First find out how easy or difficult it would be for someone to become a TX resident coming from outside. Will your parents be able to relocate?
Lately TX med schools have become very competitive.
Did you get any price breaks from NSU?
If so, you can consider joining there, prepare well for MCAT and try out. I don’t think they would stop you from doing that.
I generally don’t recommend people making up minds on DO this early. Better to complete undergrad, weigh both options, MD or DO in junior year and pursue whatever is more desirable or achievable at that point of time.
