An investment loan is structured differently from a home loan because lenders view rental properties as higher risk.
The interest rate is higher, the deposit requirement is steeper, and the way your income is assessed includes rental income but also factors in vacancy periods and property expenses. For Queensland buyers considering their first or next investment, understanding these differences before you apply will shape how much you can borrow and which loan features align with your strategy.
What Makes an Investment Loan Different from a Home Loan
Lenders price investor loans at a premium, typically between 0.30 and 0.60 percentage points above the equivalent owner-occupier rate. The deposit requirement is also higher. While a first home buyer may borrow up to 95 per cent of the property value, most lenders cap investor borrowing at 90 per cent and some require 80 per cent or less for properties in certain postcodes or for buyers with multiple mortgages already.
Serviceability is calculated with a three percentage point buffer above the product rate, and rental income is shaded by 20 per cent to account for vacancy and maintenance costs. If you earn a salary and plan to rely on rent to service the loan, lenders will include only 80 per cent of the expected rental income in their assessment. That shading can reduce your borrowing capacity by tens of thousands of dollars compared to what the numbers suggest on paper.
How Rental Income Is Assessed When You Apply
Lenders use a rental assessment based on either a signed lease or a valuer's opinion of market rent. If the property is tenanted at the time of application, the lease amount is used. If it is vacant or you are buying off the plan, the valuation will include a rental estimate and that figure, reduced by 20 per cent, becomes part of your income calculation.
Consider a buyer purchasing a two-bedroom unit in Fortitude Valley with an estimated rent of $600 per week. The lender will treat that as $480 per week of usable income when calculating serviceability. If your salary is $90,000 and you have $1,200 in monthly expenses, the rental income helps, but it does not replace a strong employment history or existing equity. Lenders still want to see that you can service the loan if the property sits vacant for a period.
Interest-Only Repayments and Why Investors Use Them
Interest-only repayments allow you to pay only the interest portion of the loan each month, leaving the principal balance unchanged. This lowers the monthly repayment and can improve cash flow, particularly in the early years when rental income may not cover all holding costs.
Most lenders offer interest-only periods of up to five years on investment loans, after which the loan reverts to principal and interest. The appeal is not just lower repayments but also the ability to redirect cash into other investments or offset accounts. If you hold multiple properties, keeping repayments low on one loan can free up serviceability to borrow for the next.
Interest-only is not suitable for every investor. If your goal is to pay down debt quickly or you are relying on capital growth in a market where values are flat, principal and interest repayments may be a more sustainable choice. The loan structure should match your time frame and risk tolerance, not just your current cash position.

Fixed or Variable Rates for Property Investment
Variable rate loans give you flexibility to make extra repayments, redraw funds, and access offset accounts without penalty. Fixed rate loans lock in your interest cost for a set period, usually between one and five years, but limit your ability to make lump sum repayments or exit the loan without incurring break costs.
Many investors split their loan between fixed and variable. A portion fixed provides certainty around repayments for budgeting, while the variable portion allows access to redraw and offset features. If you plan to use equity from the investment property to fund further purchases, a variable rate or split structure keeps that option open without triggering break fees.
Rate discounts on investor loans are typically smaller than those offered to owner-occupiers. A lender may offer a discount of 0.80 percentage points on an owner-occupier variable loan but only 0.50 percentage points on an investor loan with the same deposit and credit profile. Shop around, because discounts vary widely between lenders and some offer better pricing for investors with larger portfolios or higher deposits.
Equity Release and How It Funds Your Next Purchase
Equity is the portion of the property you own outright. If your investment property is worth $700,000 and you owe $500,000, you have $200,000 in equity. Lenders will allow you to borrow against that equity, typically up to 80 per cent of the property's value, to fund a deposit on your next purchase.
In practice, if the property is valued at $700,000 and you can borrow up to 80 per cent of that value, the maximum loan is $560,000. You already owe $500,000, so you can access $60,000 in usable equity. That amount can be used as a deposit, reducing the need to save additional cash and allowing you to move faster when the right opportunity appears.
Using equity to fund deposits is common among investors building a portfolio, but it increases your total debt and reduces your serviceability for future loans. Each time you release equity, your monthly repayments rise, and your ability to borrow again depends on whether your income can support the additional commitment. Speak to a broker before refinancing to release equity so the structure supports both your current property and your next move.
Lenders Mortgage Insurance and the 80 Per Cent Threshold
If you borrow more than 80 per cent of the property's value, most lenders will require you to pay Lenders Mortgage Insurance. LMI is a one-off premium that protects the lender if you default, and the cost can range from a few thousand dollars to over $30,000 depending on the loan amount and deposit size.
For investors, LMI is often capitalised into the loan rather than paid upfront. While this keeps cash free for other costs such as stamp duty and legal fees, it increases your loan balance and your ongoing repayments. Some lenders will not offer LMI on investor loans above 90 per cent, and others apply higher premiums or stricter serviceability tests once you cross the 80 per cent threshold.
If you can avoid LMI by increasing your deposit or using equity from another property, the saving is significant. A borrower with a 15 per cent deposit on a property valued at $650,000 will pay LMI, while a borrower with a 20 per cent deposit on the same property will not. That difference can be $15,000 or more, depending on the lender and loan structure.
Tax Changes from July 2027 and What They Mean for New Investors
From 1 July 2027, residential investment properties purchased after 7:30pm on 12 May 2026 will no longer allow net rental losses to be offset against salary or wage income unless the property is classified as an eligible new build. Losses from affected properties can only be offset against other residential rental income or carried forward to offset future rental income or capital gains.
Properties you already own, or those you had under contract before that date, are not affected. If you bought an established unit in New Farm in early 2026, you can continue to offset losses against your salary for as long as you own that property. If you buy an established townhouse in Bulimba in late 2026, you can offset losses until 30 June 2027, after which those losses are quarantined.
Eligible new builds retain full negative gearing. A new build is defined as a dwelling constructed on previously vacant land or a development that increases the total number of dwellings on the site. A knock-down rebuild that replaces one house with one house does not qualify. If you are considering new construction or a dual-occupancy project, confirm with your accountant whether the property meets the definition before you commit.
The capital gains tax discount is also changing from 1 July 2027. For properties purchased after 12 May 2026, the 50 per cent CGT discount will be replaced with cost base indexation and a minimum 30 per cent tax rate on real gains. Gains that accrued before 1 July 2027 on properties you already own will continue under the current rules. Eligible new builds will have the option to elect either the 50 per cent discount or indexation with the 30 per cent minimum rate, giving new build investors a choice depending on their holding period and inflation.
These changes do not prevent you from building wealth through property, but they do shift the economics. If you were planning to buy an established property with the expectation of offsetting rental losses against your income for ten years, you now need to model the investment assuming those losses are quarantined after June 2027. If you were comparing an established property to a new build, the tax treatment now favours the new build more heavily than it did before the legislation passed.
What Somerset Finance Looks at Before Recommending a Lender
Every lender has a different appetite for investor loans. Some will lend up to 90 per cent on units in Brisbane's CBD, others cap exposure at 80 per cent or apply postcode restrictions. Some lenders treat body corporate fees as a standard expense, others load them more heavily into the serviceability calculation. If you own multiple properties, some lenders will assess each one individually while others apply portfolio-level limits.
We compare loan products across the panel to match your deposit, income type, property location and goals. If you are buying in a regional area with limited rental comparables, we will approach lenders who rely on valuer estimates rather than requiring a signed lease. If you are refinancing to release equity, we will structure the split so you retain access to offset accounts and redraw on the portion of the loan you may need to access later.
The loan amount you can access depends on your income, existing debts, the rental income from the property, and the lender's policy at the time you apply. Serviceability can change between lenders by $100,000 or more on the same income and deposit. We run the numbers before you apply so you know what is achievable and which lender will support the structure you need for future growth.

Frequently Asked Questions
How much deposit do I need for an investment property loan in Queensland?
Most lenders require a minimum 10 per cent deposit for an investment loan, though some cap lending at 80 per cent to avoid Lenders Mortgage Insurance. A larger deposit improves your interest rate and borrowing capacity.
Can I use rental income to help me qualify for an investment loan?
Yes, lenders will include rental income in your serviceability assessment, but they reduce it by 20 per cent to account for vacancy and maintenance. You still need sufficient personal income to meet the lender's serviceability buffer.
What is negative gearing and how do the new tax rules affect it?
Negative gearing allows you to offset rental losses against your salary. From 1 July 2027, this is quarantined for established properties purchased after 12 May 2026, but eligible new builds retain full negative gearing.
Should I choose a fixed or variable rate for my investment loan?
Variable rates offer flexibility for extra repayments and access to offset accounts, while fixed rates lock in your interest cost. Many investors use a split structure to balance certainty with flexibility.
Can I use equity from my investment property to buy another one?
Yes, you can borrow against the equity in your investment property, typically up to 80 per cent of its value. The amount you can access depends on your current loan balance and serviceability for the additional debt.
