Since home loan interest rates ( and IR' s in general) are lower overseas than Australia , what is stopping me from getting a loan from a foreign bank ? Maybe it's nothing but I don't hear of anybody doing it ?
2 factors: A bank has to be licensed to do business in an area to make loans there. And a bank would have a much harder time determining if it would be a good idea to make the loan, and so wouldn't bother with it.
