Live and Work in a Tribeca Triplex

A bargain-basement price on a new downtown triplex probably means you're buying the basement, but at 53 Murray Street, you're getting the raw sub-basement, too. At $3.25 million for 5,335 square feet, the apartment costs just over half of Tribeca's average, according to StreetEasy. The sub-basement is great for architects, artists, and other tinkerers, with three rooms on the upper floors usable as bedrooms, says Shari Markoff of the Shvo Group. The basement includes a north-facing bedroom that gets decent light (though it faces another building). So if you need only one bed, Markoff suggests, you might festoon the first floor with fanned magazines and potpourri and welcome customers there. "It could make a great spa," she suggests. "Or it could be great for a not-for-profit." If you're in start-up mode, a location near the Fulton Street transit hub and a price you can defend to your investors will help anybody sleep at night. —Alec Appelbaum
