Earlier quoted context omitted.
If you watch interviews of people who went the tiny house route, a lot of them started with "why do I need to be in debt (mortgage) for 30-40 years of my life?". There is a growing movement of people rejecting being in debt for decades and that is really a good thing. And if moving into a tiny house is carefully done, then it doesn't need to be lower standards of living.
> why do I need to be in debt (mortgage) for 30-40 years of my life Because you're (hopefully) going to come out of the other side of those 30-40 years, regardless. In one case, you can have a house you own free and clear. In the other case, you're still paying rent to someone else. And 30-40 years is the extreme. Paying just a little extra principal every month you can have the loan paid in well under 30 years.
If you pay off your loan you are debt free in 30 years or less. However many people don't: they see their house go up in value and take out a bigger loan to spend now.
