The Loan-To-Value Ratio (LVR) is the loan amount expressed as a percentage of the property value your lender uses for the deal, normally the lower of the purchase price and the lender’s own valuation. It is the single number that drives your client’s pricing tier, whether Lenders Mortgage Insurance applies and how the application gets assessed, so it shapes everything from interest rates to approval strategy.
This guide covers the calculation, what moves it, where it triggers costs and how to reduce it for a marginal borrower.

How LVR is calculated
LVR = (Loan Amount ÷ Property Value Used by the Lender) × 100
A $400,000 loan against a $500,000 valuation gives an LVR of 80%. Note the denominator: lenders typically use the lower of purchase price and their valuation, so a bargain purchase price does not create instant equity. A client buying at $480,000 with a bank valuation of $500,000 still gets assessed on $480,000.
What LVR changes
LVR is a risk measure. Below roughly 80%, borrowers generally access sharper pricing and more loan terms to choose from. Above that line, most lenders require Lenders Mortgage Insurance (LMI), which protects the lender rather than the borrower and can add thousands to the loan. Treat 80% as a common market trigger rather than a legal threshold: some lenders write LMI from higher starting points or waive it under specific schemes, while low-LVR applications can still attract LMI on certain niche products.
Reducing a marginal LVR
- Bigger deposit: every dollar saved cuts the numerator directly; crossing 80% removes most LMI costs.
- Check the valuation: order upfront valuations before lodging, because one conservative valuer can push an 82% application over the insurance line while another comes back at 79%.
- Guarantor support: family-guarantee arrangements let a parent’s property secure part of the loan; Westpac’s Family Security Guarantee is one current named version, with the guarantor carrying real liability and independent legal advice required, and availability varies by lender rather than being universal.
- Government schemes: Housing Australia’s 5% Deposit Scheme lets eligible buyers purchase with a 5% deposit (2% for some single parents and guardians) without paying LMI, because Housing Australia guarantees the top slice to a participating lender.
Where regulation actually sits
No Australian rule dictates how LVR must be calculated for a consumer loan; each lender sets its own policy inside prudential expectations. The APRA requirement brokers meet most often is the serviceability buffer, which tests borrowing capacity at the loan rate plus three percentage points and ignores discounted introductory rates, so a high-LVR applicant faces both insurance costs and tighter capacity maths.
Your next step
For your next application sitting between 78% and 85%, run two valuations and recompute the LVR on both results before choosing a lender. That ten-minute check regularly turns an LMI-liable submission into a sub-80% approval.
