You seem to have a grip on things, to be honest. I can really see why you like Stockholm, I did too when I lived there ten-fifteen years ago. I miss the bars, the resturants, the theatres, the live music... as I only live 2 hours away, I still visit from time to time. But I usually avoid Stockholm in November. Too cold, dark and damp. Next trip in December :)
Since the thread started with investment themes, a few Sweden-specific pointers:
- Buying stocks or funds can be done in two ways in Sweden- "direct" or in an "ISK - Investeringssparkonto". In most cases you want the later since is both much lower taxes and easier to to your self declaration of these taxes.
- Most major banks have both kinds of accounts, but with different fee structures. The majors are Nordea, Swedbank, SEB, Handelsbanken and Danske Bank. The two main alterantives to these are Avanza and Nordnet. Fees vary. My favourite is Avanza but do you own homework.
- If your going the investing way, stick to low-low-low fee broad index funds. Our options are smaller than the americans, but there are some good ones out there. The one I use is Avanza Zero which is actually a loss leader with a fee of 0%, the downside being that its based on the SIX30RX index which has only the biggest 30 companies in the Stockholm stock exchange in it (but still represent half the value of the exchange in question).
Given your situation, and the fact that the stock market is at an all time high here, I would put more energy into job hunting than investment thoughts at the moment. Once you find steady income, start monthly savings in both bank accounts and in an ISK with index funds.
For biochemistry, I guess that also the Malmö-Lund-Copenhagen area can be an option? Some biotech down there too, and if you manage to live in Sweden and work in Denmark, the financial gains may be good.
