@Publisher, probably depends a lot on the major.
In any case, I doubt UNM is any more affordable.
And right, see how many credits you could bring in to your various options as well.
Bryn Mawr (or UMD in 3 years) may be the best options if you gain employable skills in college. You could potentially find work/internships on/around campus too to knock down costs/debt (probably more possible at UMD). See if the Banneker/Key allows you to keep the scholarship while going PT (or with a reduced load so you have time for jobs if you find them). Gain stats/data science/CS skills.
