Two Big Problems with DataQuick Median Prices

In about ten days, there will be much media noise as DataQuick releases their So Cal median price figures for March.

We expect sales will be up from February, but down from March ’06. Some analysts will be surprised. Prices will be down from a year earlier, but not down nearly as much as expected from a month earlier. In fact, the median price for Orange County might actually be up slightly from February.

But it’s not really news. And it’s not even what you think it is.

It’s not news because they’ll be reporting what took place back in January and early February, when those homes that closed in March actually went into escrow, as we explained in “Market Predictions 101: Our Two Real Estate Cycles.” By the time “DataSlow” reports them, they’ll be almost 3 months old.

“DataSlow’s” median price numbers aren’t what you think because any average, median or mean (for you mathematicians), can be skewed by shifts between market segments, as was so clearly pointed in a recent statistical study by Zillow’s number-cruncher.

For example, let’s say DataQuick started reporting “median grocery prices” at your local Vons. In November, when lots of people are buying expensive items like turkeys, that median would go up. Now the prices of things might actually be down (at least in our hypothetical, if not in the real world right now. Turkey might be cheaper than it was a month earlier. But because more people were buying turkeys instead of hamburger, the median price would still go up.

Same thing in the real estate market. When there are more first time, low end, buyers the median goes down. When there are more high end buyers, it goes down.

That’s why through most of 2006 DataQuick’s median price kept moving up, even as prices in most neighborhoods were dropping. As subprime loans stated to dry up, activity was switching from the low end to the middle and higher prices. So the median average moved up, since more of the sales were in higher priced neighborhoods, even as the prices in those neighborhoods fell.

More recently, there’s been an increase in lower end sales as lenders foreclose on many subprime borrowers in starter homes, then quickly unload the property at whatever price the market will bear. Meanwhile, most high end homeowners moved up and put a substantial down payment into their home, so there are far fewer foreclosures and distressed sales in the higher neighborhoods. Instead, those homeowners for the most part have decided to just wait out the current down turn.

In 2006, DataQuick’s median price was going up while actual prices were dropping in most neighborhoods. Lately, DataQuick’s median has been dropping faster than actual prices in most neighborhoods. We believe the actual drop in So Cal home values from top to current bottom is about 25 – 30% (less in higher end areas, more in condos, starter areas, and areas with lots of new construction).

In our next post, which should be out soon, we’ll combine that last little nugget of information with our Bernanke post and our Predictions 101 post to update our own predictions.
