Tuesday, Aug 4, 2026 By CityRealty Staff, CityRealty contributor

From July 27 - August 2, 2026, 188 residential contracts were signed in Manhattan. This figure and the aggregate dollar amount represent a small week-over-week uptick, but still the second smallest deals of 2026 since late February. However, both the number of contracts signed and aggregate dollar volume show year-over-year increases from this same time last year.

Manhattan ultimately reported 873 residential contracts signed in July 2026. While four more signed than the previous July, this figure marks a significant month-over-month decrease. However, it cannot be overlooked that the first half of 2026 (which includes June) was especially robust in spite of geopolitical turmoil, the passing of the pied-a-terre tax at state level, and limited new supply. It must also be noted that summer months are typically slow ones for the residential market, and that likely explains what has happened in 2026.

Homes in beautiful adaptive reuse projects among top deals

175 Fifth Avenue, Flatiron Building, NYC landmark

The Flatiron Building, home of the week's top contract

The week's top five contracts were all located in Downtown neighborhoods, and Residence #18SOUTH in The Flatiron Building had the week's top deal with an asking price of $15.65 million. The half-floor three-bedroom features the Flatiron Building's signature curved windows in the living room and primary bedroom and, like all units in the former office building that housed book publisher St. Martin's Press and later its parent company, Macmillan, just before the pandemic, has been transformed into a luxurious home by Studio Sofield. Move-ins are expected to begin this fall.

The Flatiron Building is a stunning example of adaptive reuse in New York City, and it was one of several that proved popular among luxury buyers last week. Two contracts were signed at 108 Leonard Street, the condo conversion of the New York Life Insurance Company headquarters; these included Residence #12N, a four-bedroom asking nearly $6.5 million in the week's eighth-highest contract. Two contracts were also signed at Waldorf Astoria Residences New York, a newly created collection of condos on the uppermost floors of the famed luxury hotel on Park Avenue.

Sohmer Piano Building penthouse sells for $9M at auction

Last week's top contracts also included the penthouse at The Sohmer Piano Building, which was asking $9 million. While this was good enough for the third-highest deal of the week, it is 64 percent less than the seller, Boston Technology co-founder/philanthropist Greg Carr, initially sought. He initially listed it for $25 million in November 2024; however, when it failed to find a buyer, he marketed it at auction through Concierge Auctions in cooperation with Claire Groome and Lawrence Treglia of Sotheby's International Realty. The auction ended on July 29; the sale has not been recorded by the city, nor has the buyer been revealed.

Public records show that Mr. Carr acquired the penthouse for $7.22 million in 2007. All proceeds from the sale are to go to The Gorongosa Project, which aims to restore Mozambique's Gorongosa National Park and the local economy.

The penthouse was one of two contracts signed in The Sohmer Piano Building last week. It is located directly across from the Flatiron Building at 170 Fifth Avenue, and was designed as a store-and-loft building by Robert Maynicke in 1897. Amidst its conversion to loft condos in 1999, it was named in honor of one of its early tenants, the Sohmer Piano Company, and a two-story cupola dome was reclad in copper and hand-applied 24-karat gold leaf gilding by Bone/Levine Architects. The cupola was incorporated into a private roof deck for the penthouse; and, in a story that ran shortly before bidding began, the New York Post noted that the likes of Lauren Bacall attended fundraising events in the penthouse.

Rowan II triumphs among new construction

Of new construction condos throughout New York City, Astoria condominium Rowan II was one of the week's top performers with four contracts signed, tying for the distinction with Long Island City condominium Radiant. It is located directly north of The Rowan, a boutique condominium that broke its own Astoria sales record in May 2021.

Interiors by Ucean Creations feature chevron oak flooring, kitchens with white marble countertops and integrate Miele appliances, and primary baths with radiant heated floors and floating wood vanities. Occupancy is estimated for early next year, and public availabilities range from a one-bedroom for $695K to a three-bedroom penthouse with private terrace for $2.185 million.

In addition to the Queens condos, new developments throughout New York City reported multiple sponsor deals. These included 108 Leonard Street in Tribeca, Waldorf Astoria Residences New York in Midtown, and Ocean Tower in Sheepshead Bay.
