If you wanna get an apartment you should get in a "Bostadskö" (home queue) right now. Very long waiting time in many places.
Otherwise you will have to buy an apartment, and that is quite expensive.
Where in Sweden are you planing to move to btw?
stockholm is expensive but beautiful city
In Sweden and/or other nordic countries everything is expensive. You need to get used to that. Food is exceptionally expensive...
But good
Nah, it's usually pretty dull
