How La Paz County sells delinquent taxes

From lien to deed

Arizona does not hold county tax deed auctions. Instead, a certificate of purchase holder whose lien has not been redeemed may file a judicial action to foreclose the owner's right to redeem, but only after three years have passed since the tax lien sale.

Over-the-counter (leftover) purchases

Liens that receive no bid are struck to the state. Any person may later buy a state-held certificate over the counter by assignment from the county treasurer, paying the amount due plus subsequent taxes and a small assignment fee. Assigned state certificates earn the full 16 percent.

Arizona rules

Max interest rate
16% per year, bid down at auction
Minimum return
No statutory minimum; interest accrues at your bid rate
Redemption
The owner or any interested party can redeem the lien at any time until the right to redeem is foreclosed by the court. A certificate of purchase holder cannot begin a foreclosure action until three years after the sale, and the lien becomes void if no foreclosure is commenced within ten years after the month the certificate was acquired.
Surplus proceeds
If the court forecloses the right to redeem, the county treasurer issues a treasurer's deed conveying the parcel to the certificate holder. Because the property is conveyed by deed rather than sold at auction, there is no auction surplus to distribute.
Governing statute
A.R.S. Title 42, Chapter 18

A tax deed does not convey marketable title. Most buyers file a quiet title action before they can resell or insure the property. See the due diligence guide.
