Yossi,
I completely agree with your assessment of a good investment. My issue with a project like Casa is endemic to the entire pre-construction condo industry in Toronto and how they've fundamentally changed the way they do business in the past 2-3 years as opposed to anytime prior.
If you bought a condo as late as, say, 2006, you would pay the current market price for that condo because you were the person taking a RE gamble that when it was finally built it wouldn't be worth less and might be worth more. If you bought in 2006 for a condo to be finished by 2009, you were still paying the 2006 condo market price.
What has happened over the past 3 years is that the developer's have changed their pricing strategy - which might be why new condo sales are down 40% from 2008 and 50% from 2007 - and are now trying to sell not what the condo is worth now, in 2009, but what it might be worth when it's built. So not only is the buyer still making an RE gamble, but the possible payoff for taking that gamble has been stripped away by the developers. CASA is an example of this. There is absolutely no way when it is complete that it will get $870/ft. It might get $6-$700.
With all the condos being completed in the next 18 months in the core (15 000), plus 5-8 luxury condo towers being completed in the next 3 years, there will be little to no price growth. CASA is not even a luxury building. Not even in their wildest dreams would someone purchasing this see any appreciation within the next 6 years and by then it will need some serious updates adding more expense to their bottom line. And no appreciation is actually depreciation when inflation, even of 1 or 2% is factored in.
