Missouri State

MSU offered me a GA position, but I only have until Monday to accept or decline! I’m struggling to make a decision because I want to go to the school that is the cheapest. I would be an out-of-state at Missouri State. Do I go to the 4 year, in-state school, where I could live at home and do a GA position for the first year or the 3 year school (MSU), where I would have to find a place to live and do a GA position for the first year?
