How much of a deposit do I need to buy a house in NZ?

What Deposit Do I need?

In New Zealand, the amount of deposit you'll need to buy a house can depend on various factors, including the type of mortgage you're applying for, your financial situation, and the policies of the lender. Here is a break down to help you understand.

New Zealand Home Deposits

Typical Deposit Amount

The most common requirement among lenders is a minimum deposit of 20% of the purchase price of the property. This means if you're buying a house valued at $500,000, you'd need a deposit of $100,000. However, some lenders may accept a smaller deposit, such as 10%, but this could come with conditions like higher interest rates or the need for mortgage insurance.

 

Why a Larger Deposit Helps

Having a larger deposit has its advantages:

  • Better Mortgage Terms: Lenders might offer lower interest rates and fees.
  • Less to Borrow: A larger deposit means borrowing less, which leads to lower monthly repayments and less interest over time.
  • More Attractive to Lenders: A bigger deposit shows you're good at saving and managing money.

 

Help for First-Time Home Buyers

It's important to note that the New Zealand government offers schemes like the First Home Loan and KiwiSaver, which can help eligible first-home buyers with their deposit. These schemes provide financial assistance to qualified applicants, allowing them to buy a home with a lower deposit than they might otherwise need.

 

Talk to a Mortgage Advisor

Before you start house hunting, it's a good idea to speak with a mortgage advisor. They can assess your financial situation, discuss your options, and help you determine the deposit amount required for your specific circumstances.

  • I highly recommend Greg Miller of Advanced Mortgage Solutions, Chch. I went in for an appointment with Greg to see if it was possible or what I needed to achieve financially in order to purchase my first home, not thinking that a few months later, I would now own my first home. He is very professional and knowledgeable in this field, with clear and understandable communication and very patient with my questions, etc, as well as keeps you up to date all the way through the process. I would recommend Greg to anyone for help in a first home or other mortgage needs or advice. Thank you heaps or everything
