Property Description for 414 3rd Street, 3-R/4R

This top floor, Park Slope duplex is an investment opportunity on arguably one of the best blocks in Brooklyn! Situated in center slope, between 5th and 6th Aves, in a charming Prewar limestone walkup are two combined units, 3R and 4R, that create a very spacious duplex. This quiet and bright Southern facing unit, features three bedrooms and two full baths. Renovate the duplex or remodel the two units to individually separate them and turn one over for a profit. This already generous home feels even bigger due to its open, loft-like layout and oversized windows with lovely, lush garden views. Upon entering, one appreciates many beautiful pre-war elements and architectural details that contribute to the beauty and potential of this special home: exposed brick, hardwood floors, high ceilings, a decorative fireplace and a windowed kitchen, to name a few.

This as-is unit also includes two storage units and a convenient laundry facility in the basement. 414 3rd Street is a pet friendly, pre-war walk-up cooperative with only seven units. It is situated just half a block above 5th avenue. Residents can appreciate living on historic 3rd Street, with its tree-lined, boulevard sidewalks directly across from the weekly farmer's market at JJ Byrne park. This boutique co-op is also minutes away from some of the best restaurants in Park Slope (among them the Stone Park Cafe and al di la) and has convenient access to the F, G, and R train lines. There is currently an assessment of $470/mo for various fees related to the sale of these two units.

Park Slope | Brooklyn

Quick Profile

Boasting beautiful tree-lined streets, brownstones and a range of activities for all age groups, Park Slope is consistently ranked as one of New York’s most desirable neighborhoods. Filled with lush parks and greenery, the neighborhood is also known for its rare combination of excellent public schools, award-winning restaurants, nightlife, small independently owned businesses and community gardens.

Situated at the western slope of Prospect Park, the neighborhood is divided into different sections: North Slope, Center Slope and South Slope. Depending on who you ask, of course, the definitions of where these borders end and begin may vary (is the divide between North and Center deemed Union Street, Garfield Place, 1st Street or 3rd Street? The one between Center and South 6th Street, 9th Street, 11th Street or 15th Street?). 

Regardless of what part of the Slope you find yourself on, there’s no shortage of architectural beauty. From row houses to brownstones to mansions, the idyllic setting of the neighborhood is further enhanced by its Romanesque and Renaissance Revival styles. Case in point of this is also two of the area’s most well-known churches, Park Slope United Methodist Church and Saint Augustine Roman Catholic Church. 

Revered for its family-friendly appeal, Park Slope is often regarded as one of the best places to raise a family in New York City. That said, it doesn’t mean that parents don’t know how to have a good time... a slew of bars constantly opening in the neighborhood ranging from the high-end cocktail saloon to the dive (well, by Park Slope standards, anyway).
