Before you visit the sales gallery, understand the broker registration rule. In many buildings the sponsor will only compensate a buyer’s broker who accompanied you on your first visit or registered you in writing beforehand. The sales team you meet at the door works for the developer, and once you have toured on your own that introduction is very hard to undo.

Prices are the figures recorded with the City, not asking prices. | Unit | Beds | Sq Ft | Sold Price | $/ft² | Sold | Source | | --- | --- | --- | --- | --- | --- | --- | | C4A (Apartment) | 2 | 915 | $1,380,000 | $1,508/ft² | October 14, 2025 | 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 two-bedroom sales in Park Slope is $1,540,000, based on 53 sales between September 2024 and June 2026. This home is asking $2,850,000, $1,310,000 above that median. The middle half of those sales closed between $1,365,000 and $1,695,000. - **Median closed price**: $1,540,000 - **Middle half**: $1,365,000 – $1,695,000 - **Based on**: 53 condo two-bedroom sales in Park Slope - **Period**: September 2024 – June 2026 - **Median $/ft²**: $1,574/ft² Across the 50 of these sales with a published asking price, the median closed at 100% of what it originally asked. 40% 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 Park Slope instead. ### How these sales were negotiated - **Sold vs original ask**: 100% of the original ask - **Closed below ask**: 40% of 50 sales - **Listed → in contract**: 35 days (about 5 weeks) - **In contract → closed**: 69 days (about 10 weeks) Across the 50 of these sales with a published asking price, the median closed at 100% of what it originally asked. 40% of them closed below the original ask. Half of these homes were in contract within 35 days (about 5 weeks) of coming to market, based on the 49 with a recorded listing date. Once a deal was agreed, closing took a further 69 days (about 10 weeks), based on the 49 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 53 condo two-bedroom sales in Park Slope, September 2024 – June 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 two-bedroom sales in Park Slope, 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 | $1,325,000 | 28 | | 2018 | $1,201,250 | 16 | | 2021 | $1,155,000 | 37 | | 2022 | $1,852,500 | 34 | | 2023 | $1,292,500 | 14 | | 2024 | $1,442,500 | 16 | | 2025 | $1,465,000 | 27 | | 2026 | $1,590,000 | 19 | 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 Park Slope 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 that year using the prior year’s rate, so treat it 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 3009861301. 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.

The New York City and New York State transfer taxes are the seller’s in a resale and are passed to the purchaser in most offering plans, and the sponsor’s attorney fee and any working capital contribution sit on top of that. Together they commonly add 2% or more of the purchase price. - [Estimate these costs](https://realestaterebatesnewyork.com/calculators/new-development-closing-cost-calculator) - [What sponsor buyers pay](https://realestaterebatesnewyork.com/new-development-closing-costs-nyc) - [More new developments](https://realestaterebatesnewyork.com/new-developments) ## Park Slope Overview of Park Slope [Explore Park Slope](https://realestaterebatesnewyork.com/neighborhoods/new-york-city/brooklyn/park-slope) · [All Neighborhoods](https://realestaterebatesnewyork.com/neighborhoods) ### Nearby Park Slope - [Prospect Heights real estate for sale](https://realestaterebatesnewyork.com/neighborhoods/new-york-city/brooklyn/prospect-heights) - [Gowanus real estate for sale](https://realestaterebatesnewyork.com/neighborhoods/new-york-city/brooklyn/gowanus) - [South Slope real estate for sale](https://realestaterebatesnewyork.com/neighborhoods/new-york-city/brooklyn/south-slope) - [Prospect Park real estate for sale](https://realestaterebatesnewyork.com/neighborhoods/new-york-city/brooklyn/prospect-park) - [Boerum Hill real estate for sale](https://realestaterebatesnewyork.com/neighborhoods/new-york-city/brooklyn/boerum-hill) - [Carroll Gardens real estate for sale](https://realestaterebatesnewyork.com/neighborhoods/new-york-city/brooklyn/carroll-gardens) ## Related Links - [347 6th Avenue — building page](https://realestaterebatesnewyork.com/buildings/new-york-city/brooklyn/347-6th-avenue) - [Park Slope neighborhood guide](https://realestaterebatesnewyork.com/neighborhoods/new-york-city/brooklyn/park-slope) - [Estimate your Buyer Commission Share and closing costs](https://realestaterebatesnewyork.com/calculators/buyer-closing-cost-calculator) - [Contact Régis Roumila](https://realestaterebatesnewyork.com/contact) --- > RLS IDX Data display by Real Estate Rebate Team.
