A property valuation is only as reliable as the evidence and judgement behind it. In Melbourne, where a single suburb can contain Victorian terraces, 1970s units and new townhouses, those inputs vary widely from one property to the next.
Knowing what drives valuation accuracy helps owners, lawyers and accountants assess a report and provide the right information from the start.
For Melbourne and regional Victorian properties, five factors carry the most weight: comparable sales, the inspection, planning and title, timing, and the valuer's independence and instructions.
What does valuation accuracy mean?
A valuation is an independent opinion of market value at a stated date. Market value is broadly the price a property would likely achieve between a willing buyer and a willing seller in an arm's-length sale after proper marketing.
Accuracy does not mean predicting a precise sale price. It means the opinion is well supported, uses an appropriate method, reflects the property as it really is and can stand up to scrutiny from a court, the ATO or the State Revenue Office.
When accuracy matters most
Accuracy carries particular weight when a valuation is used for:
Family law property settlements
Capital gains tax, including converting a home to a rental
Duty on related-party transfers in Victoria
Deceased estates and distributions between beneficiaries
SMSF annual reporting
Property litigation and expert evidence
The 5 factors that affect accuracy
1. Quality of comparable sales evidence
Comparable sales are the backbone of most residential valuations. The valuer identifies recent, similar sales and adjusts for differences in land, building, location and condition.
Evidence depth varies across Melbourne. A four-bedroom home in Point Cook or Craigieburn may have many recent comparable sales. A large period residence in Kew, Toorak or Canterbury may have only a handful each year. Thin evidence calls for wider searches and larger adjustments, which places more weight on the valuer's expertise.
2.Inspection and property condition
Melbourne's older housing stock makes the inspection especially important. An Edwardian weatherboard in Coburg might be fully restumped and extended, or still in original condition. Those differences rarely appear in sales records.
The valuer also notes defects, unapproved works and anything that would concern a typical buyer.
3. Planning, zoning and title matters
Victoria's planning schemes use zones and overlays that directly affect what owners can do. A Melbourne valuer may consider:
The residential zone, such as the Neighbourhood Residential Zone or General Residential Zone
A Heritage Overlay, which can control demolition and alterations
A Land Subject to Inundation Overlay along waterways such as the Maribyrnong
A Bushfire Management Overlay in parts of the outer east and the Dandenong Ranges
Easements, covenants and restrictions on title
Owners corporation rules, fees and any building rectification works, such as combustible cladding
An overlooked overlay or covenant can materially change the value of the land.
4. Markettiming and the valuation date
A valuation reflects the market on its valuation date. Melbourne's market has moved differently from other capitals in recent years, and conditions can shift between suburbs and property types. A report prepared months ago may no longer reflect current values.
For a retrospective valuation, such as a CGT value at the date a home first became a rental, the valuer must rely on evidence from that historical date.
5. Valuer independence and clear instructions
Accuracy also depends on who prepares the report and what they were asked to do. The valuer should be an independent Certified Practising Valuer with no stake in the outcome. The purpose, valuation date and basis of value should be agreed in writing before the inspection.
What owners can do to support an accurate valuation
Useful information for a Melbourne valuation often includes:
The purpose and the required valuation date
Building permits and occupancy certificates for extensions
Renovation invoices, plans and photographs
Owners corporation certificates, minutes and fee notices for units
Current leases and rental details for investment properties
Details of any planning permits, disputes or known defects

When two valuations differ
When two Melbourne valuations of the same property disagree, start by comparing the valuation dates, the basis of value, the sales relied on and the assumptions made. Many differences trace back to different instructions.
If the gap is significant, a solicitor can advise whether a review, a further report or a jointly appointed valuer is the right next step.
Example: one Melbourne townhouse,two differentfigures
Consider a three-bedroom townhouse in Box Hill North held by a self-managed super fund. The trustees obtained a valuation two years ago and now need a current market value for the fund's annual reporting. The new figure is noticeably different, and the fund's auditor asks why.
On review, the difference traces back to three of the five factors. The earlier report was prepared at a different point in the market cycle, when buyer demand for medium-density housing in the area was weaker. It relied on sales of older units rather than comparable townhouses, because few townhouse sales had occurred at the time. And since then, the owners corporation has completed waterproofing works that had previously been flagged as a defect, which the new inspection recorded.
Neither report was wrong. Each reflected the evidence and condition at its own date. But the trustees need the current report, because the auditor is checking the value at the end of the financial year, not two years earlier.
This example shows why the date, the evidence available and an up-to-date inspection matter as much as the valuer's skill. It is also why trustees should keep earlier reports on file, so any change in value can be explained clearly to the auditor.
Common reasons a valuation is questioned
A Melbourne valuation is most often queried because:
The comparable sales were not genuinely similar in type, size, quality or location
An extension, outbuilding or second dwelling was missed or wrongly recorded
A zone, overlay or restrictive covenant was overlooked
The valuation date did not match what the solicitor, accountant or auditor needed
The report was prepared for another purpose, such as mortgage security
Owners corporation issues, cladding works or a tenancy were not taken into account
Most of these can be avoided by giving the valuer clear written instructions and complete information from the start. If a report has already been questioned, a short written request to the valuer, with supporting documents attached, is usually the quickest path to resolution.
Frequently asked questions
Why is my valuation differentfrom the CIV on my rates notice?
The Capital Improved Value is a statutory valuation prepared each year for rating, as at 1 January. A market valuation is prepared for a specific purpose and date after an individual inspection, so the two figures often differ.
Do planning overlays always reduce value?
Not always. A Heritage Overlay can limit redevelopment but may support values in established streetscapes. The effect depends on the property and local market.
Do owners corporation issues affect apartment valuations?
They can. Special levies, building defects and rectification works may influence what buyers will pay and should be disclosed to the valuer.
How long is a valuation report valid?
A valuation is generally current only at its valuation date. If the market or the property changes, an updated report may be needed. Check with the party relying on it.
Can I ask a valuer to reconsider their figure?
Yes, if you have factual corrections or relevant information the valuer did not have, such as permits, plans or a more comparable sale. The valuer will consider it. However, the opinion of value is theirs to form independently, and a difference of view alone does not oblige them to change it.
What qualifications should a Melbourne valuer hold?
Look for a Certified Practising Valuer registered with the Australian Property Institute, with professional indemnity insurance and experience in your property type.
