Foster City Tax Delinquency — Questions
How many tax-delinquent properties are there in Foster City, California?
As of October 12, 2026, Properant tracks 63 tax-delinquent properties in Foster City — owners who are behind on their property taxes according to the San Mateo County tax roll. Foster City ranks #684 among California cities for tax delinquency. The roll is read daily, so properties that pay up drop off.
What happens when property taxes go unpaid in California?
Unpaid property taxes become "tax-defaulted" after the fiscal year closes. The county adds penalties every month, and after five years of default on a home the tax collector can sell the property at a public tax-deed auction. The owner can redeem it at any point before the sale by paying what is owed. Five years is a long runway, which is why tax delinquency is an early distress signal rather than a deadline.
Are these tax lien properties for sale in Foster City?
Not lien certificates — California is a tax-deed state. There is no tax lien sale and no tax lien auction in San Mateo County, because the county never sells liens to investors. After five years of default it can sell the property itself at a tax deed sale, and the buyer receives a recorded deed rather than a lien position. Most people searching for tax lien properties in Foster City are looking for that sale, and the 63 homes counted here are the pipeline it is drawn from — years earlier, while the owner can still sell or redeem.
Is a tax-delinquent list the same as a foreclosure list?
No. A foreclosure comes from a lender and starts with a notice of default recorded against the loan. Tax delinquency comes from the county and never touches the lender. They often overlap — an owner who has stopped paying the mortgage has usually stopped paying taxes too — and a property carrying both is the strongest distress signal on the board. Foster City currently has 4 homes in pre-foreclosure alongside its 63 tax-delinquent properties.
