Negative gearing is when your investment property costs more to own than it earns in rent. So you have to cover the shortfall.
If the property rents for $25,000 a year but costs $30,000 to run, it’s negatively geared by $5,000. You need to “top up” the difference from your own pocket.
Most people get into property investment thinking: “Great, the tenant will pay off my mortgage.”
That might be true. But there are other costs investors need to think about. That includes rates, maintenance, insurance and yes, your mortgage.
In this article, you’ll learn what negative gearing is, why it happens, and how investors can still make money from a negatively geared property.
| Annual rent | Annual expenses | Cashflow | What this means | |
| Positive gearing | $25,000 | $20,000 | +$5,000 | Property pays you $5k per year |
| Negative gearing | $25,000 | $30,000 | -$5,000 | You contribute $5k per year |
When a negatively geared property costs the investor money each week, the investor needs to ‘top up’ the property.
At the time of writing, most investors pay a top up of $200-$350 a week.
That just means that investors transfer money into their investment property account. That’s to make sure there is enough money to cover all the costs.
If your rent is $600 per week, but your mortgage, rates, and other costs add up to $850 per week, you’ll need to top up $250 per week.
Every investor’s top-up is different. That’s because no two properties (or mortgages) are the same. Your weekly top-up depends on how much rent the property earns and how much it costs to run.
The factors that influence your top-up include:
Generally, if you have a bigger mortgage, you pay more interest to the bank, so your cashflow is lower.
That’s why investors have bigger top-ups when they use the “No Cash Needed Method”. That’s where you borrow all the money to buy an investment property.
If you contribute a deposit, you’re not borrowing as much money. That makes your mortgage repayments go down. So your top-up is lower.
Top-ups can change. So, it’s important to stress-test your numbers before buying a property. That includes running a scenario where interest rates go up.
Some investors wonder: “If my property is negatively-geared, how do I make money?”
Property investors often make most of their money through the property going up in value. That’s called the capital gain.
Properties are worth a lot of money. So, a small increase in the value of the asset (in percentage terms) can mean you make a lot of money.
For instance, if a $1 million property increases in value by 10%, that means the investor makes $100,000 in capital gains.
So while an investor might top up a property each week, this cash input is often outweighed by the increase in the property’s value.
For instance, here is an example of a $650,000 property that is negatively geared by $100 a week. In this example the property increases in value by 5% each year.
See how the increase in the value of the property per week is much larger than the amount the investor is putting in to top it up.
So, put simply, property investors can still build their wealth through the property increasing in value.
In an ideal world, investors could buy a property that:
The reality is that you often can’t get all 3 in the same property.
If you are following a buy-and-hold strategy based on New Builds, then you often need to choose two of the following:
But you often can’t have all three at once.

Here’s how the trade-off works:
| If you choose: | |
| Capital Growth + No Deposit | You’ll likely need to top up the cashflow (negative gearing) |
| Capital Growth + Positive Cashflow | You’ll likely need to contribute a deposit |
| Positive Cashflow + No Deposit | You’ll likely sacrifice some capital growth |
This simple model can help you think through the trade-offs you’re choosing your next property investment.
So if you buy a high-growth property using 100% lending, you’ll typically need to top-up the property.
That’s not because the property is “bad.” It’s because of the choices you’ve made.
Here are the 6 reasons your property might be negatively geared:
Rents tend to rise over time, historically around 4 – 5% per year.
If you hold a property long enough, rents often go up faster than all your costs. But in the early years, growth properties often require a top-up.
If your rent hasn’t kept up with the market, you might be collecting less income than you could be. This makes your cashflow worse.
This is one of the most common issues investors overlook.
If you pay principal and interest on your mortgage, your immediate cash flow will be lower than if you used an interest-only mortgage.
If you’re paying down debt on your investment property, your cashflow will look worse. Even though you’re building equity faster.
Apartments and townhouses can have rising body corporate fees, especially in older buildings.
Large maintenance costs or underfunded long-term maintenance plans can significantly increase annual expenses.
Some investors deliberately take out more loans against their investment property. That could be to have less debt against their family home.
This can make the investment property negatively geared on paper. But it could improve their overall household cashflow.
Growth properties typically prioritise capital gains over cashflow.
They often have lower yields, which means they’re more likely to be negatively geared.
Negative-gearing isn’t automatically good or bad. It’s just a fact of life.
And it should be said that not every negatively-geared property is a good investment.
Whether it makes sense, or not, for you depends on your strategy, income, and long-term goals.
Here’s when it may, and may not, be the right fit.
| Negative-gearing may make sense if… | Negative-gearing may NOT make sense if… |
You want a passive, hands off strategy You’re focused on long-term capital growth You have the income to comfortably top up You’re building a small portfolio You’re comfortable buying properties with a load of debt | You prefer renovating or actively adding value You prioritise strong monthly cashflow Cashflow is tight or unpredictable You’re planning to buy 10+ properties You prefer lower debt and lower risk |
So it really depends on what type of investor you ask.
Investors who favour negative gearing often see it as a long-term play.
They’re comfortable topping up $100–$150 per week. That’s because they believe the combination of leverage and capital growth can generate strong overall returns.
On the other hand, renovation-focused investors often aim to eliminate top-ups entirely.
If they can increase rent through improvements, they’d rather hold a property that pays for itself. Especially once they own multiple properties where weekly shortfalls quickly add up.
In the past, negative-gearing could reduce the tax you paid on your personal income.
Let’s say your property made a $5,000 loss and you earned $100,000 in salary. That loss could reduce your taxable income to $95,000.
That meant you could get a refund on some of the tax you’d already paid from your job.
On those numbers an investor might get a $1,650 tax refund. That’s based on a 33% tax rate.
But that changed in 2019.
Today, rental losses are ring-fenced. That means you can’t use property losses to reduce the tax you pay on your salary, business income, or dividends.
Let’s say:
You might think those cancel each other out. But they don’t.
You still pay tax on the $10,000 dividend income. The property loss can’t offset it.
Instead, that $10,000 rental loss is carried forward.
If, in future years, your property becomes profitable, you can use those carried-forward losses first. They save you tax on those future property profits.
So while you don’t get an immediate tax refund anymore, the losses aren’t wasted. They’re deferred.
Ring-fencing means negative gearing is now primarily a cashflow decision, not a tax strategy.
You won’t get an immediate tax refund to soften the shortfall. You need to be comfortable funding the top-up yourself.
The tax benefit may come later … but not today.
Not every property should (or will) be negatively geared.
Whether it makes sense depends on what you’re trying to achieve.
If your goal is to grow wealth using leverage and take a buy-and-hold approach, negative-gearing is often part of the strategy.
If your goal is stronger cashflow and self-sufficiency, then you’ll need to adjust the strategy. That’s done by focusing on yield, renovating, or contributing a deposit.
At the end of the day, every property investment requires something from you. There’s no universally “right” approach.
The better question is: What are you willing to contribute: cashflow, a cash deposit, or effort?
That answer determines whether negative gearing makes sense for you.
