I won't need a mortgage
Fair enough so, well done :)
I thought the average salary in Poland is 3.5k per month
COuld be, but the minimun is around 2000zl.
Depend on the area, where I live the average is more like 4500.
Numbeo is a pretty good website for comparing different cities:
From my own experience, I came here 6 years ago and lived on around 2500zl a month, I didn't save feck all, but I was fine. That lasted about 2 years but since then it's the gravy :)
Hope you enjoy it........and don't forget; Winter is Coming :D
