Description
This lovely Garden Duplex sits at the border of South Slope and bustling Greenwood. Though it is a one bedroom with rec room, it is currently being used as a large two bed 1.5 bathroom home. The very large "Rec Space" is currently configured as an extra large master with en suite but the possibilities are endless. Central Heat and Air Conditioning, Modern Appliances and a beautifully landscaped bi-level Back Yard make this property a must see. Low caring costs, a tax abatement in place until 2031, and increasing local development at the heart of two bustling neighborhoods make this is a fabulous starter home or perfect investment property. There is laundry in the building as well as a large extra storage unit. Near Industry City, Sunset Park, Subways, Restaurants, Cafes and Shopping.
