Advice on structuring and owner carry deal

[Clayton Clark]

I have an opportunity to purchase a home to flip and the owner is willing to carry his loan on the property while we get the work done.  We would avoid a lot of expense with Realtor, Title and Financing fees this way but I am concerned with the risk.   Does anyone have a good contract or a way to do this?

More background - This would be our first flip, I am a Realtor and confident with my comps and my business partner is a Contractor and is confident on his repair estimate.  I would be the Realtor for the sell and my business partner would be the contractor for repair work. Would it be better to take our profit through a Contractor Work Agreement and Realtor Representation agreement?
