Czech verdict
The Czech Republic usually works when housing does not eat the margin first
In most Czech scenarios, city choice changes the answer more than daily basics do.
Czechia works when
Income still leaves room after Prague rent, deposit, furnishing and the difference between capital-city life and a Brno budget are priced honestly.
Czech pressure starts when
The plan assumes Prague costs but keeps a reserve that only works in a calmer city.
How much Prague changes it
A lot: Prague, Brno and Ostrava can turn the same income into three different relocation answers.
When permits matter most
It matters most when employee-card or trade-license burden lands on top of a city budget that already feels close.
