My initial housing plan was keep doing 200k jumps. That leaves a super affordable mortgage payment while building equity. Between the ridiculous time and money required to jump houses and the tiny difference in house that 200K gets you (one extra bedroom and bathroom yippee) we made a much larger jump and dont plan on changing again for 20+ years. Debt way higher than I want, but way lower than most of my friends.There are multiple points to this.
Yes, there is a massive issue of people over extending themselves. I wouldn't put the blame on cheap credit but rather financial literacy. I'm sure we all know someone that walked into a car dealership and said I can afford $400 a month, what does that get me? Without any concept of what and how much they're actually paying.
On the other hand, there is a fairly high cost of living to be in Toronto. Your average starter condo is going for $400k, which needs a ~$80k salary to comfortably afford. This puts even financially literate people into a tight spot.
One friend was renting and just bought his first house in TO for 1.6. Crazy. They were smart renters though and had a huge pool of investments to take much of the sting off. Still, it's hard to have a reasonable debt load when a house is way more than 10x a single good income.
