I think we need some clarification and a little more to go on so that someone might offer suggestions of value. "Planning to work" means seeking employment or starting a business? To get a job you need a resident visa with a work authorization, same for starting a business-- unless it's strictly online and your product and customers are outside Mexico. Far as where to live, depends on what your requirements and preferences are: big cities or small towns. access to air travel. coast or elevation. expat enclave or only-******-around.I am planning to work as an expat in Mexico. So do you have any idea which part/city of Mexico is more suitable for expats?
