Retirement Interest Only Mortgage Advice | Explore your Rio Mortgage Options

Mortgage advice before choosing a Retirement Interest Only mortgage

A Retirement Interest Only mortgage can look attractive because the monthly payment is usually based on the interest, not repayment of the capital.

But the lower monthly payment is only one part of the decision.

You may need to think about:

• Whether you can afford the monthly interest payments in the long term
• How and when the mortgage will be repaid
• Whether the mortgage affects your long term family plans
• Whether your income in retirement fits lender criteria
• Whether a standard mortgage, RIO mortgage or another option may be more suitable
• Whether you want to release money, refinance an existing mortgage, move home or stay where you are
• Whether tax, benefits or inheritance planning may be affected
• What happens if your circumstances change in future

This is why advice matters.

A mortgage broker salisbury like Your Mortgage Expert can help you understand whether a RIO mortgage is realistic and whether it fits your wider plans.

Retirement Interest Only mortgage advice at a glance

A Retirement Interest Only mortgage, often called a RIO mortgage, is a type of mortgage aimed at older borrowers. You usually pay the interest each month, with the capital normally repaid later.

A RIO mortgage may be considered if you want to refinance an existing interest only mortgage, borrow into retirement, stay in your home, move home in retirement or release money from your property.

Before choosing this route, it is important to check long term affordability, retirement income, repayment plans, lender criteria, the impact on your estate and whether another mortgage option may be more suitable.

What is a Retirement Interest Only mortgage?

A Retirement Interest Only mortgage is a type of mortgage aimed at older borrowers.

You normally only make monthly payments to cover the interest. The capital balance is usually repaid later, often when the property is sold, you die, move into long term care, or the mortgage term ends.

This is different from a repayment mortgage, where your monthly payments are designed to repay both interest and capital over the term of the mortgage.

With a RIO mortgage, the mortgage balance may stay broadly the same if you only pay the interest each month.

That can help with monthly affordability, but it also means the capital still needs to be repaid later. So you need to plan how you will pay the mortgage at the end of the term.

Why might someone consider a Retirement Interest Only mortgage?

You might consider a Retirement Interest Only mortgage for several reasons. These might include:

• Your existing interest only mortgage is coming to an end
• You want to stay in your home rather than downsize
• You want lower monthly payments than a repayment mortgage
• You need to refinance borrowing in retirement
• You want to release money from your home
• You want to move home later in your retirement
• Your current lender will not extend your mortgage term
• You have retirement income that can support the monthly interest payments

A RIO mortgage is not suitable for everyone, but it can be useful in the right circumstances.

The important question is whether it fits your income, property, repayment plans and long term needs.

What will lenders look at?

Lenders will usually assess whether you can afford the monthly interest payments.

They may look at:

• Pension income
• Employment income if you’re still working
• Investment income
• Rental income
• Other regular retirement income
• Your age
• The property value
• The mortgage amount
• Your credit history
• Your household spending
• Any other borrowing
• Whether the mortgage is single or joint
• What happens if one borrower dies or moves into care

Different lenders may assess the same case in various ways.

This is one of the reasons mortgage broker advice can be so useful, especially if your income is made up of several retirement sources.

Speak to a mortgage adviser

What income can be used for a RIO mortgage?

Whether your income will be accepted will depend on the lender.

Some lenders may consider various sources of your income such as:

• State pension
• Private pensions
• Workplace pensions
• Final salary or defined benefit pensions
• Drawdown income
• Investment income
• Rental income
• Employment income
• Self employed income

The key issue is whether the lender believes the monthly interest payment is affordable and sustainable.

If the mortgage is in joint names, some lenders may also consider whether the payment would remain affordable if one borrower died or moved into long term care.

The team at Your Mortgage Expert can help you understand how different lenders will assess your retirement income.

Can you use a RIO mortgage to repay an existing interest only mortgage?

Some clients consider a RIO mortgage because their existing interest only mortgage is coming to an end and they do not have the funds to repay the capital.

This can be a stressful situation, especially if you want to stay in your home.

A RIO mortgage may be one option to explore, but it is not the only route.

You may need to compare:

• Extending or changing your current mortgage
• Remortgaging to a new lender
• Retirement Interest Only
• Standard residential interest only
• Part and part borrowing
• Downsizing
• Using savings, investments or pension funds
• Support from family

We will help you understand the options before you decide what to do next.

Can you use a RIO mortgage to release money?

You may be considering a RIO mortgage because you want to release money from their home while continuing to make monthly interest payments.

This might be for home improvements, helping family, repaying existing borrowing, or improving financial flexibility in retirement.

This needs careful advice.

We can help you understand the mortgage options, but you may also need tax, benefits, legal or estate planning advice depending on your circumstances.

Can you get a RIO mortgage to move home?

You may be considering a Retirement Interest Only mortgage if you want to move home later in retirement.

This could include downsizing, moving closer to family, buying a more suitable home, or relocating in retirement.

Lenders will still need to assess your affordability, property value, equity and criteria. The mortgage will also need to fit your long term plans.

We can help you compare whether a RIO mortgage, standard mortgage, repayment mortgage, part and part option, or another route may be more suitable.

What are the risks of a Retirement Interest Only mortgage?

A RIO mortgage can be useful in certain circumstances, but there are important risks to understand.

These may include:

• The capital balance may not reduce
• You must keep up the monthly interest payments
• Your home may need to be sold to repay the loan later
• The amount left to your estate may reduce
• Your family may have fewer options when the mortgage becomes repayable
• Your income may change in later life

• The mortgage may affect benefits, tax or estate planning
• You may have fewer lender options than with a standard mortgage

A mortgage adviser like Your Mortgage Expert should help you understand these points before you proceed.
