Commercial Conveyancing vs Residential

On the surface, buying or selling a commercial property looks similar to a residential transaction. There is a contract of sale, a settlement period, and a conveyancer or solicitor managing the transfer. Underneath that surface, however, commercial conveyancing involves a different set of considerations around tax, tenancy and due diligence that do not usually arise in a standard home purchase. Anyone moving from residential property into commercial, whether as an investor or a business owner buying their own premises, benefits from understanding these differences before signing a contract.

GST Implications on Commercial Sales

Residential property sales between private individuals are generally free of GST, but commercial property sales frequently are not. Whether GST applies, and at what rate, depends on factors including whether the vendor is registered for GST, whether the property is tenanted under an existing lease, and whether the sale qualifies to be treated as a going concern. A supply of a leased commercial property sold as a going concern can be GST-free under specific conditions, as set out in the ATO's guidance on selling a going concern, but getting the contract wording and the parties' GST registration status right is essential, since an incorrect assumption here can materially change the effective price of the transaction for either party. This is one of the clearest differences from a residential purchase, where GST rarely enters the conversation at all.

More Extensive Due Diligence on Zoning and Permitted Use

Residential buyers mostly care whether a property is structurally sound and legally able to be occupied as a home. Commercial buyers need to dig further, confirming that the zoning of the property permits the specific use they intend, whether that is retail, industrial, office or something more specialised such as a childcare centre or medical practice. Council records, planning overlays and any existing permits need to be checked carefully, because a property that looks suitable can still be legally restricted from the use a buyer has in mind. This due diligence typically takes longer and involves more documentation than the equivalent checks on a home, and it needs to happen well before the buyer commits to unconditional finance.

Lease Review and Tenant Disclosure Obligations

Many commercial properties are sold with an existing tenant in place, and reviewing that lease becomes a central part of the due diligence. Key details include the remaining term, any option periods, rent review mechanisms, outgoings arrangements, and whether the tenant has a right of first refusal or any other clause that could affect the buyer's plans. Retail leases in particular are subject to specific state-based disclosure obligations that do not apply to standard commercial leases, and getting this wrong can expose a buyer to unexpected obligations toward the tenant after settlement. None of this has an equivalent in most residential transactions, where a tenanted home sale involves a comparatively simple lease that transfers with minimal complexity.

Different Adjustment Items at Settlement

Settlement adjustments on a residential purchase are usually limited to council rates, water charges and sometimes body corporate fees. Commercial settlements often carry a longer list, including outgoings recovery from tenants, land tax adjustments, and sometimes GST components built into the settlement figures. Where a property is tenanted, the buyer typically needs to account for rent already collected by the vendor for a period extending past settlement, and outgoings the vendor has paid in advance that the buyer now needs to reimburse. Working through these figures accurately is a more involved exercise than the equivalent step in a residential settlement, and errors here can affect cash flow for a new owner from day one.

Why Commercial Matters Take More Preparation Time Upfront

Settlement periods for commercial property often look similar on paper to residential ones, frequently 30, 60 or 90 days from exchange. What differs is how much preparation needs to happen in that window, or ideally before contracts are even exchanged. Reviewing a lease, confirming GST treatment, checking permitted use and working through outgoings adjustments all take longer than the equivalent residential checks, which is why experienced commercial buyers and their advisers tend to start due diligence earlier relative to the settlement date rather than compressing it into the final weeks. Reviewing the contract of sale carefully at the outset, rather than treating it as a formality, is especially important in a commercial deal because special conditions here carry more financial weight than they typically do in residential contracts.

When You Need Commercial-Specific Experience

Not every property transaction with a business use requires a specialist. A small strata-titled office purchased outright with no tenant in place is closer in complexity to a residential purchase than a large tenanted industrial site with multiple lease arrangements and land tax considerations. As a general guide, the more that GST treatment, tenancy arrangements or zoning compliance are live issues in the transaction, the more valuable it is to work with a conveyancer who regularly handles commercial purchase and commercial sale matters, rather than someone whose experience sits mainly in residential settlements.

This matters regardless of location, though the specific state-based rules around retail lease disclosure, land tax and duty concessions vary. A commercial purchase in New South Wales will involve different disclosure requirements to one in another state, even though the underlying due diligence categories, GST, zoning, leases and adjustments, remain broadly the same across the country.

Talking to a Conveyancer Before You Commit

If you are considering a commercial purchase or sale for the first time, raising these questions with a conveyancer before you sign anything gives you time to understand the GST position, review any lease properly, and confirm zoning compliance while there is still room to negotiate contract terms. Commercial transactions reward early preparation more than residential ones do, simply because there is more to check and more that can go wrong if it is left until the final weeks before settlement.
