Secured Business Loans Anchor Most Commercial Property Purchases
A secured business loan uses the commercial property you're purchasing as collateral, which typically reduces your interest rate by 1% to 2% compared to unsecured business finance. The property itself becomes security for the loan amount, giving lenders confidence to offer longer loan terms and larger sums. This structure works particularly well in north-east Melbourne precincts like Doncaster and Bulleen, where established commercial office buildings often come with existing tenant income that services the debt from day one.
Consider a business acquiring a two-level office building in the Bulleen industrial precinct. The purchase requires a loan structure that accounts for existing lease agreements, building condition, and the capacity to cover repayments during any vacancy period. A secured business loan allows the borrower to use rental income as part of their debt service coverage ratio calculation, which matters when lenders assess whether your cashflow can sustain the commitment. Most lenders want to see a ratio of at least 1.25, meaning your income exceeds debt repayments by 25% after operating expenses.
The difference between variable interest rate and fixed interest rate options becomes material over a 15 or 20-year commercial loan term. Variable rates typically sit lower at the outset and include redraw facilities, letting you access any extra repayments you've made during strong trading periods. Fixed rates lock in certainty but remove that flexibility. Many borrowers split the loan amount across both structures, fixing 50% to 70% for rate protection while keeping the remainder variable for operational flexibility.
How Lenders Assess Commercial Property Loan Applications
Lenders evaluate three core elements when you apply for commercial loans to purchase an office building: your business financial statements, the property's income-producing capacity, and your business credit score. Business financial statements need to cover at least two years of trading, showing consistent revenue and a clear cashflow forecast that demonstrates how rental income or business operations will service the loan. Lenders typically assess profit and loss statements, balance sheets, and tax returns to calculate your debt service coverage ratio.
The property itself undergoes a commercial valuation that examines current tenancy agreements, lease terms, building condition, and comparable sales in the area. In suburbs like Templestowe and Doncaster, where commercial office stock varies widely in age and fit-out, this valuation directly influences the loan amount a lender will approve. Most lenders will finance 60% to 70% of the property's valued amount for established businesses with strong financials, though that percentage drops for startup business loans or businesses with limited trading history.
Your business credit score affects both approval and the interest rate offered. A score above 650 generally qualifies for standard commercial lending rates, while scores below that threshold may require additional security or attract a risk margin on the rate. If your business is structured as a company, lenders will also review director guarantees and may assess personal financial positions to support the application.
Deposit and Settlement Cost Planning for Commercial Purchases
Commercial office building purchases require a deposit of 30% to 40% of the purchase amount, significantly higher than residential property. This deposit can come from business savings, director loans, or equity in other property holdings. Settlement costs add another layer, including legal fees for commercial conveyancing, building and pest inspections, commercial valuation fees, and stamp duty calculated on the full purchase amount.
In our experience with businesses acquiring property in the north-east corridor, the settlement timeline for commercial transactions runs longer than residential deals. Commercial contracts often include longer due diligence periods, allowing buyers to review existing leases, conduct building inspections, and arrange formal valuations. This extended timeline works in your favour if you need to arrange finance through multiple lenders or structure the deal as a business acquisition that includes the property and an existing operation.
Loan structure decisions made before settlement affect your cash flow for years afterward. A principal and interest loan structure reduces the loan balance with each payment but requires higher monthly repayments. An interest-only period of one to five years keeps repayments lower, preserving working capital for fit-outs, tenant improvements, or business expansion. Many buyers in the Doncaster and Fairfield areas use interest-only periods to manage cashflow during the first years of ownership, particularly when taking on buildings that need refurbishment or re-leasing.

Variable Rate Flexibility vs Fixed Rate Certainty
Variable interest rate loans for commercial property include features that fixed loans don't. Redraw facilities let you pull back extra repayments when you need working capital, a genuine advantage during periods when tenant vacancies reduce income or when opportunities arise to purchase adjoining properties. You can also make unlimited additional repayments without penalty, which reduces interest costs over the loan term.
Fixed interest rate loans remove uncertainty around repayments, which matters when you're forecasting business budgets across multi-year periods. The rate locks in for one to five years, depending on the lender and loan product. If rates rise during that period, your repayments stay unchanged. If rates fall, you're locked into the higher rate unless you're willing to pay break costs to exit the fixed term early. Most commercial borrowers fix a portion of the loan amount rather than the full sum, balancing certainty with flexibility.
A split loan structure might allocate 60% of the loan to a fixed rate and 40% to a variable rate with redraw. This approach lets you forecast the majority of your repayments with confidence while maintaining access to flexible repayment options on the variable portion. As an example, a business purchasing a commercial office building in Templestowe might fix the portion of the loan that matches confirmed long-term lease income, keeping the remainder variable to handle vacancy risk or capital improvements.
Express Approval Processes for Established Businesses
Some lenders now offer express approval pathways for established businesses with clean financials and strong cash flow. These fast business loans still require full documentation, but the assessment timeline compresses from four to six weeks down to 10 to 14 days. Express approval works when your business has been operating for at least three years, shows consistent profitability, and when the property you're purchasing comes with secure tenancy agreements already in place.
The key to accessing these faster timelines is preparation. Lenders need up-to-date business financial statements, a current cashflow forecast, a detailed business plan that explains how the property purchase supports business growth, and evidence that your debt service coverage ratio comfortably exceeds lender minimums. If you're buying in a high-demand area like the Doncaster commercial precinct, speed matters. Properties with strong tenant covenants and well-maintained buildings move quickly, and express approval can be the difference between securing the property and losing it to another buyer.
Access business loan options from banks and lenders across Australia by working with a broker who holds commercial lending relationships beyond the major banks. Second-tier lenders and specialist commercial financiers often assess applications with more flexibility around loan structure, especially when the property itself is well-located and income-producing. Some lenders also offer progressive drawdown facilities for commercial purchases that include planned renovations, releasing funds in stages as work completes rather than requiring you to arrange separate working capital finance.
How Existing Tenancy Agreements Affect Loan Approval
An office building with long-term leases in place attracts better lending terms than a vacant building or one with short-term tenants. Lenders view rental income from creditworthy tenants as stable cashflow that directly services the loan, which reduces lending risk and often translates into a lower interest rate. When assessing the property, lenders examine lease terms, tenant payment history, and the financial strength of tenants themselves.
Consider a scenario where you're purchasing a commercial office building in Bulleen with three tenants on staggered lease terms. One tenant is a government agency on a five-year lease, another is a professional services firm on a three-year lease with two years remaining, and the third is a small business on a one-year rolling lease. The lender will weight that government tenancy heavily in their assessment, viewing it as low-risk income. The professional services lease adds strength, while the rolling lease gets minimal credit in cashflow calculations. This tenancy mix might support a 65% loan-to-value ratio, whereas a building fully leased to the government agency could attract 70%.
Vacant buildings or those requiring significant refurbishment need a different approach. Some lenders offer business expansion loans that combine acquisition and refurbishment costs into one facility, with an interest-only period during construction and a progressive drawdown structure. Others require you to demonstrate sufficient working capital to cover loan repayments during the vacancy period, usually by showing liquid business assets or director guarantees supported by personal property equity.
When to Consider an Unsecured Business Loan for Deposit Funding
An unsecured business loan can cover part of your deposit or settlement costs if you lack sufficient cash reserves but have strong business income and a solid business credit score. These loans don't require property as collateral, instead relying on your business's trading history and financial position. Interest rates sit higher than secured loans, typically by 3% to 5%, but the approval process moves faster and doesn't require property valuations.
This approach works when you need to move quickly on a commercial property opportunity and your business generates consistent revenue that can service both the unsecured loan and the larger secured facility. As an example, a professional services business with high monthly cashflow might use an unsecured business loan to bridge a deposit shortfall, then refinance that debt into the main commercial loan once settlement completes and the property provides security.
Unsecured business finance also suits situations where you're purchasing a commercial property but need to preserve working capital for immediate fit-out or tenant improvements. Rather than depleting business savings for the full deposit, you fund part of it through an unsecured loan and keep cash available for the work needed to make the building operational. The trade-off is higher interest costs in the short term against maintained operational flexibility, which often makes sense when rental income will begin flowing within weeks of settlement.

Frequently Asked Questions
What deposit do I need to purchase a commercial office building?
Most lenders require a deposit of 30% to 40% of the property's purchase amount for commercial office buildings. This can come from business savings, director loans, or equity in other properties you own.
How does a secured business loan differ from an unsecured business loan?
A secured business loan uses the property as collateral, typically offering interest rates 1% to 2% lower than unsecured finance. Unsecured business loans don't require property security but charge higher rates and suit smaller amounts or short-term needs.
What is a debt service coverage ratio and why does it matter?
The debt service coverage ratio compares your income to loan repayments after operating expenses. Lenders typically want to see a ratio of at least 1.25, meaning your income exceeds debt repayments by 25%, to approve commercial property loans.
Should I choose a variable or fixed interest rate for a commercial property loan?
Variable rates offer redraw facilities and repayment flexibility, while fixed rates provide repayment certainty for one to five years. Many borrowers split their loan, fixing 50% to 70% for stability and keeping the rest variable for operational flexibility.
How do existing tenancy agreements affect my loan approval?
Properties with long-term leases to creditworthy tenants attract better lending terms because rental income reduces lender risk. Government or corporate tenants on multi-year leases often support higher loan amounts and lower interest rates.
