Well here is some spin from Centex homes. I just got it in my morning email.

“Time is running out to take advantage of purchasing a new home from Centex Homes-Inland Empire. Beginning Monday, October 2, prices on our homes will increase by up to $20,000. Take advantage of the best prices by visiting your preferred new home community and purchasing today!”

The 20k increase will probably be caused by the Honda Civic hybrid they will have to add as an incentive for you to drive that far every day.
