None of the four major U.S. regions saw a gain in sales activity last month.

Total existing-home sales,, completed transactions that include single-family homes, townhomes, condominiums and co-ops, decreased 6.4 percent from November to a seasonally adjusted rate of 4.99 million in December. Sales are now down 10.3 percent from a year ago (5.56 million in December 2017).

Lawrence Yun, NAR’s chief economist, says current housing numbers are partly a result of higher interest rates during much of 2018. “The housing market is obviously very sensitive to mortgage rates. Softer sales in December reflected consumer search processes and contract signing activity in previous months when mortgage rates were higher than today. Now, with mortgage rates lower, some revival in home sales is expected going into spring.”
