An investment loan is the finance you use to purchase a property you intend to rent out rather than live in. Lenders price and structure these loans differently to owner-occupier home loans because rental income supports the repayment, the tax treatment differs, and the regulatory settings around investor lending have changed significantly in the past two years.
If you're weighing up whether to buy your first investment property or add another to your portfolio, the way lenders assess your application now involves more moving parts than it did a few years ago. The debt-to-income limit that came into force in February means lenders can only write a fixed proportion of new investor loans to borrowers with total debt above six times their gross income, and that's reshaping how much you can borrow and which lenders will say yes.
How Lenders Assess Investment Loan Applications Now
Lenders assess your ability to service an investment loan using your current income, your existing debts, and the rental income the new property will generate. They don't use the full rent you expect to collect. Most lenders apply a shading factor between 70 and 80 per cent to account for periods when the property sits vacant or tenants don't pay. If the rent is $600 per week, the lender might only count $450 in their serviceability calculation.
On top of that, every lender must test your ability to repay the loan at an interest rate that's at least 3 percentage points above the actual rate you'll pay. If your investor interest rate is 6.5 per cent, the lender assesses you at 9.5 per cent or higher. Combined with the debt-to-income cap, this means your borrowing capacity as an investor is often lower than you expect, particularly if you already have a home loan or investment debt.
Consider a buyer who earns $120,000 per year and already has an owner-occupier loan with $450,000 outstanding. They want to buy a unit in Morningside to rent out. Their total debt-to-income ratio before the new loan is 3.75. If they borrow another $600,000 for the investment property, their total debt climbs to $1,050,000 and their DTI ratio becomes 8.75. That places them above the six-times threshold, so not every lender will have capacity to approve the loan in a given quarter. The lender that does approve it will apply both the serviceability buffer and the rental shading, which together reduce how much they're willing to lend.
Interest Only or Principal and Interest Repayments
Most investors choose interest-only repayments for the first few years to keep cash flow manageable and maximise their tax deductions. When you pay interest only, the entire interest component is deductible against your rental income and other income (for properties held before mid-May or eligible new builds). The loan balance doesn't reduce, but your monthly outgoing is lower, which can be useful if you're holding multiple properties or building equity elsewhere.
Interest-only periods typically run for one to five years, after which the loan converts to principal and interest unless you apply to extend it. Lenders generally allow one or two extensions, but policy varies. If the loan converts to principal and interest, your repayments jump because you're now paying down the debt as well as covering the interest cost.

Principal and interest repayments from the start mean your loan balance reduces each month and you build equity faster. The downside is a higher monthly repayment and a slightly smaller immediate tax deduction, because part of each payment is principal rather than interest. Some investors prefer this structure if they're planning to sell within a few years or if they want to reduce their overall debt position ahead of retirement.
Variable or Fixed Interest Rates for Investment Property
Investor interest rates are typically higher than owner-occupier rates, and the gap widens if you choose interest only. A variable rate moves with the market, so your repayments can rise or fall depending on what the Reserve Bank and your lender do with rates. Most variable investment loans come with an offset account, which lets you park savings against the loan balance and reduce the interest charged without affecting your ability to claim the full interest deduction.
Fixed rates lock in your repayment for a set period, usually one to five years. If rates rise during that time, you're protected. If they fall, you're stuck. Fixed rate loans often don't allow offset accounts, and breaking the fixed term early can trigger substantial break costs if market rates have dropped since you locked in.
In our experience, investors who want certainty in their cash flow or who are stretching their serviceability lean toward a fixed rate, while those who value flexibility and offset benefits stick with variable. Splitting the loan between fixed and variable is another option, though it adds some administrative complexity and may not suit smaller loan amounts.
Deposit Requirements and Loan to Value Ratio
Most lenders cap investor loans at 90 per cent of the property's value, meaning you need at least a 10 per cent deposit plus costs. Borrowing above 80 per cent triggers Lenders Mortgage Insurance, which is a one-off premium calculated on the loan amount and LVR. LMI protects the lender if you default, but you pay for it. The premium can run into the thousands and is usually capitalised into the loan, though paying it upfront can sometimes reduce the cost slightly.
If you're using equity from your existing home to fund the deposit, the lender will revalue that property and calculate how much equity is available after accounting for your outstanding loan. Usable equity is typically capped at 80 per cent of the property's current value, minus what you owe. That figure then becomes your deposit for the investment purchase, though you still need to cover stamp duty and other settlement costs separately.
Some lenders offer no LMI loan options for certain professions or under specific portfolio lending arrangements, but these are less common for investment properties than for owner-occupier purchases. Policy changes frequently, so it's worth checking what's available at the time you're ready to buy.
Tax Treatment for Investment Property Loans
Interest on an investment loan is deductible against your assessable income if the property is rented or genuinely available for rent. Other holding costs, including council rates, insurance, property management fees, body corporate levies, and repairs, are also deductible. If your total deductions exceed your rental income, you make a loss on paper, and that loss reduces your taxable income from other sources like salary. That's negative gearing, and it remains available for properties held before mid-May or for eligible new builds.
For established properties acquired after mid-May, losses from the 2027-28 income year onward can only be offset against other residential property income, not against salary. Unused losses carry forward to future years. Capital gains tax arrangements are also changing from July next year, with cost base indexation replacing the 50 per cent discount for gains accruing after that date. Eligible new builds retain access to both the existing discount and the new indexed treatment, giving investors a choice at sale time.
These changes don't affect properties already owned or under contract before mid-May, and they don't apply to new builds that meet the eligibility criteria. If you're buying an established unit or house in Morningside after that date, your accountant will need to track the property's tax treatment separately from any other investments you hold.
Rental Income and Vacancy Rates in Morningside
Morningside sits within the 4170 postcode and borders Hawthorne, Balmoral, and Norman Park. The area attracts a mix of young professionals, families, and students due to its proximity to the CBD, Oxford Street cafe precinct, and Bulimba's riverfront. Rental demand has been solid, supported by limited new apartment supply and the suburb's established character. Vacancy rates across the inner east have been low, though individual properties can still sit empty between tenants, particularly if they're priced above market or need maintenance.
When a lender assesses your investment loan application for a Morningside property, they'll use the rent you provide in your application but shade it as described earlier. If you're buying a unit near Lytton Road with an expected rent of $550 per week, the lender might count $410 to $440 in their serviceability calculation. That gap is larger than many buyers expect, and it directly affects how much you can borrow.
Structuring the Loan and Choosing the Right Product
Every lender prices and structures investment loan products differently, and the gaps between them have widened as lenders manage their exposure to the DTI limits and adjust their risk appetite for investor lending. Some lenders offer rate discounts for larger loans or lower LVRs. Others price more aggressively for interest-only loans or offer better offset account features. A few lenders allow longer interest-only periods or more flexible prepayment terms, which can matter if your circumstances change.
If you're buying your first investment property, you'll usually borrow in your personal name or jointly with a partner. If you're building a portfolio, you might eventually look at structuring through a trust or company, though that brings additional costs and complexity and usually means higher interest rates. Most portfolio investors we work with hold their first few properties in personal names and only move to a trust structure once they're confident the strategy is working and the tax and asset protection benefits justify the extra admin.
Choosing the right lender upfront matters more than it used to. If you outgrow a lender's policy settings or your circumstances shift, refinancing an investment loan is straightforward in theory but can trigger valuation shortfalls, particularly if property values have softened or if your income or debts have changed. Locking in a loan structure that gives you room to grow avoids that problem.

Frequently Asked Questions
What deposit do I need to buy an investment property in Morningside?
Most lenders require at least 10 per cent of the property value plus settlement costs, though borrowing above 80 per cent triggers Lenders Mortgage Insurance. If you're using equity from an existing property, lenders typically allow you to access up to 80 per cent of that property's value minus what you owe.
Can I still negatively gear an investment property I buy now?
Yes, if you're buying an eligible new build or if you held the property before mid-May. For established properties acquired after that date, negative gearing losses can only offset other residential property income from the 2027-28 income year onward, not salary or wages.
How much rental income will the lender count toward my borrowing capacity?
Lenders apply a shading factor of 70 to 80 per cent to the expected rent to account for vacancies and unpaid rent. If the property rents for $600 per week, the lender may only count $450 to $480 in their serviceability assessment.
Should I choose interest only or principal and interest repayments?
Interest-only repayments keep your monthly outgoing lower and maximise your immediate tax deduction, but your loan balance doesn't reduce. Principal and interest repayments are higher each month but build equity faster and reduce your overall debt position.
What is the debt-to-income limit for investment loans?
From February, lenders can only write up to 20 per cent of new investor loans each quarter to borrowers with total debt of six times their gross income or more. If your DTI is above six, not every lender will have capacity to approve your application in a given quarter.
