I have done some research on this topic. It all depends on the specific franchise that you are looking at. Read the fine print in the franchise agreement to get all the details, as they are all different. Usually the franchise must approve any sales involving the franchise. As far as making money, unless it is an established location with reliable employees and management that is willing to stay on, you will need to spend considerable time to get it off the ground. It is very easy to turn a successful location into the ground with poor management. There are many successful people who have made good money buying these unsuccessful locations and turned them around. I would suggest PMing Too Old, he is a Burger King franchisee.
