Comparing investment loans means looking beyond the advertised interest rate to find the product that supports your specific property strategy and cash flow position.
When you assess loan options for a rental property, the headline rate tells only part of the story. The features attached to that rate, such as offset availability, repayment flexibility, and loan structure, determine whether the product suits your borrowing needs and investment timeline. A loan with a slightly higher rate but full offset access may deliver better after-tax outcomes than a lower rate product without that feature.
Interest Rate Structure: Variable or Fixed
Variable rates move with the market and allow you to make extra repayments or access offset accounts. Fixed rates lock in your repayment amount for a set period, usually one to five years, but typically restrict additional repayments and do not include offset functionality.
Consider an investor who purchases a townhouse in Frankston with rental income covering most of the loan repayment. They choose a variable rate loan with full offset, parking surplus cash in the offset account to reduce interest while keeping funds accessible for future purchases or property maintenance. The offset reduces taxable interest over time, and the variable structure allows them to refinance without break costs when a better product becomes available.
Repayment Type: Interest Only or Principal and Interest
Interest-only repayments keep your monthly outlay lower by deferring principal payments, usually for up to five years. Principal and interest repayments reduce the loan balance over time and build equity faster.
Investors targeting cash flow often select interest-only terms during the early years of ownership, particularly when holding multiple properties. The lower repayment frees up income for additional deposits or property upgrades. Once the interest-only period ends, the loan reverts to principal and interest unless you negotiate an extension. Lenders assess serviceability at principal and interest rates even when approving interest-only terms, so your borrowing capacity reflects the higher future repayment.

Offset Accounts and Redraw Facilities
An offset account is a transaction account linked to your loan. Every dollar in the offset reduces the balance on which interest is calculated, without limiting access to your funds.
Full offset accounts deliver the strongest tax outcome for investors because they reduce interest charges without creating a tax liability. Partial offset accounts apply only a portion of the balance against the loan. Redraw facilities let you withdraw extra repayments you have made, but accessing redraw can be slower and may involve conditions or fees. For investors managing cash across several properties, offset accounts provide clarity and control.
Loan to Value Ratio and Deposit Requirements
Lenders assess investment loans based on the LVR, which is the loan amount divided by the property value. Most lenders cap investor loans at 90 per cent LVR, with some requiring 80 per cent or lower depending on the applicant's income and existing debt.
An LVR above 80 per cent usually triggers Lenders Mortgage Insurance, which protects the lender but adds to your upfront cost. LMI is calculated on a sliding scale and is generally higher for investor loans than for owner-occupier lending. If you are using equity from an existing property to fund the deposit, the lender assesses the combined LVR across both securities. This calculation affects both your borrowing capacity and your ability to access investment loan options from banks and lenders across Australia.
Serviceability Assessment and Debt-to-Income Limits
Lenders assess your ability to service an investment loan at a rate at least 3 percentage points above the loan product rate. They also factor in rental income, applying a discount known as a shading or vacancy rate to account for periods without tenants.
From February this year, lenders have been required to limit new investor lending to borrowers with a debt-to-income ratio of six times or greater to no more than 20 per cent of their quarterly investor loan volume. If your total borrowings, including the new loan, exceed six times your gross income, you may fall within that restricted allocation. Not all lenders approach this limit in the same way, and working with a broker who understands each lender's current position improves your chance of approval at a competitive rate.
Portability, Split Loans, and Future Flexibility
Portability allows you to transfer your loan to a different property without refinancing. This feature matters when you plan to sell one investment property and purchase another, preserving your existing rate and terms.
Split loan structures let you divide your borrowing between variable and fixed rates, or between interest-only and principal and interest repayments. In our experience, investors with lumpy income or planned capital expenses value the flexibility of splitting a portion to variable while fixing another portion for budget certainty. Not all lenders offer portability or splits on investor products, so confirm availability during the comparison stage rather than at settlement.
Comparing Lender Policies on Rental Income and Property Type
Lenders vary in how they treat rental income and which property types they will finance. Some lenders accept 80 per cent of market rent when assessing serviceability, while others apply a lower percentage or require a lease in place before settlement.
Certain lenders restrict lending on apartments above a specified floor level, student accommodation, or properties in regional areas with declining populations. Others impose lower LVR limits on units in buildings with high investor concentration. When comparing loan options, check not only the rate and features but also whether the lender will finance the specific property you intend to purchase. A loan that suits a house in Doncaster may not be available for a studio apartment in a high-rise development.
Fees, Discharge Costs, and Ongoing Account Charges
Application fees, valuation fees, settlement fees, and annual account-keeping fees differ across lenders and products. Some lenders waive application fees during promotional periods, while others bundle costs into a single establishment charge.
Discharge fees apply when you pay out the loan or refinance to another lender. These typically range from a few hundred dollars to over $500 depending on the institution. Ongoing monthly or annual fees add up over the life of the loan, so factor them into your total cost comparison alongside the interest rate. A product with no ongoing fee and a rate 0.10 per cent higher may cost less over five years than a loan with a lower rate and a $395 annual fee.
Using a Broker to Compare Investment Loan Products
Brokers hold access to loan products from multiple lenders, including some that do not offer direct consumer applications. They compare rates, features, LVR policies, and serviceability approaches across the panel, then match those variables to your deposit size, income structure, and investment strategy.
In Victoria, investors often hold properties across metro and regional locations, use equity from owner-occupied homes to fund deposits, and manage trusts or company structures. Each of these variables affects which lenders will approve the loan and at what terms. A broker familiar with lender policy can identify which institutions assess rental income favourably, which allow higher LVRs on specific property types, and which offer rate discounts for borrowers with existing lending relationships. This knowledge reduces application time and improves your chance of securing the product that aligns with your portfolio goals.
Comparing investment loans requires attention to features, fees, lender policy, and how each product interacts with your current financial position. The loan that delivers the lowest cost and strongest flexibility depends on your deposit size, income type, property choice, and whether you plan to grow your portfolio or hold long term.

Frequently Asked Questions
What is the difference between variable and fixed rate investment loans?
Variable rates move with the market and usually include offset accounts and unlimited extra repayments. Fixed rates lock in your repayment for a set period but restrict additional repayments and typically do not offer offset functionality.
How does an offset account benefit property investors?
An offset account reduces the loan balance on which interest is calculated, lowering your interest charges without creating a tax liability. Every dollar in the offset works to reduce interest while remaining accessible for other uses.
What loan to value ratio do lenders allow on investment properties?
Most lenders cap investment loans at 90 per cent LVR, with some requiring 80 per cent or lower depending on your income and existing debt. An LVR above 80 per cent usually triggers Lenders Mortgage Insurance.
How do lenders assess rental income when approving an investment loan?
Lenders typically accept between 70 and 80 per cent of market rent when assessing serviceability, applying a discount to account for vacancy periods. Some lenders require a lease in place before settlement, while others use a rental appraisal.
Why do some lenders restrict lending on certain property types?
Lenders may impose lower LVR limits or decline lending on apartments above certain floor levels, student accommodation, or properties in areas with declining populations. These restrictions reflect the lender's risk assessment of the property type and location.
