## Property Overview

South Slope Rowhouse with Outdoor Space, Light, and Upside

417A 18th Street is a South Slope rowhouse with private outdoor space, low carrying costs, open southern light, and room to improve over time.

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.

Based on house sales in Park Slope with the required listing and closing data. Sample sizes vary by metric.

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.

Sales data through October 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.

The City has not published the official FY2026/27 and FY2025/26 tax rates yet. 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.
