Yes, it would depend on what type of business it is. My husband was thinking of buying a business at one time and we structured it as a small down payment and then a percentage of the profits for a certain amount of years (or a payout of $XX within the next year or $XXX in the following year). It gave us the oppertunity if business was booming and we came into some money to pay him off and stop giving a % of the profits as well as gave him more money the longer he wasn't paid off.
I hope you can make it work for the both of you!:7
