Where would the money come from - are all equally affordable (ie., your mom isn’t too keen on Brooklyn and NYC, but does the price differential make a difference for her budget? Where would the 10K come from?)
Between RPI and Case, the costs sound about the same (give us the number for the loans at each though). If loans are equal (5.5K max/year) and they’re affordable, choose based on vibe, environment, etc. Have you visited RPI and Case?
