What is an interest-only mortgage?

With an interest-only mortgage, your monthly payments are only repaying the interest on what you’ve borrowed. That means the amount you’ve borrowed doesn’t go down.

What happens to the balance at the end of the term?

When your mortgage term ends, you’ll need to pay the remaining balance in full. To pay the balance when it’s due, you’ll need to plan ahead. This is because to get an interest-only mortgage, you’ll need to show your lender how you’ll pay off the final amount.

Options for repaying an interest-only mortgage balance

Your plan to repay the mortgage balance is often called a ‘repayment vehicle’. And can include:

Savings

Save towards the final lump sum payment through a savings account.

Stocks and shares

Build up your final payment through long-term investment in Stocks and Shares ISAs.

Selling your home

Make sure you’ve considered all the practicalities. Where will you and your family live, and whether you’ll have enough money left to buy or rent somewhere else.

Selling your home can also take time and would need to be done before your final balance is due.

Pensions and endowments

Repay what you owe by withdrawing from one or more pension at the end of the term. If you’re thinking of drawing from your pension, you should speak to a financial adviser to make sure you’ll have enough money left for your retirement.

 

Other assets and properties

If you own a property, you could use the money from selling it to pay off your mortgage.

Other considerations

Changing to a repayment mortgage

Each monthly payment will then pay some of the interest and the amount you borrowed.

Make overpayments

This can be done monthly or as a one-off payment. Most lenders will let you overpay by up to 10% each year on a fixed interest rate.

Sometimes it can be higher on a variable rate.

Pros and cons of interest-only mortgages

Pros

  • Often offer smaller monthly payments as you’re only paying off the interest each month.
  • Useful for Buy-to-let property owners as your monthly rental income tends to cover the interest repayments.
  • It could give you an opportunity to save and reinvest this money into making improvements to your new property.

Cons

  • You could end up paying more in interest overall as your capital will stay the same each month. So, you’ll be charged interest on the full amount of what you borrow.
  • It might be more difficult to get accepted for an interest-only mortgage, as they’re often viewed as higher risk.
  • If you get to the end of your term and your repayment vehicle hasn’t performed and doesn’t cover the lump sum, you’ll either need to sell your home or find another way to repay.
