Description
This Gorgeous four-story brownstone sits on one of the most beautiful treelined Park Slope blocks, 668 10th Street presents prospective purchasers with a vast array of options. A legal three family can be delivered fully vacant and can be used as an investment property or it can be easily converted to a single- or two-family home. Or the new owner can live in the spectacular owner's duplex while continuing to rent the remaining units.
Containing four floors plus a full basement, the building is currently setup as a newly renovated owner's duplex on the garden and parlor floors containing two bedrooms and two bathrooms. On the 3rd and the 4th floor there are 2- two-bedroom floor-through apartments.
Perfectly located on 10th street between 8th avenue and Prospect Park West, the F/G/R subways are less than a block away, shopping and dining options abound, and Prospect Park is just steps from the home. With its prime location and a Park Slope market that remains vibrant, 668 10th street presents an excellent investment opportunity or the chance to create your dream home with or without rental income.
