Contact Régis Roumila](https://realestaterebatesnewyork.com/contact) ## Property Overview 24 East 21st Street is a rare opportunity to own a full-floor residence in one of Flatiron's most discreet boutique condominiums. A private elevator opens directly into the grand living and dining room, an impressive 40 by 20 feet with soaring 11-foot beamed ceilings, stained wide-plank oak floors, and natural light from both north and south exposures. A glass, brushed aluminum, and galvanized steel-enclosed gas fireplace anchors the space, while elegant glass doors open onto a private central outdoor atrium with a stunning pergola - a serene focal point at the heart of the home. Enormous picture windows frame the streetscape throughout. The chef's kitchen is appointed with a seamless Bianco Statuario marble island and breakfast bar, custom Italian white lacquer and aluminum cabinetry, a walk-in pantry, and a premium appliance suite including a 27-inch Sub-Zero refrigerator, 27-inch Sub-Zero freezer, 48-bottle wine cooler, six-burner Viking convection range with vented hood and built-in microwave, and Bosch dishwasher. The primary suite is a true retreat, featuring an enormous walk-in closet complemented by an additional bank of in-room closets, blackout shades, and a spa-caliber en suite bathroom with a soaking tub, separate stall shower, and double vanity. A dedicated media room with a 100-inch screen-easily convertible to an additional bedroom-a private home office with an en suite bath, and two additional well-proportioned bedrooms complete the layout with exceptional versatility. There are also 4.5 bathrooms throughout the home. Additional features include two-zone central air conditioning, a commercial-grade washer and dryer, overhead lighting, a generous closet and storage space, and a Crestron smart home system. Infinity Flats is a boutique condominium comprised of just eight full-floor residences, offering a full-time cyber doorman, exceptional privacy, and remarkably low carrying costs. With coveted north and south exposures, impressive scale, complete floor-through privacy, and undeniable downtown cachet, residences of this caliber are rarely available at this price per square foot. ## Property Details - **Property Type**: Condominium - **Beds**: 3 - **Total Baths**: 5 - **Rooms**: 8 - **Sqft**: 4,073 sqft - **Stories**: 9 - **Year Built**: 1935 - **Price per Sqft**: $1,289 - **Common Charges**: $3,107 / Monthly - **Listed On**: Jun 2, 2026 - **Days on Market**: 102 Days ### Residence Features - Washer Dryer Allowed ## Sales Evidence ### Recent closed sales 2 apartments at 24 East 21st Street have recorded sales since September 2021, the most recent for $5,250,000 in August 2026. Prices are the figures recorded with the City, not asking prices. | Unit | Beds | Sq Ft | Sold Price | $/ft² | Sold | Source | | --- | --- | --- | --- | --- | --- | --- | | 2 (Apartment) | 3 | 4,073 | $5,250,000 | $1,289/ft² | August 3, 2026 | MLS | | PH (Apartment) | 4 | 4,109 | $6,995,000 | $1,702/ft² | May 26, 2026 | City record · MLS | Every row is a recorded transaction, including ancillary spaces such as storage and staff rooms where they were sold separately. Those are excluded from the benchmark below. ### How this price compares The median closed price for comparable condo three-bedroom sales in Flatiron is $4,225,000, based on 28 sales between September 2024 and July 2026. This home is asking $5,250,000, $1,025,000 above that median. The middle half of those sales closed between $3,562,500 and $5,193,750. - **Median closed price**: $4,225,000 - **Middle half**: $3,562,500 – $5,193,750 - **Based on**: 28 condo three-bedroom sales in Flatiron - **Period**: September 2024 – July 2026 - **Median $/ft²**: $2,047/ft² Across the 26 of these sales with a published asking price, the median closed at 90.5% of what it originally asked. 96% 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 Flatiron instead. ### How these sales were negotiated - **Sold vs original ask**: 90.5% of the original ask - **Closed below ask**: 96% of 26 sales - **Listed → in contract**: 140 days (about 20 weeks) - **In contract → closed**: 52 days (about 7 weeks) Across the 26 of these sales with a published asking price, the median closed at 90.5% of what it originally asked. 96% of them closed below the original ask. Half of these homes were in contract within 140 days (about 20 weeks) of coming to market, based on the 27 with a recorded listing date. Once a deal was agreed, closing took a further 52 days (about 7 weeks), based on the 27 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 28 condo three-bedroom sales in Flatiron, 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 condo and house three-bedroom sales in Flatiron, 2017 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 | | --- | --- | --- | | 2017 | $6,557,466 | 30 | | 2018 | $5,100,000 | 10 | | 2021 | $5,325,000 | 18 | | 2022 | $4,685,000 | 22 | | 2024 | $4,550,000 | 17 | | 2025 | $4,200,000 | 13 | | 2026 | $4,250,000 | 13 | 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 Flatiron 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.

We calculated the tax for those years using the prior year’s rate, so treat them as an estimate rather than a figure the City has adopted. Every rate without the Estimated marker is the published one. Tax Assessment is the assessed value on the City’s roll, and it is the figure other listing sites publish. It is not what the bill is calculated on. New York phases assessment changes in gradually for some tax classes, so the City bills the Billable Value shown beside it, less any exemption the owner holds. It usually trails the assessment, and it can sit above it for a few years after an assessment falls. Figures are the New York City Department of Finance assessment roll for tax lot 1008491502. Assessed and billable values are determined by the City for tax purposes and are not an appraisal or an estimate of market value. Tax classes and rates are set annually and can change.
