How to Secure an Investment Loan Pre-Approval in Brisbane

A pre-approval tells you how much a lender is likely to let you borrow before you commit to a property. For a Brisbane investor, it sets your price range and shows you where your finances are strong or weak.

It is not a final loan offer. The lender still assesses the actual property and your circumstances at the time of the formal application. Used well, a pre-approval is the first step in a long-term property investment strategy.

What Is an Investment Loan Pre-Approval?

An investment loan pre-approval is a conditional indication from a lender of how much you may borrow, subject to a valuation of the property and a final credit check. It usually has a time limit, and the lender can change its position if your income, debts or the property details change.

The main trade-off is that it is not a promise to lend. A pre-approval can lapse or be withdrawn, so timing your property search matters. If you are earlier in the journey, our page on buying your first investment property covers the groundwork.

How Do Lenders Work Out Your Investment Loan Amount?

Lenders assess your investor borrowing by testing whether you could afford repayments at a rate well above the actual loan rate. Banks regulated by APRA must test new borrowers at a rate at least 3.0 percentage points above the product rate.

Rental income helps, but it is discounted. APRA's guidance is that prudent lenders count no more than 80 per cent of expected rent, to allow for vacancy. Lenders also look closely at your existing debts, including credit card limits, which are usually assessed on the limit rather than the balance. Cutting unused card limits before you apply can lift your borrowing power. Our borrowing capacity page explains this further.

Non-bank lenders are not subject to the same APRA serviceability buffer, so their assessments can differ. Their products can carry different pricing and features, so compare the whole package.

Why Interest Only Does Not Raise Your Borrowing Power

Choosing an interest-only loan does not increase how much you can borrow. For interest-only loans, APRA expects lenders to assess repayments as if principal and interest applied over the remaining term after the interest-only period.

As an illustrative example at 6.75% p.a., consider a 30-year loan of $600,000 with a 5-year interest-only period. Interest-only repayments would be about $3,375 a month ($600,000 x 6.75% / 12). When the loan reverts to principal and interest over the remaining 25 years, repayments would be about $4,145 a month at the same rate. A lender assesses you on that higher figure, and at a higher buffered rate, not on the $3,375.

The trade-off is that you do not reduce the loan balance during the interest-only period, so the amount owing stays the same while repayments later rise. Interest on an investment loan is generally deductible for the period the property is rented or genuinely available for rent, but only the interest part of a repayment, not the principal. Speak with your accountant about how this applies to you.

How Much Deposit Does an Investor Need?

Most lenders prefer an investor deposit that keeps the loan at or below 80 per cent of the property value. That 80 per cent loan-to-value ratio (LVR) is the point above which Lenders Mortgage Insurance (LMI) is generally required. It is a lender and insurer policy line, not a legal borrowing limit.

Borrowing above 80 per cent needs approval from both the lender and the LMI insurer. The LMI premium is paid by the borrower and rises with the loan size and LVR, so it adds to your upfront cost. Your deposit, and costs such as stamp duty, should be mapped out before you apply. Your broker can show you how different deposit sizes change your options.

Using Equity in a Pre-Approval for Your Next Purchase

If you already own property, equity can fund the deposit on your next one. Equity is the gap between your property's value and the loan against it, and lenders will only let you borrow part of that gap, with limits that vary by lender.

Consider a Brisbane owner with an existing investment property and a loan well below 80 per cent LVR. A broker arranges a pre-approval that includes a separate loan secured on the existing property to cover the deposit and costs for the next purchase. The result is that the owner may be able to fund the deposit and costs from equity rather than savings, and has an indication, subject to the lender's final assessment and valuation, that the combined debt can be serviced before bidding.

The trade-off is higher total debt and more exposure if rents fall or rates rise. The deductibility of interest depends on how the borrowed money is used, not on which property secures it. Funds used for private purposes are not deductible, so keep the purposes of each loan split separate and ask your accountant for guidance. For investors who have been with a lender for years, a refinancing review of your investment property can also reveal extra equity to use.

Negative Gearing Changes Brisbane Investors Should Know

The rules on negative gearing now depend on when you buy and what you buy. Properties held at 7:30pm AEST on 12 May 2026 keep full deductibility of rental losses against other income, as do eligible new builds acquired after that date.

From the 2027-28 income year, net rental losses on established residential properties acquired after that time are deductible only against other residential property income, with excess losses carried forward. Properties acquired between 12 May 2026 and 30 June 2027 can be negatively geared under the current rules until 30 June 2027 only.

This changes how an investor should test a purchase, because a property may need to hold up on its own cash flow. The capital gains tax discount also changes for gains accruing from 1 July 2027. These rules are complex and your circumstances matter, so get advice from your accountant before you buy.

Timing Your Pre-Approval Around Your Strategy

Get your pre-approval when you are close to searching, not months ahead. Because validity periods are limited and lenders may reassess you, a pre-approval is most useful when you plan to make offers within its window.

A broker can also review the structure of your whole portfolio, such as how loans are split and whether fixed or variable rates suit each one. A fixed rate gives repayment certainty but can limit extra repayments and may carry break costs if you exit early. A variable rate offers flexibility but exposes you to rate rises. If you want to grow beyond one property, our guide to expanding your property portfolio outlines the next stages. We can also compare options from lenders across Australia, so your structure supports where you want to be in ten or twenty years.
