Commercial lending repayment structures directly impact your cash flow, total borrowing costs, and loan serviceability. The three main options - Principal & Interest (P&I), Interest Only (IO), and Interest Capitalisation (ICAP) - each serve different business objectives and financial circumstances.
Understanding these structures helps you negotiate better loan terms and align your financing with your property's income potential. The choice affects everything from monthly payments to total interest costs over the loan term.
Commercial Loan Terms by Asset Type
Loan terms vary significantly based on the underlying asset and its income-generating capacity. Different asset classes carry different risk profiles for lenders, which may result in varying maximum loan terms subject to individual assessment.
Residential investment properties typically qualify for terms up to 30 years, subject to lender assessment. Commercial properties also reach up to 30 years, though this depends on factors like property quality, location, and tenant strength.
Business cash flow loans secured by a General Security Agreement (GSA) usually cap at 10 years. Equipment financing generally limits to 5 years, reflecting the asset's depreciation profile. Unsecured business loans rarely exceed 5 years due to higher risk exposure.
The key principle is matching loan terms to asset life and income generation capacity. A 25-year loan on equipment that becomes obsolete in 5 years creates obvious problems.

WALE: The Commercial Property Metric That Matters
Weighted Average Lease Expiry (WALE) measures the average time until all leases in a commercial property expire. This metric directly influences loan terms and interest rates for multi-tenanted commercial properties.
A property with a WALE of 8 years offers more income certainty than one with a WALE of 2 years. Lenders view longer WALE properties as lower risk, often resulting in better loan terms and higher loan-to-value ratios. LVR limits vary by lender and are subject to individual assessment.
WALE calculations consider both lease length and rental value. A single large tenant on a 10-year lease carries more weight than multiple small tenants on shorter terms. This affects both loan approval and ongoing loan management.
Properties with short WALE periods may face loan review requirements as lease expiry approaches. Some lenders require formal revaluation or income confirmation when significant leases approach expiry.
Principal & Interest: The Standard Approach
Principal & Interest repayments gradually reduce your loan balance over the specified term. Commercial P&I loans typically amortise over 25 years, though terms up to 30 years may be available subject to lender assessment.
Monthly repayments cover both interest charges and principal reduction. This means your loan balance decreases each month, building equity in the underlying asset over time.
Repayment amounts vary with interest rate changes on variable rate facilities. Fixed rate periods provide payment certainty but limit flexibility to benefit from rate reductions.
P&I structures work well for cash flow positive properties where rental income comfortably covers loan repayments. They suit investors focused on long-term wealth building through debt reduction and capital growth.
Interest Only: Maximising Cash Flow
Interest Only repayments cover interest charges without reducing the principal balance. Commercial lenders typically allow IO periods up to 5 years, though this varies by lender and borrower strength.
IO loans usually carry higher interest rates than equivalent P&I facilities. The rate premium reflects the lender's increased risk exposure from the unchanged principal balance. Fees and rates vary by lender and are subject to change.
After the IO period expires, loans typically revert to P&I repayments for the remaining term. A 25-year loan with 5 years IO means 20 years of P&I repayments, resulting in higher ongoing repayments than a full P&I structure.
IO structures suit developments, major renovations, or properties requiring significant capital expenditure. They provide cash flow relief during periods of reduced income or high capital requirements.
Interest Capitalisation: The Ultimate Cash Flow Solution
Interest Capitalisation (ICAP) adds interest charges to the loan balance instead of requiring monthly payments. The total debt grows over time as unpaid interest compounds.
ICAP facilities typically operate for shorter periods than traditional IO loans. They suit specific situations like major developments, significant property improvements, or temporary cash flow disruptions.
The compounding effect means total borrowing costs exceed other repayment structures. A $500,000 loan at 6% annual interest may grow to approximately $530,000 after one year of capitalisation, subject to actual rate and fee calculations.
Lenders reserve ICAP structures for strong borrowers with clear exit strategies. They require detailed cash flow projections showing ability to service debt when capitalisation ends.
Choosing the Right Structure for Your Situation
The optimal repayment structure depends on your cash flow capacity, investment strategy, and property characteristics. P&I structures suit stable, cash flow positive properties with long-term hold strategies.
IO structures work for properties requiring capital investment or experiencing temporary income disruption. They also suit investors prioritising cash flow for other opportunities or debt service on multiple properties.
ICAP structures apply to specific situations requiring maximum cash flow preservation. They suit developments, major refurbishments, or bridging finance scenarios with defined end dates.

Tax Implications of Different Repayment Structures
Repayment structures affect tax deductions and cash flow timing. Interest payments on investment properties may be tax deductible, regardless of whether you pay monthly or capitalise the interest.
P&I repayments provide steady annual deductions through interest payments. Principal repayments aren't deductible but build equity that may qualify for capital gains concessions on disposal.
IO structures can maximise annual interest deductions while preserving cash for other deductible investments or business activities. This may improve overall tax efficiency in some circumstances.
ICAP structures defer cash outflows but still generate annual interest deductions based on the capitalised amounts. This can create tax benefits in early years with cash flow pressure in later periods.
Tax treatment varies - speak with your accountant to understand the implications for your specific circumstances. The interaction between loan structure and tax outcomes requires careful analysis of your complete financial position.
