The old link for 438 N St is no longer active. Walking by 438 N St NW, the place looks fine.
The property was last sold 2013 to an owner claiming the homestead deduction. According to the DC PIVS permits were issued in 2010 and 2011 for work done, which I'll gather was the work that took the property from vacant to occupied.
So moving on, nothing to see here folks.
