Barbara Corcoran, founder of the Corcoran Group and an investor in the second season of ABC’s “Shark Tank,” gives The Real Deal a tour of her three-bedroom apartment on 94th Street and Park Avenue, that she bought for $3.5 million in 2000, in the first in a two-part series. Corcoran, a real estate investor and author of recently released “Shark Tales,” lives with her husband William Higgins and two children, 17-year-old Tommy and Kate, who the couple adopted five years ago. She shows us her favorite spot in the 3,500-square-foot apartment, talks about a lack of sex in the bedroom and demonstrates how her son wedges himself into his airplane-size bathroom to shave.
