A low $ may be good in the short term, but it's a risky strategy if anything goes wrong and it can't be turned back around in the next 12 months or so
If foriegn investors pull out of bonds and use the added buying power to get into the US property market it could see inflation become an issue that keeps the dollar down for a long period of time.
Hard to make the scenario of a low dollar for the next 5 years or more sound good
I bet it's been years since inflation was an issue in the US? And after years of fairly stable currency strength it's very likely there is already a rush of foriegn property investors enticed by the sudden advantage they have over local buyers.
