How Much Deposit Do You Need to Buy a Home in Australia?
The Truth About Home Loan Deposits
One of the most common questions asked by aspiring homeowners is:
“How much deposit do I actually need to buy a home?”
Many Australians believe they need a 20% deposit before they can purchase a property. While a 20% deposit can provide advantages, it’s not always a requirement.
Depending on your financial circumstances, lender policies, and eligibility for government assistance schemes, you may be able to buy a home with a smaller deposit.
In this guide, we’ll explain how home loan deposits work, the benefits of different deposit sizes, additional buying costs to consider, and strategies to help you enter the property market sooner.
What Is a Home Loan Deposit?
A deposit is the portion of the property’s purchase price that you contribute from your own funds.
The remainder is generally financed through a home loan.
Example
Property Purchase Price: $800,000
Deposit: $80,000
Home Loan: $720,000
In this example, the borrower contributes 10% of the purchase price and borrows the remaining 90%.
How Much Deposit Do Most Lenders Prefer?
Many lenders prefer borrowers to have a deposit of at least 20% of the property’s value.
Why?
A larger deposit:
- Reduces lender risk
- Improves borrowing strength
- May help avoid Lenders Mortgage Insurance (LMI)
- Creates more equity from day one
Example
| Property Value | 5% Deposit | 10% Deposit | 20% Deposit |
|---|---|---|---|
| $600,000 | $30,000 | $60,000 | $120,000 |
| $800,000 | $40,000 | $80,000 | $160,000 |
| $1,000,000 | $50,000 | $100,000 | $200,000 |
While 20% is often considered ideal, many buyers successfully enter the market with less.
Can You Buy a Home with a 5% Deposit?
In some cases, yes.
Many lenders offer home loans for eligible borrowers with deposits as low as 5%.
For example:
Property Value: $700,000
Deposit (5%): $35,000
Loan Amount: $665,000
However, borrowers with smaller deposits may need to pay Lenders Mortgage Insurance (LMI) unless they qualify for certain government programs.
Understanding Loan-to-Value Ratio (LVR)
When assessing a home loan application, lenders often look at the Loan-to-Value Ratio (LVR).
LVR measures how much you’re borrowing compared to the property’s value.
Formula
Loan Amount ÷ Property Value × 100
Example
Loan Amount: $720,000
Property Value: $800,000
LVR = 90%
Generally:
- 80% LVR = Lower lender risk
- Above 80% LVR = Higher lender risk
- Higher LVR may require LMI
Understanding LVR is important because it can affect loan approval, interest rates, and costs.
What Is Lenders Mortgage Insurance (LMI)?
Lenders Mortgage Insurance is an insurance premium that protects the lender when a borrower has a smaller deposit.
It’s important to understand that:
LMI protects the lender, not the borrower.
LMI may apply when:
- Your deposit is less than 20%
- Your LVR exceeds 80%
The cost varies depending on:
- Property value
- Deposit size
- Loan amount
- Lender policies
In some cases, LMI can add thousands of dollars to borrowing costs.
Government Schemes That May Help
The Australian Government offers programs designed to help eligible first home buyers enter the property market sooner.
First Home Guarantee
Eligible buyers may be able to purchase a property with a smaller deposit without paying LMI.
This can significantly reduce upfront costs.
First Home Super Saver Scheme
Allows eligible individuals to save for a home deposit through voluntary superannuation contributions.
State-Based Assistance
Depending on your location, you may also qualify for:
- Stamp duty concessions
- First home buyer grants
- Regional incentives
Eligibility requirements vary, so it’s important to seek current advice.
What Counts Towards Your Deposit?
A deposit can come from various sources, including:
Savings
The most common source of a home loan deposit.
Gifted Funds
Some lenders may accept financial gifts from immediate family members.
Equity in Another Property
Existing homeowners may use available equity to help finance another purchase.
Government Grants
Eligible grants may contribute toward purchasing costs.
What Is Genuine Savings?
Some lenders require evidence of “genuine savings.”
Genuine savings generally refer to funds accumulated and held over time, demonstrating financial discipline.
Examples may include:
- Regular savings deposits
- Term deposits
- Shares
- Managed funds
Requirements vary between lenders.
Don’t Forget the Additional Costs
Many buyers focus solely on the deposit and overlook other purchasing expenses.
These costs can add up quickly.
Stamp Duty
Depending on the state or territory, stamp duty can be one of the largest upfront costs.
Some first home buyers may qualify for concessions or exemptions.
Conveyancing Fees
A solicitor or conveyancer helps manage the legal aspects of the transaction.
Building and Pest Inspections
Recommended to identify potential property issues before purchase.
Registration Fees
Government fees associated with registering the property and mortgage.
Moving Costs
Removalists, utility connections, and other relocation expenses should also be considered.
Example: Total Upfront Costs
Let’s assume:
Property Price: $800,000
Deposit (10%): $80,000
Additional Costs:
- Stamp Duty: Variable depending on location
- Conveyancing: Approximately $1,500–$3,000
- Building Inspection: Approximately $400–$800
- Registration Fees: Variable
The total funds required may exceed the deposit alone.
This is why planning ahead is important.
Is It Better to Wait for a Larger Deposit?
Many buyers wonder whether they should:
- Buy now with a smaller deposit, or
- Continue saving for a larger deposit.
The answer depends on individual circumstances.
Reasons to Wait
- Avoid LMI
- Reduce monthly repayments
- Borrow less
- Build stronger financial buffers
Reasons to Buy Sooner
- Property values may increase while you’re saving
- Earlier entry into the property market
- Begin building equity sooner
There is no one-size-fits-all answer.
A personalised assessment can help determine the most appropriate strategy.

Common Deposit Mistakes to Avoid
Using Every Dollar for the Deposit
Always retain an emergency buffer for unexpected expenses.
Forgetting About Buying Costs

Frequently Asked Questions

What Happens If My Deposit Is Less Than 20%?

The Bottom Line
While a 20% deposit remains a common benchmark, it’s not the only path to home ownership.

The key is understanding your options, planning for all associated costs, and choosing a loan strategy that aligns with your financial goals.
