At first glance, it seems convenient. The agent provides a report, the property looks fine, and the deal moves forward quickly. But this is where costly mistakes happen. A report supplied by an agent or vendor needs the same scrutiny as any other report: who prepared it, when, for what purpose and on what reliance terms? Check unresolved questions with your solicitor, inspector or other relevant professional before committing.
Why Relying on Agent Reports Can Be Risky
The selling agent represents the seller in the transaction. That does not establish that every report they supply is biased or unsuitable; assess the report itself.
Questions to ask about any supplied material include:
What investigation and exclusions does it cover?
Who prepared it and what evidence did they use?
Does it address the risks relevant to your purchase?
Information may be incomplete or outside the report’s agreed scope. Make a list of unresolved questions and identify the professional who can answer each one.
This is why serious buyers complete independent property due diligence before committing.
The Most Common Property Due Diligence Mistakes
1. Assuming the Agent Has Disclosed Everything
One of the biggest misconceptions is that all material risks will be disclosed upfront.
In reality, many issues are:
Unknown to the agent
Outside their expertise
Not required to be proactively investigated
Buyers who rely on this assumption often discover problems after settlement.
2. Skipping an Independent Inspection
Many buyers rely on a basic building report provided during the campaign.
Before relying on one, check:
The inspection and report dates
The available detail and access limitations
Whether it addresses your intended use of the property
A proper inspection aligned to your strategy is critical.
3. Overlooking Structural or Hidden Defects
Some of the most expensive issues are not visible during a standard walkthrough.
These can include:
Structural movement
Water ingress
Poor previous renovations
Non-compliant works
An additional assessment may be appropriate where the existing report does not answer a relevant question.
4. Ignoring Renovation and Cost Risks
Buyers often underestimate how much work a property requires.
What looks like a cosmetic upgrade can turn into:
Major structural rectification
Compliance upgrades
Unexpected cost blowouts
A quantity surveyor may help assess a defined construction or renovation budget. Structural diagnosis and building compliance may require other specialists.
5. Not Understanding the True Value of the Property
Relying purely on the listing price or agent guidance can lead to overpaying.
An independent assessment helps determine:
Market-value evidence at the specified date
The assumptions and limitations affecting the assessment
Potential future costs
This is especially important for investors.
What Proper Property Due Diligence Should Include
A comprehensive due diligence process should cover:
Independent property inspection
Risk identification and defect analysis
Cost estimation for repairs or upgrades
Depreciation insights for investors
Market and value assessment
Together, appropriately scoped reports can reduce uncertainty. They do not identify every possible issue. Check unresolved questions with your solicitor, inspector or other relevant professional before committing.

Frequently Asked Questions
What is property due diligence in Australia?
Property due diligence involves independently assessing a property’s condition, risks, value, and costs before purchasing.
Do I need an independent property report if the agent provides one?
Check the author, commissioning party, date, scope, exclusions and reliance terms. A vendor-supplied report may be useful, but ask the relevant professional or your adviser whether further work is needed for your purchase.
What reports should I get before buying a property?
This may include a building inspection, pest inspection, quantity surveyor report, and valuation depending on the property and strategy.
Can due diligence save money when buying property?
Yes. Identifying issues early can help you negotiate price, avoid costly mistakes, or walk away from a bad deal.
Final Thoughts
Relying solely on agent-provided information may seem easier in the short term.
