Bank valuation vs market value
A bank valuation is the lender's independent, conservative estimate of what a property would sell for, ordered to protect the lender; market value is what a buyer will pay in an open market, and the purchase price is what you agreed. The lender uses its valuation, not your price, to set the loan-to-value ratio, so a low valuation raises your LVR, can add lenders mortgage insurance, and can leave a cash shortfall. This guide covers why they differ, what happens when the valuation is low, and the three ways out.
- A bank valuation is ordered by the lender to manage its risk and is conservative by design; market value is what the open market pays (Duo Tax)
- The lender calculates your LVR on its valuation, which decides how much you can borrow and whether LMI applies (AMP)
- If the valuation is below the price: at or under 80% LVR the loan proceeds without LMI; above 80% LMI applies and can be added to the loan; many lenders will not go above 95% (ANZ)
- Three ways out: a bigger deposit to cover the shortfall, renegotiate the price, or a second valuation; Finder’s example is an $80,000 gap
- Off-the-plan is the high-risk case: the lender values the finished property a year or more after you paid the deposit (ANZ)
WARNING: This comparison rate is true only for the example given and may not include all fees and charges. Different terms, fees, or other loan amounts might result in a different comparison rate. Comparison rates are based on a secured loan of $30,000 over 5 years for vehicle finance and $50,000 over 5 years for equipment finance, as required under the National Credit Code.
What is a bank valuation, and how is it different?
Duo Tax publishes the cleanest distinction. A bank valuation is an independent assessment of a property's value ordered by a lender or mortgage broker, whose purpose is to protect the bank, not the buyer or seller; it estimates what the property would sell for in a conservative scenario so the lender can manage risk. A market valuation reflects what a buyer is willing to pay in an open and competitive market under normal conditions. The purchase price is a third number: what you and the vendor agreed. On most purchases the three are close, because a recent arm's-length sale is the best evidence of value. The valuer, instructed by the lender, works from recent comparable sales, location data, the property's condition and market trends, and the report belongs to the lender.
Why does it matter?
AMP publishes the consequence in one line: the bank valuation is used to calculate the loan-to-value ratio, which can affect how much you can borrow and whether you will be required to pay lenders mortgage insurance. Your deposit is fixed in dollars; the LVR is the loan divided by the valuation. If the valuation drops, the LVR rises even though nothing about your deposit changed.
| Purchase | Valuation | Loan needed | LVR on the valuation | Result (per ANZ's scenarios) |
|---|---|---|---|---|
| $800,000 with a $160,000 deposit | $800,000 | $640,000 | 80% | Loan proceeds, no LMI |
| $800,000 with a $160,000 deposit | $760,000 | $640,000 | 84% | Loan may proceed with LMI; LMI can be capitalised if you can service it |
| $800,000 with a $80,000 deposit | $740,000 | $720,000 | 97% | Above the 95% ceiling many lenders publish; shortfall must be covered |
The LMI calculator shows what the second row costs; the third row is the case where the deal falls over unless you find cash.
What happens if the valuation is lower than the price?
ANZ sets out the scenarios on its own page. If the lower valuation still leaves the LVR at or below 80%, the application goes ahead and you do not pay LMI. If it pushes the LVR above 80%, the loan may still go ahead but you pay LMI, and ANZ notes you could add the LMI to the loan if you have the income to service the larger amount. Many lenders will not lend at all if the LVR is more than 95%. Finder publishes what a buyer can do: cover the shortfall with a larger deposit, renegotiate the purchase price, request a second valuation, or look elsewhere for the funds; its example is a buyer named Don whose second valuation came back the same and who was left to borrow $80,000 from family or take a personal loan. The right order is: ask why. A broker can see the comparables the valuer used and, if they are wrong or stale, ask the lender for a second valuation from another firm on its panel, which is the cheapest fix. Renegotiating works when the vendor would rather cut the price than risk the sale. Topping up the deposit is the fallback, and a guarantor is the family version of it.
When valuations come in low
Four situations recur. Off-the-plan and new builds. ANZ publishes that the lender is only able to value the finished property, completion may be well over a year after you sign and pay the deposit, values may change over the construction period, and the lender will reassess the application before settlement; a shortfall then is the worst case because the contract is unconditional. Auctions. Competitive bidding can carry a price past the comparable sales, and there is no finance clause; the auction guide covers protecting yourself beforehand. Unusual properties. Rural blocks, mixed-use, very large or very small dwellings, and properties with few comparable sales get conservative treatment. Fast-moving markets. In either direction, the valuer's sales evidence lags the market by months.
What the lenders and guides publish
Checked against each source's published page on 20 September 2026.
| Source | What it publishes |
|---|---|
| ANZ | Why the valuation and purchase price can differ; the 80% and 95% LVR scenarios; LMI can be added to the loan if serviceable; off-the-plan reassessment before settlement |
| AMP | Bank valuations differ from market valuations and sale prices; the valuation sets the LVR and whether LMI is required; a higher LVR leaves you more exposed to rate rises |
| Finder | A market valuation guides the sale price, a bank valuation the lender's risk; if it is too low the lender might reject the application; options are a larger deposit, renegotiation, a second valuation or other funds |
| Duo Tax | Bank valuation is conservative and protects the bank; market valuation is open-market value; the difference affects approval, borrowing capacity and equity; the valuer uses comparable sales, condition and trends |
| Westpac (top-up page) | Covers the first valuation if one is needed for a loan increase |
Valuations on refinances and top-ups
The same report drives a refinance: the valuation sets the LVR tier, and so the rate and whether LMI applies on the new loan, and it decides your usable equity on a top-up; the home equity loan guide works through the 80% rule and the home equity calculator gives your figure from an estimate until the valuer has been through. Westpac publishes that it covers the first valuation on a top-up, and Bankwest one standard valuation. A broker will tell you the likely valuation range from comparable sales before anything is lodged, which is worth more than any calculator. Your Finance Guide refers you to one licensed broker partner for that; we do not lend or value property ourselves.
