Property valuation methods in Australia: bank valuation vs registered valuation vs agent appraisal

Three numbers describe the same house in Australian property: the bank valuation, the registered valuation, and the agent's appraisal. They often differ by 10 to 20 percent and occasionally by more. Each is produced for a different reader with a different incentive, and the gap between them is where most of the friction in a purchase ends up living. Knowing which figure to ask for, and which one to trust for which decision, is the part that saves money.

The three are not interchangeable. A bank valuation cannot be used to settle an estate. A registered valuation will not get a loan approved any faster. An agent appraisal is not a valuation at all in any regulated sense. The labels matter, and the labels are sometimes used loosely by the people quoting them. What follows is the working version of who does what.

Bank valuation: ordered by the lender, paid by the borrower

A bank valuation is commissioned by the lender as part of loan approval. The borrower usually pays for it, often through a valuation fee bundled into the application costs. The valuer is selected from a panel the bank manages, and the valuation report is delivered to the bank, not the borrower. A borrower can sometimes request a copy. They cannot usually choose the valuer.

Three things shape a bank valuation that other valuations do not share.

• Mortgage-in-possession brief. The valuer is asked to estimate what the property would realise in a forced sale within roughly 90 days. That assumption alone discounts the figure by 5 to 10 percent versus an open-market sale with a normal marketing campaign.
• Lender liability. Banks penalise panel valuers for over-valuing, because an over-valued property becomes a recovery problem if the loan defaults. Valuers who consistently print high get dropped from panels. The professional incentive runs one way.
• Desktop and drive-by variants. On refinances and lower-risk applications, the bank may accept a desktop valuation built from recent comparable sales without a physical inspection, or a drive-by where the valuer looks at the kerb only. Cheaper, faster, less accurate.

For a purchase, the bank valuation almost always lands at or below the contract price. The valuer's task is not to second-guess what the buyer agreed to pay; it is to confirm the security covers the loan. If it does, the contract price gets matched. If it does not, the val comes in short.

Registered (sworn) valuation: signed, dated, and binding

A registered valuation is produced by a Certified Practising Valuer who is a member of the Australian Property Institute (API) and works to the Australian Valuation Inspection (AVI) and International Valuation Standards (IVS). The report is signed, dated, and carries professional indemnity. The valuer can be sued if the figure is negligent. That liability is the main thing the signature is buying.

Registered valuations are required, not optional, in a defined set of situations.

• Family law settlements: when assets are being divided, the Family Court will not accept an agent appraisal.
• Deceased estates: probate and estate distribution among beneficiaries need a defensible value at the date of death.
• SMSF property: trustees must value fund-held property at market value each year for audit purposes; the ATO expects evidence.
• Related-party transfers: transferring a property between family members or related entities requires a market-value figure to avoid Division 7A and stamp-duty disputes.
• Partnership and trust dissolutions: buyouts between business partners or co-owners.

Cost for a residential property is typically $550 to $1,500 depending on complexity, turnaround, and whether a physical inspection is required. The report runs to 20 or 30 pages and lists comparable sales, condition, zoning, and the methodology used to arrive at the figure.

Real estate agent appraisal: a marketing document

An agent appraisal is the figure a real estate agent gives a vendor when pitching to win the listing. It is free, non-binding, and frequently optimistic. The agent is competing with two or three rival agencies for the engagement, and the appraisal is part of that pitch. The same agent will commonly rerun the figure once they have won the listing and are setting the marketing range with the vendor.

The appraisal is not produced under any professional standard. The agent does not carry liability for it. It is informed by recent local sales and the agent's read of buyer demand, both of which are real signal, but the figure itself sits one step removed from a valuation in the regulated sense. A buyer reading an agent appraisal should treat it as a marketing range, not a professional opinion on value.

Three approaches the valuer chooses between

Whoever is doing the valuing, there are three recognised approaches in Australian practice. A residential valuer will usually lean on one and reference the others as a cross-check.

• Sales comparison approach. The dominant method for houses, units, and townhouses. Take recent comparable sales in the same market, adjust for differences in size, condition, land area, aspect, street, and dwelling type, then triangulate. For ordinary residential property this is what the valuation actually is.
• Income approach. Capitalise the property's rental income at the prevailing market yield. Standard for commercial property and used for large-block investment residential where rental cash flow is the dominant value driver. Rarely the primary method for owner-occupier housing.
• Replacement cost (summation) approach. Land value plus the depreciated cost of building the improvements from scratch. Used for unique or special-purpose property where no useful comparable sales exist: prestige builds, large rural holdings, purpose-built facilities.

For a normal suburban purchase, the sales comparison approach is doing almost all the work. The valuer pulls three to six comparables sold within the last three to six months, adjusts each one, and lands inside the range they bracket.

Why bank valuations come in low

The structural answer is the brief. A bank valuation answers a different question than an agent appraisal. The bank wants to know what the property would realise in a forced sale on a 90-day clock, against an unmotivated buyer pool. The agent wants to know what a competitive marketing campaign with photography, a 28-day campaign, and bidding on auction day would produce.

Strip the marketing campaign out, compress the sale window, and add a conservative haircut for valuer panel risk, and the bank figure will sit 5 to 15 percent below the agent's appraisal in most markets, more in cooling ones. That is not the valuer being wrong. That is the valuer answering the question their brief actually asks.

The short val on refinance

Refinance valuations are where bank vals bite hardest. In a cooling market, the val often comes in below the original purchase price, because the comparables in the last few months have softened. The lender then sizes the new loan off the lower figure. The Loan-to-Value Ratio is recalculated against the new val, and if the LVR crosses the 80 percent threshold, Lenders Mortgage Insurance becomes payable on the refinance.

Sequence matters. The household refinancing to chase a lower rate can find the saving wiped out by an LMI premium triggered by a short val. Worth modelling the worst-case val before applying, especially if the original loan was taken near peak prices and the local market has since drifted. See LMI explained for the premium structure.

How to dispute a low bank val

Disputing a bank valuation is possible and sometimes successful, but not guaranteed. The process is informal and varies by lender.

• Request the valuation report from the lender, or at minimum the comparable sales the valuer relied on.
• Identify recent sales (within three months, same suburb, similar dwelling type, similar land size) that the valuer might have missed or undercounted.
• Submit those comparables in writing to the lender, with the addresses, sale prices, and sale dates.
• Ask the lender to re-instruct the valuer or, in some cases, instruct a second valuer from the panel.
• If the lender refuses, an independent registered valuation can be commissioned and submitted. The lender is not obliged to accept it but sometimes will.

Success rates are not published, but anecdotally a well-evidenced challenge with three or four strong comparables moves the figure roughly one time in three. The other two times the lender holds. Factor that probability into the decision about whether to spend $800 on an independent val.

A worked example

A buyer purchases a Brisbane house for $850,000 under contract. The listing agent appraised it at $880,000 to $920,000 in the pre-listing pitch. The buyer applies for a loan at 80 percent LVR, expecting to borrow $680,000.

The bank valuation lands at $820,000. The lender will size the loan off the lower of the contract price and the bank val, which is the bank val. At 80 percent LVR off $820,000, the maximum loan without LMI is $656,000. The buyer wanted $680,000. Shortfall: $24,000 that has to come from somewhere.

Two options.

• Cover the shortfall in cash. The buyer puts an extra $24,000 down on top of the original deposit and proceeds at 80 percent LVR off $820,000. No LMI. The buyer's cash position is worse by $24,000 at settlement.
• Pay LMI on a higher LVR. The buyer keeps the original deposit and borrows $680,000 against the $820,000 bank val. That is roughly an 83 percent LVR. LMI is payable. On a loan of that size at that LVR band, the premium is roughly $14,000 to $18,000 depending on insurer and term. Call it $16,000 mid-range, capitalised into the loan.

Cash shortfall of $24,000 versus LMI of around $16,000 capitalised. The LMI is cheaper at settlement but accrues interest over the life of the loan. Over 30 years at 6 percent, $16,000 capitalised costs roughly $18,500 in additional interest. Total LMI cost: about $34,500 nominal across the life of the loan, versus $24,000 cash up front.

Third option: spend $800 on an independent registered valuation. If it comes back at $865,000, submit it to the lender and ask for re-instruction. If the lender accepts, the LVR math resets and the original $680,000 loan goes through clean. If the lender refuses, the $800 is gone and the buyer is back to choosing between the cash shortfall and the LMI premium. Probability weighted, the expected value of trying is positive when the gap between the bank val and the contract price is wide enough to justify the spend.

Run the loan and stamp duty sides on the mortgage calculator and the buying cost calculator, and stress-test the LVR scenario before signing the loan documents.

Which figure to ask for, and when

Match the figure to the decision in front of you.

• Buying with a loan: the bank valuation is the only figure that matters for loan approval. The agent appraisal is informational. A registered val is rarely worth the spend unless challenging a short val.
• Selling: the agent appraisal is the starting point. Get two or three from competing agencies and treat the spread as the marketing range. A registered val is not required.
• Refinancing: the bank val will be ordered automatically. Anticipate it; check recent local sales before applying, especially if the market has cooled since purchase.
• Settling an estate, separation, or SMSF audit: registered valuation only. The other two are not accepted.
• Buying off-market or from family: a registered valuation protects both sides from later stamp-duty or ATO disputes about transfer pricing.

For the loan-side decisions in particular, the borrowing power calculator and the companion piece on borrowing power vs serviceability are the right next reads. The pre-approval vs unconditional approval piece explains where in the approval sequence the bank valuation actually lands.

What none of the three will tell you

A valuation values the property. It does not assess the title, encumbrances, easements, or any planning overlay that affects what the owner can do with the land. A valuer assumes the title is clean and the zoning is what the planning instrument says. Verifying both is a separate exercise, handled by the conveyancer and the building inspector. The easements, encumbrances, and caveats piece covers the title side.

On Burbfinder, suburb and region pages surface recent sales, median prices, and price movement so a buyer can sense-check whatever number the bank, the valuer, or the agent has produced. The three figures will rarely agree. They are not supposed to. Reading them as three answers to three different questions is the part that turns the spread into something useful.
