Yes and the interest rates in 1980 were such that the mortgage P&I payments on a 1980 mortgage were $1106 per $100K borrowed vs $422 per $100K @ 3% today.

65K borrowed in 1980 cost $719/mo. 320K borrowed today costs $1349/mo (both are principal and interest only).

$719 in 1980 is $2258 in 2020.

Yeah the "whats my monthly" being about the same doesn't quite capture what's happening though.

Compare what happens when you get a raise or a small windfall and try to pay your mortgage off early.

I'd pick "small amount, high interest" over "massive amount, low rates" if that were an option.

That option requires governments to not be printing massive amounts of money, though.

I am planning to refinance again (back to a 30-year mortgage) and won't be in any hurry whatsoever to pay it off early. Borrowing money at 3% nominal with the (hopeful) prospects of economic growth allowing inflation to return means that I expect/hope to be borrowing that money at negative real rates in the back half of that loan.
