How much deposit do you need to buy your first home?

3 MIN READ 28/08/2025

Today, we’re focusing on the two key factors that determine your mortgage options:

Your deposit size
Your ability to service debt

Understanding these factors is essential to building a solid foundation for your home-buying journey. Let’s break them down.

How much deposit is enough
Setting a realistic deposit goal is a great starting point. Your deposit size impacts your mortgage eligibility, potential interest rates, and overall loan costs.

Here are some key deposit benchmarks:

5% deposit: Minimum required for the Kāinga Ora First Home Loan. It allows you to enter the market sooner but comes with additional costs like Lender’s Mortgage Insurance (LMI) and eligibility criteria.
10% deposit: Minimum deposit without government support, low equity premiums (LEP) and low equity margins (LEM) apply.
15% deposit: Mid range low equity price point.
20% deposit: The ideal target. Reaching this level can unlock the most competitive interest rates and eliminate the need for low equity premium or low equity margin, saving you money over time.

To understand your deposit in context, consider your Loan-to-Value Ratio (LVR). LVR is the percentage of your property’s value that you’re borrowing. For example, if you’re purchasing a home worth $700,000 and have a $140,000 deposit, your LVR would be 80%. Lower LVRs are preferred by lenders because they pose less risk.

Determine your borrowing power
Your ability to service debt is the second factor to consider, and it’s influenced by two key considerations:

Debt-to-Income Ratio (DTI): This measures how much debt you have relative to your income. A lower DTI improves your borrowing prospects by demonstrating financial stability.
Monthly cash surplus: This is your uncommitted income after tax minus your living expenses and borrowing repayments (calculated at lender test rates) = your uncommitted income.

Tips to strengthen your borrowing power:

Reduce personal debt: Lowering debt levels can boost your financial profile.
Improve your credit score: A strong credit score can qualify you for better loan terms and interest rates. You can boost your credit score by paying your utility bills in a timely manner, avoid overdrawing your accounts or exceeding your credit limit, and ensure any personal finance is paid on time.
Boost your savings and KiwiSaver contributions: Growing your savings and KiwiSaver contributions not only supports your deposit but also demonstrates solid financial habits to lenders.
Consider repaying your student loan: Paying off your student loan can positively impact your DTI as you’ll no longer have these deductions from your salary.
Increase your income: Additional income streams can enhance your borrowing potential.
