As of August 27, 2026, Properant tracks 158 pre-foreclosure homes in San Mateo County (117 at the notice-of-default stage, 41 already scheduled for foreclosure auction), plus 222 bank-owned homes and 1,996 tax-delinquent properties. San Mateo County ranks #25 of California's 58 counties for active pre-foreclosures. Counts come from documents recorded with the county recorder and update daily.

Foreclosed homes reach the market two ways: at the trustee sale itself (41 auctions are currently scheduled in San Mateo County — public, cash, often postponed at the podium) and afterwards as bank-owned homes (222 on record), which lenders list through agents. Properant shows both stages address by address, with the sale date, opening bid, owner and loan history — and the 117 pre-foreclosures that come before either, which is where investors reach owners directly.

The counts on this page are free and update daily. The address-level list — every pre-foreclosure, auction and bank-owned home in San Mateo County with the owner of record, open loans, liens and an equity estimate — is inside Properant, which starts with a free trial. The underlying filings are public record at the county recorder; Properant links all of them to their properties statewide.

California foreclosures are mostly non-judicial trustee sales: after the notice-of-default period the trustee records a notice of sale with the date, time and place, and the property is sold to the highest cash bidder — the lender's opening bid is typically the debt owed. Each scheduled sale in Properant carries the date, published opening bid, the trustee, and the owner and loan history behind it; postponements are common, so the live date matters.

Not as a list. In California, foreclosure documents — notices of default, notices of trustee sale, trustee's deeds — are recorded with the San Mateo County recorder (in some counties the clerk-recorder), and are searchable there one document at a time by name or document number. No county publishes a running "foreclosure list". Properant reads every recorded filing in San Mateo County daily and turns it into exactly that list, with the property, owner, loans and auction details attached.

Beyond foreclosures, San Mateo County currently shows 1,996 tax-delinquent properties, 657 open involuntary liens, 171 HOA liens, and 49 active lis pendens filings. Properant's AI reads every signal on a property together and scores the distress Hot, Warm, or Cold.
