According to this online listing, long-vacant 1600 Eighth Street, Northwest (MLS No. DC7146640) sold on October 31, 2009. The stated closing price is $415,000, $35,000 under asking. The new owner's name does not yet appear in the online Real Property Database. Here's to hoping we see a great renovation of this gorgeous, highly visible corner property soon!
Caddy-cornered 1543 Eighth Street, Northwest is still for sale (check out its listing here). I have my fingers crossed that someone will purchase 1543 soon, too, and thereby bring this entire intersection into a new era of viability and beauty!
