Purchasing an Office Building with a Commercial Loan

Buying an office building means securing finance that works differently from residential lending.

The lender assesses your business's ability to service the debt, the income potential of the property itself, and the strength of your deposit. These three factors determine what you can borrow and at what cost. For businesses in Bentleigh East looking to move out of rented premises on Centre Road or establish a permanent base near the commercial precinct around McKinnon, understanding how commercial loans are structured makes the difference between a workable purchase and one that strains cash flow for years.

How Commercial Property Loans Differ from Residential Finance

Commercial property finance is assessed primarily on the income the property generates or your business's capacity to service the debt, not your personal income alone.

Lenders typically require a larger deposit, often 30% to 40% of the purchase price, which translates to a loan-to-value ratio (commercial LVR) of 60% to 70%. The interest rate on a commercial property loan sits higher than residential rates, reflecting the increased risk lenders associate with business ventures. Loan terms usually range from 15 to 25 years, shorter than the 30-year standard in residential lending.

Consider a medical practice looking to purchase a strata title commercial office in one of the buildings along Centre Road. The business generates $850,000 annually with consistent patient numbers. The lender will examine the practice's profit and loss statements, existing business debts, and the lease potential of the property if the practice were to vacate. With a purchase price of $1.2 million, the buyers need at least $360,000 as deposit. The lender structures the loan with a variable interest rate and requires quarterly financial statements for the first two years to monitor business performance.

What Lenders Assess Before Approving Your Application

Lenders evaluate three components: your business financials, the property valuation, and your equity contribution.

Your business needs to demonstrate consistent revenue and profitability, typically through two years of financial statements and tax returns. The commercial property valuation determines how much the lender will advance. Unlike residential properties where comparable sales drive value, commercial properties are valued on their income-producing capacity. If you're buying an office building currently tenanted, the existing lease terms, tenant quality, and market rent comparables all factor into the valuation. Your deposit size directly impacts the interest rate offered and whether the lender requires additional security.

For businesses expanding into larger premises or consolidating operations, the property must support the loan serviceability even during quieter trading periods. In our experience, applicants who can show three years of consistent revenue rather than two receive more favourable loan structures, particularly when buying in areas like Bentleigh East where commercial property values have remained stable due to the established residential base and proximity to Monash Medical Centre employment.

Structuring the Loan for Cash Flow and Growth

The loan structure you choose impacts your business's cash flow more than the interest rate alone.

Flexible repayment options allow you to make principal and interest payments during strong trading periods and interest-only payments when cash is tight. A progressive drawdown works if you're purchasing land and constructing an office, releasing funds at each stage of the build. Some lenders offer a revolving line of credit secured against the property, providing working capital access without a separate business loan application.

Consider a scenario where an accounting firm purchases a two-storey office building for $1.6 million in the Bentleigh East commercial zone, planning to occupy the ground floor and lease the upper level to another business. The existing tenant pays $42,000 annually on a lease with three years remaining. The buyers structure the loan with interest-only payments for the first three years, matching the tenant's lease term. During this period, rental income offsets part of the loan cost while the business builds up reserves. After three years, they switch to principal and interest repayments, using the cash buffer they've accumulated. This approach meant the business didn't stretch its cash flow during the transition into the new premises.

Variable or Fixed Interest Rates for Commercial Property

Most commercial borrowers choose variable interest rates because they offer flexibility to make additional repayments without penalty.

Fixed interest rates provide certainty over repayment amounts, useful if your business operates on tight margins and can't absorb rate increases. However, fixed rate commercial loans typically come with restrictions on additional repayments and significant break costs if you refinance or sell before the fixed term ends. With commercial lending, fixed terms rarely extend beyond five years, unlike residential mortgages where you might fix for seven years or longer.

Variable rates allow you to access redraw facilities if your loan permits it, letting you pull back extra repayments if the business needs working capital. This becomes relevant for professional services firms in Bentleigh East where income can fluctuate based on client activity or seasonal patterns.

Using Existing Property as Security

You can use equity in your home or another commercial property as collateral to reduce the deposit required for the office purchase.

This approach, often called cross-collateralisation, allows you to access commercial finance with a smaller cash deposit. The risk is that both properties are secured against the loan, meaning if your business cannot meet repayments, the lender can claim both assets. Some buyers prefer to keep securities separate, using a secured commercial loan for the office and maintaining their home as untouched equity.

For self-employed borrowers or those with complex business structures, demonstrating serviceability becomes more important than for PAYG employees. Lenders want to see that after covering the new loan repayments, your business still generates sufficient income for operating expenses, business growth, and your personal drawings.

When to Consider Commercial Refinance

Commercial refinance makes sense when your business has grown, property values have increased, or you need to restructure debt.

If you purchased your office building three years ago with a 65% LVR and the property has appreciated while you've reduced the loan balance, you might now sit at 50% LVR. This equity position often unlocks better interest rates or allows you to draw funds for business expansion without needing a separate loan. Refinancing can also consolidate multiple business debts into one facility secured against your office, simplifying repayments and potentially reducing overall interest costs.

TM Finance Group works with lenders across Australia, which matters when you're refinancing because commercial lending appetite varies significantly between banks and specialist lenders. Access to multiple commercial loan options means finding terms that match your current business position rather than accepting what your existing lender offers.
