The White House says President Barack Obama and first lady Michelle Obama hold assets worth between nearly $2.6 million and nearly $8.3 million.
The White House released financial disclosure documents Tuesday showing the couple's assets for last year. The first family's assets were valued between $1.8 million and nearly $12 million in 2010.
The disclosure form requires public officials to list their assets in broad ranges, for example, between $1 million and $5 million, making it difficult to determine a precise net worth.
The Obamas have a 30-year mortgage on their Chicago home worth between $500,000 and $1 million with an interest rate of 5.625 percent.
Royalties from Obama's books, "Dreams From My Father," ''The Audacity of Hope" and "Of Thee I Sing," totaled between $250,000 and $2.1 million.
