LOCATION, LOCATION, LOCATION. A unique property on one of the most desirable streets in Princeton. Located within a block of Nassau Street and a stone's throw from Princeton University, the property features a duplex (currently listed at the township as one unit since 2011) and an unattached unit that fronts on William Street. The layout of the duplex since 2011 has remained as two individual units with an interconnecting door. One side of the duplex features 2 bedrooms and 1 bath and the other side has 1 bedroom/1 bath featuring an upgraded kitchen and newer flooring on the first. A variance would be needed to reinstate the official duplex status of this building. Across the courtyard is a stand alone structure on the same lot with address of 52 William Street. It features a legal 2 bedroom/1 bath unit and includes the driveway for off-street parking for the property. An investor or developer's dream or possible conversion of 20-22 Charlton!
