The Sonoma County housing report for September 2025 tells a story of strength and steady demand as we head into fall. Unlike Healdsburg, which saw a dip in median pricing, the Sonoma County housing market in September posted a notable gain, keeping the area highly competitive for buyers. Let’s break down the latest Sonoma County market trends for September and see what it means for homeowners, buyers, and second-home seekers.
1. Sonoma County Single-Family Homes Overview in September 2025
Here’s what the numbers show this month in Sonoma County:
- Median Sold Price: $1,185,000 – up 24% compared to August
- Months of Inventory: 4.92 – 18% lower than August, showing supply is tightening
- Median Days on Market: 65 – homes are taking about 10% longer to sell
- Active Listings: 121 – down 14.8% from last month as sellers step back
- Median Price per Sq. Ft.: $755 – unchanged from August
What does this mean? The big jump in median price suggests strong demand, especially for larger homes or properties in desirable neighborhoods. Yet, the fact that homes are taking longer to sell indicates buyers are becoming more selective, balancing enthusiasm with caution. With inventory shrinking, sellers still hold leverage, but the pace of sales reflects a more thoughtful market.

2. How did Luxury Below and Over $2M Sales Perform in Sonoma County by September 2025?
The luxury Sonoma County housing market split into two clear patterns this month:
- Homes under $2M: In the last month, the median sold price was around $1.22M, with an average og 68 days in the market. These homes are the sweet spot, with steady activity driven by Bay Area buyers seeking space and value. Properties under $2M continue to sell faster than the market average.
- Homes over $2M: On the other hand, the median sold price is around $2.75M, with sellers converting after an average of 83 days in the market. The higher end of the market is active, but buyers are negotiating more aggressively. Homes are sitting longer, which reflects why only 6 homes over $2M were sold during August, the same luxury cooling seen across the country.
Overall, Sonoma County’s under-$2M market is leading activity, while the over-$2M tier is steady but slower, echoing broader luxury trends in wine country.
3. What Caused the Year-Over-Year Price Drops in 2025?
Even though Sonoma County’s median price jumped this month, the year-over-year numbers are still lower compared to 2024. Why?
- Higher interest rates: Many buyers remain priced out or hesitant.
- Luxury slowdown: Fewer ultra-high-end closings weigh on median prices over the year.
- Seasonality: Summer demand has cooled, and September is historically a transition month before the winter lull.
- Economic caution: Broader uncertainty has shifted buyer focus toward properties with strong value rather than aspirational purchases.

4. Is It Better to Invest in a Second Home in Healdsburg or Sonoma County?
Both Sonoma County and Healdsburg offer unique benefits, and September’s data helps highlight the differences:
- Healdsburg (September 2025): Median sold price of $975K, down 24% from last month, with a higher price per square foot at $864. Homes are selling faster, but overall demand has cooled, especially for estates above $2M.
- Sonoma County (September 2025): Median sold price of $1.18M, up 24% from last month, with steady $755 per square foot. Homes are taking slightly longer to sell, but the area shows stronger upward momentum.
Which is better for a second home?
Healdsburg is Ideal for exclusivity and long-term appreciation, especially while prices are temporarily lower.
On the other hand, Sonoma County is Attractive for buyers who want more options and larger homes at competitive prices, with strong current demand.
For retirees or those planning, Sonoma County also offers a range of lifestyle-focused options, such as 55+ communities in Sonoma County, which remain a popular choice in today’s market.
Sonoma County Housing Report for September Shows a Better Market for Buyers
The Sonoma County housing report for September 2025 shows a resilient market with rising prices and tightening inventory. With the median sold price up 24% and supply dropping to just under five months, sellers are in a stronger position than earlier this year.
- For Sellers: Conditions lean in your favor. Homes under $2M are moving steadily, and limited inventory gives you leverage if your property is well-priced. Listing this fall could allow you to capture buyers while the momentum is still strong.
- For Buyers: The market is competitive, especially in the under-$2M range, but slower sales in the luxury tier above $2M create room for negotiation. If you’re considering a second home, patience and strategy may help you secure a better deal, particularly at the higher end.
September 2025 in Sonoma County goes for sellers, but luxury buyers still have opportunities in the $2M+ market.
