Buying a home is one of the biggest financial commitments most people will ever make. Whether you’re purchasing your first property, upgrading to a larger home, or investing in real estate, getting approved for a home loan is one of the most important steps in the process.
Many borrowers assume home loan approval is based only on income, but lenders evaluate a wide range of financial and personal factors before making a decision. Understanding what lenders look for can help you prepare a stronger application, improve your chances of approval, and potentially secure better loan terms.
In this guide, we’ll explain the top factors lenders consider when approving a home loan and how you can position yourself for success.
1. Your Income and Employment Stability
One of the first things lenders assess is your income. They want to ensure you earn enough to comfortably manage mortgage repayments while still covering your daily living expenses.
Lenders usually review:
- Salary or wages
- Self-employed income
- Rental income
- Bonuses or commissions
- Secondary income sources
Stable employment is also important. Borrowers with long-term or consistent employment history are often viewed as lower risk.
What Lenders Prefer
- Full-time permanent employment
- Consistent income over time
- Stable industry or occupation
- Reliable employment history
If you’re self-employed, lenders may request additional documents such as tax returns and financial statements to verify your income.
2. Your Deposit Size
Your deposit plays a major role in home loan approval. The larger your deposit, the lower the lender’s risk.
Traditionally, lenders prefer a 20% deposit, but some buyers may qualify with lower deposits depending on lender criteria and eligibility.
Benefits of a Larger Deposit
- Better approval chances
- Lower interest rates
- Reduced borrowing costs
- Increased borrowing power
For first home buyers, deposit sources may include:
- Personal savings
- KiwiSaver withdrawal
- Gifts from family
- Sale of existing assets

3. Your Credit History
Your credit history helps lenders understand how you’ve managed debt and repayments in the past.
Lenders typically review:
- Credit card repayment history
- Personal loan records
- Missed or late payments
- Defaults or collections
- Current credit limits
A strong credit profile demonstrates financial responsibility and can improve your chances of approval.
Tips to Improve Your Credit Score
- Pay bills on time
- Reduce outstanding debts
- Avoid unnecessary credit applications
- Keep credit card balances low
Even small improvements to your credit profile can make a positive difference.
4. Existing Debts and Financial Commitments
Lenders carefully examine your current financial obligations before approving a mortgage.
These may include:
- Credit cards
- Car loans
- Personal loans
- Buy-now-pay-later services
- Student loans
High existing debt may reduce your borrowing power because lenders need to ensure you can comfortably manage additional repayments.
Why Debt Matters
The more debt you already have, the higher your debt-to-income ratio becomes. This may affect:
- Loan approval amount
- Interest rates offered
- Overall affordability assessment
Reducing unnecessary debt before applying for a home loan can strengthen your application significantly.
5. Your Spending Habits
Many borrowers are surprised to learn that lenders review everyday spending habits during the application process.
Bank statements may be assessed for:
- Entertainment expenses
- Gambling transactions
- Subscription services
- Dining and takeaway spending
- Shopping patterns
Lenders want to understand how you manage money on a regular basis.
How to Improve Financial Behaviour
- Create a realistic budget
- Reduce unnecessary expenses
- Increase savings consistency
- Avoid large discretionary purchases before applying
Responsible financial habits show lenders you can manage mortgage repayments effectively.
6. Loan Affordability and Serviceability
Lenders need to determine whether you can comfortably repay the mortgage not only today but also in the future.
This process is known as serviceability assessment.
Lenders calculate:
- Your total household income
- Existing expenses
- Debt obligations
- Estimated mortgage repayments
They may also test whether you could still afford repayments if interest rates increase.
Why This Matters
Even if you qualify for a large loan amount, lenders want to ensure you won’t face financial hardship later.
Good serviceability improves:
- Approval chances
- Loan flexibility
- Long-term financial stability
7. Type and Value of the Property
The property itself also plays a role in mortgage approval.
Lenders consider:
- Property location
- Property condition
- Market value
- Type of property
- Future resale potential
Some properties may be considered higher risk, including:
- Small apartments
- Rural properties
- Unusual construction types
- Properties requiring major repairs
A professional property valuation may be required before final approval.
8. Loan-to-Value Ratio (LVR)
Loan-to-Value Ratio (LVR) compares the amount you borrow to the value of the property.
For example:
- Property value: $800,000
- Loan amount: $640,000
- LVR: 80%
Lower LVRs are generally viewed more favourably by lenders because they reduce lending risk.

9. Your Savings History
Consistent savings demonstrate financial discipline and responsible money management.
Lenders often like to see:
- Regular deposits into savings accounts
- Genuine savings over time
- Stable account balances
Strong savings habits indicate that you may be able to manage mortgage repayments responsibly.
10. Your Loan Purpose
The reason for your home loan can also influence lender decisions.
Common loan purposes include:
- Owner-occupied property
- Investment property
- Renovation funding
- Refinancing existing debt
Investment property loans may involve stricter lending requirements because they are often viewed as higher risk compared to owner-occupied homes.
11. Interest Rates and Loan Structure
Lenders also review the type of mortgage structure you choose.
Options may include:
- Fixed-rate loans
- Floating-rate loans
- Split loans
Each option affects:
- Repayment stability
- Financial flexibility
- Long-term affordability
Choosing a suitable loan structure demonstrates financial planning and understanding.
12. Documentation and Accuracy
Providing accurate and complete documentation is essential for smooth mortgage approval.
Commonly required documents include:
- Identification
- Proof of income
- Bank statements
- Tax returns
- Existing loan details
- Property information
Missing or inconsistent information can delay the approval process.
Common Mistakes That Can Affect Approval
Many borrowers unknowingly weaken their applications before applying for a mortgage.
Common mistakes include:
- Applying for multiple loans or credit cards
- Changing jobs during the application process
- Missing bill payments
- Overspending before approval
- Taking on new debt
Avoiding these mistakes can improve your chances of success.
How a Mortgage Advisor Can Help
Navigating the home loan process alone can feel stressful and time-consuming. A mortgage advisor can simplify the process and help you make informed decisions.
A finance specialist can assist with:
- Comparing lenders and rates
- Understanding loan structures
- Improving application strength
- Managing paperwork efficiently
- Finding suitable mortgage solutions
Professional advice can save time, reduce stress, and potentially improve approval outcomes.
Final Thoughts
Getting approved for a home loan involves much more than simply earning an income. Lenders assess your financial position, deposit size, debts, spending habits, savings history, and overall ability to manage repayments responsibly.
The better prepared you are before applying, the stronger your chances of approval become. Improving your financial habits, reducing debt, maintaining stable employment, and seeking professional guidance can all make a significant difference.
Whether you’re a first home buyer or refinancing an existing mortgage, understanding what lenders look for can help you move forward with greater confidence.
