You can try to contact that bank;
but I doubt that they will communicate with you:
If they talk to you at all, they should tell you to wait until it is Listed with a local Realtor.
The Banks want Buyers to use a Realtor; they are paying the commission for you, and they are serious about Escrows not falling thru, for any reason.
So, you see, you are not saving anything, there is no way that you are going to beat the gun, and you will need the advice and council of your Realtor.
Good luck and may God bless
