We buy real estate mortgage notes for cash.
My customers are folks who sold real estate and took back owner financing where the buyer is paying the seller (vs. a bank).
I am not buying the house, I am buying the financing or paper.
Somehow show money (bills or bag of cash) being exchanged for "a legal document paper titled a "Note".
My customers will have a need for cash now in exchange for their mortgage note.
Again, what I do is exchange cash for a piece of paper (Note).
