I might be able to help you on this a bit. I have been in the process of paying off the previous owner since we made our agreement a bit over 2 years ago. He was actually a pretty good friend of mine, so it made it 100 times easier for each of us to go into this trusting each other. Here are some of the intial thoughts/questions I would consider…
Before advertising that you will finance to the public, do you have any current employees that would be ready to take that step? I had been at my restaurant for about 10 years, so the seller had that long to build up trust that his investment was safe. You will have much better idea who you can trust from a previous working relationship as opposed to interviewing random people.
Make sure to have YOUR lawyer draft the agreement. As stated above, dont allow any changes to price, interest, length, etc.
Be careful not to overcharge or undercharge your monthly payments. I bought my place about 3 months before the recession hit our area so my payments are based off pre-recession sales/numbers. If I were to pay the place off tonight magically, and want to sell through owner financing, I would only expect about half of what I currently pay monthly due to the struggling economy. So find a safe medium for both parties.
Definitely have a clause where you retain some ownership in equipment. If I knew I was close to default and would be losing the place soon, I would sell off higher priced equipment and give him back an empty store.
If the new owner fails, the business will probably be completely worthless at that point. You might have to find new vendors, be months behind on rent, have no customer base remaining, etc.
If this helps at all, I’m paying a 9% interest rate. I paid 15% down and the loan is over a 7 year period. That is from a 2008 purchase.
I hope some of this helped!
