Frequently Asked Questions
How many active pre-foreclosures are there in San Mateo County?
Properant tracks 126 active pre-foreclosures in San Mateo County as of October 12, 2026 — ranked #26 of California's 58 counties — counted from recorded county documents with releases and cancellations removed.
Is a San Mateo County pre-foreclosure list better than an auction list?
They serve different strategies. Pre-foreclosure owners — especially at the NOD stage — still control the property and can sell, which is where direct outreach works. The auction subset matters when you plan to bid. This list holds both stages, separately filterable.
Can I download the San Mateo County list?
