Once upon a time, Barack Obama was a normal college student attending Columbia University in NYC, living on the Upper West Side, and paying $360 a month for a tiny room. That time was 1981, and in 2012, the apartment's rent is $2,400 a month. Like many imperfect Manhattan walk-ups, it has a galley kitchen, a 7x9-foot bedroom, a buzzer that doesn't work, and five locks on the door. Luckily, Obama can call the enormous White House his home now. AOL's got the video tour of his old digs below. [Curbed]
