How this is measured
Figures summarize asking prices on listings that were active in San Mateo County during the last 180 days, counted once per unit. Craigslist is excluded in this market because its room shares and sublets are posted with whole-apartment bedroom counts, which pushes neighborhood medians far below every other source.
RentReboot removes bedroom groups with fewer than 5 observations from this report. Figures are a point-in-time market summary and can move as listings appear or disappear. Read the rent-data methodology or inspect recent San Mateo County listings.
