We are Americans & already have a house in Mexico, that is our next stop. Not sure if we will stay there permanently its more of a vacation spot for us. You can get Mexican residency pretty easy you can prove income & there are some other ways. Its temp for 4 years then a small fee to go permanent

The question is how do we get residency? We love Spain but unless we get some kind of residency we will have to leave every 3 months
