It just goes to show you, not even the president is immune to the real-estate slump.

According to Cindy Perman, writer for the CNBC Blog,

"As analysts slice, dice, mince and wedge the president's first year in office, Zillow.com decided to take a look at his property's performance, and found that the value of 1600 Pennsylvania Avenue has dropped by $15.6 million, or 5.1 percent in the past year."
