Negative Gearing Explained

Oct 2025

If you spend time around people who have an investment property, you will hear people say they want a property that is ‘negatively geared’. The thinking goes that a tax deduction makes the numbers work. Sometimes it does. Sometimes it doesn’t. The real game is your after-tax return and whether the asset will grow strongly enough to justify any short-term pain. 

Quick refresher 

Negative gearing is when your total property costs are higher than the rent you receive. That loss reduces your taxable income, which lowers the tax you pay. The idea only helps if the long-term growth of the property more than offsets the cash you are tipping in each year. 

A simple example with real numbers 

Purchase price: $700,000 
Annual rent: $30,000 
Interest and other costs: $40,000 
Cash result: a loss of $10,000 

If you earn $200,000 a year, that $10,000 loss reduces your taxable income to $190,000. At a marginal tax rate of 45 percent, that saves about $4,500 in tax. You still spent $10,000 that year to get $4,500 back, so you are out of pocket $5,500. You are betting that capital growth will more than cover that gap. 

The upside most people point to 

  • Tax benefit for higher-income earners 
  • Ability to hold a high-growth asset in a quality area that would otherwise be hard to carry 
  • Potential for long-term compounding if the asset quality is high and you can ride the ups and downs 

The downside that trips people up 

  • Cash-flow strain when interest lifts or the property is vacant 
  • Market risk if growth is slower than expected or if you pay too much going in 
  • Tax is not profit and a refund does not turn a loss into a win 

How to decide using the Finhem-style sense check 

Ask three questions and be honest with the answers. 

  1. Would I still buy this asset if there were no tax benefit 
  1. Can I comfortably carry the worst-case cash flow for at least a few years 
  1. Is this a quality asset that has genuine drivers of growth such as scarcity, school zones, and infrastructure 

Optimising the strategy if it does stack up 

Start by stress testing your numbers. Model a few interest rate rises and a few months without rent to see how much breathing room you really have. 

Next, get your loan structure right. This is where a mortgage broker can make a real difference. The way you set up your loans, offsets, and repayments will have more impact on your cash flow and borrowing power than almost anything else. 

Consider building some flexibility into your setup. An offset account or redraw facility can act as a buffer when things get tight and help you manage cash flow without touching savings or taking on more debt. 

Finally, keep an eye on your lending strategy each year. As rates move and your income or rent changes, you might be able to refinance, adjust your structure or pay down debt faster to get closer to a neutral or positive position. 

Smart moves for investors 

Focus on the fundamentals, not just the tax outcome. A property that performs well over time will always deliver better results than one bought purely for a deduction. 

Understand your true costs upfront. Factor in purchase costs, maintenance, insurance and any upcoming repairs, so your cash flow picture is realistic from day one. 

Base your numbers on conservative assumptions. It is better to be pleasantly surprised when rent is higher or expenses lower than the other way around. 

Look for quality, not hype. The best long-term results come from well-located properties with strong demand drivers, not from chasing what is hot right now. 

Our take 

Negative gearing is not a strategy in its own right. It is a by-product of choosing a growth asset and deciding to wear short-term losses to capture long-term upside. It can work for higher-income earners with strong borrowing capacity and the temperament to ride through cash-flow swings. 

At Finhem we help clients understand how their lending decisions shape their broader financial picture. Whether you are buying your first investment property or expanding your portfolio, getting the loan structure right from the start can make a big difference to your cash flow, flexibility and future options.
