As one who has fairly recently franchised his concept but not yet sold a franchise to an outside “franchise owner”, my perspectvie is obviously limited.
I think I’d be most concerned with the quality of the franchised product and the mission/vision/values of the franchise organization. Marketing is great but it won’t overcome an average product and/or a mission which is at odds with your values and vision.
Having recently gained a competitor (franchise)in my market (I have over 15 years of experience), it has been interesting to take notes on what I perceive as strengths/weaknesses of the model.
I think if I were going to choose a franchise, I would add to the two points already made the aspect of REAL support. Many smaller franchises IMHO try to reach out into distant markets and don’t have the support structure to really help the franchise owner when he needs it. As a prospective franchisor, I would not consider locations outside of a certain radius of my current territory, in order to guarantee a certain level of support as well as name recognition.
I would contact existing franchise owners and solicit their input. Are they happy with their choice? Would they do it again? Did they get their money’s worth?
I would definitely look at more than one franchise and I wouldn’t let price be the determining factor. Many times, you’ll get what you pay for.
Good Luck!
