@Justin Lester A “deed in lieu” is not something you need or use on the front end…hopefully never. You simply need your purchase to detail the down payment, balance to be seller financed and the terms….interest rate, amortization schedule and any balloon. The Promissory Note and Mortgage document will be prepared by an attorney, or maybe the title company, which you will pay for, along with recording. These are already existing fairly standard forms that the attorney/title company will fill out.
