Could you run the business from abroad? I want to sell up and be a digital nomad. Be good to have some money coming in from a franchise.
Honestly? No. The franchisees would soon work out that you're doing nothing at all for them. Franchising is a partnership and if you approach it as just a way of making money, it'll fall to pieces.
Here's an example. If a franchisee phones, no matter what I'm doing, I'll check if it's urgent and, if it is, I'll deal with it then. If there's a problem with van or equipment, I'll suggest a fix over the phone. If it can't be fixed and is affecting his ability to work, I'll drop what I'm doing and drive to where he is to fix it and, if it's fixable, I'll spend however long it takes to get them back earning again. It's part of the deal.
Bizarrely, renting out work seems to bring in a similar percentage and sounds much more suited to what you're thinking of.
