Earlier quoted context omitted.
Folks just need to try and live below their means. This may not be practical for everyone, obviously. I bought a town house condo right before I turned 25, worth roughly 2x my salary at the time. By age 31, I had paid it off entirely: a 15 year mortgage, done 8 years ahead of schedule. Could I have done better if I invested that money? Probably. But I like being debt free. I also invested a ton anyway.
Of course it's easy to buy when properties are only twice your salary and can be fully paid off in a couple of years. You were just lucky to leave when properties were cheap and interest were high.
I know people who bought homes at similar times who have refinanced every 3 years and now owe way more than they started with. They don't care about debt. They continue to spend more than they make, year after year, live pay check to pay check despite their high salaries...
