How to Get Pre-Approval for an Investment Loan

Pre-approval for an investment loan gives you a clear picture of how much you can borrow before you start looking at properties.

It's not a guarantee, but it confirms what lenders are willing to offer based on your current financial position. For Perth investors, this matters because it shapes your search parameters and signals to selling agents that you're a credible buyer. The difference between searching with pre-approval and without it is the difference between focused action and speculative browsing.

What Lenders Assess During Pre-Approval

Lenders calculate your borrowing capacity by looking at your income, existing debts, living expenses, and the rental income the property is likely to generate. They'll also factor in your deposit size and the loan to value ratio you're aiming for. Most lenders assume the property will be vacant for part of the year, so they'll only count around 80% of the expected rental income when assessing your application. That's called shading, and it protects both you and the lender from overcommitting based on optimistic rental projections.

Consider a buyer who earns a consistent wage, has no dependents, and holds a 20% deposit. That buyer will have access to far more investment loan options than someone with irregular income or a smaller deposit, even if their household spending is identical. Lenders also assess your credit history, employment stability, and whether you've held your current role for at least six months. If you're self-employed, they'll typically want two years of financials.

How Rental Income Affects Your Borrowing Capacity

Rental income boosts your borrowing power, but not dollar for dollar. Lenders apply a shading rate, meaning they'll only recognise a portion of the rent when calculating what you can afford to repay. If a property in Joondalup is expected to rent for $600 per week, the lender might only count $480 of that in their assessment. This accounts for vacancy periods, maintenance costs, and the risk that tenants don't always pay on time.

The exact shading percentage varies between lenders, but 80% is common. Some lenders are more generous with established properties that have a strong rental history, while others apply stricter assumptions for apartments or properties in areas with higher vacancy rates. Understanding how your chosen lender treats rental income is part of selecting the right investment loan products for your situation.

Why Deposit Size Changes Your Options

Your deposit determines not just whether you'll pay Lenders Mortgage Insurance, but also which lenders will consider your application and what interest rate you'll be offered. A 20% deposit avoids LMI and opens the door to better rate discounts. Anything below that threshold and you'll pay insurance, which can add thousands to your upfront costs. Some lenders won't offer investor loans at all if your deposit is below 10%, and those that do often charge higher rates or apply stricter servicing criteria.

In our experience, investors who leverage equity from an existing property often have more flexibility than those saving cash. If you own a home in Applecross with sufficient equity, you might be able to access that without selling or disrupting your living arrangements. That equity can form part or all of your deposit, depending on how much is available and what your borrowing capacity supports across both properties.

The Documents You'll Need to Provide

You'll need recent payslips, tax returns if you're self-employed, bank statements showing your savings pattern, and details of any other debts or commitments. Lenders want to see that your deposit has been genuinely saved over time rather than appearing suddenly from an undocumented source. If someone has gifted you part of the deposit, you'll need a signed declaration confirming it's not a loan that needs to be repaid.

For the property itself, lenders will want a copy of the contract of sale once you've found something, plus a valuation to confirm the purchase price aligns with market value. Strata reports are required for units or townhouses, as lenders assess the financial health of the body corporate before approving finance. If the sinking fund is underfunded or there are special levies on the horizon, that can affect your application.

How Long Pre-Approval Lasts and What Happens Next

Most lenders issue pre-approval for 90 days, though some extend it to six months. During that window, your income and financial position are locked in for assessment purposes, so you don't need to resubmit documents every time you make an offer. That said, pre-approval is conditional. If your circumstances change before settlement, such as taking on new debt or changing jobs, the lender can reassess or withdraw the offer.

Once you find a property and go under contract, the lender will conduct a formal valuation and review the contract terms. Assuming nothing has shifted since pre-approval, the process from offer to settlement is usually faster because the heavy lifting has already been done. For investors competing in Perth's northern suburbs like Joondalup, where stock moves quickly, that speed can be the difference between securing the property and missing out.

Interest Only Versus Principal and Interest

Many investors choose interest only repayments for the first few years to maximise cash flow and tax deductions. With interest only, your repayments are lower because you're not paying down the loan balance, which means more of your rental income stays in your pocket. The loan amount remains unchanged during the interest only period, but you're not building equity through repayments.

Principal and interest repayments reduce the loan balance over time, which builds equity faster and reduces the total interest paid across the life of the loan. Some investors prefer this approach if they're focused on long-term wealth accumulation rather than short-term cash flow. Your choice will depend on your property investment strategy, tax position, and whether you plan to hold the property long term or sell within a few years.

Fixed Rate or Variable Rate for Investment Loans

A fixed rate locks in your repayments for a set period, usually one to five years, which makes budgeting predictable. You won't benefit from rate cuts during that time, but you're also protected from rate rises. A variable rate moves with the market, so your repayments can go up or down depending on what the Reserve Bank and your lender decide. Variable loans often come with more flexibility, including offset accounts and the ability to make extra repayments without penalty.

Some investors split their loan between fixed and variable to get the stability of a fixed rate on part of the balance while keeping flexibility on the rest. If you're holding a property in an area like Applecross where capital growth is steady, locking in a portion of your loan might make sense. If you expect rental income to cover most of your repayments and you want the option to pay down the loan faster, a variable rate could be more suitable. We regularly see investors change their view on this depending on what's happening with refinancing opportunities and rate movements.

How the 2026 Budget Changes Affect Pre-Approval Strategies

If you're buying an established property from 13 May 2026 onwards, the recent budget changes will affect how negative gearing and capital gains tax apply from 1 July 2027. Losses from the property will only be deductible against rental income or capital gains from residential property, not against your wage or salary. That doesn't change your borrowing capacity today, but it does change the cash flow profile of the investment once the new rules take effect.

For new builds, the existing arrangements remain available, which means you can still claim losses against other income and choose the more favourable CGT treatment. If you're weighing up an established villa in Joondalup versus a new townhouse in the same area, the tax treatment from mid-2027 onwards is now part of the equation. Pre-approval doesn't factor in tax benefits directly, but understanding how those benefits shift can influence which properties you target and how much rental income you'll actually retain.

When to Get Pre-Approval Before You Start Looking

Get pre-approval before you attend your first inspection. It clarifies what you can afford, filters out properties that don't fit your budget, and gives you confidence when you're ready to make an offer. Agents in Perth take buyers with pre-approval more seriously because they know the finance is likely to proceed without delays or surprises.

Pre-approval also exposes any issues with your application early, while you still have time to fix them. If your living expenses are too high or your credit file has an error, you'll find out during pre-approval rather than after you've signed a contract. That gives you breathing room to adjust your approach, whether that means reducing discretionary spending, paying down a credit card, or waiting a few more months to build your deposit.
