Case-Shiller Shows Home Price Improvement In 90% Of Cities

Standard & Poors released its Case-Shiller Index Tuesday.  The index is a monthly home valuation report from select cities and among the private sector’s most popular home pricing models.

In reviewing the April Case-Shiller Index and its accompanying analysis, it appears that the housing market’s rebound is gathering momentum.

In the index’s 20 tracked cities:

• 18 of 20 improved from March to April 2010
• Versus April 2009, home prices are up nearly 4 percent
• The two “down” cities from April — Miami and New York — are off just 0.5% and 1.0% annually, respectively

Furthermore, as another sign of strength, San Diego, a city in which homeowners have lost a lot of equity since 2007, has now shown 12 straight months of home price improvement.

However, the Case-Shiller Index must be kept in context. It’s far from perfect.

For one, the index reports on a 60-day delay; it’s only now showing data from the end of April, when the federal homebuyer tax credit was expiring. Home sales have been weak since then it’s been reported.

And second, the Case-Shiller Index is limited to just 20 cities nationwide. Therefore, the index doesn’t consider every home sale in every American city — it only considers a select few. Many more U.S. homes are excluded from the Case-Shiller Index than are included.

But, despite its flaws, the Case-Shiller Index remains important with respect to economic analysis. Much like the government’s Home Price Index, Case-Shiller helps to identify broader trends in housing that shape government and monetary policy.
