I paid 140k for a condo a couple months back. Great location, super old building.
I currently pay less for my mortgage + condo fees + utilities than I did while renting. I invest the surplus primarily in XEQT for broad market exposure. I have no expectation of selling the unit for more than I paid, since condos are depreciating assets.
I think the issue I take with this guy's perspective is that he doesn't present it as "I overpaid for a condo and was surprised when it went down in value", but rather that renting is more financially sensible than buying. The math shakes out differently for everyone, and there is no "best" way to pay for the place you live.
