In a word: UP!
Take a look at the chart and see for yourself. The blue line at the top of the chart is 2013.
The August 2013 dollar volume of $2.192 billion was the 2nd highest month ever in DFW ( after July 2013). It is up 29% over this time last year. Actual prices aren't up 29%, but the dollar volume of sales is up that much. We are selling more homes and the prices are up a bit as well.
These stats are from the North Texas Real Estate Information Systems and the chart is created by Hexter Fair Title.
