Introducing 67-69 Martense Street, an exceptional opportunity for investors, developers, and primary users alike in the heart of Brooklyn’s vibrant Flatbush section. This massive, fully detached two-family residence sits on an expansive 29.92 ft x 139.58 ft lot, totaling 4,176 square feet. The property currently features a substantial 22x55 building footprint across 2,660 square feet of living space, but its true allure lies in the future. Zoned R7a with a 4.0 Floor Area Ratio (FAR), this site offers a remarkable 16,704 buildable square feet, providing a premier canvas for a significant residential development project in one of the borough's most sought-after growth corridors.

The existing residence is thoughtfully configured with two spacious, sun-drenched apartments. Each unit provides a classic, airy layout consisting of three generous bedrooms, a formal living room, a separate dining room, a full bathroom, and a windowed eat-in kitchen. The versatility continues in the semi-finished basement (with separate entrance), which houses a dedicated laundry room and an expansive recreation space perfect for a home office, gym, or additional storage. Whether you choose to collect premium rental income while planning your development or reside in one unit while the other pays the mortgage, the bones of this detached home offer unparalleled flexibility.

Located in a quintessential Brooklyn neighborhood, this property puts you at the center of a rich cultural and recreational landscape. You are just a short stroll from the lush greenery of Prospect Park, the Brooklyn Botanic Garden, and the historic Kings Theatre. The area is a culinary destination, featuring local favorites like Midwood Flats and a diverse array of international eateries along Flatbush and Church Avenues.

Commuting is effortless with a "Rider’s Paradise" transit rating. You are minutes from the 2 and 5 express trains at Church Avenue and the B and Q lines, offering a swift and reliable connection to Downtown Brooklyn and Manhattan. Additional local transit options include the B35, B41, and B44 bus lines, ensuring every corner of the city is within reach. Do not miss this chance to secure a massive footprint with significant "as-of-right" development upside in the heart of Brooklyn.

Please note that this is an Estate Sale and the final closing is subject to the issuance of Letters from the Surrogate’s Court. All prospective buyers and real estate agents are strictly advised to perform their own independent due diligence regarding square footage, lot dimensions, zoning requirements, and any potential development or "as-of-right" buildable square footage.
