Quote from gnome:
My wife asked the other day, "why are they still building?". I believe it's because builders need to finish the project. If it ends up being sold in distress, a finished structure will bring a price which is greater "relative to cost" than an unfinished one.
Starting new ones now... that's different.
They're starting new ones around us. Despite tons of existing and finished unsold new homes. I can't believe the banks are willing to finance new construction, but apparently they are.
