A: Area after Dufferin on King West is considered Parkdale (to the north), not sure to the South. This is a very mixed neighbourhood but few condos (actually, none that I can think of) and low prices will be there for some time. Great place to develop I'd think.
A: $400 is not a risky psf. I'd say that around $450-500 is correct for West of Bathurst, south of Bloor, $375-450 east of Parliament, s of bloor, and $5-600 for downtown core. The non-luxury condo's that are currently selling for $7-800 (Casa, Ice, Maple Leaf) will probably drop a good 20% or more over the next 2 years back down to the range above, or stagnate for a good long while while everyone else catches up IMO.
A: We're all just giving educated guesses, but I'd say later in the year and even better into the middle of next year. I'd guess you'd have another 10 000 condos alone to look at and with the C$ expected to reach parity and bond markets going nowhere fast, historically low interest rates will still be around.
