Arizona Sells Liens, Not Deeds: 8,717 of Ours Are Under $1,000

Arizona is a tax lien certificate state. There is no county election, no hybrid track, and no tax deed auction. When property taxes go unpaid, the county treasurer auctions a Certificate of Purchase each February, and the buyer holds a lien that earns interest, not the property. That is the short answer, and it takes one sentence. The useful part takes longer, because the number everyone quotes about Arizona — 16% — is the number you bid away from, not the number you earn.

So which is it, tax lien or tax deed?

A lien, statewide. Arizona is a classic tax-lien-certificate state. Each February counties auction certificates of purchase on delinquent parcels, and investors bid the interest rate down from a 16% maximum. The certificate is a lien that earns interest, not title. The owner may redeem at any time during a 3-year redemption period measured from the sale date.

Title only enters the picture later, and only through a court. After 3 years — and before the certificate expires at 10 years — an unredeemed holder can file a judicial foreclosure in Superior Court to extinguish the right of redemption and obtain a treasurer's deed. An administrative deed is not available, and the action can be contested.

That last paragraph is why people search for "is Arizona a tax deed state" at all. A deed does exist at the end of the road, so the word turns up in Arizona listings and forum posts. But you cannot buy one at the auction. What is for sale in February is a lien.

Three things follow from that, and they are the ones that catch out-of-state bidders:

1. You bid the interest rate down, not the price up. Bidding starts at 16% and descends in 1% increments, with the certificate awarded to the bidder accepting the lowest rate (A.R.S. §42-18053). Competition lowers your return directly.
2. The headline rate is rarely the rate you get. In competitive counties like Maricopa, rates are routinely bid down to 1-5%. The winning bid-down rate is what accrues until redemption.
3. The certificate has an expiry date. It expires 10 years after purchase if no foreclosure action is brought. Buy a lien, sit on it past year ten, and the asset can simply stop existing.

Hold on to the second one. The rest of this page is what a bid-down return looks like when it is applied to the size of lien Arizona actually produces.

How many Arizona properties are actually tax delinquent?

Almost nobody publishes this, so here is ours, read from the live county database on 22 August 2026:

• 12,073 tax-delinquent properties in our Arizona file, every one of them in Cochise County
• 1 of Arizona's 15 counties with priced delinquent records in our data
• $15,518,085.07 owed in total across those records
• $667.75 median lien, against a $1,285.35 average — a gap of not quite two times
• $22.53 on the smallest lien in the file, and $689,713.92 on the largest
• 204 of the records carry a street address; the other 11,869 are identified by parcel number only

A property counts as delinquent here when the county's own delinquent file shows money owed on it. Full county parcel rolls, which list every property including the ones paid up, are excluded. Cochise County's file contains 12,073 records and all 12,073 of them owe money, which is the shape a real delinquent roll has.

One coverage note before any of the numbers below, because it is the difference between an honest Arizona figure and a wrong one. We also hold a large Maricopa County record set, but not one record in it carries a dollar amount owed. A count without an amount cannot be added to a dollar total, and we will not publish one that pretends otherwise. So every figure on this page is a Cochise County figure. There is no statewide Arizona delinquency total here, and the 12,073 above is not an estimate of Arizona — it is a count of the one county we can price.

The liens are small, and that is the whole story

Here is the distribution of what is owed, read straight from the file:

Amount owed	Properties	Share of properties	Share of dollars
Under $1,000	8,717	72.2%	25.8%
$1,000 to $4,999	2,978	24.7%	32.7%
$5,000 to $24,999	348	2.9%	25.8%
$25,000 and up	30	0.2%	15.8%

8,717 of the 12,073 properties, 72.2% of the file, owe less than $1,000. The median is $667.75. That is the typical Arizona lien, and it is worth sitting with, because it collides with the bidding rule described above.

Run the arithmetic on the median. A $667.75 lien bought at the statutory maximum of 16% earns about $106.84 over a full year. The same lien bought at a bid-down 3% earns about $20.03 over a full year. Neither number is a typo, and neither covers a day of travel to a county you do not live in. The return on an Arizona certificate is a percentage of a small number, and the auction is designed to push that percentage down.

The dollars behave very differently from the properties. 30 properties, 0.2% of the file, carry $2,446,692.53 of the $15,518,085.07 owed. Widen that to every lien of $5,000 or more and it is 378 properties — 3.1% of the file — holding 41.5% of the money. If there is a case for working Arizona from a screen rather than by volume, that is where it lives: a few hundred records carry most of the value, and the other eleven thousand seven hundred are rounding.

What this means if you are actually bidding

Put the statute and the file together and Arizona reads as a yield play with a low ceiling and a lot of administration, not as a way to acquire property:

• You are underwriting a redemption, not a house. The owner has 3 years from the sale date to redeem (A.R.S. §42-18152), and most certificates simply redeem. Realistic returns are the bid-down rate, not the parcel.
• Getting a deed is a lawsuit, not a form. Converting a certificate requires a judicial foreclosure in Superior Court after year 3. There is no administrative deed in Arizona, and the action can be contested. Price that cost against a median lien of $667.75 before you plan on it.
• Two clocks run at once. Redemption opens the door at year 3; the certificate itself dies at year 10. The window is wide but it is not infinite, and nothing reminds you.
• Small liens are not automatically safe liens. A $22.53 lien and a $689,713.92 lien sit in the same file. The amount owed tells you the size of the debt, not the condition of the parcel or what else is attached to it.

What we actually hold for Arizona

Cochise County, priced, as of 22 August 2026 — 12,073 records, all owing, totalling $15,518,085.07. That is one of Arizona's 15 counties. We do not currently publish priced delinquent data for Pima, Pinal, Yavapai, Mohave, Coconino or the rest, and the Maricopa records we hold carry no amount owed, so they are excluded from every dollar figure above.

The Cochise file is also a parcel file rather than an address file: 11,869 of its 12,073 records identify the property by Assessor's parcel number, and only 204 carry a street address. For a lien buyer that is usually workable, because the treasurer sells by parcel number too. For anyone planning to drive or mail the list, it is the first thing to know about it.

Arizona tax lien questions

Is Arizona a tax lien or tax deed state?

Arizona is a tax lien certificate state, statewide. County treasurers auction Certificates of Purchase each February, and the buyer holds a lien that earns interest, not the property. A treasurer's deed exists only at the end of a judicial foreclosure in Superior Court, brought after the 3-year redemption period. You cannot buy a deed at an Arizona tax sale.

What interest rate does an Arizona tax lien earn?

The statutory maximum is 16% per annum, bid down at auction. The winning bid-down rate is what accrues — in competitive counties like Maricopa, that is often just 1-5%. The 16% figure is a ceiling, not an expected return.

Do you bid the interest rate down in Arizona?

Yes. Bidding starts at 16% and descends in 1% increments, and the certificate is awarded to the bidder accepting the lowest rate (A.R.S. §42-18053). Competition lowers your return rather than raising your cost, which is the opposite of how a premium-bid deed state behaves.

When is the Arizona tax lien sale?

Annually in February, as statutorily mandated. Bidding windows open in mid-January on the online platform and close on the February sale date. RealAuction hosts many county sales.

How long before you can foreclose on an Arizona tax lien?

3 years from the sale date. After that, and before the certificate expires at 10 years, the holder may file a judicial foreclosure in Superior Court to obtain a treasurer's deed. The owner may redeem at any time during that 3-year window (A.R.S. §42-18152).

Do you get the property when you buy an Arizona tax lien?

No. You get a Certificate of Purchase — a lien earning interest. Title comes only later, through a Superior Court foreclosure action, and most certificates redeem before that. An administrative deed is not available in Arizona.

Can an Arizona tax certificate expire?

Yes. The certificate expires 10 years after purchase if no foreclosure action is brought. Track the purchase date, because nothing in the process prompts you before the certificate lapses.

How many tax delinquent properties are there in Arizona?

12,073 priced tax-delinquent properties in our Arizona file as of 22 August 2026, all of them in Cochise County, carrying $15,518,085.07 owed. The median lien is $667.75 and the average is $1,285.35. A property counts as delinquent when the county's own delinquent file shows money owed on it; full parcel rolls are excluded. This is a Cochise County figure, not a statewide Arizona estimate.

Which Arizona counties does LienSuite cover?

Cochise County only for priced delinquent records, as of 22 August 2026. Arizona has 15 counties, and we do not yet publish priced delinquent files for Maricopa, Pima, Pinal, Yavapai, Mohave, Coconino or the rest. Every Arizona figure on this page is a Cochise County figure and has not been extrapolated to the state.

Where these numbers come from

Every property count, median, average and dollar figure on this page was read from LienSuite's live county database on 22 August 2026, aggregated from 206 county sources and refreshed on an ongoing basis. The underlying Cochise County file was last refreshed on 21 August 2026. "Tax delinquent" means the county's own delinquent file shows money owed on the property; we exclude full parcel rolls, which is why this count is in the thousands rather than the hundreds of thousands. All 12,073 Cochise County records owe money.

The $15,518,085.07 total is the sum of the amount owed across all 12,073 records, not an extrapolation; the $1,285.35 average is that sum divided by that count, and $667.75 is the true median rather than the average wearing a different name. The four owed bands sum to 12,073 records, to 100% of properties and to 100% of dollars, and the $2,446,692.53 concentration figure is the $25,000-and-up band read from the same query. Of the 12,073 records, 204 carry a street address and 11,869 identify the property by parcel number only.

We publish no statewide Arizona delinquency total, and no dollar figure that includes Maricopa County. The Maricopa records in our database carry no amount owed, so they cannot be summed, averaged or added to a count of priced liens; leaving them out is deliberate and it is why the coverage figure above says one county rather than two. We also publish no "years delinquent" breakdown for Cochise: the county's file carries a single uniform value in that field rather than a real spread, so a chart of it would show a shape the data does not actually have. Figures move as counties publish new rolls; the dates above are the read date and the file date.
