In short
- Property investing means owning land and buildings that someone else lives in, so the property earns for you.
- It earns in two ways: rent, paid as you go, and growth, the rise in what the property is worth over time.
- It costs money to hold: interest, rates, insurance, repairs and management.
- Run it like a small business and the numbers, not the noise, tell you whether it works for you.
You have probably heard someone say they “have an investment property” and wondered how that actually makes money. It is simpler than it sounds, and you can see it clearly once the parts are laid out.
What property investing means
Property investing means you own land and buildings, and someone else lives in them and pays you rent. The property is not your home. It is there to earn for you.
Treat it like a small business. It has income, costs, a loan, a tax return and a customer, your tenant. For tax, though, most owners are investors, not in a business. People who treat it that way tend to sleep better, because they know their numbers.
The two ways it earns
The first way is rent. Your tenant pays you each week or each month. Rent pays the costs of holding the property, and sometimes leaves money over.
The second way is growth. Over time, the value of the property can rise. Most of that rise sits in the land, because land is scarce and buildings wear out. You do not get growth in your hand each week. You get it when you sell, or you can borrow against it to buy again.
What it costs to hold
Holding a property costs money every week. You pay interest on the loan, council rates, insurance, repairs and, if you use one, a property manager. Before you buy, it pays to know what the property will cost you each week after the rent comes in.
When the rent covers every cost and leaves money over, people call it “positively geared”. When the costs are more than the rent, it is “negatively geared”, and you make up the gap from your own pocket while you wait for growth.
How the tax side works
Rent is income you declare in your tax return.
The costs of holding a rental can generally come off that income. What matters is what the borrowed money is used for, not what the loan is secured on. Money borrowed against a rental and used for a holiday gives no deduction. Money borrowed against your home and used to buy or build a rental can.
The tax law also lets you claim part of what the building cost to build, each year. For a home whose building started on or after 16 September 1987, you can claim 2.5% of the construction cost each year, over 40 years. The base is what the building cost to build, not what you paid for the property, and never the land.
Fittings work differently. Plant and equipment in a home built for you, or bought new from the builder before anyone has lived in it, can be claimed. Second-hand plant in a rental home cannot.
If the property makes a loss, the rules changed this year. Under the law today, from the 2027-28 income year a loss on a home bought after 7.30 pm on 12 May 2026 can’t be taken off your other income; it carries forward against later rent or gains on homes. The Tax Reform No. 3 Bill 2026, passed by the House of Representatives on 29 October 2026 and not yet law, would exempt a newly built home.
When you sell, any gain is a capital gain. Today, if you are an Australian resident and have held the property for at least 12 months, only half of the gain is taxed. From 1 July 2027 that discount is replaced, for gains from that date, by indexing the cost of the property to inflation. New homes keep a choice, but what counts as new is not yet set.
| Part | What it is | When you get it or pay | How tax sees it |
|---|---|---|---|
| Rent | Money your tenant pays | Each week or month | Income you declare |
| Growth | Rise in what it is worth, mostly land | When you sell, or as equity to borrow on | A capital gain when you sell |
| Costs | Interest, rates, insurance, repairs, management | Each week, month or year | Generally come off the rent income |
In words: rent is the money your tenant pays, which you get each week or each month and declare as income. Growth is the rise in what the property is worth, mostly in the land, which you get when you sell or use as equity to borrow against, and which is a capital gain when you sell. Costs are interest, rates, insurance, repairs and management, which you pay each week, month or year, and which generally come off your rent income.
What it takes to start
Most people buy with a loan. Lenders usually charge lenders mortgage insurance when the loan is more than 80% of the property’s value. That is the lenders’ practice, not a law, and some lenders waive it for some professions.
So the first questions are about you, not the property: how much you can put in, how much you can borrow, and what the property will cost you each week after rent.
What I look for
My own view is that the properties worth owning have strong cash flow, room for the value to lift, or something outside the box that can give more than the average investment. That’s my view; yours may differ, and the choice is always yours.
