Due diligence in a real estate transaction means the checks and investigations a buyer completes before committing to purchase. In Victoria, this includes reviewing the contract and Section 32, checking title restrictions, zoning and planning controls, arranging building and pest inspections, and confirming finance to avoid legal, financial, or usability risks.
At Red Door Conveyancing, we believe informed clients make better decisions. This article explains what due diligence means in a real estate transaction, what it involves, and how it protects you when buying property in Melbourne and across Victoria.
When Should Due Diligence Be Done?
The timing around when due diligence should be completed differs based on whether the property is purchased at auction or through private sale. For properties purchased at auction, the contract becomes unconditional once the hammer goes down. As such, due diligence such as having a contract reviewed, obtaining finance approval and completing building and pest inspections should be done prior to auction.
For properties purchased through a private sale, due diligence can be partly completed before contract signing and finalised after the contract has been signed. A contract review is always recommended prior to contract signing and special conditions for finance approval and building and pest inspections can be negotiated before/ on contract signing.
In this instance, a date is agreed between the purchaser and seller for when these items must be completed. The purchaser can exit the contract without losing their deposit if they are declined for finance by the agreed date, or if a major structural defect is discovered by the agreed date.
However, once these dates lapse, the contract is unconditional and the purchaser must go through with the sale regardless of what is identified after this.
Why Is Due Diligence So Important?
Once a contract becomes unconditional, the buyer is legally bound to proceed. Failing to carry out proper due diligence can result in:
- Unexpected legal restrictions
- Costly repairs or compliance issues
- Inability to develop or renovate as planned
- Financial loss if the property cannot be used or sold as expected
Thorough due diligence helps ensure there are no unpleasant surprises after settlement.
What Does Due Diligence Typically Involve?
Due diligence can vary depending on the property type, location, and buyer intentions. However, in Victoria it commonly includes the following:
1. Reviewing the Contract of Sale and Section 32 Statement
The Section 32 (Vendor’s Statement) is a legally required disclosure document in Victoria. It provides essential information about the property, including:
- Title details and ownership
- Easements, covenants, and restrictions
- Zoning and planning information
- Outgoings such as council rates and water rates
- Owners corporation details (if applicable)
A conveyancer reviews these documents to identify red flags that may not be obvious to the buyer.
2. Title Searches and Property Restrictions
Due diligence involves confirming that the seller legally owns the property and identifying any restrictions, such as:
- Easements (e.g. drainage or access rights)
- Restrictive covenants (limiting building or land use)
- Mortgages or caveats on title
These issues can affect what you can do with the property and may impact future value.
3. Planning, Zoning and Council Searches
Council and planning checks are particularly important in Victoria, where zoning and overlays can significantly affect development potential.
These searches may reveal:
- Zoning limitations
- Heritage, environmental, or flood overlays
- Proposed roadworks or nearby developments
For buyers intending to renovate, subdivide, or build, this step is essential.

4. Building and Pest Inspections
Legal due diligence should be complemented by physical inspections, including:
- Building inspections
- Pest inspections
- Compliance checks for renovations or extensions
These inspections can uncover structural issues or safety concerns that may not be visible during an open inspection.
5. Owners Corporation Review (Apartments & Townhouses)
If purchasing a property with an owner’s corporation, due diligence includes reviewing:
- Owners’ corporation certificate
- Financial statements and budgets
- Special levies
- Rules and restrictions
This helps buyers understand ongoing costs and any upcoming expenses.
6. Finance and Lending Approval
Ensuring your finance is in order forms part of your due diligence. This includes:
- Confirming loan approval conditions
- Understanding lender requirements
- Ensuring settlement timelines can be met
Failing to do so can result in penalty interest or loss of deposit.
Who Is Responsible for Due Diligence?
Ultimately, the buyer is responsible for ensuring due diligence is completed. However, a qualified conveyancer plays a crucial role by:
- Reviewing legal documents
- Explaining risks in plain English
- Ordering and interpreting searches
- Advising on next steps
