In-state versus OOS for UM I guess is a good deal for specific major or what the school offers the student versus what they can get elsewhere. My time ran out on editing my post. A friend’s son, high stat, was OOS for UM, and he did have to take out student loans because it was more than they had budgeted for his college - but he did well with his career. With many students, choosing which graduate track to go - MD or law - he gained life experiences using his UG fields of study and did end up deciding law. He was admitted to Harvard and two other prestigious law schools, Columbia and I can’t remember the 3rd. So he is doing very well.
Like I said, it is up to the parents and the student to decide on best fit.
