LVR and LMI explained: why the same deposit can cost different amounts

LVR (loan-to-value ratio) is how much you’re borrowing compared to the property’s value, shown as a percentage. LMI (Lenders Mortgage Insurance) is a one-off cost some lenders charge when your LVR is high, usually above 80%. LMI protects the lender if you can’t repay the loan and the property doesn’t cover the debt — it doesn’t protect you, and it isn’t optional once a lender’s threshold applies.

What changes the answer?

LVR is calculated on the lower of the purchase price or the lender’s own valuation, not just the price you agreed to pay — a soft valuation can push your LVR higher than you planned for. The LMI threshold, the premium itself, and whether waivers apply for certain professions all vary by lender, so the same LVR can mean a different actual cost depending on who you borrow from.

A worked example

A $700,000 purchase with a $595,000 loan sits at 85% LVR — above the common 80% threshold, so LMI is likely to apply. The same $595,000 loan against a $744,000 valuation would sit at exactly 80%, at or below the threshold for many lenders. A $10,000 difference in valuation, in either direction, can be the difference between paying LMI and not.

What varies by lender and product

• The exact LVR threshold where LMI starts (commonly, but not universally, 80%)
• Whether the premium can be capitalised into the loan or must be paid upfront
• Professional or income-based LMI waivers for some occupations
• How the Australian Government 5% Deposit Scheme changes the picture for an eligible Scheme loan (no LMI, subject to Scheme rules and a participating lender)
• How genuine savings, gifted deposits or existing equity are treated when calculating your effective deposit

What to prepare

Check your likely LVR before you get attached to a property, using a realistic valuation estimate rather than just the asking price. If you’re close to a threshold like 80%, a slightly larger deposit or a slightly lower purchase price can sometimes avoid LMI altogether — worth checking before you commit.
