November Newsletter – Silicon Valley Local Lowdown

The market is cooling but it’s still not a buyers’ market

Quick Take:

  • Home prices increased dramatically in 2021. From January through September, single-family home prices rose across counties:
    • San Mateo County: +16% 
    • Santa Clara County: +19%
    • Santa Cruz County: +11%
  • Despite historically low inventory, the increase in home sales and speed of sales reflect the high demand in Silicon Valley.
  • Months of Supply Inventory further indicates a sellers’ market.

Note: You can find the charts/graphs for the Local Lowdown at the end of this section.


Home prices moved like stocks in 2021

The growth rates in 2021 are highly unusual and unsustainable; for example, home prices would more than double every five years at a 15% growth rate. After huge single-family home price appreciation in the first half of the year, it made sense that prices declined in the third quarter. During the summer months (July–September), San Mateo County home prices declined 13%, up 16% for the year. During the same time period, Santa Clara home prices experienced a less substantial decline: a drop from 27% in June to 19% in September. Santa Cruz gained 1%, bringing the year-to-date price increase to 11%.

Condo prices are near all-time highs in Silicon Valley. Similar to single-family homes, prices contracted in the third quarter. Although the price appreciation wasn’t as pronounced for condos as it was for single-family homes, the growth rates for condos in 2021 are also unsustainable. 


More supply, no problem

Despite the increase in single-family home inventory in 2021, we’re still at a historic low. August and September are typically the months with the highest inventory every year. In 2021, total inventory didn’t come close to last year’s level and was even further away from pre-pandemic levels. Even though we’re seeing some price correction after the first half of the year, the sustained low inventory will lift prices. Sales in Silicon Valley have been incredibly high, again highlighting demand in the area.


Homes are selling fast — really fast

Homes are selling faster than at any point in the last 15 years. The Days on Market reflects the high demand for homes in Silicon Valley. Buyers must put in competitive offers, which, on average, are 1–5% above the list price of the home. 

Months of Supply Inventory (MSI) quantifies the supply/demand relationship by measuring how many months it would take for all current homes for sale on the market to sell at the current rate of sales. The average MSI is 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). MSIs in Silicon Valley are near all-time lows for single-family homes and condos, indicating a sellers’ market in all markets.
