How to pay property taxes on a foreclosed home

I recently purchased a home at auction that has overdue property taxes.? This is in California.? What is the procedure to pay off the taxes and how much time do I have to do so?

Just go down to the county tax collectors office to pay. In many counties you can even do it online.
If you plan to flip, and don’t mind paying the interest you might just wait until you resell and let the escrow company take care of it.
Property taxes can remain delinquent for 5 years before the county has the right to take the property to tax sale, which would wip your interest in the property out completely.
