Think this through with your own numbers but without time swapping the fertility rates across generations. (Suddenly having a house means we're going to pump out 4 kids? Holy bold assumptions Batman!)

Say a condo at 800 feet, 800 / 3 = 266.

Even a small house, 1500 / 3 = 500.

Heck, even if we double the fertility rate for folks in a small detached home, you're still ahead:

1500 / 4 = 350.

I did the math on a condo project in Vancouver (not even in downtown, just in the City across the bridge) the land cost for each unit they were building was $300,000. That number alone makes them unaffordable, before even talking about the construction costs.

Yeah, so essentially some of the most expensive real estate in the country, no doubt it's going to be more expensive. That's why you have to build condos there not detached homes. Try putting a detached home there. Do that and the house is suddenly what, tens of millions?

In this case, you're effectively saying that because we build condos where it is too expensive to put detached homes, condos are more expensive? That's some pretty silly logic there.
