What's Behind the San Mateo County Numbers
A pre-foreclosure in San Mateo County starts with a recorded Notice of Default: the owner has roughly three months to reinstate before the lender can record a Notice of Trustee Sale and set a public auction at least 21 days out. The 35 properties in the auction column are already at that final stage.
On each property, Properant links the foreclosure filing to the parcel's full picture: who owns it and where they actually live, every open loan and its recorded amount, liens against the property, the past-due amount on the defaulted loan, the auction date, city, and opening bid where published — and an AI distress score that weighs all of it, so a statewide list becomes a call sheet ordered by who needs out most.
Bank-Owned (REO) & Foreclosed Homes In San Mateo County
San Mateo County currently has 213 foreclosure-acquired properties on record — homes whose last recorded sale was a trustee's deed, identified the day the deed recorded rather than when a listing eventually appears. Most searches for foreclosed homes in San Mateo County are really looking for these two stages: the 35 properties still headed to auction, where anyone can bid, and the bank-owned homes that already reverted to the lender, which reach the market later through agents. The recorded documents show both — including which lender took each property back, and what it was owed.
Working from recordings instead of listings is the edge: a reverted home can sit weeks or months before an asset manager lists it, and during that gap it has no photos, no price, and no competition. The California Bank-Owned Homes (REO) List covers the mechanics statewide; the San Mateo County properties behind this page's count — each with its lender, foreclosure history, and equity — are searchable inside Properant.
Frequently Asked Questions
How many foreclosures are there in San Mateo County, California?
As of October 12, 2026, Properant tracks 126 pre-foreclosure homes in San Mateo County (91 at the notice-of-default stage, 35 already scheduled for foreclosure auction), plus 213 bank-owned homes and 1,996 tax-delinquent properties. San Mateo County ranks #26 of California's 58 counties for active pre-foreclosures. Counts come from documents recorded with the county recorder and update daily.
Where can I find foreclosed homes for sale in San Mateo County?
Foreclosed homes reach the market two ways: at the trustee sale itself (35 auctions are currently scheduled in San Mateo County — public, cash, often postponed at the podium) and afterwards as bank-owned homes (213 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 91 pre-foreclosures that come before either, which is where investors reach owners directly.
Is there a free San Mateo County foreclosure list?
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.
How do foreclosure auctions work in San Mateo County?
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.
Does the San Mateo County clerk publish a foreclosure list?
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.
What other distress signals does Properant track in San Mateo County?
Beyond foreclosures, San Mateo County currently shows 1,996 tax-delinquent properties, 1,049 open involuntary liens, 202 HOA liens, and 52 active lis pendens filings. Properant's AI reads every signal on a property together and scores the distress Hot, Warm, or Cold.
