Does anyone have knowledge of the basic guidelines Huntington tries to follow to recover on a loan when they are the second in position?

I am a buyer in a SS, the First is Bank of America, and they are offering 3K to release the second lien.
Listing agent is saying Hunting wants 8K, or an additional 5K note from the seller, but seller won't do it.
I upped the offer by the 5K, hoping to keep BOA's net the same and route as much as possible to Huntington.

Any ideas on what Huntington might actually settle for?

On a side note, I just found out Huntington held the second. I bank with then and was considering financing through them. Any thoughts if that might persuade them?
