Proven Tips to Fund Your First Investment Property

Buying your first investment property when you're self-employed introduces an extra layer of uncertainty into a process that already feels uncertain enough.

Lenders treat your application differently from someone on a wage. They want two years of financials, they scrutinise your income variability, and they require evidence that your borrowing capacity can handle both your own living expenses and the cost of holding a rental property that may sit vacant for weeks at a time. When you layer that onto the regulatory environment that now exists around investment lending, the application feels heavier than it needs to.

The insight that matters most is this: lenders assess investment loans using your after-tax income and a rental income estimate that factors in vacancy, and they require proof that your business income is stable and likely to continue. Self-employed applicants can meet that test, but only when their financials are structured to show consistency and the loan structure matches the way they manage cash flow.

How Lenders Assess Self-Employed Borrowers for Investment Loans

Lenders calculate your borrowing capacity using your net business income after tax, not your turnover. They apply a 3.0 percentage point serviceability buffer above the loan rate, and they assess your ability to service both your existing home loan (if you have one) and the new investment loan at the same time. Rental income is included in the calculation, but it's discounted to account for periods when the property is empty. Most lenders apply a haircut of 20 to 30 per cent, depending on the property type and location.

For self-employed applicants, the evidence required includes tax returns for the previous two financial years, notices of assessment from the ATO, and business activity statements covering the most recent quarters. If your business structure involves a trust or company, lenders also review the entity's financials and may assess your income based on distributions or director's salary. Where income has been variable across the two years, some lenders will average it, while others take the lower year. This is where the structure of your tax return becomes directly relevant to how much you can borrow.

You can explore how these factors translate into a borrowing figure using a borrowing capacity assessment before you start looking at properties.

Interest-Only or Principal and Interest for First Investment Property

You can structure an investment loan as either interest-only or principal and interest. Interest-only loans require lower monthly repayments because you're not repaying the principal balance during the interest-only period, which typically runs for one to five years. Lower repayments improve your borrowing capacity and free up cash flow, which is useful when you're self-employed and managing irregular income.

Principal and interest loans cost more each month but reduce your debt over time and may attract a slightly lower interest rate. If your business income is steady and you're confident in your ability to service higher repayments, this structure builds equity faster and positions you for further property purchases down the track.

Consider a buyer who runs a trade business and purchases a unit in Baldivis as their first investment. Their after-tax income supports the repayments, but their cash flow fluctuates depending on the timing of invoices and materials payments. They choose an interest-only period for the first three years, which lowers the monthly repayment and gives them room to manage uneven income months without drawing on savings. After three years, when the business income has become more predictable, they switch to principal and interest. The structure matched the cash flow reality at each stage.

Variable or Fixed Rates for Property Investment

Variable rates move with the market. Fixed rates lock your repayments for a set period, typically one to five years. Variable loans usually offer offset accounts and unlimited additional repayments, which means you can reduce your interest cost when you have surplus cash. Fixed loans restrict those features but provide repayment certainty.

For self-employed buyers, the choice depends on whether repayment certainty or flexibility matters more in your specific situation. If you expect lumpy income and want the ability to park surplus funds in an offset account between jobs or invoicing cycles, a variable loan with an offset is usually the more practical option. If your concern is budgeting and you want to lock in the cost for a period while your business income stabilises, a fixed rate achieves that.

Some investors split their loan, fixing a portion and leaving the rest variable. This approach gives partial certainty while retaining access to offset and repayment flexibility on the variable portion.

Deposit Requirements and Lenders Mortgage Insurance

Most lenders require a minimum 10 per cent deposit for an investment property, though a 20 per cent deposit avoids Lenders Mortgage Insurance. LMI is a one-off premium added to your loan amount when you borrow above 80 per cent of the property value. The premium is calculated on a sliding scale based on your loan amount and loan-to-value ratio, and it increases the total amount you're borrowing.

Some lenders allow you to use equity in your existing home as the deposit for your investment property. This means you don't need to have saved cash, but it does increase the total debt secured against your assets. Lenders assess your capacity to service both loans, and they apply the same income verification requirements as they would for a cash deposit.

For self-employed applicants, demonstrating genuine savings over a period of three months is often a lending requirement at higher LVRs, and lenders want to see that those savings weren't introduced as a one-off injection close to application.

Tax Deductions and Negative Gearing for Established Properties

Interest on your investment loan is deductible against your rental income, as are ongoing holding costs including property management fees, council rates, insurance, repairs, and depreciation. Where your rental income is less than your total expenses, the property is negatively geared, and the loss reduces your overall taxable income.

For properties held before 7:30pm AEST on 12 May 2026, or properties under contract awaiting settlement at that time, losses remain fully deductible against all income, including your self-employment income, until you sell. For established properties purchased after that date, losses from the 2027-28 income year onward can only be offset against income from other residential properties, not against your business income or wages. Losses that can't be used in a given year are carried forward.

Eligible new builds remain exempt, meaning losses on those properties continue to be deductible against all income. A new build is defined as a dwelling constructed on previously vacant land or a dwelling that increases the total number of dwellings on a site. Knock-down rebuilds that don't increase dwelling numbers do not qualify.

For self-employed buyers, the change in negative gearing treatment means the tax benefit you receive from holding an established investment property purchased after May 2026 depends on whether you have other residential property income to offset it against. If this is your first property and you're buying an established dwelling, the deduction is quarantined unless you have capital gains from a residential property sale in the same year or future years.

Rental Income and Vacancy Assumptions in Serviceability

Lenders include rental income in your serviceability calculation, but they don't accept the full advertised rent. They apply a discount, typically 20 to 30 per cent, to account for vacancy periods, maintenance downtime, and the possibility that a tenant doesn't pay. The exact percentage depends on the lender's policy and the type of property.

In areas with higher vacancy rates or where rental supply exceeds demand, lenders may apply a more conservative discount. In tightly held rental markets, the discount may sit at the lower end of the range. Either way, the income you can actually use to support your application is materially lower than the weekly rent you expect to collect.

For self-employed buyers, this haircut affects your borrowing capacity in the same way it does for wage earners, but the impact is often more pronounced because your base income is already being assessed conservatively.

Structuring Your Loan Application as a Self-Employed Buyer

The structure of your tax return directly affects how much you can borrow. Lenders calculate your income after deductions, so if you've minimised your taxable income to reduce your tax liability, you've also reduced your borrowing capacity. You can't produce a separate income figure for the lender that differs from what you declared to the ATO.

If you're planning to apply for an investment loan within the next 12 months, it's worth reviewing your tax structure with your accountant before lodging your next return. In some cases, reducing deductions or restructuring distributions can increase your assessed income without materially affecting your after-tax position.

Lenders also assess your existing liabilities, including credit cards, car loans, personal loans, and any buy-now-pay-later accounts. Even if you pay those balances off each month, lenders assume you're using the full limit when calculating your capacity. Closing unused accounts or reducing credit limits before you apply improves your serviceability.

Where you're purchasing in an area like Rockingham or Gosnells, where investment stock is common and rental yields are relatively high, the rental income component of your application plays a larger role. Lenders are familiar with those markets, and they're more likely to accept rental estimates at the higher end of the range when the property type and location support it. Working with a broker who understands investment loans and the Perth rental market means your application is structured to reflect that.

Choosing the Right Loan Product for Your First Investment

Not all lenders offer the same loan features, and not all features matter equally when you're self-employed. Offset accounts, redraw facilities, and the ability to make extra repayments without penalty are all valuable, but the one that matters most depends on how you manage your business cash flow.

An offset account sits alongside your loan and reduces the interest you're charged based on the balance in the account. If you hold surplus cash in your business or personal accounts between invoicing cycles, an offset allows you to reduce your interest cost without locking that cash into the loan. Redraw facilities allow you to access extra repayments you've made, but access is at the lender's discretion and some lenders restrict redraw on investment loans.

Some lenders also allow you to split your loan into multiple accounts, which is useful if you want to fix part of your loan and leave part variable, or if you want separate offset accounts for different purposes.

You'll also want to understand the rate discount available on each product. Lenders offer different rates depending on the LVR, loan amount, and whether the loan is for investment or owner-occupied purposes. Investment loans typically attract a higher rate than owner-occupied loans, and interest-only loans attract a higher rate than principal and interest loans.

Capital Gains Tax from 1 July 2027

From 1 July 2027, capital gains on residential investment properties are taxed under a new framework that replaces the 50 per cent CGT discount with cost base indexation and a 30 per cent minimum tax rate. The change applies to gains accruing from 1 July 2027 onward. For properties purchased before that date, gains are split, with the portion accruing before 1 July 2027 taxed under the existing 50 per cent discount rules and the portion accruing after that date taxed under the new rules.

You can either obtain a market valuation as at 1 July 2027 or use an ATO apportionment formula to split the gain. Under the new rules, you index your cost base for inflation and pay tax on the real gain only, but the tax rate on that gain is at least 30 per cent, even if your marginal rate is lower.

For eligible new builds, you can choose between the old 50 per cent discount and the new indexation treatment when you sell. The ability to choose gives you flexibility depending on how inflation and your marginal tax rate interact at the time of sale.

For self-employed buyers, the timing of a property sale may now carry additional tax planning considerations, particularly if you're holding the property for a long period and expect inflation to erode a significant portion of the nominal gain.
