Tribeca is more known for its sprawling lofts than townhouses, so it's not a huge stretch for the brokerbabble to call this house, located at 17 Harrison Street between Greenwich and Staple streets, "as rare as it gets." In fact, StreetEasy lists just four other move-in ready homes, two of which are obscenely priced. Built in 1869, this Harrison Street house was originally used by butter and egg merchants, and the exterior features a cast iron base, masonry facade, and pressed metal cornice. Inside, it measures 5,700 square feet (plus a 1,400-square-foot basement), split between a lower-level rental and a six-bedroom owner's triplex. There's a solarium, rooftop terrace, and a huge skylight over the central staircase. It was last renovated about 20 years ago, so it might need a few upgrades, but the listing claims "this home is as solid as they come." It's asking $13.5 million.
