House of the Day: 10 Schermerhorn Street

This two-family house at 10 Schermerhorn Street is a pretty serious pad: lots of original detail, a three-story, 20-foot deep extension and the option of a private parking space. The owners of the 5,000-square-foot house, however, don't appear particularly motivated, judging from the fact that the asking price of $4,250,000 hasn't budged since the house was originally listed last November. What do you think it should sell for?
