Yavapai County, AZ

Yavapai County's next tax lien auction is February 9, 2027, held online through RealAuction at yavapai.arizonataxsale.com; the previous one was February 10, 2026. The treasurer's investor FAQ describes how it runs: bidding opens around mid-January and continues until the sale date, the certificates are split into batches of about 500, and the first batch closes at 9:00 a.m. MST, with one closing every hour after that until the last at 4:00 p.m. Bidders register on the auction site — one registration covers every Arizona auction RealAuction runs — and there's no participation fee. A deposit of the greater of $25 or 10% of the certificates you hope to win must be in place by the first Monday in February, a week before the sale, and the last account used for a deposit is auto-debited for the balance the day after the auction; failing to pay forfeits the certificates and the deposit and ends future bidding privileges. A $10 processing fee applies per parcel and tax year (A.R.S. § 42-18153).

Bidders enter a proxy bid for the lowest interest rate they'll accept, from 16% down to 0% in 1% steps, and each certificate goes to the lowest rate, with ties broken at random. Yavapai's published results show how hard investors bid. At the February 10, 2026 sale, 2,151 parcels were offered, 1,813 sold (84.28%) with a face value of $1,634,149.53, 693 certificates went at 0% and only 176 at the full 16%, and the average rate was 4.05%. A year earlier, 1,554 of 1,915 sold, 728 at 0%, at an average of 4.07%. Interest starts on the first day of the month after purchase, and the certificates are electronic. If a lien isn't redeemed, the holder can start a judicial foreclosure three years from the date the taxes first went to sale — the county recommends an attorney — and certificates that don't sell are offered at the county-held tax certificate sale from March to mid-December.
