How to Avoid LMI: 8 Proven Strategies for Australian Home Buyers

Lenders Mortgage Insurance can add $10,000 to $60,000+ to the cost of buying a home in Australia. It protects the lender — not you — if you default, and it applies whenever your loan exceeds 80% of the property value. The good news: there are several legitimate ways to avoid paying LMI entirely, and some don’t require saving a 20% deposit.

This guide covers every current strategy available to Australian home buyers, including options most guides barely mention.

What Is LMI and Why Does It Cost So Much?

Lenders Mortgage Insurance (LMI) is a one-off premium charged by lenders when your loan-to-value ratio (LVR) exceeds 80% — meaning your deposit is less than 20% of the property price. The insurance protects the lender against the risk of you defaulting on your mortgage. It does not protect you as the borrower.

LMI costs depend on three main factors:

Your LVR — the higher your LVR, the steeper the premium. A jump from 90% to 95% LVR can more than double the cost.
Your loan amount — premiums increase at key loan thresholds ($300K, $500K, $750K, $1M).
The LMI provider — lenders use different insurers (Helia, QBE, Arch) with different rate tables.

For a $750,000 property with a 10% deposit, LMI typically costs between $12,000 and $18,000. At 95% LVR on the same property, expect $28,000 to $38,000. You can estimate your LMI cost here.

Who Is Exempt from LMI?

There is no blanket LMI exemption in Australia — it depends on your circumstances. You won’t pay LMI if any of the following apply:

Your deposit is 20% or more (LVR at or below 80%)
You qualify for a professional LMI waiver through your occupation
You use the First Home Guarantee (government covers the LMI gap)
A guarantor secures your loan against their own property
Your lender has a higher LMI-free threshold (some waive LMI at 85% LVR)

Each of these pathways works differently. Here’s how to determine which one suits your situation.

1. Save a 20% Deposit

The most straightforward way to avoid LMI is to keep your LVR at 80% or below. On a $750,000 property, that means a $150,000 deposit. On a $1 million property, $200,000.

This eliminates LMI entirely, no conditions attached.

When this makes sense: You have time, a strong savings rate, and no urgency to enter the market. It also gives you access to the most competitive interest rates, since lenders reserve their best rates for borrowers at 80% LVR or below.

When it doesn’t: Property prices in your target area are rising faster than you can save. In Sydney and Melbourne, waiting another 2–3 years to save 20% could cost more in missed capital growth than the LMI itself.

2. Get an LMI Waiver Through Your Profession

Certain lenders waive LMI for borrowers in specific professions, allowing you to borrow up to 85%, 90%, or even 95% of a property’s value with no LMI charged. This is the single most effective exemption for eligible professionals — it saves thousands without requiring a larger deposit or government scheme.

Professions that typically qualify for LMI waivers include:

Medical professionals — doctors, dentists, optometrists, veterinarians, pharmacists
Legal professionals — lawyers, barristers, solicitors
Finance professionals — accountants (CPA/CA), actuaries, financial planners
Engineers — all disciplines with recognised qualifications
IT professionals — earning above income thresholds
Nurses and midwives — registered with AHPRA
Teachers — registered with a state teaching authority
Other professions — paramedics, police officers, public servants

The maximum LVR and income requirements vary by lender and profession. Most lenders require a minimum income of $150,000 (individual or household, depending on the lender), though some professions like doctors can qualify at lower incomes.

The key advantage over every other strategy: professional waivers have no place limits, no property price caps, and can be used on both owner-occupied and investment properties with some lenders.

Check if your profession qualifies — it takes 60 seconds and there’s no credit check.

3. Use the First Home Guarantee Scheme

The Australian Government’s First Home Guarantee (FHBG) allows eligible first home buyers to purchase with as little as a 5% deposit without paying LMI. The government guarantees the difference between your deposit and 20%, removing the lender’s need for mortgage insurance.

Since October 2025, the FHBG has been significantly expanded:

No place limits — previously capped at 35,000 places per year
Higher property price caps — Sydney’s cap increased from $900,000 to $1,500,000
Broader eligibility — anyone who hasn’t owned property in the past 10 years can apply, including permanent residents
Income caps removed for the guarantee component

The scheme also includes the Family Home Guarantee for single parents (2% deposit minimum) and the Regional First Home Buyer Guarantee for regional purchases.

When this makes sense: You’re a first home buyer, the property falls within the price caps, and you haven’t owned property in the past decade.

When it doesn’t: You’ve owned property before (unless 10+ years ago), you’re buying an investment property, or the property exceeds your area’s price cap.

4. Get a Family Guarantor

A guarantor loan allows a family member — typically a parent — to use the equity in their own property as additional security for your loan. This means the lender treats your borrowing as lower risk, and LMI is waived entirely.

With a guarantor, you can often borrow up to 100% of the property value (and sometimes up to 105% to cover stamp duty and costs) without paying a cent in LMI.

The catch: Your guarantor’s property is at risk if you default. They’re legally liable for the guaranteed portion of the loan, which is why lenders require independent legal advice for all guarantors.

Most borrowers aim to release the guarantor once they’ve built enough equity — typically when the loan reaches 80% LVR through repayments and property growth. This often takes 2–5 years.

When this makes sense: You have a family member willing and able to guarantee, you have stable income to service the loan, and you want to buy now without waiting to save a full deposit.

5. Choose a Lender That Waives LMI at Lower Thresholds

Not all lenders trigger LMI at the same LVR. While most charge LMI on any loan above 80% LVR, some lenders waive it up to 85% LVR for standard borrowers — no professional waiver or government scheme required.

If your deposit sits between 15% and 20%, this can save you thousands. On a $750,000 property, the difference between an 85% LVR loan without LMI and an 85% LVR loan with LMI can be $4,000 to $7,000.

This isn’t widely advertised. A mortgage broker who knows which lenders offer these thresholds can match you with the right option.

6. Structure Your Loan Below LMI Thresholds

LMI premiums jump at specific LVR bands: 80%, 85%, 90%, and 95%. They also jump at loan amount thresholds. Structuring your loan to sit just below a threshold — even by a few hundred dollars — can produce significant savings.

For example:

A $500,001 loan at 90% LVR costs notably more in LMI than a $499,999 loan at the same LVR
Dropping from 90.5% LVR to 89.9% LVR may move you into a lower premium band

Strategies to achieve this include increasing your deposit slightly (using savings, a gift, or a bonus), negotiating the purchase price down, or splitting the loan structure.

This isn’t about avoiding LMI altogether — it’s about reducing it by thousands if you’re close to a threshold. Use our LMI calculator to model different scenarios.

7. Use a Shared Equity Scheme

Shared equity arrangements allow a third party (government body or private company) to fund part of your purchase in exchange for a share of the property’s value. Because you’re borrowing less from the bank, your LVR drops below the LMI trigger point.

In Australia, the main shared equity options include:

State government schemes — such as Victoria’s HomesVic (currently paused) and WA’s Shared Equity Home Scheme
Private shared equity providers — such as OwnHome, which provides up to 20% of the purchase price

These schemes reduce your borrowing requirement, which can eliminate LMI entirely. However, they come with trade-offs: you’ll own less than 100% of the property, and the equity partner shares in any capital growth.

When this makes sense: You want to buy now, don’t qualify for a professional waiver or FHBG, don’t have a guarantor, and are comfortable sharing equity.

8. Combine Strategies

What most guides don’t mention: these strategies aren’t mutually exclusive. You can combine approaches for the best outcome.

For example:

Professional waiver + lower LVR — A nurse earning $120,000 could save an extra 5% deposit to bring their LVR from 95% to 90%, qualifying for more lenders with better rates — all while paying zero LMI.
FHBG + additional savings — Using the scheme with a 10% deposit instead of the minimum 5% gives you better rates and a lower loan balance.
Guarantor + professional waiver — If a guarantor can help you temporarily while you build equity, a professional waiver means you won’t need LMI even after the guarantor is released.

A mortgage broker who understands all these pathways can structure the most efficient combination for your circumstances.

Which Strategy Is Right for You?

Your Situation	Best Strategy	Potential LMI Saving
Doctor, lawyer, accountant, engineer, nurse, or other professional	Professional LMI waiver	$8,000–$40,000+
First home buyer, property under price cap	First Home Guarantee (FHBG)	$8,000–$30,000+
Parents have property equity, you have stable income	Guarantor loan	$8,000–$40,000+
Deposit is 15–19% of property value	Lender with 85% LMI-free threshold	$3,000–$8,000
Close to an LVR or loan amount threshold	Loan structuring	$2,000–$8,000
No professional waiver, no guarantor, not a first buyer	Shared equity or save to 20%	Varies

If you’re in an eligible profession, the professional LMI waiver is almost always the best option — it has no place limits, no property price caps, and works on subsequent purchases and investment properties.

How Much Does LMI Actually Cost?

To put the savings in perspective, here’s what LMI typically costs across common property prices (owner-occupied, principal & interest):

Property Price	5% Deposit (95% LVR)	10% Deposit (90% LVR)	15% Deposit (85% LVR)
$600,000	~$25,000	~$10,400	~$5,100
$800,000	~$35,000	~$15,200	~$6,800
$1,000,000	~$45,000	~$20,000	~$8,500

These are indicative ranges — actual premiums vary by lender and insurer. Investment property LMI is typically 15–25% higher. Use the LMI calculator for a personalised estimate.

Any strategy that eliminates these costs puts that money back in your pocket — or towards your deposit, furniture, or renovations.

Frequently Asked Questions

Can you avoid LMI with a 10% deposit?

Yes, in several ways. A professional LMI waiver allows eligible borrowers to buy at 90% LVR with no LMI. The First Home Guarantee also covers borrowers with deposits as low as 5%. A guarantor loan can eliminate LMI regardless of deposit size.

Is it better to pay LMI or wait until I have 20%?

It depends on your market and timeline. If property prices are growing 5–8% per year and you’re 2–3 years away from 20%, the price increase may exceed the LMI cost. If you qualify for an LMI waiver through your profession, you can avoid the trade-off entirely.

Is LMI refundable if I sell or refinance?

Some LMI providers offer partial refunds if the loan is repaid within the first 1–2 years. After that, refunds are unlikely. LMI does not transfer between lenders — if you refinance above 80% LVR, you may be charged LMI again by the new lender unless you have a professional waiver.

What professions are exempt from paying LMI?

Doctors, dentists, lawyers, accountants, engineers, nurses, teachers, IT professionals, police officers, and several other professions can qualify for LMI waivers. Requirements vary by lender — see the full list of eligible professions.

Can I avoid LMI on an investment property?

Professional LMI waivers apply to investment properties with some lenders. The First Home Guarantee does not cover investment purchases. Saving a 20% deposit or using a guarantor are the other main options for investors.
