Buying a home is often the biggest financial step most people take. For many, an interest-only mortgage seems attractive because the monthly payments are lower than standard repayment loans.
When the term finishes, you still owe the original loan amount, as you have only covered the interest. If you are coming to the end of an interest-only mortgage, it’s important to know your options early. Planning ahead can make all the difference. Let’s look at how these mortgages work, the rules that apply, and the choices available when you reach the end.
How interest-only mortgages work
With this type of loan, you only pay the interest each month. That means your payments are lower than a repayment mortgage, but your loan balance never reduces. For example, if you borrow £150,000, you still owe the full £150,000 at the end of the term.
This setup can work well if you have a clear plan for repaying the lump sum later, such as selling the property, using investments, or receiving an inheritance. Without a plan, the end of an interest-only mortgage can turn into a serious problem, as the lender will still expect the full debt to be cleared.

The rules about interest-only mortgages
Lenders treat these loans differently compared to repayment mortgages. They want reassurance that you have a solid plan to pay off the loan when the term ends. This is why most lenders ask for evidence of an investment, savings plan, or another repayment method at the start.
Regulations are stricter today than they were in the past. Banks and building societies must check affordability carefully. If you are coming to the end of an interest-only mortgage, your lender will usually contact you well before the final date to discuss options. Without a repayment strategy, your choices could be limited, and your home may be at risk.
What happens if you can’t pay off your mortgage at the end?
The question many people ask is simple: with an interest-only mortgage, what happens at the end if you cannot clear the balance? The truth is, you still owe the full amount, and ignoring the situation can lead to repossession.
The good news is that there are several possible solutions. Here are some of the most common routes homeowners take if they reach the end of the term without enough funds in place.
Switch to a repayment mortgage
One choice is to switch your loan into a repayment mortgage. This means your monthly payments will be higher, but you’ll start paying off the loan balance as well as the interest. This can be a good way to manage the debt if you still have enough working years left to spread the cost.
By doing this, you gain peace of mind that the mortgage will eventually be cleared. However, affordability checks will still apply, so it’s important to see if your income supports this change.
Remortgage
Another option at the end of an interest-only mortgage is to remortgage. This means moving your loan to a new deal, either with your current lender or a new one.
Some people remortgage to a repayment mortgage to start reducing the balance. Others remortgage to another interest-only deal, but lenders may be stricter about approving these. The benefit is that you might secure better rates or more flexible terms. The challenge is proving you have a reliable way of clearing the loan in the future.
Release equity
If your property has risen in value, you may be able to release equity. This means taking out a new mortgage that allows you to access some of the home’s increased worth. The funds you release can help pay off part of the existing loan.
This path can be attractive if you’ve built up a lot of value in your home but remember that borrowing more could extend the length of your mortgage and increase overall interest costs. If you are coming to the end of an interest-only mortgage, it’s worth discussing this route with your lender or broker.
Move house
Some homeowners choose to downsize when they reach the end of their mortgage term. By selling the current property and buying a smaller, cheaper home, the difference in value can be used to pay off the outstanding loan.
For example, if you owe £150,000 but your home sells for £250,000, you can pay the debt and use the remaining £100,000 to purchase a smaller property. This is a common option for people approaching retirement who no longer need a large family home.
Sell the property
Selling the property outright is one of the simplest solutions when you reach the end of the interest-only mortgage stage. The sale proceeds clear the outstanding loan, and any money left over is yours to keep.
This option may not suit everyone, especially if you want to stay in your current home. But for many, it provides a clean break and avoids the stress of carrying debt further into the future.
Extend your mortgage term
Sometimes, lenders allow you to extend the term of your mortgage. This gives you more time to arrange repayment. Extending is not guaranteed, though. It depends on your age, income, and the lender’s criteria.
This can provide short-term relief if you are not yet ready to sell or switch products. However, interest will continue to build, so you’ll need a long-term plan in place.
Can you make overpayments on an interest-only mortgage?
Yes, most lenders let you make overpayments. Even small extra payments can help reduce the final balance. For instance, paying £200 a month towards the loan alongside your interest can cut the total debt significantly over the years.
Overpayments are useful if you’re worried about what happens at the end of an interest-only mortgage, as they gradually shrink the lump sum due later.
Does an interest-only mortgage ever get paid off?
An interest-only mortgage does not clear itself. The balance remains the same until you actively repay it. Whether through savings, selling the home, or switching to a repayment plan, you must take action.
Ignoring it is not an option. Planning early helps avoid the shock of suddenly asking yourself, “What happens at the end? with an interest-only mortgage.”
Conclusion
Reaching the end of your term doesn’t have to be stressful if you plan ahead. Options like remortgaging, switching to repayment, releasing equity, or downsizing all offer solutions. The key is to act early and understand your choices. The real issue with what happens at the end of an interest-only mortgage is preparation. Acting in advance gives you more control and keeps your financial future secure.
