I would agree with the comment that Centex is releasing at a lower price in order to get the project going strong. Existing projects have limited opportunity to lower prices lest they get sued by previous phase buyers. That’s exactly what happened in 1990 when builders lowered prices by 20%. People were putting “for sale” signs on their houses to scare off buyers and punish the builder (they also hurt the resale value of their own houses)
I suspect that other upcoming projects will have lower starting prices.
