Property Valuation in Brisbane: Bank, Independent and Online Estimates Explained
A property valuation in Brisbane is a professional estimate of what a property would sell for between a willing buyer and seller. The one that matters most when you buy is the bank valuation, because your lender uses it, not the price you agreed, to decide how much it will lend.[1][2]
Buyers meet several different “values” for the same house: the lender’s valuation, an independent valuation, an online estimate and the selling agent’s view. They are done by different people for different reasons, so they rarely agree. This guide explains each one, what Queensland’s rules say about them, and what to do when the bank’s number comes in below your price.
Key takeaways
- A bank valuation is done for the lender, which uses the property as security for your loan.
- An independent valuation in Queensland comes from a valuer registered with the Valuers Registration Board, and you can check the register.
- Online estimates are produced by algorithms. They come with a confidence measure and are a guide, not a valuation.
- In Queensland, price guides are illegal for auction properties, and an agent’s market analysis is not a valuation.
- If the bank values below your price, the shortfall usually comes from your own funds, more lenders mortgage insurance, or a renegotiation.
The kinds of property value you will see
The table sets out who produces each figure and what it is for. Most confusion about valuations comes from treating one of these as if it were another.
| Figure | Who produces it | What it is for |
|---|---|---|
| Bank valuation | A valuer engaged by your lender | Checking the property is enough security for the loan[2] |
| Independent valuation | A Queensland registered valuer you engage | Your own professional opinion of value[3] |
| Online estimate | An automated valuation model (an algorithm) | A quick guide, with a confidence measure[4] |
| Comparative market analysis | The selling agent | Advising the seller, for example on an auction reserve[5] |
| Land valuation | The Valuer-General | The basis for land tax, valuing the land only[7] |
Bank valuations: done for the lender
Before your loan is fully approved, your lender may send a valuer to the property. It does this because the property is the security for the loan, and it wants to know the security covers what it is lending.[2] That is also why pre-approval is not the end of the process. The lender still assesses the property itself before it gives final approval.[8]
Westpac describes a bank valuation as the value of the property as decided by the lender, often using an independent valuer. It weighs recent sales of similar properties in the area, location, zoning, land size and the condition of the building, and a valuation is sometimes done from the street without going inside.[1]
Two things follow from that. First, the valuation answers the lender’s question, not yours: it is not a verdict on whether you are paying too much. Second, a valuation done from the street cannot credit a renovation it cannot see. Give the valuer’s office any information that helps, such as recent comparable sales and a list of improvements, through your broker or lender.
You can also engage a valuer yourself. In Queensland, valuers are registered with the Valuers Registration Board of Queensland under the Valuers Registration Act 1992. Registration to value land in Queensland must be renewed each year, and the Board publishes a register you can search before you engage anyone.[3]
An independent valuation is useful when you want your own professional opinion before you commit. Examples are an unusual property with few comparable sales, a purchase from family, or checking a bank valuation that seems out of step with the market. The Queensland Government suggests getting a property valuation before you bid at an auction.[6] Ask for a written quote before the valuer starts, and confirm the report is addressed to you.
The values on property websites and bank apps come from automated valuation models. PropTrack, whose estimates appear on realestate.com.au, describes its model as an algorithm that instantly produces a value estimate. It mirrors a valuer’s approach by assembling similar properties and drawing on sales history and listings.[4]
Each estimate comes with a measure of confidence. PropTrack calls it the forecast standard deviation: the lower it is, the more reliable the estimate, and the higher it is, the more uncertain.[4] Read the range and the confidence level, not just the headline number. Expect wide ranges for character homes, acreage, recently renovated houses and suburbs with few sales, where there is less data to work from.
The selling agent’s figure is a different thing again. If a seller wants advice on an auction reserve, Queensland requires the agent to give them a comparative market analysis comparing at least 3 properties of similar standard or condition, sold within 5 km in the last 6 months.[5] It is prepared for the seller, and buyers see it only with the seller’s approval.[6]
For auctions, it is illegal for the seller or their agent to give you a price guide. A price range you see when searching a listings website is a search setting, not a guide.[6] So at auction, your own research on comparable sales is what tells you what a property is worth. Our guide to vendor bids at auction explains what the auctioneer’s announcements do and do not reveal.
A low valuation changes your loan-to-value ratio, the size of the loan compared with the property’s value. Lenders work it out on the bank valuation, and above 80% they usually require lenders mortgage insurance.[2] A worked example shows why it matters:
| Step | Amount[2] |
|---|---|
| Agreed price | $800,000 |
| Your 20% deposit | $160,000 |
| Loan you applied for | $640,000 |
| Bank valuation | $760,000 |
| Loan-to-value ratio on the valuation | 84% |
| Loan that keeps you at 80% of the valuation | $608,000 |
| Extra money needed to stay at 80% | $32,000 |
The property has not lost value overnight. The lender has simply decided it will lend against its valuation, not your price. Your options, in the order most buyers try them:
- Find the difference. Westpac suggests topping up the deposit, using equity in a property you already own, or having someone act as guarantor.[1] Our guide to usable equity explains how equity is worked out.
- Accept a higher loan-to-value ratio. The loan can still go ahead with lenders mortgage insurance, which can sometimes be added to the loan if you can service the larger amount.[2] Our guide to the costs of buying a house in QLD covers mortgage insurance alongside the other costs.
- Renegotiate the price. A valuation is evidence. If the comparable sales support a lower figure, it can reopen the conversation with the seller, especially while your contract is still conditional.
- Ask your broker about the valuation itself. If the comparable sales used look wrong, your broker or lender can ask for them to be reviewed.
Timing matters. A conditional offer becomes binding only if its conditions, such as valuation and finance approval, are met.[8] If a valuation comes in low, speak to your solicitor before your finance date, not after it. At auction there are no conditions, so get your own view of value before you bid.
A buyer’s agent prices a property the way a valuer does, from comparable sales, but on your side and before you commit. As part of our buyer’s agent services, we compare the property with recent sales of similar homes nearby, adjust for differences in land, condition and position, and set a limit with you that the evidence supports. That gives you a figure to negotiate from and an early warning when a price is out of step with what a bank is likely to lend on.
A recent example: a first-time investor bought 9 Clementine Place, Bli Bli, off-market in March 2026 for $943,786. On 26 August 2026 the client’s bank revalued it at $1,025,000, a difference of $81,214 or 8.61%. That is a bank valuation, not a sale price, and no promise of future value. The full story is in the Bli Bli success story. We work across Brisbane, the Sunshine Coast and the rest of South East Queensland, and our Brisbane suburb reports are a starting point for local comparisons.
Owners also receive an annual land valuation from the Valuer-General. It values the land, and it is the basis of the taxable value used for land tax.[7] It is not a valuation of the house for a sale or a loan, so do not compare it with a bank or independent valuation.
Online estimates and agents’ figures are a starting point. The bank valuation decides your loan, and a registered valuer’s report is the only one written for you. Work out your own value from comparable sales before you offer, and keep enough room in your budget for a valuation that comes in short.

Is a bank valuation the same as market value?
Not exactly. A bank valuation is the value of the property as decided by your lender, usually through a valuer it engages, and it exists to check the property is enough security for the loan. It draws on recent comparable sales like any valuation, but it answers the lender’s question, so it can come in below the price a buyer was willing to pay.
What happens if the bank valuation is lower than the purchase price?
Your lender works out the loan-to-value ratio on the lower valuation, so you may need more of your own money, a guarantor or equity from another property, or you may have to pay lenders mortgage insurance. You can also try to renegotiate the price. If your contract is conditional, talk to your solicitor before the finance date.
Are online property value estimates accurate?
They are a useful guide but not a valuation. They are produced by algorithms from comparable sales, sales history and listings, and each comes with a confidence measure. Check the range and the confidence level rather than the single number, and expect less reliable estimates for unusual or recently renovated homes.
Can a real estate agent give me a valuation?
A selling agent can give the seller a comparative market analysis, which in Queensland must compare at least three similar properties sold within 5 km in the last six months when it is used to advise on an auction reserve. It is prepared for the seller and is not a formal valuation. For a valuation of your own, use a registered valuer.
How do I find a registered valuer in Queensland?
Valuers in Queensland are registered with the Valuers Registration Board of Queensland, which publishes a register you can search online. Registration must be renewed every year, so check the valuer is currently listed, ask for a written quote, and make sure the report will be addressed to you.
Is the land valuation on my notice what my house is worth?
No. The annual land valuation from the Valuer-General values the land and is the basis of the taxable value used for land tax. It is not a valuation of your house for a sale or a loan, so it should not be compared with a bank or independent valuation.
