According to an article written by Ben Leubsdorf and updated November 12, 2015 and published in the Wall Street Journal:

92% of economists surveyed see the Federal Reserve raising short-term interest rates as early as December 2015.
The Fed held its benchmark Federal Funds Rate near zero since December 2008 to bolster the U. S. economy through a financial crisis, deep recession and slow recovery. The rates have been held steady since 2008.
The policy meeting for the Fed Reserve is scheduled for December 15 – 16, 2015.
The results of this survey are consistent with most recent discussion on the subject of a near increase in short-term interest rates.
Homebuyers active in the market should recognize that delaying the purchase of their home would come with an additional cost.

UPDATE: The Federal Reserve Board voted on December 16, 2015, to increase interest rates by 0.25%.
