Unless wineguy has found a smaller and cheaper location in Spain, if the "high COL" is the reason is the reason he would leave Argentina, why would he or anyone else set their sights on any city in Spain that might be comparable to Buenos Aires?
Especially if the following is accurate:
| Cost of Living in Buenos Aires is 18.9% lower than in Madrid (excluding rent) |
| Cost of Living Including Rent in Buenos Aires is 31.6% lower than in Madrid |
| Rent Prices in Buenos Aires are 56.8% lower than in Madrid |
| Restaurant Prices in Buenos Aires are 2.4% lower than in Madrid |
| Groceries Prices in Buenos Aires are 15.4% lower than in Madrid |
| Local Purchasing Power in Buenos Aires is 56.4% lower than in Madrid |
You would need around 3,285.0€ (3,850.2$) in Buenos Aires to maintain the same standard of life that you can have with 4,800.0€ in Madrid (assuming you rent in both cities). This calculation uses our Cost of Living Plus Rent Index to compare the cost of living and assume net earnings (after income tax).
