Buying at Auction in Phoenix, AZ

[Kevin Ferris]

A little background on me. Realtor (3yrs), home owner in North Phoenix. Bought REO property in Scottsdale Sept-2012. Lived in it for a couple of years, now renting it out. Moved into a new Taylor Morrison home in North Phoenix 18 months ago. I like the Phoenix market right now. A lot. So we're planning to buy a few rental properties and hold for a few years.

Currently working on buying a short sale in Phoenix, waiting for bank approval.

Looked at another short sale that has since been turned down by the bank, and is now going to auction.  Looking to possibly buy it at auction.  I'm trying to find info on the process.  Could someone please point me in the right direction?  Do I just go to the courthouse and start asking questions?

I've tried searching these forums without much luck.  Maybe I'm doing it wrong.  Coffee or lunch is on me if anyone knows the process and is willing to let me pick your brain.  Willing to trade detailed market info that I have access to as a Realtor for info on the foreclosure process. 

Thanks in advance for any info or direction!
