Understanding LVR: Loan-to-Value Ratio Explained

LVR—loan-to-value ratio—is one of the most important numbers in mortgage lending. Understanding it can save you thousands of dollars.

LVR is simply the percentage of a property’s value that you’re borrowing. If you’re buying a AUD 500,000 home and borrowing AUD 400,000, your LVR is 80% (the loan is 80% of the property value).

Why does this matter? Because LVR directly affects two things: your interest rate and whether you’ll pay mortgage insurance.

Mortgage insurance is required when you’re borrowing more than 80% of the property value. If you’re buying that AUD 500,000 home with a AUD 400,000 loan (80% LVR), you don’t need insurance. But if you’re buying with a AUD 450,000 loan (90% LVR), you’ll need lenders’ mortgage insurance (LMI).

LMI can be expensive. For a AUD 450,000 loan on a AUD 500,000 property, LMI might cost AUD 15,000 to AUD 25,000, depending on the lender and your circumstances. This gets added to your loan balance, so you’re paying interest on it over the life of the loan.

From a rate perspective, lenders charge a small premium for higher LVR loans. At 95% LVR, your interest rate might be 0.25% to 0.5% higher than at 80% LVR. This reflects the higher risk the lender takes on.

As a first-home buyer, you might be eligible for grants or concessions that help with your deposit, which improves your LVR. The FHOG can add tens of thousands to your deposit, bringing your LVR down and sometimes eliminating the need for mortgage insurance entirely.

Here’s a practical example: you’re buying a AUD 600,000 home with AUD 30,000 in savings. Without any grants, that’s a 95% LVR and you’d pay for mortgage insurance. But if you receive a AUD 20,000 FHOG grant, your total down payment is AUD 50,000, bringing your LVR to about 92%, and you’d still pay insurance. However, some lenders have agreements with state schemes that treat the FHOG as additional equity, effectively lowering your LVR.

The strategy is clear: save a bigger deposit to improve your LVR. Getting to 80% LVR saves you the mortgage insurance cost entirely. If you can’t reach 80% upfront, look for government schemes and grants that improve your position.

Some lenders also allow you to build equity over time—they might lend at 95% LVR with insurance initially, then offer to remove the insurance once you’ve paid down to 80%. This can be a cost-effective path forward if you’re confident about your repayment capacity.

Understanding LVR helps you make smarter borrowing decisions and see the long-term cost of different deposit scenarios.
