Standard & Poor's Case-Shiller Index reports another annual home value increase in last year, highlighting what many of today's home buyers have found out the hard way -- the housing market continues to expand.
Homes are more expensive as compared to last year, as home equity builds in nearly all U.S. markets. The shift has helped existing homeowners to refinance to current mortgage rates, but the rise in values has done little to help today's buyers.
Large downpayment or no downpayment, homes are more expensive than they were one year ago. Thankfully, mortgage rates have remained cheap.
Standard & Poor's recently released its July 2014 Case-Shiller Index. The index tracks home price changes both from month-to-month, and from year-to-year, in select cities nationwide. Tracked cities include San Diego, California; Los Angeles, California; and Phoenix, Arizona.
As compared to June, home values rose in 19 of the 20 tracked markets in July, led by a 1.1 percent gain within the five boroughs of New York City -- Manhattan, Queens, Brooklyn, Yonkers, and Staten Island.
Detroit, Michigan was the next biggest gainer, adding 0.9 percent month-over-month.
Only homes in San Francisco failed to add value in July. The Case-Shiller Index shows home values dropping 0.4 percent in San Francisco from June to July of this year.
On an annual basis, however, all of the Case-Shiller Index's 20 tracked markets are winners, led by Las Vegas, Nevada in which home values have climbed close to thirteen percent from last year.
Homes in Miami, Florida and San Francisco have also posted double-digit growth from last year. Home values have gained 11.0% and 10.3%, respectively, since July of last year.
The "weakest" of the Case-Shiller Index cities is Cleveland, Ohio. Home values are up just 0.9% over the last 12 months.
However, take care to not use Case-Shiller Index data for your personal "buy or rent" decisions in housing. The monthly index from S&P is flawed and may push you toward improper conclusions.
The index's first flaw is its most obvious -- its limited sample set.
The Case-Shiller Index tracks 20 U.S. metropolitan markets and brands itself a national index. Yet, according to Wikipedia, the U.S. is home to more than 3,100 individual municipalities.
This means that the Case-Shiller Index tracks fewer than one percent of all U.S. cities. Furthermore, its 20 tracked cities tracked aren't the nation's 20 most populous.
Four of the 10 most populous U.S. Cities -- Houston, Texas; Philadelphia, Pennsylvania; San Antonio, Texas; and San Jose, California -- are notably absent from the Case-Shiller Index 20-City Composite. By contrast, smaller cities such as Minneapolis, Minnesota (#48) and Tampa, Florida (#55) are not excluded.
The "national" Case-Shiller Index, in other words, is not very national at all.
Even on a city-by-city basis, the Case-Shiller Index gets it wrong. This is because the index lumps disparate city neighborhoods into a single, city-wide reading.
In Chicago, for example, where home values increased 4.0% over the past 12 months, some neighborhoods out-gained others. Values in Lincoln Park and Lakeview are different from values in Wicker Park and Bucktown, as examples. Yet, to the Case-Shiller Index, Paulina, Melvina, and Lunt Avenue are treated equally.
A second Case-Shiller Index flaw is its methodology.
The index considers only "repeat sales" of the same home in its findings, and those homes are required to be single-family, detached properties. This means that condominiums, multi-family homes, and new construction are not included.
In some cities, these "excluded" property types account for a large percentage of total monthly sales. New York City meets this criteria with its heavy concentration of condos and co-ops, as does Chicago, Boston, and, to a lesser extent, Los Angeles whose footprint extends into Orange County.
In Boston, condos increased in value by 6.6% as compared to 5.7% for the single-family homes. In Chicago, condos grew 4.7 percent.
With its limited property type set, Case-Shiller captures only a portion of the overall housing market.
A third Case-Shiller Index flaw is the "age" of its data.
Because Standard & Poor's publishes on a 60-day delay, the Case-Shiller Index is reporting on a housing market that no longer exists. But, the data is even older than that.
Home sales tracked by the July Case-Shiller Index are those which closed in July. However, July closings are based on contracts written in April, May, and June. This means that the Case-Shiller Index is only now reporting upon sales "made" in spring fall and the start of summer -- as much as half a year ago!
In the spring, the U.S. housing market was different. Mortgage rates were different, consumer sentiment was different, and even Federal Reserve policy was different.
The Case-Shiller Index's time lag may not matter much to economists and policy-makers; persons whom are occupied with long-term trends in housing. But, to individual buyers and sellers of real estate, the time lag makes the index almost useless for everyday use.
For home buyers, the Case-Shiller Index will never be your "real-time" real estate indicator. However, does a good job of highlighting broader valuation trends in housing. And, going on two years, home values are rising.

The Mortgage Reports has been a valuable asset to me. I love that each topic is fully explained in terms that can be easily understood. I've learned more from this web site than from any first-time buyer education class.
