Do you have a family, by any chance? I've been thinking about moving to Portugal, some smaller town but not too far from Porto or Lisbon, but I don't really know how much a family would need. (I have a wife and 2 kids)
I have family, but they are based in Germany, but everything depends IMO if your kids are able to speak Portuguese or not. That for sure would impact your budget for education. Living in Setubal/Almada, you can plan a 700-800 euro/month rent, 300-500 for supermarket, 100-300 transportation and then education in case your kids need a private school. The costs with transport may vary if you have to commute daily to Lisbon, if you use car or not and etc.
Hey, thanks for the reply! My kids are fluent in Portuguese and I would probably enroll them in public schools. So you think a 2500 monthly budget for a family of 4 would be doable? (I raised your estimates to account for emergencies, healthcare, etc - btw, sorry for bothering you)
