Can I transfer my RIO mortgage to a new property?
26th March 2026
By Simon Carr
TL;DR: While most Retirement Interest Only (RIO) mortgages are ‘portable,’ meaning you can transfer your RIO mortgage to a new property, approval is not automatic. The new property must meet the lender’s criteria, and you will need to undergo a full affordability reassessment based on your current retirement income to ensure the move remains sustainable.
Moving home in later life can be complex, especially when you have a specialised product like a Retirement Interest Only (RIO) mortgage. A RIO mortgage allows you to pay off only the interest on the loan, with the capital being repaid only when a specified life event occurs, such as moving into long-term care, the last borrower passing away, or selling the property.
If you are planning to move, one of your primary concerns will be whether you can keep your existing mortgage product. This process is known as ‘porting’ the mortgage.
Understanding if You Can Transfer Your RIO Mortgage to a New Property
The straightforward answer is that yes, you can typically transfer your RIO mortgage to a new property, provided your existing lender allows porting and you meet all the necessary criteria for the new property purchase. Porting is generally favoured by borrowers because it allows them to maintain the same interest rate and avoid Early Repayment Charges (ERCs) associated with settling the old loan early.
However, the ability to transfer is never guaranteed. Because a mortgage is secured against a specific property, when you move, the lender effectively needs to assess the risk of the new property and reassess your financial stability.
The Crucial Role of Affordability and Eligibility Checks
Even though you already hold the RIO product, the lender treats the porting process almost like a brand-new application. This is essential for compliance, ensuring the loan remains affordable and suitable for your circumstances under the new arrangement.
1. Affordability Reassessment
Unlike standard interest-only mortgages, RIOs are designed for those in retirement, meaning affordability is based primarily on guaranteed retirement income (such as pensions, state benefits, and certain investment incomes). When you port, the lender will check:
- Whether your current income is sufficient to cover the interest payments now, and likely into the future.
- If there have been any significant changes to your income or outgoings since the original application.
2. New Property Valuation and Criteria
The new property must satisfy the lender’s valuation and security requirements. This often means:
- The property must be deemed suitable collateral by the surveyor.
- It must meet specific criteria related to its construction, location, and potential saleability.
- The Loan-to-Value (LTV) ratio must remain acceptable to the lender, especially if you are borrowing a different amount.
3. Credit Status Review
The lender will review your credit file to ensure you have maintained a good payment history, particularly on your existing RIO mortgage, and have no new defaults or significant adverse credit events. Maintaining a good credit score is crucial for any financial application.

The Process of Porting Your Retirement Interest Only Mortgage
The process of transferring your RIO typically involves several key steps. It is vital to start this process early, ideally as soon as you begin searching for a new property, as mortgage applications can take time.
Step 1: Contact Your Current Lender
The first action should always be to contact your existing RIO provider. Ask them directly: “Can I transfer my RIO mortgage to a new property?” They will confirm if the product is portable and explain their specific requirements for a new application. They will also confirm any potential Early Repayment Charges (ERCs) that might apply if you fail to complete the porting within their specified timeframe (usually 90 days or six months after selling your old home).
Step 2: Obtain a Mortgage in Principle for the New Property
Once you have found a new property, you will need to complete a new mortgage application with your current lender, specifying that it is a porting request. The lender will issue a Mortgage in Principle based on the new valuation and your affordability.
Step 3: Managing the Time Gap (Bridging)
One of the most complex elements of porting is managing the period between selling your old property and purchasing your new one. If you complete the purchase and sale simultaneously, the transfer is seamless. If there is a delay, you may temporarily require a bridging solution or need to pay off your original RIO mortgage (incurring ERCs) and apply for a new one later.
- Simultaneous Completion: The sale and purchase occur on the same day, simplifying the legal transfer of the debt security.
- Temporary Gap: If you sell first and rent temporarily, you must repay the RIO, incurring ERCs. You can then apply to the lender to refund the ERCs when the porting application on the new property is completed, provided the terms allow.
Step 4: Completion and Legal Transfer
Your solicitor or conveyancer plays a critical role in liaising with the lender to ensure the charge is correctly transferred from the old property to the new one. They must confirm that all legal requirements relating to the new property are met.
What If You Need to Borrow More (Further Advance)?
It is common when moving home for the new property to cost more, requiring a larger loan. If you need to borrow more than your existing RIO balance, this is known as a ‘further advance’.
The lender will assess the further advance separately. The existing RIO amount will typically be ported onto your existing rate, while the additional borrowing will be on a new RIO product at the lender’s current interest rate. This often results in a ‘split loan’, where you have two different RIO accounts with different rates and terms, secured against the same property.
- The further advance is subject to stringent affordability checks, ensuring you can cover the increased interest payments.
- You must meet the lender’s updated LTV requirements for the new, higher loan amount.
Key Risks and Considerations When Porting a RIO Mortgage
While porting can save you money on charges, it is not without risk, particularly regarding timing and eligibility.
- Risk of ERCs: If you sell your current property but cannot complete the purchase of the new property quickly enough, or if the new property is rejected by the lender, you may be forced to pay the outstanding Early Repayment Charges on your original RIO.
- Higher Payments: If you require a further advance, your monthly interest payments will increase, placing greater strain on your retirement income.
- Eligibility Failure: Changes in your financial circumstances or the new property failing valuation could lead to your porting request being denied, potentially leaving you without a suitable mortgage product.
As with all secured loans, it is vital to keep up with your interest repayments on your RIO mortgage. Failure to do so can have serious consequences. Your property may be at risk if repayments are not made. Consequences of default can include legal action, repossession, and potentially increased interest rates and additional charges being levied.

People also asked
How long does the RIO mortgage porting process usually take?
The timeline largely depends on the speed of the conveyancing and valuation process for the new property. If you already have a lender, it typically takes between six to twelve weeks from submitting the full application to completion, assuming no major legal complications arise.
What if the new property I buy is cheaper than the old one?
If the new property is cheaper, you will need a lower loan amount. You must pay down the difference in the capital when the sale completes. This partial repayment may incur an Early Repayment Charge on the repaid portion, depending on your original RIO product terms. Always check your ERC agreement.
Is porting a RIO mortgage always better than getting a new one?
Not always. While porting helps you avoid existing ERCs, you may find that current market rates for new RIO products are significantly lower than the rate you are currently paying, making a new application potentially cheaper in the long run, even after factoring in the ERC cost.
Can I transfer a RIO mortgage if the joint borrower moves into care?
In most RIO agreements, moving into long-term care by one of the borrowers is a specified life event that could trigger the requirement to repay the loan capital. However, lenders often allow the remaining borrower to port the RIO to a new property, provided they can individually demonstrate affordability for the interest payments.
What is the maximum age limit for a RIO mortgage when porting?
Most RIO mortgages do not have an upper age limit, as the capital is repaid upon a life event rather than a fixed date. However, affordability is still critical; the lender must be satisfied that your income can sustain the interest payments for the anticipated duration of the loan.
Conclusion: Planning Your RIO Mortgage Transfer
The key to successfully transferring your RIO mortgage to a new property is meticulous planning and early communication with your existing lender. While the process of porting is designed to be helpful, remember that your eligibility is reassessed, and the new property must meet all standards.
Ensure you understand the terms regarding Early Repayment Charges, particularly if there is a gap between selling and buying. If you are uncertain about the financial implications or wish to explore alternative later-life borrowing products, seeking independent financial advice from a specialist mortgage broker is highly recommended.

THINK CAREFULLY BEFORE SECURING OTHER DEBTS AGAINST YOUR HOME
REPAYING YOUR DEBTS OVER A LONGER PERIOD CAN REDUCE YOUR PAYMENTS BUT COULD INCREASE THE TOTAL INTEREST YOU PAY. YOUR HOME MAY BE REPOSSESSED IF YOU DO NOT KEEP UP REPAYMENTS ON A MORTGAGE OR ANY OTHER DEBT SECURED ON IT.
