DALLAS (Dallas Morning News) – North Texas home builders posted more conservative home start numbers in 2009 than in previous years, but some still fared well.  Overall, builders started about 13,500 homes in the area last year, a more than 70 percent decrease from the market’s peak in 2006.  The 20 largest builders built 17 percent fewer homes in 2009 than in 2008.  Fort Worth–based D.R. Horton Inc. increased its starts by 20 percent between 2008 and 2009, building about 2,289 homes last year, according to Residential Strategies Inc. However, this was less than half the number of homes the builder started in 2006.  The next three largest builders — Pulte-Centex, Highland-Huntington and Meritage-Legacy — reduced their starts in the DFW area in 2009.
