The closing costs: What it takes to please New York City’s elite real estate …

In a city where a 300-square-foot studio can go for $300,000 and 15,400-square-foot penthouse for $118 million, Lecole has sold everything from a $350,000 apartment in Chelsea to a $20 million townhouse in the West Village. Some of Lecole’s clients are investors looking to buy a two bedroom, two bath condominium in NoHo and rent it out; others are families seeking large homes in Brooklyn Heights.

No matter where they fall on the totem pole, brokers make between 5-6% commission from a sale, split halfway between the seller’s broker and the buyer’s broker. Success depends on getting those expensive properties. And they fight for that 6%, says Lecole.

Her specialties are her own area in Harlem and former neighborhood, the Upper East Side. In Harlem she sold 10 homes in 2014. She was named Carnegie Hill Salesperson of the Year for 2009 and 2012.

“Her acumen, particularly about the Harlem area, was quite striking,” says Eugenie Jacobson, a client who bought a home through Lecole in 2013.

Lecole took Eugenie and husband Derek to see about 10 homes. They ultimately found their 119th Street townhouse a month and a half into the process. (Finding a home can take anywhere from one day to 12 months or more, depending on the client.) The spacious, four-floored home was built around 1903. It features sprawling wood floors, nine fireplaces, brick walls, a dumbwaiter and gryphons chiseled into the staircase’s original wood. They bought it for $2.82 million and, after a year of renovations, will be moving in 2016.

Lecole’s own home, built circa 1900, features original wood doors and floors, 14-foot ceilings, a nook on the staircase where servants would sit (“I don’t have any servants,” she says) and colorful photos and paintings by friends and artists Victor Matthews and Joelle Deroy.
