## Property Overview

Ready to be re-imagined and renovated! Welcome to this handsome circa 1901 brick single-family townhouse on a coveted tree-lined block in the heart of Park Slope. Rich with original character and filled with natural light, this three-story home plus cellar presents a rare opportunity to restore and reimagine a classic Brooklyn townhouse with incredible scale, warmth, and preserved architectural detail. Beyond the stoop, the home unfolds with gracious proportions, soaring ceilings, original wood floors throughout, decorative fireplaces, pocket doors, French doors, intricate moldings, and beautifully preserved millwork. Historic details remain intact across all levels, offering the perfect canvas for a thoughtful renovation or gradual restoration. The garden level features a well proportioned living space and oversized eat-in kitchen with terra-cotta tile floors, tin ceilings, abundant cabinetry, and a bright sunroom overlooking the expansive backyard. A charming full bath and direct garden access complete the level, creating excellent potential for indoor-outdoor living and entertaining. At the rear of the building, a deep private backyard provides an exceptional outdoor retreat rarely found in Park Slope - ideal for gardening, entertaining, or creating a truly spectacular landscaped oasis. The parlor floor, most recently used as two bedrooms, also offers an option for dramatic living and entertaining spaces with elegant decorative fireplaces, oversized windows, and original parquet flooring bathed in natural light. Upstairs is a generously scaled bedroom plus two smaller flexible rooms which could be combined to make a second large bedroom on this floor. Also on the top floor is a generously sized bathroom with a skylight. While the property would benefit from updates and restoration, the home's original craftsmanship, layout, and preserved detail make this a compelling opportunity for buyers seeking authenticity and long-term value. Full of charm, scale, and potential, this is a chance to create a truly special townhouse residence in one of Brooklyn's most sought-after neighborhoods.
 637 Baltic Street is unique and desirable with its additional unused buildable square feet. Take advantage of the opportunity to expand with 1,181 SF of additional FAR (buildable square feet)

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 September 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 3009370065. 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.
