Does $72K go far in Sweden? I would assume not due to taxes...? I'm in a position of ignorance so I'm just looking to get a better idea of what it's like there :)
The national median wage is ~$35K ($27K post tax) afaik, and people live good lives on that, albeit in smaller towns.
And if you have a mortgage, you can deduct 30% of interest payments.
That doesn't sound like much help for a single expatriate coming to Sweden for software work. They're going to want to live in a city where there's lots of other people (including other expats) to network with, date, etc.
Note that you don't rent apartments, you buy them. It makes a comparison harder.
