What is the closest to a foreclosure you've heard of a bank postponing the sale?

[Kris Fox]

There's a foreclosure sale happening in my area in two weeks.  A few of these properties look distressed from the outside and based on what is owed and the likely BPO, I feel they're excellent candidates for a short sale.  What are the chances a bank postpones the sale this close?

Another question I have is I am a licensed realtor and an investor.  Are the banks going to have any problems with me being the listing agent AND the buyer?  Do you think I would get the 6% if so?
