How much deposit do I need to buy a house ?

How much deposit do I need to buy a house in Australia?

Hint: It might be less than you think.

When most people start thinking about buying a home, they assume they’ll need a 20% deposit—but that’s not always the case.

The truth is:

  • You might only need 5% of the purchase price
  • Some buyers get in with as little as 2% (with the right government support)
  • And there are even ways to buy with no deposit saved if you have a guarantor

The key is understanding your options, the additional costs involved (like stamp duty and LMI), and putting together a plan that works for you.

What Is a Deposit—And Why Does It Matter?

Your deposit is the portion of the purchase price you contribute upfront. Most banks like to see a 20% deposit—but that’s not a strict rule.

First home buyers may be eligible to buy with as little as 5%, and some government-backed schemes (like the First Home Guarantee or the Family HomeGuarantee) reduce the barrier even further.

But there’s more to buying a home than just the deposit itself. You also need to budget for:

  • Stamp duty (unless you're exempt)
  • Government fees (like title transfer)
  • Lenders Mortgage Insurance (LMI), if you borrow over 80%- Legal or conveyancing costs

All of these make up your total contribution, the real amount you’ll need before you can settle on your dream home.

Real-Life Examples: What You’ll Actually Need

Let’s walk through a few realistic examples using Victorian costs. These will differ a bit by state, but the principles stay the same.

Scenario 1: Single Buyer Using the First Home Guarantee

⚠️A quick note on eligibility:Schemes like the First Home Guarantee or stamp duty exemptions depend on things like:

  • Your income
  • Whether you’ve owned property before
  • The value of the home you're buying

For example, in Victoria, the First Home Guarantee is generally available for properties under $600,000–$700,000, and for single applicants earning under$125,000 or couples under $200,000 combined.
