According to the Standard & Poors Case-Shiller Index, home values rose 5 percent in June versus the month prior, and 4 percent from a year earlier.  It’s the 16th consecutive month in which Case-Shiller reported an increase in home values and the third straight month of outstanding results.

That said, homeowners and home buyers in Atlanta would do well to temper Case-Shiller enthusiasm. The June figures are issued on 60-day delay and, over the last 60 days, housing data has been lackluster at best.

• Existing Home Sales are down 27 percent
• New Home Sales are down 12 percent
• Homebuilder confidence is down

Stories like these highlight a key weakness of the Case-Shiller Index — it’s out of date as soon as it’s published. Because of this, the Case-Shiller Index relevance to everyday Americans is muted. People don’t buy homes in the “60 days ago” real estate market, after all.

June is ancient real estate history to buyers and sellers in Buckhead.

However, the Case-Shiller Index does have its place. As the most widely-followed, private-sector housing tracker, the index is used to help make policy decisions and to shape Wall Street’s expectations of the economy. This means that a strong Case-Shiller reading can cause mortgage rates to rise, and a weak Case-Shiller reading can cause rates to fall.

Tuesday, mortgage rates fell.

Standard & Poors released its Case-Shiller Index Tuesday. On a seasonally-adjusted basis, between April and May 2010, home prices rose in 19 of Case-Shiller’s 20 tracked markets.  It’s the second straight month of strong Case-Shiller findings.

Also, May’s numbers are a mirror-image of February’s. In February, 19 of 20 markets lost value.

In its press release, the Case-Shiller staff resisted calling May’s data proof of a housing recovery, noting that home values remain flat as compared to October of last year. However, there are some noteworthy numbers in the Case-Shiller report.

1. 13 of the 20 tracked cities are showing home price improvement year-over-year
2. Foreclosure posterchlld San Diego has now shown 13 straight months of improvement
3. San Diego, San Francisco and Minneapolis are showing double-digit annual growth

These are all good signs for the housing market, but the Case-Shiller Index is not without its flaws. Most notably, the data is limited to just 20 cities nationwide — and they’re not even the 20 largest ones. 

Cities like Houston, Philadelphia, and San Jose are excluded from Case-Shiller, while cities like Tampa (#54) are not.

Another Case-Shiller flaw is that it reports on a 2-month delay.

Therefore, today is several days from the start of August but we’re now reflecting on data from May. Given the speed at which the Los Angeles real estate market can change, May’s data is almost ancient.  Today’s values may be higher or lower than what Case-Shiller reports.

For home buyers, reports like the Case-Shiller Index may not be useful in making a “Buy or Not Buy” decision, but can aid in watching longer-term trends in housing.  For real-time data, talk to a real estate agent with access to local figures instead.

Last week, the Case-Shiller Index reported home values up 0.8 percent across 20 tracked markets. The public-sector Federal Housing Finance Agency has reached a similar conclusion.

Reporting on a two-month lag, the government’s Home Price Index shows home values up 0.8 percent in April, buoyed by the expiring federal home buyer tax credit and low mortgage rates.  It’s a positive signal for a recovering housing market — in Atlanta and everywhere else.

But just because the Home Price Index says home values are rising, that doesn’t mean they are. The Home Price Index methodology is flawed on multiple fronts.

First, the Home Price Index reports on a 60-day delay. This two-month lag turns the HPI a trailing indicator for the housing market instead of a forward-looking one. If you’re a home buyer looking for direction, HPI won’t give it to you — you’ll have to get that analysis from your real estate agent.

Second, HPI only accounts for home values in which the home’s attached mortgage is backed by Fannie Mae or Freddie Mac.  As the FHA market share grows, fewer homes get included in the HPI sample set, and HPI values may be skewed high or low.

And, third, HPI doesn’t account for new home sales — only repeat ones.  This, too, eliminates a major segment of the market.

All of that said, though, the Home Price Index remains important to housing.  It’s still the most comprehensive home valuation model in print and it’s been giving strong readings since the start of year.  You can’t ignore that on any level.

It’s July and you may have missed the “rock bottom” Buckhead home prices from earlier in the year, but homes are still relatively inexpensive. Couple that with all-time low mortgage rates and home affordability looks excellent. Consider making an offer while the terms are right.

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.

Earlier this week, Standard & Poors released its February Case-Shiller Index, a home price tracker for select metropolitan areas. 

Overwhelmingly, home values fell in the 20 markets tracked by the Case-Shiller. Only San Diego showed a modest increase.  The other 19 markets averaged a 1.23 percent decline between January and February.

However, that’s not the story you read in the most papers. Instead, headlines read that home values were up in the United States, citing annualized data.

Unfortunately for active home buyers and sellers, year-over-year data isn’t all that helpful when making a real estate decisions. It’s the month-to-month data that matters. Month-to-month changes in home prices are what defines a housing market. Month-to-month is what sets the tone for contracts and negotiations on a purchase.

The rosier, annualized data published this past week just doesn’t capture the reality of what was the February 2010 market.  And even then, the data is somewhat useless because it’s from February and May will be upon us next week.

Case-Shiller is on a 2-month lag — hardly reflective of the “right now” of real estate in Huntington Beach.

When you’re looking for real estate data that actionable, consider using sources that are more “real-time”. A real estate agent may be the right place to start.  Because for all the data that Case-Shiller and the other housing indices collect, it can never be as relevant to your individual needs as a well-executed, timely market analysis.

Standard & Poors released its Case-Shiller Index Wednesday. The report shows that, on a seasonally-adjusted basis, between December and January, home prices rose in more than half of the index’s tracked markets.

The strength of this month’s Case-Shiller report, however, should be put in context.

For one, the report is on a 2-month delay; it’s showing data from January, before the start of the Spring Buying Season and before the rush to beat the tax credit. Anecdotally, buyer interest has been strong since, leading to the types of multiple offer situations that drive home prices northward.

In other words, home values may be even higher than what’s reflected in the January Case-Shiller data above.

Furthermore, the Case-Shiller Index measures home values in just 20 cities nationwide and they’re not even the 20 biggest cities. Houston, Philadelphia, San Antonio and San Jose are specifically excluded from the report and each ranks among the country’s 10 most populous areas.

Despite its flaws, though, the Case-Shiller Index remains important. Much like the government’s Home Price Index, the private-sector report helps to finger broad housing trends and housing is still considered a keystone in the U.S. economic recovery.

Even if it’s two months slow.

Using data compiled in December, Standard & Poors released its Case-Shiller Index Tuesday.  The report shows home prices down just 2.5% on an annual basis, a figure much lower than the 8.7% annual drop reported after Q3.

According to Case-Shiller representatives, the housing market is “in better shape than it was this time last year”, but some of the summer’s momentum has been lost. 15 of 20 tracked markets declined in value between November and December 2009.

Meanwhile, it’s interesting to note the 5 markets that didn’t decline — Detroit, Los Angeles, Las Vegas, Phoenix and San Diego.  Each of these metro regions were among the hardest hit nationwide when home prices first broke.  Now, they’re leading the pack in price recovery.

For some real estate investors, that’s a positive signal.  But we also have to consider the Case-Shiller Index’s flaws because they’re big ones.

As examples:

1. Case-Shiller data is reported on a 2-month lag
2. The Case-Shiller sample set includes just 20 U.S. cities
3. There’s no “national real estate market” — real estate is local

That said, the Case-Shiller Index is still important. As the most widely-used private sector housing index, Case-Shiller helps to identify broader housing trends and many people believe housing is a key element in the economic recovery.

If the markets that led the housing decline will lead the housing resurgence, December’s data shows that full recovery is right around the corner.
