Finding the Best Mortgage Solutions Tailored for You

If you’re planning to buy a home in Hamilton or anywhere in the Waikato region, one of the first questions you’ll ask is: How much can I borrow for a mortgage? It’s a big decision, and the answer depends on a few key things — your income, your expenses, your deposit, and even your credit score.

What Affects How Much You Can Borrow for a Mortgage?

Income, Expenses, and Credit Score

Your income is the starting point. Lenders want to know how much you earn — and how stable that income is. If you’re employed full-time, that’s fairly straightforward. If you’re self-employed or your income varies, they’ll look more closely at your financial history to understand your earning patterns.

But income is only part of the picture. Your existing debts also play a big role. Credit cards, car loans, and other personal loans can all affect how much you’re able to borrow. Lenders consider your total financial commitments to make sure you can comfortably manage a mortgage on top of them. Keeping your debt under control shows you can handle repayments responsibly, which strengthens your application.

Deposit Size and LVR (Loan-to-Value Ratio)

Your deposit is the amount of money you put toward the purchase upfront. In New Zealand, most lenders prefer a deposit of at least 20%. But there are options for lower deposits — especially for first-home buyers. You may be able to get a loan with a deposit from as little as 5%.

How Do Banks and Brokers Assess How Much You Can Borrow for a Mortgage?

Bank Assessments

When you apply directly with a bank, they’ll use their own calculator to work out how much you could borrow. They look at:

• Income – not just how much you earn, but how stable it is (salary, self-employed income, or contract work).
• Expenses – your everyday living costs such as food, transport, insurance, and utilities.
• Debts – things like credit cards, car loans, personal loans, Afterpay, or store finance. Even small limits on unused credit cards are counted.
• Deposit – how much you’ve saved or built up through KiwiSaver or other sources.

On top of that, banks apply a test (or “stress”) interest rate, which is higher than the current rate. This is to check whether you could still afford repayments if interest rates rise in the future.

Broker Assessments

Mortgage brokers, like Andre Stokes here in Hamilton, take a wider view. Instead of relying on just one bank’s criteria, brokers work with multiple lenders — each with their own calculators and lending rules. This means:

• You’ll often have a better chance of approval if one bank says “no.”
• You can compare borrowing amounts across lenders.
• You’re more likely to find a solution that fits your income, debt, and goals.

Brokers also help you present your application in the best light — especially if you’re self-employed, have variable income, or already have existing debts.

Borrow for a Mortgage in Waikato: What’s Typical?

Waikato Property Prices

Property values across the Waikato Region can vary considerably, depending on the location:

• Hamilton City: The average house price as of June 2025 is approximately NZ$788,171, according to CoreLogic data compiled by Opes Partners.
• Waikato Region Overall: Median prices hover around NZ$735,000 as of June 2025, having surged from about NZ$340,000 a decade earlier.
• Te Kūiti (Waitomo District): This remains one of the most affordable areas in the region. The average house value stands at NZ$392,550,

This underscores a substantial price range—from Te Kūiti’s mid-$300k to Hamilton’s upper-$700k—highlighting how location plays a pivotal role in affordability for buyers.

First-Home Buyers in Waikato

If you’re taking your first steps onto the property ladder, you may have access to several helpful schemes:

1. KiwiSaver First-Home Withdrawal

After contributing to KiwiSaver (or a complying super fund) for at least three years, you may be able to withdraw most of your savings—including member contributions, employer contributions, government contributions, and investment earnings—to help with your first home purchase.

You must leave a minimum of NZ$1,000 in your KiwiSaver account, and not all funds are withdrawable (e.g., Australian super transfers and certain government kick-start amounts may be excluded).

Withdrawals are restricted to a property you intend to live in—this cannot be used to purchase investment properties.

2. Kāinga Ora First-Home Loan

With this option, you can secure a home loan with a deposit as low as 5%, thanks to Kāinga Ora underwriting the remainder of the deposit risk for participating lenders.
Kāinga Ora – Homes and Communities

Eligibility criteria include being a first-home buyer (or a previous owner in a similar financial place as a first-home buyer), meeting maximum income thresholds (e.g., <$95,000 for individuals without dependants or <$150,000 combined for co-buyers), and purchasing a home you intend to live in.

The loan includes a 1.2% Lender’s Mortgage Insurance (LMI) premium, payable upfront or added to the loan balance.

Tips to Increase How Much You Can Borrow for a Mortgage

1. Reduce Your Debt
   Banks look closely at your existing debt, such as credit cards, personal loans, and car finance. Paying these down (or closing unused credit facilities) lowers your monthly commitments, which can free up more borrowing power.

2. Increase Your Deposit
   The bigger your deposit, the less risk the lender takes on. This can not only increase how much you’re able to borrow but may also give you access to better interest rates and more lenders.

3. Improve Your Credit Score
   Your credit history shows lenders how reliable you are with money. Paying bills on time, avoiding missed payments, and keeping debt levels manageable can strengthen your application and make banks more willing to lend.

4. Use a Broker
   Mortgage brokers have access to a wide range of lenders and know the different borrowing criteria. They can help present your situation in the best possible way and find a lender who’s more likely to offer you the maximum amount.
