Many times banks will list a property with a Realtor, while it is processing the foreclosure paperwork thorugh the courts. If the property sells, the bank does not have to proceed, but if does not sell and the bank gets notiified that the sheriffs sale is scheduled, they will stop accepting any offers and wait for the auction.
It appears this is the case with the property you want to purchase.
You can find out from your county when the property is scheduled to be auctioned, and actually go to the auction and bid on the property yourself! You can also ask your Realtor if he/she can find out the information for you, so you can get all the details of how an auction works, what is expected of you on the dalte of auction, etc.
I hope this helps!
