Depending on the statistic and the source of data, analyses in this report will pertain solely to the Diablo Valley region, to Diablo Valley & Lamorinda, or to Contra Costa County, as delineated on each chart.
The table below compares Q3 statistics across 5 years. Q3, summer, typically sees a slowdown from the more heated selling season of Q2, spring, but the pandemic flipped seasonal market trends upside down.
Median sales prices can rise because of increases in fair market value – i.e. buyers are paying more money for the same home (supply and demand) – and/or because buyers are purchasing larger, more expensive houses, often in more expensive communities. Both dynamics are currently at play, but it is certain that affluent and very affluent buyers have made up a dramatically increasing percentage of the demand in East Bay and Bay Area markets.
Year over year, the average size of houses sold in the Diablo Valley-Lamorinda region increased by 4.3% in Q3.
