In August, inventory and new listings declined, which is normal for this time of year, while home sales rose. Compared to this time last year, inventory has increased significantly, up 31%. Sales are up 3% for single-family homes, but condo sales declined 4%. Any amount of increasing inventory is good for the Marin market. Inventory still has a long way to go before the market begins to become more balanced. When we take a longer look back and compare the supply of homes in August 2019 (pre-pandemic) to now, active listings have decreased by 43%. With that in mind, it should be no surprise that sales have declined by 35%.
Total inventory has trended lower essentially since 2010, but active listings fell precipitously from September 2020 to December 2021, as sales increased dramatically during that period, before stabilizing from January 2023 to the present at a depressed level — still 21% lower than two years ago. Low inventory and new listings, coupled with high mortgage rates, have led to a substantial drop in sales and a generally slower housing market. Typically, inventory begins to increase in January or February, peaking in July or August before declining once again from the summer months to the winter. In 2023, sales and inventory didn’t resemble the typical seasonal peaks and valleys. It’s looking like 2024 inventory, sales, and new listings will follow historically seasonal patterns, albeit at a depressed level. It’s clear that supply will remain tight until spring 2025 at the earliest.
Months of Supply Inventory in August 2024 indicated a sellers’ market for single-family homes and a balanced market for condos
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). Over the past two years, single-family home MSI has varied between a sellers’ market and a balanced market, while condo MSI has varied between a balanced market and a buyers’ market. Since May 2024, MSI has declined significantly. Currently, MSI indicates that the single-family home market favors sellers, and the condo market is balanced.
