This doesn't do that much for the finance industry since it has to be a cash purchase. Still, I guess it'd drive prices up somewhat. The effect couldn't be huge, though... there's not that many foreigners with half a million bucks cash who want to leave their home countries and reside in the US. On the other hand, given a choice of all possible immigrants, I don't think there's any problem with the US moving "those with half a million bucks" to the top of the list.
