What is Lender’s Mortgage Insurance (LMI)
Lenders Mortgage Insurance is a cost most borrowers meet when they buy with less than a 20% deposit. If you are borrowing more than 80% of a property's value — a loan-to-value ratio (LVR) above 80% — most lenders will require LMI, and the premium is usually added to your loan rather than paid up front.
It helps to be clear about what the premium actually does. LMI protects the lender, not you. It is a once-payable, non-transferable premium that covers the lender against loss if the loan defaults and a mortgagee sale does not recover the full balance. If you default on a $500,000 loan and the lender recovers only $450,000 on sale, the $50,000 shortfall is claimed against the LMI provider — who may then pursue you for that amount. So the insurance you are paying for is theirs; it does not protect you against default in any way.
That makes LMI a double-edged tool rather than a simple expense. It is the gate that lets a buyer into the market without a full 20% deposit, which is genuinely useful when the alternative is waiting years to save. But it is a real cost that compounds: because it is capitalised into the loan and interest is calculated daily, you pay interest on the premium for the life of the loan unless you clear it. The question worth getting right is not "is LMI good or bad" — it is whether, for your deposit and your timeline, the cost of entering now is worth more than the cost of waiting, and which lender's policy makes that trade cheapest.
How LMI Is Calculated and Loaded
There is no single LMI rate. Premiums are set by the insurers, and they vary by LVR, loan size and the type of purchase. As a general guide, a small premium applies at the lower end — an LVR just above 80% on a modest loan can sit well under 1% — and the rate climbs steeply as the LVR approaches 95%, where premiums can run several times higher. Loan term, GST, applicable state taxes and whether the purchase is a first home, a package or otherwise all feed into the figure. These bands are indicative only; the actual premium depends on the insurer and the specifics of your loan.
Stamp duty is also payable on the premium in most states, calculated as a percentage of the LMI cost — broadly in the order of 6% to 11% depending on the jurisdiction, with some states having removed it. Your lender's quote will reflect the duty that applies where you are buying.
Since around 2012, many lenders have applied loadings to the base premium for higher-risk profiles — for example where there are no genuine savings, where the security is an investment property, where the loan is a refinance, or where the borrower is self-employed. The detail that catches people is that loadings compound: each condition you meet stacks on the last. A self-employed investor refinancing without genuine savings can meet several at once, and the premium reflects all of them. Not every lender applies every loading, which is precisely why the lender you choose changes what LMI actually costs you.
It is also worth knowing that non-bank lenders often quote higher LMI than the major banks, frequently because they carry their own self-insured risk fee rather than a third-party premium. Same 85% LVR, different cost — it depends on the lender's policy.
Capitalisation, Exemptions and Avoiding LMI
Most lenders let you add the LMI premium to the loan rather than pay it separately; this is called capitalisation. The premium is added to your loan amount and the capitalised LVR is recalculated on the larger balance. Lenders cap how far they will let capitalisation push the LVR — commonly to 97%, though some insurers will stretch to 98%. If capitalising the premium would breach that ceiling, you may need to pay part of the LMI in cash to bring the loan back under the cap.
There are a few ways to avoid or reduce LMI entirely:
- A 20% deposit in genuine savings. This is the cleanest route, though note that "genuine savings" is defined differently by different lenders, so what qualifies is itself a policy question.
- A guarantor. A family member can offer their own property as additional security, which can allow you to borrow up to 100% of the purchase price plus costs without LMI. This is a significant commitment for the guarantor and should be understood fully on both sides before it is used.
- Occupational exemptions. Some professions — certain medical practitioners among them — qualify for LMI waivers or reduced premiums under specific lender policies.
And LMI is not necessarily permanent in its effect. If you take a loan with LMI, or accept a rate shaped by a high-LVR position, that need not be where you stay. Once you have demonstrated conduct on the loan, or once the property has gained enough value to bring your LVR back under 80%, refinancing into a stronger product becomes possible. The structural point is to treat a high-LVR entry as a starting position designed to be improved, not a fixed state.
Where LMI is required, the work is to source the least expensive option for your circumstances and structure the loan so the premium is not carrying you any longer than it has to.
