Property vacant 10 Yrs. Owner surrendered it.. Opportunity???

[Account Closed]

This is a weird one... any help?  Property vacant 10 Yrs. Owner surrendered it.. County has him listed as owner still BUT lender is paying property taxes on it every year out of escrow for his mortgage that does no longer exists.   Prev. owner says he got a lawyer involved and the lender cannot foreclose on him... Also there is nothing that legally that can be done to remove his name from the title.

He says several investors have called him on it over the years and they brought it to the lender and were rejected as the lender wants top dollar/current market value for this abandoned property.  

Is there any opportunity here for me?
