Commercial Property Lease Due Diligence: 9 Tenant and Lease Risks to Check

Author : Make My Property | Published On : 14 Nov 2026

Commercial property lease due diligence is an important part of assessing an investment before signing a purchase contract. A property may show strong rental income on paper, but unpaid rent, weak tenant arrangements, upcoming lease expiry or unexpected maintenance obligations can affect its actual investment performance.

For commercial property investors in Australia, reviewing the lease is just as important as assessing the building, location and asking price. A signed lease does not automatically guarantee reliable rental income. Investors need to check the tenant's legal identity, payment history, lease conditions and responsibilities before committing their capital.

Here are nine important tenant and lease checks that can help identify risks before acquiring a commercial investment property.

Why Is Commercial Property Lease Due Diligence Important?

Commercial property lease due diligence helps investors verify the rental income, understand contractual obligations and identify risks that may affect future returns. It also provides a clearer picture of the property's current tenancy position and ongoing ownership responsibilities.

A proper review should cover the following nine areas:

Tenant legal entity and financial strength.
Rental arrears and payment history.
Remaining lease term and expiry.
Renewal options and termination rights.
Rental reviews and increase clauses.
Rental incentives and landlord contributions.
Outgoings and expense recovery.
Maintenance and repair responsibilities.
Permitted use, assignments and subleasing.

Investors should have an Australian commercial property solicitor review the lease and explain any legal obligations before proceeding.

1. Is the Tenant's Legal Entity Correct and Financially Reliable?

The first step is to confirm the legal identity of the tenant named in the lease. A business trading under a familiar brand may operate through a separate company or corporate entity, so investors should not assume the trading name is the actual contracting party.

Check the tenant's registered business name, Australian Business Number (ABN), Australian Company Number (ACN), company status and relevant lease documents. Where appropriate, review financial information and available evidence of the tenant's ability to meet rental commitments.

Important checks:

Confirm the tenant's full legal name.
Verify company details through ASIC.
Check ABN information through the Australian Business Register.
Review any parent company or director guarantees.
Request suitable financial information where available.

A tenant with a strong trading presence may still have a financially weak contracting entity. Confirming the correct entity helps investors assess the reliability of the rental arrangement.

2. Are There Any Outstanding Rental Arrears?

Rental arrears can affect the actual income received from a commercial property. Investors should verify that the rent shown in the sales documents matches the amounts paid by the tenant.

Request a rent ledger covering an appropriate period, preferably the previous 12 months or longer where available. Compare the ledger against bank statements, invoices and any outstanding notices.

Document	What it helps verify
Rent ledger	Payment dates and outstanding balances
Bank statements	Actual rental receipts
Rental invoices	Amounts charged to the tenant
Arrears notices	Previous payment issues
Lease agreement	Contractual rental obligations

Also check for rent concessions, disputed invoices, unpaid outgoings and informal payment arrangements.

PRO TIP: Do not calculate investment yield using the advertised annual rent alone. Use verified rental receipts and investigate any outstanding amounts before finalising your financial assessment.

3. How Much Time Is Left on the Commercial Property Lease?

The remaining lease term indicates how long the existing tenant is contractually entitled to occupy the property, subject to the lease conditions.

A property with several years remaining on its lease may offer greater income continuity than one approaching expiry. However, lease length alone does not guarantee tenant retention or future rental payments.

Investors should check:

Original lease commencement date.
Current lease expiry date.
Remaining lease duration.
Any early termination rights.
Upcoming rent review dates.
Existing disputes or breaches.

For example, a commercial property has an annual rental income of $120,000 and only eight months remaining on the current lease. The investor should assess the possibility of vacancy, reletting costs and potential changes in market rent before relying on that income for long term investment calculations.

4. What Renewal Options and Termination Rights Are Included?

Renewal options give tenants contractual rights to extend their occupancy for additional periods, subject to the lease conditions. These options can affect the property's future income, occupancy and ability to negotiate new rental arrangements.

Check the notice period, option exercise date, extension duration and conditions attached to each renewal option. Missing an important notice deadline can change the parties' rights under the lease.

Also review early termination clauses, break rights and any conditions that allow the tenant or landlord to end the agreement.

For example, a tenant may have an option to renew for another five years. The investor should understand how the renewal rent will be calculated and when the tenant must formally exercise that right.

An Australian commercial property solicitor should review these clauses and explain their legal effect before the acquisition is completed.

5. Are the Rental Reviews and Increase Clauses Clearly Defined?

Rental review clauses determine how the rent changes during the lease period. They can influence the property's future income and its estimated investment value.

Common commercial lease review methods include:

Review method	How it works
Fixed percentage increase	Rent increases by an agreed percentage
Consumer Price Index (CPI)	Rent changes according to the specified CPI measure
Market rent review	Rent is assessed against relevant market evidence
Fixed dollar increase	Rent rises by a specified amount

For example, a property generating $100,000 in annual rent with a contractual 3% annual increase would generate $103,000 in the following year, assuming the clause operates as expected.

Investors should also check for review caps, floors, timing restrictions and clauses that limit rent reductions. The wording of each provision matters, so legal interpretation should be obtained from a solicitor.

6. Have Rental Incentives Reduced the Actual Income?

Commercial landlords sometimes offer incentives to attract tenants or secure longer lease commitments. These incentives can make the advertised rent appear higher than the actual income received during the lease period.

Common examples include rent free periods, fit out contributions, cash incentives and reduced initial rental payments.

Consider a five year lease with annual rent of $100,000 and six months rent free at commencement. The face rental value is $500,000 across five years, but the landlord receives only $450,000 before other expenses if the incentive applies at the beginning.

Ask the seller to provide:

Original lease and incentive agreements.
Records of rent free periods.
Fit out contribution details.
Leasing commission records where relevant.
Any side agreements or rental concessions.

Investors should calculate the effective rental income rather than relying on the headline rent stated in the property advertisement.

7. Who Pays the Commercial Property Outgoings?

Commercial property outgoings are the expenses associated with owning and operating the property. The lease should explain which costs are payable by the landlord and which can be recovered from the tenant.

Common outgoings include council rates, water charges, insurance, land tax where applicable, strata levies and property management costs.

The exact recovery arrangements depend on the lease and applicable legislation.

For example, a property generates $120,000 in annual rent, but the landlord pays $20,000 in unrecovered expenses. The net income before other relevant adjustments is $100,000.

Investors should examine the outgoing schedules, invoices, reconciliation statements and any disputes involving the tenant.

Important: Do not assume every expense can automatically be passed on to a commercial tenant. Certain lease types and state or territory laws impose restrictions. Ask a solicitor and tax adviser to review the applicable arrangements.

8. Are Maintenance and Repair Responsibilities Clearly Defined?

Maintenance obligations can create unexpected expenses after a commercial property purchase. The lease should identify the responsibilities of the landlord and tenant for repairs, servicing, replacements and building improvements.

Pay particular attention to:

Roof and structural maintenance.
Air conditioning and ventilation systems.
Electrical and plumbing installations.
Fire safety equipment.
Lifts and shared facilities.
Building compliance and essential safety measures.
Existing repair notices and outstanding works.

For example, a retail property may have an established tenant and consistent rental income, but an ageing air conditioning system could require significant expenditure shortly after settlement.

A building inspection and relevant specialist reports can help identify these issues. Investors should also check if any maintenance obligations have been deferred or disputed.

The lease wording and applicable state legislation should be reviewed by an experienced commercial property solicitor.

9. Does the Permitted Use Allow the Tenant to Operate Legally?

The permitted use clause identifies the business activities the tenant can conduct under the lease. Investors should confirm that the existing business use is consistent with the property's planning controls, development approvals and other relevant requirements.

A tenant operating outside the permitted use or without required approvals can create compliance and financial risks.

Also review assignment and subleasing clauses. These provisions determine the circumstances in which a tenant may transfer its lease or allow another business to occupy the premises.

Important checks include:

Permitted business activities.
Relevant council planning approvals.
Development consent and occupancy requirements where applicable.
Restrictions on hazardous or specialised activities.
Landlord consent requirements for assignments.
Subleasing conditions.
Change of control provisions where relevant.

For example, an industrial property may currently generate rent from a manufacturing tenant. A future change in tenant or business activity could require additional approvals, building modifications or landlord consent.

Investors should confirm the property's approved use with the relevant local council and obtain legal advice before relying on the existing tenancy arrangements.

What Documents Should Buyers Request During Commercial Lease Due Diligence?

Having the right documents available makes it easier to verify rental income and identify contractual obligations before settlement.

Document	Purpose
Signed lease agreement	Confirms the contractual terms
Lease variations	Identifies changes made after signing
Tenant rent ledger	Verifies payment history
Bank rental records	Supports actual income figures
Outgoings statements	Shows property expense arrangements
Incentive agreements	Identifies rent concessions
Tenant details	Confirms the contracting entity
Maintenance records	Reveals outstanding repair issues
Compliance documents	Supports permitted use and property compliance
Assignment and sublease documents	Identifies changes in occupancy arrangements

The documents should be checked against the contract of sale and the vendor's tenancy schedule. Any missing information, inconsistent figures or undisclosed agreements should be investigated before proceeding.

Frequently Asked Questions

1. What is commercial property lease due diligence?

Commercial property lease due diligence is the process of reviewing tenant details, lease agreements, rental payments, renewal rights, incentives, outgoings and maintenance responsibilities before purchasing a leased commercial property. It helps investors identify financial and contractual risks that may affect investment performance.

2. Can an investor purchase a commercial property with a tenant in arrears?

Yes, a commercial property with outstanding rental arrears may still be purchased. However, investors should establish the amount owed, the reason for non-payment and the contractual arrangements for recovering the debt. The purchase contract should clearly address responsibility for outstanding rent and related claims.

3. What happens if a commercial tenant does not renew the lease?

If a tenant does not exercise an available renewal option, the lease may expire according to its terms. The owner may need to find another tenant, negotiate a new agreement or hold the property vacant. Investors should account for potential vacancy periods, leasing costs and reduced rental income.

4. Should a solicitor review a commercial property lease before purchase?

Yes. An experienced Australian commercial property solicitor should review the lease, variations, guarantees, assignment clauses, outgoings and termination provisions. Legal advice helps investors understand contractual rights and obligations before completing the acquisition.

5. Do commercial property owners have to pay for building repairs?

Responsibility depends on the lease, the nature of the repair and applicable legislation. Some costs may be recoverable from tenants, while structural repairs and other obligations may remain with the landlord. Buyers should review the lease and obtain legal advice before calculating future ownership expenses.
