Negative Gearing and Investment Loans: What Property Investors Need to Know
Key Takeaways
Negative gearing means your property runs at a loss; the tax deduction only refunds your marginal rate on that loss, so the after-tax shortfall is the real weekly cost you fund yourself.
That ongoing shortfall usually reduces how much you can borrow next, though some lenders add back part of the benefit in their serviceability sums.
Loan structure matters: interest-only eases cash flow and keeps deductible interest high, while an offset lowers interest but also lowers your deduction.
The strategy only works if capital growth outpaces your accumulated losses, so build in a buffer for rate rises, vacancies, and repairs.
Negative gearing is one of the most talked-about ideas in Australian property, and one of the most misunderstood. With interest rates higher than they were a few years ago, the gap between what an investment property earns in rent and what it costs to hold has widened for many investors, which means more properties are negatively geared than before. That makes it more important than ever to understand what negative gearing actually does to your cash flow, your tax, and your ability to borrow, rather than treating it as a reason to invest on its own.
If you are weighing up an investment purchase, the real questions are practical. How much will the property cost you out of pocket each week after the tax benefit, can you comfortably carry that shortfall if rates rise or the property sits empty, and how does the loss affect what you can borrow next? Getting clear on these turns negative gearing from a buzzword into a number you can actually plan around.
This article explains how negative gearing works, why a tax saving is still a real cash-flow cost, how lenders assess negatively geared investors, and how loan structure can make the strategy easier or harder to carry. The aim is to give you a grounded, loan-first picture before you commit.
The quick answer: what negative gearing means for your loan
Negative gearing simply means your investment property costs more to hold than it earns in rent, creating a loss. That loss can usually be used to reduce your taxable income, which softens the blow at tax time, but it does not erase it. You still need the cash flow to cover the shortfall every month, and lenders factor that ongoing shortfall into how much you can borrow.
So the strategy only makes sense if you can carry the after-tax loss comfortably and you expect the property's value to grow by more than those losses cost you over time. The tax benefit is a help along the way, not the point of the exercise.
What negative gearing is
Gearing just means borrowing to invest. A property is negatively geared when the deductible costs of owning it, mainly the loan interest plus rates, insurance, management fees, and maintenance, add up to more than the rent it brings in. That net loss can generally be offset against your other income, such as your salary, reducing the tax you pay.
The appeal is that the tax system shares part of the loss with you, and that you are holding an asset you hope will grow in value. The catch is that you are deliberately running the property at a loss in the meantime, and you have to fund that loss from your own pocket until the property is sold or the rent catches up to the costs.
Negative gearing versus positive gearing
It helps to see negative gearing alongside its opposite, because the right choice depends on your income, your cash flow, and what you want the property to do. The two sit at different ends of the same scale.
A negatively geared property runs at a loss, so it costs you money to hold, but the loss reduces your taxable income and you are betting on capital growth.
A positively geared property earns more in rent than it costs, so it puts cash in your pocket, though that surplus is taxable income.
A neutrally geared property sits roughly in the middle, with rent and costs close to even.
Neither is automatically better. A positively geared property is easier on cash flow and can even support your borrowing capacity, while a negatively geared property may suit a higher-income investor focused on long-term growth who can comfortably fund the shortfall.
Why a tax saving is still a cash-flow loss
This is the single most important thing to understand, and it is where the "free money" myth falls apart. A tax deduction does not refund your whole loss; it only reduces your tax by your marginal rate applied to that loss. You are still out of pocket for the rest.
Consider a property renting at $500 a week, around $26,000 a year, with total holding costs of $40,000 a year once interest and expenses are added up. The pre-tax loss is $14,000. If your marginal tax rate including the Medicare levy were, say, 39%, your tax saving would be roughly $5,460. That still leaves an after-tax shortfall of about $8,540 a year, or close to $164 a week, that you fund yourself.
That weekly figure is the number that matters. It is what the property genuinely costs you to hold after the tax benefit, and it is what you need to be confident you can cover month after month. The marginal rate used here is illustrative only; your actual rate depends on your income, and your accountant is the right person to confirm it.
How lenders assess negatively geared investors
Negative gearing does not just affect your tax; it affects what you can borrow, and this is the angle that often gets overlooked. Lenders look closely at whether you can carry the shortfall, and several parts of their assessment pull in different directions.
How rental income is counted
Lenders rarely count the full rent. They typically use around 80% of the gross rental income, holding back the rest for vacancies, management fees, rates, and maintenance. So the income side of your property is assessed more conservatively than the headline rent suggests, which widens the gap the lender sees.
How the assessment buffer applies
The Australian Prudential Regulation Authority (APRA) expects lenders to test your repayments at the actual rate plus a buffer, currently 3 percentage points. This applies across all your loans, so a negatively geared investor is stress-tested as though rates were meaningfully higher, on top of already carrying a shortfall. The more leveraged you are, the harder this bites.
How the shortfall affects future borrowing
Because the property runs at a loss, that ongoing shortfall reduces the income available to service any further borrowing. In practical terms, a negatively geared property can lower how much you can borrow for your next purchase, which is why investors building a portfolio need to plan their borrowing capacity, not just their tax position.
How negative gearing add-backs vary by lender
Some lenders add back part of the negative gearing tax benefit when calculating your serviceability, which can lift your borrowing capacity, while others take a more conservative view and do not. This is one of the areas where lender policy differs most, so matching your situation to a lender whose approach suits you can change what is possible.
Loan structure: interest-only, P&I, offset and split loans
How you structure the loan has a direct effect on your cash flow and on the size of your deductible interest, so it is worth thinking through rather than accepting the default. A few choices come up for most investors.
Principal and Interest (P&I) repayments pay down the loan over time, building equity but costing more each month. Interest-Only (IO) repayments cover just the interest for a set period, usually up to five years, which lowers repayments and, because the whole repayment is interest, keeps the deductible portion high. Many negatively geared investors choose interest-only to ease cash flow while they hold the property, though that is a decision to confirm with your accountant rather than a given.
The trade-offs are real. During an interest-only period, the balance does not reduce, and when it ends the loan reverts to principal and interest over the remaining term, which means higher repayments from that point. An offset account can also help: holding spare cash against the loan reduces the interest you pay, though it also reduces your deductible interest, so the benefit is not as one-sided as it first appears. A split loan, part fixed and part variable, can add repayment certainty over part of the debt. None of these is right or wrong on its own; they depend on your cash flow and your plan.
Costs investors need to include
An honest gearing calculation depends on counting every cost, not just the loan interest. Underestimating the holding costs is a common reason a property turns out to cost more than expected.
Loan interest is usually the highest single cost.
Property management fees, commonly around 7% to 8% of rent if you use an agent.
Landlord insurance and building insurance.
Council rates, water charges, and strata or body corporate fees where they apply.
Repairs and ongoing maintenance.
Depreciation, a non-cash deduction that can reduce your taxable income without affecting your weekly cash flow.
Depreciation is worth a mention because it works differently from the others. It reflects the declining value of the building and fittings rather than money leaving your account, so it can improve your tax position without adding to your cash shortfall. A quantity surveyor's depreciation schedule and your accountant's guidance are the way to get this right.
The risks that decide whether it works
Negative gearing leans heavily on assumptions about rates, tenancy, and growth, and the strategy only works if those assumptions hold up over time. It pays to look honestly at what could go wrong.
Rate rises push up your largest cost, widening the loss and the weekly shortfall you fund.
Vacancies remove rent entirely for a period, while the costs keep running.
Unexpected repairs can hit your cash flow hard in a single year.
Weak capital growth is the big one: if the property does not grow in value by more than your accumulated after-tax losses, the strategy has cost you money overall.
It is also worth knowing that negative gearing is a feature of current tax rules, and tax policy can change over time, so confirming the current position with your accountant before you rely on it is sensible.
Real borrower scenarios
How negative gearing plays out depends on your income, equity, and cash flow. These four situations show the range.
First-time investor using home equity
A couple uses the usable equity in their home as the deposit on an investment unit. The property is negatively geared by around $150 a week after tax. The key question is not the tax benefit but whether they can comfortably absorb that $150 every week, including if rates rise, before they commit.
High-income investor focused on growth
A higher-income investor deliberately chooses a negatively geared property in a growth area. Their marginal tax rate means the deduction is more valuable to them, and their income comfortably covers the shortfall. For them, the strategy is about long-term capital growth, with the tax benefit as a secondary help.
Investor with tight cash flow
An investor is drawn to the tax savings but has limited spare cash each month. Once the after-tax shortfall and a buffer for rate rises and vacancies are factored in, the property would stretch them too far. A positively or neutrally geared property, or a smaller purchase, may suit their situation better.
Refinancer moving from interest-only to P&I
An investor's interest-only period is ending, and their repayments are about to jump as the loan reverts to principal and interest. They review their options early, comparing lenders and considering whether to extend interest-only, switch to principal and interest, or restructure, so the change does not catch their cash flow off guard.
When negative gearing may suit an investor
Negative gearing tends to fit when your income and cash flow can carry the loss without strain, and your focus is long-term growth rather than immediate income. It is most likely to suit you when several of these are true.
Your income comfortably covers the after-tax shortfall, with a buffer to spare.
Your marginal tax rate makes the deduction genuinely meaningful.
You are investing for capital growth over a long horizon, not short-term cash flow.
You have a cash reserve for rate rises, vacancies, and repairs.
You understand the strategy depends on growth outpacing the losses.
When it may be too risky
For some investors, the shortfall and the reliance on growth make negative gearing more strain than it is worth. It may not suit you when several of these apply.
Covering the weekly shortfall would leave you without a financial buffer.
A modest rate rise would push the property beyond what you can comfortably fund.
You are relying mainly on the tax benefit to justify the purchase.
You need the property to support your cash flow rather than drain it.
Your income is uncertain or likely to fall.
How a broker and an accountant work together
Negative gearing sits right at the intersection of lending and tax, which is why the two professionals complement each other. The accountant handles the tax side, and the broker handles the borrowing and structure side, and the best outcomes come when they are working from the same plan.
In practice, a broker can model your borrowing capacity across all your loans, work out your usable equity, and show you the real after-tax shortfall before you buy, so you know what the property costs you each week. They can compare lenders whose rental income and negative gearing policies suit your situation, and structure the loan, including any interest-only period or offset, to support your cash flow. Your accountant then confirms the deductions, depreciation, and your marginal tax position. Speaking to both before you commit means your strategy is grounded in what a lender will actually approve and what the tax rules genuinely deliver.
If you are trying to work out whether a negatively geared property is manageable in real cash-flow terms, speaking with a mortgage broker in Albury & Wodonga can help you model the lending side before you commit. This is especially useful when rental income, usable equity, interest-only options, and lender serviceability rules all affect whether the investment loan is realistic.
Frequently Asked Questions (FAQs)
Is negative gearing the same as losing money?
In cash-flow terms, yes, in the short run. A negatively geared property costs you more to hold than it earns, and the tax deduction only reduces part of that loss, not all of it. The strategy aims to come out ahead through capital growth over time, so it relies on the property's value rising by more than the losses cost you.
How does negative gearing reduce tax?
The net loss from the property can generally be offset against your other income, such as your salary, lowering your taxable income. The actual saving is your marginal tax rate applied to the loss, so a higher income tends to make the deduction more valuable. Your accountant can confirm how it applies to your circumstances.
Does negative gearing improve or reduce borrowing capacity?
Usually it reduces it, because the ongoing shortfall lowers the income available to service further borrowing. That said, some lenders add back part of the negative gearing benefit in their serviceability calculations, which can help. Because this varies between lenders, it is an area where choosing the right one matters.
Should negatively geared investors choose interest-only?
Many do, because interest-only repayments lower the monthly cost and keep the deductible interest high, which eases cash flow while holding the property. The trade-offs are that the balance does not reduce during the interest-only period and repayments rise when it ends. Whether it suits you depends on your cash flow and plan, and is worth confirming with your accountant.
Can I use an offset account with an investment loan?
Yes. An offset account holds spare cash against the loan and reduces the interest you pay while keeping the funds available. The subtlety for investors is that reducing your interest also reduces your deductible interest, so the benefit is not as straightforward as on an owner-occupied loan. It is a useful tool, but worth structuring with advice.
What happens if interest rates rise?
Interest is usually an investor's highest cost, so a rate rise widens the loss and increases the weekly shortfall you fund yourself. This is why building a buffer for higher rates into your numbers, rather than assuming rates stay where they are, is an important part of carrying a negatively geared property safely.
Should I speak to a broker or an accountant first?
It is worth speaking to both, ideally before you buy. A broker can tell you what you can borrow and what the property will cost you in cash flow, while an accountant can confirm the deductions and your tax position. Together, they give you the full picture, so neither the lending nor the tax side comes as a surprise later.
The Bottom Line
Negative gearing is not free money, and it is not a reason to invest on its own. It means deliberately holding a property at a loss, where the tax system covers part of that loss and you fund the rest, in the expectation that capital growth will more than make up for it over time. The number that matters most is your real after-tax shortfall, and whether you can carry it comfortably through rate rises and vacancies.
Before you commit, work out that weekly cost, build in a buffer, and check how the shortfall affects what you can borrow next. Pair a broker's view of your borrowing and cash flow with an accountant's view of your tax, and you move from chasing a deduction to making a decision you can actually live with.
