Meet with the franchisor and meet or talk to several franchisees to see how you'll fit in. When you buy a franchise, your success is assured. Any new business venture involves risk. You must be ready to work long hard hours to implement the franchisor's business plan in order to succeed. I'm sure my banker will lend me money when I find the right franchise.
Bankers are more willing to finance franchises than independents.
However, they may not believe in you or your chosen franchise like you do. If you are gainfully employed now, set up a home-equity loan before you quit your job. I know how to work with and manage people. In most systems, you'll be hiring, motivating, and training several employees. Signing a franchise license will not change you.
