Case-Shiller: Home price gains ease up in September

Price growth decelerated in 14 cities included in S&P CoreLogic Case Shiller's 20 city composite

Home prices have started to show signs of easing up as the S&P CoreLogic Case-Shiller national home price index rose 19.5% year-over-year in September, down from 19.8% the previous month. 

The 10-city composite increased 17.8% year-over-year in September, down from 18.6% in the previous month, and the 20-city composite climbed 19.1% year-over-year, down from 19.6% in the previous month. 


Phoenix, Arizona, and Tampa and Miami in Florida saw the largest year-over-year gains among the 20 cities in September, with increases of 33.1%, 27.7% and 25.2%, respectively. Meanwhile, the smallest increases were 11.8% in Chicago, 12.8% in Minneapolis, Minnesota, and 13.7% in Washington D.C.

Price growth decelerated in 14 of the 20 cities, while six reported higher price increases in the year ending September 2021 versus the year ending August 2021.

"If I had to choose only one word to describe September 2021′s housing price data, the word would be ‘deceleration.’ Housing prices continued to show remarkable strength in September, though the pace of price increases declined slightly," S&P Dow Jones Indices managing director Craig Lazzara said in a statement. "The strength in the U.S. housing market is being driven by households’ reaction to the Covid pandemic, as potential buyers move from urban apartments to suburban homes."


The latest home price data comes as existing home sales rose 0.8% in October to a seasonally adjusted rate of 6.34 million units, the fastest pace since January, while pending home sales, which tracks the number of homes that are under contract to be sold, rose 7.5% to a reading of 125.2 in October. 

The median existing home price in October jumped 13.1% year-over-year to $353,900, marking a record 116 straight months of year-over-year increases, while the median existing single-family home price jumped 13.5% year-over-year to $360,800 and the existing condo price rose 8.7% year-over-year to $296,700. 

First-time home buyers accounted for 29% of existing home sales in October, up from 28% in September and down from 32% in October 2020, while individual investors or second-home buyers purchased 17% of homes in October, up from 13% in September and 14% in October 2020.

Total housing inventory remains low, falling 0.8% month-over-month and 12% year-over-year in October to 1.25 million units. Unsold inventory, which is at a 2.4-month supply at the current sales pace, remains unchanged from the previous month and is down from 2.5 months a year ago. 

Though the housing market is expected to remain robust, National Association of Realtors chief economist Lawrence Yun predicts home prices will rise at a gentler pace over the course of the next several months and expects milder demand as mortgage rates increase. The average rate on a 30-year fixed-rate mortgage was 3.1% as of Nov. 24, according to Freddie Mac.
