— New York City real estate heiress, Allison Bandier Koffman, has put down $4,318,275 on an Upper East Side home. The apartment occupies an entire floor of 141 East 72nd Street, a notoriously sought-after pre-war cooperative. Ms. Koffman, a Wharton-educated senior vice president at Sotheby’s Realty, has “real estate in her blood,” according to the company. The heritage lives up to the hype: Ms. Koffman’s grandfather was developer giant Samuel LeFrak, and her mother penned this real estate bestseller. The apartment, which includes a library, a wet bar and a wood-burning fireplace, was sold close to $200,000 beneath the asking price. High-rise low-down indeed.
