A useful market clue

Redwood City reports 13 days of median marketing time, compared with 11 in San Mateo.

Same observation window. Marketing time can describe homes going under contract, a different group from closed sales. It does not establish a discount you can negotiate.

City context helps you choose what to investigate. It does not establish affordability or predict which city will outperform.

What stands out

This is a comparison of published city evidence and investigation questions, not a city ranking or a forecast. Lower citywide prices do not establish undervaluation or affordability.

  1. Redwood City’s median sale price is 9.9% higher than San Mateo’s, using San Mateo as the denominator. Window: 2026-06-01 to 2026-08-31.

    Different homes sell in each city. This does not establish a like-for-like premium, affordability or a negotiating discount.

    Evidence 1Evidence 2
  2. Redwood City reports 13 days of median marketing time, compared with 11 in San Mateo. Window: 2026-06-01 to 2026-08-31.

    Different homes sell in each city. This does not establish a like-for-like premium, affordability or a negotiating discount.

    Evidence 1Evidence 2
  3. San Mateo’s all-homes modeled value changed 46.8% over ten years, compared with 50.7% in Redwood City. Exact period: 2016-07-31 to 2026-07-31.

    All homes, regardless of your selected type. Nominal change excludes ownership costs, rent and financing; past change is not a forecast.

Limits of this brief

  • This is a comparison of published city evidence and investigation questions, not a city ranking or a forecast. Lower citywide prices do not establish undervaluation or affordability.
  • Transaction medians reflect homes sold in the stated window. All-homes history is a separate modeled index, smoothed and seasonally adjusted. Exact shared dates and baselines are required; null means unavailable and zero remains zero.
  • Small or missing sales counts are shown beside the values. The latest published evidence can be older than today's brief; age notices use the actual market period end.
  • Jobs are annual Q2 beginning-of-quarter workplace snapshots, not employed residents, unique workers or an annual average.
  • LODES 8.4 all jobs: one California release, 2020 blocks, 2024 place boundaries; 2012–2023.
  • Completions are self-reported certificates of occupancy or other readiness, all housing types; 2018–2025. They include replacement units and do not measure net additions or actual occupancy.
  • Eight date-conflict city-years are reconciled to original city current-year summaries. Original unfiltered HCD totals remain in reportedUnits; acceptedUnits supplies the chart. San Bruno 2020 and South San Francisco 2024 remain withheld. Audit records retain all positive row IDs and source decisions; no excluded units are reassigned to another year.
  • County jobs cover the entire county. No county completion total is provided; the HCD county jurisdiction covers only unincorporated territory.
  • Current revised data cannot establish what was known historically. No new predictive rule or forecast is implied.
