How to Navigate Property Investment Loan Challenges

Serviceability Buffers Are Tightening Investor Borrowing Capacity

Lenders must assess your ability to service an investment loan at a rate 3.0 percentage points above the actual product rate. That buffer, which increased from 2.5 percentage points in late 2021, directly reduces how much you can borrow, particularly when rental income alone doesn't cover the full repayment.

Consider a buyer looking at a two-bedroom unit in Traralgon with an expected rental yield of around $350 per week. At current variable rates, the repayment on a loan of $400,000 might sit comfortably within their income, but the lender will test serviceability as though the rate is three percentage points higher. Once that buffer is applied, the same buyer might only qualify for $340,000, even though they can comfortably afford the actual repayment. The buffer exists to protect against future rate rises, but it also means borrowers need to demonstrate significantly more income or contribute a larger deposit than they might expect.

In practice, we regularly see Gippsland investors who assume rental income will be treated dollar-for-dollar in the serviceability calculation, only to discover that lenders discount it by 20 per cent or more and then apply the buffer on top. If you're planning to hold an investment loan with interest-only repayments, the calculation tightens further, because lenders factor in the eventual reversion to principal and interest.

How the New Debt-to-Income Limits Affect Portfolio Borrowers

From February this year, lenders can only write up to 20 per cent of new investor loans to borrowers with total debt exceeding six times their gross income. If you already hold one or more investment properties and are looking to add another, your combined debt across all loans may push you beyond that threshold, limiting which lenders will approve your application.

Suppose an investor earns $120,000 per year and already owes $500,000 across an owner-occupied mortgage and one investment property. A second investment loan of $250,000 would take their total debt to $750,000, or 6.25 times income. Under the new limit, most lenders will decline that loan unless the investor falls within their 20 per cent exception quota. Because those exceptions are managed on a quarterly basis and aren't disclosed to applicants, there's no way to know in advance whether your application will be approved or whether the quota has already been exhausted.

The restriction doesn't apply to non-bank lenders, but those lenders typically charge higher rates and may require larger deposits. For Gippsland investors building a portfolio in towns like Warragul or Moe, where median property values sit below metro averages, the six-times cap can still bite if wage income hasn't kept pace with acquisition volume.

Interest-Only Loans Are Classified as Higher Risk Under Capital Rules

Investment loans structured as interest-only for more than five years, or without a defined interest-only period, are classified as non-standard under the current prudential framework. That classification increases the capital lenders must hold against the loan, which flows through to pricing and approval criteria.

Most lenders now cap the initial interest-only period at five years and require the loan to revert to principal and interest after that. If you're purchasing a property in Sale or Drouin with the intention of holding it long-term and maximising short-term cash flow, you'll need to structure the loan with that five-year limit in mind and ensure your serviceability can withstand the higher repayment once principal repayments commence.

When lenders assess a long-term interest-only loan at an LVR above 80 per cent, the non-standard classification also affects your ability to refinance later. If your circumstances change or you want to access equity for a future purchase, the loan's classification can limit which lenders will accept the business.

Negative Gearing Rules Have Changed for Properties Acquired After May Last Year

Losses from established residential investment properties acquired after 12 May last year can only be offset against income from other residential properties from the 2027-28 financial year onward. That means if your property expenses exceed rental income, you can't deduct the shortfall against your wage or salary unless the property qualifies as a new build.

For Gippsland investors, the distinction between an established property and a new build carries significant tax consequences. A renovated weatherboard cottage in Morwell, even if extensively updated, remains an established property. A new townhouse built on subdivided land in Traralgon qualifies as a new build, and losses remain fully deductible against all income. The difference can amount to several thousand dollars per year in after-tax cash flow, depending on your marginal rate and the size of the loss.

If you purchased or contracted to purchase before 12 May last year, losses remain fully deductible indefinitely under the grandfathering provision. If you're considering an acquisition now, it's worth confirming with your accountant whether the dwelling meets the new build criteria before proceeding, particularly if negative gearing forms part of your property investment strategy.

Capital Gains Tax Treatment Is Splitting From 1 July Next Year

From 1 July next year, capital gains on residential investment properties will be taxed under a new indexed cost base model for the portion of the gain accruing after that date. Gains accruing before that date remain subject to the 50 per cent discount. Properties classified as new builds allow investors to choose between the old discount method and the new indexed method at the time of sale.

If you're holding a property in Leongatha or Wonthaggi purchased several years ago and expect to sell in the next few years, the transition creates a split calculation. You'll calculate the gain up to 1 July next year under the existing rules, then calculate the gain from that date to the sale date under the indexed rules. You can either obtain a formal valuation as at 1 July next year, or use an ATO apportionment formula once it's published.

For long-term investors, the indexed model may deliver a lower effective tax rate in high-inflation environments, because you only pay tax on real gains above inflation. For shorter hold periods or properties acquired close to the transition date, the 50 per cent discount often remains more favourable. The choice is only available for new builds, so understanding whether your property qualifies affects not just immediate deductions but also the exit outcome years down the line.

Lenders Mortgage Insurance Premiums Are Higher for Investment Loans

When your deposit falls below 20 per cent of the property value, lenders require mortgage insurance, and the premium is calculated on a sliding scale that reflects both the LVR and the loan purpose. Investment loans attract higher premiums than owner-occupied loans at the same LVR, and the premium is a one-off cost added to your loan or paid upfront.

For a $450,000 investment loan with a 10 per cent deposit in a town like Bairnsdale, the LMI premium might sit between $12,000 and $18,000, depending on the lender and the insurer they use. That cost doesn't reduce the amount you need to borrow for the property itself, so your total loan becomes $462,000 to $468,000, which in turn affects serviceability and interest cost over time.

Some lenders allow you to use equity in an existing property to avoid LMI on a new investment purchase, even when the cash deposit is below 20 per cent. If you own a home in Gippsland with accessible equity, that approach can eliminate the premium altogether, though it does increase the total debt secured against your existing property and may require a loan health check to confirm the structure remains sound.

Rental Income Is Discounted in Serviceability Calculations

Lenders do not treat rental income as equivalent to wage income when assessing your ability to service an investment loan. Most lenders apply a discount, known as a shading rate, of between 20 per cent and 30 per cent to account for vacancy periods, maintenance costs and the risk that a tenant may not pay.

If a property in Churchill generates $1,600 per month in rent, the lender might only include $1,120 to $1,280 of that income in the serviceability assessment. The shading rate varies between lenders, and some apply a higher discount for units or properties in regional areas where vacancy rates are perceived to be less stable. That discounting, combined with the three percentage point buffer, means rental income contributes less to borrowing capacity than many investors expect.

In our experience, investors who rely heavily on rental income to service a new loan often need to increase their deposit, reduce the loan amount, or demonstrate additional wage income to meet serviceability thresholds. If you're looking at a self-employed loan structure where your taxable income is already reduced through deductions, the rental shading can compress borrowing capacity further, making it important to model the scenario before committing to a purchase.
