A celebrity history can often result in an apartment going for more than market value. (Look no further than Jackson Pollock's former loft, which sold yesterday.) Not so, when the apartment in question is a tiny two-bedroom (really one bedroom and one windowless office) rental. President Barack Obama's former pad at 142 West 109th Street, which he shared with a roommate for $180/month each while he attended Columbia, just had its price chopped down to $2,300/month. It was previously listed for $2,500/month. Amenities include a framed picture of Obama standing in the apartment, not looking particularly happy about it. "Please call to see this great deal," the listing implores, "and who knows you might end up at the WHITE HOUSE one day !" Or, you know, any type of house would be nice.
