Commercial vs. Residential Investment: Lending Differences Explained

Experienced residential investors often consider commercial property as the next step, higher yields, longer leases, tenant-paid outgoings. The investment case can look strong. But commercial lending is a fundamentally different product to residential investment finance, and the differences have direct consequences for which properties you can buy, at what price, and how the cash flow works from day one.

This guide is for residential investors who are familiar with residential lending and are considering commercial for the first time.

The Deposit: The First Significant Difference

Residential investment: up to 80% LVR without LMI, 90% with. Commercial investment: typically 60-75% LVR, no LMI equivalent in most cases. On a $1 million residential property at 80%, you need $200,000 deposit. On the same $1 million commercial property at 65%, you need $350,000. That’s 75% more deposit for the same purchase price. The deposit differential is the primary reason commercial property is less accessible than residential, even when the yield looks more attractive on paper. Commercial investors should plan for a 30-35% deposit on their first purchase.

Interest Rates: Commercial Loans Cost More

Commercial rates are higher than residential investment rates, typically 0.5-2% above equivalent residential rates, sometimes more for non-standard assets or non-bank lenders. Commercial loans also have shorter maximum terms, 15-25 years rather than 30 years. Shorter terms increase periodic repayments, which affects cash flow particularly in the early years. The rate premium and shorter term together mean commercial cash flow projections need to account for higher holding costs than residential at the same loan amount.

Serviceability: How It’s Assessed Differently

Residential investment serviceability is primarily assessed on personal income, with rental income included at a shaded rate (typically 75-80% of gross). The framework is standardised across lenders under APRA guidelines.

Commercial serviceability is assessed differently. The key metric is the Interest Coverage Ratio (ICR), the ratio of net rental income to interest expense, typically required to be 1.2-1.5x. Lenders apply higher stress buffers than APRA requires for residential. And unlike residential, there is no standardised assessment framework, lenders have more discretion, and two lenders can reach materially different conclusions on the same commercial application based on how they weight different factors.

Asset Assessment: What Lenders Look At

Residential assessment focuses primarily on the borrower’s serviceability. The property matters, valuation, location, condition, but the product is largely standardised because residential properties are liquid and easily valued by comparable sales.

Commercial assessment adds a significant layer of asset-specific scrutiny. Lenders evaluate: whether the property type is within their credit policy (some lenders specifically exclude retail, hospitality, or certain regional markets); the lease structure (term remaining, market rent, tenant covenant strength, rent review mechanisms); the physical condition and marketability of the asset; and the valuation methodology, which is more complex than residential, commercial valuers use capitalisation of income, direct comparison and sometimes discounted cash flow analysis.

This means that two properties at the same price in the same suburb can attract very different lender appetite depending on asset type, lease and tenant quality. Commercial investing is asset-specific in a way residential isn’t.

The Documentation Is Heavier

Residential investment documentation is well understood and largely standardised. Commercial investment documentation is substantially more extensive: two to three years of business financials if self-employed or if commercial income is the primary income source; commercial property valuations from approved commercial valuers (slower and more expensive than residential valuations); all existing lease documentation with schedules; evidence of tenant creditworthiness; and for larger transactions, sometimes a formal investment brief explaining the acquisition rationale.

Loan Terms and Structure

Commercial loans often include review dates, provisions at which the lender reassesses the loan’s terms. These don’t appear in standard residential mortgages. Fixed rate options exist but are less uniformly available. Interest-only periods are possible but less standardised. These structural differences mean commercial investment finance requires more active management than a set-and-forget residential mortgage.

When Commercial Investment Makes Sense

Commercial investment lending makes sense for investors who have sufficient equity for the higher deposit (30-35%), a target property with strong lease fundamentals and a quality tenant, a cash flow position that can sustain the higher commercial rates, and a clear strategy for the investment hold. The worst commercial property outcomes come from investors who underestimate the deposit requirement, overestimate the LVR, or don’t factor in the higher rate when modelling cash flow.
