A single unit in 1372 Dean now costs what the entire building cost in 2013.

In Sept 2013, this lovely Brownstone on Dean in Crown Heights North sold for $1.3M.

Since then, the building has been subdivided and renovated, and a SINGLE UNIT in it is now asking that price.

How many units are there now?

Four.

...I think this one is among the bigger, more expensive units.

Unit D is now listed as a rental:
