I just lent a large amount of $ to a friend to help finance a large order he is performing for wall mart. He gave a a note with secured with real estate and automobiles. I am scared!
You made the loan. Unless you can unmake the loan, it's time to see how tasty the lemonade is.*
Loan secured with real estate: does that mean a mortgage, duly recorded in the county clerk's office? If not, then what do you mean the loan is secured with real estate?
Loan secured with automobiles: do you have the title? Is it signed? Is there a lien ahead of you on the title? Or do you have the title and a financing statement that you need to file at the DMV? Or maybe it's already filed and your lien is on the title.
And there is more you might want to do. Is the collateral insured, etc. You could have paid a lawyer to help you before you made the loan. Now maybe you need a lawyer to figure out this mess. It would have cost less to do this right. Beyond asking pertinent questions, though, I can't help you unless you are prepared to engage me as your attorney for real.
