Maricopa County Tax Lien Auction

Tax-lien timeline
Year 1
January: A lien for taxes is attached to the property even though the amount of taxes due will not be determined until the following fall. The county assessor notifies each property owner of the property's assessed value.
August-September: The county Board of Supervisors approves the property-tax rate, and residents receive their annual property-tax bill.
October: The first half of the property-tax bill is due.
Year 2
April: The second half of the Year 1 property tax is due.
December: The county treasurer compiles a list of all parcels with delinquent property taxes for publication.
Year 3
January: The Treasurer's Office publishes the list in a newspaper and on the Internet.
February: An online auction is held to sell the tax liens to investors. Bidders compete for the best annual interest rate, bidding down from 16 percent in whole-digit increments (1 percent, 2 percent, etc.) Any liens not sold to investors are "struck" to the state but can be purchased later for 16 percent interest.
Year 6
February: A lien investor can seek a judgment for foreclosure of the tax-delinquent parcel in court if the investor still has not been repaid with interest.
Year 13
February: If no foreclosure action has been initiated 10 years after the date of purchase, the lien is extinguished.
