Found non-US real-estate companies. In Nordic stocks, I found Wihlborgs, Klövern and Citycon that each have yield of over 6%. I now feel I will invest in a mix of these instead of buying a single property myself.
It's still a lot safer to diversify and not just buy stocks in real estate in your country. Better to diversify it at least a bit by splitting the money e.g.
50% Nordic Real estate
25% European Real estate index
25% US Real estate index (E.g. Vanguards' REIT Index VGSIX)
