How Much Deposit Do I Need to Buy a House in Australia?

The minimum deposit to buy a house in Australia is generally 5% of the purchase price, though the standard recommendation is 20% to avoid paying lenders mortgage insurance (LMI). For first home buyers using the First Home Guarantee, a 5% deposit is accepted with no LMI required.

The deposit you need depends on the purchase price, the scheme you’re using and your lender’s policy.

What Is LMI and Why Does It Matter?

Lenders Mortgage Insurance (LMI) is charged when you borrow more than 80% of the property’s value (LVR above 80%). Despite its name, LMI protects the lender — not you — if you default on the loan.

LMI premiums are significant and are typically capitalised into the loan (you pay interest on them for years):

Purchase PriceLVR 90% (10% deposit)LVR 95% (5% deposit)
$500,000~$9,000–$14,000~$16,000–$22,000
$700,000~$13,000–$20,000~$23,000–$32,000
$900,000~$17,000–$26,000~$30,000–$42,000

LMI premiums vary by lender and insurer. Use the LMI calculator for an estimate.

The First Home Guarantee allows eligible buyers to borrow up to 95% LVR without paying LMI — the government guarantees the lender for the portion above 80%.


The Real Savings Needed — Beyond Just the Deposit

Many first home buyers underestimate the total savings required. Beyond the deposit itself:

Cost ItemTypical Range
Stamp duty (varies by state, may be exempt for FHB)$0–$45,000+
Conveyancing / legal fees$1,500–$3,500
Building and pest inspection$400–$900
Loan establishment fees$0–$600
Moving costs$800–$2,500
Buffer (emergency fund)1–2 months’ repayments

For a $600,000 purchase in NSW, a first home buyer exempt from stamp duty still needs approximately $30,000 deposit (5% via FHBG) plus roughly $3,000–$5,000 in other upfront costs — a minimum of $33,000–$35,000 in savings, assuming $0 stamp duty.

A non-first-home-buyer purchasing the same property in NSW needs the $30,000 deposit plus approximately $22,490 in stamp duty plus other costs — totalling around $55,000–$60,000.


How Long Does It Take to Save a 20% Deposit?

CityMedian House Price20% DepositYears to Save (at $1,000/month)
Sydney~$1,450,000~$290,000~24 years
Melbourne~$940,000~$188,000~16 years
Brisbane~$900,000~$180,000~15 years
Perth~$780,000~$156,000~13 years
Adelaide~$770,000~$154,000~13 years

This is why many first home buyers use a 5% deposit scheme or pursue more aggressive saving strategies like the FHSS.

Saving $2,000/month halves these timeframes. Using the FHSS scheme (contributing voluntarily to super and withdrawing up to $50,000 for a deposit) adds a tax efficiency advantage that can meaningfully accelerate savings.


Deposit Strategies for First Home Buyers

1. First Home Super Saver (FHSS) Scheme Voluntary super contributions (up to $15,000/year, $50,000 total) are taxed at 15% inside super. When withdrawn for a home purchase, the tax saving compared to after-tax saving can be $3,000–$6,000 per year for mid-to-high income earners.

2. Use the First Home Guarantee Buying with a 5% deposit through the First Home Guarantee avoids LMI — saving $10,000–$35,000 in LMI premiums that would otherwise be payable.

3. Family gift or guarantee Parents can gift money toward a deposit or go guarantor using equity in their own property, allowing you to purchase sooner with a smaller deposit. See gifted deposit guide and guarantor guide.

4. Consider a smaller property or different location A lower purchase price reduces the deposit needed dramatically. Regional areas offer lower entry prices — and the Regional First Home Buyer Guarantee applies the same 5% deposit/no LMI benefit in eligible areas.


Frequently Asked Questions

What is the minimum deposit to buy a house in Australia? The minimum deposit is generally 5%, though some schemes allow as little as 2% for single parents (Family Home Guarantee). Without a scheme, a 5% deposit means paying LMI. With the First Home Guarantee, eligible buyers can borrow 95% with no LMI.

How much do I need to save beyond the deposit? Allow for stamp duty (varies by state — may be zero for first home buyers), conveyancing fees ($1,500–$3,500), building and pest inspection ($400–$900) and a financial buffer. Total additional savings of $3,000–$10,000 beyond the deposit is common for first home buyers with stamp duty exemptions; much more without exemptions.

Do I need genuine savings for a home deposit? Most lenders require at least 5% in “genuine savings” — funds that have been held in your account for at least 3 months. Gifted funds generally cannot count as genuine savings on their own. A guarantor arrangement is an alternative way to meet deposit requirements without genuine savings.

Is a 10% deposit enough to buy a house? Yes, but LMI will apply unless you’re using the First Home Guarantee (which caps the scheme at 95% LVR). At 10% deposit and 90% LVR, LMI costs typically range from $9,000 to $26,000 depending on the loan size.
