Description
Exceptional Carroll Gardens Investment with Future Upside Nestled in the heart of highly desirable Carroll Gardens, this beautifully renovated three-family townhouse presents an exceptional opportunity for investors, owner-occupants, or 1031 exchange buyers seeking strong rental income, long-term appreciation, and outstanding flexibility. The property will be delivered vacant, providing the rare opportunity to lease all three apartments at current market rents, occupy one or more units, or immediately begin renovations or a custom conversion project. The property features three spacious two-bedroom residences, each thoughtfully renovated with modern kitchens, updated full bathrooms, sun-filled living and dining areas, rich hardwood flooring, and exposed brick accents that perfectly blend classic Brooklyn character with contemporary style. The desirable garden duplex offers an in-unit washer and dryer, exclusive access to a private backyard, and each apartment has its own separate boiler and hot water heater, helping minimize owner expenses while maximizing rental income potential. Beyond its current configuration, the property offers the rare opportunity to convert into a spectacular single-family townhouse, allowing a buyer to create a custom dream home in one of Brooklyn's most coveted neighborhoods. Adding even greater value, the property includes buildable air rights (subject to applicable approvals), providing future expansion potential and enhancing its long-term investment appeal. Located just moments from the renowned restaurants, cafés, boutiques, and specialty shops along Court Street and Smith Street, Carroll Gardens is celebrated for its tree-lined streets, historic brownstones, vibrant community, and neighborhood charm. Beautiful parks, highly regarded schools, and the nearby F and G subway lines provide convenient access to Manhattan and the surrounding boroughs, making this one of Brooklyn's most sought-after places to live and invest. Whether you're looking to expand your investment portfolio, complete a 1031 exchange, create your dream single-family residence, or capitalize on future development potential, this exceptional property offers a rare combination of flexibility, location, and long-term value.

Broker Commission Disclosure: Broker commissions are not set by law and are fully negotiable.
How working with a buyer's agent works: I work for you, not the seller. Before I show you anything, New York brokerage rules ask us to put that in writing: an agreement and a disclosure that say I work for you and negotiate on your behalf. The agreement is non-exclusive: you can work with other agents, it runs for a short fixed term we agree on, and you can end it with a note. You may attend open houses independently without an agreement. Read how it works
