Median prices hold steady, with Napa as the outlier

Across much of the North Bay, median prices remained stable in July.

• Single-family homes: Up 0.85% in Solano and 3.43% in Marin; down 0.06% in Sonoma and 14.94% in Napa.

Inventory takes a sharp dive

Unlike other Bay Area markets, the North Bay saw steep inventory declines.

• Single-family inventory: 21.98% lower month-over-month, down 12.24% year-over-year.
  
  

• Condos: 17.60% lower month-over-month, down 8.17% year-over-year.
  
  

• Only 850 new single-family listings in July, a 29.28% drop year-over-year — levels we typically don’t see until the holiday season.
  
  

Homes are sitting longer despite fewer choices

Even with low supply, listings aren’t moving quickly. On average, homes spent 20–30% longer on market than last year (7–10 additional days).

• Condos in Marin: 109.68% longer on market.
  
  

• Condos in Napa: 284.21% longer on market.
  
  

• Napa single-family homes were the exception, selling in the same timeframe as last year.
  
  

Competition is heating up as inventory shrinks

Measured by MSI:

• Marin County: 2.3 months → seller’s market.
  
  

• Solano County: 3 months → balanced market.
  
  

• Sonoma County: 3.5 months → buyer’s market.
  
  

• Napa County: 6.8 months → strong buyer’s market.
