To stop foreign money (China), from buying homes in the USA and inflating home prices.

We need to stop China and other foreign countries from buying US homes as investments. The prices are increasing rapidly and this will only end up with another bubble. US citizens will not be able to afford homes again as we are just coming out of a disaster. They are buying homes with cash, then refinancing with banks to liquidate their money. Once the bubble pops, we will be left with another recession and banks needing another bailout as the foreign investors take their money and run. Also, if the home is sold for a profit, they probably won't have to pay the capital gains tax that US citizens would have to, thus taking the money out of our country.
