The Pros and Cons of Investment Loan Features

An investment loan is the finance you arrange to purchase property you intend to rent out rather than live in. The features built into that loan determine how you repay it, what you can access later, and how the numbers work when tax time arrives.

Interest Only Repayments: Lower Monthly Costs with a Trade-Off

Interest only means you pay only the interest charged each month, without reducing the amount you originally borrowed. Your monthly repayment is lower compared to a principal and interest loan, which can improve cashflow if rent doesn't quite cover all your costs.

Consider a buyer who borrows to purchase a unit in Lalor, where vacancy rates remain relatively low due to steady rental demand from families and commuters working in Melbourne's northern corridor. With interest only repayments, the investor keeps more cash available each month to cover periods when the property sits vacant or needs maintenance. The offset is that the amount owing stays the same for the interest only period, which is typically one to five years. After that, the loan converts to principal and interest unless you renegotiate.

From 1 July 2027, new negative gearing rules take effect. If you purchase an established dwelling in Lalor on or after 7:30pm AEST on 12 May 2026, any rental loss can only be offset against other residential rental income or carried forward. It cannot reduce your salary or wage income. Properties purchased before that date and time, or contracts exchanged before that date and time awaiting settlement, retain full negative gearing under existing rules. Interest only structures don't change that quarantine, but they do influence how much interest you claim.

Offset Accounts: Reducing Interest Without Locking Funds Away

An offset account is a transaction account linked to your loan. The balance in the offset reduces the amount of interest calculated each month. If you owe $400,000 and hold $20,000 in a full offset, you pay interest on $380,000.

Offset accounts suit investors who want to reduce the interest they pay while keeping funds accessible. Money held in the offset can be withdrawn at any time for another deposit, urgent repairs, or any other purpose. Unlike an extra repayment into the loan itself, which may be difficult to redraw if your loan is interest only or if the lender applies redraw restrictions, the offset gives you control.

Not every lender offers offset accounts on investment loans, and those that do often charge a slightly higher interest rate or annual fee for the feature. The calculation depends on how much you expect to hold in the account and for how long. If you typically keep the account near zero, the feature costs more than it saves.

Fixed Rate Periods: Certainty Now, Less Flexibility Later

A fixed rate locks your interest rate for a set period, typically one to five years. Your repayment stays the same regardless of what happens to variable rates during that time.

Fixed rates appeal to investors who want predictable costs, particularly if rental income is tight and a rate rise would turn a small loss into a larger one. Lalor's rental market has remained stable, but an investor purchasing a three-bedroom house near the Lalor Plaza precinct might fix part of the loan to protect against rate increases while the property establishes a tenant history.

The limitation is that most fixed rate products restrict extra repayments to a small annual amount, often $10,000 or $20,000. Breaking a fixed loan early to sell, refinance, or pay down the balance can trigger break costs, which depend on the difference between your fixed rate and the lender's current cost of funds. Fixed rates also rarely come with offset accounts.

Some investors split their loan, fixing part and leaving part variable. That approach balances certainty with access to features like offset and unlimited extra repayments on the variable portion. You can read more about investment loans and the way different structures combine.

Redraw Facilities: Accessing Extra Repayments When You Need Them

A redraw facility lets you withdraw extra repayments you've made above the minimum required. If your monthly repayment is $2,000 and you pay $2,500, the additional $500 becomes available to redraw, subject to the lender's terms.

Redraw suits investors who make irregular lump sum payments when cashflow allows and want the option to retrieve that money later. The difference between redraw and offset is that redraw applies to funds you've already paid into the loan, while offset applies to funds held separately.

Some lenders restrict redraw on interest only loans because you're not required to pay down the balance, so there's no extra repayment to access. Others allow redraw but impose conditions, such as minimum redraw amounts, processing times, or fees. Always confirm the terms before relying on redraw as part of your strategy.

Portable Loans: Keeping Your Loan When You Sell and Buy Again

Portability lets you transfer your existing loan to a new property without discharging and reapplying. If you sell one investment property and purchase another, you can move the loan across, subject to the lender's approval of the new security.

This feature is useful when you want to sell and reinvest quickly without losing a low interest rate or paying discharge and establishment fees twice. Not all lenders offer portability, and those that do usually require the new property to meet their standard lending criteria. If the new property is worth significantly less or located in an area the lender considers higher risk, portability may not be approved.

Lalor sits within the City of Whittlesea, where residential development has increased housing stock over the past decade. Investors moving between properties in the northern growth corridor sometimes use portability to maintain loan continuity when upgrading from a unit to a house or consolidating two smaller holdings into one larger property.

Building Wealth Through the Right Loan Structure

The features you choose should match what you plan to do with the property and how you manage money. Interest only suits investors prioritising cashflow or holding property for capital growth without paying down debt. Offset suits those who accumulate savings and want flexibility. Fixed rates suit those who need cost certainty. Redraw suits those making irregular extra payments. Portability suits those planning to turn over properties within a portfolio.

Lalor's proximity to employment hubs like Epping, Thomastown, and the broader northern industrial corridor supports consistent rental demand, which makes it a location where investors often hold property long term. Long holds favour features like offset and variable rates that support flexibility over decades, rather than fixed terms that expire and require renegotiation every few years. If your strategy involves purchasing an investment property while you're still renting elsewhere, the loan structure needs to account for serviceability across both your rent and the investment loan repayment. You can explore that scenario further on the page about buying your first investment property.

No loan feature is inherently good or bad. Each one trades cost for flexibility, certainty for access, or immediate cashflow for long-term debt reduction. The structure that works is the one that aligns with your income pattern, your plans for the property, and the way you prefer to hold money.
