Beginner's Guide to Buying an Office Building

Buying an office building means stepping up to commercial property finance, not a standard home loan.

A commercial property loan works differently to residential finance. Lenders assess the business behind the purchase, not just your personal income. They look at trading history, cash flow, the property's income potential, and whether the building suits your industry. For contractors, that often means proving consistent revenue over at least two years and showing how the property supports your operations, whether you're using it as a head office, workshop, or storage hub.

Loan structures vary. You might fix the rate for certainty, use a variable rate with redraw, or split the loan across both. Some lenders offer flexible repayment options tied to your cash flow, which matters when project income fluctuates. Others structure the loan with interest-only periods during fit-out or slow months, then switch to principal and interest once the business stabilises.

Deposit size matters more than it does in residential lending. Most lenders want at least 30% of the purchase price upfront, though some will go to 70% LVR if the property is well-located and generates rental income. If you're buying strata title commercial space, such as a single office suite in a larger complex, some lenders tighten their criteria or charge higher interest rates because of body corporate risk.

How Lenders Assess a Contractor's Application

Lenders assess serviceability based on business income, not just personal earnings. They review your business tax returns, profit and loss statements, and balance sheet. If you operate through a company or trust, they'll look at the entity's financials and may still ask for personal guarantees. For contractors, that means showing steady project work, repeat clients, or long-term contracts that prove income continuity.

Consider a contractor running an electrical business who wants to buy a 400-square-metre office and warehouse in an industrial precinct. The purchase price sits within range for the area, and the contractor has two years of financials showing consistent revenue. The lender assesses the loan based on the business's net profit, existing debts, and the property's valuation. Because the building will be owner-occupied, the lender applies a lower LVR than they would for an investment property. The contractor provides a 30% deposit, and the lender approves a variable rate loan with redraw, allowing the business to access paid-down principal if needed for equipment or short-term working capital.

If your business also needs to finance new equipment or upgrade existing gear around the same time, some lenders will roll that into the property loan or structure it separately. Others prefer to keep equipment finance and property finance separate, especially if the equipment depreciates faster than the building. You can explore options for equipment finance that run alongside the property loan without complicating the security position.

Deposit and Upfront Costs

You'll need at least 30% of the purchase price as a deposit, plus another 5% to 7% for stamp duty, legal fees, valuation, and settlement costs. That means a business buying at a given price point should budget for the deposit and costs combined before signing anything.

Stamp duty on commercial property is higher than residential in most states, and there's no first-home buyer concession. Legal fees also run higher because commercial contracts involve more due diligence, including zoning checks, environmental assessments, and lease reviews if tenants occupy part of the building. The commercial property valuation alone can cost between $2,500 and $5,000 depending on size and location.

If you're buying strata title commercial, factor in body corporate fees and review the strata records for any upcoming levies or disputes. Some lenders reduce the loan amount or increase rates when body corporate fees exceed a certain percentage of the purchase price, because it affects serviceability.

Loan Structure Options That Suit Contractors

Most commercial property loans offer either principal and interest or interest-only repayments during an initial period. Interest-only suits businesses that want to minimise repayments while cash flow is tight, then switch to principal and interest once revenue grows. Variable interest rates give you flexibility to pay down the loan faster or access redraw when you need working capital. Fixed interest rates lock in certainty for three to five years, which helps with budgeting but removes redraw and limits extra repayments.

Some lenders offer a split structure, where part of the loan is fixed and part is variable. That gives you rate certainty on a portion of the debt while keeping flexibility on the rest. Others provide a revolving line of credit secured against the property, which works like a commercial overdraft. You draw down as needed, repay when cash flow allows, and only pay interest on the amount you've used.

If your business is expanding and you need to buy new equipment or upgrade your fleet, you can structure the property loan to include pre-settlement finance for immediate working capital needs, though most brokers recommend keeping those separate. For larger contractors, mezzanine financing can top up the loan if equity falls short, though it comes with higher interest rates and stricter terms.

What Happens If You Need to Refinance or Sell

Refinancing a secured commercial loan works the same way as the original application. The lender reassesses the business, revalues the property, and checks your current debt position. If the building has increased in value or your business has grown, you might access additional equity or negotiate a lower interest rate. If cash flow has tightened, the lender may reduce the loan amount or ask for additional collateral.

Selling an office building while a loan is active requires payout of the debt at settlement. If you're on a fixed rate and exit early, break costs apply. These are calculated based on the lender's cost to unwind the fixed rate, and they can run into tens of thousands of dollars depending on how much time remains on the fixed term and how far rates have moved since you locked in.

If you're considering a move or upsizing within a few years, a variable rate or shorter fixed term gives you more flexibility. If you plan to hold the property long-term and want stable repayments, a longer fixed term might suit your business, but you'll wear the cost if circumstances change.

How a Finance Specialist Helps with Commercial Property Loans

A finance specialist with access to commercial loan options from banks and lenders across Australia can structure the loan to match your business model and cash flow. They'll compare rates, fees, and loan terms, and they'll know which lenders are comfortable with contractor income and which ones require additional documentation or guarantees.

They can also coordinate with your accountant and solicitor to ensure the loan structure fits your tax position and business structure. If you're buying through a company or trust, the finance specialist will work with the lender to set up the security and guarantee arrangements correctly from the start, which avoids delays at settlement.
