Commercial Property Due Diligence: What Buyers Need to Know

Neil Valentine 20 Oct 2026

Commercial property decisions benefit from careful questions and sound advice. This guide outlines practical considerations for buyers in Victoria, without assuming that any one property or strategy suits everyone.

Why due diligence matters

Commercial properties vary widely in their physical condition, permitted uses, tenancy arrangements and contractual terms. A thorough investigation helps a buyer understand what is being purchased and what obligations may follow.

Title, boundaries and legal interests

Your solicitor can investigate title details, easements, covenants, encumbrances and other interests affecting the property. Where boundaries or improvements are uncertain, a surveyor may be required.

Planning and use

Check zoning, overlays, permits, existing use rights and any constraints on the intended activity. A council planning enquiry or specialist planning advice may be appropriate, especially where a change of use or future development is contemplated.

Leases and income verification

For investments, obtain the executed lease and relevant variations. Review the tenant, term, options, rent, incentives, outgoings, bank guarantees or other security, maintenance obligations and any arrears information available. Independently verify income assumptions with professional assistance. Understanding commercial property leases before you buy covers the questions worth raising.

Physical condition and compliance

Arrange inspections suited to the asset, potentially including building, structural, roof, essential safety measures, electrical, mechanical, environmental or hazardous material assessments. The relevant investigations depend on the building and proposed use.

Financial and operational exposure

Examine operating expenses, rates, insurance, owners corporation information where applicable, capital works, vacancy risk and future expenditure. Ask tax and finance advisers to assess acquisition structure and funding implications.

Contract conditions and timing

Due diligence needs to align with the purchase contract. Do not assume a buyer can withdraw or renegotiate after signing. Obtain legal advice before committing, particularly about conditions, deadlines and remedies.

Coordinating the specialists

A buyer’s advocate can help maintain an organised investigation, identify questions to escalate and coordinate advisers. This does not replace legal, engineering, planning, tax or financial advice. Our process shows where this work sits, and our services describe the wider acquisition engagement.

Making a considered decision

Good due diligence is not a guarantee that every risk disappears. It is a disciplined way to identify material issues, understand uncertainty and decide whether the property still fits the brief.
