I get asked about Lenders Mortgage Insurance almost every week, usually by a client who has just seen a number on their loan quote and wants to know why it’s there. It’s often the single biggest surprise cost in the whole home buying process, and it’s also one of the most misunderstood. So let’s go through it properly, from what it actually is, to what it costs, to every legitimate way you can avoid paying it.
Lenders Mortgage Insurance, or LMI, is a one off insurance premium that protects the lender if you default on your home loan and the property doesn’t sell for enough to cover what you owe. According to the Insurance Council of Australia, LMI exists to cover the lender, not you, and only the lender can make a claim on the policy.
Here’s the part that catches people off guard every time I explain it. If you default and the insurer pays out your lender, the insurer can still come after you personally for that amount. This is called subrogation. So LMI doesn’t clear your debt if things go wrong, it simply changes who you owe the remaining balance to. You pay the premium, the bank gets the protection, and you can still be chased for a shortfall. It’s a strange arrangement when you say it out loud, but understanding it properly means you go into your loan with your eyes open.
Banks and lenders see a smaller deposit as a bigger risk, because there’s less of a buffer between what you owe and what the property is actually worth. If you’re borrowing more than 80 percent of the property’s value, meaning your deposit is under 20 percent, most lenders will require LMI before they’ll approve your loan. NAB explains this clearly on its own LMI fact page, noting that LMI is generally required when a borrower doesn’t have the standard 20 percent deposit.
Without LMI, most lenders simply wouldn’t approve a loan with a deposit that small in the first place. So while it feels like a cost with no upside for you, it’s also the exact mechanism that makes low deposit lending possible at all. If LMI didn’t exist, most first home buyers would need a full 20 percent deposit before any bank would even consider their application, and for a lot of people that would mean years of extra saving.
LMI isn’t issued by your bank directly. It’s underwritten by a small number of specialist mortgage insurers, and your lender selects which insurer to use, not you. You can’t shop around for a cheaper LMI provider the way you might compare car insurance quotes. Each lender has an existing commercial arrangement with one or more insurers, and the premium you’re quoted comes from that insurer’s rate schedule as applied to your specific loan.
This matters more than most borrowers realise, because two lenders can quote noticeably different LMI premiums for the exact same property, deposit, and loan amount, simply because they work with different insurers or have different pricing arrangements in place. It’s one of the reasons comparing lenders properly, rather than accepting the first quote you’re given, can genuinely save you thousands of dollars before you’ve even signed anything.
This is where I see the most confusion, because LMI isn’t a flat fee and it isn’t calculated as a simple percentage everyone pays. It’s calculated based on your loan amount and your loan to value ratio (LVR), which is the percentage of the property’s value you’re borrowing.
As a rough guide, LMI can cost anywhere from around 1 percent to over 5 percent of your loan amount, and NAB notes it can reach up to 6.5 percent in some cases, depending on your deposit size, loan size, and lender. To make that concrete, here’s a worked example I often walk clients through. On a $600,000 property with a 10 percent deposit, meaning a 90 percent LVR, LMI might land somewhere in the vicinity of $8,000 to $12,000. Push that same property down to a 5 percent deposit, or 95 percent LVR, and the premium can climb to somewhere between $15,000 and $20,000. The gap between those two deposit sizes is only 5 percent of the purchase price, but the LMI cost can nearly double.
That’s because LMI pricing isn’t linear. It moves in bands based on your LVR, and crossing from one band into the next, say from 90 percent LVR into the 85 percent band, can produce a disproportionately large drop in your premium. This is exactly why I always tell clients it’s worth checking whether saving a little bit longer, even just a few extra months, would cross one of those pricing thresholds before locking in an application.
Most lenders will let you add, or capitalize, your LMI premium onto your loan rather than paying it as a lump sum in cash at settlement. On the surface this looks like the easy option, because it means you don’t need to find that extra cash on top of your deposit and other settlement costs. But it comes with a cost that a lot of buyers don’t think through properly.
When you capitalize LMI, you’re not just paying that premium once. You’re paying interest on it for as long as it sits on your loan, which for most people is a very long time. A premium of, say, $16,000 to $17,000 capitalised into a 30 year loan at a typical variable rate can end up costing well over $20,000 in additional interest over the life of the loan, on top of the original premium itself. So a cost that looked like $17,000 on your settlement statement can genuinely turn into closer to $38,000 by the time the loan is paid off. It’s not a reason to avoid capitalising LMI altogether, since for a lot of buyers it’s still the right call to preserve cash at settlement, but it’s a number worth seeing clearly before you decide.
Yes, the same 80 percent LVR threshold applies whether you’re buying an owner occupied home or an investment property. What changes is the pricing. Insurers generally view investment lending as carrying slightly higher risk than owner occupied lending, on the basis that an investor is statistically more likely to walk away from a negatively geared property than from their own family home. In practice, this can mean a modest loading on top of the standard premium for an investment purchase at the same LVR. It’s not usually a dramatic difference, but it’s worth factoring in if you’re comparing the numbers on an owner occupied purchase against an investment purchase at a similar deposit size.
Sometimes. If you pay out your loan in full within the first 12 to 24 months of settlement, some LMI providers will refund a portion of the premium on a pro rata basis. Outside that window, most LMI policies are non refundable, so if you’re planning to refinance or sell early, it’s worth checking with your lender or the insurer directly to see whether a rebate applies before you go ahead.
This is the part everyone actually wants to know, so here are the legitimate, tested ways to avoid it.
This is the most straightforward path. Once your deposit reaches 20 percent of the property’s value, your LVR drops to 80 percent or below and LMI generally isn’t required at all. It’s also worth knowing that a 20 percent deposit often unlocks a sharper interest rate too, since lenders view you as lower risk across the board, not just on the LMI question.
If you’re an eligible first home buyer, the Australian Government’s Home Guarantee Scheme allows you to buy with as little as a 5 percent deposit, or 2 percent under the Family Home Guarantee for eligible single parents, without paying LMI at all, because Housing Australia guarantees the remaining portion of the risk to the lender.
If a parent or close family member is willing to use equity in their own property as additional security, this can bring your effective LVR below 80 percent without you needing a full cash deposit, which means no LMI. This isn’t a decision to take lightly, since it does place real risk on the guarantor, so it’s worth having a proper conversation, and ideally independent legal advice, before going down this path.
Some lenders offer LMI waivers to certain professionals, commonly including doctors, dentists, vets, lawyers, accountants, and pharmacists, sometimes even at LVRs as high as 90 to 95 percent. Eligibility and which professions qualify varies significantly from lender to lender, so this really is a case by case check.
Because LMI is priced in bands rather than as a smooth percentage, saving even a modest amount extra to cross from one LVR band into the next can reduce your premium by far more than the extra deposit amount itself. Sometimes waiting a few extra months genuinely pays for itself several times over.
Honestly, sometimes yes. If property prices in your area are rising faster than you can realistically save the gap to a full 20 percent deposit, paying LMI to get into the market sooner can work out cheaper in the long run than waiting on the sidelines. It really comes down to your own numbers, your timeline, and how your local market is moving, and there’s no single answer that applies to every buyer. This is exactly the kind of calculation I sit down and run properly with clients before they commit either way, because on paper it can look like a cost to avoid at all costs, when in the right circumstances it’s actually a reasonable trade off.
FAQs
No. LMI protects the lender only. If you default, the insurer may cover the lender's shortfall, but you can still be pursued for that amount afterwards.
It's a one off premium calculated at the time of your loan. If you capitalize it into your loan amount, you'll pay interest on it over time as part of your regular repayments, but you won't be charged the premium itself again later.
Yes. LMI applies whenever your LVR is above 80 percent, regardless of whether the property is owner occupied or an investment, though some lenders price it slightly differently for investment loans.
Not directly, since it's set by the insurer based on your loan details rather than by the lender itself. What you can influence is the premium amount, by adjusting your deposit size or exploring the waivers and schemes covered above.
No. Lenders work with different LMI insurers, and pricing can vary between them for a similar risk profile. This is one of the reasons comparing lenders properly, rather than just accepting the first quote, can make a genuine difference to your bottom line.
No, and this trips a lot of people up. Mortgage protection insurance is a separate, optional product that covers your repayments if you're unable to work due to illness, injury, or job loss. LMI protects the lender, not you, and isn't optional if your deposit is under 20 percent.
Yes. Your lender or broker will confirm the exact LMI premium as part of your formal loan approval, before you're locked into anything. The figures in this guide are indicative ranges to help with planning, but your actual quote will be specific to your loan amount, deposit, and lender.
