Want to buy ss, but seller agent says list price is lowest

[David I.]

I found a home that is a short sale and am considering putting an offer in. 

My agent reached out to the sellers agent and she said the list price is the lowest the bank will accept. 

I find this hard to believe. 

One they already have a negiotaor assigned to the loan packet, foreclosure is slated for early December and banks never want to be a landlord. The fact that they have a negiotaor tells me they have already agreed to accept less than the origibal loan amount. 

The home is located in Dallas, tx and the bank is  bofa. 

Is there a way for my agent to find out the loan amount of the home?

Thank you.
