"renting is always taking money out of your pocket and putting it into somebody else's."

If you're paying for a mortgage, then what difference does it make if it's your mortgage or your landlord's mortgage? The obvious difference it makes is whether you're on the hook if the value of the property goes down, which is an argument against owning.

Owning makes sense if you can avoid borrowing, but that means saving for many years and spending a fraction of what most people do.
