Investment loan features aren't just add-ons. They're tools that affect how much you pay, what you can claim, and how quickly you can grow your portfolio.
Offset Accounts and How They Work for Investors
An offset account links to your investment loan and reduces the interest you're charged based on the balance you hold in that account. Unlike an owner-occupied loan where an offset account saves you money you'd otherwise spend on interest, an investment loan offset account reduces your deductible interest, which can sometimes work against you at tax time.
Consider a buyer who holds a property in Craigieburn with a loan balance of $450,000 at a variable rate. They keep $30,000 in an offset account. Instead of paying interest on the full $450,000, they're charged interest on $420,000. That sounds helpful, but it also means they're claiming less interest as a tax deduction. If that $30,000 is genuinely spare cash with no better use, the offset still delivers a net benefit. But if it could be working harder elsewhere, such as funding another deposit or sitting in a higher-yield account, the trade-off changes.
In our experience, offset accounts suit investors who want flexibility without locking funds into the loan itself. They're useful when you're building a deposit for the next property or keeping cash aside for unexpected repairs. They're less useful when you're trying to maximise tax deductions at every opportunity.
Interest-Only Repayments and Cashflow Management
Interest-only repayments let you pay only the interest portion of the loan for a set period, usually between one and five years. The loan balance doesn't reduce, but your monthly repayment is lower, which can help with cashflow if rental income doesn't fully cover your costs.
This feature suits investors focused on building a portfolio rather than paying down individual loans. Lower repayments mean more capital available for the next deposit or to cover holding costs during periods of vacancy. After the interest-only period ends, the loan typically reverts to principal and interest repayments, which will be higher because you're now paying off the balance over a shorter remaining term.
A buyer holding two properties in Werribee and Tarneit might choose interest-only terms on both loans to free up monthly cashflow. If one property sits vacant for six weeks, the reduced repayment obligation makes that gap more manageable. Once both properties are tenanted and income is stable, they can either extend the interest-only period or switch to principal and interest and start reducing the debt.

Interest-only periods aren't automatically renewed. You'll need to reapply, and lenders reassess your income, debt levels, and property values before approving an extension. If your circumstances have changed or property values have dropped, you may be moved to principal and interest repayments whether you're ready or not.
Redraw Facilities and Why They're Different to Offset Accounts
A redraw facility lets you access extra repayments you've made above the minimum required amount. If you're on a principal and interest loan and pay more than you need to, that extra amount sits in the loan and you can withdraw it later if needed.
The difference between redraw and offset matters for tax purposes. Money in an offset account isn't part of the loan, so withdrawing it doesn't change your deductible interest. Money in redraw has already reduced your loan balance, so pulling it back out can complicate your tax position, especially if you use it for non-investment purposes.
Redraw works well if you're disciplined about keeping investment funds separate and only withdrawing for investment-related costs. It's less useful if you're regularly dipping into it for personal expenses, because tracking the deductible portion of your interest becomes messy.
Fixed Rate Options and When They Suit Investors
A fixed rate locks in your interest rate for a set period, usually between one and five years. Your repayments stay the same regardless of what happens to variable rates, which makes budgeting more predictable.
Fixed rates often come with restrictions. You might not be able to make extra repayments beyond a small annual limit, and you usually can't access an offset account or redraw facility during the fixed period. If you want to refinance your investment loan or sell the property before the fixed term ends, you may face break costs.
Fixed rates suit investors who want certainty and aren't planning to make extra repayments or adjust their loan structure in the short term. They're less useful if you're building a portfolio quickly and need flexibility to access equity or restructure loans as you grow.
Some investors split their loan between fixed and variable, which gives them partial rate protection while keeping some flexibility. That approach works if you're not sure which direction rates are heading and want to hedge your position.
Loan Portability and Moving Between Properties
Loan portability lets you transfer your existing loan to a different property without refinancing or paying discharge fees. If you sell one investment property and buy another, you can move the loan across instead of closing it and starting from scratch.
This feature is useful if you're upgrading within your portfolio or consolidating multiple properties into one. It saves on application fees, valuation costs, and the time it takes to process a new loan. Not all lenders offer portability, and those that do may still reassess your circumstances before approving the transfer.
Portability is less common with investment loans than with owner-occupied loans, so it's worth checking whether your lender includes it before you commit.
Equity Access and How It Supports Portfolio Growth
Equity access refers to your ability to borrow against the value of a property you already own. If your property has increased in value or you've paid down the loan, you may be able to release some of that equity to fund the deposit on another investment property.
Lenders typically let you borrow up to 80% of a property's value without paying Lenders Mortgage Insurance. If your property is worth $600,000 and you owe $400,000, you have $200,000 in equity. At 80% LVR, you could borrow up to $480,000 total, which means you could access up to $80,000 in usable equity for your next deposit.
Accessing equity doesn't require you to sell the property or disrupt your tenancy. It does increase your overall debt, so you'll need to show the lender that your income can service the higher loan amount. This is where rental income from your existing property helps, especially if it's been tenanted for more than six months and you can show a leasing history.
Equity release is one of the most powerful tools for building a property portfolio, but it only works if your properties are performing and your income supports the additional borrowing.
Loan Structure and Splitting Across Multiple Properties
Loan structure refers to how your borrowing is divided across different loans or splits. Some investors hold each property on a separate loan. Others combine multiple properties under one facility with internal splits for each asset.
Separate loans give you more control. If you want to sell one property, you can discharge that loan without affecting the others. If you want to fix the rate on one property and keep another variable, separate loans make that straightforward.
A single facility with multiple splits can reduce ongoing fees, because you're only maintaining one loan account. But it can also limit your flexibility if you want to refinance or restructure individual properties later.
We regularly see investors who started with a single facility and later wished they'd kept loans separate when they wanted to sell one property or switch lenders for part of their portfolio. The structure you choose upfront affects your options down the line, so it's worth thinking a few steps ahead.
Repayment Flexibility and Extra Repayment Limits
Repayment flexibility refers to how much control you have over when and how much you repay. Variable rate loans usually let you make unlimited extra repayments without penalty. Fixed rate loans often cap extra repayments at a set amount per year, such as $10,000 or $20,000.
For investors, repayment flexibility matters less than it does for owner-occupiers. You're usually trying to minimise repayments and maximise deductions, not pay the loan down faster. But if your strategy involves building equity quickly or preparing to access funds for the next purchase, having the option to make extra repayments without penalty can be useful.
Some lenders also let you switch between interest-only and principal and interest repayments during the loan term without refinancing. That flexibility can help if your circumstances change or your strategy shifts from growth to debt reduction.
Package Discounts and Fee Waivers
Many lenders offer loan packages that bundle your investment loan with other products, such as a transaction account or credit card, in exchange for a discounted interest rate and waived fees. The annual package fee is usually between $300 and $400, but the rate discount can be worth 0.20% to 0.50% per year, which adds up over time.
Package discounts make sense if the rate saving exceeds the package fee. On a $500,000 loan, a 0.30% discount saves you $1,500 per year, minus the $395 package fee, which still leaves you ahead by over $1,000.
Some packages also waive ongoing fees such as valuation fees, settlement fees, or discharge fees, which can be useful if you're refinancing or restructuring loans regularly as your portfolio grows.
Not all lenders offer the same package benefits, and not all investors qualify for the full discount. Your rate depends on your deposit size, loan amount, and credit profile, so the advertised package rate isn't always the rate you'll receive.
Application Process and What Lenders Assess for Investment Loans
When you apply for an investment loan, lenders assess your income, existing debts, living expenses, and the rental income the property is expected to generate. They don't count 100% of the rental income, they typically apply a shading rate of around 80%, which means they assume the property will be vacant for part of the year.
Lenders also assess your borrowing capacity using a buffer rate, usually 3% above the actual interest rate. Even if the loan rate is 6.00%, they'll test whether you can afford repayments at 9.00%. This buffer protects both you and the lender if rates rise.
You'll need to provide payslips, tax returns, and rental appraisals or leasing agreements. If you're self-employed, lenders typically want two years of financials. If the property is already tenanted, a signed lease strengthens your application because it shows confirmed income rather than an estimate.
Some lenders are more flexible with high loan-to-value ratios or allow you to use rental income from multiple properties to support a new purchase. Others cap the number of investment properties they'll lend against or apply stricter serviceability tests once you hold more than three or four properties.
Every lender has a different appetite for property investors, which is why working with a broker who knows which lenders suit your situation can make a real difference to how much you can borrow and what features you can access.

Frequently Asked Questions
What is the difference between an offset account and a redraw facility on an investment loan?
An offset account sits separately from your loan and reduces the interest charged without reducing your loan balance, while a redraw facility lets you access extra repayments you've made into the loan itself. Offset accounts are usually simpler for tax purposes because the money hasn't been applied to the loan.
Should I choose interest-only or principal and interest repayments for an investment loan?
Interest-only repayments suit investors focused on cashflow and portfolio growth, as they keep monthly costs lower and free up capital for other investments. Principal and interest repayments reduce your debt over time and can be useful once your portfolio is established and you want to build equity.
Can I access equity in my investment property to buy another property?
Yes, if your property has increased in value or you've paid down the loan, you can borrow against that equity to fund a deposit on another property. Lenders typically allow you to borrow up to 80% of the property's value without paying Lenders Mortgage Insurance.
Do fixed rate investment loans allow extra repayments?
Most fixed rate loans limit extra repayments to a set amount per year, often around $10,000 to $20,000. Exceeding that limit may trigger break costs, so fixed rates suit investors who aren't planning to make large extra repayments during the fixed period.
How do lenders assess rental income when I apply for an investment loan?
Lenders typically apply a shading rate of around 80% to the rental income, meaning they assume the property will be vacant for part of the year. If you have a signed lease, that strengthens your application by showing confirmed income rather than an estimate.
