Investment Loan Pre-Approval: What Not to Do

Why Pre-Approval Matters Before You Make an Offer

Pre-approval tells you exactly what you can borrow before you sign a contract. That matters when you're bidding at auction or working to a 30-day settlement, because conditional finance clauses don't always protect you if the lender changes their mind or if something in your application wasn't quite right the first time.

In our experience, investors who skip pre-approval often scramble to find alternate finance or lose their deposit when the deal falls over. The lender assesses your income, liabilities, and serviceability upfront, then issues a letter confirming they'll lend a specific amount subject to property valuation and final checks. That letter gives you confidence to make an offer and gives the vendor confidence you'll settle on time.

Getting loan pre-approval before you start looking is even more important now that APRA's debt-to-income cap limits how many loans above six times income a lender can write. If your borrowing sits near that threshold, some lenders will decline applications they might have approved 18 months ago. Pre-approval shows you which lenders will say yes and at what rate before you commit to a contract.

How Shift Work and Allowances Affect Your Borrowing Amount

Most lenders will assess 100 per cent of your base salary and between 80 and 100 per cent of regular allowances such as shift penalty rates, on-call payments, and overtime that appear consistently on your payslips. The exact treatment depends on the lender's policy and how your employer codes the payment.

Consider an officer on a base salary around $90,000 who regularly earns another $15,000 in shift penalties and overtime. If the lender accepts 100 per cent of those allowances, the assessed income jumps to $105,000. That difference can add $70,000 or more to your maximum loan amount, depending on your other commitments. If you're already carrying a car loan or personal debt, the shift loading often makes the difference between approval and decline.

We regularly see applications declined or capped lower than expected because the broker or applicant didn't provide the right evidence upfront. The lender wants at least three months of payslips showing the allowances, a letter from your employer confirming the payments are ongoing, and sometimes a full payroll breakdown. Gather that paperwork before you apply, not after the lender asks for it.

Investment Loan Serviceability Under the New DTI Cap

From February, APRA capped the share of new loans a lender can write at debt-to-income ratios of six times or more. The cap applies separately to investor lending and owner-occupier lending, so the restriction bites harder if you're buying investment property because you're competing for a smaller pool of approvals.

The lender calculates DTI by dividing your total debt by your gross income. If you earn $105,000 and want to borrow $580,000 for investment property while still carrying a $350,000 home loan and a $20,000 car loan, your total debt is $950,000 and your DTI is just over nine times. That application will count against the lender's 20 per cent cap, and if they've already written their quota for the quarter, they'll decline you even if you can service the repayments.

Some lenders manage the cap by reserving capacity for repeat customers or higher-value loans. Others simply close their doors to high-DTI applications once they hit the limit. Pre-approval lodged early in the quarter has a better chance than the same application lodged in late March or late June when lenders are close to their caps.

Rental Income and How Lenders Assess It

Lenders will include rental income in your serviceability calculation, but they won't count the full amount. Most apply a shading rate of 80 per cent to account for vacancy, maintenance, and periods between tenants. If the property will rent for $500 per week, the lender adds $20,800 per year to your income, not $26,000.

The other catch is that lenders usually won't accept rental income from the property you're buying until you provide a signed lease or a rental appraisal from a licensed property manager. At pre-approval stage, you don't yet have a property, so the rental income can't be included in the first assessment. That means your existing income has to service the new loan in full until you go to formal approval with a contract and rental evidence.

If you're buying in an area with high vacancy rates or seasonal rental demand, some lenders will shade the income even further or decline the application altogether. They assess risk based on postcode and property type, so a unit in an oversupplied precinct will be treated more conservatively than a house in a tightly held suburb.

Interest-Only Versus Principal-and-Interest Repayments

Most investors choose interest-only repayments for the first one to five years because the lower repayment improves cash flow and frees up serviceability to borrow again sooner. The lender still assesses your ability to service the loan on a principal-and-interest basis, but you only pay interest each month until the interest-only period ends.

At current variable rates, a $400,000 loan on interest-only costs around $1,900 per month. The same loan on principal-and-interest over 30 years costs closer to $2,400 per month. That $500 difference each month can be directed into offset, used to service another loan, or reinvested. The downside is that you're not reducing the debt, so your equity growth depends entirely on capital appreciation.

Interest only loans for police officers are widely available, but not every lender offers the same interest-only period or the same rate discount. Some will only approve interest-only if your loan-to-value ratio is below 80 per cent. Others charge a higher rate for interest-only or restrict the term to three years instead of five. Those differences matter when you're comparing pre-approvals from multiple lenders.

How the New Negative Gearing Rules Change Your Strategy

From 1 July 2027, rental losses on residential property bought after 7:30pm on 12 May 2026 can only be offset against other rental income or carried forward. You can't offset those losses against your salary anymore unless the property qualifies as an eligible new build.

That rule doesn't affect pre-approval directly, but it does change the financial case for buying established property as an investment. If you were planning to negatively gear and claim the loss against shift income, that strategy now only works if you buy a new dwelling that increases the housing stock. Knock-down rebuilds that don't add dwellings, and off-the-plan apartments in buildings that were already occupied, don't qualify.

If you're weighing up an established unit versus a house-and-land package, the new rules tilt the equation toward new builds. The lender's serviceability assessment won't change, because they've never counted the tax benefit of negative gearing when calculating what you can borrow. But your after-tax cash flow will be worse with an established property, and that affects whether the investment stacks up over the long term.

What Happens After Pre-Approval

Pre-approval is usually valid for three to six months, depending on the lender. Once you have a contract, you return to the lender with the sale documents, and they order a valuation. If the property values at or above the purchase price and nothing in your financial position has changed, the approval converts to formal approval and you move to settlement.

If the valuation comes in low, the lender will only finance up to the lower figure. You'll need to make up the shortfall with additional deposit or renegotiate the purchase price. If your income or liabilities have changed since pre-approval, the lender reassesses serviceability and may reduce the approved amount or decline the application altogether.

The most common reason pre-approvals fall over is that the applicant takes on new debt between pre-approval and formal application. A car loan, a higher credit card limit, or even multiple hard credit inquiries can affect serviceability enough to void the original approval. Treat your pre-approval as conditional on nothing changing, and check with your broker before making any financial commitments while the approval is live.

Choosing the Right Loan Structure at Pre-Approval Stage

You don't need to lock in every loan feature at pre-approval, but you do need to decide on loan amount, loan type (variable or fixed), repayment type (interest-only or principal-and-interest), and loan-to-value ratio. Those settings determine which lenders will approve you and at what rate.

If you plan to use equity from your home to fund the deposit, the broker structures that as a separate split or top-up on your existing loan. The investment loan itself should be kept completely separate so that all interest on that loan is deductible. Mixing purpose within a single loan account creates problems at tax time, because the ATO will only allow a deduction for the portion of interest that relates to the investment.

Equity release loans for police officers are common when you're buying investment property without selling your home, but the structure has to be right from the start. Pre-approval is the time to get that structure confirmed, not after you've signed a contract and the settlement clock is running.
