How Much Deposit Do You Need to Buy a Home?

Most buyers don’t need a 20% deposit to buy a home. Depending on your situation, you may be able to purchase with as little as 5–10%, especially if you’re a first home buyer, qualify for a government guarantee, or use a family guarantor.

What matters most isn’t just the deposit amount, but also how it’s sourced, whether it counts as genuine savings, and how the loan is structured to avoid unnecessary costs such as LMI.

This guide explains:

  • The minimum deposit lenders accept
  • How low-deposit home loans really work
  • When genuine savings are required
  • Smarter ways to buy sooner without over-stretching

First Step – Speak With a Mortgage Broker

Standard Deposit Requirements in Australia

Traditionally, lenders prefer a 20% deposit of the property’s purchase price.

This allows you to:

  • Avoid Lenders Mortgage Insurance (LMI)
  • Access sharper interest rates
  • Have more lender choice

However, most first home buyers do not start with 20%, and that’s where alternative pathways come in.

Buying With a 10% Deposit

With a 10% deposit, many lenders will still approve a home loan, but:

This option often suits buyers with stable incomes and solid savings histories who want to enter the market sooner.

Buying With a 5% Deposit (Low Deposit Options)

Many first home buyers can purchase with as little as 5% deposit, provided they meet additional criteria.

Common pathways include:

With a 5% deposit:

  • LMI is often reduced or waived under guarantees
  • Lender policy becomes critical
  • Genuine savings rules are closely assessed

This is where speaking with a broker matters, as not all lenders treat 5% deposits the same way.

What About Costs Outside the Deposit?

Your deposit is only part of the picture.

You also need to allow for:

Some first home buyers mistakenly use all their savings as a deposit and forget about these costs, which can cause issues later.

What Is Genuine Savings and Why Does It Matter?

Many lenders require genuine savings, especially when your deposit is under 20%.

Genuine savings usually mean:

  • Funds saved gradually over at least 3–6 months
  • Money earned and retained, not borrowed
  • Evidence you can manage money consistently

Not all deposits qualify automatically.

Examples that may not count:

  • Gifts from family
  • Tax refunds or bonuses held short-term
  • Borrowed funds

Can First Home Buyer Grants Be Used as a Deposit?

This is a common misunderstanding.

In most cases:

Grants work best when combined with:

  • Genuine savings
  • A guarantee scheme
  • Or a guarantor structure

Using a Family Guarantor Instead of a Cash Deposit

Some buyers use a family guarantor to reduce or remove the cash deposit requirement.

This can:

  • Remove the need for genuine savings
  • Eliminate or reduce LMI
  • Allow earlier entry into the market

However, guarantor loans must be structured carefully to protect everyone involved.

How Much Deposit Should You Aim For?

There’s no single “right” number.

As a guide:

  • 5%: Entry-level with support schemes
  • 10%: More lender choice, lower risk
  • 20%+: Strong position, no LMI

The best deposit is the one that:

  • Fits your cash flow
  • Leaves a safety buffer
  • Doesn’t delay your plans unnecessarily
