To your right is the appropriately named great room, an open-plan living and dining space with beautiful white oak floors and a wall of park-facing windows that provide an ideal backdrop for lounging, dining, or cooking-perfect for either entertaining or a quiet night at home. A large Caesarstone countertop and dining bar connects the kitchen to the larger space, providing social flow and extra seating if need be, while the kitchen itself, of course, is outfitted with a high-end Miele appliance package across the board. There is also an in-unit Miele washer/dryer, adding convenience to classic comfort. Unique to this unit is the solarium, an indoor sun-room with another western exposure-directly facing the lush greenery of Central Park, and in the fall or winter, overlooking the pond. It's a rare space to slow down with your morning coffee, reading or relaxing while savoring the tranquil park views whatever the season. 923 Fifth Avenue is a historic 21-story building with an Art Deco flair and a limestone base that was built in 1950 and converted to a condo in 1983, right in the heart of the landmarked Upper East Side Historic District.

The building is also full-service and amenity-rich, featuring a 24-hour doorman, live-in superintendent, fitness room, central laundry room, bike room, building storage, and on-site parking. Simply put: This residence will not be like any other home you find in your search. Dare to make it yours. ## Property Details - **Property Type**: Condominium - **Beds**: 2 - **Baths**: 2 - **Rooms**: 4 - **Sqft**: 1,190 sqft - **Stories**: 21 - **Year Built**: 1950 - **Price per Sqft**: $2,937 - **Common Charges**: $18,771 / Monthly - **Listed On**: Sep 8, 2026 - **Days on Market**: 1 Days ### Residence Features - Building Other - Washer Hookup - In Unit - Dishwasher - Park/Greenbelt ## Sales Evidence ### Recent closed sales 14 apartments at 923 5th Avenue have recorded sales since September 2021, the most recent for $6,400,000 in April 2026.

Those are excluded from the benchmark below. ### How this price compares The median closed price for comparable two-bedroom sales at 923 5TH Avenue is $4,000,000, based on 7 sales between January 2022 and November 2025. This home is asking $3,495,000, $505,000 below that median. The middle half of those sales closed between $3,212,500 and $5,005,000. - **Median closed price**: $4,000,000 - **Middle half**: $3,212,500 – $5,005,000 - **Based on**: 7 two-bedroom sales at 923 5TH Avenue - **Period**: January 2022 – November 2025 - **Median $/ft²**: $2,946/ft² Across the 5 of these sales with a published asking price, the median closed at 91% of what it originally asked. 80% of them closed below the original ask. ### How these sales were negotiated - **Sold vs original ask**: 91% of the original ask - **Closed below ask**: 80% of 5 sales - **Listed → in contract**: 176 days (about 25 weeks) - **In contract → closed**: 97 days (about 14 weeks) Across the 5 of these sales with a published asking price, the median closed at 91% of what it originally asked. 80% of them closed below the original ask. Half of these homes were in contract within 176 days (about 25 weeks) of coming to market, based on the 6 with a recorded listing date. Once a deal was agreed, closing took a further 97 days (about 14 weeks), based on the 6 with both dates recorded. 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 7 two-bedroom sales at 923 5TH Avenue, January 2022 – November 2025. Each figure counts only the sales that recorded the dates it needs, which is why the denominators differ. ### Price trend Median price per square foot for sales at 923 5TH Avenue, 2017 to 2023. Price per square foot is used rather than sale price so the line follows the market rather than whichever apartments happened to change hands that year. | Year | Median $/ft² | Sales | | --- | --- | --- | | 2017 | $3,558/ft² | 3 (thin) | | 2022 | $2,957/ft² | 4 (thin) | | 2023 | $2,946/ft² | 3 (thin) | Years marked "thin" rest on fewer than 5 sales, where a single unusual apartment moves the median a long way. Read those points as the small samples they are rather than as the market turning. 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.
