View this charming Classic 6 home located in 505 West End Avenue, a well-run boutique cooperative on the corner of 84th Street in the sweet spot of the Upper West Side. This is the first resale of Apartment 4D which has been lived in and enjoyed by the same family for many years. Rarely available, the D line has great entertaining space. The entry foyer can double as an office and leads to the formal dining room and living room which are separated by glass french doors. The apartment is at the back of the building and therefore it is peaceful with no street noise. The two corner bedrooms are both bathed in western light in the late afternoon. The layout of this Classic 6 lends itself to various uses for the main rooms. If you want a 3rd bedroom there are a number of ways to accomplish this: flip the kitchen and the staff room to make a 3rd bedroom from the current kitchen area or enlarge the staff room by adding the pantry hallway and a foot from the formal dining room, or create a bedroom from the current living room. Please look at the added architectural plans to see various possibilities of changing the layout to suit your needs. (These plans were created and drawn by an architect but have not been presented to the building for approval). You will note that one of the plans has added an additional bathroom. Built circa 1922, this apartment has high ceilings, classic moldings, and original oak hardwood floors throughout. There are two full windowed baths; one with a tub in the hallway bath easily accessed by either bedroom and one with a stall shower in the staff/office room. The kitchen is also windowed and has an original hutch which is charming but in need of removal of years of paint. The kitchen has many possibilities for upgrading and changing the configuration. Other units in the D line have been inventive and designed beautiful unique kitchens in the space. The cooperative has a full-time doorman and a live in super. Amenities include a gym, media room, laundry room and a very special landscaped roof deck with spectacular sky, water and city views. The building is pet friendly, allows washer/dryers and CAC with board approval. Location is ideal with close proximity to both Central and Riverside Parks, local transportation and a wide choice of eating and shopping venues. There is an assessment of $270.23 per month through 10/27. ## Property Details - **Property Type**: Co-op - **Beds**: 2 - **Baths**: 2 - **Rooms**: 6 - **Stories**: 14 - **Year Built**: 1922 - **Common Charges**: $3,693 / Monthly - **Listed On**: Sep 19, 2025 - **Days on Market**: 359 Days ### Residence Features - Building Other - Building Roof Deck ## Sales Evidence ### Recent closed sales 7 apartments at 505 West END Avenue have recorded sales since September 2021, the most recent for $2,150,000 in August 2026.

Those are excluded from the benchmark below. ### How this price compares The median closed price for comparable co-op two-bedroom sales in Upper West Side is $1,400,000, based on 273 sales between September 2024 and July 2026. This home is asking exactly that figure. The middle half of those sales closed between $1,155,000 and $1,800,018. - **Median closed price**: $1,400,000 - **Middle half**: $1,155,000 – $1,800,018 - **Based on**: 273 co-op two-bedroom sales in Upper West Side - **Period**: September 2024 – July 2026 Square footage is recorded for only 61 of these 273 sales (22%), 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. Across the 251 of these sales with a published asking price, the median closed at 97.5% of what it originally asked. 66% of them closed below the original ask. 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 West Side instead. ### How these sales were negotiated - **Sold vs original ask**: 97.5% of the original ask - **Closed below ask**: 66% of 251 sales - **Listed → in contract**: 72 days (about 10 weeks) - **In contract → closed**: 87 days (about 12 weeks) Across the 251 of these sales with a published asking price, the median closed at 97.5% of what it originally asked. 66% of them closed below the original ask. Half of these homes were in contract within 72 days (about 10 weeks) of coming to market, based on the 261 with a recorded listing date. Once a deal was agreed, closing took a further 87 days (about 12 weeks), based on the 259 with both dates recorded. A co-op board package and its interview account for much of that. These are two separate periods measured on different clocks — time to find a buyer, and time from agreed deal to closing. They are medians of different sets of sales and do not add together into a single "days on market" figure. Based on 273 co-op two-bedroom sales in Upper West Side, September 2024 – July 2026. Each figure counts only the sales that recorded the dates it needs, which is why the denominators differ. ### Price trend Median sold price for co-op two-bedroom sales in Upper West Side, 2016 to 2026. The series is held to one bedroom count and one ownership type for the same reason: an unfiltered median tracks which apartments sold, not what they were worth. | Year | Median sold price | Sales | | --- | --- | --- | | 2016 | $1,400,000 | 21 | | 2017 | $1,525,000 | 134 | | 2018 | $1,475,000 | 144 | | 2019 | $1,472,500 | 144 | | 2020 | $1,351,200 | 78 | | 2021 | $1,350,000 | 222 | | 2022 | $1,500,000 | 195 | | 2023 | $1,395,000 | 142 | | 2024 | $1,446,500 | 144 | | 2025 | $1,390,000 | 151 | | 2026 | $1,420,000 | 81 | This building does not have enough sales with a recorded floor area to chart its own price per square foot, which is usual for a co-op. The series above follows comparable homes across Upper West Side instead. Sale prices are the consideration recorded with the City in ACRIS, and each sale is dated by the day the City recorded it. A closing date reported to the MLS typically falls one to two weeks earlier. Recorded sales describe what has already happened and are not an appraisal, a valuation, or an estimate of what this home will sell for.
