What Sydney Commercial Property Investors Miss Before They Sign

A commercial property listing tells you what the seller wants you to see. The documents behind it tell you what you are actually buying.

Sydney commercial property is attracting serious investor attention right now. Strong yields, long lease terms, and tenants who cover outgoings — on paper, it looks like a straightforward asset class.

The reality is more complicated. A commercial property listing tells you what the seller wants you to see. The documents behind it tell you what you are actually buying. Before you exchange contracts, there are a handful of risk areas that consistently catch buyers off guard — and that can quietly erode a deal that looked solid at first glance.

Here is what we recommend every investor review before committing.

1. Read the Lease in Full — Not Just the Headline Rent

The rental figure in a listing is a starting point, not a guarantee. To understand what income you will actually collect, you need the signed lease, any amendments, renewal documents, and records of what has actually been paid.

A quoted annual rent may not account for a rent-free period that is still running, a temporary reduction negotiated with the tenant, or outstanding arrears the seller has not resolved. These gaps between the advertised rent and the real income position show up regularly — and they matter enormously for your yield calculation.

Beyond the rent, have your solicitor review the remaining term, renewal options, rent review mechanisms, permitted use, and any early termination rights. An option to extend in the tenant's favour is not guaranteed future income — it is the tenant's right, not yours.

If the property is a retail premises, also confirm whether the NSW Retail Leases Act applies. Retail leases carry specific protections and requirements that cannot be overridden by lease wording, and getting this wrong creates legal exposure from day one.

2. Understand What Outgoings You Can Actually Recover

"Tenant pays outgoings" is one of the most misunderstood phrases in commercial property marketing. A net lease does not mean zero owner expenses — it means some costs are recoverable under the specific terms of that lease. Others stay with you.

For NSW retail leases, the lease and the landlord's disclosure statement must clearly identify the outgoings the tenant is liable for. A broad clause is not enough — you need to see the actual expense categories, the tenant's agreed share, and how recovery is calculated.

Ask for recent council rates, water charges, insurance invoices, management fees, and outgoings reconciliation statements. Compare what has been spent with what has actually been recovered. The gap — if there is one — belongs in your forecast as an owner cost.

Also consider what happens during vacancy. Expenses do not pause when a tenant leaves. Those retained costs need to be modelled into your numbers regardless of how the property is marketed.

3. Calculate Your Own Land Tax Exposure

Do not rely on the seller's land tax bill as a guide to yours. Revenue NSW calculates land tax liability based on the combined taxable value of all NSW land you hold at midnight on 31 December, using unimproved land values averaged over three years — not the purchase price.

Your total portfolio position matters, not just this one property.

Ownership structure adds another layer. Special trusts typically do not receive the land tax threshold, which can significantly increase your liability depending on how you hold the asset. This is a conversation to have with your adviser before you sign, not after.

Under NSW retail leasing rules, the land tax you can recover from a tenant is also limited — it is calculated as though the property were your only landholding, even if it is not. That gap between your actual liability and what you can pass on is your cost to carry.

4. Do Not Overlook Maintenance, GST, and Tenant Security

Three other areas that regularly create surprises:

Maintenance obligations: A tenant's responsibility to service equipment does not extend to replacing it. An ageing HVAC system or a roof that needs work can sit outside the lease obligations and land entirely with you. Get maintenance records and an independent building inspection before you commit.

GST treatment: Whether the sale is GST-free as a going concern depends on specific ATO conditions. Having a tenant in place is not sufficient on its own. Confirm the position with your solicitor and accountant — and make sure your funding plan reflects the confirmed treatment.

Tenant security: Review payment history, the form and amount of any bank guarantee, and what the make-good clause requires when the tenant leaves. Fit-out removal, reinstatement work, and the time needed to relet all affect your real return.
