I want to apply for a nomad visa in Spain next year. I have 1099 income and make pretty decent income. Currently I live in one of the most expensive cities in the us and just getting over the us. I travel to Europe at least twice a year and spent 6 weeks in France this summer so I love Europe. I know not all europe is the same but just giving some context. I am mexican American and speak fluent Spanish. My only concerns are taxes might be high, racism towards Latinos in Spain, and finding a nice rental. I am not really losing anything moving there I can always come back but moving international is just a bit scary.
Just a heads up from a non Spanish living in Barcelona. Housing in Barcelona is fucked up, probably like a lot of major cities - Overpriced rent and scarcity of places to rent. Just make sure you have enough salary and you have looked at all the not so good aspects of living in Barcelona as well.
