As someone else posted, moving to Colorado this summer won’t get the student in-state tuition. You have to live in the state for at least a year I’m sure.
FYI, out-of-state student tuition at the U. of Colorado in Boulder is well more than $50,000 per year.
My sons attends the U. of Denver and loves it, and we’re out-of-state. DU is a private university.
