The house deposit you need depends on your financial situation and loan type, but understanding the minimum requirements can save you tens of thousands of dollars. In Australia, the minimum house deposit is typically 5% of the property purchase price, but aiming for 20% can help you avoid expensive Lenders Mortgage Insurance (LMI) and secure better interest rates. This comprehensive guide breaks down exactly how much you need, what LMI costs, and proven strategies to reach your deposit goal faster.
Minimum House Deposit Requirements in Australia
Most Australian lenders require a minimum house deposit of 5% to 20% of the property’s purchase price. The exact amount depends on several factors including your income, credit history, employment status, and whether you qualify for any government assistance schemes.
For first home buyers, the Australian Government First Home Guarantee Scheme allows eligible buyers to purchase with as little as 5% deposit without paying LMI. However, most conventional loans require 20% to avoid LMI altogether.
Standard Deposit Percentages Explained
Here’s what different house deposit levels mean for your purchase:
- 5% deposit: Minimum for most loans, but requires LMI and limits your borrowing power
- 10% deposit: More lender options available, but still subject to significant LMI costs
- 15% deposit: Reduced LMI premiums and better negotiating position with lenders
- 20% deposit: No LMI required, access to best interest rates, and full loan features

The True Cost of Lenders Mortgage Insurance
LMI is a one-time premium that protects the lender (not you) if you default on your loan. Many buyers underestimate the real cost because LMI is typically added to your loan amount rather than paid upfront.
For an $800,000 house with a 5% deposit ($40,000), your LMI could be approximately $75,000. When this fee is financed into your loan at 4.5% interest over 30 years, you’ll pay an additional $34,000 in interest charges. The true total cost of that LMI becomes $109,000, nearly three times your original deposit amount.
LMI Cost Factors
Several factors influence your LMI premium:
- Loan-to-value ratio (LVR): higher LVR means higher premiums
- Property location and type
- Your employment type (self-employed typically pay more)
- Loan amount and property value
- Whether you’re an owner-occupier or investor
Five Proven Strategies to Build Your House Deposit Faster
1. High-Interest Savings Account Strategy
Open a dedicated high-interest savings account and set up automatic transfers on payday. Many banks offer bonus interest rates (up to 5.5% as of 2024) if you deposit regularly and don’t make withdrawals. For a $160,000 deposit goal, saving $2,000 monthly at 5% interest gets you there in approximately 6 years.
2. First Home Super Saver Scheme (FHSSS)
The FHSSS allows first home buyers to save up to $50,000 inside their superannuation fund, taking advantage of the concessional 15% tax rate on contributions. You can contribute up to $15,000 per year and later withdraw these contributions plus earnings to use as a house deposit.
3. Family Guarantee or Gifted Deposit
Parents or close family members can gift funds toward your deposit or act as guarantors, using their property equity to reduce your LVR. A family guarantee can help you borrow up to 100% of the property value without LMI, though this does put the guarantor’s property at risk.
4. Government Grants and Schemes
Several government programs assist first home buyers with smaller deposits. The First Home Guarantee allows eligible buyers to purchase with just 5% deposit without LMI. Each state also offers first home buyer grants (typically $10,000-15,000) and stamp duty concessions that can significantly reduce upfront costs.
5. Equity from Existing Property
If you already own property, you can use the equity as a deposit for your next purchase. With sufficient equity (typically 20% or more), you can buy without saving additional cash, though you’ll need to service both loans and manage higher overall debt levels.
Additional Costs Beyond Your House Deposit
Don’t forget these essential costs when budgeting for your home purchase:
- Stamp duty: 3-5.5% of property value (varies by state)
- Legal and conveyancing fees: $1,200-2,500
- Building and pest inspections: $400-800
- Loan application and valuation fees: $300-1,000
- Moving costs: $500-2,000
Budget an additional 5-7% of the purchase price for these transaction costs on top of your deposit.
Should You Wait to Save 20% or Buy Sooner?
This depends on market conditions and your personal circumstances. If property prices are rising 8-10% annually, waiting two years to save an extra $80,000 deposit might cost you $96,000-120,000 in price growth on a $600,000 property. Understanding first home buyer market trends can help you make this timing decision.
Conversely, if prices are stable or falling, taking time to build a larger deposit saves you from LMI costs and provides better loan terms. Consider consulting a mortgage broker vs bank comparison to understand your specific borrowing capacity and whether waiting makes financial sense.
Your loan structure also matters. Learn about fixed vs variable loan rates to understand how different mortgage types affect your repayment strategy.
