Buying a home with a smaller deposit can be possible, but understanding the lending rules is essential before you start house hunting.
A low deposit home loan can help some New Zealand buyers enter the property market without waiting until they have saved a 20% deposit. However, a smaller deposit usually means a larger loan, and lenders still assess your income, expenses, debts, credit history and overall financial position.
For buyers planning to purchase in 2026, it is important to understand how low-deposit lending works, what LVR and DTI rules mean, how KiwiSaver could help with your deposit and what costs you need to budget for.
If you are starting your home-buying journey, you can also explore GM Finance home loan options to understand the types of lending available for different property purchases.
What Is a Low Deposit Home Loan?
A low deposit home loan allows you to borrow with a deposit below the commonly used 20% benchmark.
For example, if you are buying a $600,000 property, a 20% deposit would be $120,000. A 10% deposit would be $60,000, while a 5% deposit would be $30,000.
A low deposit home loan can therefore reduce the amount you need to save before you can consider buying.
However, the deposit is only one part of a mortgage application. The lender will still assess whether you can afford the repayments and whether the application meets its lending policies.
A smaller deposit does not automatically mean that a lender will approve your home loan.
Your income, expenses, existing debts, credit commitments, employment and the property itself can all influence the lending decision.
Can You Get a Low Deposit Home Loan With a 5% Deposit?
Some eligible buyers may be able to purchase with a 5% deposit through specific lending options.
The Kāinga Ora First Home Loan is designed for eligible first-home buyers and can allow a deposit of 5%, subject to the scheme’s eligibility requirements and participating lender criteria.
This does not mean every first-home buyer can automatically obtain a 5% low deposit home loan.
Your application still needs to meet the relevant requirements, and the participating lender will assess your financial position.
For buyers considering this option, it is important to check the current Kāinga Ora requirements before relying on a 5% deposit as part of your buying plan.
1. Understand How LVR Works With a Low Deposit Home Loan
Loan-to-value ratio, or LVR, is one of the most important terms to understand when you have a small deposit.
LVR compares the amount you borrow with the value of the property.
For example:
- Property value: $600,000
- Deposit: $60,000
- Mortgage: $540,000
- LVR: 90%
In this example, the buyer has a 90% LVR.
A low deposit home loan normally results in a higher LVR because you are borrowing a larger percentage of the property’s value.
As of August 2026, the Reserve Bank of New Zealand’s current settings allow banks to have up to 25% of new owner-occupier lending above 80% LVR. This is a limit on the proportion of a bank’s new lending, not a guarantee that an individual borrower will receive a high-LVR loan. Banks continue to apply their own lending criteria.
You can read the latest information on LVR restrictions from the Reserve Bank of New Zealand.
2. A Smaller Deposit Means a Larger Mortgage
The amount you save as a deposit directly affects how much you need to borrow.
Consider a $700,000 property:
| Deposit | Deposit amount | Approximate loan |
|---|---|---|
| 20% | $140,000 | $560,000 |
| 15% | $105,000 | $595,000 |
| 10% | $70,000 | $630,000 |
| 5% | $35,000 | $665,000 |
The smaller the deposit, the more you generally need to borrow.
A larger mortgage can mean higher repayments and more interest over the life of the loan.
That is why buyers should not focus only on how quickly they can reach the deposit requirement. You also need to consider whether the resulting mortgage repayments fit comfortably within your household budget.
3. Your Income and Expenses Still Matter
Having a low deposit does not remove the lender’s affordability assessment.
When assessing a low deposit home loan, lenders may look at your income, employment, household expenses, existing loans, credit cards, Buy Now Pay Later commitments and other regular financial obligations.
For example, someone with a 10% deposit may still have difficulty obtaining approval if their existing debts and expenses leave limited income available for mortgage repayments.
Preparing your finances before applying can therefore be just as important as building your deposit.
GM Finance has published a useful guide on how to improve your chances of home loan approval, including practical steps around income, expenses, debts, savings and documentation.
4. Debt-to-Income Rules Can Affect Your Borrowing
Your deposit is only one part of the borrowing calculation because your income and existing debt also matter.
Debt-to-income, or DTI, restrictions apply alongside LVR restrictions to new residential lending by banks.
The Reserve Bank explains that owner-occupier borrowing above a DTI ratio of 6 is considered high-DTI lending, while the threshold for investors is 7. Banks can still undertake a limited amount of lending above these thresholds, and they must also apply their own affordability assessments.
You can check the latest DTI information from the Reserve Bank of New Zealand before planning your borrowing.
For a low deposit home loan applicant, this matters because a smaller deposit generally means a larger mortgage.
A larger mortgage can increase your overall debt-to-income ratio, particularly when your income is relatively low compared with the amount you want to borrow.
5. KiwiSaver Could Help Build Your Deposit
Eligible first-home buyers may be able to use KiwiSaver savings towards their home purchase.
Inland Revenue states that eligible KiwiSaver members may be able to withdraw most of their savings for a first home after at least three years of membership, subject to the applicable rules. You must leave $1,000 in the account.
You can check the current requirements through Inland Revenue’s KiwiSaver first-home withdrawal information.
For some buyers, combining eligible KiwiSaver savings with personal savings can help build the deposit needed for a low deposit home loan.
However, make sure you confirm your eligibility with your KiwiSaver provider before including the funds in your purchase budget.
6. Do Not Use Every Dollar for the Deposit
Buying a home involves costs beyond the deposit.
If you are planning a low deposit home loan, leave room in your budget for expenses such as:
- Solicitor or conveyancing costs
- Building inspection
- Property valuation where required
- House insurance
- Moving costs
- Council rates
- Immediate maintenance
- Loan-related fees where applicable
Using every dollar of your savings for the deposit can leave you with very little financial buffer after settlement.
A realistic home-buying budget should therefore include both the deposit and the other costs associated with purchasing a property.
7. Mortgage Pre-Approval Can Help Before House Hunting
Getting mortgage pre-approval can give you a clearer idea of your potential borrowing position before you start making offers.
With a low deposit home loan, knowing your approximate borrowing capacity can be particularly useful because your deposit, income, debts and property price all need to work together.
GM Finance explains that pre-approval can help buyers establish a realistic property budget, understand potential borrowing limits and prepare the documents needed for a mortgage application.
Read GM Finance’s guide to mortgage pre-approval before buying a home before you start seriously searching for a property.
Remember that pre-approval is not the same as final loan approval.
The lender may still need to assess the specific property and confirm that all conditions have been met.
8. Compare the Full Cost of a Low Deposit Home Loan
The interest rate is important, but it should not be the only thing you compare.
When considering a low deposit home loan, look at the complete loan structure.
Consider:
- Interest rate
- Fixed or floating options
- Loan term
- Establishment or application fees
- Any applicable mortgage insurance or low-equity costs
- Cash contributions
- Repayment flexibility
- Extra repayment options
- Offset facilities where available
- Revolving credit options
- Break costs
A low deposit can help you enter the market sooner, but you need to understand the overall cost of borrowing.
Ask your mortgage adviser to explain the loan structure and any additional costs before you commit.
9. Prepare Your Finances Before Applying
A well-prepared application can make the mortgage process more organised.
Before applying for a low deposit home loan, review your financial position carefully.
Check Your Regular Spending
Your bank statements can show where your money goes each month.
Review subscriptions, entertainment, shopping, travel and other discretionary spending.
You do not necessarily need to stop every non-essential purchase, but understanding your spending can help you create a realistic mortgage budget.
Review Existing Debt
Existing debt can affect how much you may be able to borrow.
Review:
- Credit cards
- Personal loans
- Car finance
- Student loans
- Buy Now Pay Later accounts
- Other repayment commitments
Reducing unnecessary debt may improve your monthly cash flow and make your financial position easier to manage.
Maintain Your Savings Pattern
Regular saving can help demonstrate that you can manage a financial commitment.
Keep records of your savings and make sure you can clearly explain the source of your deposit if your lender asks.
Avoid Unnecessary New Debt
Taking on significant new borrowing shortly before applying can change your financial position.
Think carefully before taking out a new car loan, personal loan or additional credit facility while preparing your mortgage application.
For more preparation tips, read GM Finance’s guide on improving your chances of home loan approval.
Low Deposit Home Loan vs 20% Deposit
A smaller deposit can reduce the time needed to save, but it also increases the amount you borrow.
Here is a simple example using a $600,000 property:
| Deposit | Cash deposit | Approximate mortgage |
|---|---|---|
| 20% | $120,000 | $480,000 |
| 15% | $90,000 | $510,000 |
| 10% | $60,000 | $540,000 |
| 5% | $30,000 | $570,000 |
These figures show why buyers should consider both the upfront deposit and the long-term cost of the mortgage.
A 20% deposit is not necessarily required in every situation, but the available lending options depend on your circumstances and the lender’s criteria.
Who May Consider a Low Deposit Home Loan?
A low deposit home loan may be relevant for buyers who have a stable financial position but have not yet saved a large deposit.
It may be worth discussing low-deposit options if you are:
- A first-home buyer
- Building your deposit through KiwiSaver and savings
- Receiving acceptable family assistance
- Earning a stable income
- Able to manage potential mortgage repayments
- Looking at properties within a realistic price range
- Ready to obtain mortgage pre-approval
These factors do not guarantee approval.
The lender will assess your individual circumstances and apply its own lending criteria.
Common Low Deposit Home Loan Mistakes to Avoid
Understanding common mistakes can help you prepare before submitting your application.
Assuming a 5% Deposit Guarantees Approval
A 5% deposit does not automatically qualify every buyer for a mortgage.
Specific schemes have eligibility requirements, and lenders still assess affordability and lending risk.
Spending All Your Savings
Do not forget about the costs that come with buying and moving into a home.
Keep some money available for legal, inspection, insurance and other property expenses.
Taking on New Debt
New borrowing can change your overall financial position.
Think carefully before taking on major new financial commitments during the mortgage application process.
House Hunting Before Knowing Your Budget
Looking at properties before understanding your borrowing position can lead to unrealistic expectations.
Mortgage pre-approval can help you establish a more realistic price range.
GM Finance also covers common first-home buyer mortgage mistakes that borrowers should consider before applying.
