I am not ethnically from Sweden but it is defined in my tax file as the "center of my economic interest" :D. I was born in Croatia, but my husband (and both kids) are Swedish and we lived in Sweden, we have an apartment there, family, friends, we always thought we'd live there. Then I got a great job in Luxembourg so we moved but I generally assume we would retire in Sweden. Husband is getting more skeptical so maybe not but oh well, still I know the system fairly well and I always imagined Norway to be a richer and less leftist crazy version of Sweden (i.e. I often think that if Sweden manages to self-destruct with their communist mantras we'd go live in Norway instead, if Norway will still be letting in Swedish citizens).
What I meant is also that if you look at it, if you're ok with frugality in old age, it doesn't really matter how much money you have saved, as even if you live until 100, state pension will make it possible for you to live, and you can burn all of your savings on travel and fun long before that.
Of course I'm not advocating sponging off, I just mean it is a sense that it is simply far more secure to live in Scandinavia than in Trump's America or retiring early in Thailand etc. So no way would you need the same amount of savings to be able to play around a bit.
How old are you? Yes, your job is very specific, that complicates things.
Would you be able to move into a cheaper primary residence? I.e. sell the house and get something cheaper, thus liberating some funds?
Or maybe take out a loan against it and buy some rental properties abroad, we were thinking of doing that and buying some stuff in Croatia. The math seems quite profitable but we are a bit lazy to do it right now (facepunch).
