In 2023, single-family home inventory followed fairly typical seasonal trends, but at a significantly depressed level, while condo inventory has been in decline since May 2022. Low inventory and fewer new listings have slowed the market considerably. Typically, inventory in San Francisco has two peaks, one in May and one in September, and then declines through December or January, but the lack of new listings prevented meaningful inventory growth. New listings have been exceptionally low, so the little inventory growth throughout 2023 was driven by fewer sales. In November and December 2023, new listings dropped significantly without a proportional drop in sales, causing inventory to fall to an all-time low in December, which further highlights how undersupplied the market has been over the past year. This year, inventory looks to have already seen its first peak in March, which is likely an early sign that inventory will remain tight in 2024.
We were hopeful that inventory and new listings would increase after new listings rose 134% month over month in January 2024. However, new listings have yet to grow at the pace needed to bring a significant increase in inventory. The number of new listings coming to market is a significant predictor of sales, and the substantial increase in new listings in January led to a 68% increase in sales in February. In April, new listings fell 6% month over month, and sales declined 1% in May. The demand in San Francisco is there, but supply — especially new supply — isn’t coming to the market.
Months of Supply Inventory in May 2024 indicated a sellers’ market for single-family homes
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 has been volatile, moving between a buyers’ and sellers’ market throughout the year. From January to May, MSI declined significantly, indicating that single-family homes shifted from balanced to favoring sellers, and condos moved from favoring buyers to balanced.
