When property taxes in San Diego County go unpaid, the parcel becomes tax-defaulted. After the statutory waiting period, the county tax collector can sell it at public auction — and the minimum bid is tied to the back taxes owed, not the property’s market value. That gap is the opportunity, and the research is the work.
