The short answer
The moment you take on a mortgage is the moment your insurance need changes most sharply in your life — because for the first time there is a large debt that does not disappear if your income does.
The starting shape for most first-home buyers: life cover sized to the mortgage, plus something protecting your income — full income protection if you can afford it, mortgage repayment cover if you cannot.

What changed the day you signed
Before the mortgage, if you could not work, you could move somewhere cheaper. After it, you have a fixed monthly obligation secured against the roof, and a bank that is not interested in why your income stopped.
That is the whole argument. It is not about death — it is about the fact that a mortgage converts a flexible cost into a rigid one.
The shape, in priority order
Something that protects your income
The most likely bad scenario is not dying — it is being unable to work for a long stretch. Income protection is the fuller answer; mortgage repayment cover is the affordable one. If budget is genuinely at the limit, start with mortgage cover and upgrade later — the comparison is here.
Life cover sized to the debt
If you bought with a partner, this is about whether the survivor keeps the house. Size it to the mortgage plus a buffer, not to a round number. Use the cover calculator.
Health cover, while you are young and well
Cheapest it will ever be, and your medical history is as clean as it will ever be. Every year you wait removes conditions from your future policy. A high-excess hospital plan is the value option — see the excess lever.
Trauma, when there is room
A modest amount, sized to twelve months of outgoings, does real work without a large premium.
A mortgage turns a flexible cost into a rigid one. That is what you are insuring.
About the cover the bank offers
It is convenient, and convenience at that moment is worth something. But it is worth knowing three things before you tick the box:
- It is often sized to the lender's exposure rather than your household's needs.
- The bank is sometimes the beneficiary, meaning the payout clears the debt rather than going to your family to decide what to do with.
- Some bank-arranged cover is underwritten at claim time rather than at application. That sounds convenient and is the opposite — it means you discover whether you were actually covered at the worst possible moment.
None of that makes it wrong. It makes it worth comparing before you accept it in a room where you have already been signing documents for two hours.
Doing it on a stretched budget
Almost everyone is stretched at this point, and the honest advice is that a cheaper policy you keep beats a better policy you cancel in eight months. Levers that reduce premium without gutting protection:
- Lengthen the income protection wait period to match your actual leave and savings.
- Keep the benefit period long — this is the part doing the real work.
- Raise the health insurance excess substantially.
- Skip the everyday/extras module.
- Start with mortgage repayment cover, and diarise a review in two years. The review is the part people skip, and it is the part that matters.
If you are buying with a partner
Cover both of you, not just the higher earner. The lower earner's contribution is frequently underestimated because it does not show up as salary — childcare, time, the ability to work at all. And check the ownership structure so a payout goes where you intend it to.
Common follow-up questions
Do I have to take the insurance the bank offers to get the loan?
No. Lending is not conditional on buying the lender's insurance. You are free to arrange cover wherever you like, including after settlement — though do not leave a long gap, because the exposure starts the day the loan does.
We are young and healthy. Can we wait a couple of years?
You can, and the risk of something happening in those two years is genuinely low. The cost of waiting is not really the risk — it is that premiums are set from your age at application and health cover excludes whatever medical history you accumulate in the meantime. Waiting is a bet that costs a little if you win and a lot if you lose.
Should the policy be owned personally or jointly?
It affects who receives the money and how quickly, and it interacts with your relationship property position and any trust. It is a short conversation with an adviser and worth having before the policy is issued rather than after.
