Whether you buying a new franchise or a franchise resale you need to make sure that you fully assess each franchise business to gain a better insight into the business and the franchisor.
Below is a list of questions you could ask the franchisor or a representative. This is not an exhaustive list, and a lot of it will be covered in the FDD. It will encourage you to think of additional questions of your own to ask, allowing you to build a better understanding of the business.
This is not a complete list; however, it is a good starting point. Remember that you are not just buying a franchise resale, you are also joining a franchise system. You success will be effected by the quality of the system you join.
