Compare the Cheapest Home Loan Options for Property Investors in Australia

Investing in property is a cornerstone of wealth creation for many Australians, but the key to maximizing returns often lies in minimizing costs—starting with your home loan. With interest rates and fees varying significantly across lenders, finding the cheapest home loan tailored for investors can save you tens of thousands of dollars over the life of the loan. This article provides a side-by-side comparison of the most affordable mortgage options available in 2025, highlighting not just the headline rates but the hidden costs and long-term savings that can make or break your investment strategy.

Understanding the Investor Mortgage Landscape in 2025

The Australian property market remains resilient, with investors continuing to play a significant role. According to the Australian Bureau of Statistics (ABS), investor lending commitments have shown steady growth through 2024, reflecting confidence in long-term capital gains and rental yields. However, the lending landscape has evolved. Lenders have tightened serviceability buffers, and the Reserve Bank of Australia (RBA) cash rate, which influences variable mortgage rates, has been relatively stable at 4.35% since late 2023, with potential cuts anticipated in late 2025. This environment makes it crucial for investors to scrutinize loan products beyond the advertised rate.

Investor loans typically come with higher interest rates than owner-occupier loans due to perceived higher risk, and many lenders impose additional fees or stricter loan-to-value ratio (LVR) requirements. However, competition among lenders—including online-only banks, credit unions, and non-bank lenders—has led to some highly competitive offers. Our comparison focuses on variable and fixed-rate options, highlighting products from both major banks and smaller institutions to give a comprehensive view.


Key Factors to Consider When Choosing an Investor Loan

Before diving into the comparison, it’s essential to understand what makes a loan truly cheap. The cheapest loan isn’t just the one with the lowest interest rate; it’s the one with the lowest total cost over the period you plan to hold the investment property. Key factors include:

• Interest Rate: The headline rate, whether variable or fixed, directly impacts your monthly repayments.
• Comparison Rate: This includes the interest rate plus most upfront and ongoing fees, giving a truer picture of the loan’s cost.
• Fees: Upfront fees (application, valuation, settlement) and ongoing fees (annual, monthly, redraw) can add up.
• Features: Offset accounts, redraw facilities, and the ability to make extra repayments can save you interest and provide flexibility.
• LVR Restrictions: Many investment loans require a minimum 20% deposit (80% LVR), though some lenders accept less with Lenders Mortgage Insurance (LMI).
• Loan Term: Most investors opt for interest-only (IO) periods to maximize tax deductions, but principal-and-interest (P&I) loans often have lower rates.

Hidden costs can include rate lock fees, discharge fees, or break costs on fixed loans. Always read the fine print.

Side-by-Side Comparison of Low-Rate Investor Loans

Below is a comparison of some of the cheapest investor home loans available in Australia as of early 2025. Rates are based on a $500,000 loan with an LVR of 80% (unless stated otherwise) and include both variable and fixed options. Data is sourced from official lender websites and financial comparison platforms like Moneysmart.gov.au.

Analysis of the Top Contenders

Unloan – The Rate Leader Unloan, backed by Commonwealth Bank, offers one of the lowest variable rates for investors at 6.29% p.a. with no fees whatsoever. The lack of an offset account may be a drawback for some investors who want to park cash to reduce interest, but the redraw facility is free and unlimited. Unloan also offers a unique loyalty discount: your rate decreases by 0.01% each year for up to 30 years. This can lead to significant long-term savings, making it arguably the cheapest option over time.

Tiimely Home – Tech-Savvy and Competitive Tiimely Home (formerly Tic:Toc) is another digital lender with a sharp rate of 6.34% p.a. and zero fees. Like Unloan, it lacks an offset account but provides a robust redraw facility. Tiimely’s platform uses automated credit assessment, which can speed up approval. The long-term cost is slightly higher than Unloan’s due to the lack of a loyalty discount, but it remains a top pick for tech-savvy investors.

Homestar Finance – Offset Included Homestar Finance offers a variable rate of 6.44% p.a. with a partial offset account—meaning you can offset a portion of your loan balance. This feature is rare at such a low rate and can be a game-changer for investors who hold significant cash reserves. The no-fee structure and redraw facility add to its appeal. While the rate is marginally higher than Unloan’s, the offset benefit could result in lower net interest costs depending on your cash flow.

Suncorp Fixed Rate – Stability in a Volatile Market For investors seeking certainty, Suncorp’s 2-year fixed rate at 6.59% p.a. is competitive. Fixed rates protect against potential RBA rate hikes, though economists predict stability or cuts. The comparison rate of 6.78% reflects the revert rate after the fixed period, so it’s crucial to refinance or renegotiate before the term ends. Suncorp often waives upfront fees for new customers, but check for break costs if you exit early.

ME Bank and ING – Feature-Rich Alternatives ME Bank (6.49% p.a.) and ING (6.54% p.a.) offer full offset accounts and zero ongoing fees, making them strong contenders for investors who prioritize flexibility. ME Bank is member-owned, which can mean better customer service, while ING’s Orange Advantage package includes a range of perks like no ATM fees globally. These loans are slightly more expensive than Unloan but may be worth it for the offset feature.

Hidden Costs That Can Erode Your Savings

Even the cheapest loan can become expensive if you overlook hidden costs. Here are the most common traps for investors:

• Application and Settlement Fees: While many lenders advertise $0 upfront fees, some still charge for legal or valuation costs. For example, a $500 valuation fee might seem small but adds to your initial outlay.
• Rate Lock Fees: If you opt for a fixed rate, lenders may charge a rate lock fee (usually 0.15% of the loan amount) to guarantee the rate before settlement. On a $500,000 loan, that’s $750.
• Break Costs on Fixed Loans: Exiting a fixed-rate loan early can incur break costs that run into thousands of dollars, especially if interest rates have fallen. Always check the formula used by the lender.
• LMI Costs: If you borrow more than 80% LVR, you’ll pay Lenders Mortgage Insurance, which can be a one-off cost of $10,000 or more. Some lenders capitalize this into the loan, increasing your repayments and interest.
• Offset Account Fees: Some lenders offer offset accounts only with package loans that carry annual fees (e.g., $395 p.a.). Always calculate whether the interest saved exceeds the fee.
• Discharge Fees: When you refinance or sell, lenders may charge a discharge fee (typically $350–$500). While not huge, it’s an avoidable cost with some lenders.

To illustrate long-term savings, consider a $500,000 investment loan over 30 years. A 0.20% difference in interest rate (e.g., 6.29% vs. 6.49%) can save over $20,000 in interest over the life of the loan, assuming P&I repayments. Add in fee savings, and the cheapest loan becomes a clear winner.


Long-Term Savings Strategies for Investors

Choosing the right loan is just the first step. To maximize long-term savings:

1. Use an Offset Account Wisely: If your loan has an offset, keep all rental income and personal savings in it to reduce the interest charged. Even a partial offset can save thousands.
2. Refinance Regularly: Lenders often reserve their best rates for new customers. Review your loan every two years and consider refinancing if a better deal exists. Just weigh the costs of switching.
3. Opt for Interest-Only Periods Strategically: IO loans reduce your monthly repayments, freeing up cash for other investments. However, they cost more in interest over time. Use IO periods during the early years of investment and switch to P&I later.
4. Make Extra Repayments When Possible: If your loan has a redraw facility, any extra repayments reduce the principal and thus the interest. This is especially powerful in the early years of the loan.
5. Negotiate with Your Lender: Don’t accept the advertised rate. Call your lender and ask for a discount. Having a competing offer in hand can help.

The Role of a Mortgage Broker

Navigating the maze of investor loans can be daunting. A good mortgage broker can help you find the cheapest loan tailored to your circumstances. They have access to a wide panel of lenders and can negotiate on your behalf. The Australian Securities and Investments Commission (ASIC) regulates brokers, and they must act in your best interest. Best of all, most brokers don’t charge you directly—they receive a commission from the lender.

When choosing a broker, look for one accredited with the Mortgage & Finance Association of Australia (MFAA) or the Finance Brokers Association of Australia (FBAA). Ensure they explain all fees and commissions upfront.

Current Trends and Future Outlook

The RBA’s cash rate decisions will heavily influence investor loan rates in the coming years. As of mid-2025, many economists predict a rate cut by year-end, which would reduce variable rates. However, global economic uncertainties mean fixed rates could remain attractive. The Australian government’s Housing Australia Future Fund and various state-based incentives for build-to-rent projects may also impact investor demand and lending criteria.

Digital lenders like Unloan and Tiimely are disrupting the market by offering ultra-low rates with no fees, forcing traditional banks to compete. This trend is likely to continue, benefiting investors who are willing to forgo branch access for cost savings.

FAQ

What is the difference between a comparison rate and an interest rate?

The interest rate is the annual cost of borrowing the principal, expressed as a percentage. The comparison rate includes the interest rate plus most fees and charges, giving a more accurate picture of the total cost. Always compare loans using the comparison rate, not just the headline rate.

Can I get an investment loan with less than a 20% deposit?

Yes, but you will likely need to pay Lenders Mortgage Insurance (LMI). Some lenders offer low-deposit investment loans with LMI capitalized into the loan, but the interest rate may be higher. First-time investors might also explore family guarantee loans.

Is it better to choose a fixed or variable rate for an investment property?

It depends on your risk tolerance and market outlook. Fixed rates offer certainty, which is helpful for budgeting, but you may miss out if variable rates fall. Variable rates are often lower initially and offer more flexibility (e.g., extra repayments). Many investors split their loan, fixing a portion and keeping the rest variable.

How often should I review my investment loan?

At least once a year, or whenever there’s a significant change in interest rates. Refinancing every 2–3 years can ensure you’re always on a competitive rate, but consider the costs of switching.
