Student Loans - what's the best source?

Maybe, maybe not for private loans, but she’d probably qualify for Plus loans. I don’t think it is a good idea to take out $85k in loans but people do it. As long as OP has not filed bankruptcy, is current on debts (very loose definition) and isn’t in default to the government on other loans, she’ll qualify for Plus loans. She doesn’t need to prove ability to repay or even that she has a job.

She didn’t ask if it was a good idea, she asked which were the best loans.
