Put the home up for sale. If you haven't already listed the home for sale and found a potential buyer, then list the home with a real estate agent or put it up for sale on your own. You can note in your ad for the home that seller financing is available.
Create a sales and purchase agreement. Hire a real estate attorney to draw up the agreement once you accept a buyer's offer on the home. If you are working with a real estate agent, the agent can handle the sales and purchase agreement part of the transaction.
Create a promissory note, which deals with the mortgage financing. You should have a real estate attorney do this. The promissory note, once signed by the buyer, is the buyer's promise to repay you in monthly mortgage payments at the interest rate you've agreed to over the term of the mortgage.
Establish an escrow account. The real estate attorney or a title company can do this. All of the monetary transactions for the purchase and sale of the home as well as the monthly mortgage payments are handled through this account. Initially, the buyer funds the escrow account with the down payment called for in the purchase and sales contract, which is then disbursed to you.
Receive monthly payments, which are made to the escrow account. The escrow account holder then disburses the funds to you based on the terms and conditions in the contract. Monthly payments continue until the term of the mortgage is over or the borrower refinances with a traditional mortgage lender and pays you off.
