It has actually gained "a lot" since November because of the growing expectation that Obama will be a 1-term president.
It lost exactly $44,833,000. Todays value of the white house is $251,617,000. At the peak of the boom it was worth $331,580,000. It was built in 1792 by slaves, free African-American laborers, immigrants, and salaried Europeans. It cost $232,371.82 to build, so looks like it went up in value 1,000 times in the last 218 years. It is a 55,000 sq ft mansion on 18 acres, with 16 bedrooms and 35 bathrooms. (they need twice as many bathrooms because so many politicians in the white house are full of shit.) http://www.zillow.com/homedetails/1600-Pennsylvania-Ave-NW-Washington-DC-20006/84074482_zpid/
