new question about inspection on an REO

[Account Closed]

We got a counter offer on our bid. We are not sure how much to set our final and best offer at. My question is, does the bank ever re-negotiate after the inspection if something major is found? Our realtor says no but we're not sure if that's set in stone or not. When I say major I mean the well, septic, plumbing... something that is over 10,000 to fix or even more than that.
