Deposit rules

Register on RealAuction and obtain a bidder number well before sale day (allow 24–48 hours). Arizona county practice commonly requires a deposit (often ~10% of intended spend, minimum amounts vary by county) — confirm Santa Cruz deposit amount, funding method, and deadline on santacruz.arizonataxsale.com FAQ and with Treasurer before bidding. No walk-up bidding.

Title risk

Liens that survive the sale

Certificate purchase does not clear liens — the owner can redeem until a treasurer's deed issues (after the statutory period). Once a treasurer's deed issues, most private liens are cleared, but state/federal liens can survive.

Quiet title

Arizona treasurer's deeds are widely treated as weak title; most investors pursue quiet title before sale or refinance even when not strictly required to hold the deed.
