Find out of the school has a different COA for the different living situations as not all schools do.
Find out if the FA will refund money to you if there is excess. My daughter’s school would not refund school funds, but Pell and loans and some outside scholarships could be refunded. My daughter also had two state scholarships that were restricted, the Florida resident could only be used for tuition and BF could be restricted as the college chose. Her school restricted BF to only tuition. If she had lived on campus her last two years, it would have been paid for but they would not give her that money to live off campus.
I know DU has a housing grant, and it can only be used for dorm housing.
