Renting vs Buying: The Real Numbers for Australian Families

Short Answer

There's no universal right answer — it comes down to your family's timeline, finances, and priorities. Buying builds long-term wealth through equity but comes with big upfront and ongoing costs. Renting gives you flexibility and predictable bills but doesn't build assets. For most families, the numbers favour buying if you can stay put for at least 5–7 years.

The Real Numbers: A Side-by-Side Look

Let's compare renting vs buying a 3-bedroom family home in a middle-ring suburb of a capital city — think $800,000 to buy, or $650/week to rent.

At first glance, buying looks $30,000 more expensive per year. But here's what the rental number doesn't show: equity.

What the Monthly Repayment Actually Buys You

With a $720,000 mortgage at 6.2% over 30 years, your first-year repayments total about $58,848. Of that, roughly $44,000 goes to interest and $14,800 pays down the loan principal.

That $14,800 isn't "spent" — it's forced savings building your ownership stake. Over 5 years, that principal grows to about $85,000 (assuming no price change). If the property grows at a modest 3% per year, you'd have an extra $127,000 in capital gains on top.

After 5 years of renting at $650/week, you've paid about $169,000 in rent with zero equity to show for it.

That's the fundamental difference: every rent payment is gone forever; part of every mortgage payment stays yours.

When Renting Makes More Sense

Renting isn't "throwing money away" — it's the smarter call in these situations:

• You might move in the next 3–5 years. Stamp duty and selling costs (agent fees, marketing) can easily eat $40,000–$50,000. That wipes out any price growth in a short holding period.
• You're not sure about the school zone yet. Renting lets you test a suburb — commute, neighbours, schools — before committing six figures.
• Your deposit isn't there yet. Rushing in with a 5% deposit means paying thousands in LMI — money you never get back.
• You value flexibility. Job changes, growing family, or a year of travel — renting gives you options buying doesn't.

When Buying Is Worth It

Buying starts to pull ahead financially when:

• You'll stay put for 7+ years. This gives equity enough time to build and transaction costs enough time to amortise.
• You have a 20% deposit. Skipping LMI saves you $15,000–$25,000.
• You want stability for your kids. No landlord can give you notice to vacate. Your kids stay in the same school, with the same friends.
• You're okay with the responsibility. Owning means you fix the hot water system. Some people hate that; others love the control.

First Home Buyer Help: What's Available

If you're a first home buyer, the government has several schemes that can tilt the maths toward buying:

These schemes can knock $30,000–$50,000 off the upfront cost of buying — enough to flip the rent-vs-buy equation for many families.

The Third Path: Rentvesting

There's a middle ground growing in popularity: rentvesting. You rent where you want to live (close to work, good schools) and buy an investment property somewhere more affordable. You get the tax benefits of property investment — negative gearing, depreciation — while keeping the lifestyle flexibility of renting.

It's not for everyone — you need to be comfortable being a landlord — but it's worth understanding as an option, especially if your dream suburb is out of reach for buying but affordable to rent.

What Would Ava Do?

Here's my honest take as a CPA and a mum: the best financial decision is the one that lets you sleep at night.

I've seen families stretch themselves paper-thin to buy, then spend years stressed about every rate rise. I've also seen families rent happily for a decade, investing the difference in ETFs and building wealth a different way. Both paths work — they just work differently.

Run the numbers for your specific situation. Think about what matters most to your family right now — and what will matter in 5 years. There's no prize for owning a house if it makes you miserable.

A simple starting point: If you can afford the deposit and plan to stay 7+ years, buying usually wins. If you're not sure where you'll be in 3 years, keep renting and keep building your deposit. Either way, you're making a thoughtful choice — and that's what counts.
