You are the lender on an owner-financed sale of real estate, carrying the note secured by a lien on the property. The borrower is not complying with the terms of the note. You are now faced with the daunting prospect of foreclosure on your lien.
The good news is that the lien foreclosure gives you a process to recover some or all of the money still owed you. The bad news is that you are going to have to deal with very complicated, tricky legal foreclosure steps to get there.
