A town house known to be New York City’s skinniest has been sold for $2.1 million.

The red, 9 ½ foot-wide, 42 foot-long brick building in Greenwich Village was built in 1873 on land used as an alley between homes. The said town house was first listed last August for $2.7 million. The two-bedroom, two-bath home was sold for $1.6 million last 2000.

A plaque on the narrow Bedford Street home notes poet Edna St. Vincent Millay once lived there; so did anthropologist Margaret Mead.

The newly sold building was listed on real estate Web sites Wednesday as a rental available for $10,000 a month. An e-mail seeking comment from the listed rental agent Wednesday was not immediately returned.
