Property Valuation vs Purchase Price: What Lenders Actually Use

When you buy a property in Australia, you might assume your lender will simply use the contract price as the property's value. They won't — they'll order their own valuation, and that figure may be different from what you paid.

Lenders use the lower of contract price or valuation when calculating your loan amount and LVR. This can have significant consequences if the valuation comes in below your purchase price.

Why Lenders Order Their Own Valuation

The lender is using the property as security for the loan. If you default, they need to be confident they can sell the property and recover the loan amount. Their valuation reflects what they believe the property would realistically sell for in a forced sale scenario.

This is typically more conservative than market price.

How Valuations Are Done

Lenders use one of several valuation methods:

• Full valuation — A licensed valuer physically inspects the property. Most accurate but takes 5–10 days.
• Desktop valuation — Based on similar sales in the area, no inspection. Fast but less accurate.
• Automated Valuation Model (AVM) — Computer-generated based on data. Quickest, only used for low-risk situations.
• Kerbside valuation — Valuer drives past, doesn't enter. Less common.

The type used depends on the property, LVR, and lender policy.

What Happens When Valuation Comes In Low

Say you agreed to pay $850,000 for a property. Lender valuation comes back at $810,000. The lender will base your LVR on $810,000 — not $850,000.

Difference: $32,000 you'd need to fund elsewhere — typically from extra cash or accepting a higher LVR (which means LMI).

Why Valuations Vary Between Lenders

Different lenders use different valuer panels. Each valuer has their own approach, comparable sales database, and risk appetite. Two valuers can value the same property differently — sometimes by 5–10% or more.

This is why a broker can be valuable: they know which lenders' valuations tend to come in stronger for which property types and locations.

What If You Disagree with the Valuation?

You can:

• Request a copy of the valuation report and challenge specific points
• Provide additional comparable sales that support a higher value
• Apply with another lender (different valuer)
• Pay for an independent valuation as evidence

Lenders can sometimes order a second valuation, but they aren't obligated to.

How to Reduce Valuation Risk

• Don't overpay at auction — A bid significantly above recent comparables is likely to fail valuation
• Get a pre-purchase valuation for unusual properties
• Choose lenders carefully for off-the-plan — Settlement valuations vary widely
• Check recent comparable sales — These are what valuers will use

Off-the-Plan: The Biggest Valuation Risk

The biggest valuation risk in Australian property is off-the-plan purchases — where the lender values at settlement, often 1–3 years after you signed the contract. If the market has dropped or comparable sales have weakened, the valuation may come in well below your contract price, leaving a funding gap to bridge.
