no one ever sells a profitable business. people only sell business's which are losing money or just breaking even. if a business is making money, and the owner is sick of working, they usually install a manager to run things, and the owner sits at home and collects the profits.
Not sure if this is accurate for me. I was offered to sell my buisness which WAS making money by a competitor. It does happen, companies do it to gain a larger slice of the pie and to remove a competitor.
