Not every feature in an investment loan package is worth paying for.
The feature set that suits an investor buying their first rental property in Highton with a long hold strategy will look different to someone planning to refinance after three years or leverage equity for a second purchase. Choosing loan features means matching them to what you plan to do with the property, not what the product comparison sheet lists as available.
Interest-only repayments and how they affect cash flow
Interest-only repayments mean you pay only the interest portion each month and the loan balance does not reduce. Most lenders offer interest-only periods of one to five years on investment loans, after which the loan reverts to principal and interest.
Consider a buyer who purchases a two-bedroom unit in Highton near Reservoir Road as a rental property. At the time of writing, a one-bedroom unit in Highton rents for around $350 per week and a two-bedroom for around $450. If the loan is $500,000 at a variable rate, interest-only repayments sit around $2,300 per month, while principal and interest would be closer to $3,100. The difference frees up roughly $800 each month, which can be redirected to an offset account, put toward a second deposit, or used to manage periods between tenants.
The tax treatment does not change. Interest is claimable whether you pay principal or not. The choice is about timing and how you want to deploy surplus income. Investors who plan to sell or refinance within five years often favour interest-only because it keeps the loan balance intact and maximises the deduction. Those building equity for future borrowing may prefer principal and interest once cash flow permits.
Offset accounts and redraw on investment loans
An offset account is a transaction account linked to your loan. Every dollar in the account reduces the balance on which interest is calculated. If you have a $500,000 loan and $20,000 in offset, you pay interest on $480,000.
Redraw lets you access extra repayments you have made above the minimum. Both tools reduce interest, but the tax outcome differs. Money sitting in an offset account remains separate from the loan and can be withdrawn without affecting the deductible debt. Money paid into the loan and redrawn can blur the line between investment and private use, and if you redraw for a non-investment purpose, part of your interest may no longer be claimable.
In our experience, investors with plans to use surplus funds for renovations, a second property deposit, or personal expenses should prioritise an offset over redraw. Some lenders charge a monthly fee for offset accounts on investor loans, others include it. The cost is often $10 to $15 per month, which is justified if you regularly hold a balance above a few thousand dollars.

Fixed versus variable rates and prepayment flexibility
A variable rate moves with the lender's pricing decisions and lets you make extra repayments without penalty. A fixed rate locks in the interest cost for one to five years but limits extra repayments to a set amount each year, usually $10,000 to $30,000 depending on the lender.
The decision depends on your cash flow predictability and whether you want to park surplus income in the loan. Variable rates suit investors who expect irregular income, bonuses, or equity release from another property and want the option to reduce the loan balance or offset account at any time. Fixed rates suit those who want certainty over the interest deduction and do not plan to pay down the loan during the fixed period.
Some lenders allow a split structure, where part of the loan is fixed and part is variable. A common arrangement is 50:50, which gives rate stability on half the debt and full flexibility on the other half. The application is slightly more complex because the lender treats each portion as a separate loan facility, but there is no rule preventing you from holding both.
Portability and how it works when you sell and buy again
Portability means you can transfer the loan from one security property to another without discharging and reapplying. If you sell your Highton rental and buy another investment property at the same time, a portable loan lets you move the debt across, often with no exit or application fee.
Not all lenders offer portability, and those that do attach conditions. The new property must be acceptable security, the loan amount usually cannot increase beyond a small margin, and settlement dates need to align within a set window, commonly 30 to 90 days. If the new property is worth more and you need to borrow extra, the lender will treat the top-up as a new loan, which means a fresh serviceability assessment under current policy.
Portability is particularly relevant under the new negative gearing rules that apply from 1 July 2027. If you sell a property acquired before the 12 May 2026 announcement and buy a replacement that is not a qualifying new build, the replacement property will be subject to loss quarantining. A portable loan does not change that tax outcome, but it does reduce the transaction friction and cost when moving between properties.
Additional repayments, loan splits, and tax record keeping
Any feature that changes how money moves in and out of your loan affects the records you need to keep for your tax return. If you make additional repayments into a variable investment loan and later redraw those funds for private use, the interest on the redrawn portion is not claimable. The ATO expects you to maintain clear records showing the purpose of each drawdown.
This is why many accountants recommend keeping investment borrowings separate from private debt and using offset accounts rather than redraw where possible. If your loan structure includes multiple splits, such as a fixed portion and a variable portion, or a loan for the original purchase and a separate top-up for renovations, each split should have its own offset or repayment record.
Loan features do not replace good record keeping, but choosing features that align with how you plan to use the loan reduces the chance of a tax issue later. If you expect to access funds for non-investment purposes, structure the loan so that access is clean and documented from the outset. A refinance is one opportunity to reset the structure if your current loan has become tangled over time.
How the new tax rules affect feature selection
From 1 July 2027, rental losses on most residential investment properties acquired after 12 May 2026 can only be offset against other residential rental income or carried forward. Interest remains claimable, but the loss cannot reduce your salary or business income in the same financial year.
If you are purchasing a property in Highton now and plan to hold it as a rental, the loss quarantine will apply unless the property qualifies as a new build under the definition in the Act. The change does not reduce the value of interest deductions, but it does delay when you receive the tax benefit. In that context, features that improve cash flow, such as interest-only repayments, become more important because you cannot rely on a tax refund from negatively geared losses to smooth your position each year.
Investors building a portfolio may also want features that support equity release and future borrowing, such as offset accounts that preserve the loan balance and redraw facilities that allow access to built-up equity without a formal refinance. These features do not avoid the new rules, but they give you more control over timing and how you structure the next purchase.
The choice of loan features should reflect the tax treatment you expect over the hold period, not just the rate or headline comparison. If you are uncertain how the new rules apply to a property you are considering, seek advice from a licensed tax specialist before signing a contract. Once the property is acquired, the tax treatment is locked in.

Frequently Asked Questions
What is the difference between an offset account and redraw on an investment loan?
An offset account is a separate transaction account that reduces the loan balance on which interest is calculated. Redraw lets you access extra repayments made into the loan. Money in offset remains separate and can be withdrawn without affecting your tax deduction, while redraw can blur the line between investment and private use if withdrawn for non-investment purposes.
Do interest-only repayments reduce my tax deduction?
No. Interest is claimable whether you pay principal or not. Interest-only repayments reduce your monthly outgoing and preserve the loan balance, which can be useful for cash flow or future equity access, but the tax treatment of the interest does not change.
Can I transfer my investment loan to a new property without reapplying?
Some lenders offer portability, which lets you transfer the loan from one security property to another without discharging and reapplying. Conditions apply, including acceptable security, settlement timing, and loan amount limits. Not all lenders offer this feature.
How do the new negative gearing rules affect which loan features I should choose?
From 1 July 2027, rental losses on most properties acquired after 12 May 2026 can only be offset against residential rental income or carried forward. Features that improve cash flow, such as interest-only repayments and offset accounts, become more important because you cannot rely on a tax refund from negatively geared losses to smooth your position each year.
Should I choose a fixed or variable rate for an investment loan?
Variable rates allow unlimited extra repayments and suit investors with irregular income or plans to reduce the loan quickly. Fixed rates lock in the interest cost but limit extra repayments, usually to $10,000 to $30,000 per year. A split structure can provide both rate certainty and flexibility.
