The index data, released Tuesday, showed home sale prices climbing 10.2 percent in March from a year earlier. However, another index by Lender Processing Services, Inc. found that prices rose over this same period by 7.6 percent.
To be sure, record low mortgage rates are bringing out a lot of home buyers, increasing home sales and boosting prices. But a large proportion of these purchases are from well-capitalized real estate investors, picking up relatively inexpensive properties to rent, until the home values rise because of growing demand.
That suggests that rising home sales do not reflect a truly large base of ordinary homebuyers, some of whom now own homes that are under water and have little or no equity to use for another down payment on a new home purchase.
Even with the rising home prices in the first quarter, 44 percent of American homeowners were holding mortgages that were greater than their home was worth, according to the Negative Equity Report published by Zillow, the widely-read real estate website.
Their report showed that 25.4 percent of homeowners were entirely underwater, and that another 18.2 percent were "effectively" underwater because their equity would not produce 20 percent down payment for another home.
Then there is the "bubble" factor. Home prices are rising from rock bottom levels after the crushing housing debacle in 2008. Left out of most euphoric home sales reports is the fact that home prices were still well below their 2006 highs by at least 28 percent.
Missing from all the hype about rising home purchases is this stunning factor: U.S. homeownership is at its lowest rate in years and is shrinking.
"An estimated 91,000 U.S. homeowners became renters since the start of 2012, a decrease that pushed America's homeownership rate to its lowest level in 18 years, a U.S. Census report shows," according to the Real Estate Blog website.
"Sixty-five percent of Americans owned their homes during the first quarter, compared to 69.2 percent in 2004," the Blog reports.
In other words, the U.S. housing industry still has a long way to go before it will have a significant growth impact in a $17 trillion economy.
Still, home sales are rising, although there will be ups and downs in their overall numbers in the months to come. Whether the upward rise in sales and prices remains to be seen. There are still many obstacles ahead in the Obama economy that can undermine future home sales.
Federal Reserve Board Chairman Ben Bernanke has been suggesting lately that the Fed may begin raising its near-zero interest rates in the future, pushing mortgage rates beyond the reach of many Americans.
High unemployment still looms over the economy at 7.5 percent, and the latest mediocre jobs figures suggest we are not going to see major changes on that front anytime soon.
The Obama economy produced only 165,000 jobs in April, far below what is needed to bring the jobless rate down to more normal levels in the next several years.
So it's a little premature to be popping champagne corks on the basis rising home prices. This is an economy that is still in recovery.
