she will be an international student so that is what will complicate things. she'll be doing her undergraduate studies as an international student, so I think I'll have to take loans for her to cover her tuition, books, etc.. also if you're married you've got to take a break now and then, so there's some traveling expenses too, and other stuff i suppose as well. Her parents wont help out of course, because the country they live in has it off pretty bad financially.
Getting out more loans for her education is going to get really expensive and will get really hard on you really fast. I think you need to go speak to a professional finance person to see what you're going to have to do, because I think it may be completely impossible.
The main things I would think about/worry about if I were you is:
1) Between your very high tuition and taking out non-student loans for her education you are going to be TERRIBLY in debt by the time you finish school. Forget the travel expenses, breaks, and other frilly stuff. You can't afford it. Several extra thousand dollars a year for the two of you to fly to her home country will just not be possible.
2) Find out if getting enough loans to cover both of your educations is even feasible. At some point the bank will decide you have enough credit on your behalf and will stop giving you money - and you don't want that to occur in the middle of your educations - again you need to speak to a professional to see what kind of loans you'll be able to take out for her.
3) Consider having her work for a few years (if its feasible for her to get a work visa) so you have at least one income. This might not be necessary-but you'll know once you talk to a loan counselor.
4) If none of these things are options maybe you should take a year off medical school to work and save up some money to afford her education and yours. Or try working part-time in med school but I hear thats killer.
But you really need to get to a bank and talk to someone who knows about loans. I really think its going to be financially impossible for you to take out 70k a year for your medical school education plus 20-30k for an internation undergraduate tuition. I mean just for your education you're already taking out about 30k of non-goverment loans so you better have good credit. Taking out 20-30k more per year in non-educational loans for her to go to school might be completely impossible.
EDIT: Just realized by total living expenses you meant everything. My point still stands that you'll already be taking out your max federal loans and dipping into private loans. To take out more for her will get hairy.
