College housing and gaining residency questions

We're looking for some answers if anyone can offer insight, experience or help.

Youngest of 4 children is a freshman in NC. We live and work in NY. We found a house to buy in her college town. She is 18, has worked every summer, not working currently. 

Is there a way we can structure this so she gains residency? We'd 'gift' her the house or set it up in a trust. Does her name have to be on the deed to gain residency since we obviously don't live in NC. I'll be doing that research with the college but in the meantime, I thought I'd ask here.
