I have a lead on a property that the owner walked away from, I did not realize it at the time but wish I did because I would have bought it right then from them. However I found out about 1 year to 1-1/2 years since they stopped paying their mortgage. They claim its already foreclosed but there are no court cases and the public record still shows them as the owner.

So my question is: They still have a mortgage balance with a crazy amount of past interest due. Anyone had luck negotiating with the bank for less than the full mortgage amount? Maybe ask to get rid of the past interest due? And how would i go about talking to the bank about something like this since I am not the owner? 

Thanks!
