    What is an Interest Only Mortgage?

    An interest-only mortgage is a loan with monthly payments covering only the interest, with repayment of the capital sum due at the end of its term. Since your capital balance won’t decrease over time, an effective plan must be in place to repay it at the end of the term.

    Why Santander is a Top Choice for Your Interest-Only Mortgage

    Santander provides comprehensive support and tools for those considering interest-only mortgages, ensuring customers are well-informed and supported throughout their mortgage journey.

    Features of Santander Interest Only Mortgages

    Santander’s interest-only mortgages come with features designed to help homeowners manage their finances more effectively.

    Basics of Interest Only Mortgage Payments with Santander

    With Santander’s interest-only mortgage, you pay towards the interest each month. It’s crucial to have a repayment plan in place to settle the capital by the mortgage’s conclusion.

    Benefits of Monthly Payments for Existing Santander Customers

    Existing Santander customers can switch to interest-only payments for a period, potentially without impacting their credit score, providing financial flexibility when needed.

    Understanding the Interest Only Mortgage Balance

    The mortgage balance remains unchanged with interest-only payments. Santander offers advice and resources to help manage and eventually repay this balance.

    Understanding Buy-to-Let Interest-Only Options

    Buy-to-let investors often select interest-only mortgages as an effective means of managing cash flow and unexpected expenses. In this arrangement, landlords only pay interest monthly while the principal amount must be repaid upon expiration. It can be particularly useful in managing cash flow as lower monthly outgoings provide a cushion against property maintenance or unexpected costs; while tax advantages exist since mortgage interest payments are often tax-deductible against rental income.

    Risks and Considerations of Interest Only Mortgages

    Interest-only mortgages can offer lower monthly payments but come with risks, such as the potential for negative equity and the need for a robust repayment strategy.

    The Risk of Negative Equity

    The risk of negative equity is more pronounced with an interest-only mortgage, as the property value could fall below the mortgage balance due to the capital not reducing over time.

    Interest Amount Considerations

    Interest rates on interest-only mortgages may be higher, and though monthly payments are lower, the total amount of interest paid over time can be more significant.

    Planning and Managing Your Interest-Only Mortgage with Santander

    Choosing an interest-only mortgage requires careful consideration and strategic planning. Santander provides a range of options to ensure that you are well-prepared for the repayment phase of your mortgage.

    Importance of Regularly Reviewing Your Mortgage Payments

    It’s essential to keep a close eye on your mortgage repayment plan:

    • Assess Investments: Ensure that any investments linked to your mortgage are performing as expected.
    • Adjustments: Be prepared to adjust your repayment strategy if your investments are underperforming or if your financial situation changes.
    • Check Terms: Understand the terms of your mortgage product regarding overpayments and early repayment charges to take advantage of any opportunities to reduce your balance without incurring additional costs.

    Considering the Overall Mortgage Deal Cost Comparison: Interest-Only vs. Fixed Rate

    When evaluating mortgage options, consider the long-term financial impact:

    • Interest-Only Mortgages: Typically have lower initial monthly payments, but since the capital isn’t being reduced, the total amount of interest paid over time can be higher.
    • Fixed-Rate Mortgages: A Santander Fixed Rate Mortgage offers the security of consistent monthly payments and the benefit of reducing the capital balance alongside the interest, which may result in a lower total cost over the mortgage term.
    • Cost Analysis: Use mortgage broker tools and calculators to compare the total cost of borrowing between interest-only and fixed-rate mortgages, taking into account interest rates, fees, and the term of the mortgage.

    Strategies for Repaying Your Interest Only Mortgage Balance

    Santander encourages borrowers to have a solid plan for repaying the mortgage balance by the end of the term. Here are some strategies they offer:

    • Savings and Investments:
    • Property Sale
    • Overpayments
    • Switch to a Repayment Mortgage

    Below we delve deeper into having a solid repayment plan with your interest-only mortgage.

    Santander Interest Only Repayment Plan

    When it comes to the conclusion of your interest-only mortgage with Santander, having a viable repayment plan (repayment vehicle) is crucial. Whether you’re a year away or have up to 15 years remaining, it’s essential to have a strategy in place to repay the mortgage at the end of its term. Below are several options you might consider.

    Switch to a Repayment Mortgage

    Transitioning to a repayment mortgage involves changing your existing mortgage to one where you pay back both the interest and the capital. This option will likely increase your monthly payments, but Santander is committed to ensuring any new arrangement is affordable within their lending criteria.

    Savings and Investments

    For those whose repayment plan is tied to savings and investments, it’s important to regularly review these to ensure they will adequately cover the mortgage capital at the end of the term. These investments might include endowments, pensions, or cash/share savings such as ISAs. If there’s a risk they won’t cover the full amount, it’s advisable to consult an independent financial adviser.


    Making overpayments is a straightforward way to reduce the capital balance of your mortgage. Depending on your mortgage terms, you may be able to make overpayments without incurring early repayment charges:

    • If your mortgage has early repayment charges, you can typically repay up to 10% of your loan balance each calendar year without a charge.
    • If your mortgage does not have early repayment charges, you can make unlimited capital repayments without additional costs.

    Selling Your Home

    Selling your property to repay your mortgage at term’s end is another option. However, several factors need consideration:

    • After selling your current home and settling your mortgage, will the remaining funds be sufficient to purchase a new home in your desired location?
    • If the equity from the sale isn’t enough for another home purchase, renting might be the next viable option.
    • Consider whether you are prepared to move out of your home and if the timing aligns with your mortgage’s end. Also, evaluate if your home will be marketable when you plan to sell.

    It’s important to weigh these options carefully and consider your personal circumstances and future plans when deciding on the best repayment strategy for your Santander interest-only mortgage.

    Understanding Santander’s criteria is essential when considering an interest-only mortgage. Here’s a detailed look:

    Santander does not have a minimum income requirement for borrowers looking for interest-only mortgages. However, the minimum borrowing amount is £100,000 and the maximum is £3,000,000.

    How Will You Pay Back? (Repayment Strategy)

    Borrowers must have a repayment strategy in place to repay the capital at the end of the interest-only period. This strategy can include selling the property, using savings or investments, or a Santander remortgage. Santander will assess the borrower’s repayment strategy and may require proof of savings, investments, or pension income.

    How Long Can Your Mortgage Last? (Eligibility & Loan Terms)

    The term of the mortgage can vary, but it’s important to note that any change you wish to make to your borrowing is subject to status and Santander’s lending criteria.

    How Much of the Property’s Value Can You Borrow? (LTV Limits)

    The loan-to-value ratio (LTV) cannot exceed 70%, meaning the borrower must have a minimum deposit of 30%.
