Keren Ringler Brings a Scientific Method to the Art of Real Estate

Keren Ringler began her professional life as a medical researcher, working at Manhattan’s world-renowned Memorial Sloan Kettering Cancer Center. When the South African native decided to become a residential real estate agent, she found that many of the skills required for the exacting work of science were happily transferrable to the often-painstaking process of purchasing property in New York City. Co-op apartments, in particular.
“You have to look at all the factors and variables when you’re trying to match a client with a building—and if it’s a co-op, with their board,” Ringler says. “I don’t find a board’s demands or quirks upsetting, although my clients might. All I know is you have to come up with a solution, and that’s what I work on. I’m very good at problem-solving.”
It's well known, given her success in handling those transactions in buildings such as 750 Park Avenue, 1133 Park Avenue, and 1 Sutton Place South.
“Every co-op is different, and often they can be very idiosyncratic,” Ringler acknowledges. “But they’re the ones who live in the building. They need to have their own rules and guidelines.”
She is careful to prepare her clients for what can feel like an overly invasive experience, given the amount of personal detail required for an application package.
“The process of becoming a shareholder is very off-putting,” she says. “But I try to keep my clients focused on the long-term gains after they’re successful.”
Ringler firmly believes in emphasizing the positive in her clients’ applications, as well as knowing who the board members are and what their interests might be.
“You need to understand what they’re looking for, and then hopefully we can build a match with my clients, by emphasizing things like their charity work, children’s school, and cultural or athletic activities that might appeal to certain members,” she advises. “Assuming a client clears the financial hurdles, what I try to emphasize is their character and personality: who they really are.”
A Special House for a Special Buyer
Though based in Manhattan, Ringler has always prided herself on cultivating a diverse portfolio. She’s just co-listed an extraordinary architectural gem with fellow Elliman agent Kyle Rosko in the Hamptons—a long way from any co-op board. It’s a rare legacy oceanfront home at 15 Dune Road in Bridgehampton, for $45 million, and Ringler is thrilled.
The location itself is spectacular. The house is on another level. Designed by Mark C. Matthews Architecture in collaboration with D'Apostrophe Design Inc., led by Francis D'Haene, the 7,000-square-foot home is set on nearly two acres. Its graceful, linear layout extends parallel to the shoreline, which means every principal room gets to have ocean and bay views. From the first level to the third, the connection to the landscape is constant and uninterrupted: the ocean and the beach become part of everyday living.
“With the owners having major connections to the art world, it’s pretty special,” Ringler says without compunction. “They knew what they wanted. A house with this level of thoughtfulness, mindful design, quality and scale, all right on the beach, is very hard to find. That it offers sunrises over the Atlantic Ocean and sunsets over Mecox Bay makes it even more special. It demands a special buyer.”
I get the feeling Ringler is very excited by the challenge. With the well-earned confidence and experience of an agent whose clientele is equal parts buyers and sellers, she will no doubt bring her meticulous, methodical approach to positioning the property and finding the right buyer.
