Why Interest Only Mortgages Could Work for You
Interest-only mortgages remain a valuable option for the right borrowers, particularly buy-to-let landlords and high earners who meet stricter lending criteria. With professional guidance ensuring suitability and mortgage repayment planning, these mortgage types can offer significant advantages:
Lower Monthly Payments
Interest-only mortgages typically have lower monthly payments than equivalent repayment mortgages because the monthly payment covers only the interest charged on the loan, rather than both the interest and the capital balance. This can improve cash flow and increase affordability for some property investors or high-net-worth clients. However, as the original loan balance remains outstanding throughout the mortgage term, it is important to have a suitable repayment strategy in place to ensure the loan can be repaid at the end of the term
Cash Flow Flexibility
Due to lower monthly payments, interest-only mortgages can improve affordability and financial flexibility for borrowers, freeing up funds for property improvements or other investments.
Buy-to-Let Advantages
Interest-only mortgages are often considered a valuable option for buy-to-let landlords, as they allow landlords to keep monthly payments lower while using rental income to cover costs and save for the capital repayment later.
Investment Opportunities
Freed-up capital can be directed into investment funds, ISAs, pensions, or investment bonds, potentially increasing your overall wealth.
Increased Borrowing Power
Interest-only mortgages can potentially increase borrowing power as lower monthly commitments may allow borrowers to afford more expensive properties.
It is essential to have a repayment strategy in place for an interest-only mortgage, as the borrower will owe the full amount borrowed at the end of the mortgage term. Our financial adviser team ensures every client has a suitable plan before proceeding.
Our Interest-Only Mortgage Services
First-Time Buyers and Home Movers
Interest-only mortgages are subject to stricter lending criteria than standard repayment mortgages and are not suitable for every borrower. Many lenders require a minimum level of equity in the property or a maximum loan-to-value (LTV) threshold before considering an interest-only application. Additional requirements may also apply, such as minimum income levels and a credible repayment strategy to repay the mortgage balance at the end of the term.
For some borrowers, a part-and-part mortgage may provide a suitable alternative. With this arrangement, part of the mortgage is on a repayment basis, and part is on an interest-only basis. This can help reduce monthly payments while also meeting lender requirements regarding equity levels, loan-to-value ratios, or repayment planning.
Our specialist advisers can help you understand whether an interest-only mortgage, a repayment mortgage, or a part-and-part arrangement is most appropriate for your circumstances and long-term financial goals
Interest-Only Remortgages
An interest-only remortgage may be suitable for homeowners looking to reduce monthly mortgage payments, improve cash flow, or access equity from their property for other purposes. Depending on your circumstances, releasing equity through a remortgage could provide funds for home improvements, property purchases, debt consolidation, or other financial objectives.
Many homeowners approaching the end of an existing interest-only mortgage term are concerned about how the outstanding balance will be repaid. In some cases, lenders may be willing to extend the mortgage term, subject to affordability, age limits, lending criteria, and the suitability of the proposed repayment strategy. Alternative solutions may also be available, including switching to a part-and-part arrangement or moving some or all of the borrowing onto a repayment basis.
Our advisers can assess your options, explain the available solutions, and help you find a suitable strategy based on your individual circumstances and future plans.
Buy-to-Let Investors
Many lenders accept interest-only mortgages for buy-to-let properties, which is not the case for all types of mortgages, making it a unique option for property investors. With an interest-only mortgage, landlords only pay the interest on the loan during the mortgage term, meaning they will owe the full capital amount at the end of the term, which requires a repayment strategy.
Interest-only mortgages can be particularly beneficial for buy-to-let landlords, as they can use rental income to cover interest payments and save profits to repay the capital at the end of the mortgage term.
We offer portfolio landlord solutions, commercial lending options, and detailed rental yield calculations to support your investment plan.
Top 10 Common Interest-Only Mortgage Repayment Strategies:
When applying for an interest-only mortgage, lenders will typically require borrowers to demonstrate a credible strategy for repaying the outstanding mortgage balance at the end of the mortgage term. The repayment options accepted vary between lenders and are subject to their individual lending criteria. Commonly accepted repayment strategies may include:
Property Sale
Selling the mortgaged property at the end of the mortgage term. Many lenders will require sufficient equity to remain in the property and may apply maximum loan-to-value limits. Up to 75% LTV with minimum equity requirements; relies on house prices maintaining or increasing value.
Pension Lump Sum
Common repayment vehicles include taking a tax-free lump sum from a pension at retirement, from both defined contribution and benefit schemes. Lenders will typically consider the projected pension value and retirement plans.
Investment ISAs
Investments held within a Stocks and Shares ISA may be accepted by some lenders, subject to minimum values and investment performance assumptions.
Endowment Policies
Existing policies with projected maturity values offering a lump sum at the mortgage end date
Unit Trusts and OEICs
Investment funds may be accepted as a repayment vehicle by some lenders, depending on the value and type of investment held.
Investment Bonds
Certain investment bonds may be considered as part of a repayment strategy where lender criteria are met.
Sale of Second Property
Equity held in another residential or investment property may be used as the intended source of repayment. Additional UK property equity up to 75% can cover the remaining capital owed
Cash Savings
Savings held in bank or building society accounts can often be used where sufficient funds are available to repay the mortgage balance.
Part-and-Part Mortgage Arrangements
Rather than relying entirely on a future repayment vehicle, some borrowers choose a part-and-part mortgage, where part of the borrowing is repaid during the mortgage term, and part remains on an interest-only basis.
Business Sale
Sale of business assets or equity stakes, providing one lump sum for mortgage repayments
Important Considerations
The suitability and acceptance of any repayment strategy will depend on the lender's criteria and your individual circumstances. Interest-only mortgages are not suitable for everyone, and borrowers should carefully consider how the outstanding capital balance will be repaid at the end of the mortgage term.
Investment Warning: The value of investments can fall as well as rise and may be worth less than originally invested. Future investment performance is not guaranteed and may not generate sufficient funds to repay the mortgage balance.

Our Interest Only Mortgage Process
Initial Consultation
Our initial, comprehensive assessment examines your financial circumstances, goals, and the combined joint income of all applicants. To be eligible for an interest-only mortgage, you must meet a specific lender's requirements. We review repayment strategy options against lender requirements, conduct affordability calculations, and discuss loan-to-value implications. Interest-only mortgages are generally only available for loans that are less than 75% of the property’s latest valuation, with stricter limits for certain repayment plans. Some lenders have minimum income requirements and are only able to accept certain repayment strategies.
Repayment Plan Development
Evidence gathering for your chosen repayment vehicle is critical. Lenders often require a much larger deposit (typically 25% to 50%) and higher minimum income requirements for interest-only mortgages. We analyse lender-specific requirements, assess risks, and develop backup plan recommendations. Interest-only mortgages can be seen as riskier by lenders because they require a repayment plan to cover the capital at the end of the term, which may include investments or the sale of the property.
Application and Agreement in Principle
With whole-of-market access to different providers, we select the most suitable lender and submit your application. Our team provides documentation support and progress monitoring, typically securing an agreement in principle within 48 hours. Interest-only mortgages typically require that the mortgage term ends before the borrower turns 70 years old—we ensure all eligibility criteria are met before submission.
Completion and Ongoing Support
We liaise with solicitors and coordinate completion, ensuring a smooth transition to your new property or remortgage arrangement. Many borrowers with interest-only mortgages should take control of their repayment planning now to ensure they can repay the outstanding balance at the end of the term. Our regular reviews help you monitor your repayment vehicle performance. Options for repaying an interest-only mortgage include switching to a repayment mortgage, making overpayments, or using an investment plan to cover the capital at the end of the term.
