I cant give you an exact answer as your current financial position is the largest factor when looking at loans. Income, assetts and so forth. My suggestion is to speak with a professional who actively works your state and is familiar with foreigners recieving loans.
Chis Smith with Proficio Mortgages is the person i recomend speaking with.
He is with a national company and has always performed on every loan i have taken to him.
Below is his contact; let him know i sent you his way and he will be able to answer your questions.
