short term seller financing

[Jasmine C.]

I have a property I want to seller finance to a prospective seller but I have never done a seller financing deal. I am trying to learn what is fair for myself and the potential buyer. it is a SFH 3/2 that is currently rented for 1175 with a year long lease. good condition in a ok neighborhood. The buyer is not able to get a loan because of high DTI and is working on selling off some non performing properties to become eligible to get loans again. This will take a year so they want a seller financing for only a year. The property is worth 100-110k with a 63K mortgage of 4.3% on the home. They can put 5k down now but once their properties are sold they will have enough down payment for a traditional loan when they get their own financing in a year.   They want to own it on title and we want to keep the mortgage in place until they get their own financing and have that pay off the loan.  could you help me understand what is considered to be a fair term and price for short term seller financing?
