As a rule you offer them 1 1/2 points per month on the balance to finance. So for every 10,000.00 you pay them 150.00. Thats just for using the money. Generally if you use family's money the only way to avoid hard feelings is for you to get 65% and them 35%. More than fair if your going to spend all the tim managing the project.
A more stringent money man may say " without my money etc.. " He may waive the points and just want 50% of the net profit.
