I am in the same boat/ have the same concerns. Have you had any luck? This is my second degree, first time applying for financial aid and I'm freaking out a bit about how to finance school, much less pay the mortgage and bills during school.
I applied in early June. I was waitlisted for the Fall 2018 cohort and thought I might prefer a later start at GWU to another program I was accepted to. Fingers crossed, but the distance/commute from Alexandria is a little daunting.
