Coconino County tax sales, Arizona

Verified

Coconino County sells online through RealAuction, with bidding opening in January and all bids closing on the second Tuesday of February, per the county's Tax Lien Packet. The county is unusually transparent about list costs: the internet auction list on CD or hard copy costs $179 plus $15 postage, and the over the counter list costs $62 plus $15 postage. After the auction, leftover liens are sold over the counter from March through December, and the Treasurer posts the current over the counter list on the Tax Liens page. No deposit amount is stated in the packet read, so the deposit is marked unverified.

Bidding and the certificate	Bids compete on the interest rate, down from the 16 percent maximum in ARS 42-18053 under ARS 42-18114. The packet states a processing fee of $12.00 per parcel, per year purchased for the first time (the packet text words the figure as eleven dollar next to the printed $12.00; the printed figure is $12.00), plus the $10 certificate fee under ARS 42-18118. All sales are final.
Redemption	Liens are redeemed through the Treasurer's office; the holder receives a redemption check for the face amount plus the awarded interest rate. Subsequent taxes may be paid on or after June 1 and must be paid by December 31 each year; unpaid subsequent taxes go to the next tax lien auction. Foreclosure is judicial, and on judgment the Treasurer issues a treasurer's deed for a $50.00 fee per parcel.

Research Coconino County parcels before you bid

A sale list gives you the parcels, the date, and the opening terms. It does not give you the owner, the value, or the rest of the picture: liens, foreclosure status, and parcel history. PropertyRadar is the data platform for that layer. It carries owner records, assessed and market values, foreclosure and tax data, and property history for parcels across Coconino County, searchable by address, owner, or county, including parcels that never reach a sale list.

How Arizona tax lien sales work

Unpaid taxes become a lien, and the lien is what sells. Property taxes in Arizona are a lien on the property, and when they stay unpaid the county treasurer prepares the delinquent list (by December 31 under ARS 42-18106), advertises it, and sells the tax lien at the annual sale under Title 42, Chapter 18. What the buyer receives is a certificate of purchase: a lien position against the property, not the property, not a deed, and no right to enter or use it.
The sale runs every February, mostly online. The treasurer of each county holds the annual sale in February. Most Arizona counties now sell through an online vendor the treasurer names on its tax lien sale page; registration and a funded account come before bidding, and each county sets its own registration deadline and deposit rule on top of the statute.
Bidding is the interest rate, and it goes down. Buyers bid the annual interest rate the lien will earn, starting at the 16 percent per annum maximum in ARS 42-18053 and bidding down under ARS 42-18114; the lowest rate wins. The winner pays the treasurer the full amount of delinquent taxes, interest, penalties and fees for the parcel on the day of sale. Competition, not the county, sets the rate a lien actually carries.
Redemption is the normal exit, and it runs through the treasurer. The owner, or another party in interest, may redeem at any time before a court enters judgment foreclosing the lien, by paying the treasurer the certificate amount plus interest at the bid rate, plus any subsequent taxes the holder paid and the statutory fees. The treasurer then pays the holder. Most certificates are redeemed; the interest, not the property, is the usual return.
The deed is a court case that cannot start for 3 years. If the lien is still unredeemed 3 years after the sale, the certificate holder may bring a foreclosure action in superior court under ARS 42-18201. Only a final judgment in that action bars the owner's right to redeem and directs the treasurer to issue a treasurer's deed. Liens nobody buys at the sale are struck off to the state, and the state held liens can later be bought by assignment from the treasurer.

How bidding works in Coconino County

Register at coconino.arizonataxsale.com before bidding or buying over the counter; the bidder number assigned is kept each year for Coconino County.

The rate is the price. A lien bid at 16 percent and redeemed in year two is a different asset from the same lien bid at 4 percent and redeemed in month three. Arizona returns are set in the bid room, before any property question is reached, so model the rate and the likely redemption window first.
The certificate is not the property. No possession, no rents, no right to enter, and no deed for at least 3 years, and then only through a court foreclosure. Buyers who need the property itself should be reading the deed state pages, not this one.

Terms: what a bid actually costs

Deposit, Coconino County	No deposit amount is stated in the Tax Lien Packet read, and none is claimed here.
Payment, Coconino County	Payment for tax lien purchases at the internet auction must be made via ACH, per the Tax Lien Packet, and all sales are final, with no refund once the sale is completed. Over the counter, the county accepts cash in person, checks, money orders and cashier's checks, and cards in person or online through GovPros with a 1.99 percent convenience fee.
What is sold	A certificate of purchase: a lien on the property for the delinquent taxes, penalties, interest and fees. Not the property, not a deed, and no right of possession. A deed exists only at the end of a foreclosure action, years later, if the owner never redeems.
The bid	An annual interest rate, bid down from the statutory maximum of 16 percent. The lowest rate wins the lien. The buyer pays the full certificate amount at the sale and earns the bid rate on the amount while the lien is outstanding.
Redemption	At any time before a foreclosure judgment, through the county treasurer, by paying the certificate amount plus interest at the bid rate, subsequent taxes the holder paid, and statutory fees. The state frame is Title 42, Chapter 18; the county page carries the treasurer's own redemption instructions.
Foreclosure	Available to the certificate holder once the lien has been outstanding 3 years from the sale date, by action in superior court under ARS 42-18201, and not later than 10 years after the last day of the month in which the lien was acquired. Judgment bars redemption and directs the treasurer to issue a treasurer's deed. Before that judgment, the holder owns a claim, not a property.
Lien life	A certificate does not last forever. Under ARS 42-18127, if the lien is not redeemed and no foreclosure action is commenced within 10 years after the last day of the month in which the certificate was acquired, the certificate expires and the lien is void. The treasurer must notify the holder before the deadline, but the deadline runs whether the holder acts or not.
Costs on top of the certificate amount	The sale day payment covers the delinquent taxes, accrued interest, penalties and fees in the certificate amount. A holder who later pays subsequent delinquent taxes on the parcel adds them to the lien position under ARS 42-18121, at the certificate rate; a foreclosure, if it comes, carries court and notice costs the redemption math must also cover.

Unsold liens: over the counter, March to December

Leftover liens become available for over the counter purchase from March through December, with the current list linked from the Treasurer's Tax Liens page (the November 2026 list). Liens that draw no bid are assigned to the state under ARS 42-18113 and are sold by assignment under ARS 42-18122.

Before you bid

Know the redemption window before the rate. Interest accrues at the bid rate from the sale, and the owner can cut it off at any time by redeeming. A lien priced for a 3 year hold that redeems in 90 days pays a quarter of the model; run the short case first.
Read the treasurer's current terms, not a recap. Vendors, registration deadlines and deposit rules change between sales, and county pages are rewritten each season. Re-read them on the treasurer's page before funding a deposit.
Subsequent taxes are part of the position. A holder can pay later delinquent taxes on the parcel and add them to the lien. Budget for carrying the position, not just buying it.
