• Barbara Gutmacher Girard and her mother Rose are teaming up to sell their apartments at the Plaza. The two units on the building's 18th-floor, which Barbara and Rose bought last year for $4.74 million and $3.4 million, respectively, are listed separately for $8.995 million and $5.995 million. Or you can buy the matching apartments as a package deal. Don't expect any sort of bulk discount, however. The two apartments combined are priced at $14.990 million. [Cityfile, BHS, BHS]
