Knowledge is power / another 'n=1' data share:
IS, non-trad career-changer, LM 72, went to both UIUC/UIC en route to being a fully realized applicant. Additionally, I unsuccessfully applied last year (2017-2018 cycle) and received my pre-II rejection email in 12/2017.
This cycle: Interviewed 11/2/18, notified of my acceptance 3/12/19, assigned campus placement today (3/15/19) (I got my second choice).
They also sent me my financial aid award letter... which for transparency was simply their estimated COA juxtaposed over the Federal Loan breakdown: Unsub-Loan ($40,500/year... the max) with the remainder covered by Fed Grad PLUS loan ($16,236/year, though I know the Grad PLUS max is a bit north of this value), totaling $56,736/year. It is explicitly stated in the letter that this value is based off the assumption of Chicago-campus placement, so my guess would be that no matter which campus you are placed in, you will likely have the same borrowing options as those placed in Chicago.
I'm very excited to have finally been accepted. I highly recommend not putting too much thought into how opaque UofI has been in their correspondence - their sluggishness/lack of transparency is in no way a reflection of your value as a prospective physician. There will be lots of waitlist movement after 4/30 when applicants have to withdraw any additional acceptances, so do yourself a favor and postpone your (perfectly natural) neurosis until 5/1.
Best of luck!
