The Local Lowdown
Quick Take:
Median sale prices were mixed across the North Bay in December, with Napa County single-family homes seeing 7.34% year-over-year growth while Sonoma and Solano Counties experienced slight declines.
Inventory levels have plummeted dramatically, with single-family home inventory down 38.85% and condo inventory down 27.99% on a year-over-year basis.
Despite the inventory crunch, listings are spending considerably more time on the market than they did last year, with single-family homes in Solano County sitting 42.86% longer.

Key takeaway
Sales pace varies by county even amid tightening supply
The holiday season brings a sharp shift toward seller's markets
Market conditions are measured using Months of Supply Inventory (MSI)
California’s historical average is ~3 months of MSI, indicating a balanced market
Below 3 months MSI = seller’s market
Above 3 months MSI = buyer’s market
December marked a strong shift toward seller’s market conditions
Single-family homes
Marin County
0.8 months of supply
–66.67% year-over-year
Sonoma County: 1.5 months of supply
Solano County: 1.8 months of supply
Napa County: 4.0 months of supply (down from buyer’s market conditions earlier in 2025)
Condo market
Sonoma County: 2.2 months of supply
Marin County: 2.0 months of supply
Solano County: 3.5 months of supply
Napa County: 3.7 months of supply
Takeaway
Inventory has tightened significantly across the North Bay
The new year may be an excellent time to list, as buyers compete for fewer available homes
