A FAMILY AFFAIR Ken Goldstein and son Ryan worked together for more than five years at an Internet company before the dot-com bubble burst, but Ken (now with Halstead Property) said the two thought they’d never collaborate professionally again. “I said to myself, ‘I’m never going to work with him again,'” he said yesterday. “Let him do his thing and let me do my thing” Never say never: The Goldsteins recently found themselves representing two sides of an Upper East Side real estate negotiation, and Ken said this collaboration went considerably better. Ryan is now with Cohen Smith Chang LLC, and when the transaction was almost complete, “We looked at each other and thought, ‘This was really a good thing to be able to do this sort of thing’ … it was amazing.” The apartment, with southern and northern exposures, hardwood floors, and generously high ceilings, was recently renovated.

WAITING TO EXHALE The physician who bought this 17th-floor apartment had seen a lot of apartments. Many were too close to the street, others let through too much noise, others were in poor condition, and others, well, just weren’t right. Two times he finally did find a suitable apartment, but the deals fell through, Amy Rea of Halstead Property said. She took him to this apartment, with two combined terraces with a view of Central Park. “When the sun streams through there was magic,” she said, describing the space as “loft-like without being downtown.” When her client walked into this space at 392 Central ParkWest, Ms. Rea said, “I knew that he needed to have the property to be happy,” she said. “I heard him stop breathing and just look at the air and enjoy the air.” Luckily, the physician probably knew how to resuscitate himself.

they were renting an apartment they’d already had there. “It was the perfect fit because they already lived in the building and loved the building,” Amie Fields of the Corcoran Group said. After finding the perfect apartment — it had been taken off the market last year because the seller was firm that she wanted close to $1 million and the apartments were only selling in the $850,000 range — the couple found a unit that fit them. The co-op itself has a lot of repeat buyers, Ms. Fields said. “Once people are in it, they like to stay in it,” she said.
