This is a tough one because, in my opinion, they're pretty similar. The money is a big factor, but if you really want to stay in PNW for the rest of your life, why leave? Also, TC has just as high a cost of living as Seattle.
I don't think going to Minnesota over UW is going to increase your chances of an east coast residency should you desire one (but, again, why do you want an east coast residency if you want to be a PNW lifer??). If you really are worried about that, you can always do aways outside of the west coast to get your foot in the door so it makes you competitive for non-west coast residencies.
From what I see, your case is very much a what-does-your-gut-tell-you situation. I don't see any pros/cons weighing heavily in favor of one school or the other.
