We built our house in 2009 in Waco, TX.The inspection before the recent sale of our home revealed two problems.
First, there is no back-flow valve on the garbage disposal, second there is a screen on the dryer vent on the roof which catches lint. We have no way of checking or cleaning that screen and we must have a different type installed for the new owners. The inspector was surprised that our dryer worked at all well as it was clogged.
Other than that he could find no problems.
All in all a pretty good report, but I think you should get your own inspector before settling on your DR Horton home.
