Top Strategies to Finance an Office Building Purchase

Buying an office building shifts your business from tenant to owner, but the loan structure you choose determines whether that shift strengthens or strains your cash flow.

Most commercial property finance for office purchases settles with a loan to value ratio between 60% and 70%, meaning you need between 30% and 40% of the purchase price as a deposit plus settlement costs. Lenders assess serviceability based on both the rental income the property could generate and your business's capacity to meet repayments if the building sits vacant. That dual assessment shapes which loan structures make sense for your circumstances and which ones leave you exposed.

Commercial LVR and Deposit Requirements

Lenders assess office building purchases differently than owner-occupied commercial property. If you plan to occupy the entire building yourself, serviceability relies entirely on your business income statements and cash flow. If you intend to lease part or all of the space to tenants, lenders factor projected rental income into the assessment, which can improve your borrowing capacity but also requires a leasing strategy before settlement.

Consider a business owner acquiring a two-storey office building in Neutral Bay. The building has an independent tenant on the ground floor with three years remaining on their lease, and the owner plans to occupy the upper level. The lender assessed serviceability using 80% of the ground floor rental income plus the business's existing cash flow, approving a loan amount at 65% LVR. The structure allowed the owner to use tenant income to support the loan while accessing the building for operational use without relocating mid-lease.

Variable vs Fixed Interest Rates for Office Acquisitions

Most office building loans settle on either a variable interest rate or a split between fixed and variable portions. A variable rate gives you access to offset accounts and redraw facilities, which becomes useful if your business generates uneven cash flow or you want to park surplus funds against the loan between major expenses. A fixed rate locks your repayment amount for a set term, usually between one and five years, but removes access to redraw and limits your ability to make additional repayments without triggering break costs.

In our experience, buyers who plan to hold the property long-term and want repayment certainty often fix a portion of the loan while leaving the remainder on a variable rate. That approach balances stability with flexibility, particularly if you expect fluctuating income or plan to make lump sum repayments from business profits.

Loan Structure and Repayment Flexibility

Commercial property loans for office buildings typically offer interest-only repayment options for the first one to five years, followed by principal and interest repayments for the remainder of the term. Interest-only repayments reduce your monthly commitment during the early years of ownership, which can help if you're managing fit-out costs, tenant incentives, or other capital expenses after settlement.

Flexible repayment options also include the ability to link an offset account to a variable rate loan. An offset account holds your business operating funds and reduces the interest charged on your loan balance without locking those funds away. If your business maintains a healthy cash reserve or receives periodic lump sum payments, an offset account can reduce your interest costs while keeping funds accessible.

How Lenders Assess Office Building Purchases

Lenders review your business financials, the property valuation, and the lease profile if tenants are involved. For owner-occupied purchases, they focus on your business's profit and loss statements, balance sheet, and tax returns from the past two years. For tenanted properties, they assess the lease agreements, tenant creditworthiness, and whether the rental income covers the loan repayments at a specified debt service coverage ratio, usually between 1.2 and 1.4 times the annual loan cost.

A commercial property valuation plays a central role in determining the loan amount a lender will approve. Valuers assess comparable sales, rental yields, and the building's condition and location. In areas like the Northern Beaches, where commercial office stock is limited and demand from professional services businesses remains steady, valuations tend to hold well, but lenders still apply conservative LVR ratios to manage risk.

Structuring for Multiple Properties or Business Expansion

If you already own commercial property or plan to acquire additional assets after this purchase, your loan structure should account for future borrowing capacity. Taking out a loan that maximises your current serviceability might limit your ability to access business loans or equipment finance down the line.

Some buyers structure their office building loan with a lower LVR than the maximum available, preserving equity for future use. Others establish a revolving line of credit alongside the primary loan, giving them access to pre-approved funds without reapplying or triggering a new valuation. That setup works well for businesses planning staged expansion or fit-out work after settlement.

Settlement Timing and Pre-Settlement Finance

Office building purchases often involve longer settlement periods than residential transactions, particularly if the property is tenanted or requires planning approvals for intended use changes. If you need to vacate your current premises before settlement, or if you want to begin fit-out work early, pre-settlement finance can bridge the gap.

Pre-settlement finance allows you to draw funds before the main loan settles, usually at a higher interest rate for a short term. It's not a common structure for every purchase, but it solves timing problems when your lease expires before settlement or when securing the property early gives you a commercial advantage.

When Commercial Refinance Makes Sense After Purchase

Once you've owned the property for 12 to 24 months and built equity through either principal repayments or capital growth, refinancing can unlock funds for other business purposes or improve your loan terms. Commercial refinance also makes sense if interest rates have shifted significantly since your original loan settled, or if your business financials have strengthened and you qualify for a higher LVR or lower rate.

Lenders reassess your circumstances during refinance as if it were a new application, so timing matters. Refinancing during a strong financial year gives you better leverage than refinancing after a lean period, even if the property itself has increased in value.

Buying an office building involves more moving parts than most business purchases, and the loan structure you choose shapes your cash flow, flexibility, and capacity to grow.
