Thanks Gator! I think I'll wait it out until the last week of July, first week of August at the latest, since that's the soonest I'll be able to get to Chicago to sign a lease in person. I've learned from experience to not worry about finding housing whereever I move. I found an apartment in NYC in 1 day, I moved to Paris with no place to live and found an amazing place, in the best location, in 1 hour. DC is a big city, there are tons of places out there if you're not too picky, if I have to I'll sublet for a while.
What other schools are everyone waiting on/deciding between? I put in a deposit at Loyola b/c even though I haven't visited, I have a lot of friends in Chicago. I'm still waiting to hear from Brooklyn, Cardozo, Maryland and Boulder.
