What LMI actually costs at 85%, 90% and 95% LVR — and the five legitimate ways to avoid paying it at all.
Lenders Mortgage Insurance is the single most misunderstood cost in Australian home lending. Here's what it is, what it really costs, and how to legitimately avoid it.
What LMI Is (and Isn't)
LMI is a one-off insurance premium that protects the lender — not you — if you default and the sale of the property doesn't cover the loan. It applies when you borrow more than 80% of the property's value. It is not optional where required, but it can usually be capitalised (added to your loan) rather than paid in cash.
What Does LMI Cost?
LMI scales with both your LVR and loan size. Realistic ranges on an $800,000 purchase:
| Deposit | LVR | Typical LMI |
|---|---|---|
| 15% ($120k) | 85% | ~$6,000–$10,000 |
| 10% ($80k) | 90% | ~$12,000–$18,000 |
| 5% ($40k) | 95% | ~$25,000–$35,000 |
Premiums vary meaningfully between lenders because they use different insurers and rate cards — the same borrower can be quoted thousands apart. This alone justifies comparing lenders.
Five Ways to Avoid LMI
1. First Home Guarantee — eligible first home buyers purchase with 5% and no LMI; the government guarantees the difference. No place caps or income caps since October 2025.
2. Guarantor loan — a family member's equity secures the top slice of the loan, taking your effective LVR to 80% or below.
3. Professional LMI waivers — several lenders waive LMI to 90% (sometimes 95%) LVR for doctors, dentists, lawyers, accountants and select other professions.
4. An 80% restructure — sometimes a slightly cheaper property, a small gift, or the First Home Super Saver Scheme gets you under the 80% line, saving more than it costs.
5. Lender selection — where LMI is unavoidable, choosing the lender with the cheapest premium for your bracket can save $5,000+ on identical loans.
Is Paying LMI Ever Worth It?
Frequently, yes. If prices in your target area rise 5% while you save the extra deposit, waiting cost more than the LMI. We model both paths — buy now with LMI vs. save and wait — so the decision is made with numbers, not guesswork.
How LMI Premiums Are Actually Calculated
Premiums are set from a rate card crossing your LVR band against your loan size band, then multiplied through state stamp duty on insurance. Two insurers dominate the Australian market, but lenders negotiate their own rates and several self-insure through captive arrangements — which is why the same borrower can be quoted $14,000 by one lender and $19,000 by another for an identical loan. When LMI is unavoidable, we quote it across multiple lenders as part of any free assessment, because a $5,000 premium spread is common.
LMI vs Waiting: A Worked Example
Suppose you have 10% saved for an $800,000 home and LMI would cost $15,000. Saving the remaining 10% ($80,000) at $2,000/month takes 40 months. If your target market grows even 4% annually, that home costs roughly $910,000 by then — $110,000 more, requiring a bigger deposit again. Against that, $15,000 of LMI (capitalised) plus slightly higher-LVR interest is frequently the cheaper path. This is the buy-now-vs-wait model we run with real suburb data — see how it plays out in growth corridors in our renting vs buying analysis.
The Schemes That Beat LMI Entirely
Before accepting any premium, eliminate the free alternatives: the First Home Guarantee (5% deposit, no LMI, administered by Housing Australia) for eligible first-home buyers; guarantor structures for buyers with willing family; and professional waivers for doctors, dentists, lawyers, accountants and select others — several lenders waive LMI to 90–95% LVR for eligible professions with no scheme involvement at all. Our low deposit and guarantor service models all of these against the pay-LMI path so the decision is numbers, not guesswork. And whatever path you take, remember LMI protects the lender, not you — Moneysmart explains the distinction from mortgage protection insurance, which is a different product entirely.
Capitalising LMI: The Fine Print
Most lenders let you add the premium to the loan rather than paying cash — but the mechanics matter. The capitalised premium accrues interest for the life of the loan: a $15,000 premium capitalised over 30 years at ~6% costs roughly $32,000 in total. Some lenders also cap the maximum LVR including capitalised LMI (e.g. 97%), which can force part of the premium to cash at very high LVRs. Monthly-instalment LMI products exist with a couple of lenders — no upfront premium, a small monthly fee instead, and it stops when your LVR improves — occasionally the smartest structure for borrowers planning aggressive early repayments. And one myth to retire: LMI is not transferable and not refundable in any meaningful amount after the first year or two, so "I'll just move it when I refinance" isn't a plan. These second-order details are exactly what we compare, lender by lender, in a free assessment.
Frequently Asked Questions
Is LMI refundable if I refinance early?
Generally no — and LMI does not transfer between lenders. If you refinance above 80% LVR with a new lender you may pay LMI again, which is why timing refinances around your equity position matters.
Can LMI be added to my loan?
Yes, most lenders let you capitalise the premium onto the loan so you don't need it in cash — you'll pay a small amount of interest on it over time.
Which professions get LMI waived?
Policies vary by lender, but commonly: medical practitioners, dentists, optometrists, veterinarians, lawyers, accountants and some finance professionals — often up to 90–95% LVR with no LMI. We check every applicable waiver for you.
