Yeah, Michigan offered me $9K over 3 semesters (rather than 4 since I am doing a dual degree with SEAS MLA) and the MLA offered like $23K. It's the school I've been the most excited about, and because its a state-school, if I can get a GSI/GSRA position, they offer a full tuition waiver for those, but its hard to commit to that when I don't know if I even will get one.
I really want to go to Michigan, as it is the only school so far that I've been admitted to for both L. Arch and Planning, making it possible for me to pursue that path. They also are the only ones who have offered me money so far. Penn Planning is supposed to release that info on March 11, but I haven't been admitted to the MLA yet (haven't been rejected either, go figure) but Penn has an estimated total cost of attendance of $82K a year and is not ranked significantly higher than UMich (Penn is #7 and Mich is #9)
