Rafa,
Been here 16 years, you say I get 14000 euros a month?! Really?! I must check my bank statements more carefully.
Look at it from the other end. Ask what you could rent for 50,000 euros a year. Would it be a 4 bed roomed terrace house with no garden in a pilot village (labour camp)? In the US you could buy a house in 4 years with that number and then pocket the cash.
