Financing Office Space: What Lenders Actually Assess

Lenders evaluate office property loans differently to residential mortgages. The primary focus is rental yield, tenant quality, and your capacity to service debt from rental income or business cashflow. Lenders typically advance 60% to 70% of the property's commercial property valuation, though some may extend to 80% where a strong lease covenant exists or the borrower demonstrates substantial business equity.

Consider a Melbourne-based professional services firm acquiring a 250-square-metre office in the Southbank precinct. The purchase required a loan structure that balanced upfront capital preservation with the flexibility to expand into adjacent tenancies later. The borrower secured 65% leverage using a combination of fixed and variable interest rate facilities, with the fixed portion protecting against rate movements during the first three years when cashflow would be tightest. The variable component included redraw and offset features that allowed surplus business income to reduce interest costs without locking funds away.

The loan structure itself became as important as the rate. Office acquisitions often benefit from split facilities because they mirror the way businesses actually use capital. One portion covers the purchase, another handles fitout or working capital, and a third may be held as a commercial property loan revolving line of credit for future expansion or equipment purchases.

How Loan-to-Value Ratios Shape Your Deposit and Structure

Commercial LVR settings determine not just your deposit size but also the loan structure available to you. At 70% LVR, most lenders treat the proposition as standard commercial real estate financing. Above that threshold, they may require additional security, personal guarantees, or higher interest margins. Below 60%, you may access more flexible loan terms and lower rates, but you tie up more capital upfront.

The trade-off is rarely straightforward. A business with strong cashflow may prefer to borrow at 70% and retain capital for fitout, technology, or hiring. Another may prefer a 50% LVR to reduce ongoing interest expense and free up serviceability for future borrowing. Neither approach is inherently superior. The right choice depends on your business's growth trajectory, the quality of the lease in place, and whether the office will be owner-occupied or tenanted.

When the Southbank office was being financed, the borrower initially planned a 60% LVR to minimise interest costs. After modelling the impact of retaining an additional $150,000 in working capital, they opted for 65% LVR and deployed the retained funds into a separate revenue-generating contract. The additional interest cost was offset within eight months, and the business maintained liquidity through a period of staff expansion.

Owner-Occupied vs Investment: How Serviceability Changes

Serviceability for owner-occupied office finance is assessed against your business's net profit, director income, and existing debt commitments. Lenders typically apply a coverage ratio of 1.25 to 1.5, meaning your cashflow must exceed the proposed loan repayments by at least 25% to 50%. For investment properties, lenders assess rental income and may apply a discount or shadow rate to stress-test the servicing buffer.

If you occupy the office yourself, lenders will scrutinise your business financials, including profit and loss statements, tax returns, and debtor ledgers. If you lease the property to a third party, the strength of the lease and tenant covenant becomes central. A five-year lease to a ASX-listed tenant will support higher leverage and lower rates than a short-term lease to a startup.

In our experience, businesses that plan to occupy part of the building and lease the remainder often encounter friction during the assessment. Lenders may split the application into two components: one assessed on business serviceability, the other on rental income. This can introduce complexity, but it also opens the door to more tailored loan structures, including progressive drawdown facilities that release funds as tenancies are filled.

Fixed vs Variable: Structuring Around Rate Movements

Fixed interest rate terms for commercial property finance typically range from one to five years, with three-year terms being the most common. Fixing provides certainty during the early phase of ownership when budgets are tightest and rental income may not yet cover all outgoings. Variable facilities offer redraw, offset, and the ability to make lump-sum repayments without penalty, which suits businesses with irregular cashflow or plans to inject surplus income.

Many borrowers split their facility. A fixed portion anchors the repayment budget, while a variable portion absorbs surplus cashflow and provides access to working capital via redraw. This dual structure is particularly useful for office acquisitions in areas like Docklands or the Cremorne precinct, where fitout costs can be substantial and staged over several months.

The risk of fixing too much lies in prepayment penalties if you sell, refinance, or pay down the loan early. The risk of staying entirely variable is budget uncertainty, particularly if rates rise during a period when vacancy or tenant default affects your income. The middle path tends to be a 50-50 split, though the right balance depends on your cashflow predictability and risk tolerance.

When Bridging Finance Fits Office Acquisitions

Commercial bridging finance is used when settlement timing doesn't align with available capital. This might occur if you're selling one office to buy another, waiting on a business sale to complete, or expecting a capital injection from a partner or investor. Bridging terms are short, typically six to twelve months, and interest rates sit above standard commercial property loan rates due to the higher risk and expedited approval process.

Bridging is not a substitute for poor planning, but it is a legitimate tool when the opportunity cost of delay exceeds the cost of short-term finance. We regularly see this in scenarios where a business identifies an office building in a tightly held precinct like South Yarra or Richmond and must move quickly to secure it before another buyer does.

The key is having a clear exit strategy. Lenders will want to see evidence of the incoming funds, whether that's a signed contract of sale, a committed equity partner, or a formal lending approval for the end debt. Without that, bridging becomes speculative, and most lenders will decline.

Refinancing Office Loans: When and Why It Makes Sense

Commercial refinance becomes relevant when your existing loan no longer reflects your business's position or the property's performance. This might mean accessing equity for expansion, restructuring to improve cashflow, or moving to a lender that offers more flexible repayment options. Refinancing also makes sense if your original loan was structured conservatively and you now qualify for a higher LVR or lower margin.

Timing matters. If you're still within a fixed rate period, break costs may outweigh the benefit of switching. If your business has grown and you're now servicing the loan comfortably, you may be able to negotiate better terms without changing lenders. If the office has appreciated or you've improved the lease profile, you may be able to draw equity without selling.

Refinancing an office property loan is not a set-and-forget exercise. As your business evolves, your finance should adapt. That might mean splitting a facility to fund fitout, converting part of the loan to interest-only to free up cashflow, or consolidating multiple facilities under one lender to reduce administration and improve pricing.

For clients holding office assets in established Melbourne precincts, we often review the loan structure every two to three years, not because the existing facility is problematic, but because business priorities shift. What worked at acquisition may not suit a business that's since doubled in size, taken on new partners, or moved into adjacent property.

Structuring for Flexibility: Revolving Credit and Progressive Drawdown

A revolving line of credit attached to your office loan allows you to draw and repay funds as needed, using the property as collateral. This is useful for managing fitout costs, covering working capital gaps, or funding equipment purchases without applying for separate finance. The interest rate is typically variable, and you only pay interest on the drawn balance.

Progressive drawdown structures are common in commercial construction loan scenarios, but they also apply to office fitouts and staged acquisitions. Instead of drawing the full loan amount at settlement, you draw funds as costs are incurred. This reduces interest costs during the fitout period and aligns cashflow with expenditure.

These structures introduce complexity, but they also introduce control. A business that can draw and repay funds flexibly is better positioned to respond to growth opportunities, manage seasonal cashflow variation, or absorb unexpected costs without needing to approach the lender for approval each time.

What Happens When You Outgrow the Facility

Businesses that acquire office space often do so with a three-to-five-year view. But circumstances change. You may take on additional tenants, expand into adjacent space, or decide to develop the site. When that happens, your original loan structure may no longer fit.

Expanding into additional space often requires a top-up or second facility. If the building has appreciated or you've paid down debt, you may be able to access equity without selling. If you're planning a material refurbishment or subdivision, you may need to refinance into a facility that includes a fitout or development component.

We've seen clients in the Richmond and Collingwood office markets move from a single owner-occupied tenancy to multi-tenanted strata title commercial buildings over the course of five years. The finance evolved from a straightforward commercial property loan to a split structure with investment and development components. The lender remained the same, but the facility was restructured twice to accommodate the changing use and ownership model.

Frequently Asked Questions

What LVR can I expect when financing an office property?

Most lenders advance 60% to 70% of the property's valuation for standard commercial real estate financing. Higher LVR may be available with strong tenant covenants or additional security, while lower LVR often unlocks better rates and more flexible terms.

How do lenders assess serviceability for owner-occupied office loans?

Lenders assess your business's net profit, director income, and existing debt commitments, typically requiring cashflow to exceed loan repayments by 25% to 50%. They will review financial statements, tax returns, and debtor ledgers as part of the assessment.

When does commercial bridging finance make sense for office acquisitions?

Bridging finance is used when settlement timing doesn't align with available capital, such as selling one office to buy another or waiting on a business sale. It requires a clear exit strategy and evidence of incoming funds to secure approval.

Should I fix or keep my office loan on a variable rate?

Fixed rates provide budget certainty during early ownership when cashflow is tightest, while variable rates offer redraw and flexibility for irregular cashflow. Many borrowers split their facility to balance certainty with access to surplus funds.

What is a revolving line of credit and how does it help with office financing?

A revolving line of credit lets you draw and repay funds as needed using the office property as collateral. It's useful for fitout costs, working capital, or equipment purchases, with interest charged only on the drawn balance.
