ANALYSIS

"Home prices continued to rise across the country with the S&P CoreLogic Case-Shiller National Index rising at the fastest annual rate since June 2014," says David M. Blitzer, Managing Director and Chairman of the Index Committee at S&P Dow Jones Indices. "Home prices were higher in all 20 cities tracked by these indices compared to a year earlier; 16 cities saw annual price increases accelerate from last month. Strength continues to be concentrated in the west with Seattle, Las Vegas, San Diego and Portland seeing the largest gains. The smallest increases were in Atlanta, New York, Miami, Chicago and Washington. Eight cities have surpassed their pre-financial crisis peaks."

"Most economic indicators suggest that home prices can see further gains. Rental rates and home prices are climbing, the rent-to-buy ratio remains stable, the average rate on a 30-year mortgage is still under 4%, and at a 3.8-month supply, the inventory of homes for sale is still low. The overall economy is growing with the unemployment rate at 4.1%, inflation at 2% and wages rising at 3% or more. One dark cloud for housing is affordability – rising prices mean that some people will be squeezed out of the market."
