Please note that transaction records for December 2020 for Wayne County, MI, are now available. Due to delays at the local recording office caused by the COVID-19 pandemic, S&P DJI and CoreLogic were previously unable to generate a valid December 2020 update for the Detroit S&P CoreLogic Case-Shiller Indices.
The S&P CoreLogic Case-Shiller U.S. National Home Price NSA Index, covering all nine U.S. census divisions, reported an 11.2% annual gain in January, up from 10.4% in the previous month. The 10-City Composite annual increase came in at 10.9%, up from 9.9% in the previous month. The 20-City Composite posted an 11.1% year-over-year gain, up from 10.2% in the previous month.
Phoenix, Seattle, and San Diego continued to report the highest year-over-year gains among the 20 cities in January. Phoenix led the way with a 15.8% year-over-year price increase, followed by Seattle with a 14.3% increase and San Diego with a 14.2% increase. All 20 cities reported higher price increases in the year ending January 2021 versus the year ending December 2020.
Before seasonal adjustment, the U.S. National Index posted a 0.8% month-over-month increase, while the 10-City and 20-City Composites both posted increases of 0.8% and 0.9% respectively in January. After seasonal adjustment, the U.S. National Index posted a month-over-month increase of 1.2%, and the 10-City and 20-City Composites both posted increases of 1.2% as well. In January, 19 of 20 cities reported increases before seasonal adjustment, and all 20 cities reported increases after seasonal adjustment.
"The strong price gains that we observed in the last half of 2020 continued into the first month of the new year. In January 2021, the National Composite Index rose by 11.2% compared to its year-ago levels," says Craig J. Lazzara, Managing Director and Global Head of Index Investment Strategy at S&P DJI. "The trend of accelerating prices that began in June 2020 has now reached its eighth month and is also reflected in the 10- and 20-City Composites (up 10.9% and 11.1%, respectively). The market's strength is broadly-based: all 20 cities rose, and all 20 cities gained more in the 12 months ended in January 2021 than they had gained in the 12 months ended in December 2020.
"January's performance is particularly impressive in historical context. The National Composite's 11.2% gain is the highest recorded since February 2006, just one month shy of 15 years ago. In more than 30 years of S&P CoreLogic Case-Shiller data, January's year-over-year change is comfortably in the top decile. That strength is reflected across all 20 cities. January's price gains in every city are above that city's median level, and rank in the top quartile of all reports in 18 cities.
"January's data remain consistent with the view that COVID has encouraged potential buyers to move from urban apartments to suburban homes. This demand may represent buyers who accelerated purchases that would have happened anyway over the next several years. Alternatively, there may have been a secular change in preferences, leading to a shift in the demand curve for housing. Future data will be required to analyze this question.
"Phoenix's 15.8% increase led all cities for the 20th consecutive month, with Seattle (+14.3%) and San Diego (+14.2%) close behind. Although prices were strongest in the West (+11.7%), gains were impressive in every region."
