I did however just find a report showing the total % of homes that are not owned by citizens per major city.
From Bloomberg: Most Non-citizen Homeowners
The % values range from 2-7% mostly in the 2-5% range.
Now, they say "non-citizen" which Im' going to hazard a guess includes some "non-legal" residents. I'm not sure on that point but I think its feasible. Also notice the largest % figures are in Southern cities in TX and AZ.
San Jose, CA is one city where there are a lot of expensive homes and I've heard there are cash buyers from China. San Jose is at #4 on the list at 5.8%. Now thats a significant % really in a market but its not exactly some sort of flood of foreign money.
