Nassau's luxury market keeps climbing. Here are 2025's top home sales.

A former Quaker farmhouse on a sprawling, nearly 20-acre estate was the most expensive home to trade hands in Nassau County in 2025, according to a Newsday analysis of data from Manhattan appraisal firm Miller Samuel.

While the $13 million deal was less than last year's record-breaking sale of a $21 million Old Westbury estate, the transaction is another example of the strength of the luxury home market on Nassau's Gold Coast.

"The price trend phenomenon across Long Island — whether it's Nassau or Suffolk — was characterized by rising prices and inadequate inventory," said Jonathan Miller, president and CEO of Miller Samuel.

Since the pandemic, Nassau's median home price has steadily risen, and this year, the luxury sector yet again reached record or near-record highs, Miller said.

Miller defines the luxury home sales market in Nassau as the top 10% most expensive homes sold. That upper end of the market saw its median home sales price reach $2.42 million in the third quarter of this year, the highest median sales price Miller has seen since he began tracking that data in 2015, he said.

The limited number of high-end homes helps existing properties command high prices, Miller said. That's particularly true of hard-to-get homes, such as waterfront houses, which represented two of the top five most expensive homes sold in Nassau this year.

"Long Island and the North Shore is a hot area, and there's a lot of desire. But there's not a ton of inventory," said Kimberly Bancroft, an agent with Daniel Gale Sotheby's International Realty, who sold one of Nassau's top five most expensive homes this year.

Wealthy buyers have also benefited from strong performance on Wall Street and higher bonuses, giving them more to spend. And because these buyers have other sources of financing than a tr aditional bank loan, like lower interest debt backed by their other assets, they are less impacted by higher mortgage rates, Miller said.

All of these factors have widened the gap between the luxury market and the rest of Nassau's housing market — to the point where, for a home to be considered part of the luxury market, it now has to garner an even higher sale price, Miller said.  

The top 10% of home sales, which Miller defines as the luxury market, started at homes that sold for at least $1.85 million in the third quarter of 2025. That figure was the highest he's tracked since 2015, and a 10.4 percent increase when compared with the third quarter of 2024.

"It's not that the overall market isn't seeing price growth," Miller said. "It's that the higher end is seeing more." 

1: $13 million: 67 Feeks Lane, Lattingtown

This farmhouse-style home situated on nearly 20 acres of Locust Valley land sold for $13 million in May, making it the most expensive home sale in Nassau County in 2025.

The house sports seven bedrooms, nine full bathrooms, three half-bathrooms, a pool house and guest cottage, according to a listing for the property.

Margaret Trautmann, a real estate agent with the brokerage Compass who represented the seller in the deal, said the home was built as a Quaker farmhouse in the late 1800s, and also holds a library, an attached six-car garage on the main house, and walk-in closet off of the orimary bedroom that anyone "would die for." Plus, the property holds a caretaker's house with an attached two-car garage.

Trautmann declined to share the identity of the seller, but she said they decided to part with the home because they visited it less often now that their child had grown up.

"It was a very emotional sale, because they just adored this house," Trautmann said.

The home's new owners, a family with young children, will get to take advantage of the property's pool, tennis court and four-hole golf course, designed by Bill Coore of Coore & Crenshaw Design Firm, Trautmann added. The house sits within the Locust Valley School District, according to property records.

Trautmann originally listed the property at $15.5 million in the summer of 2024, but then took the property off the market and sold it exclusively in the spring.

Kathe Dodd, an agent at Daniel Gale Sotheby's International Realty who represented the buyer in the deal, called the home "one of the finest properties in Locust Valley."

2: $11 million: 63 Lake Rd., Plandome Manor

This new shingle-style home abutting the Manhasset Bay waterfront closed for $11 million on Dec.17. It's the first of three homes by the same builder to sell on the quiet Lake Road stretch.

Tim O'Sullivan, president of Whitestone-based O'Sullivan Builders & Developers Inc., built this five-bedroom property and two neighboring homes, all designed by Greenwich-based architect Douglas VanderHorn, O'Sullivan said.

It includes a porch on the front, back and side of the house, an 18-by-38-foot saltwater pool and outdoor kitchen, plus permits to install a 315-foot dock, said Patricia Gahan Moroney, an agent with Daniel Gale Sotheby's International Realty who represented O'Sullivan in the deal. It has five full bathrooms and two half bathrooms, O'Sullivan added.

"It's a great space for entertaining," Moroney said. "You have all the amenities of living on the water, but then you also have access to Manhattan and everything that the Manhasset community offers."

The property was originally listed at $12.2 million in the spring of 2024, Moroney said. She added that the home's waterfront access and detailed interiors, including a stair tower topped by a cupola, helped draw the buyer's interest.

O'Sullivan, who has built other multihome projects, said he worked closely with his architect and interior designer Elizabeth Blaney, of Maidstone Lane Visions, to make the inside feel unique.

"We chose every single inch of the place," O'Sullivan said. "We made everything special — every knob, every molding, every paint color — we tried to make everything a work of art."

O'Sullivan finished building the home about a week before it sold to make sure that the new owner and their family could move in before the holidays. He plans to list one of the properties, 71 Lake Rd., on the market next year.

3: $7.95 million: 1263 Pine Valley Rd., Upper Brookville

An Upper Brookville estate closed for $7.95 million in July. The taxes were listed as $65,935.

Built in 2017, the property features seven bedrooms and eight bathrooms. It first hit the market in October 2024, said listing agent Lisa Fasano, of Compass, and sold for its full list price.

"When you pull in, you feel like you went to northern California, or you just slid right into Colorado," Fasano said. "That was the feel of the house: The pines and the backdrop of the property, with the facade and the decorum of the house, just had this different feeling, this different vibe, and it carried right through the front door."

During the selling process, "we had two contracts out, and the third time was a charm, so we did have quite a bit of visibility on the house," Fasano said. It was temporarily taken off the market during the slowdown of the holiday season last year, and Fasano "kept it as a private listing within Compass," she said, before a colleague in her office helped bring in the buyer.

The house, called Residenza Di Serenita, spans about 8,000 square feet and sits on a little more than 2 acres, the agent said. It is on Pine Valley Road in the Locust Valley Central School District.

The property last sold in 2017 for approximately $5.165 million, property records show. Some standout features include a pizza oven in the kitchen, a restored, 100-year-old chandelier overlooking a two-level marble foyer, a primary suite with its own fireplace and terrace and a finished basement, which includes a gym and steam shower.

The backyard is outfitted with an outdoor kitchen, fire pit, pool and spa, along with a pool house that contains a full bathroom, plus air conditioning and heating systems, Fasano said.

The closing was bittersweet: "I do miss the listing," Fasano said. "I loved showing the property and I loved going there."

She added, "This house was truly one of a kind."

4: $7.85 million: 108 Piping Rock Rd.,  Matinecoc k

This Colonial-style, newer home sold for $7.85 million in June.

The seven-bedroom house holds eight bathrooms and three half-bathrooms, plus a wine cellar, full gym and a pool and pool house at the end of a long driveway in tree-covered Matinecoc k , said Daniel Gale Sotheby's International Realty's Bancroft, who represented the buyer and seller.

The previous owners built the house in 2017 to look like a classic North Shore estate, using modern finishings, including a La Cornue luxury stove, Bancroft said. The fact that the property was so new was a major draw for the buyer.

"There aren't many houses on the North Shore of Long Island that are very new but look like a North Shore old estate-style home," Bancroft said. "It was lucky for the buyer to be able to move into something that is so new and fabulous."

Property taxes were recorded at $99,803, according to property records.

Bancroft originally listed the property at $8.5 million in June 2024. The most important part of the deal was timing, Bancroft said, because she also had to find a new home for the seller of 108 Piping Rock Rd., and sell the home of the Piping Rock Road property's buyer.

Despite the complex nature of arranging three consecutive home sales, Bancroft said the $7.85 million purchase was fairly smooth.

"It was a really friendly, lovely transaction," Bancroft said. "The new family was really excited."

5: $7.65 million: 13 Locust Cove Lane, Kings Point

This single-story home on Long Island Sound sold for $7.65 million in January.

The ranch-style house, built in 1949, sits on 1.45 acres of beachfront property within the Great Neck School District, according to property records. It holds four bedrooms, three bathrooms, one half-bathroom and comes with a dock, according to a listing of the property.

The main draw for the buyer was the lot itself, and its views of the Manhattan skyline, said Soheila Sharf, owner of her eponymous real estate firm, Soheila Sharf Realty, who handled the deal for both the buyer and seller.

"At night, it's beautiful. You can see all the lights of the bridges, and the lights of the skyline of Manhattan," Sharf said. "It's the most beautiful view when you see the sunset."

The property was sold at an estate sale, Sharf said, and its new owner plans to build a new home on the lot. It was originally listed for $8.5 million, according to a previous listing of the property.
