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.

Map
Upper West Side
Overview of Upper West Side
The Upper West Side (UWS) is the intellectual and cultural counterpoint to the East Side. Sandwiched between Central Park and Riverside Park, it is known for its brownstones, protected historic districts, and artistic legacy. For buyers seeking Upper West Side Manhattan real estate, it offers a relaxed, leafy, and quintessentially "New York" vibe. Living in the Upper West Side feels like living in a movie. The streets are wide and lined with trees. As a beloved Manhattan NYC neighborhood, it attracts writers, actors, and families who value space, parks, and Zabar's.Real Estate & Housing Market
The market for homes for sale in the Upper West Side is robust. It is famous for its pre-war co-ops along Central Park West and Riverside Drive, and its miles of brownstone blocks in between. Newer condos have risen in the low 60s and along Columbus Avenue. It is a high-demand market because the housing stock is beautiful and protected. You can't build skyscrapers on the brownstone side streets, preserving the light and character.Lifestyle & Community
The lifestyle on the UWS is casual and community-focused. Neighbors stop to chat at the Sunday landscaped market or while walking dogs in Riverside Park. It feels less formal than the East Side. Cultural institutions like Lincoln Center and the Museum of Natural History anchor the community, infusing it with art and science.Transportation & Accessibility
The Upper West Side is served by the 1/2/3 and B/C trains. The express 2/3 makes getting to Times Square or Wall Street incredibly fast. The West Side Highway provides easy car access for escapes to the Catskills or Jersey.Parks, Schools & Amenities
You are never more than two blocks from a park. Riverside Park offers sunsets over the Hudson, while Central Park offers the Great Lawn and the Reservoir. Amenities are iconic: Zabar's, Fairway, Barney Greengrass. The food culture here is legendary. Schools are excellent, contributing to its reputation as a family haven.Who This Neighborhood Is Best For
The Upper West Side is best for families, dog owners, and creatives who want a beautiful, green, and relaxed neighborhood with deep cultural roots.
