Hi
yon8293I will give some analysis but you need to search for what it suits you.
Data analysis masters are tend to be among tow things applied analytic or building systems (tend more to be for programmers).
Wake forest is for applied management with some programming language. Here it will give exposure in every aspect in business, which I personally prefer as complement to my experience (again this is me). The university is known. It is private university from the 19th century. The job report is very powerful with many corps recruiting from there.
William and Mary is the opposite as it targets more into systems and programming and algorithms. I do not see any business application. Here it is up to you. Maybe you like this branch. It is good university and job report is promising too.
Although John Hopkins is the most reputable among them, I could not categorize its program at all. Honestly, I did not like it and the job report say 82% in 2017, making the lowest among the other schools. So, I personally would not recommend. As you said the cost of living is too high in DC.
I hope I helped you. My advice is to spend some time into each program to see what suits you.
Good luck
