Short Sale Offer - Bank Approved Price

[Kyle Weckman]

Hi, 

I am looking at two short sales that both have "Bank approved" prices. I was wondering, does anyone have experience offering less and getting it approved? Or do banks hold firm at that approved number? I have no problem throwing out a low ball offer and it being rejected but I wanted to see if anyone else any luck with this scenario.  I am also guessing it depends on the bank... 

Thanks!
