The runner-up last week, at $18,100,000, according to city records, was a late 1830s Greek Revival townhouse at 39 West 10th Street that was sold by the composer and conductor Jonathan Sheffer. This, too, was in white-box-like condition: According to the listing on Streeteasy.com, “the home has been gutted in preparation for renovation, allowing a purchaser to fast-track construction and select all finishes and interior details.”
