I would expect them to be like every other bank out there, you MUST go thru their listing agent. If it's not listed, it's not on the market and they will not talk to you until it is. Sorry, but this is probably not what you want to hear.
From what I "hear" they are just putting their finishing touches on their REO department and will lilkely have something on their website pretty soon. Sorry for being so vague, but although from a credible source, I got vague info myself.
