Renting for 10 years and saving lots of money sounds like a great idea, but I would guess that most people that rent aren’t putting money away, they’re renting because they aren’t able to buy. If someone is renting and saving the difference, though, more power to them.
When I’m 60 or 65 years old, I would rather live in my house that’s paid off than to be paying rent, or being in year #5 of my 30 year suicide loan.
