Mortgage protection with an interest-only loan
The balance doesn't go down. Coverage that does is the wrong product.
During an interest-only period you pay interest and none of the principal, so the balance stays where it started.
That single fact makes one common product actively unsuitable.
Decreasing coverage is the wrong shape
Decreasing term assumes an amortising loan. On an interest-only mortgage the balance isn't amortising at all, so the coverage falls while the debt doesn't move.
By the end of the interest-only period you'd hold materially less coverage than you owe — the opposite of the intended arrangement.
What happens when the period ends
The loan converts to a fully amortising payment over the remaining term, which is a shorter period for the same principal. Payments typically increase substantially at that point.
Some interest-only loans instead require a balloon repayment. Read the note and know which yours is, because a survivor facing a balloon needs the coverage to match the whole balance.
Why these loans are used
- Variable or bonus-weighted income, where lower required payments suit cash flow
- An investment property where rental income is being maximised
- An intention to sell or refinance before the period ends
- A plan to repay principal from a specific future event
Each of those has an insurance implication
If the plan depends on your future income, your bonus, a sale you'll arrange, or a refinance you'll qualify for, then the plan depends on you being there.
That's the real exposure. Level coverage for the full balance, running at least to the end of the interest-only period and preferably beyond, is what protects a household from inheriting a plan they can't execute.
Get the term right
- At minimum, cover through the end of the interest-only period
- Better, cover through the full loan term
- Include a conversion privilege in case the loan is extended or replaced
- Review it if you refinance, since that resets everything
- Check the note for a balloon repayment, and size for it
