Foreclosure - Lender starting bid price

I know that a lender has the right to set the starting bid price on a courthouse auction, but is there a limit? Can the lender set the starting bid above the amount that is in default? For example if the amount in default is $75k can they set it to $85k? North Carolina is the state I am wondering about if it makes any difference.

No reason for the foreclosing lender to set the bid higher than what is owed. Any surplus at the sale goes down the chain of title to the junior liens and encumberances.

Yeah right - and as far as property surplus is concerned, going up high than the normal price or value is already wrong.
