The co-op permits the residential conversion, giving a buyer the opportunity to work with an architect and contractor to create a home tailored to their needs. Alternate floor plans illustrate two possible two-bedrooms layout. The bathroom has been virtually staged with a bathtub. What makes the opportunity particularly compelling is what already exists: a corner position, southern exposure, oversized casement windows and excellent natural light. The first floor is elevated above street level, while a dedicated private entrance from the street creates a true sense of arrival and provides a practical transition space for bikes, strollers and everyday storage. The existing footprint lends itself to a generously proportioned two-bedroom home with substantial living and dining space. Deep closets throughout provide unusually good storage, and the current configuration gives a buyer flexibility to rethink the layout rather than renovate around someone else's choices. Financing options are available and we can connect interested purchasers with a lender experienced in renovation loans for co-op properties. Built in 1927 and designed by Sugarman & Berger, the architects behind One Fifth Avenue, The President is a full-service prewar co-op with a 24-hour doorman, live-in superintendent, laundry room and bike storage. The building is pet-friendly and retains many of its original prewar details. The location is quintessential North Park Slope. Prospect Park and Grand Army Plaza are just blocks away, along with the Saturday Greenmarket, neighborhood restaurants, shops and cafés. Transportation is exceptionally convenient, with the 2/3 trains at Grand Army Plaza and the B/Q at 7th Avenue nearby. The address is zoned for P.S. 321. This is not a move-in-ready apartment unless you are a physician using as a medical office. It is the opportunity to create one, in a full-service prewar building just one block from Prospect Park. Buyer should independently verify all plans, approvals, conversion requirements and permitted use with their architect, attorney and other appropriate professionals. ## Property Details - **Property Type**: Co-op - **Beds**: 2 - **Baths**: 1 - **Rooms**: 4 - **Stories**: 11 - **Year Built**: 1927 - **Common Charges**: $2,527 / Monthly - **Listed On**: Sep 15, 2026 - **Days on Market**: 2 Days ### Residence Features - Building Other - Washer Dryer Allowed ## Estimated Monthly Payment **$6,825 / month**, assuming a 20% down payment ($170,000), a 6.5% interest rate and a 30-year term.

Those are excluded from the benchmark below. ### How this price compares - **This home**: $850,000 - **Median sold price**: $1,100,000 - **Difference**: -$250,000 (-22.7%) - **Comparable sales**: 3 - **Sales from**: November 2022 – November 2025 - **Middle half of those sales**: $992,500 – $1,262,500 Based on two-bedroom sales at The President. Square footage is recorded for only 0 of these 3 sales (0%), so no price per square foot is shown for this group.

They are medians of different sets of sales and do not add together into a single "days on market" figure. ### Price trend Median sale price, co-op two-bedroom sales in Park Slope | Year | Median sold price | Sales | | --- | --- | --- | | 2017 | $1,020,000 | 15 | | 2018 | $954,635 | 14 | | 2019 | $1,087,000 | 16 | | 2020 | $875,000 | 15 | | 2021 | $955,000 | 39 | | 2022 | $1,192,500 | 30 | | 2023 | $1,035,000 | 19 | | 2024 | $1,071,000 | 17 | | 2025 | $1,225,000 | 10 | | 2026 YTD | $1,155,000 | 12 | Based on recorded co-op two-bedroom sales in Park Slope. 2026 is year-to-date. Sales data through July 2026. 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.
