Understanding deposit requirements in Australia

Your deposit is a key factor in securing a home loan, influencing both your borrowing costs and loan conditions. While a larger deposit lowers lender risk, you can still purchase property with a smaller one if you understand the trade-offs. What different deposit levels mean:

  • Larger deposits reduce risk: Often avoid additional insurance costs and can unlock better interest rates.

  • Smaller deposits are possible: You may need to pay lender insurance unless eligible for government support.

  • Borrowing power changes: A bigger deposit generally increases how much you can safely borrow.

Navigating these options can be complex for first-home buyers. HeyNest connects you to independent brokers who assess your eligibility for low-deposit pathways or government schemes.

What is the minimum mortgage deposit percentage?

Although lenders prefer a larger deposit, the minimum required for many Australian borrowers can be significantly lower. However, smaller deposits require careful budgeting and understanding the full costs beyond the purchase price. What to consider with lower deposits:

  • Lender’s Mortgage Insurance (LMI): Usually applies when borrowing a high percentage of the property value.

  • Additional upfront costs: Legal fees, inspections, stamp duty and bank charges are separate from your deposit.

  • Loan-to-Value Ratio (LVR): A high LVR can restrict your loan options and increase costs.

If you don’t have a large deposit, expert guidance is essential. HeyNest brokers specialise in low-deposit scenarios and help you secure the most cost-effective structure for your situation.

Strategies to achieve the best deposit percentage

Whether saving a small or large deposit, smart planning helps you reduce borrowing costs and improve your loan options. The goal is not just saving money, but using it strategically to lower risk. Ways to strengthen your deposit position:

  • Family support options: A family member can guarantee part of the loan to avoid insurance costs.

  • Government assistance: Grants and guarantee schemes can reduce or replace a required deposit.

  • Using property equity: Existing homeowners can leverage equity to fund a new purchase.

Choosing the right strategy depends on timing, eligibility and future financial goals. HeyNest brokers compare options without bank bias to help you secure the most beneficial deposit structure.

Frequently asked questions

Is LMI compulsory in Australia?

Yes, it is compulsory for the vast majority of loans where the deposit is less than 20% of the property value (LVR over 80%).

Can I avoid LMI with a small deposit?

Yes, primarily through government schemes like the First Home Guarantee or by using a Family Pledge/Guarantee.

Does the size of my mortgage deposit percentage affect my interest rate?

Generally, yes. Having a 20% or higher deposit (lower LVR) often qualifies you for lower, more competitive interest rates.
