Can I legally use a student loan for an apartment?

Depends on the loan terms - some student loans get paid directly to the school (to avoid just what you want to do), some pay out to you and do not check. Of course, just renting an apartment does not necessarily qualify you for in-state tuition (yes, states check because people do exactly what you are planning).

Before you increase your debt that much, check with your university to determine what you need to do to establish yourself as an instate resident. Usually just having an address is not enough, you may be required to work full time for at least 12 months while not taking classes, or even have to marry a state resident to be considered a resident yourself. It would really be a bad idea to put your plan into action and borrow all that money just to end up not being considered a resident anyway.

You have to find an apartment that will accept 6 months rent in advance with no other job or credit.

I dont believe in unlimited school loans. They should be for the tuition only.

yes. You'd be was ahead though to get a cheaper apartment. When you start paying back the loans, you'll be glad you did.

Don't feel like a victim when you can't pay it back, after for those who read history recessions happen every 8 years.

Yes.
