"This week's release of the April S&P-Case Shiller® house price indexes offered a few surprises. The decline in the 20-city composite index was less than that in March and eight cities had positive monthly growth in April – compared to only two cities in March. In addition, May's new home median sales price increased from the prior month, according the Commerce Department. It should be noted, however, that seasonality may have played a factor in these results."
