Marin County leads a strong summer rally
June brought impressive gains to much of the North Bay's single-family home market. Marin County stole the show, with the median single-family home selling for $1,825,000, an 8.63% jump compared to June 2025. Sonoma County also performed well, with the median sale price rising 2.94% year-over-year to $875,000, while Solano County gained 2.63% to $585,000. Napa County continued to be the outlier, with the median single-family home selling for $920,000, a 12.38% decline compared to last June. The condo market painted a more challenging picture, with all four posting counties year-over-year declines. Napa County condos fell 28.87%, Marin County dropped 19.16%, Solano County declined 7.69%, and Sonoma County dipped 1.35%.
Sales are booming despite tight inventory
The inventory story in the North Bay remains one of scarcity, but that hasn't stopped buyers from making moves. Single-family home inventory now sits at 2,771 units across the region, down 32.66% compared to June 2025. The condo market has also contracted, with just 397 units available, a 12.75% year-over-year decline. Despite the limited selection, sales activity has emerged. Single-family home sales jumped 11.34% year-over-year, with 1,060 homes closing in June alone. This strong demand in the face of limited supply continues to support prices in the most desirable markets. New listings remain well below last year's pace, down 23.22% for single-family homes and 8.46% for condos, suggesting that inventory constraints will persist into the second half of the year.
Buyers need to move fast in today's market
June brought brisk sales velocity across most of the North Bay's single-family home market. Marin County led the way with a median of just 18 days on market, a 28% improvement compared to last June. Solano County single-family homes also moved faster, selling in 30 days, an 11.76% year-over-year improvement. Sonoma County came in at 32 days, down 3.03% from last year. Napa County was the exception, with the median single-family home spending 45 days on the market, a slight 4.65% increase year-over-year. The condo market was mixed, with Sonoma and Solano Counties seeing significant improvements (down 22.50% and 26.42%, respectively), while Marin County condos are spending nearly twice as long on the market as they were last year.
Summer brings strong seller's market conditions
When determining whether a market is a buyers' market or a sellers' market, we look at the Months of Supply Inventory (MSI) metric. The state of California has historically averaged around three months of MSI, so any area with at or around three months of MSI is considered a balanced market. Any market that has less than three months of MSI is considered a seller's market, whereas markets with more than three months of MSI are considered buyers' markets.
June brought a significant tightening of inventory as we hit the peak of summer selling season. The single-family home market is firmly in seller's territory in three of the four counties. Marin County has just 2 months of supply, down a remarkable 57.45% year-over-year. Solano County sits at 2.8 months (down 26.32%), and Sonoma County has 3.4 months of supply (down 39.29%). Napa County remains a buyer's market at 6.8 months, although this represents a 25.27% improvement compared to last year. The condo market is more balanced across the board, with Marin County at 4.1 months (down 32.79%), Sonoma County at 4.5 months, Solano County at 4.8 months, and Napa County at 6.6 months. Overall, sellers continue to enjoy the upper hand, particularly in the single-family home market, as the summer selling season hits its stride.
