Arizona Tax Lien Investing: A Complete Guide
Actualizado Oct 8, 2026 · Este artículo está disponible en inglés.
Arizona combines a high maximum rate, a growing population and online sales, which makes it a popular second state for lien investors. Its key difference from Florida is what happens if a lien is not redeemed: in Arizona, the holder must go to court.

The interest rate: up to 16%
Arizona allows up to 16% per year on tax lien certificates. The actual rate on each certificate is set by the bidding at the annual sale. Interest accrues until the lien is redeemed.
The annual sale
- When and where: counties hold their sales early in the year, and most sell online. Check each county treasurer's site for dates and registration.
- How bidding works:
- Bidding opens at the 16% maximum.
- Bidders offer lower rates.
- The lowest rate wins.
Your cost is the lien amount, so there is no premium to lose. Competition, especially in large counties such as Maricopa, can drive rates down sharply on attractive parcels. Set a minimum acceptable rate before you bid.
Over-the-counter liens
Liens that do not sell at the auction can usually be purchased afterward from the county treasurer, often at or near the maximum rate since no bidding drove the rate down. Availability and process vary by county. As always, ask why a lien went unsold before buying it.
Redemption
The owner can redeem by paying the treasurer the lien amount plus accrued interest and fees, and the treasurer pays the holder. The owner's right to redeem continues until a foreclosure judgment is entered, not just for three years.
If the lien is not redeemed: court foreclosure
Arizona is a judicial foreclosure state for tax liens.
- When: the holder may file a foreclosure action in superior court starting three years after the sale. Before filing, the holder must send the notices required by statute.
- What it involves: a lawsuit against the owner and other interested parties, usually with an attorney. If the court grants judgment, the treasurer issues a deed to the holder.
- Cost and time: attorney fees, title reports, service and court costs, and a timeline that depends on the court and whether anyone contests.
- Benefit: a court judgment generally provides a strong title.
- Deadline: if the holder does not foreclose within the statutory period (ten years), the certificate expires and the investment can be lost.
Subsequent taxes
A certificate holder can usually pay later years' delinquent taxes on the same parcel ("subsequent" taxes). These generally earn the statutory rate and protect your position, since you must pay them before foreclosure anyway. Check the treasurer's procedure.
Is Arizona good for beginners?
Good for income-focused investors; be cautious about property acquisition. The high maximum rate, long accrual period and over-the-counter access make Arizona attractive for interest income. The court foreclosure process means acquiring property takes more money, time and legal help than in Florida.
Tips
- Calendar the three-year foreclosure date and the expiration deadline for every certificate.
- Research the parcel even if you only want interest: a lien on worthless land may never be redeemed, and foreclosing on it can cost more than it is worth.
- Use LienDeed's scores, computed from county data, to prioritize research, then confirm on the county's official records.
