AFAICT those are the national figures from a National Association of Realtors (NAR) report. I can't find figures for California. EDIT: The closest I could find was an ambiguous stat in a CNN article, https://money.cnn.com/2017/04/27/real_estate/home-prices-sellers-market/index.html https://money.cnn.com/2017/04/27/real_estate/home-prices-sel..., which cites an average of a little over 4 years (2000-20007) that might be for San Jose. However, there's wording that suggests such figures are computed from the tenure of sellers, not across all homeowners, in which case the statistic seem useless (imagine one guy selling every two years and nobody else--that would be a 2-year tenture average but in fact nobody but him is moving). Would nice if the NAR report was freely available.
