Say you want to open your own McDonald’s branch. You pass their financial vetting, get on their waiting list, go through McDonald’s boot camp, then McDonald’s corporate builds a new McDonald’s restaurant on land they own (or acquires land before doing so), then they lease the land to you, sell you all the equipment for the kitchen, the furniture for the dining area, and all the food and other supplies you need.

The prices are set according to their rules, the food is provided to you by them, the recipes are all very simple (you learn them at boot camp), all you do is hire and train the staff and operate the restaurant. You pay McDonald’s for everything, your profits are entirely based on sales, they own the land your restaurant sits on. If you decide you want out they’ll find someone else to take over.

Just as residential real estate has skyrocketed in price, so has commercial real estate (even more so). If you decide you’re out and McDonald’s corporate decides that location is no longer profitable then they sell the property with a large return on their investment.
