tax delinquency lists

[Gabriel Soto]

My name is Gabriel and i'm fairly new to wholesaling. I have a small buyers list (which I also need to ask how do I help that grow quickly) and I have a couple leads i am currently working on. My main question however is regarding Tax Delinquency houses. How many have done this in the phoenix area and how long does it take for a house to be completely lost and thrown into auction? Also, where can I find a list on these houses? I tried looking on the county website but I cannot find anything. 

I'd really appreciate the help, thanks!
