Best way to apply a mortgage or any other suggestion?
Here is my situation. I have been working oversea for over 25 years and planning to settle in California soon, very soon. I believe I have good credit with a short period of time living in Los Angeles about 10 years. As I am going back to CA, also planning to purchase a property in Irvine CA, with target price 1.2M. Can I get a mortgage even I will have no job when I move to CA?

Here is what I got:

-USA properties worth 1.2M

-Oversea property worth 3M

All paid off

I know I can sell my property and purchase the Irvine property. But as the interest rate is so low, I want to apply a mortgage. 

I have to plan ahead before coming to USA. Any other way I should do? What do you suggest? Thanks a lot.
