    Overview

    This for-sale duplex is configured as a 6-over-6, with a total property size of 1,872 square feet on a 0.06-acre lot. The property was renovated approximately two years ago. The second floor is currently rented, while the first floor is vacant, giving the next owner flexibility to either continue operating as an income property or convert the vacancy to their own use.

    Located at 51 Cassidy Place on Staten Island in Richmond County, the building sits within zoning designated R3X. With one unit occupied and the other available, the property’s current tenancy can be a practical consideration for buyers looking to assume operations with immediate income from the rented level.

    For investors, the existing second-floor tenancy provides an in-place rental component, while the vacant first floor may allow for occupancy planning upon acquisition. For owner-occupants, the split arrangement can support living on one floor while managing the other as a rental. For more details on current terms and the property’s layout, please contact us.
