Find balance on a senior position, open ended line of credit?

[Account Closed]

I am looking at a house where the mortgage is in default and the sheriff sale is coming up. After the sale there will still be an open ended line of credit from the previous owner. The LOC is $25k and was originated in 1999. I would like to know what is owed on this.

Any thoughts.  I am thinking  there is no way of knowing but thought some of our venerable members could help.

Thanks.
