The easiest way to structure a commercial loan

Structure determines how much you pay and how quickly you can adapt.

Business owners buying commercial property in Wentworthville often focus on the interest rate and the loan amount, then accept whatever structure the lender suggests. But the way a commercial loan is structured controls your repayment flexibility, tax position, and ability to reinvest capital as your business grows. A warehouse owner paying principal and interest on the full loan amount might reduce debt faster, but they also lock up cash flow that could have funded equipment upgrades or a second property. An interest-only period on part of the loan frees up that cash without increasing total interest paid by much, if the structure matches how the business actually generates income.

Consider a buyer purchasing a small retail and office strata unit on Station Street near Wentworthville station. The property costs $850,000, they have a 30% deposit, and they want to borrow $595,000. One lender offers a single loan at a variable interest rate with principal and interest repayments over 25 years. Another broker structures it as a $400,000 principal and interest loan on a 20-year term, with a $195,000 interest-only loan on a five-year term. Monthly repayments start lower in the second structure, the buyer keeps $18,000 more in working capital over the first two years, and at the end of year five they can refinance the interest-only portion or pay it down depending on what the business needs. The purchase price is identical. The interest rate is nearly identical. The outcome is not.

Why loan structure matters more than the rate

Loan structure controls cash flow, tax deductibility, and how easily you can adapt the debt as circumstances change. A lower interest rate on a rigid structure often costs more over time than a slightly higher rate on a loan you can actually use. If you set up principal and interest repayments across the full loan amount from day one, you reduce debt fastest but you also commit the highest monthly amount with no flexibility to pause or redirect that capital. If you split the loan and keep part of it interest-only for a set period, you reduce the monthly commitment and create room to reinvest or absorb a revenue gap without breaching loan terms.

In our experience, buyers who structure a portion of the debt as interest-only for the first three to five years end up with more working capital and better ability to manage uneven income, particularly in the early years after settlement. The total interest paid over the life of the loan increases slightly, but the flexibility to redirect cash into the business often produces a higher return than the cost of that extra interest. Fixed interest rate terms can also be layered into the structure, locking in repayments on part of the loan while leaving the rest variable. This limits exposure to rate rises without removing all flexibility.

Principal and interest versus interest-only

Principal and interest repayments reduce the loan balance with every payment, building equity and lowering total interest over time. Interest-only repayments keep the loan balance unchanged, reduce the monthly amount due, and preserve cash for other purposes. Neither option is better in isolation. The right choice depends on whether the business benefits more from debt reduction or from liquidity in the short term.

A Wentworthville business buying an industrial property on Railway Parade to consolidate warehouse and office space might set the loan as principal and interest if cash flow is strong and the intention is to own the property outright within 15 years. The same buyer might switch part of the loan to interest-only if they plan to expand into a second location within three years and need to preserve capital for that deposit. The property and the loan amount remain the same, but the structure changes based on what the business is trying to achieve.

Interest-only terms typically run for one to five years, after which the loan reverts to principal and interest unless you refinance or restructure. This reversion increases monthly repayments, so the structure should account for that step-up in advance. If cash flow will be stronger in three years, an interest-only term makes sense. If not, committing to principal and interest from the start avoids a future repayment increase you cannot afford.

Splitting the loan across multiple facilities

A split structure divides the total loan amount into two or more separate facilities, each with its own term, rate type, and repayment method. One portion might be fixed for three years on principal and interest repayments, while another portion remains variable and interest-only. This approach lets you lock in certainty on part of the debt while keeping flexibility on the rest.

Consider a buyer purchasing a small office building in Wentworthville for owner-occupation and leasing the upper level to a tenant. They borrow $700,000 secured against the property. A split structure might allocate $450,000 to a fixed rate loan on principal and interest repayments, matching the portion of the property the business occupies and intends to hold long-term. The remaining $250,000 sits on a variable rate interest-only loan, matching the tenanted portion and preserving the option to pay down or refinance that portion if the tenant vacates or if the owner wants to sell and upgrade in a few years. The structure reflects how the property is used and how the income is generated, rather than treating the entire loan as a single commitment.

Splitting also reduces refinancing cost and complexity. If rates drop or circumstances change, you can refinance one portion without touching the other. If you want to pay down part of the debt early, you can target the interest-only portion without breaking a fixed rate term and triggering exit costs.

Using a revolving line of credit within the structure

A revolving line of credit functions like a flexible loan limit you can draw on, repay, and redraw as needed, similar to a redraw facility but with more control and often a separate account. It works for buyers who need occasional access to capital without applying for a new loan each time. The line of credit sits alongside the main loan as part of the overall structure, secured by the same commercial property, but with its own limit and terms.

We regularly see this used by Wentworthville business owners who buy commercial property and need ongoing access to funds for fit-outs, equipment, or covering gaps between tenant lease renewals. A $50,000 revolving line of credit attached to a $600,000 commercial property loan gives the buyer access to working capital without needing to apply for separate equipment finance or short-term funding. Interest is only charged on the amount drawn, and the facility can be repaid and reused within the approved limit. It adds cost if used frequently, but it removes the need to over-borrow at settlement or apply for new finance every time the business needs capital.

Secured versus unsecured portions of the loan

Most commercial property loans are fully secured against the property being purchased, but some structures include an unsecured portion to cover costs the lender will not include in the secured loan, such as fit-out, working capital top-up, or settlement costs that exceed the borrowing limit. The unsecured portion carries a higher interest rate and shorter term, but it allows the buyer to fund the full transaction without needing separate finance or paying those costs from savings.

An unsecured commercial loan component makes sense when the property valuation or loan-to-value ratio leaves a funding gap and the buyer has strong cash flow to service the higher repayments. It is less useful if cash flow is already stretched, because the higher rate and shorter term increase the monthly commitment significantly. In most cases, contributing more deposit or selecting a different property is a more sustainable option than adding unsecured debt to the structure.

How loan structure affects tax and deductibility

Interest paid on a loan used to purchase income-producing commercial property is typically tax-deductible. The structure of the loan does not change whether interest is deductible, but it does affect how much interest you pay and when. Principal and interest repayments reduce the loan balance, which reduces the total interest paid over time but also reduces the annual deduction. Interest-only repayments keep the loan balance and the annual interest charge higher, which increases the deduction but costs more in total interest unless you invest the saved cash flow at a return higher than the loan rate.

If the property is used partly for business and partly leased to tenants, some buyers split the loan to match that usage and keep deductibility clear. The portion matching the leased space sits on its own facility, and all interest on that portion is deductible. The portion matching owner-occupied space may or may not be deductible depending on how the business is structured and what the property is used for. Splitting the loan does not create deductibility, but it does make it simpler to justify and document.

Matching loan term to business intention

Commercial loan terms typically range from five to 30 years, with most lenders offering 15 to 25-year terms for owner-occupied or investment property. A shorter term increases monthly repayments but reduces total interest. A longer term lowers repayments but increases total cost. The right term depends on how long you intend to hold the property and whether you plan to pay the loan down early or refinance before the term ends.

A Wentworthville business buying a property it plans to occupy for 20 years might choose a 20-year principal and interest loan, aiming to own the property outright by the time the owners retire or sell. A buyer purchasing a property as a stepping stone, intending to sell and upgrade in five to seven years, might choose a longer term to keep repayments lower, knowing they will exit the loan early and the longer term simply provides cash flow relief in the meantime. Loan term is not a commitment to hold the debt that long. It is a tool to manage repayment size and flexibility.

When to refinance or restructure

Refinancing or restructuring makes sense when your circumstances, income, or intentions have changed enough that the current loan no longer fits. This might mean switching from interest-only to principal and interest after an initial growth phase, splitting a single loan into multiple facilities to separate business and investment purposes, or moving from a fixed rate to variable after the fixed term ends. It also makes sense when you want to access equity in the property to fund a second purchase or business expansion.

We regularly see buyers in Wentworthville who structured their loan well at purchase but did not revisit it as the business grew. Five years later, they are still on the same terms, even though revenue has doubled and they could now afford higher repayments or could use equity to expand. Restructuring does not always mean changing lenders. Many lenders will adjust loan structure within the existing facility if the request makes sense and the property valuation and serviceability support it. If the current lender will not, refinancing to a lender who offers the structure you need is worth the effort.
