The three routes side by side
| Question | Lifetime mortgage | RIO mortgage | Standard remortgage |
|---|---|---|---|
| Monthly payment | Often optional; some products require payments | Interest must be paid | Usually capital and interest; interest-only may be available |
| Income assessment | Varies; payment-required products need affordability checks | Retirement-income affordability required | Income affordability and term assessed |
| Interest roll-up | Possible if interest is not paid | Not intended while required payments are maintained | Not intended under normal repayment terms |
| When capital is repaid | Usually last borrower’s death or permanent care move | Usually last borrower’s death or permanent care move | At the agreed end of the term |
| Estate impact | Rolled-up interest can reduce equity | Capital stays broadly fixed if interest is paid | Repayment borrowing reduces as scheduled payments are made |
What affordability means in retirement
For a RIO or standard mortgage, a lender considers sustainable income and expenditure, existing debts and how payments could change. State and private pensions, rental income and other sources may be assessed differently by different lenders. Being over 65 is not an automatic refusal.
For joint borrowing, consider what income remains when either partner dies. A household budget that works with two pensions may not work for the survivor. Discuss the position openly before agreeing to a payment commitment. A payment-required lifetime mortgage also needs the relevant affordability assessment.
What happens to your home and inheritance?
With a lifetime mortgage, unpaid interest increases the debt and can use up a growing share of the property’s value. Property growth is uncertain and should never be relied on to cancel out compounding. Voluntary payments can slow growth, subject to the plan’s terms.
With RIO, paying interest maintains a broadly unchanged capital balance; your estate still has to repay that capital. With a standard repayment mortgage, scheduled payments reduce the capital, but the monthly payment may be higher. None of these options guarantees a particular inheritance or future house price.
Choosing a route around your budget
- Start with the amount actually needed, including any mortgage to clear, fees and a sensible reserve for later life.
- Set a realistic monthly budget that still allows for bills, maintenance and unexpected costs. Assess the surviving partner’s position where relevant.
- Compare personalised illustrations over the same periods, including rate changes, fees and repayment charges.
- Consider savings, downsizing or borrowing less before choosing a secured loan. If reliable monthly payments are not affordable, do not stretch your budget to fit a product.
Questions to bring to Adrian
- Will payments remain affordable after a pension or household-income change?
- Can I move home, repay early or make extra payments, and what would it cost?
- What happens to everyone living in the home when the last borrower dies or needs care?
- How do benefits and care funding change if I release cash?
- What would the outstanding balance be after 10 and 20 years under each illustration?
Common questions
Is a RIO mortgage the same as equity release?
No. RIO requires monthly interest payments and an affordability assessment. A roll-up lifetime mortgage can add interest to the balance instead. Both are secured on your home but have different payment rules.
Is the mortgage with the lowest rate always cheapest?
Not necessarily. Fees, term length, early repayment charges and whether interest compounds all affect the overall cost. Compare personalised illustrations, not the headline rate alone.
