THE NEW NORMAL
Smaller Universe of Buyers– 75% Fewer Housing Starts– Tighter Credit = Less Qualified Buyers– Less Compelling Reasons to Buy
You Can’t Compete on Price– Massive Inventory of Fire-Sale Homes– Massive Inventory of Homes Under Water
High-Performance Train Has Left the Station– Energy Codes on Hyper Drive– Net-Zero Home Programs
A New Technology Change Everything– Hint, it Has Nothing to Do with Housing
The best thermal imager for the money.
