, and price range of the properties that happened to close during each period can significantly influence countywide statistics.
For sellers, the current numbers continue to emphasize the importance of preparation, accurate pricing, and strong marketing from the beginning. Buyers have choices and are carefully evaluating value, making it increasingly important for a property to stand out when it first enters the market.
For buyers, differences in pricing and marketing times across the three counties continue to create opportunities. Properties with longer market exposure may provide additional negotiating flexibility, while newly listed and well-positioned homes can still attract competition.
The Northern California market remains active, but increasingly selective. Understanding the conditions within each individual county — and developing the right pricing or purchasing strategy based on current local data — can make a significant difference in today's market.
