Interest-only mortgages typically allow borrowers to make payments only on the interest for a set initial period, usually lasting between 5 and 10 years. After this period, the loan transitions to a fully amortizing structure, requiring payments on both principal and interest, often causing a significant increase in monthly payments.
The option of making interest-only mortgage payments will generally last between three and 10 years. After the interest-only payment period ends, you will then have to make principal and interest payments, which means your monthly payment will increase, regardless of whether the interest rate stays the same or changes.
The 3-7-3 Rule in mortgages isn't a loan type but a federal timeline from the TILA-RESPA Integrated Disclosure (TRID) rule, ensuring borrower protection by mandating disclosures within 3 business days of application, a 7-business-day wait between the initial Loan Estimate and closing, and another 3-day wait if significant changes (like APR) occur, giving borrowers time to review costs before committing to a loan.
Some lenders can extend interest-only mortgages by up to 20 years. The lender will need to assess your income, credit history, and repayment vehicle again to make sure you can make the final payment later.
You may choose from payment options including: Interest-only payment. Minimum payment not including all interest due. Full principal and interest payment based on the remaining scheduled term of the loan or on a 15-year or 30-year term.
👎 Drawbacks of Interest-Only Mortgages
With interest-only, you're only paying to borrow, not own. So, unless the market adds value to your home, you won't be building any equity. If prices drop, you could even end up owing more than your home's worth – a bit like paying rent but with a big bill waiting at the end!
An interest-only mortgage payment on $200,000 depends on the interest rate, but at 5%, it's around $833/month (just interest), significantly lower than principal & interest payments, though you never build equity and pay more total interest over time, with later payments including principal. For example, at 3.25%, the initial payment is about $542/month for the interest-only period.
Yes, you could switch some or all of your interest only mortgage to a repayment mortgage (also known as a capital repayment mortgage) if this is suitable for you and you meet our criteria. We will not charge you a fee to do this, although you will see an increase in your monthly mortgage payments.
If you'd like to reduce your balance before your mortgage term comes to an end, you could make regular or lump sum overpayments. And if your initial period has ended (which could have been a fixed or tracker rate), you can overpay without paying an Early Repayment Charge.
Interest-only repayments
Once the agreed interest-only period ends, you'll start repaying your principal at the current interest rate at that time. As you're not making payments on the 'principal', this will remain the same, unless you choose to make additional repayments.
You'll need to be well-qualified to be approved for an interest-only mortgage. Banks generally look for borrowers who have: A credit score of 700 or more. A debt-to-income (DTI) ratio of 43 percent or less.
Repayment plans
At the end of the interest-only period, the loan will change to a 'principal and interest' loan. You'll start repaying the amount borrowed, as well as interest on that amount. That means higher repayments.
Switch to a repayment mortgage
If you have sufficient time before your interest-only mortgage ends, ask your lender to switch it to a repayment mortgage. This will increase your monthly payments but endure that the balance is repaid at the end of the term.
Disadvantages
For a $150,000 mortgage over 30 years, your principal and interest payment is roughly $900 to $1,000 per month, but this varies significantly with the interest rate, such as around $900 at 6% or $998 at 7%. Remember this doesn't include property taxes, homeowner's insurance, or potential Private Mortgage Insurance (PMI), which add to the total monthly cost.
To pay off a 25-year mortgage in 10 years, you need to make significant extra principal payments through strategies like increasing monthly payments, making bi-weekly payments (effectively one extra payment a year), applying windfalls (bonuses, refunds) as lump sums, or refinancing to a shorter term, focusing on early payments to maximize interest savings.
The average age to pay off a mortgage in the U.S. is around 62, with many becoming mortgage-free in their early 60s, coinciding with or just after typical retirement age, though figures vary by source. While some financial experts suggest paying it off by 45 for aggressive investing, data shows a significant portion of homeowners, especially older ones (60+), are mortgage-free, but increasingly, older adults (60s, 70s, 80s) carry more mortgage debt than previous generations, according to Marketplace.
