Economists had forecast the sales pace of 710,000 last month.
December's sales pace was revised up to 708,000 units (+2.3 percent m-o-m) from the originally reported 694,000 units (-0.4 percent m-o-m).
According to the report, the January climb in purchases of new homes was due to gains in three of four U.S. regions, led by the Midwest (30.3 percent m-o-m) and West (+23.5 percent m-o-m).
In y-o-y terms, new home sales recorded an 18.6 percent jump in January.
