Dec 7 (Reuters) - U.S. household wealth fell to roughly $151 trillion in the third quarter, pulled down by a drop in the value of stocks which more than offset a half-trillion rise in the value of property prices, the Federal Reserve said on Thursday.

Household net worth fell about 1% in the period from July through September from $152.3 trillion at the end of the second quarter, the Fed said in its quarterly snapshot of the balance sheets of households and businesses.

The value of holdings of real estate increased $500 billion, while equity values declined $1.7 trillion. (Reporting by Lindsay Dunsmuir and Ann Saphir; Editing by Chizu Nomiyama)
