Home price growth continued to slow in June according to Case-Shiller’s 20-City Home Price Index. 17 cities reported higher home prices in June, but three cities reported lower home prices month-to-month. Seattle, Washington was the only city to report lower home prices year-over-year in June.

Phoenix, Arizona Home Price Growth Highest in June

Phoenix, Arizona toppled Last Vegas, Nevada’s hold on first place for home price growth in June. According to Case-Shiller’s 20-City Home Price Index, home prices in Phoenix rose by 5.80 percent year-over-year in June. Las Vegas, Nevada followed closely with year-over-year home price growth of 5.50 percent. Tampa, Florida had the third highest rate of home price growth with a year-over-year reading of 4.70 percent.

Home prices also slowed nationally; Case-Shiller reported 3.10 percent growth as compared to May’s year-over-year pace of 3.30 percent growth in home prices.

Home Buyers Leaving High-Cost West Coast

Analysts pointed out that recent slowing in home price growth followed a long period of rapidly rising home prices and higher mortgage rates. This sidelined many buyers as cash buyers and investors competed for fewer available homes. First-time and moderate income buyers could not afford rapidly rising prices and mortgages. Stricter mortgage loan requirements put in place after the Great Recession made qualifying for home loans more difficult.

Homeowners may not be seeing top pricing, buyer competition and offers higher than their asking prices, but after the long and fast increase in home prices, many sellers stand to realize significant profits after years of gains. At the height of the housing recovery, cities on the west coast saw steep rises in home prices. Seattle, Washington, Portland, Oregon and San Francisco, California enjoyed rapid home price growth as buyers paid cash and outbid each other, but lagging home price growth suggests that sky-high home prices have peaked in the West.

Seattle, Washington was the first city to show a year-over-year drop in home prices. Low mortgage rates may encourage formerly sidelined home buyers to enter the housing market. Analysts said that the only obstacle to increasing home sales might be homeowners unwilling to sell as home prices ease. Consumer concerns over the economic impact of trade tariffs may delay decisions to buy a home as consumer costs continue to rise. Home builders share these concerns as the cost of imported building materials increases.

Case-Shiller Indices reported slower home price growth in March with a 3.70 percent gain year-over-year as compared to 3.90 percent home price growth for the year-over-year period in 2018. This was the slowest pace of home price growth in seven years.

The 20-City Home Price Index showed Las Vegas, Nevada as having the top year-over-year home price growth rate of 8.20 percent; Phoenix, Arizona had year-over-year home price growth of 6.10 percent. Tampa, Florida had the third highest growth rate for home prices at 5.30 percent. Analysts said that all three cities continue their recoveries from deep home price declines during the recession.

Did Home Prices Grow Too Fast?

David M. Blitzer, managing director and chairman of the S&P Dow Jones Index Committee, said that given strong economic signs in other sectors, housing should be doing better. He said that too-high home price gains may have caused slowing growth in home prices as fewer prospective buyers can afford skyrocketing home prices in many metro areas.

The 20-City Home Price Index showed New York City was the only metro area posting a negative growth rate in March; this was attributed to the region’s already high home prices. Fluctuating mortgage rates likely sidelined some prospective home buyers, especially first-time and moderate income buyers.

The U.S. Department of Housing and Urban Development reported that home affordability reached a ten-year low in the end of 2018. Coupled with short supplies of affordable homes and builders focusing on high end housing development, shortages of affordable homes are expected to continue, particularly in high demand metro areas.

Slower home price growth indicates that the rapid rise in home prices in recent years aren’t sustainable as fewer prospective buyers can afford to buy homes or cannot qualify for purchase money mortgages. When home prices rise faster than inflation and wages, home buyers encounter more challenges in their searches for affordable homes.
