The typical deposit bands in Australia are 20% (no lenders mortgage insurance), 10% (LMI usually applies) and 5% (LMI or a government guarantee). Eligible first home buyers can enter the market with as little as 5% through the Australian Government’s 5% Deposit Scheme, but the deposit is never the whole savings target. Stamp duty, legal fees and inspection costs sit on top of it, and skipping that math is where most buyers get caught short.
TL;DR:
- A 20% deposit in Australia typically avoids lenders mortgage insurance, while a 10% deposit almost always triggers it, increasing costs significantly.
- The Australian Government’s 5% Deposit Scheme allows first home buyers to purchase with just 5% upfront, but the total purchase costs, including stamp duty and fees, often double the initial deposit.
- Lenders often require mortgage insurance with deposits below 20%, which can be capitalized into the loan and increases overall interest payments over time.
- Including stamp duty, legal fees, and inspection costs, the total upfront expense can reach up to $80,000 on a $500,000 property, well above just the deposit amount.
- Using the First Home Super Saver Scheme and automating savings can accelerate deposit building, but many buyers underuse the scheme due to its complexity.

What does a 5%, 10% or 20% property deposit amount to in Australia?
Lenders talk in terms of loan-to-value ratio (LVR), the slice of the purchase price you’re borrowing versus the slice you’re funding yourself. A 20% deposit means an 80% LVR, which is the threshold most banks use to waive lenders mortgage insurance. Drop to a 10% deposit and your LVR climbs to 90%, which almost always triggers LMI. At 5% deposit and a 95% LVR, you’re either paying a heavier LMI premium or relying on a scheme like the First Home Guarantee to get the loan approved at all.
The dollar figures make the trade-off concrete. On a $500,000 home, the gap between a 5% deposit and a 20% deposit is $75,000, money that either sits in your bank account or gets borrowed and charged interest for decades.
Those numbers assume the lender values the property at the purchase price. If a bank’s valuation comes in lower than what you’ve agreed to pay, your effective LVR rises and you may need to top up the deposit to cover the shortfall. Money.com.au’s analysis puts the national average home loan deposit at roughly $173,000, though that average masks big state variation, with New South Wales sitting well above it and Queensland below.
How does the Australian Government 5% Deposit Scheme work?
The Australian Government 5% Deposit Scheme, officially the First Home Guarantee, exists to solve exactly the problem in the table above: the 15 percentage point gap between a 5% deposit and the 20% banks prefer.
Eligibility isn’t automatic. You need to be a first home buyer, intend to live in the property as an owner-occupier, and hold Australian citizenship or permanent residency. Property price caps apply and vary by region, and only participating lenders offer places under the scheme in a given financial year. Housing Australia’s factsheet sets out the exact guarantee mechanics and caps.
Confirm the current price cap for your area and check which lenders still have places before you lock in a savings target. Caps and lender lists shift, and building a budget around outdated figures is a common, avoidable mistake.
What does LMI cost, and can you avoid it?
Lenders mortgage insurance protects the bank, not you, if you default and the sale proceeds don’t cover the loan. Mozo’s lending research confirms most lenders accept a minimum 5% deposit, but almost always with LMI attached unless a guarantee applies.
Most lenders let you capitalise it into the loan rather than pay it upfront, which is convenient but means you’re paying interest on the premium itself for years. Each option carries its own lender conditions worth checking early.
What other upfront costs do you need besides the deposit?
The deposit is rarely the biggest shock in a property purchase, the total cost to buy is. Moneysmart is blunt about this: budget for stamp duty, legal and conveyancing fees, building and pest inspections, and lender application fees on top of the deposit itself.
Stamp duty varies by state and by whether you qualify for a first home buyer concession, so check your state revenue office’s calculator rather than relying on a national rule of thumb. That can push your real savings target closer to $80,000, well above the $60,000 deposit figure alone. Our guide to hidden home buying costs breaks these down further.
How can you save a deposit faster, and what is the FHSSS?
The First Home Super Saver Scheme lets eligible first home buyers make voluntary contributions into super and withdraw up to $15,000 per financial year, capped at $50,000 in total, to help fund a deposit. Because super contributions are taxed at a lower rate than most people’s income tax, the after-tax benefit can be meaningful, though the rules around timing and eligibility are detailed enough that many buyers underuse the scheme simply because they don’t understand it.
Beyond the FHSSS, the mechanics of saving faster haven’t changed much:
- Automate a fixed transfer to a separate savings account on payday, before you can spend it.
- Pay down high-interest debt first; a credit card at 20% interest costs more than most savings accounts earn.
- Ask about salary sacrificing into super if the FHSSS applies to your situation.
- Build a side income stream and direct all of it to the deposit fund.
- Set your real target using the deposit plus stamp duty and fees, not the deposit figure alone.
Pro Tip: Combine FHSSS contributions with a high-interest savings account for the non-super portion of your deposit. Splitting your strategy this way means you’re capturing the tax benefit on part of your savings while keeping the rest liquid for costs the scheme doesn’t cover, like stamp duty.
A buyer saving a consistent amount each month alongside FHSSS contributions could realistically build a substantial deposit in a few years, faster if income grows or a bonus comes in mid-way. Our financing options guide covers more ways to structure this timeline.
Can a buyer’s agent help if your deposit is limited?
A buyer’s agent doesn’t change how much deposit a lender requires, but it changes what that deposit can buy. Invision Property acts exclusively for the buyer, searching off-market and pre-market listings, running due diligence, and negotiating price down rather than up under a fixed-fee model. For a buyer with a constrained deposit, finding underpriced stock or avoiding a bidding war can matter more than the deposit percentage itself, though outcomes depend on market conditions and stock availability at the time.
What actually moves the needle on a deposit strategy
That framing is backwards for a lot of first home buyers.
Where I think the conventional advice genuinely falls short is on upfront costs. Every deposit calculator online focuses on the headline percentage and treats stamp duty and legal fees as an afterthought, when in practice they’re the line item that blows out a budget three weeks before settlement. Prioritise a savings target that includes the full cost to buy, not just the deposit, before you even start looking at listings.
The FHSSS deserves more attention than it gets too. It’s underused not because it’s a bad scheme, but because the mechanics are genuinely confusing on first read. A buyer who takes the time to model the after-tax numbers properly, rather than dismissing it as “too complicated,” often finds it’s worth several thousand dollars over a standard savings account.

Get expert help buying with a smaller deposit
A buyer’s agent can be an alternative to searching listings alone when your deposit is tight and the market is competitive. Some agencies charge a transparent fixed fee rather than a percentage of the purchase price, aligning incentives to negotiate price down. Through agent networks in various regions, buyers can access off-market and pre-market stock often unavailable to the general public, which can be valuable when time is limited or buying interstate.
If a smaller deposit means you need every negotiation edge you can get, book a free strategy session and see what our off-market buyer’s agent service can find for your budget.

FAQ
How much deposit do I need for a $500,000 property?
Eligible first home buyers can use the 5% figure under the First Home Guarantee without paying LMI.
How much deposit do I need for a $700,000 house?
Remember to budget separately for stamp duty and legal fees on top of whichever deposit band you’re targeting.
Can I buy a house with a $20,000 deposit?
It depends on the property’s value and your eligibility for the First Home Guarantee.
Is a 5% deposit enough to avoid lenders mortgage insurance?
Not on its own.
Does a buyer’s agent help if I only have a small deposit saved?
A buyer’s agent can’t change lender deposit requirements, but finding better-value or off-market properties can help your deposit stretch further and reduce the risk of losing out in a competitive bidding process.
