Buying a note: use a contract or bill of sale?

[Calvin N.]

I have reached an agreement with a company that is holding a non perfomring note. It is the first mortgage on the property. I understand that I will have to file the foreclosure on the home and have an attorney that I am meeting with Friday to handle that. Do you use a standard real estate contract to buy a note or just a bill of sale? Thank you for your helpful input.
