Getting investment loan approval depends on serviceability, not just deposit
Investment loan approval turns on whether the lender believes you can service the loan under stress conditions, not just whether you have the deposit. Every lender in Australia is required to assess your capacity to meet repayments at an interest rate at least 3.0 percentage points above the actual loan rate. That buffer sits on top of the rate you will pay, meaning a variable rate investment loan priced at 6.5 per cent will be assessed at 9.5 per cent or higher. The rental income from the property is included in the assessment, but lenders shade it by 20 per cent to account for vacancy and management costs. If you are self-employed, the lender will also require two full years of tax returns and may average your income across that period rather than taking the most recent year alone.
Consider a buyer looking at a two-bedroom unit in Rose Bay at the suburb's current median. With a 20 per cent deposit, the borrower would need to demonstrate capacity to service a loan of around $1.47 million at the stressed rate, while showing they can continue to meet their existing home loan, living expenses and any other debt. Rental income on a two-bedroom unit in Rose Bay typically sits around $1,200 to $1,400 per week, but the lender will use 80 per cent of that figure in the serviceability calculation. The buyer's taxable income, not gross revenue, becomes the limiting factor.
How the new debt-to-income limit affects investor borrowing
From February, lenders can approve no more than 20 per cent of new investment loans to borrowers whose total debt is six times their annual income or more. The limit applies separately to each lender and is measured quarterly. If your household taxable income is $200,000 and you already have $800,000 in home debt, adding a $600,000 investment loan would push your total debt to seven times income. You would still fall within the serviceability buffer if your income and expenses support it, but you might be competing for a slot within that lender's 20 per cent quota. Non-bank lenders are not currently subject to the debt-to-income cap, which makes them a useful option for borrowers whose income is strong but whose existing debt is high relative to that income.

Why lenders treat investment loans differently from owner-occupied lending
Investment loans attract higher risk weights under the banking capital rules, which flow through to pricing and policy. A lender will typically price an investment loan 0.3 to 0.6 percentage points above an equivalent owner-occupied loan at the same loan-to-value ratio. Interest-only repayment terms, which are common on investment loans, add another margin. At loan-to-value ratios above 80 per cent, Lenders Mortgage Insurance is required and is calculated on a sliding scale. The premium on a 90 per cent loan-to-value ratio investment loan can be two to three times the premium on an equivalent owner-occupied loan, because the insurer is pricing both the higher loan-to-value ratio and the investment purpose.
In our experience, self-employed borrowers in Rose Bay who structure their affairs to minimise taxable income often find their borrowing capacity constrained when they apply for an investment property loan. A borrower running a consulting business through a company and taking a modest salary plus dividends might show $120,000 in taxable income while their actual cash flow is materially higher. Most lenders will assess serviceability on the declared taxable income only, though some will add back depreciation and other non-cash deductions. The solution is not to artificially inflate income in the year of application, but to plan the purchase timeline around the lodgement of two strong years of returns.
What documents lenders require from self-employed investment buyers
Self-employed applicants will need to provide two years of full tax returns including the ATO Notice of Assessment for each year, business financial statements if the business is a company or trust, and recent business activity statements showing consistent income. If you operate through a company, the lender will also want to see a letter from your accountant confirming your ownership share and the company's capacity to continue paying your income. For PAYG borrowers, two recent payslips and a letter of employment are generally sufficient, though lenders will still run a credit check and request recent bank statements to verify living expenses and any undeclared debt. Rose Bay buyers purchasing an investment property while retaining their existing home should be prepared to show how both properties will be serviced simultaneously, particularly if the investment loan will be interest-only and the owner-occupied loan is principal and interest.
Interest-only terms and why most Rose Bay investors choose them
Interest-only repayment terms allow you to hold the loan balance flat while directing surplus cash flow to offset accounts, other investments, or paying down non-deductible debt such as your home loan. Interest on an investment loan is deductible against rental income, while principal repayments are not. For a working professional in Rose Bay holding a $1.2 million home loan and a $500,000 investment loan, paying down the home loan first and keeping the investment loan interest-only will reduce the total interest cost over time, because the non-deductible debt is being cleared faster. Most lenders will approve interest-only terms for up to five years on an investment loan, after which the loan converts to principal and interest unless you apply to extend the interest-only period.
Rental yields in Rose Bay sit around 2.1 to 2.4 per cent for units, which means the property will not cover its own holding costs at current variable rates. The shortfall between interest, body corporate, rates, insurance and rental income is deductible against other income under the existing negative gearing rules for properties held before May, and can be used to reduce your taxable income. Buyers acquiring established properties after May will need to plan for a different tax treatment from the 2027-28 financial year onward, where losses can only be offset against other residential property income rather than salary. Properties classified as eligible new builds remain fully deductible regardless of purchase date. If you are considering an investment loan refinance or purchasing another property, understanding how these rules interact with your specific situation is important before you commit.
How rental income is assessed and why vacancy assumptions matter
Lenders will use the lower of the actual rent being achieved or 80 per cent of a market rent assessment when calculating serviceability. If the property is currently tenanted at $1,300 per week, the lender will use $1,040 per week in the income calculation. If the property is vacant, the lender will order a rental assessment and apply the same 80 per cent shading. That shading accounts for vacancy periods, management fees, and maintenance costs. In Rose Bay, where unit vacancy rates are low and demand from executive tenants is consistent, the 80 per cent figure is conservative, but it is a regulatory requirement and applies regardless of the suburb. The rental income is then added to your employment or business income and tested against all outgoings, including the new investment loan assessed at the stressed rate, your existing home loan, living expenses, and any other debt.
Leveraging equity from your Rose Bay home to fund the deposit
Many buyers in Rose Bay use equity release from their existing home to fund the deposit and costs on an investment property rather than drawing down savings. If your Rose Bay home is worth $5.75 million at the current median and your remaining loan balance is $2 million, you have $3.75 million in equity. A lender will typically allow you to borrow up to 80 per cent of the property value across all loans secured against it, meaning total lending of $4.6 million. That leaves $2.6 million in accessible equity, more than enough to fund a deposit on a second property without selling any assets. The lender will assess your capacity to service both loans simultaneously, and you may need to provide updated income documents and a new valuation on the Rose Bay property. Structuring the lending correctly is important, as you want the investment loan and any deposit loan to be quarantined from your home loan so the interest remains deductible.

Frequently Asked Questions
What income do lenders use to assess investment loan serviceability for self-employed borrowers?
Lenders use your taxable income as declared on your tax return, averaged across two full financial years. Some lenders will add back non-cash deductions such as depreciation, but most assess serviceability on the taxable income figure only, not gross business revenue.
How much rental income will the lender include in my serviceability assessment?
Lenders apply a 20 per cent shading to rental income to account for vacancy, management fees and maintenance. If the property is tenanted at $1,300 per week, the lender will use $1,040 per week in the income calculation.
Can I use equity from my Rose Bay home to fund the deposit on an investment property?
Yes. If you have sufficient equity and can service both loans, most lenders will allow you to borrow up to 80 per cent of your home's value across all loans secured against it. The lender will assess your capacity to service both the existing home loan and the new investment loan simultaneously.
Why do investment loans have higher interest rates than owner-occupied loans?
Investment loans attract higher risk weights under banking capital rules, which increases the lender's cost of providing the loan. That cost is passed through to borrowers in the form of a rate margin, typically 0.3 to 0.6 percentage points above an equivalent owner-occupied loan.
What is the debt-to-income limit and how does it affect investment loan approval?
From February, lenders can approve no more than 20 per cent of new investment loans to borrowers whose total debt is six times their annual income or more. If your debt-to-income ratio exceeds six, you may still be approved if you meet serviceability requirements, but you will be competing for a limited quota at that lender.
