1. Do we have a lot of Foreign Investors buying a house with a loan? I know that they pooled some money to buy a lot of properties in the US, but I don't know how many percentage of foreigners bought the properties with the loans. 

2. Will it make a big impact in the US housing market if those foreign investors stopped making a loan payment when they have global crisis? The reason I asked because I have a current tenant who was forced to move out (by the Lender) 3 months ago from the house which owned by foreign investors, and it turned out they stopped making a loan payment even though the tenant paid the monthly rent. Imagine if we have thousands of foreign investors do like this.
