The financing structure lenders expect for petrol station purchases
Most lenders treat petrol stations as specialised commercial property requiring separate funding lines for real estate, fuel inventory, and working capital.
A petrol station purchase typically involves three components. The property itself, including the land, building, and fixed equipment such as underground storage tanks and pumps. The fuel stock on hand, which can represent $40,000 to $120,000 depending on tank capacity and throughput. And working capital to cover supplier payment terms, which often run seven to fourteen days behind sales.
Consider a scenario where a buyer is acquiring a freehold service station in regional Queensland. The property component is $1.2 million. Fuel stock at settlement is $65,000. The buyer needs another $80,000 for initial working capital to maintain supplier terms while cash flow builds. A single commercial property loan won't cover all three. The lender will typically finance up to 70% of the property value as secured debt against the real estate. The fuel stock and working capital require either additional equity or a separate debtor finance facility secured against future receivables.
Lenders distinguish between franchise-operated sites and independent operations. Franchise sites under major fuel brands often qualify for slightly higher loan-to-value ratios because the brand relationship provides income stability and resale value. Independent sites face stricter criteria and may require demonstrated fuel industry experience from the borrower or key staff.
Why fuel stock and environmental compliance affect your loan amount
Fuel stock is excluded from property valuations and funded separately because it depletes and replenishes constantly.
When a lender commissions a commercial property valuation for a petrol station, the valuer assesses the land, buildings, and fixed improvements. Fuel in the tanks is treated as trading stock, not real estate. This means a $1.4 million purchase might be valued at $1.2 million for lending purposes, with the difference representing stock on hand at settlement.
Environmental compliance adds another layer. Lenders require a Phase 1 environmental site assessment before approving finance. If contamination is identified or suspected, a Phase 2 assessment follows. Any remediation liability reduces the amount a lender will advance or triggers a requirement for the seller to remediate before settlement. Sites with older single-walled tanks or incomplete upgrade records face additional scrutiny. Some lenders will decline the application outright if environmental risk is unquantified.
In a scenario where contamination is flagged during due diligence, the loan structure changes. The buyer may need to hold back funds in escrow to cover remediation, funded through equity rather than debt. Alternatively, the purchase price is renegotiated to reflect the liability. Either way, the loan amount decreases, and the deposit requirement increases.
The income verification lenders require for fuel retail businesses
Lenders assess serviceability using net profit after fuel margin, convenience store contribution, and any tenancy income from co-located businesses.
Fuel margin is the difference between the wholesale cost and the retail price per litre, minus credit card fees and shrinkage. This margin is often thin, between two and six cents per litre depending on volume and brand. A site turning over three million litres annually at a four-cent margin generates $120,000 in fuel gross profit. The convenience store or attached food outlet usually contributes more to net profit than fuel sales. Lenders want to see at least two years of trading history showing consistent margins and foot traffic.
If the petrol station includes a tenant, such as a mechanic or car wash operator, rental income is included in serviceability. However, lenders apply a vacancy factor, typically 10%, to account for turnover risk.
Consider a buyer acquiring a site with $420,000 in net profit before interest and tax. Fuel margin contributes $140,000. Convenience store adds $210,000. Rent from a tyre shop contributes $70,000. The lender will assess serviceability using $399,000 after applying a vacancy factor to the rental component. Debt service coverage needs to exceed 1.25 times, meaning annual loan repayments cannot exceed roughly $319,000. At a variable interest rate, that supports a loan amount of around $2.4 million depending on the term.
How franchise agreements and supplier terms shape your borrowing capacity
Franchise agreements often include volume commitments and rebate structures that lenders treat as contingent liabilities.
If you are buying a franchise site, the fuel supply agreement will specify minimum monthly volume targets. Miss the target, and rebates or marketing support may be withdrawn. Lenders review these agreements to understand your exposure. A franchise agreement requiring 200,000 litres per month when the site historically averages 180,000 litres creates a serviceability risk. The lender may reduce the approved loan amount or require additional working capital reserves.
Supplier payment terms also affect cashflow. Most fuel suppliers operate on a seven-day account. You take delivery, sell the fuel over three to five days, and pay the supplier before the next delivery. If your sales cycle stretches or payment processing delays occur, you will need working capital to cover the gap. Lenders assess this as part of the overall funding structure and may require a cashflow solutions facility or debtor finance line to bridge the timing difference.
Structuring the deposit and settlement funds for a petrol station purchase
Most lenders require a 30% deposit for petrol stations, funded entirely from genuine savings or existing unencumbered assets.
Gifts and borrowed deposits are rarely accepted for fuel retail purchases. The lender views the deposit as evidence that the borrower has the financial discipline to manage a cash-intensive operation with tight margins. If the purchase price is $1.5 million, you will need at least $450,000 in verified equity. That figure does not include settlement costs, which add another $40,000 to $60,000 for legal fees, valuation, environmental assessment, and stamp duty.
If you are refinancing an existing commercial property to fund the deposit, the lender financing the petrol station will assess your overall debt position. Total exposure across both properties cannot exceed serviceability limits. Some buyers use business loans or asset finance facilities to fund stock and working capital separately, keeping the commercial loan strictly for property acquisition.
When to use debtor finance alongside your commercial property loan
Debtor finance lets you draw funds against fuel sales before supplier payments are due, smoothing out the cashflow gap that most new petrol station owners underestimate.
Fuel sales generate receivables from credit card processors, fleet card companies, and account customers. Payment processing can take two to three days. Fleet accounts may run on 14-day terms. Meanwhile, your supplier wants payment in seven days. Debtor finance advances you up to 80% of outstanding receivables immediately, with the balance paid once the customer settles.
This structure works separately from your commercial property loan. The property loan funds the real estate. The debtor finance facility funds working capital. The two do not overlap. Some lenders offer both under a single approval, while others require you to arrange debtor finance through a specialist provider.
What happens if environmental issues emerge after settlement
If contamination is discovered after settlement, you are responsible for remediation, but most lenders will not advance additional funds against a contaminated site.
Phase 1 and Phase 2 environmental assessments are completed before settlement, but older contamination or unreported spills can surface later. If a leak is detected from an underground tank or contamination migrates from a neighbouring site, remediation costs fall to the owner. These costs can range from $50,000 for minor soil treatment to $500,000 or more for groundwater contamination.
Lenders will not refinance or increase the loan amount on a contaminated site until remediation is complete and a site audit statement is issued. You will need to fund remediation from working capital, external equity, or personal resources. This is one reason why buyers with limited reserves should avoid sites with aging infrastructure or incomplete environmental records.

Frequently Asked Questions
How much deposit do I need to buy a petrol station?
Most lenders require a 30% deposit for petrol station purchases, funded from genuine savings or unencumbered assets. Borrowed deposits and gifts are rarely accepted because lenders view the deposit as evidence of financial discipline.
Is fuel stock included in the commercial property loan?
No, fuel stock is excluded from property valuations and must be funded separately. Lenders treat fuel as trading stock that depletes and replenishes, not as part of the real estate value.
What environmental checks do lenders require for petrol station finance?
Lenders require a Phase 1 environmental site assessment, and a Phase 2 assessment if contamination is suspected. Any identified contamination must be remediated or the loan amount will be reduced to account for the liability.
How do lenders assess income from a petrol station?
Lenders assess net profit from fuel margin, convenience store sales, and any rental income from tenants. They typically require at least two years of trading history and apply a vacancy factor to rental income.
Can I use debtor finance to cover fuel supplier payment terms?
Yes, debtor finance advances up to 80% of outstanding receivables from fuel sales, helping cover the gap between sales and supplier payment deadlines. This facility operates separately from your commercial property loan.
