Commercial loan structuring determines how much you can borrow, what you pay each month, and how quickly you can respond when opportunity or challenge arrives.
A medical practice buying consulting rooms on Burwood Road, a manufacturing business acquiring warehouse space near the Glenferrie corridor, or a retail operator securing a mixed-use property in Hawthorn Village will face different cash flow patterns, tax positions, and future plans. The way the loan is structured should reflect those differences, not follow a standard format.
What Commercial Loan Structuring Actually Involves
Commercial loan structuring is the process of organising how debt is arranged across facilities, repayment types, security, and terms to match the borrower's income, goals, and risk profile. It includes deciding whether to split between variable and fixed interest rates, whether to use interest-only or principal and interest repayments, how to allocate security across multiple properties, and whether to include features like redraw or offset.
Consider a buyer acquiring an office building in Hawthorn with a mix of long-term tenants and short-term leases. Structuring the loan with a split between fixed and variable interest rates gives protection against rate rises while retaining the flexibility to pay down debt if rental income exceeds forecast. Adding a revolving line of credit against undrawn equity allows the borrower to cover capital expenditure or fit-outs without refinancing the entire facility.
How Loan Structure Affects Borrowing Capacity
The way a commercial property loan is structured directly impacts how much a lender will approve. Lenders assess serviceability based on net rental income and the borrower's capacity to meet repayments under stress conditions. Choosing principal and interest repayments reduces the loan amount you can borrow compared to interest-only, because monthly repayments are higher. Choosing interest-only preserves borrowing capacity but requires a clear exit strategy at the end of the interest-only period.
For a business owner in Hawthorn expanding into a second location, structuring the loan to include a progressive drawdown rather than a lump sum at settlement aligns funding with the fit-out schedule and reduces interest costs during construction. This approach also improves serviceability during the application, as the lender assesses repayments based on the drawn amount rather than the full facility.
Interest-Only vs Principal and Interest Repayments
Interest-only repayments mean you pay only the interest charged each month, with no reduction to the loan amount. Principal and interest repayments include both interest and a portion of the loan balance, so the debt reduces over time. Interest-only periods on commercial property finance typically run for one to five years, after which the loan reverts to principal and interest unless renegotiated.
Interest-only repayments suit investors prioritising cash flow or planning to sell or refinance within the interest-only period. Principal and interest repayments suit borrowers holding property long-term or seeking to build equity steadily. The decision should account for rental income stability, tax treatment, and whether the borrower has other uses for the cash flow preserved by interest-only repayments.
Fixed vs Variable Interest Rate Structures
A variable interest rate moves in line with market conditions and the lender's pricing. A fixed interest rate locks in a rate for a set period, typically one to five years. Most commercial finance structures allow a split between fixed and variable, giving certainty on part of the debt while retaining flexibility on the rest.
In our experience, businesses operating on tight margins or with predictable revenue prefer a higher fixed component to stabilise repayments. Investors with surplus cash flow or plans to pay down debt quickly prefer a higher variable component to avoid break costs and retain access to redraw or offset features. A 50/50 split is common but not always appropriate. The right balance depends on the borrower's risk tolerance, interest rate outlook, and whether they need the flexibility to make lump sum repayments.
Security and Cross-Collateralisation Considerations
Security refers to the assets a lender can claim if the loan defaults. In commercial lending, security can include the property being purchased, other commercial or residential properties, business assets, or personal guarantees. Cross-collateralisation occurs when multiple properties are used as security for a single loan or linked loan facilities.
A business owner in Hawthorn purchasing an industrial property near Auburn Road might use their existing residential property as additional security to reduce the commercial LVR and access lower interest rates. While this increases borrowing capacity, it also means the lender holds security over both properties. If the business encounters difficulty, both assets are at risk. Structuring loans with separate security where possible preserves flexibility and limits exposure, particularly when the borrower plans to sell one property or refinance in future.
Facility Limits and Revolving Credit Options
A facility limit is the maximum amount a lender will make available under the loan agreement. A revolving line of credit allows the borrower to draw, repay, and redraw funds up to the facility limit without reapplying, similar to a business overdraft secured against property. This structure suits businesses with variable capital requirements or investors managing multiple properties.
For a retail operator acquiring a strata title commercial property in Hawthorn, a revolving credit facility provides access to funds for fit-outs, stock purchases, or unplanned repairs without disrupting the primary loan. The borrower pays interest only on the drawn amount, and repayments reduce the outstanding balance, making funds available again. Lenders typically charge a higher interest rate on revolving facilities compared to standard term loans, so the structure works when flexibility justifies the additional cost.
Structuring for Refinance or Development
Loan structure should anticipate future needs, not just current circumstances. A borrower planning to refinance within two years to access equity or secure lower rates should avoid long fixed rate periods or loans with high exit fees. A borrower planning commercial development or subdivision should structure the acquisition loan to allow for future mezzanine financing or construction facilities without requiring full discharge.
In a scenario like this, a buyer acquires a warehouse in Hawthorn with council approval for office conversion. Structuring the acquisition loan with a lower fixed component and minimal exit penalties allows the borrower to refinance into a commercial construction loan within 12 months without incurring break costs. The initial loan includes a valuation clause permitting revaluation after development approval, which improves the LVR and reduces the deposit required for the construction phase.
Tax and Cash Flow Implications
Interest on a commercial property loan is typically tax-deductible when the property generates assessable income. Loan structure affects the amount of interest paid each year and the timing of deductions. Interest-only repayments maximise deductions in the early years, which can suit borrowers with high taxable income. Principal and interest repayments reduce interest paid over time, lowering deductions but building equity faster.
Cash flow management often determines structure more than tax. A business with seasonal revenue might structure repayments to align with income cycles, or include a redraw facility to smooth cash flow between high and low periods. A property investor in Hawthorn holding multiple commercial assets might consolidate debt under a single facility with flexible repayment options to simplify administration and reduce costs.
When to Review Loan Structure
Loan structure should be reviewed when circumstances change, not only at refinance. Triggers include interest rate movements, changes in rental income, acquisition or sale of other properties, business expansion, or shifts in tax position. A structure that worked at purchase may no longer suit the borrower's current situation.
We regularly see businesses hold onto loan structures long after they stop serving their purpose, often because they assume restructuring requires full refinance. Many lenders allow variations to loan terms, repayment types, or facility limits without discharging the loan, particularly when the borrower's equity position has improved. Reviewing structure annually ensures the loan continues to support the borrower's goals rather than constrain them.

Frequently Asked Questions
What is commercial loan structuring?
Commercial loan structuring is the process of organising how debt is arranged across facilities, repayment types, security, and terms to match the borrower's income, goals, and risk profile. It includes decisions on interest rate types, repayment structures, security arrangements, and facility features like redraw or revolving credit.
Should I choose interest-only or principal and interest repayments?
Interest-only repayments suit investors prioritising cash flow or planning to sell or refinance within the interest-only period, typically one to five years. Principal and interest repayments suit borrowers holding property long-term or seeking to build equity steadily.
What is cross-collateralisation in commercial lending?
Cross-collateralisation occurs when multiple properties are used as security for a single loan or linked loan facilities. While this can increase borrowing capacity and reduce interest rates, it means the lender holds security over all properties, increasing risk if repayments become difficult.
How does loan structure affect borrowing capacity?
Loan structure directly impacts how much a lender will approve based on serviceability. Interest-only repayments preserve borrowing capacity compared to principal and interest, which have higher monthly repayments. Progressive drawdowns and facility types also influence the amount lenders will approve.
When should I review my commercial loan structure?
Review loan structure when circumstances change, including interest rate movements, changes in rental income, acquisition or sale of properties, business expansion, or shifts in tax position. Many lenders allow variations to loan terms without full refinance, particularly when equity has improved.
