The Private Brokerage Advantage
As an independent luxury buyer representative, Régis shares 50% of the buyer-side commission he actually receives on your purchase. Eligible buyers receive that Buyer Commission Share directly at closing to offset closing costs, down payments, or renovations. The figures beside this are illustrative, based on a 3% buyer-broker commission; your share follows the commission offered on the transaction.

Square footage is recorded for only 53 of these 180 sales (29%), so no price per square foot is shown for this group. Co-op sales rarely carry a floor area, and a figure drawn from a handful of them would not describe the rest.
This building has not had enough comparable sales of its own in the period to support a median, so the benchmark is drawn from Upper East Side instead.

Map
Upper East Side
Overview of Upper East Side
The Upper East Side (UES) is the epitome of classic New York wealth and culture. Stretching from Central Park to the East River, it is home to Museum Mile, Madison Avenue fashion, and some of the most prestigious addresses in the world. For buyers seeking Upper East Side Manhattan real estate, it offers a lifestyle of polished elegance and safety. Living in the Upper East Side ranges from the ultra-luxury of Fifth Avenue to the bustling, younger energy of Second Avenue. As a premier Manhattan NYC neighborhood, it remains the gold standard for residential stability and top-tier schools.Real Estate & Housing Market
The market for homes for sale in the Upper East Side is surprisingly diverse. While famous for $20 million townhouses and co-ops, the eastern avenues (Yorkville) offer excellent value for studios and one-bedrooms. It is valid to say it has two markets: the "Gold Coast" west of Lexington (historic, expensive, co-op heavy) and the area east of Lexington (more condos, more rentals, more affordable).Lifestyle & Community
The lifestyle on the UES is refined. Residents spend weekends at the Met or the Guggenheim, jogging in Central Park, and dining at established bistros. It is less trendy than downtown but more livable. The community is generational. You will see grandmothers and toddlers who both grew up in the neighborhood. It feels established, clean, and manicured.Transportation & Accessibility
The Upper East Side was transformed by the Second Avenue Subway (Q train), which relieved pressure on the 4/5/6 line. Now, the area feels incredibly connected to Midtown and downtown. The crosstown buses through the park (at 65th, 79th, 86th, 96th) are vital lifelines to the West Side.Parks, Schools & Amenities
Central Park is the neighborhood's front yard. Carl Schurz Park on the East River is a hidden gem with a dog run and promenade. Amenities are world-class. The area has the highest concentration of private schools in the city (Dalton, Spence, Chapin) and top hospitals (Lenox Hill, Mt Sinai), making it a magnet for families and professionals.Who This Neighborhood Is Best For
The Upper East Side is best for families, culture lovers, and anyone who wants a classic, safe, and green New York City experience.
