Deposit Size and Loan-to-Value Ratio (LVR)
Definition
The Loan-to-Value Ratio (LVR) is the loan amount expressed as a percentage of the property's value:
LVR = Loan amount ÷ Property value × 100
Example: A $640,000 loan against a $800,000 property = 80% LVR. The borrower's equity contribution (deposit) is the remaining 20%.
The 80% threshold and why it matters
The 80% LVR threshold is the key policy boundary in Australian residential lending. Below 80%, the borrower avoids LMI and typically accesses standard residential rates. At or above 80%, LMI is triggered at most lenders — meaning the borrower pays a one-off premium to insure the lender against the additional risk.
How LVR is calculated
The LVR calculation always uses the lower of the contract price or the lender's independent valuation. If a borrower pays $850,000 for a property but the lender's valuer assesses it at $820,000, the LVR calculation is based on $820,000. The borrower must fund the $30,000 gap from their own resources — it cannot be added to the loan.
This means a borrower who budgets based on the purchase price can be caught short at settlement if the valuation comes in lower.
LVR tiers and their practical implications
- Below 80% LVR: Standard residential lending. No LMI required. Most lenders offer their best pricing at this tier. Full range of lender options available.
- 80–90% LVR: LMI required. The premium increases with LVR — 85% LVR LMI is materially cheaper than 90% LVR LMI. Fewer lenders, though most major lenders participate.
- 90–95% LVR: Higher LMI cost. More limited lender selection. Some lenders do not lend above 90% LVR at all. A small number of lenders offer LMI waivers for specific professions (medical, legal, accounting) at LVR levels up to 90% or occasionally higher.
LVR and interest rate pricing
Most lenders apply tiered interest rate pricing linked to LVR. A lower LVR loan represents less risk, and lenders typically reflect this in the product rate offered. The pricing advantage for sub-80% LVR borrowers varies by lender and product.
LVR versus the deposit amount needed
The deposit must cover both the LVR shortfall and the transaction costs — stamp duty, legal fees, building and pest inspection, and conveyancing. Many first home buyers focus on reaching a 20% deposit for the property price itself without accounting for transaction costs. The total funds required to complete a settlement are typically higher than the deposit alone.
Why Underwriters Focus Here
LVR is the primary measure of the lender's downside exposure. If property values fall and the borrower defaults, the lender's ability to recover the full outstanding debt depends on the sale proceeds relative to the loan balance. Higher LVR means less buffer between the loan balance and a realistic forced-sale price. The 80% threshold is the point at which most lenders require risk transfer to an LMI insurer.
Key Outcome Assessment Factors
The purchase price, the lender's independent valuation (which may be lower), the available deposit, whether any family guarantee equity is available, and whether the borrower qualifies for a professional LMI waiver. The LVR determines both the LMI requirement and the pricing tier applicable to the loan.
