Purchasing a business park brings together property investment and operational strategy in a way that residential finance never captures.
Construction professionals buying workshop space, warehousing, or industrial estates face funding decisions that hinge on loan structure, drawdown timing, and how lenders assess income from both contracting work and future tenancies. The deposit requirement alone typically sits at 30% to 40% of the purchase price, and the way you present trading history and rental projections determines whether a lender treats the acquisition as investment property or business expansion.
How Lenders Assess Income When You're Buying and Occupying
Lenders evaluate your borrowing capacity using a combination of business trading income and any rental income the property will generate. If you're purchasing a business park to occupy one unit and lease the remainder, the assessment includes your ABN trading history over the past two years, current contract pipeline, and the rental yield from tenanted space. Most lenders apply a discount factor of around 80% to projected commercial rent when calculating serviceability, which means a property generating $100,000 in annual rent is assessed at roughly $80,000 for loan purposes.
Consider a building company purchasing a 1,200-square-metre industrial complex with three units. The business occupies one 400-square-metre workshop for equipment storage and fabrication, while leasing the remaining two units to other trades at $24,000 per annum each. The lender assesses the $48,000 rental income at 80%, adding $38,400 to the director's trading income when calculating how much can be borrowed. The deposit was 35%, and the loan was structured as a commercial property loan with principal and interest repayments over 15 years, keeping monthly commitments within the cash flow generated by existing contracts and tenant rent.
Strata Title vs Whole Title: What Changes in the Loan Structure
Buying a single strata title unit within a business park differs from purchasing the entire complex under one title. Strata title commercial property typically requires a smaller deposit and shorter settlement period, but lenders often price the loan with a margin increase of 0.20% to 0.50% due to perceived liquidity risk. Whole title acquisitions, particularly those with multiple tenancies, are assessed on the strength of lease agreements and the diversity of tenant income.
If you're purchasing strata title commercial space, lenders will review the strata report, sinking fund balance, and any upcoming levies that affect cash flow. A hydraulics contractor buying a 300-square-metre unit in a Western Sydney business park faced a special levy of $18,000 for car park resurfacing, flagged during due diligence. The lender required evidence that the levy was either paid before settlement or factored into the loan amount, as outstanding strata debts can delay settlement and affect registered security.

When Pre-Settlement Finance Covers the Deposit Gap
Construction professionals often hold significant equity in residential property or plant and equipment, but accessing that equity before settlement can determine whether a purchase proceeds. Pre-settlement finance allows you to draw against an approved loan before the commercial property settles, covering the deposit or urgent fit-out costs. This is particularly relevant when selling an existing asset to fund the deposit, but the sale settlement falls after the business park purchase date.
A concreting business committed to a business park purchase with settlement in six weeks, but the sale of their old yard wasn't settling for another ten weeks. The broker arranged pre-settlement finance secured against the incoming sale property, releasing the deposit funds on time. Once the sale completed, the funds cleared the pre-settlement facility and the remaining balance was rolled into the standard commercial finance structure. The cost was an additional interest margin for the short-term facility, but it kept the purchase on schedule without renegotiating terms with the vendor.
How Commercial LVR Affects Your Interest Rate and Flexibility
Commercial property loans are priced on a tiered structure where the loan-to-value ratio directly influences the interest rate and the lender's willingness to offer features like redraw or offset. A commercial LVR below 65% typically attracts the lowest margin, while loans between 65% and 70% may see a rate increase of 0.30% to 0.60%. Above 70%, lender appetite narrows and pricing rises further.
If your deposit pushes the LVR below 60%, you gain access to more flexible loan terms, including the ability to redraw from principal payments or negotiate a revolving line of credit component. This matters when upcoming projects require working capital or when equipment purchases arise mid-year. Variable interest rate structures dominate the commercial market, though some lenders offer fixed interest rate periods of up to five years for owner-occupied business property. Fixing part of the loan provides repayment certainty, particularly when long-term leases are in place and rent covers a portion of the commitment.
Valuation Risk and How It Derails Settlement
Commercial property valuation is undertaken by a lender-appointed valuer who assesses comparable sales, tenancy agreements, and the income-generating potential of the site. If the valuation comes in below the purchase price, the lender will only advance funds based on the lower figure, leaving you to cover the shortfall from your own resources or renegotiate with the vendor.
In our experience, valuation shortfalls occur most often in tightly held industrial precincts where recent sales data is sparse. A formwork contractor agreed to purchase a business park in a regional centre for $1.4 million, but the valuation returned at $1.25 million. The lender approved a loan based on the $1.25 million figure, which meant the borrower needed to find an additional $150,000 to settle. The buyer renegotiated the price down to $1.3 million and increased the deposit slightly to meet the funding gap, but the process delayed settlement by three weeks.
Why Loan Structure Matters More Than Rate Alone
The way a commercial loan is structured affects how you manage the debt over time, particularly when business revenue fluctuates or opportunities arise to expand. A loan with principal and interest repayments reduces the debt steadily and builds equity, while interest-only terms lower monthly commitments and preserve cash flow in the short term. Most lenders offer interest-only periods of up to five years on commercial property finance, after which the loan reverts to principal and interest unless renegotiated.
If the business park generates rental income, aligning the loan structure with lease expiry dates can provide certainty when tenants vacate or rents are reviewed. A scaffolding company with two tenants on three-year leases structured the loan with a five-year interest-only period, knowing that rental income would remain stable and allow time to assess whether the business needed the additional space once leases expired. After four years, the company expanded into one of the tenanted units, and the loan was refinanced to reflect the change in income and occupancy.
Purchasing a business park as a construction professional involves balancing immediate funding needs with long-term business goals. The structure you choose now determines your flexibility later, and working with a commercial finance and mortgage broker who understands both property and business lending ensures the loan matches how your business actually operates.

Frequently Asked Questions
What deposit is required to purchase a business park in Australia?
Most lenders require a deposit of 30% to 40% of the purchase price for a commercial property loan when buying a business park. The exact amount depends on the loan-to-value ratio the lender is willing to support and whether you're occupying the property or leasing it entirely.
How do lenders assess rental income for a business park purchase?
Lenders typically apply a discount factor of around 80% to projected or actual commercial rent when calculating serviceability. This means if the property generates $100,000 in annual rent, only $80,000 is counted toward your borrowing capacity.
What happens if the commercial property valuation comes in below the purchase price?
The lender will only advance funds based on the lower valuation figure, leaving you to cover the shortfall from your own resources or renegotiate the purchase price with the vendor. Valuation shortfalls are more common in tightly held industrial areas with limited recent sales data.
Can I use pre-settlement finance to cover the deposit on a business park?
Yes, pre-settlement finance allows you to draw against an approved loan before the commercial property settles, which can cover the deposit or urgent costs if your own sale or funds are delayed. Once your sale completes, the funds clear the pre-settlement facility and roll into the standard loan structure.
Should I choose a fixed or variable interest rate for a commercial property loan?
Variable interest rate structures are more common in commercial lending and offer flexibility for redraw or additional repayments. Fixed interest rate periods of up to five years are available and provide repayment certainty, particularly when long-term leases are in place and rental income is stable.
