In the morning's second sign of strength in the housing sector, the National Association of Realtors reports that sales of existing homes rose 7.8 percent in August from July and were 9.3 percent above the pace of August 2011.

What's more, as The Associated Press reports, the adjusted annual rate of 4.82 million homes sold in August is "the most since May 2012, when sales were fueled by a federal home-buying credit."

And, says NAR:

"The national median existing-home price for all housing types was $187,400 in August, up 9.5 percent from a year ago. The last time there were six back-to-back monthly price increases from a year earlier was from December 2005 to May 2006. The August increase was the strongest since January 2006 when the median price rose 10.2 percent from a year earlier."

Our original post:

Builders started work on 2.3 percent more homes in August than in July, the Census Bureau and Department of Housing and Urban Development say.

At a seasonally adjusted annual rate, work was begun on 750,000 single-family homes, apartments and condominiums, vs. 733,000 in July.

Through the first eight months of 2012, starts have stayed above the 700,000-pace. In 2011, they only touched that level once — in November. Prior to that, the pace hadn't hit 700,000 or above since October 2008.

Of course, the pace is far below the years before the housing bubble burst in 2008. In 2004 and 2005, it was not unusual to see the rate edge above 2 million units.

We'll hear more about the housing sector later this morning when the National Association of Realtors reports about sales of existing homes in August.

Meanwhile, The Washington Post and The New York Times' Deal Book blog report that mortgage rates, which are already down around 3.55 percent for a 30-year loan, could be below 3 percent if banks weren't holding back.
