ask yourself, if you have no income.
How can you pay back the loan.
If you can answer that question, I believe many banks will be consider giving you a loan
If you are MBA or medical school students, it is possible to get a loan from banks to cover your tution fee and living expense during your study. Of course, the interest rate may be a little bit higher than the low-interest loan.
If you want to get a mortgage loan to invest in rental income properties, it may be possible if you have a reasonable credit record, a good marketable property, a rental housing investment experience, potential rental income exceeding monthly housing expense (i.e. positive cash flow from investment point of view), and other factors.
