It is true that Remax Orlando is different from Remax San Fransico when it comes to customer satisfaction and service. However, both franchise have a minimum standard to up hold, to keep the Remax name. It is this minimum standard across the board that keeps predictability from one franchise to another. Where as a solely own company must make a name for itself. Usually that name they have created is limited to a local few. "Local" being a general term.
So when a consumer is looking for a company to do business with, he has a choice. A franchise that has an established standard govern by a higher HQ or a local company who's standard is govern by the owner.
Also, When a consumer feels that they have been treated wrong by a franchise, and the local management is unwilling to listen, the consumer still has the corporate headquarters that they could address. If a lawsuit must follow, especially for a large sum, it is easier to go to the deep pocket corporate than the small pocket franchise. Where as local Company has no higher authority than the owner and if the lawsuit was in the consumer favor, there is no guarantee that the owner will have the assets to pay.
