Case-Shiller Index Shows Home Values Rising In Detroit

Case-Shiller Index December 2011

Standard & Poors released its December 2011 Case-Shiller Index this week. The report is the most widely-cited, private-sector metric for the housing market. The index aims to measures change in home prices from month-to-month, and from year-to-year, in select U.S. cities and nationwide.

According to the report, between November and December 2011, home values fell within 18 of the Case-Shiller Index’s 20 tracked markets; and through the 12 months leading up to December 2011, 19 of 20 tracked markets fell.

Only Detroit posted year-over-year gains, adding 0.50% since December 2010

Now, these statistics may look dire for the housing market, but it’s important to remember that the Case-Shiller Index — though widely-cited — remains a flawed statistic for everyday buyers and sellers in Phoenix. Rather, the monthly Case-Shiller Index is more appropriately applied by policy-makers and economists to macro-economic issues than by you and me for buy-or-sell decisions..

There are three ways in which Case-Shiller is flawed — each tied to the way by which Case-Shiller Index is calculated.

The first reason why the Case-Shiller Index is flawed is that, although it’s purported to be a “national” housing index, the index tracks just 20 cities nationwide. The United States, by comparison, houses more than 3,100 municipalities. The Case-Shiller Index is not a representative sample of the U.S. housing market.

And then, even within its tracked markets, Case-Shiller fails provide sufficient details to be useful.

Within each Case-Shiller Index city, there are innumerable “local markets”, each with its own local economy. When home values are shown to be falling in Phoenix, for example, that doesn’t mean that values are falling everywhere in Phoenix — only in the aggregate. There are multiple neighborhoods in Phoenix in which home values improved in December.

The Case-Shiller Index doesn’t capture that. 

As another reason to ignore the Case-Shiller Index, note that the Case-Shiller Index only includes home sale data for single-family, detached homes — sales of condominiums and of multi-unit homes are specifically excluded. In some markets — Chicago and New York, for example — sales of these types can represent a large percentage of overall monthly sales.

Lastly, as a third reason to reduce the Case-Shiller Index’s significance — it’s “old”.

The Case-Shiller Index is published on a 60-day delay and includes sales contracts from even 60 days prior to that. In other words, the data used in this week’s Case-Shiller Index dates back to October 2011.

Data from 5 months ago is of little relevance to buyers in California today. Up-to-date and current information is what matters.

For actionable, real-time housing market data, therefore, look past the Case-Shiller Index. Look to your local real estate agent instead.

Case-Shiller Index Says Detroit And Washington DC Lead The Market

Case-Shiller Annual Change November 2011

Standard & Poors released its November 2011 Case-Shiller Index this week. The index measures the change in home prices from month-to-month, and year-to-year, in select U.S. cities.

According to the data, for the second straight month, home values fell in 19 of the Case-Shiller Index’s 20 tracked markets. In addition, also for the second straight month, Phoenix, Arizona was the lone Case-Shiller-tracked city in which home values rose.

Overall, November’s Case-Shiller Index showed a 1 percent decrease in home values between October and November 2011, and a near-4 percent decrease between November 2010 and 2011, putting home values at roughly the same levels as 8 years ago. Don’t read too far into it, however.

The Case-Shiller Index, though widely-cited, remains widely-flawed.

As a buyer or seller , relying on the Case-Shiller Index for market research can lead you to improper conclusions. To understand the Case Shiller Index’s methodology is to understand why.

First, the Case-Shiller Index draws its data from a very limited geography.

There are more than 3,100 municipalities nationwide. The Case-Shiller Index tracks just 20 of them. And they’re not the 20 largest, either. Four of the Top 10 Most Populous U.S. Cities are excluded (Houston, Philadelphia, San Antonio, San Jose) whereas Minneapolis and Tampa are not.

Minneapolis is the 48th largest city in the United States. Tampa is #55.

Next, when Case-Shiller Index gathers its data from its 20 cities, it only includes the home sale data of single-family, detached homes. This means that sales of condominiums and multi-unit homes are specifically excluded from the index. There are some cities — Chicago and New York, for example — where condominium sales represent a large percentage of the overall market.

The Case-Shiller Index ignores that.

And, lastly, when the Case-Shiller Index is published, it’s published on a 60-day delay. Its data is not “current”, therefore, and does little to tell buyers and sellers of Tucson and the country what’s happening in their home markets right this minute. Instead, the Case-Shiller Index tells us how the housing market looked two months ago.

If you’re active in the real estate market, either as a buyer or a seller, the Case-Shiller Index does you little good. For real-time data that actionable, speak to a real estate professional instead. It’s where you’ll find your best, most reliable and relevant information.

Nationally, Home Prices Off 18.3 Percent From April 2007 Peak

Home Price Index since April 2007 peakThe government confirms what the private-sector Case-Shiller Index reported yesterday. Nationwide, average home values slipped in October.

The Federal Home Finance Agency’s Home Price Index shows home values down 0.2% on a monthly, seasonally-adjusted basis. October marks just the second time since April that home values fell month-over-month.

The Case-Shiller Index 20-City Composite showed values down 0.7 percent from September to October.

As a home buyer , it’s easy to look at these numbers and think housing markets are down. Ultimately, that may prove true. However, before we take the FHFA’s October Home Price Index at face value, we have to consider the report’s flaws.

There are three of them — and they’re glaring. As we address them, it becomes clear that the Home Price Index — like the Case-Shiller Index — is of little use to everyday buyers and sellers.

First, the FHFA Home Price Index only tracks home values for homes backed by Fannie Mae or Freddie Mac mortgages. This means that homes backed by the FHA, for example, are specifically not computed in the monthly Home Price Index.

In 2007, this was not as big of an issue as it is today. in 2007, the FHA insured just 4 percent of the housing market. Today, the FHA is estimated to have more than one-third of the overall housing market.

This means that one-third of all home sales are excluded from the HPI — a huge exclusion.

Second, the FHFA Home Price Index excludes new home sales and cash purchases, accounting for home resales backed by mortgages only. New home sales is a growing part of the market, and cash sales topped 29 percent in October 2011.

Third, the Home Price Index is on a 60-day delay. The above report is for homes that closed in October. It’s nearly January now. Market momentum is different now. Existing Home Sales and New Home Sales have been rising; homebuilder confidence is up; Housing Starts are showing strength. In addition, the Pending Home Sales Index points to a strong year-end.

The Home Price Index doesn’t capture this news. It’s reporting on expired market conditions instead.

For local, up-to-the-minute housing market data, skip past the national data. You’ll get better, more relevant facts from a local real estate agent.

Since peaking in April 2007, the FHFA’s Home Price Index is off 18.3 percent.
