If you follow the classical mantra 'location, location, location' and invest regularly in prime real estate, or, according to your economical level, in a company or fund that does this, what can go wrong?
Would this be a better alternative to governmental bonds (of reliable countries like the USA or UK)?
That is, is this A. extremely reliable, B. offer low but better return than bonds or inflation?
Add-on after some answers: I really mean prime real estate, like the financial district of cities like LA, NY or London. Not some new urbanization or some borough that's getting gentrified and it's the new hot thing. By regularly I mean, not buying when everyone is also buying, but consistently buying, which would imply down and up turns that compensate.
