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 in Carolinas 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 of Charlotte 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.

The housing market took a step back in February, but remains near post-recession highs.

According to data from the National Association of REALTORS®, February’s Pending Home Sales Index slipped 0.5 percent from the month prior, to 96.5.

The Pending Home Sales Index is a monthly report which measures the number of homes under contract to sell, but not yet sold, nationwide.

The index is benchmarked to a value of 100, the average level of home contract activity in 2001, the first year that pending home sales data was analyzed. It also happened to be a year of historically-high levels of home contract activity. Therefore, a Pending Home Sales Index reading of 100 suggests a strong housing market nationwide.

The index has read north of 90 since October 2011.

On a regional basis, February’s Pending Home Sales Index varied :

• Northeast Region: -0.5 percent from January 2012
• Midwest Region : +5.7 percent from January 2012
• South Region : -3.3 percent from January 2012
• West Region : -2.6 percent from January 2012

Mild weather may have helped the Midwest Region last month but even regional data can only tell us so much. Like everything in real estate, housing data must be local to be relevant.

Throughout the South Region, for example, the area in which contract activity fell most on a monthly basis, there are states which performed better than the regional average, and states which performed worse. Furthermore, even within those states, there are some cities which over-performed, and others which underperformed.

It’s why we can’t put too much stock in national housing news. Buyers don’t buy nationally — they buy locally.

Today’s home buyers and sellers in Charlotte , therefore, should look beyond the national Pending Home Sales Index and into local market drivers. The Pending Home Sales Index can paint a broad picture of the U.S. housing market but for data that matters to you specifically, it’s not as widely helpful. 

To get relevant, timely local real estate data, talk to a real estate professional.

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.
