SILVER SPRING, Md. — The number of Americans who signed contracts to buy homes declined last month, but was a record high for November when a seasonal slowdown traditionally seeps into the real estate market.

The National Association of Realtors said today that its index of pending sales fell 2.6% to 125.7 in November, down from October’s revised reading of 129.1. An index of 100 represents the level of contract activity in 2001. It was the third straight monthly decline.

Contract signings are a barometer of finished purchases during the next two months, so the report could preview what could be a strong winter for the housing market.

Contract signings are 16.4% ahead of where they were last year, thanks to a big summer rebound that followed a spring washout due to the coronavirus outbreak. Contract signings in all four regions — the Northeast, South, Midwest and West — declined from October to November but are up double-digits year-over-year through last month.

Historically low interest rates are drawing prospective buyers into the market, but home prices have risen significantly the past year as supply remains near all-time lows.

U.S. home prices jumped 7.9% in October, the most June 2014, according to S&P CoreLogic Case-Shiller 20-city home price index released Tuesday.

Mortgage finance giant Freddie Mac reported last week that the average rate on the 30-year fixed-rate home loan remained at a record low 2.66%.
