hmmmm...who will provide the outstanding $80K
for your property? Whoever it is, they'll probably want to be pretty sure that you can repay it. A job usually helps to convince that lender.
As a mortgage broker I have come across similar cases such as yourselves. A lot depends on the CURRENT status of your visa as to whether you can obtain a loan today. A colleague and friend of mine specializes in arranging loans for new arrivals (he was once one himself so he knows all the procedures and any likely difficulties you may face). This is a highly complex area. Perhaps you could click on my address above and we could discuss the matter further?
