Finding the Lender

I ran across a house that was abandoned. I finally found the owner and it was a house that went thru divorce and from what he said it had been foreclosed on.

He said he didnt know who the lender was… How can I find this out.

I looked in the usual locations I have before and I cant find anyhting…
Any ideas?

County recorders office. Look for the mortgage and any assignments afterwards.
