I think a food for thought could be reaching out to research mentors at UMich this summer and do research with them over the Summer (maybe after M1) and also doing multiple away rotations there. I know mentors that have went to Michigan State than have gone on to do residency at top places like Stanford so its a great school! You can definitely mention that you were an accepted student there and I think could be receptive (know similar stories of accepted and non-accepted students that do this with top schools near there area; think like NYC and Boston and others too)
I think 200k is a justifiable price to pick UMICH here, but I also am picking a lower-ranked school over a higher-ranked school for the money lol.
Best of luck to you on your decision!
