U.S. housing sales, a key pillar of economic growth in recent years, are looking weaker again. Existing home sales declined for much of 2018. In December, according to the National Association of Realtors, sales of single-family homes, condos, and co-ops fell a larger-than-expected 6.4% from the previous month. A Reuters survey of economists projected home sales to decline by a modest 1% in December.
