My thoughts:
1. Coming out ahead vs at a loss depends, as has been noted, on timing. I was one that lucked out with timing. Not everyone has been or will be.
2. I do know people who've gotten to renovate their rented home to what they want. They rented super cheap, renovated to their heart's content, and continue renting cheap. Landlord is happy because the place is improved, and is being well looked after. Tenants are happy because they have their dream space for cheap. Yes, landlord can end the tenancy with (limited) legal reasons, but so can factors end homeownership. In my case, horrible tenants, skyrocketing property insurance rates (with no claims), skyrocketing property tax rates, etc. In other people's cases, divorce, job loss, disability requiring different amenities, etc. Ownership is not much more guaranteed than renting. On the flip side, ownership can crunch a life, if we end up underwater on a mortgage or real estate stalls for years (my parents bought their dream house, filled it with kids, and then couldn't sell it for 10 years when they needed to).
3. Emotional reasons... I'm going to say this is not a simple factor. Emotions change. Life needs change. I bought my house for emotional reasons -I planned to fulfill my secular vocational dreams through it, then parent in it, then retire in it. I loved that house. Most of my life changed, and I let the house go. I'm happy I fulfilled that dream, happy that the timing made me money, and happy I was, logistically speaking, able to move on when life continued to morph.
It's a very, very narrow situation in which I would own in Canada again. (I rent very happily.)
