Title risk

Liens that survive the sale

Buying a lien does not convey the property — it's a certificate of purchase. The owner can redeem at any point before a treasurer's deed is applied for (after 3 years), so no lien is 'cleared' at the certificate stage. Once a treasurer's deed does issue, most private liens are cleared, but state/federal liens can survive.

Quiet title

Arizona treasurer's deeds are widely regarded as weak title; most investors pursue a quiet title action before attempting to sell or insure the property, even though it isn't always a strict legal prerequisite to holding the deed.
