What are the typical fees associated with a Retirement Interest Only mortgage?

13th February 2026

By Simon Carr

A Retirement Interest Only (RIO) mortgage allows homeowners in retirement to pay only the interest on their loan monthly, with the capital repaid upon death or moving into long-term care. While offering affordable monthly payments, RIO mortgages involve various upfront and ongoing costs, including arrangement, valuation, legal fees, and potential early repayment charges (ERCs).

What are the typical fees associated with a Retirement Interest Only mortgage?

A Retirement Interest Only (RIO) mortgage is a specific type of later life lending product designed for borrowers who are already retired or approaching retirement. Unlike standard mortgages where the term ends at a specific date, a RIO mortgage runs until a defined life event occurs, usually the death or long-term care admission of the borrower(s). Understanding the total cost of borrowing requires looking beyond the monthly interest payment and considering the full spectrum of associated fees.

The fees associated with a RIO mortgage fall generally into three categories: upfront costs, ongoing costs, and exit costs.

Upfront Fees: Initial Costs to Secure the RIO Mortgage

The application stage requires several non-refundable fees that cover the administrative process and due diligence required by the lender. These costs must be factored into your budget, as they are typically payable whether or not you proceed with the full loan.

1. Arrangement or Product Fees

This is often the largest single upfront charge. It covers the costs incurred by the lender for setting up and administering the mortgage account.

  • Structure: Arrangement fees can be a fixed monetary amount (e.g., £995 or £1,499) or a percentage of the total loan amount.
  • Payment Options: While some lenders require this fee upfront, it is often possible to add the arrangement fee to the loan balance. However, if you choose to add it to the loan, you will pay interest on the fee itself over the lifespan of the mortgage, increasing the overall cost significantly.

2. Valuation Fee

Lenders require an independent professional valuation of the property to confirm its market value and suitability as security for the loan. The size of the valuation fee generally depends on the value and size of your property.

  • Purpose: This protects the lender by confirming they are not lending more than a prudent percentage of the property’s worth (the Loan-to-Value, or LTV).
  • Cost Variation: For properties of standard value, this may be a few hundred pounds, but it increases substantially for high-value or unusual properties.

3. Legal and Conveyancing Fees

Solicitors or conveyancers are essential for handling the legal transfer of funds, registering the charge against the property, and ensuring all title deeds are correct. Since RIO mortgages often involve considerations of estate planning and future repayment triggers, legal advice is mandatory.

  • Independent Legal Advice (ILA): Unlike standard residential mortgages, RIO and other later life lending products typically require borrowers to seek ILA to ensure they fully understand the implications of the loan, especially concerning how the capital will eventually be repaid (often via property sale).
  • Disbursements: These legal fees also cover disbursements, such as Land Registry fees and local authority search costs.

4. Broker or Advice Fees

Many RIO mortgages are complex products and are generally accessed via specialist financial advisors or mortgage brokers. While some brokers are paid a commission directly by the lender, others charge a separate fee for their advice and arrangement services.

This fee is crucial because RIO mortgages require expert guidance. The Financial Conduct Authority (FCA) mandates that specific advice must be given before taking out such a long-term, specialised product.

Ongoing and Contingent Costs of a RIO Mortgage

Once the RIO mortgage is secured, the ongoing costs primarily revolve around interest payments, but you must also be aware of potential costs that arise if your circumstances change.

1. Interest Rates

The interest rate determines the size of your monthly payment. Although RIO mortgages are interest-only, the rate secured is typically comparable to standard residential mortgages. However, because the loan term is potentially very long, the cumulative amount of interest paid over the life of the loan can be substantial.

Lenders perform robust affordability assessments to ensure that the borrower can reliably meet the monthly interest payments for the anticipated duration of the loan. As part of preparing for this assessment, understanding your current financial status is key. Get your free credit search here.

2. Early Repayment Charges (ERCs)

If you decide to pay off the mortgage capital early—perhaps because you downsize sooner than expected, receive an inheritance, or remortgage to a different product—you may incur an Early Repayment Charge (ERC).

  • When they apply: ERCs are typically enforced during a specific introductory period (e.g., the first five or ten years of the loan) when the borrower is locked into a fixed or discounted rate.
  • Cost: ERCs are usually calculated as a percentage of the outstanding loan balance, often starting high (e.g., 5% in year one) and reducing over the locked-in period.

3. Administration and Statement Fees

While often small, some lenders charge nominal fees for administrative tasks, such as producing copy statements or changing payment details. These should be detailed in the Key Facts Illustration (KFI) provided during the application process.

Exit Fees and Final Repayment

RIO mortgages are designed to run until the property is eventually sold, usually following the death or move into long-term care of the last surviving borrower. At this point, two final fees may apply:

Exit Fee: Some lenders charge a small, fixed fee (e.g., £50–£150) upon the final redemption of the loan to cover administrative costs of closing the account and removing the charge on the property title. However, exit fees are increasingly being phased out or absorbed by lenders.

Final Legal Costs: The deceased’s estate or surviving family will incur legal costs associated with the sale of the property and settling the outstanding mortgage capital.

The Importance of Affordability Checks and Risk

While the fees mentioned above contribute to the overall cost, the most crucial element of a RIO mortgage is the certainty that the borrower can consistently meet the monthly interest payments, even if interest rates rise in the future.

Lenders must stress-test affordability, ensuring income—such as pensions, investments, or rental income—is sufficient. This level of scrutiny is essential because of the long-term nature of the product and the severe consequences of default.

It is vital to budget not only for the interest payment but also for the fees detailed above, as non-payment has serious implications. Your property may be at risk if repayments are not made. Consequences of failing to meet the required interest payments include legal action, increased interest rates, additional charges, and ultimately, repossession of the property by the lender.

People also asked

Are RIO mortgage interest payments tax-deductible?

No, for residential property used as your primary residence, the interest paid on a RIO mortgage is typically not tax-deductible. Tax rules primarily allow interest relief on buy-to-let properties or business loans, not personal residential mortgages.

What happens if I miss an interest payment on a RIO mortgage?

Missing an interest payment means you are in breach of the mortgage contract, which can lead to late payment charges, negative impacts on your credit file, and escalation of the issue toward potential default, which carries the risk of repossession.

Is there a difference between RIO fees and Equity Release fees?

Yes, while both are later life products, RIO mortgages typically have fees (arrangement, valuation) similar to standard residential mortgages because they require ongoing affordability checks. Equity Release schemes (like Lifetime Mortgages) often include higher specific legal costs due to the complex nature of the guarantee that interest will never be owed by the estate more than the property’s value.

Do I have to pay an exit fee if I die while the RIO mortgage is active?

If an exit fee is stipulated in the contract, it is usually paid by the deceased’s estate during the redemption process, when the property is sold to clear the outstanding capital loan amount.

Can RIO fees be added to the loan?

Many lenders allow the major upfront fees, particularly the arrangement or product fee, to be rolled into the loan balance. However, this increases the total amount borrowed, meaning you will pay interest on those fees for the entire duration of the mortgage.

Summarising the True Cost of a RIO Mortgage

The total cost of a Retirement Interest Only mortgage is a combination of fixed upfront costs and the cumulative interest paid over the potentially lengthy term of the loan. A responsible approach requires carefully comparing the initial fixed fees (product, valuation, legal) between different lenders and calculating the total potential interest repayment over your expected term.

Since the market for RIO mortgages is specialised, consulting with a qualified, independent financial advisor who understands later life lending products is essential. They can provide a full breakdown of all fees and help you secure a product that aligns with your retirement income and long-term financial goals.
