Case Shiller and Teranet both released data for May 2009 last week and I have compiled / updated some charts to display this data.
The first chart shows the monthly percent price change in selected cities. What I would note here is the clear seasonal effect on price movement. Prices are more likely to increase in the spring and summer and more likely to decline in the fall and winter.
I recalculated the Teranet and Case Shiller Indices to show the same base date in 2000 so we can view the results of the boom and bust in the US and Canada in a comparable way. It is amazing to me how high prices got and how far they have fallen in some places - almost back to pre-boom levels.
The last chart is the now well known price decline from peak chart. I added Calgary upon request from some regular readers from Calgary. The smoothing (3 month moving average) that takes place in the Case Shiller and Teranet data really makes a big difference in how peaks and price changes are displayed.
