Do All Banks Charge the Same LMI?

Most borrowers assume LMI is LMI — a fixed cost calculated the same way regardless of which bank you borrow from. It's not. The price you pay for Lenders Mortgage Insurance depends on which lender you choose, which insurer they use, and whether you qualify for a professional waiver. That variation can mean thousands of dollars difference between otherwise similar loan offers.

The short answer

No — LMI is not standardised across Australian lenders. The key variables are:

• Which LMI insurer the bank uses — CBA self-insures much of its high-LVR lending; Westpac and ANZ use Helia (formerly QBE LMI); NAB uses a mix; other lenders use various insurers including Genworth and others. Different insurers have different rate tables.
• The bank's risk appetite — some banks price aggressively and offer waivers that effectively eliminate LMI for professionals; others don't
• The loan size and deposit amount — LMI is calculated on the loan-to-value ratio and the loan amount, which compounds the difference at higher property values

Where the differences show up most

Professional borrowers save differently at each bank

This is the most significant variation. A doctor borrowing $700,000 with a 10% deposit at CBA pays zero LMI under the professional waiver program. At ANZ, that same doctor also qualifies for a waiver. But at a lender without a professional program, they pay $15,000–$22,000 for the same loan.

The difference isn't just the waiver — it's that some banks don't offer a professional waiver at all, while the big four each have their own version with different occupation lists and income thresholds.

The LMI premium itself varies

For borrowers who don't qualify for a waiver, LMI is charged by the lender's nominated insurer — and the rate tables differ. A $600,000 loan at 88% LVR might attract a different LMI premium at Westpac than at a smaller non-bank lender, even for the same borrower profile.

On a $600,000 loan at 88% LVR, LMI typically ranges from roughly $12,000 to $20,000 depending on the lender's insurer and rate table. On a $1 million loan, LMI can reach $30,000–$45,000.

The effective cost compounds in the loan

Here's what often gets missed: LMI is usually added to the loan, not paid upfront. That means you pay interest on it for the life of the loan. On a $20,000 LMI premium added to a $600,000 loan at 6.5% over 30 years, you're paying roughly $40,000 in extra interest on that LMI. The upfront difference between banks compounds over time.

A worked example: $750k property, 10% deposit

You're buying a $750,000 property. You have $75,000 (10%). You need to borrow $675,000. Here's how the LMI picture might differ:

Figures are indicative ranges based on publicly available LMI rate calculators as of April 2026. Actual figures will vary based on loan amount, LVR, borrower profile, and current insurer rate tables.

What this means in practice

If you're a qualified professional — especially a doctor, dentist, lawyer, or accountant — the difference between banks isn't just rate. The professional waiver at the right bank can eliminate your LMI entirely, which is a significantly better outcome than minimising it. In that sense, choosing your lender is partly an LMI strategy decision.

If you're not in a waiver-eligible profession, the differences are smaller but still meaningful. Comparing LMI across at least three lenders before settling on one can save you $2,000–$5,000 on the premium alone — and considerably more when you factor in the interest on a capitalised LMI.

A mortgage broker with access to a wide lender panel can usually identify which banks are most competitive for your specific situation in one conversation. That's faster than applying to four banks and pulling four different LMI quotes.

Quick summary

• LMI is not standardised — different banks charge different premiums and have different waiver policies
• Professional borrowers can eliminate LMI entirely at CBA, Westpac, NAB, or ANZ — but only if their profession is on each bank's eligible list
• Nurses should check Westpac specifically (it includes nurses; the other big four don't)
• Accountants and engineers: CBA, Westpac, and NAB have waivers; ANZ generally doesn't
• Non-professional borrowers: compare LMI across at least 3 lenders before deciding
• LMI added to the loan costs significantly more than face value due to interest

FAQ

Is LMI charged by the bank or an insurance company?

Lenders Mortgage Insurance is technically charged by a third-party insurer — but the lender passes the cost on to you. Most major banks use an LMI subsidiary: CBA self-insures directly, Westpac and ANZ primarily use Helia, NAB uses a mix of its own and third-party arrangements. Some smaller lenders use Genworth or other LMI providers. The cost and waiver policies still vary by lender, regardless of who the insurer is.

Can I get a different bank's LMI rate quoted to me?

You'd need to apply to each bank to get a formal LMI quote, which creates multiple enquiries on your credit file. A mortgage broker can assess your situation across multiple lenders without you needing to apply directly, and can identify which banks are most likely to offer the best LMI outcome for your profession and loan profile.

Does the LMI waiver apply to refinancing as well as buying?

Usually yes — but with conditions. Some banks extend professional LMI waivers to refinancing if you're borrowing above 80% LVR on the new loan. However, the criteria are often tighter for refinance cases than for purchases. Check with the specific lender before assuming.
