For a commercial buyer, settlement is the moment the deal stops being a contract and becomes an income-producing asset on the buyer's balance sheet. Everything negotiated during the campaign and tested during due diligence is crystallised on one date: title transfers, the bank advances funds, the existing lease comes across with its tenant and its income, and the adjustments are finalised to the cent. Done well, settlement is quiet and unremarkable. Done poorly, it becomes the point where an over-renting problem, a defective lease assignment, or an unexpected GST liability surfaces with no way to walk back.
What the buyer is really acquiring at a commercial settlement is not just land and a building. It is a contractual income stream attached to a tenant covenant, plus a basket of statutory and tax obligations that change hands at the same time. The mechanics differ from a residential purchase in several material ways: the lease and its tenant must be properly transferred, the outgoings have to be apportioned, the GST treatment must be settled in advance, and security held over the tenancy (a bank guarantee or bond) has to move from vendor to buyer. Getting each of these right is the difference between collecting clean rent from day one and inheriting a dispute.
This guide walks through the end-to-end commercial settlement process in Australia from exchange to completion, the buyer-side tasks that determine whether settlement is smooth, and the failure points that most often cause delay or loss. It assumes a standard tenanted commercial investment; syndicated, strata, and development purchases add their own layers.
Residential settlement transfers a property; commercial settlement transfers a business arrangement. The lease, the tenant covenant, the security deposit and the tax treatment all change hands on the same day, and any one of them can derail the rest.
From exchange to settlement: the commercial timeline
Commercial settlement periods in Australia are typically longer than residential, commonly 30 to 90 days, and sometimes longer where finance, lease assignment, or a going-concern arrangement needs time to organise. The clock starts at exchange (also called contract formation), when both parties sign and the deposit is paid. From there the contract usually runs through a finance period, then a due diligence period, before becoming unconditional and proceeding to settlement.
The buyer should treat the period between exchange and settlement as an active project, not a waiting room. Lender valuations, lease verification, searches and the GST decision all have to be completed inside the window, and several of them depend on documents the buyer can only obtain from the vendor or the tenant. A close review of the commercial contract of sale at the front end determines what protections the buyer actually has if any of these steps go wrong.
The deposit and conditions
The deposit on a commercial contract is commonly 10 per cent, though it is negotiable and is sometimes reduced or released early to the vendor by agreement. It is usually held in the selling agent's or the vendor solicitor's trust account, or provided as a deposit bond. The deposit is the buyer's principal capital at risk if the contract becomes unconditional and the buyer then fails to complete, so the conditions that protect it matter:
- Finance condition: makes the contract subject to the buyer obtaining acceptable loan approval by a set date. Commercial lending is assessed differently from residential, weighing the lease covenant and income as much as the borrower, so this period must be realistic.
- Due diligence condition: a defined period to complete searches, building and environmental inspections, and lease review. Whether this is a broad satisfaction clause or a narrow one shapes the buyer's ability to exit.
- Special conditions: tailored items such as a satisfactory tenant estoppel certificate, confirmation of the GST treatment, or assignment of warranties. These are where a sharp buyer's lawyer earns the fee.
1 The role of the conveyancer and solicitor
Most commercial buyers engage a solicitor rather than a conveyancer, because commercial contracts carry lease, tax and corporate questions that sit beyond standard conveyancing. The lawyer runs the legal side of settlement: reviewing the contract and disclosure, ordering and interpreting searches, raising and answering requisitions, verifying the lease and security, settling the adjustment figures with the vendor's representative, and attending the electronic settlement.
The buyer's agent and the solicitor work in parallel. The agent (the buyer's advocate) typically manages the commercial logic — testing market rent, covenant strength, and the assumptions in the seller's WALE — while the solicitor converts that into protective contract terms and a clean transfer. Independence matters at this stage: a buyer's representative who is not taking a fee from the selling side has no incentive to wave through a weak lease or a soft adjustment.
2 Lease assignment, estoppel and lessor's certificates
In a tenanted purchase, the buyer steps into the landlord's shoes under each existing lease. The income the buyer is paying for depends entirely on those leases being valid, current, and assignable, which is why lease verification is the heart of commercial settlement and a core part of due diligence.
Estoppel certificates
An estoppel certificate (sometimes called a tenant acknowledgement or lessor's certificate) is a statement signed by the tenant confirming the key facts of the tenancy as at settlement: that the lease is on foot, the current rent and review date, the expiry and any options, the security held, that no rent is prepaid beyond the current period, and that neither party is in default. It protects the incoming landlord from later being told the rent was lower, an incentive was outstanding, or the tenant had a dispute that pre-dated settlement. Obtaining estoppels from material tenants before completion is a standard buyer-side condition; their absence is a reason to slow settlement, not speed it.
What the buyer should confirm on each tenancy
- Lease and variations: the executed lease plus every amendment, side deed and rent-review memorandum, not just a summary.
- Rent and reviews: the passing rent, the next review type and date, and whether any review is unactioned. Watch for passing rent sitting above market.
- Term and options: expiry, option periods, and whether options have been validly exercised, since these drive the weighted lease term.
- Incentives and arrears: any unamortised incentive, rent-free period or outstanding arrears that should be adjusted or disclosed.
- Security: the form and amount of any bank guarantee or bond, and how it transfers.
3 Adjustment of rent and outgoings at settlement
On the settlement date, income and expenses are apportioned between vendor and buyer so each party bears only the days it owns the asset. This adjustment is calculated on a statement of adjustments prepared by the parties' representatives and reconciled before completion.
The vendor is credited for amounts it has paid that relate to the buyer's period of ownership (for example council and water rates, land tax where recoverable, and insurance paid in advance), and the buyer is credited for rent the vendor has already received that relates to the post-settlement period. Because commercial leases often pass outgoings through to tenants, the adjustment also has to account for what the tenant has paid or will reimburse, so the buyer is not double-charged. Getting the apportionment of recoverable versus non-recoverable outgoings right is where net yield is quietly protected or eroded.
| Item | Typically adjusted in favour of | Buyer-side check |
|---|---|---|
| Rent (paid in advance) | Buyer (for post-settlement days) | Confirm against the rent roll and bank receipts, not the IM |
| Council and water rates | Vendor (if prepaid) | Verify the current assessment and any arrears |
| Land tax | Depends on state and recoverability | Check single-holding basis and retail-lease restrictions |
| Outgoings recovered from tenant | Reconciled | Match to the lease and the latest reconciliation |
| Tenant arrears / prepayments | Case by case | Confirm via the estoppel certificate |
4 GST at settlement: going concern versus taxable supply
GST is the single most consequential tax decision at a commercial settlement, and it has to be resolved before completion, not after. The sale of commercial property is generally a taxable supply, which means GST of 10 per cent may apply to the price. The most common way to avoid funding that GST at settlement is the going-concern exemption, where a tenanted commercial property sold with its lease in place can qualify as the supply of a going concern and be GST-free, provided both parties are registered for GST, they agree in writing before settlement that the supply is a going concern, and the vendor carries on the enterprise until completion.
The detail matters because the consequences are large. If the parties assume going concern but the conditions are not met, the price may be treated as GST-inclusive or the vendor may pursue an additional 10 per cent, and the buyer may face a stamp duty calculation on a GST-inclusive figure. Where the margin scheme or a fully taxable treatment applies instead, the input-tax-credit position changes. Buyers should resolve the treatment as a contract condition and take advice; for the underlying mechanics see the detail on GST on commercial property. This is general information only and not tax advice.
5 PEXA, stamp duty and electronic settlement
Most Australian property settlements now complete electronically through PEXA (Property Exchange Australia), the national e-conveyancing platform. The parties' representatives and the incoming lender meet in a digital workspace where the transfer is lodged, funds are disbursed, and title is updated, usually within a single coordinated transaction on the settlement date. Electronic settlement reduces some traditional risks (lost cheques, no-show parties) but adds new ones: every party must be onboarded, the workspace must balance to the cent, and a single unverified figure can hold the line.
Transfer duty (stamp duty) is generally calculated and paid through the workspace as part of completion. Commercial duty is assessed by each state and territory revenue office and is a significant transaction cost that the buyer funds at settlement; the rate and base vary by jurisdiction and by whether the price is GST-inclusive. Buyers should model duty early using the relevant state stamp duty schedule and confirm the dutiable value, since an unexpected duty figure is a common cause of a last-minute shortfall in cleared funds.
6 Transferring bank guarantees and security bonds
The security a tenant lodges against its obligations — most often a bank guarantee, sometimes a cash bond or a personal or directors' guarantee — does not transfer automatically. A bank guarantee is usually issued in favour of the named landlord, so on a change of ownership it generally has to be reissued in the buyer's name, which the tenant's bank must arrange and which takes time.
If the security is not properly transferred at settlement, the buyer may complete the purchase holding no enforceable security over the tenancy it just paid for. The standard approach is to make delivery of a fresh guarantee (or assignment of the existing one) a settlement requirement, and to confirm the amount and form against the lease and the estoppel. Cash bonds are adjusted as a credit, and any personal guarantees should be documented as continuing or replaced.
7 What can go wrong and delay settlement
Most commercial settlement failures trace back to something that should have been resolved earlier. The recurring causes:
- Finance not ready: the lender's valuation comes in low, or the credit assessment of the lease covenant takes longer than the finance period allows.
- Lease and estoppel gaps: a tenant will not sign an estoppel, a variation is missing, or the lease turns out not to be validly assignable.
- GST surprises: a going-concern assumption fails its conditions, changing the funds required.
- Security not reissued: the tenant's bank cannot reissue the guarantee in time.
- Title defects: a caveat, easement or unregistered dealing emerges on a search.
- Adjustment disputes: the parties cannot agree the statement of adjustments, often over land tax or an outgoings reconciliation.
- Funds and workspace: cleared funds fall short (commonly because duty or a shortfall was under-modelled) or a PEXA party is not onboarded.
Where a buyer cannot complete on the due date, the contract usually allows the vendor to serve a notice to complete and, ultimately, to terminate and forfeit the deposit. That is why the buyer-side discipline is to resolve every conditional item early and treat the settlement date as immovable. Structures such as an SMSF with an LRBA add further timing and documentation requirements that need to be sequenced well before completion.
The buyer-side settlement checklist
- Finance unconditional with the valuation confirmed and funds scheduled.
- Leases verified in full, with executed estoppel certificates from material tenants.
- GST treatment agreed in writing and the consequence modelled.
- Statement of adjustments reconciled line by line against source documents.
- Security in order — bank guarantees reissued, bonds adjusted, guarantees documented.
- Searches clear and any caveat or encumbrance dealt with.
- Stamp duty and cleared funds confirmed and the PEXA workspace balanced.
Commercial settlement rewards preparation. The buyers who complete cleanly are the ones who treated the lease, the tax, the security and the adjustments as live tasks from the day of exchange, and who had independent representation testing each figure rather than accepting the seller's version of the asset.
Frequently Asked Questions
How long does a commercial property settlement take in Australia?
Commercial settlement periods are typically 30 to 90 days from exchange, longer than most residential purchases. The exact period is negotiated in the contract and depends on the time needed to arrange finance, verify and assign leases, and resolve the GST treatment. Tenanted and going-concern purchases usually sit at the longer end.
What is a tenant estoppel certificate and why does it matter at settlement?
An estoppel certificate is a statement signed by the tenant confirming the key facts of the lease as at settlement, such as the current rent, review and expiry dates, the security held, and that neither party is in default. It protects the incoming landlord from later claims that the income or terms were different. Obtaining estoppels from material tenants before completion is a standard buyer-side condition.
Do I pay GST when buying a tenanted commercial property?
The sale of commercial property is generally a taxable supply, so GST of 10 per cent can apply. A tenanted property sold with its lease in place may instead qualify as a GST-free going concern if both parties are registered, agree in writing before settlement, and the vendor carries on the enterprise until completion. The treatment must be resolved before settlement and confirmed with a tax adviser.
What happens to the tenant's bank guarantee when ownership changes?
A bank guarantee is usually issued in favour of the named landlord and does not transfer automatically, so it generally has to be reissued in the buyer's name by the tenant's bank, which takes time to arrange. Buyers should make delivery of a fresh guarantee a settlement requirement so they are not left holding no enforceable security after completion. Cash bonds are adjusted as a credit at settlement.
