When determining whether a market is a buyers’ market or a sellers’ market, we look to 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 lower than three months of MSI is considered a seller’s market, whereas markets with more than three months of MSI are considered buyers’ markets.
Despite the fact that we’ve seen the North Bay become a buyer’s market over the course of the past few months, we’re currently seeing the trend reverse, as inventories decline. With 3 months of active inventory, Marin has become a balanced market, while Solano, Sonoma, and Napa Counties trend downward, with 3.3, 3.9, and 7.6 months' worth of single-family home inventory on the market, respectively. Likewise, the condo market is entirely a buyer’s market, with 4 months of inventory on the market in Marin County, 4.3 months in Sonoma County, 5.2 months in Solano County, and 7.5 months in Napa County.
