Overview of 434 Throop Avenue

434 Throop Avenue is a meticulously renovated classic brownstone in Bedford-Stuyvesant that has been transformed into a two-unit, passive house inspired residence. The extensive renovation includes all new plumbing, electrical, and mechanical systems, a new water main, hybrid electric heat pump water heaters, and remote read meters. Both units feature passive house certified triple pane gas filled windows and advanced filtration and ventilation systems by Zehnder, along with comprehensive smart home technology controlling locks, doorbells, lighting, thermostats, ventilation, smoke and CO detectors, and package management.

Unit 1 is a 2,474 square foot triplex with three bedrooms and three bathrooms, offering nearly 800 square feet of outdoor space including an exclusive backyard and private deck. The cellar level includes a massive recreation room, half bathroom, utility and laundry room, and storage. Unit 2 is a 1,806 square foot triplex with three bedrooms and 2.5 bathrooms, featuring a large private balcony and a private rooftop deck. Both units share similar high-end finishes including 5 inch solid white oak plank hardwood floors, chef's kitchens with Bosch stainless steel appliances and 14 foot islands that seat up to six, custom cabinetry with pull out shelves and quartz waterfall countertops, and primary suites with walk in closets, double vanities, and walk in showers with dual shower heads. All bathrooms feature radiant heated floors, and each unit includes in-unit washers and energy efficient ventless electric heat pump dryers.

The building sits on a tree lined block with Herbert Von King Park and Kosciuszko Pool on the next block, and Prospect Park 1.5 miles away. The location offers access to multiple subway lines including the G, A/C, J/Z, and M trains, along with bus service and CitiBike stations. Investment details indicate Unit 1 recently rented for $8,000 per month while Unit 2 is marketed at $7,500 per month, with projected annual income of $186,000 and annual costs of $21,000.
