According to The Canadian Real Estate Association, the price of an average resale home hit a record $303,836 in May 2006, up a stunning 12.9% from the year-ago period. The hottest markets were out west with Vancouver up 24%, Calgary up 44% and Edmonton (Go Oilers! Go!) up 23%. The increase was much more sedate in Toronto (up 5.5%), Ottawa (up 4.8%) and Halifax (up 7.7%).

I wonder if the price appreciation in the Western markets is sustainable. Take Calgary, where an average house costs $358,000. Even assuming a traditional down payment of 25%, the monthly mortgage payment (on a $268,500 mortgage, 5-year 5.35% fixed rate, amortized over 25 years) would be $1,616. That’s just the mortgage. Adding property taxes, insurance, heating, hydro, water and sewer and maintenance could easily push housing expenses to $2,500 per month. An annual income of $90,000 would be needed just to qualify for the mortgage (assuming no other loan payments). How many average households can really afford the average house?
