In September, sales fell, while new listings surged, nearly doubling month over month, which is actually normal for this time of year. In San Francisco, a significant amount of new listings tend to hit the market in January and September in any given year. Compared to this time last year, new listings are even and inventory is down 10%. Year over year, sales are up 1% for single-family homes, but are down 13% for condos. San Francisco is somewhat unique in that mortgage rates really have brought prices down, so the typical supply-and-demand dynamics don’t really present as well in terms of price in recent history. Single-family home prices peaked at $2.05 million in April 2022 as mortgage rates were rising rapidly; $2 million homes are simply far more affordable with a 4-5% mortgage than a 6-7% mortgage. Because of the relatively high prices of homes in San Francisco, prices had to come down to keep buyers in the market.
Total inventory has trended lower essentially since 2010, but active listings fell precipitously from October 2020 to December 2021, as sales outpaced new listings, before stabilizing to a degree from January 2022 to the present at a depressed level. 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 didn’t resemble the typical seasonal inventory 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 September 2024 indicated a sellers’ market for single-family homes and a buyers’ 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). The San Francisco housing market tends to favor sellers, which is reflected in its low MSI, especially for single-family homes. MSI has been below three months since October 2023 for single-family homes. From May to August, MSI declined meaningfully. In September, however, MSI jumped significantly higher as new listings spiked. Recently, condo MSI indicated a buyers’ market in September, while single-family home MSI still implied a sellers’ market.
