Home values stay strong while condos fluctuate

Single-family home prices continue to show steady growth across much of the North Bay. Year over year, prices increased 1.29% in Sonoma, 2.47% in Marin, and 4.17% in Solano, while Napa saw an 8.67% decline.

Condo prices remain more volatile, posting large swings: up 6.98% in Sonoma, 20.07% in Marin, and 29.76% in Napa, while Solano dropped 11.43% year over year.

These trends highlight how local inventory shifts continue to influence values county by county.

Inventory returns to more typical levels

After surging earlier in the year, inventory in the North Bay is finally stabilizing. Active single-family listings are down 0.73% year over year, while condos are up just 2.75%.

This cooling of supply suggests the North Bay market is regaining balance as we move into fall.

Market time remains elevated despite fewer listings

Even with declining inventory, homes are still taking longer to sell than last year. Single-family homes are spending 27–28% more time on market in Sonoma, Solano, and Napa Counties. Marin County is the exception, with listings selling slightly faster—averaging 29 days, down 6.45% year over year.

Marin shifts to balance as other counties stay buyer-friendly

The North Bay is gradually transitioning from a buyer’s market toward balance. Marin County now sits at 3 months of supply, indicating an even playing field. Solano, Sonoma, and Napa Counties remain buyer-leaning, with 3.3, 3.9, and 7.6 months of supply, respectively.

Condos across all counties are still buyer’s markets, with supply ranging from 4 to 7.5 months, giving buyers more negotiating power as we head into the final quarter of the year.

Bottom Line:

The North Bay market is gradually finding its balance. Single-family homes continue to show healthy appreciation, while condo prices remain more variable across counties. Inventory has begun to stabilize after a mid-year buildup, but homes are still spending more time on the market, reflecting a more deliberate pace among buyers. Marin County stands out as the most balanced area, while nearby counties remain buyer-friendly. As we move deeper into the fall season, this region offers a mix of opportunities: sellers benefit from improving demand, while buyers can still find leverage in select areas.
