Hi -
Congrats again to both of you!
Off-campus housing may be difficult to find from far away (can't see the apartment, etc), but I was able to do much of this online. The earlier you start, the better luck you'll have. I got my place in July last summer, and found very few apartments ready for August occupancy. So... if you can't make it to B'more before the end of the summer, I'd hit the internet and start calling landlords. Definitely check out the Citypaper (www.citypaper.com) and the B'more Sun (www.sunspot.net) for local listings. All of the big apt search engines (www.rent.net, etc...) will generally only have the big apt complexes listed. I have to recommend my neighborhood -- Bolton Hill (www.boltonhill.org) -- rental listings are on the website. It's close to downtown, and you can walk to the subway (goes to Hopkins) and the light rail (goes to BWI). Lots of people live in Charles Village, Mount Vernon, Fells Point, and Canton.
Hopkins *does* have an off-campus housing coordinator (in Reed Hall) -- you can call the front desk at Reed and be transferred to her office. She helped me out quite a bit.
As far as Reed goes... around 40% of my class started out living in Reed this year. You won't be ostracized for living off-campus. 🙂 Of those people, all but 3 or 4 lived in the east wing suites. More and more people moved out as the year went on (cheap rent in Baltimore - esp if you have a roommate!). The east wing *is* being renovated this summer, so I have no idea how it'll look in the fall. The east wing usually fills to capacity, so if you'd like to reserve your room, you should do so early. Most people who live in Reed are satisfied, although I think it's mostly due to the convenient location, cheap rent and community (great way to meet your class).
Good luck! Feel free to e-mail me if you have any questions.
