While the partial government shutdown means federal data on December new home sales have not been released, Redfin data show single-family new-home sales volume dropping 11.6 percent from the year before.
The Northeast, South, West and Southwest all saw double-digit drops in new-home sales last month .
"All around the country, homebuyers were backing off at the end of last year due to high prices and high mortgage interest rates," said Redfin Chief Economist Daryl Fairweather in an analysis of the data.
However, Redfin data show Houston fared better than the market overall. Sales of newly built single-family homes actually increased 6 percent from the year before, continuing a 13-month streak of year-over-year gains.
