(RTTNews) - Existing home sales in the U.S. unexpectedly increased in the month of October, according to a report released by the National Association of Realtors on Monday. "Home sales remain resilient, despite low inventory and increasing affordability challenges," said NAR's chief economist Lawrence Yun. He added, "Inflationary pressures, such as fast-rising rents and increasing consumer prices, may have some prospective buyers seeking the protection of a fixed, consistent mortgage payment."
