Top Strategies to Overcome Property Investment Challenges

The Serviceability Hurdle That Catches Most Nurse Investors

Banks assess your ability to service an investment loan at a rate 3 percentage points above the actual product rate. This buffer has been in place since late 2021 and remains active under current APRA requirements. For nurses and midwives with shift work income, overtime, or penalty rates, this calculation can exclude a significant portion of your earnings if the lender applies conservative shading to variable income.

Consider a registered nurse earning a base salary of $85,000 plus $18,000 in penalty rates and overtime. Some lenders will shade that variable component by 20 per cent or more, effectively reducing your serviceability income to around $99,400 rather than the full $103,000. When that reduced figure is then tested at a rate 3 percentage points higher than the loan product rate, the amount you can borrow drops further. In a scenario like this, the nurse might qualify for $420,000 instead of $480,000, limiting the suburbs and property types within reach.

We regularly see this play out with nurses who have strong savings discipline and a solid deposit but find their borrowing capacity constrained by how their income is categorised. The solution involves matching you with lenders who recognise nursing income structures and apply minimal or no shading to penalty rates and regular overtime. Not all lenders treat shift work the same way, and that difference can add tens of thousands to your borrowing capacity. If you already own a home and are looking to purchase your first investment property, understanding how lenders assess rental income is equally important. Some lenders apply an 80 per cent shading to rental income to account for vacancy and maintenance costs, while others use a lower percentage or assess it case by case.

How the Debt-to-Income Cap Affects Investment Loan Approvals

From February this year, each bank can approve no more than 20 per cent of new investor loans at a debt-to-income ratio of 6 times or greater. The cap applies separately to each lender's investor portfolio and only affects new lending. If your total debt (including your existing home loan and the proposed investment loan) is more than six times your gross income, you fall into that restricted category.

For a nurse earning $100,000, a DTI of 6 times means total borrowing of $600,000. If you already have a $450,000 home loan and want to borrow another $200,000 for an investment property, your total debt would be $650,000, putting you over the threshold. Some lenders hit their 20 per cent allocation early in the month and will decline applications that would otherwise be serviceable. Others manage their allocation more conservatively and remain open throughout the month.

The practical outcome is that loan structure and lender selection matter more than they did previously. Splitting your lending across two lenders, or refinancing your existing home loan to release equity and reduce the new borrowing amount, can bring your DTI below the threshold. We also see nurses using a partner's income to support the application where both parties will hold the investment property jointly, which spreads the debt across a higher combined income base. Timing your application and knowing which lenders still have capacity under the cap is part of the process now.

Deposit and LMI Considerations for Investment Property Finance

Most lenders require a higher deposit for investment property loans compared to owner-occupied lending. An 80 per cent LVR is the standard threshold to avoid Lenders Mortgage Insurance on an investment loan, meaning you need a 20 per cent deposit plus costs. If you are buying a property for $500,000, you need at least $100,000 in deposit and another $15,000 to $20,000 for stamp duty, legal fees, and other settlement costs.

LMI is available on investment loans, but the premium is higher than for owner-occupied loans at the same LVR, and fewer lenders offer LMI above 90 per cent LVR for investment purposes. Some lenders cap investment loans at 90 per cent LVR even with LMI, while others will lend up to 95 per cent in limited circumstances. For nurses and midwives with access to professional LMI waivers, those waivers typically apply only to owner-occupied lending, not investment loans. That means even if you previously purchased your own home with a 5 per cent deposit and no LMI, you will likely need a full 20 per cent deposit when buying an investment property, or accept the cost of LMI if you borrow above 80 per cent LVR.

One approach that works in our experience is leveraging equity in your existing home to fund the deposit for the investment property. If your home has increased in value since purchase and you have paid down the loan, you may be able to access that equity without selling. Equity release allows you to increase the loan on your existing property and use the funds as a deposit for the investment purchase. This keeps you in the market without needing to save a second deposit from scratch, although you need to factor the increased repayment on your home loan into your overall serviceability.

Negative Gearing Rules and the 1 July 2027 Change

For properties held before 7:30pm AEST on 12 May this year, the existing negative gearing rules continue to apply. Where your property expenses (including loan interest, property management fees, council rates, insurance, and repairs) exceed your rental income, the net rental loss can be offset against your salary and other assessable income, reducing your overall tax.

From 1 July next year, net rental losses on residential investment properties purchased on or after 12 May this year are quarantined. You can only offset those losses against other residential rental income, or carry them forward to offset future rental income or capital gains on residential property. You cannot offset them against your nursing salary. Properties that qualify as eligible new builds are exempt from the quarantine and can still be negatively geared under the existing rules. An eligible new build is a dwelling constructed on previously vacant land or a property where the number of dwellings increases, such as a duplex replacing a single house.

If you are considering an investment property purchase in the next 12 months, the quarantine applies unless you buy an eligible new build or settle before 30 June next year. The financial impact depends on your tax rate and the size of the expected loss. A nurse on a marginal tax rate of 32.5 per cent with a $10,000 annual rental loss would have previously received a tax benefit of around $3,250. Under the new rules, that benefit is deferred until you have rental income or a capital gain to offset it against, or until you sell the property. If you are selecting between an established property and a new build, the ability to offset losses immediately may influence the numbers, particularly in the first few years when interest costs are highest and rental income has not yet increased.

Interest-Only Investment Loans and Repayment Structure

Most investment property loans are structured as interest-only for an initial period, typically five years, after which the loan reverts to principal and interest repayments. Interest-only repayments are lower than principal and interest, which can help with short-term cash flow, particularly if the property is negatively geared. The interest portion of the repayment is still tax-deductible against rental income (or offset against other income under the existing negative gearing rules, or quarantined under the new rules).

Lenders assess interest-only loans at the same serviceability buffer as principal and interest loans, and they also assess your ability to meet the principal and interest repayment once the interest-only period ends. Under APRA's capital rules, interest-only loans and investment loans attract higher risk weights, which means they are more expensive for lenders to fund. That cost is often passed through in the form of a higher interest rate compared to owner-occupied principal and interest loans.

If you plan to hold the property long-term, paying down the principal over time reduces your debt and builds equity. If your strategy is to use rental income to cover costs and build wealth through capital growth, an interest-only structure might suit the early years, particularly if your cash flow is tight. You can find more detail on how interest-only loans work and when they make sense in the interest-only loans section of the site. The decision comes down to your cash flow, your tax position, and whether you are prioritising debt reduction or portfolio growth.

Capital Gains Tax Changes from 1 July Next Year

Under new legislation that received Royal Assent in June this year, the 50 per cent CGT discount for individuals will be replaced from 1 July next year with cost base indexation and a minimum 30 per cent tax rate on real capital gains. For properties owned before 1 July next year and sold after that date, gains are split between the old rules (50 per cent discount) for the portion accruing before 1 July and the new rules (indexation and 30 per cent minimum rate) for the portion accruing after that date.

If you buy an investment property now and sell it in five or ten years, the capital gain will be calculated in two parts. You will need either a market valuation as at 1 July next year or you can apply an ATO apportionment formula to split the gain. For eligible new build properties, you can elect to use either the 50 per cent discount or the indexation method, whichever produces the lower tax.

The indexation method adjusts your cost base for inflation using the Consumer Price Index, so only the real gain (above inflation) is taxed. If inflation is low, indexation provides less benefit. The 30 per cent minimum rate applies regardless of your marginal tax rate, so if you are on the top marginal rate, the minimum may reduce your tax, but if you are on a lower marginal rate, the minimum may increase it. The change adds complexity to the hold versus sell decision and makes it harder to project after-tax returns over a long hold period. Investors receiving income support payments such as the Age Pension are exempt from the 30 per cent minimum rate in any year they receive the payment.

Choosing Between Variable and Fixed Rate Investment Loans

Variable rate investment loans allow you to make extra repayments, redraw funds (subject to lender terms), and often provide access to offset accounts. Fixed rate loans lock in your interest rate for a set period, typically one to five years, which provides repayment certainty but usually limits extra repayments and removes access to offset and redraw during the fixed term.

Rate discounts on investment loans are generally smaller than on owner-occupied loans, and the gap between variable and fixed rates moves with the broader market. Some lenders offer the same offset and redraw features on investment loans as they do on owner-occupied lending, while others restrict or remove those features entirely. If you are planning to make extra repayments or want the flexibility to access equity later without refinancing, a variable rate product with full offset and redraw is usually the right fit. If you are concerned about rate rises and want to lock in your repayment and tax deduction for budgeting purposes, a fixed rate or partial fix might suit, particularly if you do not intend to pay ahead.

We regularly see nurses split their investment loan between fixed and variable portions to balance certainty and flexibility. One approach is to fix 50 to 70 per cent of the loan and leave the remainder variable, so you have some protection against rate increases and still retain access to offset and the ability to make extra repayments on the variable portion. If you already hold an investment loan and are considering your options, you can read more about refinancing on the investment loan refinancing page.
