Add family and 100k after taxes in Munich will be no big deal. I could live alone in the car, but the kids might want their own rooms and their own beds.
100k is a unreachable dream for me unless I found a business myself and actually succeed. Munich is expensive, I've seen some prices there. I live near Denmark though so Munich would not be a option in the first place.
I could afford a house considering my savings rate and current appartment rent. Not a big one but it would be enough. Have no reason to buy one for myself though.
You can do over 100k if you freelance but it's risky to be a freelancer in a lot of ways in Germany. Salaries in Berlin and Munich are approaching 100k or over for leadership roles. The problem is COL in both cities is high and Berlin you basically can't get a flat anymore even if you can pay the rent on it.
