What's special

This sale opportunity is a Two (2) family home situated on Rock Avenue in Piscataway NJ. This property features two (2 BR/1Bath) units, a garage, backyard and attic. The first floor is currently rented at $2,495 per month. The second floor is currently vacant and is "move in" ready for potential home buyers. This asset offers several value-add opportunities. The garage is available to be rented for additional income (previously rented for $650 per month). The attic is also a potential value-add asset by converting it into more living space for the second-floor unit. The attic currently has its own separate entrance and is not connected with the second-floor unit at this time. There is potential to convert the second-floor unit into a 3BR/2Bath with the addition of the attic space.
