Another way to gauge prices

An interesting article in Yahoo Finance about US house prices. While this is the US, I believe that the metric should apply to Canadian markets/prices as well.
What do you think?

To gauge house prices

Someone needs to link the article of future pricing often determined by 50% factors and 50% randomness

Its a good read but not applicable to many markets - wouldn`t there be a ton of factors to look at to determine its relevancy to a particular market?
