I highly recommend looking at what people are saying about the franchise you are vetting at: The Naked Truth Online's Franchise Forums. With over 250 franchises online, you can subscribe to RSS feeds of franchises you are doing your due diligence on. Ultimately, the more franchisees you can speak with within a specific franchising concept, the better. I also recommend utilizing bluemaumau's tools and directories, specifically as they are some of the best in the industry. Best of all.. they're free!
