Frequently Asked Questions
An interest-only mortgage is a loan where you pay only the interest for a set period, typically 5-10 years. During this period, your monthly payments are lower because you're not paying down the principal.
The monthly payment is calculated by multiplying the loan amount by the monthly interest rate (annual rate divided by 12). For example, a $300,000 loan at 4.5% annual rate gives a monthly payment of $1,125.
After the interest-only period, the loan typically converts to a standard amortizing loan, and your monthly payments increase significantly because you start paying both principal and interest.
