This is a good discussion. If I were OP or anyone else posting here that thinks their market is impossible, why don't you speak with active real estate investors? How and why are they investing? How do they make the numbers work?
Perhaps there has been a huge amount of appreciation over the last few years, and you could've gotten 1% just 5-6 years back?
Perhaps on a risk adjusted basis, and given the EU economic woes, investors are fine with accepting lower yields in exchange for breaking even on cash flows and some appreciation on the back end over a mid to long term investing horizon.
In the U.K., most of the land is owned by royal families and homes are built with land leases. Ditto for Brazil!

Perhaps, like I found out when looking for investment opportunities in Colombia (Medellin), nearly everyone is laundering money by using real estate. London is notorious for dirty money making its way into real estate.
All of these things distorts the investment market.
