What the lower payment is worth
Take a $300,000 loan at the October 8 rates, for a buyer who qualifies with the lender, paid on schedule with no refinancing or extra payments. The 20-year’s principal and interest payment, before the points and other charges, is about $2,215 a month, against $2,530 on the 15-year.
That’s about $315 less a month, with nearly identical points, 1.671 against 1.674. Its scheduled interest, though, comes to about $232,000 against $155,000 on the 15-year, about $76,000 more.
