YEAR-OVER-YEAR

The S&P CoreLogic Case-Shiller U.S. National Home Price NSA Index, covering all nine U.S. census divisions, reported a 5.6% annual gain in May, the same as the prior month. The 10-City Composite annual increase came in at 4.9%, down from 5.0% the previous month. The 20-City Composite posted a 5.7% year-over-year gain, down from 5.8% in April.

Seattle, Portland, and Denver reported the highest year-over-year gains among the 20 cities. In May, Seattle led the way with a 13.3% year-over-year price increase, followed by Portland with 8.9%, and Denver overtaking Dallas with a 7.9% increase. Nine cities reported greater price increases in the year ending May 2017 versus the year ending April 2017. 

MONTH-OVER-MONTH

Before seasonal adjustment, the National Index posted a month-over-month gain of 1.0% in May. The 10-City Composite posted a 0.7% increase and 20-City Composite reported a 0.8% increase in May.  After seasonal adjustment, the National Index recorded a 0.2% month-over-month increase. The 10-City Composite remained stagnant with no month-over-month increase. The 20-City Composite posted a 0.1% month-over-month increase. All 20 cities reported increases in May before seasonal adjustment; after seasonal adjustment, 14 cities saw prices rise.

ANALYSIS

"Home prices continue to climb and outpace both inflation and wages," says David M. Blitzer, Managing Director and Chairman of the Index Committee at S&P Dow Jones Indices. "Housing is not repeating the bubble period of 2000-2006: price increases vary across the country unlike the earlier period when rising prices were almost universal; the number of homes sold annually is 20% less today than in the earlier period and the months' supply is declining, not surging. The small supply of homes for sale, at only about four months' worth, is one cause of rising prices. New home construction, higher than during the recession but still low, is another factor in rising prices.

"For the last 19 months, either Seattle or Portland OR was the city with fastest rising home prices based on 12-month gains. Since the national index bottomed in February 2012, San Francisco has the largest gain. Using Census Bureau data for 2011 to 2015, it is possible to compare these three cities to national averages. The proportion of owner-occupied homes is lower than the national average in all three cities with San Francisco being the lowest at 36%, Seattle at 46%, and Portland at 52%. Nationally, the figure is 64%. The key factor for the rise in home prices is population growth from 2010 to 2016: the national increase is 4.7%, but for these cities, it is 8.2% in San Francisco, 9.6% in Portland and 15.7% in Seattle. A larger population combined with more people working leads to higher home prices."

The S&P CoreLogic Case-Shiller Indices are published on the last Tuesday of each month at 9:00 am ET. They are constructed to accurately track the price path of typical single-family homes located in each metropolitan area provided. Each index combines matched price pairs for thousands of individual houses from the available universe of arms-length sales data. The S&P CoreLogic Case-Shiller U.S. National Home Price Index tracks the value of single-family housing within the United States. The index is a composite of single-family home price indices for the nine U.S. Census divisions and is calculated quarterly. The S&P CoreLogic Case-Shiller 10-City Composite Home Price Index is a value-weighted average of the 10 original metro area indices. The S&P CoreLogic Case-Shiller 20-City Composite Home Price Index is a value-weighted average of the 20 metro area indices. The indices have a base value of 100 in January 2000; thus, for example, a current index value of 150 translates to a 50% appreciation rate since January 2000 for a typical home located within the subject market.

These indices are generated and published under agreements between S&P Dow Jones Indices and CoreLogic, Inc.

The S&P CoreLogic Case-Shiller Indices are produced by CoreLogic, Inc. In addition to the S&P CoreLogic Case-Shiller Indices, CoreLogic also offers home price index sets covering thousands of zip codes, counties, metro areas, and state markets. The indices, published by S&P Dow Jones Indices, represent just a small subset of the broader data available through CoreLogic.
