La Paz County tax sales, Arizona

Verified

La Paz County is the least documented sale in this Arizona set. The county's own record confirms the sale exists: in the Board of Supervisors minutes of April 28, 2026, Treasurer Leah Castro explained that the Treasurer's office conducts the annual tax lien sale and manages state deeding processes in coordination with other offices. No Treasurer sale page with dates, registration, deposit or payment terms was found on lapaz.gov. Third party guides describe an in person February sale in Parker, most recently on February 26, 2025 at the Board of Supervisors boardroom; none of that is verified from county sources, and it is flagged as unverified wherever it appears on this page.

Next sale: February 2027 annual tax lien sale on the statutory pattern in ARS 42-18112; no dated 2027 sale was published on the official pages found. No dated 2026 sale was found either. The only official confirmation read is the April 28, 2026 Board of Supervisors minutes, in which the Treasurer described the annual tax lien sale as a Treasurer's office function.

Research La Paz 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 La Paz 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 La Paz County

Not verified from official sources. Contact the La Paz County Treasurer's office in Parker before the February sale.

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, La Paz County	No deposit amount was verified from official sources, and none is claimed here.
Payment, La Paz County	No county payment terms were verified. The statutory frame is ARS 42-18116: payment in cash at the time the treasurer determines, within fifteen days after the close of the sale, plus a processing fee of not more than $10 per lien.
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: the statutory assignment route

Under ARS 42-18113, liens that receive no bid are assigned to the state at the 16 percent rate, and under ARS 42-18122 the treasurer sells a state held certificate to any person who pays the whole amount then due under the certificate plus the entire amount of subsequent taxes, with an assignment fee of not more than $10. Whether La Paz County publishes its own assignment list or window was not verified.

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.
