National home prices increased 18% year over year in October 2021, according to the latest CoreLogic Home Price Index (HPI®) Report . The October 2021 HPI gain was up from the October 2020 gain of 7.4% and was the highest 12-month growth in the U.S. index since the series began in 1976. The increase in home prices was fueled by low mortgage rates, low for-sale supply and an influx in homebuying activity from investors. Projected increases in for-sale supply and moderation in demand as prices grow out of reach for some buyers could slow home price gains over the next 12 months.
