Empty State Building
La razón, que sólo el 25% de sus oficinas fueron arrendadas, el otro 75% estaba vacío (Empty)

The building’s opening coincided with the Great Depression in the United States, and as a result much of its office space went unrented. In its first year of operation, the observation deck took in over a million dollars, as much as its owners made in rent that year. The lack of renters led New Yorkers to deride the building as the «Empty State Building». The building would not become profitable until 1950. The famous 1951 sale of The Empire State Building to Roger L. Stevens and his business partners was brokered by the prominent lower Manhattan real estate firm Charles F. Noyes & Company for a record $51 million. At the time, the sale was the largest price ever paid for a single structure in real estate history.
