Months of Supply Inventory (MSI) quantifies the supply/demand relationship by measuring how many months it would take for all current homes listed on the market to sell at the current rate of sales. The long-term average MSI is around three months in California, which indicates a balanced market. An MSI lower than three indicates that there are more buyers than sellers on the market (meaning it’s a sellers’ market), while a higher MSI indicates there are more sellers than buyers (meaning it’s a buyers’ market). The San Francisco market tends to favor sellers, at least for single-family homes, which is reflected in its low MSI. However, we’ve seen over the past 12 months that this isn’t always the case. MSI indicated that single-family homes and condos began the year in a buyers’ market. MSI has declined sharply since January for both single-family homes and condos, indicating that the climate has shifted from a buyers’ market to a sellers’ market for single-family homes and a balanced market for condos. The sharp drop in MSI occurred due to the higher proportion of sales relative to active listings and less time on the market.
