When 423 Clinton Avenue was a House of the Day last October, we called its asking price of $1,800,000 a “bit of a stretch.” It’s now looking like the price was more than a bit of a stretch: The four-story brownstone closed for just $990,000 on March 25, 2009. That’s quite a discount, but not a great surprise given that the house was in need of quite a bit of work. Still, the original details could make it quite a catch for an intrepid restorer at this price. GMAP
