Is a 20% Deposit Necessary to Buy a Property?

If you are an aspiring homeowner, then you will need to know if you really need a 20% deposit to buy a property.

The short answer is no, but it certainly helps. 

A 20% deposit is the traditional ‘gold standard’ but it’s important to understand why and what your options are if you’re not quite there yet.

Why The 20% Deposit Is Important

In the eyes of the Lender, having a 20% deposit positions you as a lower-risk borrower. It also helps as it unlocks tangible benefits:

  • Access to Better Interest Rates
  • No Low Equity Fees
  • Lower Monthly Repayments
  • More Financial Flexibility.

Currently, Banks are also restricted by the Reserve Bank on how much they can lend to borrowers with less than 20% deposit, making these loans harder to obtain.

What if Your Deposit Is Less Than 20%

If your deposit is under 20%, you’re considered a ‘low equity’ or ‘low deposit’ borrower. This then means there are a different set of rules and challenges:

  • LVR Restrictions: Banks have a strict quota and can only allocate a certain percentage of their new lending to low-deposit borrowers. This creates fierce competition for limited funding.
  • Higher Costs: You may face slightly higher interest rates and will almost certainly have to pay a Low Equity Fee (LEF). This is a one-off fee or an ongoing margin added to your interest rate, designed to cover the Bank’s increased risk.

Key Options for Low-Deposit Buyers

First-time buyers can access dedicated schemes to help borrowers get on the ladder sooner:

  • The First Home Loan (Kainga Ora): This offers eligible buyers to purchase a home with as little as a 5% deposit. It comes with specific income caps, but it’s a powerful option if you fit their criteria.
  • KiwiSaver Withdrawal: If you’ve been contributing to KiwiSaver for at least three years, you may also be eligible to withdraw most of your KiwiSaver to use towards a first home purchase. 

Navigating the criteria for these schemes can be complex, so getting advice early is essential.

How To Boost Your Deposit

Saving for a deposit can feel like a huge challenge, but a clear strategy always helps. Here are some tips…:

  1. Create A Simple Budget: This helps to see where your money is going. Then for any potential surplus, set up an automatic transfer to a high-interest savings account on every payday. Making savings non-negotiable is the fastest way to build your deposit.
  2. Eliminate High-Interest Debt: Lenders look at all your existing debts. Focus on paying off high-interest loans, like credit cards and personal loans, as this improves your borrowing power and frees up more cashflow for saving.
  3. Checkout Family Financial Support: A gift or loan from family can be a massive help. It’s important to document this correctly with a formal gifting declaration or a loan agreement, as this ensures it meets the Bank’s requirements and protects everyone involved.
  4. Explore Co-Ownership: Teaming up with family or friends to pool your deposits together is a modern and increasingly popular strategy. With a solid legal agreement in place, co-owning can get you onto the property ladder years sooner than if you try to do it alone.

Strategy is Key!

While aiming for a 20% deposit is a smart financial goal, it’s not the only way to achieve homeownership. The right path for you depends entirely on your situation.

An experienced Mortgage Adviser can help you create a personalised roadmap – whether that’s a plan to reach a 20% deposit faster, or a strategy to navigate the low-deposit lending landscape with confidence.
