Overview of 24 Eighth Avenue

24 Eighth Avenue is a converted 25-foot-wide mansion located in Park Slope, Brooklyn, overlooking the historic Montauk Club. The building has been transformed into an intimate eight-unit residential property while maintaining its pre-war architectural character. The structure features period details including high ceilings, decorative mantels, and bay windows with original shutters.

The building's units have undergone modern renovations while preserving historical elements such as refinished hardwood floors and detailed wood trim with decorative accents. The property maintains strong financials with a low underlying mortgage and healthy reserve fund.

Situated just off Grand Army Plaza, the building offers convenient access to multiple transit options including the 2/3/4 trains and the Q/B lines at 7th Avenue. The location provides easy access to Park Slope's commercial district.

The property benefits from its proximity to several cultural landmarks including Prospect Park, the Brooklyn Public Library, Brooklyn Botanic Garden, and the Brooklyn Museum. The Grand Army Plaza Greenmarket, a popular weekend farmers market, is within walking distance.

Sales History

Price/Room (Est)

Why are we displaying the estimated price per room?

For some co-ops, instead of price per square foot, we use an estimate of the number of rooms for each sold apartment to chart price changes over time. This is because many co-op listings do not include square footage information, and this makes it challenging to calculate accurate square-foot averages.

By displaying the price per estimated room count, we are able to provide a more reliable and consistent metric for comparing sales in the building. While we hope that this gives you a clearer sense of price trends in the building, all data should be independently verified. All data provided are only estimates and should not be used to make any purchase or sale decision.
