A FEW Key Points:
1) There is a clear seasonal pattern for house prices.
2) The surge in distressed sales during the housing bust distorted the seasonal pattern. This was because distressed sales (at Lower Price Points) happened at a steady rate all year, while regular sales followed the normal seasonal pattern. This made for larger swings in the seasonal factor during the housing bust.
