San Bernardino County Tax Sale Research & Auction Data

San Bernardino County conducts tax deed sales for properties with five or more years of delinquent taxes. As California's largest county by land area—spanning over 20,000 square miles from the Mojave Desert to the San Bernardino Mountains—the county's tax sales feature an unusually diverse mix of properties: vacant desert parcels, mountain cabins, residential lots in growing communities like Victorville and Hesperia, and occasional commercial properties. The county has transitioned to online auctions through Grant Street Group's DeedAuction platform, replacing the previous in-person format. Annual sales typically list 1,500-2,500 parcels, with sell-through rates averaging 45-60% depending on market conditions. The high volume of desert land requires careful due diligence—access, utilities, and zoning restrictions vary dramatically between otherwise similar-looking parcels.
