Usually, lenders will bid up to somewhere around the outstanding loan amount. And typically, the loan amount is known. If you have an idea for how much you want to pay, and it's much less than the loan amount, you won't bid, because there's no point.
Combine that with typically a very short period before announcement and auction, during which time the borrower may not be compelled to cooperate with due dilligence (or may refuse to cooperate despite having a duty to), and yeah, you're not likely to get bidders. If the property was easily sold near the loan amount, the borrower likely would have done it.
Edit: an article from April claims a loan amount of $83M [1]. Asumming that's roughly accurate, this auction says nobody is interested in paying around $83M for this building on short notice. You need "good funds" at the auction: cash, a cashier's check or ability to do an immediate wire.
