Billionaires' Row

A stretch of 57th Street between Park Avenue and Broadway has produced, in a decade, the tallest residential buildings in the Western Hemisphere and the highest prices ever recorded for a home in the country: One57 in 2014, 432 Park a year later, then 220 Central Park South, Central Park Tower and 111 West 57th Street.

The deeds here are unusually instructive, because so many were sponsor sales followed by resales at a loss. The records show the premium for a park view, the discount for a building with defects, and what happened to each tower when the first owners tried to sell.
