Traction resources / Buying a home

Deposit options explained

You don't always need a 20% deposit to buy a home. Here's how the main options compare, and why choosing the right lender can make a difference.

This guide is for owner-occupiers. That means you're buying a home to live in yourself. Deposit requirements and lending rules are different for investment properties.

Three ways to buy

01 / STANDARD LENDING

20% deposit or more

Usually the widest choice of lenders and access to standard or more competitive advertised rates, subject to eligibility.

02 / FIRST HOME LOAN

From 5% deposit

A Kāinga Ora-backed option for eligible buyers through participating lenders, with a 1.2% insurance premium.

03 / LOW-DEPOSIT LENDING

Less than 20%

Standard bank lending with a smaller deposit, potentially higher rates and more restrictive approval policies.

Let's look at each option

01

Buying with a 20% deposit

With a deposit of 20% or more, you generally have access to a broader range of banks and standard home-loan pricing. This can make comparing interest rates and loan structures more straightforward.

Why it's useful

You'll usually avoid low-equity interest premiums and have more lender options, although approval and pricing still depend on your circumstances.

How we help

We compare the banks' rates, features and lending criteria, then look at how to structure your mortgage around your plans.

02

Kāinga Ora First Home Loan

The First Home Loan scheme can allow eligible buyers to purchase with as little as a 5% deposit through a participating lender. It is designed for first-home buyers and some previous homeowners who meet the scheme's criteria.

Interest rates

Participating lenders generally offer their standard home-loan rates rather than applying a conventional low-equity margin. The actual rate and any fees depend on the lender and loan product.

Lender's Mortgage Insurance (LMI)

There is a one-off LMI premium of 1.2% of the loan amount. This can be paid upfront or added to the mortgage, subject to the lender's process. Adding it to the loan means you may also pay interest on that amount.

Eligibility matters

There are income limits, residency requirements, property and ownership rules, and lender affordability checks. Not every lender offers the scheme, and eligibility doesn't guarantee approval.

How we help

We check whether this pathway could suit you, review the participating lenders' criteria and compare the total cost against other low-deposit options.

03

Standard low-deposit lending

If you have less than a 20% deposit, you may still be able to buy through a standard home loan. However, lenders have different rules about which applications they'll consider and how they'll price them.

Why pre-approval can be harder

Banks operate within Reserve Bank limits on how much new lending they can provide to borrowers with deposits below 20%. Because this lending capacity is limited, some lenders can be more selective about issuing low-deposit pre-approvals. Policies can depend on whether you're an existing customer and whether you've already found a property.

What if you've already had an offer accepted?

Some banks may be more willing to assess a complete application for a specific property than provide an open-ended pre-approval. This varies by bank and doesn't mean approval is guaranteed. Always talk to your adviser and lawyer before making an offer without suitable finance protection.

Interest rates aren't the same everywhere

Some banks apply a low-equity margin on top of a base rate, often with different tiers depending on your loan-to-value ratio (LVR). Others use separate low-equity pricing or different rate structures. This means two banks can produce very different costs for the same deposit.

What happens when your equity improves?

At some lenders, you may be able to move to a better low-equity pricing tier during a fixed term after meeting their requirements. At others, changes may need to wait until refix or be subject to different conditions. Property valuation requirements can also vary.

How we help

We compare which banks are currently considering low-deposit applications, their pre-approval approach, the actual rates and premiums, and how easy it may be to improve your pricing as you build equity.

How the options compare

Why your mortgage adviser matters

A deposit percentage is only one part of the picture. Two banks can look at the same application differently, and the cheapest-looking rate isn't always the lowest-cost option over time.

01 / Understand your deposit

We look at what you have available and where the funds are coming from.

02 / Check your options

We review eligibility, lender criteria and whether pre-approval is realistic.

03 / Compare the costs

We look at interest rates, low-equity premiums, insurance fees and future pricing changes.

04 / Plan the next step

We help you understand the process and choose a suitable lending pathway.
