Purchasing commercial property checklist

 Why Every Buyer Needs a Purchasing Commercial Property Checklist

This is the complete Australian buyer's guide for 2026. A comprehensive purchasing commercial property checklist could save you hundreds of thousands of dollars—and years of frustration. Whether you're acquiring premises for your own business, building an investment portfolio, or planning a strategic transition toward retirement, the difference between a successful acquisition and a costly mistake often comes down to thorough preparation.

After 40 years in commercial real estate—including working with hundreds of business owners navigating property purchases—I've seen how the right due diligence protects buyers from hidden pitfalls, while inadequate preparation leads to legal disputes, unexpected costs, and missed opportunities.

This purchasing commercial property checklist isn't just a list of boxes to tick. It's a comprehensive framework designed to help you make informed decisions, protect your interests, and position your acquisition for long-term success.

Your Financial Position: What Can You Actually Afford?

Before you start viewing properties, you need absolute clarity on your financial capacity. This isn't just about what the bank will lend you—it's about what makes sense for your circumstances and goals. This section of your purchasing commercial property checklist addresses the financial foundations.

Cash and Borrowing Capacity

Start by determining your available deposit. Commercial property loans typically require a minimum 20–30% deposit, though some lenders may require more depending on the property type and your financial profile.

Also note that banks tend to charge higher interest rates on lower deposits, so this should be factored into your calculations.

Speak with your bank or a commercial finance broker about your borrowing limits. Be realistic—lending policies have tightened considerably in recent years, and what you could borrow five years ago may not reflect today's reality.

Stress-Testing Your Serviceability

Interest rates fluctuate. Tenants leave. Unexpected maintenance costs arise. Can you service the loan if interest rates increase by 2–3%? What happens if the property sits vacant for six months?

Consider these scenarios seriously. Many property investors who purchased during low-interest periods have faced significant pressure as rates normalised. Building a financial buffer isn't pessimism—it's prudent planning. Is the area genuinely improving, or is it declining? Is there a change in demographics?

Although it's unlikely to happen again, I recall the high interest rates of the late 1980s. We had just purchased our first home at 15.5% interest, which was a record high at the time. I recall the bank manager telling me that rates would never go higher than this. Soon afterwards, interest rates rose to 17.5%. I also recall negotiating loans for my commercial clients during the same period. At that time, commercial property interest rates were sitting in the low 20s.

Understanding Total Acquisition Costs

The purchase price is just the beginning. Factor in stamp duty (which varies by state and property value), legal fees, building and pest inspections, valuations, loan establishment fees, and any immediate repairs or fit-out costs. In NSW alone, stamp duty on a $2 million commercial property can exceed $95,000.

Location Analysis for Commercial Property Purchase

Everyone knows location matters. But for commercial property, understanding *why* it matters—and how locations change over time—separates successful investors from those who buy at the wrong time or in the wrong place.

Although the common property term has always been "location, location, location," I've seen many cases where great locations have ended up being average locations, and poor locations have become good locations. This is where good homework comes in. Look at the area and see what's happening. Even a look at the local council website may reveal many problems and opportunities.

Current Demand and Tenant Pool

For investment properties, you need confidence in ongoing tenant demand. Research vacancy rates in the area for your property type. What businesses are operating nearby? Is there a diverse economic base, or does the area depend on a single employer or industry?

This is especially true in small regional areas and country towns that rely on one or two major employers. It may be a good idea to do some research on those employers. They may be public companies. Are they performing well? Are they struggling? Check their stock prices. Are they expanding in other areas? Are they talking about consolidating? All these factors should be considered.

When I visit a new area, I like to have a good walk around, see what's going on, and even talk to some locals. They can all be sources of valuable information.

I recall a situation where a pub was built next to a coal mine. Sounds obvious—many well-paid miners buying lunch, having dinner, and enjoying a few beers after work. Sounds like a good situation. The only problem was that the mine shut down two months later, leaving the pub high and dry.

If you're purchasing premises for your own business, consider customer access, parking availability, proximity to suppliers, and whether the location supports your operational needs. Can you subdivide and reduce your area and lease part of it to someone else if business slows down? On the other hand, that same flexibility will allow you to expand if you need to in the future.

Future Infrastructure and Zoning Changes

Local councils publish strategic plans outlining future development, infrastructure projects, and potential zoning changes. A new motorway bypass could devastate a roadside retail property—or create opportunity in a newly accessible area.

Research planned infrastructure projects, proposed zoning amendments, and demographic trends. An area shifting toward younger families might support childcare and education facilities. An ageing population could favour medical and aged-care uses.

Economic Vulnerability Assessment

What happens to this location if a major employer closes? If a new shopping centre opens nearby? If flood mapping changes affect insurance costs? Consider the economic resilience of the area, not just its current state.

Commercial Property Types: Matching Investment to Strategy

The commercial property market encompasses diverse asset classes, each with distinct risk-return profiles, management requirements, and market dynamics. Understanding these categories is essential to any purchasing commercial property checklist.

Retail Property

Retail properties range from strip shops to neighbourhood shopping centres. Returns can be attractive, but retail has faced significant disruption from e-commerce. Consider tenant quality, lease structures, and whether the retail mix serves genuine local needs or depends on discretionary spending.

Industrial and Warehouse

Industrial property has performed strongly, driven by logistics and e-commerce fulfilment. These properties often feature longer leases and lower management intensity than retail. However, industrial land values vary significantly based on access to transport corridors and workforce availability.

Commercial Offices

Office property faces ongoing uncertainty as hybrid work patterns reshape demand. Premium CBD assets remain sought-after, but secondary office stock may face structural vacancy challenges. Consider the building's amenity, parking ratios, and flexibility for different uses.

Specialised Properties

Hospitality venues, medical facilities, childcare centres, and other specialised properties can offer higher returns but require specific expertise to evaluate. The tenant's operational success directly affects your investment—a failing restaurant doesn't pay rent.

It may be a good idea to work with someone who understands both the property and business side of the deal to help you assess the viability of potential tenants. I have found over the years that less experienced tenants tend to offer higher rents in order to secure premises. They may succeed, but it's a risk you must consider before signing.

Property Adaptability and Future Potential

Smart commercial property buyers think beyond current use. What could this property become?

When I look at a property, I consider what happens if things don't go perfectly: what are the alternatives, and can it be changed to another use? I call this buying a "utility property" because things change all the time. COVID was a good example. Retail took a big hit. Industrial improved out of sight and continues to thrive alongside online marketing. Then we look at what happened to the office market during COVID. It took a big hit and is recovering now, but will it recover enough to reach the heights of what it was like before COVID? Be aware of what's going on.

Redevelopment and Expansion Potential

Can the property be extended, subdivided, or redeveloped? Is there surplus land that could accommodate additional buildings? Understanding the site's development potential helps you assess its true value—and plan for capital growth.

I have found that zoning upgrades tend to happen in waves. If one area is upgraded to allow for higher commercial use, there is a possibility that nearby areas could be rezoned in the near future. So if you had a choice of two properties:

1. One with no major zoning changes in the surrounding area
2. Another one with zoning changes happening nearby

If the return and all other factors were similar, it may be worth going for the one with greater surrounding potential.

Alternative Use Possibilities

If the current use becomes obsolete, what else could the property accommodate? Industrial buildings have converted to residential, offices to boarding houses, motels to aged care. A property with multiple potential uses offers greater flexibility and risk mitigation.

Don't only look at the property as it is at the moment. Think about the possibility of things going wrong. If there was a slowdown of demand for the type of tenant that property was suited for, can it be converted to something else?

Over the years, we have converted many properties to other uses. Examples include:

- Motels to backpackers hostels
- Offices to boarding houses
- Industrial properties to residential
- Properties with retail mix reconfigurations
- Land subdivisions
- Residential properties to childcare centres, boarding houses, or over 55's residential.

Zoning and Development Pathways

Research the current zoning and what uses it permits. Some properties may have development applications already approved or in progress—adding value you should verify. Others may have restrictions that limit future options.

Due Diligence Checklist for Commercial Property Purchase

Thorough due diligence protects you from nasty surprises. Cutting corners here to "save money" almost always costs more in the long run. This is arguably the most critical section of any purchasing commercial property checklist.

Building and Structural Inspection

Engage a qualified building inspector experienced with commercial properties. They should assess structural integrity, roof condition, electrical and plumbing systems, fire safety compliance, accessibility requirements, and identify any defects requiring rectification.

For older buildings, pay particular attention to asbestos, outdated electrical systems, and compliance with current building codes.

Pest and Termite Inspection

Termite damage can be concealed and catastrophic. A thorough pest inspection is essential, particularly for older timber-framed buildings or properties in termite-prone areas.

Take note of any areas where the inspector has indicated they could not obtain access.

Verification of Current Approvals

This is critical—and frequently overlooked. Many property owners assume their tenants have proper development approval. They often don't.

I've seen businesses operating "illegally" for 20+ years without proper approval. When challenged, councils don't care how long the use has continued—they care whether it was ever approved.

I have seen approved boarding houses actively operating as backpackers for years. I've seen approved wholesalers and manufacturers selling retail, and several other instances of businesses operating outside their approval.

Request copies of all development approvals from the vendor. Verify them with the local council. Ensure the current use—and any advertised future use—is actually permitted.

Environmental Due Diligence for Commercial Property

Environmental issues can transform a promising investment into an expensive liability. Australian environmental regulations are increasingly stringent, and liability for contamination can follow a property regardless of who caused the problem. Don't assume that current regulations will not change in the future.

Site Contamination Assessment

For any property with industrial history—or neighbouring industrial uses—commission a Phase 1 Environmental Site Assessment. This desktop review examines historical uses, surrounding activities, and identifies potential contamination concerns.

If contamination is suspected, a Phase 2 assessment involves physical sampling and testing. Remediation costs for contaminated sites can run into millions of dollars. Don't assume the vendor's assurances are sufficient.

Most potential buyers are put off by contaminated sites, and on the surface, they should be. No one wants to buy a problem building or property. I suggest that my clients look at it from the other side. For example, look at the absolute highest cost it would take to remediate that site if you needed to do so, and deduct that amount from the sale price. A simple mathematical calculation may uncover a real bargain.

An example of this would be a petrol station. Petrol stations are notorious for contamination. It was a very small site, and I estimated it would be worth about $1.2 million if it did not require any remediation. I did some research to determine what it would cost to remediate the entire site if it were polluted. My estimate came to around $200,000, which at the time was a lot of money.

As the owner was desperate to sell the property, he let it go for $800,000. So if the buyer had to remediate the whole site, he still picked it up for around $200,000 less than market value. To my knowledge, no remediation was required, and since the property allowed further development, the new owner developed it and now has a nice little cash cow.

I don't encourage my clients to actively seek problem buildings unless they really know what they're doing and have the appropriate knowledge and context to assess the situation before buying.

Asbestos Register and Management

Commercial buildings constructed before 1990 likely contain asbestos materials. Request the property's asbestos register and management plan. Understand where asbestos is present, its condition, and any removal or management requirements. Budget accordingly.

Flood and Bushfire Mapping

Climate-related risks are increasingly material to property values and insurability. Check current flood mapping—and proposed updates—through your local council. Review bushfire attack level (BAL) ratings for properties in regional or peri-urban areas.

Properties in high-risk zones may face insurance challenges, lending restrictions, or reduced tenant appeal.

A good example of this was over 10 years ago when I consolidated a large site on the North Coast of NSW, which comprised an existing motel plus two adjoining properties. Combined, they would have been suitable for around 100 residential subdivisions. Around the same time I commenced marketing, there were extensive bushfires in the area, and the council was considering increasing setbacks from the boundary lines, which would severely reduce the number of residential blocks that could be carved out in the future.

Hazardous Materials and Waste

Beyond asbestos, older commercial properties may contain lead paint, PCBs in electrical equipment, underground storage tanks, or other hazardous materials. Identify these issues before purchase—remediation responsibility typically transfers with ownership.

Strata and Body Corporate Checklist

If you're purchasing a unit within a strata complex—whether office suites, retail units, or industrial strata—additional due diligence is essential. Include these items in your purchasing commercial property checklist for strata purchases.

Strata Records Inspection

Request a strata inspection report (Section 184 certificate in NSW, or equivalent in other states). This reveals outstanding levies, special assessments, sinking fund balances, insurance details, and any litigation involving the owners corporation.

Review minutes from recent strata meetings. Are there disputes between owners? Major works planned? Contentious issues that could affect your enjoyment or cost of ownership?

Sinking Fund Adequacy

The sinking fund should be sufficient to cover anticipated capital works. A building with a depleted sinking fund and ageing infrastructure is likely to face significant special levies. Request a sinking fund forecast or capital works plan.

By-Laws and Restrictions

Strata by-laws can restrict signage, operating hours, permitted uses, and alterations. Ensure the by-laws accommodate your intended use—and that you can comply with existing restrictions.

Common Property and Exclusive Use

Understand exactly what you're purchasing. What's part of your lot versus common property? Are there exclusive use rights included? Who maintains shared facilities, and how are costs allocated?

Insurance Requirements for Commercial Property Purchase

Adequate insurance is non-negotiable—but commercial property insurance is more complex than residential coverage. Every purchasing commercial property checklist should include insurance verification.

Building Insurance

For standalone properties, you'll need building insurance covering the structure against fire, storm, and other perils. For strata properties, building insurance is typically arranged by the owners corporation—verify coverage limits are adequate and the policy is current.

A common problem I have found with landlords is that they are always looking for ways to reduce their expenses, which is understandable. However, some make the mistake of under-insuring. For example, the insurable value of your property may be $2 million, but many property owners think they should only insure for $1.5 million. If in this case the $2 million building was insured for $1 million—or 50% of the building cost—and there was a situation requiring a claim, generally they may only be able to claim 50% of the cost of rebuilding. This leaves them vulnerable to increased construction costs and reductions in cash flow.

Public Liability Insurance

Public liability coverage protects against claims from injuries occurring on your property. Minimum coverage of $10–20 million is standard for commercial properties. Your tenants should also maintain their own public liability insurance.

Business Interruption and Loss of Rent

If the building is damaged and tenants can't occupy, loss of rent insurance covers your income during the repair period. This coverage is often overlooked but can be essential for maintaining loan serviceability.

Specialised Coverage Requirements

Certain property types require specialised insurance. Hospitality venues need liquor liability coverage. Properties with environmental risks may require pollution liability coverage. Machinery breakdown coverage may be appropriate for industrial properties with significant plant and equipment.

Insurance Challenges

Some properties face insurance difficulties—flood-prone sites, heritage buildings, or properties with certain uses. Before committing to purchase, verify that appropriate insurance is available at a reasonable cost.

Current Tenancy Analysis

For investment properties, the quality and terms of existing tenancies significantly affect your return and risk profile. Lease analysis is a key component of your purchasing commercial property checklist.

Lease Documentation Review

Obtain and review all current lease documents. Key terms include rental amount, payment frequency, review mechanisms (CPI, market, fixed increases), lease term and renewal options, make-good provisions, and landlord versus tenant maintenance responsibilities.

Rental Market Comparison

Is the current rent consistent with market rates? Above-market rents may indicate a tenant planning to leave at lease expiry. Below-market rents represent potential upside—but also suggest historical management issues.

It may be a good idea to consider providing your tenants with some assistance during adverse economic conditions, especially when rents are falling in surrounding areas. Most tenants will appreciate this and will take it into consideration when it comes to paying a higher rental once economic conditions improve.

I learned this lesson early in my property career. I was working as a property manager looking after around a hundred commercial properties for a Sydney-based company. This was a period of high inflation and high interest rates. My clients were fairly flexible to ideas and supported my philosophy of maintaining market rentals even though rents were falling in the inner city area of Sydney. Whilst most property owners stuck to the rentals they were used to before things changed, our policy of sticking to market rentals and keeping a close ear to the ground on what was happening in the economy ensured we never dropped below 90% occupancy—whilst many buildings in the area remained empty for months, some for years.

The result was obviously continuous cash flow. And when conditions improved, we had the tenants in place and were able to charge higher rents.

Tenant Financial Health

A lease is only as valuable as the tenant's ability to pay. For significant tenancies, request financial information or conduct searches to assess the tenant's business health. Consider the tenant's business model—is it sustainable long-term?

Payment History

Request a statement from the vendor confirming rental payment history. Consistent late payments indicate potential problems. A tenant already in arrears at settlement becomes your problem.

Weighted Average Lease Expiry (WALE)

For properties with multiple tenants, calculate the WALE—the average remaining lease term weighted by rental income. A longer WALE provides income security; a shorter WALE may indicate upcoming vacancy risk or re-leasing costs.

Property Management Considerations

Commercial property isn't truly passive. How you'll manage the property should factor into your purchase decision.

Self-Management vs Professional Management

Managing commercial property requires time, expertise, and availability. Tenant communications, maintenance coordination, lease administration, compliance requirements—are you equipped to handle these responsibilities?

Professional management typically costs 3–7% of gross rent. For many investors, particularly those acquiring property as part of retirement planning, professional management provides valuable peace of mind.

Return on Your Time

If you're still running a business, consider whether managing an investment property represents the best use of your time. The apparent "savings" from self-management may actually cost more than professional fees when you account for the opportunity cost.

Management Transition Planning

If you're purchasing as part of a broader transition strategy—perhaps planning to reduce business involvement over the coming years—factor property management into that planning. Systems and relationships established now will support a smoother transition later.

Buying with Partners or Through Syndicates

Purchasing with others can provide access to larger properties and shared expertise, but also introduces complexity and risk.

Partnership Structures

Options include joint tenancy, tenancy in common, companies, unit trusts, or formal syndicate structures. Each has different implications for decision-making, liability, taxation, and exit flexibility. Get proper legal and accounting advice before committing.

Partnership Agreement Essentials

Document everything. Decision-making processes, capital contribution requirements, distribution policies, dispute resolution mechanisms, and most critically, exit provisions. How does a partner sell their interest? What happens if partners disagree fundamentally?

Due Diligence on Partners

Understand who you're partnering with. What's their financial capacity? Experience? Decision-making style? A partnership that seems attractive initially can become problematic when circumstances or opinions diverge.

Financing Your Commercial Property Purchase

Commercial property finance differs significantly from residential lending. Understanding your options helps you structure the optimal arrangement for your commercial property purchase.

Traditional Bank Finance

Major banks offer commercial property loans, typically at higher rates and lower loan-to-value ratios than residential lending. Expect 60–70% LVR maximums, with lower ratios for specialised or higher-risk properties. Terms typically range from 15–25 years with variable or fixed rate options.

Alternative Financing

Beyond traditional banks, consider credit unions, non-bank lenders, private lenders, and vendor finance options. Each has different criteria, costs, and flexibility. For properties that don't fit standard lending criteria, creative financing may be necessary.

Finance Pre-Approval

Before making offers, obtain finance pre-approval. This confirms your borrowing capacity, strengthens your negotiating position, and enables faster settlement once you find the right property.

Equity Considerations

Understand how your equity position will change post-purchase. Are you over-leveraged? Do you have capacity for future opportunities—or to manage unexpected challenges? Conservative leverage provides flexibility that aggressive borrowing sacrifices.

Building Age and Condition Assessment

Older buildings can offer attractive returns—but require careful assessment of condition and future capital requirements.

Building Systems Review

Beyond structural elements, assess the condition and remaining life of mechanical systems—air conditioning, lifts, fire systems, hydraulic services, and electrical infrastructure. Replacement costs for major systems can be substantial.

Compliance Gap Analysis

Building codes evolve. An older building may not comply with current requirements for fire safety, accessibility, energy efficiency, or other standards. While existing use rights may provide some protection, significant refurbishment typically triggers compliance upgrade requirements.

Capital Expenditure Forecasting

Based on building age and condition, estimate capital expenditure requirements over your intended holding period. Factor these costs into your return calculations—a higher yield becomes less attractive when substantial capital works are imminent.

Heritage and Conservation

Heritage-listed buildings come with additional constraints—and potential opportunities. Understand any heritage overlays, what works require heritage approval, and how heritage status affects adaptability. Some heritage buildings qualify for conservation incentives.

Creating Your Commercial Property Investment Plan

Commercial property investment should be treated as a business, not a casual transaction. A clear plan provides direction and enables better decisions.

Investment Strategy Clarity

What are you trying to achieve? Income generation? Capital growth? Premises for your own business? A legacy asset for future generations? Different objectives lead to different property choices and management approaches.

Timeline and Exit Planning

How long do you intend to hold the property? Under what circumstances would you sell? Having a clear exit strategy—even if you hope never to use it—helps you make better decisions and avoid being forced to sell at the wrong time.

Integration with Broader Plans

How does this property fit within your overall financial position and life plans? For business owners approaching retirement, property acquisitions should integrate with broader transition planning. The property that makes sense at 45 may not be appropriate at 60.

Contingency Planning

What happens if things don't go as planned? Tenant defaults, market downturns, personal health issues, family circumstances—life rarely proceeds exactly as expected. Build flexibility and resilience into your planning.

Working with Professional Advisors

Complex transactions require professional support. Assembling the right team protects your interests and improves outcomes.

Commercial Real Estate Agent

An experienced commercial agent with relevant market knowledge can identify suitable properties, provide market intelligence, and help negotiate favourable terms. For purchasers, buyer's agent services may be valuable—particularly if you're unfamiliar with commercial property or time-constrained.

Commercial Property Solicitor

Commercial property transactions involve complex documentation—contracts, leases, easements, development approvals. A solicitor experienced in commercial property (not just residential conveyancing) protects your legal interests and identifies issues before they become problems.

Accountant and Tax Advisor

Commercial property has significant tax implications—depreciation, GST, land tax, income tax, capital gains tax, and structuring considerations. Get advice before purchasing, not after. The right structure can save substantial money; the wrong structure can cost you.

Finance Broker

A commercial finance broker can access multiple lenders, identify optimal loan structures, and navigate complex applications. Their market knowledge often secures better terms than approaching a single bank directly.
