It's been my experience that the banks with upcoming foreclosed properties will not communicate with interested buyers until the property is listed for sale.
I suggest that you keep in contact with the assigned listing agent to determine when the home will be coming on the market and inform him that you wish to submit an offer right away. That way he can communicate with you when the property becomes available for sale. Usually, the bank will perform the needed repairs before coming on the market so that may not be an option for you.
