I would wait two years and see the builders squirm.
The developers lie just to make a sale and to give a potential buyer a sense of urgency. A friend recently asked me to visit a Del Sur development with them. The sales agent said that all the houses are sold out, blah, blah, blah. It turns out there are plenty available. Same story everywhere.
You guys who are shopping for new houses, visit a development today, make notes of everything. Then return 2 months from now to see if there are any changes. That will tell you the direction of the market.
