I am not a business person but have a good friend that is, and has sold businesses before. She has told me there is a formula (there is probably more than one) based on the business's annual income, of which you pay a percentage as a purchase price of the business. I understand that having a written business plan is a must and I would agree that it would be wise to seek professional assistance from someone who knows business. Also, check out the term "blue sky" and how it applies to a business's clientele. This in itself could be a vital consideration.
On the other hand, it is well-known that one of the greatest obstacles to making a dream come true, are the people in your life that tell you, "you can't do it." Maybe with the right prep, accurate knowledge, and operating on reason rather than emotion, maybe you CAN do it. Â
Good luck!
