Sheriff's Auction Bank Bid Estimate on HAMP Property

[Brad Havens]

I'm looking at a Sheriff's Auction for a property which was refinanced under the Home Affordable Modification Program (HAMP).  The result of this refinance was two separate principal amounts, a 'current' principal amount which was set up for repayment under a fairly normal principal/interest amortization schedule, and a 'deferred' principal amount due as part of a balloon payment at the end the mortgage period.

I'm trying to figure out which amount the bank is likely to bid on this property.  Is it the full amount (both principal balances) or just the 'current' balance?  I ask because looking at the court documents which have been filed during the foreclosure process, the bank lists both in it's initial filing, however in the document stating the judge's decision on the case, it only specifies the 'current' principal amount as the amount in the judgement.  I would assume the bank doesn't care what the judgement says and that they'd be likely to bid the full amount during the Sheriff's Auction, but I just wanted to double check and see if anyone else had experience with a situation like this.  Is there any reason why they would bid less than the full amount in this case?

Thanks!
