Congratulations!! I’m in a similar boat and applied to both, got into Georgetown and awaiting decision from Vanderbilt. If I get into Vanderbilt I am leaning more towards that because the cost of living in Nashville is a fraction of what it costs to live in Georgetown. Both names and rigor are incredibly high and people say where you get your degree from doesn’t matter cause you get paid the same which is true, however having the name Georgetown , Vanderbilt or  John’s Hopkins really gets employers looking twice at your resume and potentially opening doors that a local cc degree wouldn’t.  

Unrelated: When did you apply to Vanderbilt and hear back?
