An interest-only mortgage is a type of home loan where you only pay the interest on the loan each month for a set period, rather than paying off the capital. This can significantly lower your monthly payments, making it an appealing option for some homebuyers. However, it comes with risks and long-term considerations that you need to be aware of.
In this guide, we will explain how interest-only mortgages work, who might benefit from them, and the potential pros and cons of choosing this type of mortgage.
How Does an Interest-Only Mortgage Work?
With an interest-only mortgage, your monthly payments are lower because you're only paying the interest on the loan, not the capital. The interest is calculated based on the loan balance, so as the principal (the amount you owe) remains the same, your interest payments stay the same throughout the interest-only period.
Typically, the interest-only period lasts for the first 5 to 10 years of the mortgage term, after which you’ll begin to repay both the capital and the interest. At the end of the term, you will still owe the original amount of the loan unless you’ve made additional repayments.
Example:
Loan amount: £200,000
Interest rate: 3%
Monthly interest payment: £500
Total loan: £200,000 (still owing at the end of the interest-only period)
The key difference between an interest-only mortgage and a standard repayment mortgage is that, with an interest-only mortgage, you don’t reduce the amount of your loan during the interest-only period.
Who Can Get an Interest-Only Mortgage?
Interest-only mortgages are not suitable for everyone. Lenders typically have strict eligibility criteria, and they may require you to meet certain financial requirements, including:
A substantial deposit: Most lenders require at least a 25% deposit, although this can vary. The larger your deposit, the more likely you are to be approved for an interest-only mortgage.
A clear repayment plan: Lenders will want to know how you plan to repay the capital at the end of the interest-only term. This could be through a sale of the property, an investment plan, or another form of repayment strategy.
Good credit history: Because interest-only mortgages are riskier, lenders generally require a strong credit rating to ensure that you can make the required payments.
If you are a first-time buyer, it may be more difficult to obtain an interest-only mortgage. Typically, these mortgages are more commonly offered to homeowners who are moving or remortgaging, especially if they already have equity in their property.
The Pros of an Interest-Only Mortgage
1. Lower Monthly Payments
The main advantage of an interest-only mortgage is the significantly lower monthly repayments, which can make it more affordable in the short term. This could be helpful if you are struggling with your monthly budget or looking to free up cash for other investments.
2. Flexibility
With lower monthly repayments, you might have more flexibility in your finances. Some borrowers use this flexibility to invest or save money, which could potentially generate returns to help pay off the principal in the future.
3. More Borrowing Power
Because the payments are lower, you may be able to borrow more than you would with a standard repayment mortgage. This might be helpful if you’re looking to buy a more expensive property or need a larger loan.
4. Better Cash Flow Management
Some borrowers use interest-only mortgages for cash flow purposes. For example, buy-to-let investors might find it more efficient to have lower monthly repayments, especially if the rental income is used to cover the interest.
The Cons of an Interest-Only Mortgage
1. No Equity Building
The major downside is that you won’t be building equity in your property during the interest-only period. Your loan balance will remain the same, and you won’t be reducing the amount you owe unless you make extra repayments.
2. Higher Overall Costs
Over the long term, an interest-only mortgage can be more expensive. While your monthly payments are lower initially, you’ll end up paying more interest overall because you’re not reducing the loan amount during the interest-only period.
3. Risk of Negative Equity
There’s a risk that property values could fall, leaving you owing more than the property is worth. This could be problematic if you want to sell the property or remortgage in the future, especially if you haven’t made any progress on paying down the principal.
4. A Large Lump Sum at the End
At the end of the interest-only period, you’ll still owe the original amount of the loan, which can be a substantial lump sum. If you haven't planned how to pay this off, you may find yourself in financial difficulty.
How Can You Repay an Interest-Only Mortgage?
Since you're not making capital repayments during the interest-only period, you need a clear plan for repaying the loan when the interest-only period ends. Here are some common ways borrowers plan to repay the principal:
Selling the Property: You may plan to sell the property at the end of the term and use the proceeds to pay off the loan.
Investment Strategy: Some borrowers set up an investment plan, such as an endowment policy or pension, to pay off the mortgage at the end of the term.
Remortgaging: If property prices have increased, you may be able to remortgage and pay off the loan through a new mortgage.
Savings: If you have built up savings during the interest-only period, you can use these funds to pay down the principal.
Is an Interest-Only Mortgage Right for You?
An interest-only mortgage can be a good option for certain buyers, particularly those who need to keep their monthly payments low in the short term or those with a clear repayment plan. However, it’s not for everyone.
Before considering an interest-only mortgage, it's important to think about:
Whether you can afford the higher payments when the interest-only period ends.
How you plan to repay the loan, especially if the property’s value doesn’t increase as expected.
The long-term costs and risks involved.
