Case-Shiller Shows Home Values Rolling Back 9 Years

The March Case-Shiller Index was released this week and it corroborates the findings of the government's most recent Home Price Index -- home values are slipping nationwide.

According to the Case-Shiller Index's publisher, Standard & Poors, home values fell in March from the year prior.

The March report was among the worst Case-Shiller Index readings in 3 years. On a monthly basis, 18 of 20 tracked markets worsened. Only Seattle and Washington, D.C. showed improvement, rising 0.1% and 1.1%, respectively.

On an annual basis, price degradation was even worse.

Washington, D.C. is the only tracked market to post higher home values for March 2011 as compared to March 2010. The national index has now dropped to mid-2002 levels.

As a buyer in today's market, though, you can't take the Case-Shiller Index at face value. It's methodology is far too flawed to be the "final word" in home prices.

The first big Case-Shiller Index flaw is its relatively small sample size. S&P positions the Case-Shiller Index as a national index but its data comes from just 20 cities total. And they're not the 20 most populous cities, either. Notably missing from the Case-Shiller Index list are Houston (#4), Philadelphia (#5), San Antonio (#7) and San Jose (#10). 

Minneapolis (#48) and Tampa (#55) are included, by contrast.

A second Case-Shiller flaw is how it measures a change in home price. Because the index throws out all sales except for "repeat sales" of the same home, the Case-Shiller Index fails to capture the "complete" U.S. market. It also specifically excludes condominiums and multi-family homes. 

In some cities -- such as Chicago -- homes of these types can represent a large percentage of the market.

And, lastly, a third Case-Shiller Index flaw is that it's on a 2-month delay. It's June and we're only now getting home data from March. Today's market is similar -- but not the same -- to what buyers and sellers faced in March. The Case-Shiller Index is far less useful than real-time data of a city or neighborhood.

The Case-Shiller Index is more useful to economists and policy-makers than to everyday buyers and sellers. For better real estate data for your particular neighborhood, ask your real estate agent for help.

A real estate agent can tell you which homes have sold in the last 7 days, and at what prices. The Case-Shiller Index cannot.

January 2011 Case-Shiller Index : Weak And Flawed

Standard & Poors released its Case-Shiller Index for the month of January this week. The index is a home valuation tool, measuring the monthly and annual changes in home prices in select cities nationwide.

January's Case-Shiller Index gave a poor showing. As compared to December 2010, home values dropped in 19 of the Case-Shiller Index's 20 tracked markets. Only Washington, D.C. gained. The results were only modestly better on an annual basis, too.

18 of 20 markets worsened in the 12 months ending January 2011.

According to the report, values are down 3.1% from last year, retreating to the same levels from Summer 2003. As a buyer or seller in today's market, though, don't read too much into it. The Case-Shiller Index is far too flawed to be the final word in housing.

The index has 3 main flaws, in fact.

The first flaw is the Case-Shiller Index's lack of breadth. The report is positioned as a national index, but its data is sourced from just 20 cities nationwide.

Putting that number in perspective: the Case-Shiller Index tracks home values from fewer than 1% of the 3,100 U.S. municipalities -- yet still calls the report a "U.S. Average".

A second flaw in the Case-Shiller Index is how it measures home price changes, specifically. Because the index only considers "repeat sales" of the same home in its calculations, and only tracks single-family, detached property, it doesn't capture the "full" U.S. market. Condominiums, multi-family homes, and new construction are ignored in the Case-Shiller Index algorithm. 

In some regions, homes of these excluded types represent a large percentage of the market.

And, lastly, the Case-Shiller Index is flawed because of the amount of time required to release it.

Today, it's almost April and we're talking about closed home resales from January which is really comprised of homes that went under contract in October -- close to 6 months ago. Sales prices from 6 months ago is of little value to today's home buyer, of course.

The Case-Shiller Index can be a helpful tool for economists and policy-makers trying to make sense of the broader housing market, but it tends to fail for individuals like you and me. When you want accurate, real-time housing figures for your local market, talk to your real estate professional instead.

Why You Shouldn't Put Too Much Faith In October's Case-Shiller Index

The Case-Shiller Index posted awful numbers in its most recent reading. Each of the index's 20 tracked markets showed home price deterioration between September's and October's respective report. Some markets fell as much as 2.9 percent.

The drop in values is nothing about which to panic, however. The Case-Shiller Index is just re-reporting what we already knew. It's a common theme with the Case-Shiller Index, actually; a trait traced to the report's methodology.

The Case-Shiller Index is an imperfect housing indicator with 3 inherent flaws.

The first flaw is that the index makes use of a limited data set, tracking values in just 20 cities nationwide. That data set is then projected across the more than 3,100 other municipalities in the United States. The "national figures", therefore, aren't really national.

The second flaw is that, even within the tracked 20 cities, not all home sales are included. The Case-Shiller Index only tracks sales of single-family, detached homes, and within that market subset, it only uses homes that are "repeat sales". This specifically excludes sales of condominiums and multi-family homes, and new construction.

Lastly, Case-Shiller Index's third flaw is its "age". The Case-Shiller Index reports on a 60-day delay, and the values it reports are tied to contracts written even longer ago.  Sales contracts from July and August are responsible for October's closings so when we see the Case-Shiller Index as reported in December, some of the data it's reporting is 5 months old already. That's too old to be relevant.

Looking back at 2010, housing was at its weakest between May and August. Therefore, it's no surprise that the most recent Case-Shiller Index shows significant weakness.  Looking forward, we should expect the report to improve -- especially because of how strong New Home Sales and Existing Home Sales have been since summer.

The Case-Shiller Index is helpful for economists and policy-makers. It's not much good for individual homeowners, however. For accurate, real-time housing data, talk to a real estate professional instead.

Home Inventory Dwindles Into The New Year

Existing Home Sales jumped another 6 percent in November, the report's third month of improvement since bottoming in July.

According to the National Association of REALTORS®, a quarter-million more existing homes were sold during the annual period ending in November as compared to October.  An "existing home" is a home that cannot be considered new construction.

Additionally, the national housing supply dropped by a full month. At the current pace of existing home sales, the complete stock of homes for sale will be exhausted in 9.5 months.

November's strong housing data is yet another signal to buyers that the housing market's foundation has been rebuilt, and that a rebound is imminent.  It's helped that there are great "deals" on which for buyers to pounce.

In November, short sales and foreclosures accounted for one-third of all existing homes sold, and carried an average price discount of 10 percent and 15 percent, respectively, as compared to non-distressed sales.

Repeat buyers continue to power the market, too, representing more than half of all home buyers.

• First-time buyers : 32% of all buyers
• Investors : 19% of all buyers
• Repeat buyers : 51% of all buyers

This breakdown suggests that housing has regained its footing. First-time buyers can't support a market long-term like repeat buyers can and, as compared to 12 months ago, the percentage of repeat buyers is now up 14 points.

Home buyers take note. Raw sales volume is rising and available inventory is dropping. Basic supply-and-demand tells us that this will lead home prices higher. Furthermore, mortgage rates are rising quickly, increasing the cost of homeownership.

If buying a home is a part of your plan for 2011, consider accelerating your purchase time frame. Existing homes account for more than 80% of homes sold nationwide. If the market keeps improving like this, your home affordability will worsen.

Home Affordability Reaches Record-Levels... Last Quarter.

Last quarter, with home prices still relatively low and mortgage rates making new, all-time lows almost weekly, the cost of home ownership was extraordinarily low in utah and most U.S. markets.

According to the National Association of Home Builders' quarterly Home Opportunity Index, 72.5 percent of all new and existing homes sold between June-September 2010 were affordable to families earning the national median income. This ties the all-time high for home affordability, set in the first quarter of 2009.

The data also underscores that, when compared to historical norms, it's a fantastic time to be a home buyer.

Prior to 2009, the Home Opportunity Index rarely topped 65. The index has remained above 70 ever since.

All real estate is local, though, and on a city-by-city basis, home affordability varied last quarter.

For example, 96% of homes sold in Kokomo, IN are affordable for families earning the area's median income. This handily beat the average figure and led the nation. Looking at major cities, Indianapolis led the pack.

93% of homes in Indianapolis are affordable to families earning the area's median income. This ranks #9 nationwide.

On the opposite end of the affordability scale is the New York-White Plains, NY-Wayne, NJ region. For the 10th consecutive quarter, the New York Metro region ranks last in U.S. home affordability. Just 23% of homes are affordable to families earning the local median income, although this is 3 points higher versus Q1 2010.

The rankings for all 225 metro areas are available online.

Regardless of where your hometown ranks relative to its neighbors, home affordability remains high as compared to historical values. That said, with mortgage rates rising and home sales expected to climb this winter, it's unlikely that the Home Opportunity Index will improve.

Buying a home may never be this inexpensive again. If you planned to buy in mid-2011, consider moving up your time frame.

September's Case-Shiller Index Reflects A Slowing Housing Market

Standard & Poors released the September Case-Shiller Index Tuesday. The Case-Shiller Index is a home-value tracker. The report shows home prices down 0.7% from August and values fading, in general.

Case-Shiller representatives assessed the findings as "another weak report; weaker than last month", citing deterioration in 18 of 20 tracked markets. Upward pricing momentum from the summer is slowing and values remain 30% off the market's June 2006 peak. It could spell bad news for home sellers this winter.

That said, the Case-Shiller Index is imperfect; its methodology flawed. The index is not meant for use by individual buyers or sellers -- for 3 reasons.

First, the Case-Shiller Index reports on a 2-month delay. Today is December 1 and we're discussing data from September. In the 8 weeks since, the economy has shifted to a net jobs gainer, and the Federal Reserve has committed to $600 billion in re-investment.  These are major developments that weren't a part of September's housing market, but are relevant today.

Especially because employment is largely believed to be a keystone to housing.

Second, the Case-Shiller sample set is limited to just 20 cities nationwide. This means that most U.S. home sales are specifically not included in the Case-Shiller Index's monthly findings.

And that ties into reason number three -- all real estate is local. No matter what the Case-Shiller Index says about the country, what matters to your local market is what's happening in your local market. Each neighborhood has its own housing economy and that's something that can't be captured by a national report.
