US existing home sales experienced a significant upturn in November, marking the fastest pace since March. Sales rose by 4.8%, reaching an eight-month high and posting the biggest annual gain since 2021. This increase is attributed to lower mortgage rates and an influx of properties for sale, attracting more buyers despite the ongoing high mortgage rates. Recent data shows existing home sales climbing to a 20-month high, indicating a positive trend in the housing market. However, experts caution that while current conditions are favorable, potential challenges lie ahead as higher rates could dampen future momentum.
