@dismalscience said it all.
I'd add that the EU is trying to get Greece's property in two indirect ways.
First, the troika demanded from Greece to privatize some of its public assets. While privatization is beneficial inbenefits the bull market, asset prices in Greece are, of course, at their prehistoric levels. Greek companies are all cash constrained now, and the likely buyer of this discounted property will be other European companies, mostly from the net creditor countries.
Second, the leaked drafts of the troika's new demands asked Greece to put its "valuable assets" in a Luxembourg-based fund. The only point of this transaction, as I see it, is to seize the assets if Greece defaults later.
And, yes, correctCorrect me if my suspicioussuspicion about the latter are wrong.
