About This Home

91 East 31st Street Flatbush, Brooklyn Development opportunity with clear upside in a transit-driven Flatbush location. CASH OFFERS ONLY -Situated on an 18' x 100' lot within an R6 zoning district, this two-family property offers a straightforward path to expansion or full repositioning.The existing structure spans approximately 2,160 square feet and is configured as a two-family with an English basement, allowing for flexible layouts and multiple end-use scenarios. Whether delivered as a renovated multi-unit, owner-user with income, or expanded asset, the current configuration provides a usable base while plans are developed.The key value lies in the additional buildable square footage. With a maximum allowable build of approximately 3,960 square feet, there is roughly 1,800 square feet of unused FAR-creating a clear opportunity for vertical expansion or reconfiguration to maximize returns.Located in an Opportunity Zone and within close proximity to the 2/5 subway lines, the property benefits from strong rental fundamentals and long-term appreciation drivers.This is a clean, scalable project for developers seeking a manageable footprint with meaningful upside in a steadily growing Brooklyn submarket.
