How to know if it's been auctioned

[Account Closed]

I noticed an overgrown house down the street from a current rental I have, so I checked it out on Zillow and it's listed as a preforclosure, but also said auction and listed March 2016 as the auction. How can I find out if the property has been sold yet? Is it possible that I still have a chance to contact the owner and ask if he wants to sell? Thanks Patrick
