don't buy any franchise (ever) in my opinion.
its French for restrictive/restrictions on all business practices and a hefty percentage from your gross, n never net income. straight out head office greed n unrealistic practices.
also, people never sell gold mines, they sell tin mines dressed up as gold mines. if it was a real gold mine, u you hire a good manager n a few staff n sit at home for life n collect the royalties. my father was a real estate agent for almost 45 years...in all that time he said every one he sold was overvalued n a doomsday waiting to happen...why would u sell a profitable business ?...no, u sell businesses that are struggling or just breaking even with a set of cooked books...occasionally you get a good one (profitable n people retiring after many years, but a one in a thousand, if the odds are even close to that).
and the few brands that do make money, cost millions to get into.....franchises usually are not a healthy way to own your own business n personal life. Just my opinion...
