When to Use an Investment Loan for Property Purchase

What an Investment Loan Actually Is

An investment loan is a home loan used to purchase a property you intend to rent out rather than live in. The loan itself looks similar to an owner-occupier loan, but lenders assess your application differently because rental income is part of the picture and risk is measured differently.

Lenders typically shade rental income by 20 per cent to account for vacancy periods and maintenance costs. If you buy a unit in Rochedale and the rental appraisal shows $480 per week, the lender will count $384 per week in your serviceability calculation. That shading affects how much you can borrow, so the figure on your rental appraisal matters from day one.

How Lenders Assess Your Application

Lenders assess your borrowing capacity by adding your existing income to the shaded rental income, then subtracting your living expenses, other loan commitments, and the new loan repayments calculated at a buffer rate. That buffer sits at 3 percentage points above the actual loan rate under current APRA guidance.

Since 1 February, a debt-to-income cap has also applied. Lenders can fund up to 20 per cent of their new investor loans at six times your gross income or higher. The remaining 80 per cent must sit below that ratio. If your household income is $120,000 and you want to borrow $750,000, your DTI is 6.25. That loan will fall into the lender's restricted allocation, so approval depends on how much of that quota remains when your application lands. Properties classified as new builds under APS 220 are exempt from the DTI cap, which has shifted some buyer interest toward newer stock in growth corridors such as Ripley and Springfield.

You will also need a deposit. Most lenders require at least 10 per cent genuine savings for an investment purchase, though some accept 5 per cent if you pay Lenders Mortgage Insurance. Genuine savings means funds held in your name for at least three months. A tax refund counts, but a cash gift from family typically does not unless it has been sitting in your account long enough.

Interest-Only or Principal-and-Interest Repayments

Investment loans can be structured as interest-only for an initial period, usually between one and five years, after which they revert to principal-and-interest. Interest-only repayments lower your monthly outlay, which can help with cash flow if the property is negatively geared.

Consider a buyer who purchases a townhouse in Calamvale with a loan of $520,000 at a variable rate. On interest-only terms, monthly repayments sit around $2,600. On principal-and-interest terms, repayments would be closer to $3,400. The difference matters if rental income is $480 per week and other holding costs such as body corporate fees, rates, and insurance add another $250 per month. The property runs at a monthly shortfall either way, but the interest-only structure keeps that shortfall smaller during the early years.

The downside is that you are not reducing the loan balance, so the debt remains the same while property values fluctuate. When the interest-only period ends, repayments step up significantly. Some buyers use the lower repayment period to build savings or pay down other debts before the revert date arrives.

Variable or Fixed Rates for Investment Property

Most lenders offer both variable and fixed rate options on investment loans. Variable rates move with the lender's decisions, which typically follow Reserve Bank settings. Fixed rates lock in for a set term, usually one to five years, and provide repayment certainty during that window.

Variable rates on investment loans currently sit higher than owner-occupier rates, reflecting the additional risk lenders assign to investment lending. The gap is usually between 0.30 and 0.60 percentage points depending on your loan-to-value ratio and the lender. Fixed rates for investors are also priced higher than fixed rates for owner-occupiers.

If you fix your rate and need to exit the loan early, break costs apply. These are calculated based on the difference between your fixed rate and the lender's current wholesale funding cost for the remaining fixed period. Break costs can run into thousands of dollars if rates have fallen significantly since you locked in. Variable loans avoid that issue but expose you to rate rises during the loan term.

Recent Changes to Negative Gearing and Capital Gains

From 1 July 2027, net rental losses on residential investment properties purchased after 7:30pm on 12 May 2026 can only be offset against other residential rental income or carried forward. You cannot offset those losses against salary or wage income unless the property qualifies as an eligible new build.

An eligible new build is a dwelling constructed on previously vacant land, or a property where the number of dwellings on the site has increased. A knock-down rebuild that replaces one house with one house does not qualify. A development that replaces one house with two townhouses does. If a new build is occupied for more than 12 months before being sold to an investor, the next buyer loses access to negative gearing under the old rules.

Properties you already own or have under contract before 7:30pm on 12 May 2026 are grandfathered. You can continue to negatively gear those properties under the existing rules until you sell. Properties purchased between 12 May 2026 and 30 June 2027 can be negatively geared under the old rules until 30 June 2027 only.

The capital gains tax discount is also changing from 1 July 2027. The current 50 per cent discount for individuals is being replaced with cost base indexation and a minimum 30 per cent tax rate on real gains. The change applies only to gains accrued after 1 July 2027. Gains you have built up before that date remain under the existing discount. Eligible new builds will allow you to elect between the 50 per cent discount and the indexation method when you eventually sell.

Borrowing for a Second Property When You Already Own Your Home

If you already own your home and want to buy an investment property, lenders will assess your capacity based on your current debts and the new loan you are applying for. Your existing home loan repayments are factored in, along with the buffered repayments on the new investment loan and any other commitments such as car loans or credit card limits.

Some buyers release equity from their home to fund the deposit on the investment property. If your home is worth $650,000 and your loan balance is $380,000, you have $270,000 in equity. Lenders will typically allow you to borrow up to 80 per cent of your home's value across all loans secured against it, which would be $520,000 in this case. You could refinance your home loan to $520,000, releasing $140,000 to use as a deposit and cover purchase costs on the investment property.

Using equity avoids the need to save a cash deposit, but it increases your total debt and the interest you pay. It also means your home is now security for both loans, so if the investment property underperforms or vacancy runs longer than expected, your home is exposed. Lenders assess this type of application carefully, and your serviceability needs to cover repayments on both properties plus a buffer.

Loan-to-Value Ratio and Lenders Mortgage Insurance

Your loan-to-value ratio is the loan amount divided by the property's value. If you borrow $450,000 to buy a property valued at $500,000, your LVR is 90 per cent. Most lenders charge LMI on investment loans above 80 per cent LVR. The premium can range from a few thousand dollars to over $20,000 depending on the loan size and LVR.

LMI protects the lender if you default and the property sells for less than the outstanding loan balance. It does not protect you. The premium is usually added to the loan balance rather than paid upfront, so you end up paying interest on it over the life of the loan. Some lenders offer LMI waivers for certain professions or if you meet specific criteria, though these are less common on investment loans than on owner-occupier loans. You can explore options with our team if you want to understand what is available based on your occupation and deposit size.

Structuring Loans When You Plan to Expand Your Portfolio

If your goal is to buy more than one investment property over time, how you structure your first loan affects how easy it is to borrow again later. Lenders assess each new application based on your current debt position, so minimising non-deductible debt and maintaining clean serviceability makes the next purchase more viable.

Some buyers split their loans into separate accounts, with one loan secured against the investment property and another against their home. This separation makes it easier to track deductible interest and manage repayments if you decide to sell one property but keep the other. It also gives you the option to refinance one loan without touching the other, which can be useful if your circumstances change or if one lender offers a better rate on investment lending than another.

Rental Income, Vacancy Periods, and Cash Flow

Rental income is not guaranteed. Tenants move out, properties sit vacant, and maintenance costs arrive without warning. Lenders assume an 80 per cent rental income factor in their serviceability calculations, but your actual cash flow can vary more than that.

A unit in Algester with a rental appraisal of $420 per week generates $21,840 per year if tenanted continuously. A four-week vacancy drops that to $20,160. Add $3,500 in body corporate fees, $2,200 in rates, $800 in landlord insurance, and $1,500 in maintenance, and your holding costs before loan repayments are $8,000. Rental income nets $12,160 after those costs. If your interest-only loan repayments are $28,000 per year, the property costs you $15,840 annually before tax.

That shortfall is common in the early years of property ownership, particularly in Queensland where yields in many suburbs sit between 4 and 5 per cent. Negative gearing can reduce your taxable income if the property was purchased before the May 2026 announcement date, but the cash flow gap still needs to be funded from your salary or other income. Make sure you can carry that shortfall for an extended period if rental conditions soften or interest rates rise further.

What Lenders Want to See in Your Application

Lenders want evidence that you can service the loan under stress conditions and that the property represents acceptable security. That means providing payslips, tax returns if you are self-employed, bank statements showing your savings history, and a rental appraisal or signed lease if the property is already tenanted.

Your credit file will be checked. Late payments, defaults, or high credit card utilisation can reduce your borrowing capacity or lead to a decline. Lenders also review your existing debts, including personal loans, car finance, HECS, and credit card limits. Even if you pay your credit card in full each month, the lender will assume you could draw the full limit and factor that into your serviceability.

If you are buying a unit, the lender will want to see a body corporate report showing the sinking fund balance, any special levies planned, and whether the building has any structural issues. If the report flags problems or if the sinking fund is underfunded, the lender may decline the application or reduce the amount they are willing to lend.

Why Loan Features Matter More Than Rate Alone

Investment loan interest rates vary between lenders, but the features attached to the loan often matter more than a 0.10 percentage point difference in rate. An offset account linked to your investment loan lets you park surplus cash and reduce the interest charged without making extra repayments that you cannot easily access later. That flexibility is valuable if you plan to expand your property portfolio or if you want to keep funds available for other investments.

Some lenders allow unlimited extra repayments and free redraws on variable rate investment loans. Others cap the number of transactions or charge fees for redraw requests. If you are using an interest-only loan structure, redraw is less relevant because you are not paying down the principal, but the feature becomes important once the loan reverts to principal-and-interest.

Portability is another feature worth checking. If you sell the investment property and buy another within a short window, some lenders let you transfer the loan to the new property without refinancing. That saves on discharge fees, application fees, and valuation costs. Not all lenders offer this, and those that do often impose conditions around timing and loan balance.
