Understanding Expression of Interest in Commercial Property

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

An Expression of Interest (EOI) in commercial property is a formal offer to purchase property, indicating interest without binding commitment. It outlines terms like price and conditions but isn't legally binding until formal contracts are exchanged.

An Expression of Interest (EOI) is a critical step in the commercial property acquisition process in Australia. It signals a potential buyer's genuine interest in a property, outlining their offer and terms without initially binding them to a purchase. Unlike a typical purchase contract, an EOI allows for flexibility in negotiations and terms, making it a popular choice for both buyers and sellers in the competitive commercial real estate market.

Under Australian property law, the EOI is not legally binding, meaning that either party can withdraw before formal contracts are signed. This is a common source of confusion, as some investors mistakenly believe an EOI commits them to purchase, similar to a contract of sale. Instead, it serves as a preliminary step to gauge interest and start negotiations. This process can include setting a potential price, deposit amount, and any special conditions the buyer requires, such as due diligence periods or finance approval.

To see how this plays out, consider a scenario where you're interested in a retail space in Melbourne's CBD listed at $1.5 million. You submit an EOI offering $1.45 million, contingent on a 30-day due diligence period and finance approval. The seller reviews your EOI alongside others, choosing to negotiate further with you due to favourable terms. If negotiations proceed well, you'll move to a formal contract, making the EOI a crucial stepping stone in securing the property.

In our experience reviewing thousands of properties across Australia, we've found that EOIs are often misunderstood by new investors. Many fail to realise the importance of clearly defining terms within an EOI, such as specifying the deposit amount and conditions precedent. Another common oversight is not conducting adequate research before submitting an EOI, which can result in unrealistic offers that sellers quickly dismiss. Moreover, EOIs are an opportunity to stand out; a well-drafted document can set you apart from other potential buyers.

The answer can differ depending on your situation. For instance, if you're dealing with a property that has multiple interested parties, the EOI process can become more competitive, requiring a more strategic approach. Additionally, EOIs can vary significantly in complexity and terms when dealing with different property types, such as industrial versus retail spaces. If you're purchasing through a self-managed super fund (SMSF), specific compliance and financial considerations will also come into play.

Given these nuances, obtaining professional advice is crucial. A Chartered Quantity Surveyor can help ensure your offer aligns with market conditions and property values, while a solicitor can verify the legal soundness of your EOI terms. Collaborating with an accountant ensures your financial strategy supports the proposed acquisition effectively.

  • Review the property's details and market conditions thoroughly.
  • Clearly define your terms, including price and conditions, in the EOI.
  • Consult with a Chartered Quantity Surveyor for property valuation insights.
  • Engage a solicitor to review and refine the EOI for legal soundness.
  • Collaborate with an accountant to ensure financial readiness.
  • Submit the EOI and prepare for potential negotiations.
