How Many Packs of Gum Does It Take . . .

How many packs of gum does it take to pay off a $350,000 mortgage? The Post investigates:

For $350,000, you can own a building with 50 square feet of usable space on a 102-square-foot commercial lot on Seventh Avenue South in the West Village.

. . .

That $350,000 will buy you 10 feet of frontage on the busy avenue, explains real-estate broker Rod Kritsberg of A&I Broadway Realty.

That’s perfect for a newsstand, cab stand, crepe window or fast-food shop, says Kritsberg, who is advertising the property on craigslist.org.

Its location — at 30 Seventh Ave. S., between Leroy and Morton streets — “is right in the heart of Greenwich Village,” he said.

“It’s a vibrant area, on a street where you get a lot of foot traffic, especially at night,” he noted. “There’s no place that sells water, cigarettes and gum for several blocks.”
