Recent practical improvements, including a new upper bathroom, new windows, and a new facade, make the house livable now for a buyer who prefers to settle in before taking on larger work. Others may choose to approach the property more comprehensively from the outset. Either way, the opportunity is flexible: use what works, improve what does not, and shape the house over time according to your needs, taste, and long-term vision. Inside and out, the home has the character associated with older Brooklyn rowhouses: texture, history, and a sense of place. It is not a fully finished designer renovation, but it offers the essential ingredients many buyers look for in a Brooklyn house: outdoor space, natural light, location, and flexibility. The block itself shows a range of approaches to rowhouse renovation, with nearby homes updated in both traditional and more modern styles. With no houses directly across the street and a south-facing facade, the property benefits from a brighter, more open exposure than many rowhouses typically enjoy. The private rear outdoor space adds practical value for gardening, dining, entertaining, play, or a quiet place to step outside. Located in South Slope, 417A 18th Street is near neighborhood restaurants, cafes, shops, transit, Green-Wood Cemetery, and Prospect Park, in a market where available houses remain limited.

Prices are the figures recorded with the City, not asking prices. | Unit | Beds | Sq Ft | Sold Price | $/ft² | Sold | Source | | --- | --- | --- | --- | --- | --- | --- | | Entire property (Duplex) | 6 | 3,672 | $5,300,000 | $1,443/ft² | July 28, 2025 | MLS | | Entire property (Single Family Residence) | 3 | 1,960 | $995,000 | $508/ft² | June 11, 2024 | MLS | ### How this price compares The median closed price for comparable house sales in Park Slope is $3,400,000, based on 56 sales between October 2021 and August 2026. This home is asking $1,795,000, $1,605,000 below that median. The middle half of those sales closed between $2,576,250 and $3,942,500. - **Median closed price**: $3,400,000 - **Middle half**: $2,576,250 – $3,942,500 - **Based on**: 56 house sales in Park Slope - **Period**: October 2021 – August 2026 - **Median $/ft²**: $1,100/ft² Across the 42 of these sales with a published asking price, the median closed at 95.9% of what it originally asked. 60% of them closed below the original ask. A house is not part of a building of comparable apartments, so this benchmark is drawn from house sales across Park Slope. Apartment sales are excluded from it entirely. ### How these sales were negotiated - **Sold vs original ask**: 95.9% of the original ask - **Closed below ask**: 60% of 42 sales - **Listed → in contract**: 47 days (about 7 weeks) - **In contract → closed**: 73 days (about 10 weeks) Across the 42 of these sales with a published asking price, the median closed at 95.9% of what it originally asked. 60% of them closed below the original ask. Half of these homes were in contract within 47 days (about 7 weeks) of coming to market, based on the 55 with a recorded listing date. Once a deal was agreed, closing took a further 73 days (about 10 weeks), based on the 54 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 56 house sales in Park Slope, October 2021 – August 2026. Each figure counts only the sales that recorded the dates it needs, which is why the denominators differ. 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 3008750058. 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.
