Now that's a stupid question!
In which way?
An expat per definition is a person who will eventually move home
Its much smarter to save money here and then go home and buy something at home for a fraction of the price.
Or, an expat is someone who is not living in the country of his birth; and may never do so.
I do agree, watching these over-priced apartments advertised for sale in London, Mayfair, Belgravia, they are good value! And the prices were as high as GBP 500,000.
But that, incidentally, would not buy a mediocre apartment on a mediocre condo here!!!

However I do see condo rents falling a lot more than anyone predicted.
