You can make a fairly educated guess by looking at some public record websites:
This will tell you who the owner (or former owner if foreclosure is completed) is. This will also give you the legal description.
then look for the owner (or former) under :
.The results of your search are not the most user friendly you will find but you can look for a record with a "Type" of "MTG" and a legal description that matched the Property Appraisers website.
Some of the mortgage documents will actually show the interest rate (if it was an adjustable rate mortgage) and when the loan term commenced which means you could figure it out with a financial calculator. IF it is a fixed rate mortgage the best you could do is take the date the mortgage commenced and look at a service like http://www.freddiemac.com/pmms/pmms30.htm and estimate what the rate was at the time the mortgage was consumated, then use a financial calculator to figure the aproximate balance.
I estimate it costs a lender $50,000 to foreclose so figure that into your calculations if your goal is to make a "fair" offer.
If you cantact me directly I can provide you this information. You have to have a subscription to a foreclosure service in order to obtain this information or be a member of MLS.

If you just got foreclosed on and this deficiency is against you can try to settle for less than what is owed. Make sure that you get a release from the full amount in acceptance of the lower settled amount and that you are settled in full moving forward. Good luck!
