With each generation living longer than the last, pensions not stretching as far as they once did, and ambitions in retirement changing, later life mortgages are fast becoming the most popular way of managing finances later in life.
There is a wide range of different later life mortgage options available, with each type of product designed to offer flexibility and borrowing in situations where a traditional mortgage might not be suitable. This also means that later life mortgages work slightly differently from a traditional mortgage, starting with alternative eligibility criteria and extending to how they might be repaid over time.
With this in mind, understanding exactly how later life mortgages work is key to knowing if they could be a valuable tool for you. We’ve broken this down in this short guide, explaining the mechanics behind the different features of each type of later life mortgage.
What Are Later Life Mortgages?
Later life mortgages are products designed specifically for those aged 50 and over. While older borrowers can still be eligible for a more conventional type of mortgage, where the term ‘later life mortgage’ is concerned, we’re usually referring specifically to these products available only to those over 50.
There are three main types of later life mortgages, both of which involve a loan secured against the value of your home:
- Retirement Interest-Only (RIO) mortgages
- Lifetime mortgages
- Older borrower mortgages
These options give the borrower cash to spend on fulfilling a variety of personal goals, whether that’s paying off their existing mortgage, funding home improvements, gifting money to family, or helping with care costs. However, they have key differences in terms of their features, the way they are repaid and, where RIOs and lifetime mortgages are concerned, how they work in contrast to a standard mortgage.
Older borrower mortgages operate more like a traditional residential mortgage but are designed specifically for those borrowing into later life. Often, the maximum age at the end of the term can extend to even 90 years old. For these types of later life mortgages, lenders assess affordability on pension income, making them suitable for those who want a conventional mortgage structure but may be limited due to age when it comes to standard lenders.
How Repayments Work
Repayments are one of the key components of any kind of mortgage, ensuring that the borrower repays the amount owed plus any interest back to the lender over an agreed period of time. Although the way in which a later life mortgage is repaid differs from a conventional mortgage, repayments are still involved.
With a RIO, repayments cover the interest only. The amount borrowed remains outstanding for life and is settled from the eventual sale of the home. However, required monthly interest payments cover the cost of borrowing and keep the amount borrowed fixed. This repayment structure tends to mean that a RIO is most suitable for those with some form of steady income in retirement, as you’ll have to prove you can afford the required monthly repayments to be eligible.
Lifetime mortgages are different as they are a type of later life mortgage with no required repayments. Instead, interest is added to the amount borrowed each month and then repaid when the last surviving homeowner passes away or moves into care.
Older borrower mortgages, on the other hand, operate similarly to a standard repayment or interest-only mortgage. You can make either monthly capital and interest payments or just monthly interest-only payments with a plan to repay the loan amount at the end of the mortgage term. The key difference is that affordability to make these payments is assessed using pension income.
Interest Payments
Given that interest is added to the amount borrowed for both a RIO and a lifetime mortgage, interest is one of the biggest components of how later life mortgages work.
With a RIO, interest works in a rather conventional way in that you pay it monthly, and the loan balance remains the same throughout the lifetime of the loan.
However, with a lifetime mortgage, interest is added to the amount borrowed on a compound basis. What this means is that interest is added to the loan each month, with future interest then charged on the increasing balance. You do not have to repay any of this interest during your lifetime, but you do have the option to do so and make optional repayments to reduce the roll-up over time. Crucially, though, this type of later life mortgage is designed to function even if you choose to make no payments at all.
With older borrower mortgages, interest is charged in the same way as a standard mortgage, with payments covering at least the interest each month (and often the amount borrowed, too).
Moving Home
While later life mortgages commonly allow older homeowners to stay in their existing property but still release funds to achieve their retirement goals, there are circumstances in which you may wish to move again. In these cases, later life mortgages are designed to continue to work as RIOs, lifetime mortgages, and older borrower mortgage products are typically portable. This usually means that you can move home and take the mortgage with you, providing the new home meets lender requirements.
Inheritance & Home Value Impact
It’s a common misconception that later life mortgages work only by depreciating the entire value of your home and meaning that there will be nothing (or worse, debt) left to your loved ones. This is not strictly true. While borrowing against the value of your home will inevitably mean that there is less equity available when you pass away, a no negative equity guarantee is included with all lifetime mortgage products. This means that your loved ones will never owe more than the value of your home.
You can also make voluntary interest payments to reduce the amount that will be owed from the eventual sale of your home, and even choose to ring-fence a set portion of your home’s value for loved ones in the future.
RIO products are somewhat simpler when it comes to inheritance impact, as the amount that will need to be repaid when you pass away or move into care will be fixed from the start, offering greater certainty concerning what might be left behind.
Older borrower mortgages behave more like standard mortgages in this regard. Because they often involve repaying capital during the mortgage term, there may be more equity left in the property compared to the other later life mortgage options.
Benefits Entitlement
It’s also important to be aware that the way a later life mortgage works means that it can impact any entitlement to means-tested benefits. This is because both a RIO and a lifetime mortgage involve receiving a tax-free cash lump sum, which may mean that you are deemed to have savings or capital beyond eligibility thresholds. A qualified later life mortgage adviser can explain this to you in more detail.
