Frequently Asked Questions
How much lower is an interest-only payment?
On $200,000 at 6.5%, interest only is $1,083.33 a month versus $1,264.14 for a 30-year amortizing loan, a gap of about $180.80.
What happens when the interest-only period ends?
Payments reset to repay the principal over the remaining term, which is shorter, so the new payment is higher than a loan that amortized from the start.
Does the balance go down on an interest-only loan?
No. Every payment covers only the interest, so after any number of interest-only months you still owe the full original principal.
