Home Values Start The Year Strong

HPI 2007-2012

Home prices started the year on an upswing. 

According to the Federal Home Finance Agency’s Home Price Index, home prices rose by a seasonally-adjusted 0.3 percent between January and February 2012. The index is up 0.4% over the past year, offering a counter-story to the Case-Shiller Index’s assertion that home values are sinking.

Last week, Standard & Poor’s Case-Shiller Index said home values had dropped more than 3 percent in the prior 12 months. 

As a home buyer or seller , data showing “rising home values” or “falling home values” may be of interest to you, but we can’t forget that most home valuation trackers — including both the government’s Home Price Index and the private sector Case-Shiller Index — have a severe, built-in flaw.

Both used “aged” data. Today, the calendar reads May. Yet, we’re still discussing February’s housing data.

Data that is two-plus months old is of little value to everyday buyers and sellers wanting to know the “right now” of housing. And, even then, characterizing the data as “two-plus months old” may be a stretch. This is because the home values used in the Home Price index and the Case-Shiller Index are collected from actual transactions, but at the time of closing.

Considering that most purchases require 45-60 days to close, we can know that when we look at the Home Price Index and Case-Shiller Index reports for February, what we’re really seeing is a snapshot of the housing market as it existed two-plus month plus 60 days ago.

Data that’s 5 months old is of little relevance to today’s buyers and sellers. Today’s market is driven by today’s economics.

The Home Price Index is a useful gauge for economists and law-makers. It highlights long-term trends in housing which can be helpful in allocating resources to a particular project or policy. For home buyers and seller , though, it’s much less useful. Real-time data is what matters to you.

For that, talk to a real estate professional.

Case-Shiller Shows Uneven Recovery For U.S. Housing

Case-Shiller Home Value Changes

Recent data suggests that the U.S. housing market is in recovery. However, the data also shows this to be an uneven recovery.

According to the monthly S&P/Case-Shiller Index, for example, home values rose in three of 20 tracked markets between December 2011 and January 2012. 17 tracked markets showed home prices still in decline.

It’s easy to point to the Case-Shiller Index as evidence that the housing market has yet to bottom, but we have to consider the Case-Shiller Index’s shortcomings — specifically in a recovering economy.

For example, the Case-Shiller Index is based on changes in home prices of a single home, through successive sales. This means that to calculate its home price index, the Case-Shiller searches for sales of the same home over a period of time and calculates the difference in contract price. 

This methodology can distort the home price tracker downward during times of weak economy because there is no distinction made for homes sold in foreclosure or as a short sale.

35% of all homes sold in January were “distressed”, says the National Association of REALTORS®.

Another distortion in the Case-Shiller Index is that the model neglects all home types that are not of type “single-family residence”. This means that multi-unit homes and condominiums are excluded from the Case-Shiller Index model.

In some markets, such as Chicago and New York City, condominiums account for a large percentage of overall sales. 

Lastly, the Case-Shiller Index is published with a “lag”, which renders it useless to buyers and sellers in search of real-time, relevant data. The most recent Case-Shiller Index is published with a 60-day delay, and accounts for home purchase contracts written between October and December 2011.

Since October, the U.S. economy has added more than 1 million jobs and the economy has moved into “moderate expansion”, according to the Federal Reserve. Data that’s two seasons old does little to help us today.

Making sound real estate decisions is about having timely, relevant data at-hand when it’s needed. The Case-Shiller Index fails in that respect. It’s good for highlighting the U.S. housing market on the whole, as it existed in the past. For real-time market data, though, you’ll want to talk with an active real estate agent.

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. 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 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, Denver 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 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.

Case-Shiller Index : 17 Of 20 U.S. Housing Markets Slipped In September

Case-Shiller Index September 2011

Standard & Poor’s released its September 2011 Case-Shiller Index this week. The index tracks home price changes in select cities between months, quarters, and years.

The Case-Shiller Index for September showed drastic devaluations nationwide.

As compared to August, home values fell throughout 17 of the index’s 20 tracked markets, led by Atlanta’s 5.9% drop. On an annual basis, home values have now returned to early-2003 levels.

That said, home buyers and sellers should be cautious when referencing the Case-Shiller Index. The index is a flawed metric and, as such, can lead to improper conclusions about the housing market overall.

The Case-Shiller Index’s first flaw is its most obvious — its limited sample set. 

According to Wikipedia, there are more than 3,100 municipalities nationwide. Yet, the Case-Shiller Index includes data from just 20 of them in its findings. These 20 cities account for fewer than 1% of all U.S. cities, and just a small percentage of the overall U.S. population. 

The “national figures” aren’t really national, in other words.

Even on a city-by-city basis, the Case-Shiller Index gets it wrong.

By lumping disparate neighborhoods into a single, city-wide result, the index ignores the relative strength of one area at the expense of another. In the aforementioned Atlanta, there are areas that fared much better than September’s -5.9% as cited by Case-Shiller. Some areas fared much worse.

A second flaw in the Case-Shiller Index is it’s methodology for measuring changes in home value. The index only considers “repeat sales” of the same home in its findings, and those homes must be single-family, detached property. Condominiums, multi-family homes, and new construction are not included.

In some cities — Chicago, for example — “excluded” property types can account for a large percentage of total monthly sales.

And, third, the Case-Shiller Index is flawed by “age”.

Because Standard & Poor’s publishes on a 60-day delay, the Case-Shiller Index is reporting on a housing that no longer exists. Sales that closed in September are based on contracts written from June-August –a time-frame that’s 6 months aged.

The best use of the Case-Shiller Index is as an analysis tool for economists and policy-makers interested in the long-term trends of U.S. housing. The index does very little good for every day buyers and sellers, unfortunately.

For up-to-date, accurate market data, talk to a real estate professional instead.

Detroit Leads All Case-Shiller Cities In Home Price Improvement

Case-Shiller Annual Changes August 2011

The August 2011 Case-Shiller Index was released this week. On an monthly basis, 10 of 20 tracked markets worsened. On an annual basis, valuation degradation was worse.

Only Detroit and Washington, D.C. posted higher home values in August 2011 as compared to August 2010, rising 2.7% and 0.3%, respectively.

However, the index has been moving in the right direction. Since bottoming out in March of this year, the Case-Shiller Index is up nearly 4 percent.

As home buyers and sellers , though, we have to remember that the Case-Shiller Index is a flawed product; its methodology too narrow to be the final word for housing markets.

The Case-Shiller Index has 3 main flaws.

The first Case-Shiller Index flaw is its relatively small sample size. Although it’s positioned as a national housing index, Case-Shiller data represents just 20 cities nationwide, and they’re not even the 20 most populous U.S. cities. For example, cities like Houston (#4), Philadelphia (#5), San Antonio (#7) and San Jose (#10) are excluded from the Case-Shiller Index findings.

By contrast, Minneapolis (#48) and Tampa (#55) make the list.

A second Case-Shiller Index flaw is the way in which it measures home price changes. The Case-Shiller Index formula ignores all home sales except for “repeat sales” of the same home. New homes don’t count for the Case-Shiller Index. Furthermore, the index ignores condominium and multi-family home sales, too. 

In some cities, condos can account for a large percentage of sales.

And the third Case-Shiller Index flaw is that the data is reported on a 2-month lag. Next week marks the start of November, yet we’re still discussing data from August. A lot can change in two months (and it often does). Today’s market conditions are similar to — but not the same as — market conditions from before Labor Day.

The Case-Shiller Index is far from “real-time”.

As a monthly release, the Case-Shiller Index does more to help people with a long-term view of housing, including politicians and economists, than it does for everyday buyers and sellers who negotiate prices based on current demand and supply.

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.

Case-Shiller Index : 85% Of Tracked Cities Showed Home Price Improvement In July

Case-Shiller monthly change (June - July 2011)

Standard & Poors released its monthly Case-Shiller Index this week. The Case-Shiller Index measures home price changes from month-to-month, and year-to-year, in 20 select U.S. cities. It also reports a “national” index; a composite of the values in said cities.

The most recent Case-Shiller Index shows a 0.9% rise in home values from June to July 2011. Home values were higher in 17 of the 20 tracked cities. Only Phoenix and Las Vegas fell. Denver was flat.

Also noteworthy is that, of all of the Case-Shiller cities, Detroit posted the strongest 1-year, home price improvement. As compared to July 2010, home values are higher by 1.2 percent in Detroit. This bests even Washington, D.C. — long-believed to be the nation’s healthiest housing market.

That said, we should be careful of the conclusions we draw from July’s Case-Shiller Index — both on a city-wide level, and on a national level. This is because, as with most “home price trackers”, the Case-Shiller Index has flaws in its methodology. 

The first Case-Shiller Index flaw is its limited scope. Although it’s purported to be a “nationa”l housing index, the data that comprises the monthly Case-Schiller Index is sourced from just 20 U.S. cities. These 20 cities represent just 0.6% of the more than 3,100 municipalities nationwide.

The second Case Shiller Index flaw is that the sample sets include single-family, detached homes only. iCondominiums, multi-unit homes, and new construction are specifically excluded from the Case-Shiller Index.

In some markets, “excluded” home types outnumber included ones.

And, lastly, the Case-Shiller Index is flawed in that it takes 2 months to gather data and report it. It’s nearly October, yet we’re still discussing the real estate market as it existing in July. For buyers and sellers , July in ancient history. 

The Case-Shiller Index is useful for tracking long-term trends in housing, but does little to help individuals with their choices to buy or sell a home. For relevant, recent real estate data, talk to a real estate agent in your market. Real estate agents are often the best source for real-time, real estate data.

Home Values Rose In June 2011

Case-Shiller Changes May to June 2011

Has housing possibly turned the corner for good?

The June 2011 Case-Shiller Index reading posted strong numbers across the board, with each of the index’s 20 tracked markets showing home price improvement from May.

Some markets — Chicago and Minneapolis — rose as much as 3.2 percent.

The rise in values is nothing about which to get overly excited, however. The Case-Shiller Index is just re-reporting what multiple data sets have already shown about the summer housing market; that it was stronger than the spring market, and that a recovery is underway and at very different rates in various areas.

For example, the June 2011 Case-Shiller Index shows the following :

  • Denver, Dallas, Washington D.C., and the “California Cities” bottomed in 2009. Each has shown rather steady improvement since.
  • None of the Case-Shiller cities showed negative growth between May and June 2011.
  • 12 of Case-Shiller’s tracked cities have improved over 3 consecutive months.

In isolation, these statistics appear promising, but it’s important to remember that the Case-Shiller Index is a backward-looking data set, focusing on just a portion of the national housing economy.

As an illustration, the Case-Shiller Index’s “national report” only includes data from 20 cities nationwide. They’re not the 20 biggest cities, either. Smaller metropolitan areas such as Minneapolis (#48) and Tampa (#51) are included.

Larger ones including Houston (#4), Philadelphia (#5) and San Jose (#10) are not.

In addition, the Case-Shiller index fails to track sales of condominiums, multi-unit homes and new construction. In some markets, including Chicago, these excluded home type can represent a large share of the overall market.

The Case-Shiller Index is a fine data set for policy makers and economists. It describes the broader housing market and shows long-term trends. For the individual home buyer , however, it’s much less useful. More than “broad data”, you want focused data that’s current and relevant.

The best place for data like that is a local real estate agent.

January 2011 Case-Shiller Index : Weak And Flawed

Case-Shiller Annual Change January 2011

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 three 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 metro areas 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 resale data from January which is really comprised of homes that went under contract from October through December– up to five months ago. Sales prices from so long ago are 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.
