2016 was the best year for the US housing market since the financial crisis
Although sales slumped in December - by 10.4% at a seasonally adjusted annual rate of 536,000 in December - new home sales were at the strongest level since 2007 for the year 2016.
Also, data from the National Association of Realtors on Tuesday showed that in 2016, existing home sales were at the strongest level since 2006.
Tight inventory, the recent rise in mortgage rates, and freezing weather may have contributed to the drop in December.
"We expect the upcoming year to bring both headwinds and tailwinds," said Ralph McLaughlin, Trulia's chief economist. "While higher mortgage rates blow strongly into the face of homebuyers, low existing inventory, near full employment, and rising wages are strong tailwinds that will continue to push new home sales higher in the year ahead."
