You can enjoy substantially lower costs of living in Portugal if you are willing to live outside of the major cities. The demand for property in Porto and Lisbon has driven rent prices up exponentially. Bragança, Castel Branco, Portimão, Evora, Viana Do Castelo, and Santarem are just a handful of places that are regarded as among the cheapest areas to live in Portugal. Here, you can get by on a monthly budget of less than €1000.
