Quote from Pasternak:
Nahh, we have a nasty wealth tax of about 1,2% of your net worth. It kicks in already at 16000 USD. If you have 1000000 in stocks and make 10% a year, the wealth tax is a big deal. That means 28 000 in income tax and 12 000 in wealth tax. Stocks is measured at market price, but real estate has a huge discount tax wise. Therefore much better to invest in real estate compared to stocks. Also too many indirect taxes and too much welfare to pay.
Besides: climate, cost of living (I believe Oslo is top three in that regard) and the experience of living abroad. The bst thing is to buy real estate in Norway (high cost country) but living in a low cost country (Brazil for example). I have a Swedish friend doing that.
