Tax Delinquent Information - how to get it

[Ryan DeLange]

I would like to do direct mail to tax delinquent property owners in Arizona. Arizona is a tax lien state, meaning that they auction off the lien (not the property) and then the lien holder can foreclose after three years.  The treasurer's office has a CD of the most recent tax avoiders that they sell to lien investors.  

But I don't want to buy a tax lien -  I want to find a list of the people who are still tax delinquent a couple years later and are in danger of being foreclosed upon by the lien holder.  Anybody know how to find this list?
