Knowing how much loan can I borrow is one of the first questions to answer before you start looking for a home. Your borrowing capacity depends on your income, expenses, existing debts, deposit, credit history, property value and the lender’s assessment of your ability to manage the repayments.
In 2026, New Zealand home buyers also need to understand lending rules such as debt-to-income (DTI) and loan-to-value ratio (LVR) restrictions. These rules work alongside each lender’s own affordability and lending criteria. The Reserve Bank of New Zealand’s DTI guidance explains how these restrictions apply to residential lending.
If you are asking how much loan can I borrow in New Zealand, there is no single figure that applies to everyone. Two people earning the same income can have very different borrowing capacities because their expenses, debts, deposits and financial commitments may be different.
How Much Loan Can I Borrow in New Zealand?
The simplest way to think about borrowing capacity is the amount a lender believes you can afford to repay. A lender looks at your income, expenses and existing financial commitments before deciding how much it may be prepared to lend.
Your borrowing capacity may depend on:
- Your gross household income
- Employment and income stability
- Existing mortgages
- Personal loans
- Credit card limits
- Buy Now Pay Later commitments
- Student loans
- Regular household expenses
- Your deposit
- Your credit history
- The property you want to buy
- Your loan-to-value ratio
- Your debt-to-income position
- The lender’s own affordability assessment
This means the answer to how much loan can I borrow is personal to your financial situation.
Sorted also explains that lenders look at both what you can afford to repay and how much they are prepared to lend against the property. You can read the Sorted guide to how much you can borrow for more information.
1. Your Income Is One of the Biggest Factors
Your income gives the lender a starting point when assessing how much loan can I borrow. The lender needs to understand how much money comes into your household and whether that income is reliable.
Income may include:
- Salary or wages
- Regular overtime where accepted
- Business income
- Self-employed income
- Rental income where accepted
- Other consistent income sources
If you are applying with a partner, the lender may consider both applicants’ income. However, the lender will also assess the financial commitments associated with both applicants.
What If I Am Self-Employed?
Self-employed borrowers may need to provide additional financial information. This can include business financial statements, tax information, accounts and evidence of consistent income.
Your taxable income and the income a lender accepts for servicing purposes may not always be exactly the same. This is why self-employed borrowers should prepare their financial documents before applying.
2. Your Existing Debts Can Reduce How Much You Can Borrow
Existing debt can have a significant effect on how much loan can I borrow. A lender does not only look at your income; it also considers the debts and commitments you already have.
These may include:
- Credit cards
- Personal loans
- Car finance
- Student loans
- Existing home loans
- Buy Now Pay Later accounts
- Overdrafts
- Other financial commitments
For example, two households could each earn $150,000 a year, but the household with fewer debts may have a different borrowing position from the household with several existing loans.
Paying down unnecessary debt before applying can sometimes improve your overall lending position. However, consider your wider financial position before making large repayments or closing accounts.
3. How Much Loan Can I Borrow Under the 2026 DTI Rules?
Debt-to-income, or DTI, is an important part of the New Zealand lending environment in 2026. The Reserve Bank introduced DTI restrictions for banks’ residential lending from 1 July 2024.
For owner-occupiers, borrowing above six times annual gross income is considered high-DTI after taking existing debt into account. Banks can have up to 20% of their new owner-occupier lending above the DTI threshold. For investors, the threshold is generally seven times annual gross income, with a 20% speed limit for high-DTI lending.
A Simple DTI Example
Imagine a household has a combined gross income of $150,000 a year and no existing debt.
Six times the gross income would be:
$150,000 × 6 = $900,000
This does not mean the household automatically qualifies for a $900,000 mortgage. DTI is only one part of the assessment, and banks also consider existing debt and their own affordability criteria.
For example, if a household earning $150,000 already had $50,000 of debt, the high-DTI reference point would be different because existing debt is included in the calculation.
So, if you are searching for how much loan can I borrow, do not use six times your income as a guaranteed mortgage calculator. Treat DTI as one part of the wider lending assessment.
4. Your Deposit Can Change How Much You Need to Borrow
Your deposit is another major factor when working out how much loan can I borrow. The larger your deposit, the less you need to borrow for the same property price.
For example:
| Home price | Deposit | Loan required |
|---|---|---|
| $600,000 | $120,000 | $480,000 |
| $700,000 | $140,000 | $560,000 |
| $800,000 | $160,000 | $640,000 |
| $900,000 | $180,000 | $720,000 |
These examples assume a 20% deposit and do not represent guaranteed lender approval.
The Reserve Bank’s LVR guidance explains how loan-to-value ratios work and why banks consider the amount borrowed compared with the property value.
Can I Borrow With a Smaller Deposit?
You may be able to borrow with less than a 20% deposit, depending on your circumstances and the lender. However, low-deposit lending can have additional requirements and costs.
As of the current 2026 settings, banks can have up to 25% of new owner-occupier lending above 80% LVR. For investors, the corresponding limit is 10% of new lending above 70% LVR.
These are limits on banks’ lending portfolios, not guarantees that an individual applicant can borrow with a particular deposit. Each bank still applies its own lending criteria.
5. First Home Buyers May Have More Options
If you are a first home buyer, your deposit and available government-supported options can affect how much loan can I borrow.
Eligible buyers may be able to use a First Home Loan through Kāinga Ora, which can reduce the required deposit to 5% through participating lenders. Eligibility criteria and lender approval apply.
You can check the latest requirements on the official Kāinga Ora First Home Loan page.
A 5% deposit can reduce the amount you need to save before buying, but it does not automatically increase the amount a bank will lend you.
For example:
$700,000 property × 5% deposit = $35,000 deposit
Potential loan = $665,000
The actual loan amount still depends on your income, expenses, debts, lender criteria and approval.
If you are a first home buyer, you can also read our GM Finance guide to first home buyer mortgage options in New Zealand.
6. Your Monthly Expenses Matter
Your income does not tell the whole story when working out how much loan can I borrow. Lenders also need to understand your regular household spending.
Your expenses may include:
- Groceries
- Power
- Internet
- Mobile phones
- Transport
- Insurance
- Rates
- Childcare
- School costs
- Entertainment
- Existing repayments
- Other regular commitments
A household earning $120,000 with high monthly commitments may have a different borrowing capacity from a household earning $120,000 with lower commitments.
Why Your Spending Habits Matter
Your bank statements can help show your actual spending patterns. Regular financial commitments and discretionary spending can affect the lender’s assessment of your ability to service a mortgage.
This is why preparing your finances before applying can be useful.
7. Your Credit History Can Affect Your Application
Your credit history is another factor to consider when asking how much loan can I borrow. Lenders may review your credit information when assessing an application.
Before applying, consider:
- Paying bills on time
- Reducing unnecessary debt
- Avoiding missed repayments
- Keeping credit card balances manageable
- Avoiding unnecessary new credit applications
- Checking your credit information for errors
A credit history issue does not always mean you cannot obtain a home loan, but it may affect the lender options available to you.
8. Your Property Value and LVR Can Affect the Loan
The property itself also matters when calculating how much loan can I borrow. Lenders consider the property value and the amount you want to borrow against it.
What Is LVR?
LVR stands for loan-to-value ratio. It compares your mortgage with the value of the property.
For example:
Property value: $800,000
Mortgage: $640,000
LVR: 80%
A lower LVR means you have more equity in the property relative to your mortgage.
The Reserve Bank’s current settings allow banks to have up to 25% of new owner-occupier lending above 80% LVR and up to 10% of new investor lending above 70% LVR.
These settings do not mean every borrower can obtain an 80%, 90% or 95% LVR mortgage. Your bank still makes an individual lending decision.
For more detail, see the Reserve Bank of New Zealand’s LVR explainer.
9. Interest Rates Also Affect How Much You Can Afford
Interest rates affect your mortgage repayments, which is why they matter when calculating how much loan can I borrow.
A larger mortgage means that changes in interest rates can have a larger impact on your repayments.
This is why you should look at the repayment amount rather than focusing only on the maximum loan figure.
A mortgage that a lender is willing to approve may still be larger than the amount you personally feel comfortable repaying.
You can also read the GM Finance guide on fixed versus floating home loan rates to understand how different loan structures can affect your mortgage.
How Much Loan Can I Borrow Based on My Income?
There is no universal income-to-loan formula that guarantees approval, but simple examples can help you understand the numbers.
For an owner-occupier with no existing debt, the six-times-income figure can be used as a DTI threshold reference, not as a guaranteed borrowing amount.
| Gross household income | 6 × income | DTI reference point* |
|---|---|---|
| $80,000 | $480,000 | $480,000 |
| $100,000 | $600,000 | $600,000 |
| $120,000 | $720,000 | $720,000 |
| $150,000 | $900,000 | $900,000 |
| $180,000 | $1,080,000 | $1,080,000 |
| $200,000 | $1,200,000 | $1,200,000 |
*These are simplified examples assuming no existing debt. They are not borrowing limits or loan approvals.
The DTI threshold is not a mortgage calculator. Existing debt, deposit, expenses, interest rates and the lender’s affordability assessment all matter.
How Much Loan Can I Borrow With a 20% Deposit?
A 20% deposit is a useful starting point for understanding the relationship between your deposit, property price and mortgage.
For example:
$100,000 deposit
If that represents 20% of the purchase price:
Estimated purchase price = $500,000
Estimated mortgage = $400,000
Another example:
$150,000 deposit
At 20%:
Estimated purchase price = $750,000
Estimated mortgage = $600,000
However, your borrowing capacity still needs to support the mortgage repayments. Having a 20% deposit does not automatically mean a lender will approve the maximum loan calculated from that deposit.
How Much Loan Can I Borrow With a 10% Deposit?
A 10% deposit means you would need to borrow approximately 90% of the property’s value if the lender approves that LVR.
For example:
$70,000 deposit + $630,000 mortgage = $700,000 property
This is an example only. Low-deposit lending depends on the lender’s criteria and the bank’s available high-LVR lending capacity.
The current Reserve Bank settings allow some high-LVR owner-occupier lending, but individual banks decide which applications they approve.
What Documents Do I Need to Work Out How Much I Can Borrow?
Having your financial information ready can make the borrowing assessment easier.
You may need:
- Recent payslips
- Employment information
- Bank statements
- Evidence of savings
- KiwiSaver information
- Details of existing debts
- Credit card information
- Personal loan statements
- Identification
- Property information
- Business financial statements if self-employed
Your lender or mortgage adviser can tell you exactly what documents are required for your circumstances.
Mortgage Pre-Approval: A Better Way to Find Out How Much You Can Borrow
If you want a more accurate answer to how much loan can I borrow, mortgage pre-approval is an important step.
Pre-approval involves an initial assessment of your financial position and can give you an indication of the amount a lender may be prepared to lend, subject to conditions.
Pre-approval is not the same as final approval. The property you eventually choose may still need to meet the lender’s requirements.
You can read the official Kāinga Ora guide to preparing and applying for home ownership for more information.
For a more detailed explanation, see the GM Finance guide to mortgage pre-approval.
How Can I Increase How Much I Can Borrow?
If your initial borrowing capacity is lower than expected, there are several areas you can review.
Reduce Existing Debt
Reducing personal loans, credit card balances and other debts can improve your overall financial position.
Increase Your Deposit
A larger deposit means you need to borrow less for the same property price.
Review Your Expenses
Reducing unnecessary ongoing commitments can improve the amount of income available for mortgage repayments.
Avoid New Debt Before Applying
Taking on a new car loan or increasing credit card commitments shortly before applying can affect your borrowing position.
Build Stable Income
Stable and well-documented income can make it easier for a lender to assess your financial position.
Get Professional Advice
A mortgage adviser can help you understand how different lenders may assess your circumstances and what information you need to prepare.
How Much Loan Can I Borrow If I Have Other Debt?
Having existing debt does not automatically prevent you from getting a home loan, but it can reduce your borrowing capacity.
For example, imagine you have:
- $10,000 credit card balance
- $15,000 car loan
- $20,000 personal loan
Your lender may consider these commitments when assessing your ability to service a new mortgage.
The impact depends on the type of debt, repayments, lender criteria and your wider financial position.
This is why it can be useful to review your debts before applying rather than simply calculating a mortgage based on income alone.

Final Thoughts: How Much Loan Can I Borrow in 2026?
The answer to how much loan can I borrow depends on much more than your salary. Your deposit, debts, expenses, credit history, property value, LVR, DTI and the lender’s own assessment all play a role.
The 2026 lending environment includes DTI and LVR restrictions that affect how banks manage residential mortgage lending. These rules do not create a guaranteed borrowing amount for individual applicants.
If you are planning to buy a home, start with your numbers rather than the property price. Understanding your borrowing capacity can help you search within a realistic budget and avoid wasting time on properties outside your likely finance range.
Mortgage pre-approval can then give you a clearer indication of how much you may be able to borrow before you make an offer.
