571 40th Street is a classic brick home on one of Sunset Park's prettiest tree-lined blocks just 1 block from the park. A three-family currently configured as a two-family, it offers five bedrooms and three baths across an owner's duplex and a top-floor rental, with flexibility for how a buyer lives now and later: live in the duplex and let the rental help carry the mortgage, or restore the third unit for additional income. The duplex begins on the garden level, where a long living and dining room leads back to an eat-in kitchen with laundry, a full bath, and a mudroom opening to the deep backyard. A paved patio leaves plenty of room to grill and dine outdoors, with planted beds for gardening. On the parlor floor above, 10-foot ceilings and original moldings frame three bedrooms, a walk-in closet, and an original tiled bath. The top floor is a two-bedroom, one-bath apartment with its own kitchen, a living and dining room, and a den that works well as a home office. A full cellar provides abundant storage. Just a block away is the neighborhood's namesake park, one of Brooklyn's highest points, with sweeping views of the harbor, the Statue of Liberty, and the Manhattan skyline, along with an Olympic-size pool, a recreation center, a soccer field, and a spray playground. Beyond the park, Sunset Park is one of Brooklyn's most diverse neighborhoods, with a remarkable range of restaurants and markets along Fifth and Eighth Avenues and Industry City's shops, food hall, and waterfront a short walk west. The D, N, and R trains at 36th Street are minutes away.
