What I absorbed: housing shouldn't be an investment market, otherwise investors try to suck the money out of everyone. Whatever corner they try to hide.
Their existence in the market doesn't stop you from existing.
Meanwhile we let the Qataris &co buy flats in Europe capitals and keep them empty as investments vessels, I find that much more disgusting that "think of the investors =("
You'll find that it doesn't. That any such restrictions are political decisions not investor decisions.
