How Tax Sales Operate in Arizona
Under Ariz. Rev. Stat. § 42-18101 et seq., delinquent property taxes follow a precise statutory timeline. Understanding the difference between bidding on Tax Lien and purchasing over-the-counter is essential for investors.
Bidding & Auction Process
Auctions are conducted online via RealAuction or in person by the County Treasurer. Winning bidders are required to tender payment via wire transfer, certified check, or ACH within statutory deadlines.
Over-The-Counter Lands (County Held Certificate (OTC))
In Arizona, unsold properties or tax lien certificates become available as County Held Certificate (OTC). Buyers can purchase these parcels directly over-the-counter without attending an open outcry auction.
