Q1: What is an interest-only period?
A: An interest-only period is a specified timeframe during which the borrower pays only interest, typically ranging from 1-10 years before principal payments begin.
Q2: What happens after the interest-only period ends?
A: After the interest-only period, the loan converts to amortizing payments where both principal and interest are paid, resulting in higher monthly payments.
Q3: Are interest-only loans common?
A: Interest-only loans are commonly used for mortgages, business loans, and certain types of personal loans, particularly when borrowers want lower initial payments.
Q4: What are the risks of interest-only loans?
A: The main risk is payment shock when the interest-only period ends and payments increase significantly. Also, the principal balance doesn't decrease during this period.
Q5: Can I pay principal during the interest-only period?
A: Most interest-only loans allow voluntary principal payments, but they're not required during the interest-only period.
