LMI Explained: When to Pay It vs Avoid It

—

Lenders Mortgage Insurance (LMI) protects the bank, not you. Yet you pay it. Understanding when it’s worth swallowing vs avoiding can save you tens of thousands.

What LMI Is

If you borrow more than 80% of property value (LVR > 80%), most lenders require LMI to protect themselves against default.

Cost: 1–4% of loan amount, depending on LVR and loan size
Paid: Once upfront (or capitalised into loan)
Refundable: No, ever
Tax-deductible: For investors, may be over 5 years; not for owner-occupiers

Approximate LMI Costs (2026)

For an $800,000 property, $720k loan (90% LVR):

LMI: ~$15,000–22,000

For a $600,000 property, $570k loan (95% LVR):

LMI: ~$22,000–28,000

The closer to 100% LVR, the steeper the percentage.

When Paying LMI Makes Sense

You’d lose more by waiting for a 20% deposit (rapidly rising market)
You can’t realistically save another 5–10% before prices increase further
Your career is on an upward trajectory with strong income growth coming
The property is significantly underpriced and unlikely to stay so

When LMI Is a Mistake

You could comfortably wait 6–12 months to save the remaining deposit
The property is in a flat market
You’re stretching every cent to qualify
You’re in a buyer’s market with falling prices

Ways to Avoid LMI Entirely

1. Government Schemes:

First Home Guarantee: Government guarantor up to 15% deposit gap. Limited spots.
Family Home Guarantee: For single parents, 2% deposit possible.
Regional First Home Buyer Guarantee: Regional areas, same idea.

2. Family Guarantee Loans: Your parent uses their home equity as additional security. You can borrow 100%+ without LMI. Risk: parents are on the hook if you default.

3. Professional LMI Waivers: Doctors, lawyers, accountants, engineers above income thresholds can borrow up to 95% with no LMI. Lender-specific.

4. First Home Super Saver Scheme: Use voluntary super contributions (tax-favorable) to grow your deposit faster. Limited but useful.

The 5-Year Hold Math

LMI of $15,000 on a property growing 5% annually for 5 years:

Property gain: ~$220,000 on $800k
LMI cost: $15,000 (~7% of gain)

If you’d waited 2 years to save the deposit, you’d miss ~$80,000 of growth. LMI was actually cheap.

But in flat/declining markets, the math flips entirely.

⚠️ Reality Check: LMI is structurally rigged for lenders. But sometimes “rigged” doesn’t mean “wrong choice for you.”
