Comparing investment loans means looking beyond the advertised rate to understand how loan features align with your property strategy and cash flow needs.
Most Queensland investors start their comparison by checking what rate each lender is offering. That matters, but the structure you choose, the fees attached, and whether you can access equity later often have a bigger impact on your portfolio growth than a 0.10% rate difference. If you're looking at multiple properties over time, the right loan comparison focuses on flexibility as much as cost.
Interest Only or Principal and Interest: What Fits Your Cash Flow
Interest only loans reduce your monthly repayments by deferring principal repayments for a set period, usually up to five years. Principal and interest loans build equity from day one but require higher repayments.
Consider an investor purchasing a unit in Maroochydore as a long-term hold. They choose interest only for the first five years to keep repayments lower while the property appreciates. Rental income covers most of the loan cost, and they reinvest the cash flow difference into renovations that lift the property's value. At the end of the interest only period, they refinance and reassess whether to continue interest only or switch to principal and interest based on their portfolio position at that time.
The choice depends on whether you're prioritising cash flow now or equity growth over time. Interest only works well when you're building a portfolio and need flexibility. Principal and interest suits investors who want to reduce debt over time or are closer to financial independence.
Fixed Rate or Variable Rate: Matching Certainty to Strategy
Variable rates move with the market and usually come with offset accounts and redraw facilities. Fixed rates lock in your repayments for one to five years but limit your ability to make extra repayments or access features like offset accounts.
In our experience, investors who plan to hold a property for decades often prefer variable rates because they value the flexibility to make extra repayments when cash flow allows. Investors with tighter margins or multiple properties sometimes fix a portion of their loan to manage repayment certainty while keeping part of the loan variable for flexibility.
Some lenders let you split your loan between fixed and variable, which gives you partial rate protection without losing access to offset accounts entirely. If you're comparing loan products, check whether the lender allows splits and whether there's a fee to set that up.
Loan Features That Support Portfolio Growth
Offset accounts, redraw facilities, and the ability to release equity matter more as your portfolio grows.
An offset account links to your loan and reduces the interest you pay based on the balance you hold in the account. If you have a loan amount of $500,000 and $30,000 sitting in an offset account, you only pay interest on $470,000. That saves you interest without locking funds away, which is useful if you're saving for your next deposit or keeping cash on hand for property expenses.
Redraw facilities let you access extra repayments you've made, but some lenders limit how much you can redraw or charge a fee each time. If you're planning to use your loan as a revolving line of credit for future purchases, check the redraw terms carefully.
Equity release is another feature worth comparing. As your property increases in value, you may want to borrow against that equity to fund your next purchase. Some lenders make this process straightforward with a simple top-up. Others require a full refinance, which can delay your plans and add costs. If portfolio growth is part of your strategy, ask how each lender handles equity access before you commit.

Fees and Loan to Value Ratio: The Hidden Cost Factors
Application fees, valuation fees, ongoing account fees, and discharge fees vary widely between lenders. Some lenders waive application fees but charge higher ongoing fees. Others have no ongoing fees but charge more upfront.
Your loan to value ratio also affects your cost. If you're borrowing more than 80% of the property's value, you'll usually pay Lenders Mortgage Insurance. LMI protects the lender if you default, and the premium can add thousands to your upfront costs. Increasing your deposit to 20% or more removes that cost entirely, which makes a significant difference to your overall borrowing expense.
Some lenders also adjust their interest rate based on your LVR. A loan at 70% LVR might attract a lower rate than the same loan at 85% LVR, even from the same lender. If you're comparing loan options, ask for a rate based on your actual deposit amount rather than relying on the advertised rate.
Rate Discounts and Investor Interest Rates
Investor interest rates are typically higher than owner-occupier rates, but the gap varies by lender. Some lenders price investor loans only 0.20% to 0.30% above owner-occupier rates. Others charge 0.50% or more.
Rate discounts are often negotiable, especially if you have a strong borrowing position or are bringing multiple loans to the same lender. Package discounts, professional discounts, and loyalty discounts can reduce your rate, but they're not always advertised upfront. A broker can often secure a better rate than the standard offering, particularly if you're refinancing or consolidating multiple properties under one lender.
If you're comparing lenders yourself, ask each one what discounts apply to your situation. Don't assume the advertised rate is the rate you'll actually pay.
How Recent Budget Changes Affect Your Loan Comparison
From 1 July 2027, negative gearing and capital gains tax treatment will change for established residential properties purchased after 12 May 2026. If you bought before that date, your existing arrangements continue. If you're buying from 13 May 2026 onwards, rental losses on established properties will only be deductible against property income, not your salary or wages. New builds remain exempt from these changes.
This affects your loan comparison because the after-tax cost of holding an investment property will increase for established properties purchased after Budget night. If you're comparing properties rather than just loans, new builds now carry a tax advantage that makes them more appealing from a cash flow perspective. Your loan structure should reflect that. For example, maximising deductions through loan structuring becomes less valuable on established properties purchased after May 2026, which shifts the focus back to rate and flexibility.
If you're unsure how the new rules apply to your situation, speak with a tax adviser before finalising your loan choice. The loan structure that suited investors 12 months ago may not suit your circumstances now.
Refinancing and Accessing Investment Loan Options Across Lenders
If your current loan no longer suits your strategy, refinancing lets you switch to a loan product with features that align with where your portfolio is now. Investors refinance for several reasons: to access a lower rate, to release equity, to consolidate multiple loans, or to switch from principal and interest to interest only.
Refinancing costs include application fees, valuation fees, and sometimes discharge fees from your existing lender. Some lenders offer cashback incentives or cover your switching costs, which can offset those expenses. If you're comparing refinance options, calculate the total cost of switching and compare it to the benefit you'll gain over the next two to three years.
Working with a broker gives you access to investment loan options from lenders across Queensland and nationally, including lenders that don't deal directly with the public. If you're comparing loans on your own, you're limited to the lenders you know about and the rates they advertise. A broker can show you the full range and explain which features suit your strategy.
For investors holding multiple properties, a loan health check every couple of years ensures your loans still suit your goals. Rates change, lenders change their credit policies, and your own financial position changes. A loan that worked well when you bought may no longer be the right fit.
Call one of our team or book an appointment at a time that works for you to compare your current loan against what's available now and make sure your investment property finance is structured to support your long-term goals.
Frequently Asked Questions
Should I choose interest only or principal and interest for my investment loan?
Interest only loans reduce your monthly repayments by deferring principal repayments, which improves cash flow and is useful for portfolio growth. Principal and interest loans build equity from day one and suit investors focused on reducing debt over time.
What loan features matter most for property investors?
Offset accounts, redraw facilities, and the ability to release equity are the most important features for portfolio growth. These features give you flexibility to manage cash flow, access savings, and borrow against equity for future purchases.
How do the recent Budget changes affect investment loan comparisons?
From 1 July 2027, negative gearing on established properties purchased after 12 May 2026 will only be deductible against property income, not wages. New builds remain exempt, which shifts the focus to rate and flexibility when comparing loans for established properties.
What is the difference between investor and owner-occupier interest rates?
Investor interest rates are typically 0.20% to 0.50% higher than owner-occupier rates, depending on the lender. The gap varies, and rate discounts are often negotiable based on your borrowing position and the number of loans you're bringing to the lender.
When should I refinance my investment loan?
Refinancing makes sense when you want to access a lower rate, release equity, consolidate loans, or switch repayment structures. A loan health check every couple of years helps ensure your loan still suits your portfolio strategy.
