How an Accountant Can Help Prepare Your Finances for a Mortgage Application in NZ
Preparing for a mortgage application in New Zealand? Before approaching a lender or mortgage adviser, it can help to have your financial information organised, accurate and ready to provide.
An accountant can help you prepare and review financial information such as financial statements, income records, tax information, business accounts and supporting documents that may be requested during a mortgage application.
At DFK Orb360 O’Halloran , we help business owners, self-employed professionals and other clients organise and understand their accounting and financial information when preparing for significant financial applications.
Quick Answer: Can an Accountant Help With a Mortgage Application?
Yes. An accountant can help organise and prepare financial information such as financial statements, income records, tax information, business accounts and supporting documents that may be required for a mortgage application.
However, accountants and mortgage advisers have different roles. A mortgage adviser provides advice about home loans and lending products, while an accountant can help prepare and explain accounting and financial information.
Why Your Financial Information Matters When Applying for a Mortgage
When you apply for a mortgage, a lender may request information about your income, expenses, assets, liabilities and overall financial position.
The exact documents required can vary depending on the lender, your circumstances and whether you are employed, self-employed or operating through a business.
For business owners and self-employed applicants, financial information can involve multiple records and income sources. Having these records organised can make it easier to respond when financial information is requested.
Your mortgage adviser or lender can tell you what information they require for your particular application. Your accountant can help you prepare relevant accounting information.
What Financial Information May Be Needed for a Mortgage Application?
Requirements vary between lenders and applicants. Depending on your circumstances, you may be asked for information such as:
- Personal income information
- Business income information
- Profit and loss statements
- Balance sheets
- Financial statements
- Tax returns and tax information
- Business bank records
- Details of existing debts and liabilities
- Evidence supporting income or business earnings
- Information about assets and business interests
- Other supporting documents requested by the lender
Always confirm the exact documentation requirements with your lender or mortgage adviser.
How an Accountant Can Help Prepare You for a Mortgage Application
1. Prepare Up-to-Date Financial Statements
If you operate a business, an accountant can help prepare or update financial statements that show the financial position of the business.
Depending on your circumstances, this may include a profit and loss statement and balance sheet.
Having current financial information available can make it easier to respond when a lender or mortgage adviser requests supporting documentation.
2. Review Your Income Information
Income can be more complex for business owners and self-employed individuals than for someone receiving a regular salary or wage.
An accountant can help identify and organise relevant income information from your accounting records and explain how different figures are reflected in your financial statements.
This does not mean an accountant determines how a lender will assess your income. The lender decides what income it recognises and what documentation it requires.
3. Organise Business Financial Records
If you operate a company, partnership or other business structure, you may have several financial records that need to be brought together.
An accountant can help organise relevant records and identify missing or outdated information before documents are provided for a mortgage application.
4. Check That Your Records Are Consistent
Inconsistencies between financial statements, tax information, accounting records and supporting documents can result in additional questions during an application.
Reviewing your records beforehand can help identify information that may require clarification or correction.
5. Help Explain Your Business Financial Position
Business owners may have income, expenses, drawings, shareholder salaries, company structures or other accounting considerations that are not immediately obvious from a single bank statement.
Your accountant can help explain the accounting information and provide relevant supporting documentation where appropriate.
6. Help You Understand What Your Financial Records Show
Preparing for a mortgage application can also be an opportunity to understand your current financial position.
Your accountant can help you understand figures such as business revenue, expenses, profitability, assets and liabilities based on your accounting records.
Mortgage Applications for Self-Employed People in NZ
Self-employed applicants may have additional financial information to organise because their income can come through a business rather than a standard salary or wage.
If you are self-employed, preparing your accounting records before beginning a mortgage application may help you respond more efficiently when financial documents are requested.
An accountant can assist with areas such as:
- Preparing current financial statements
- Reviewing business income and expenses
- Organising tax information
- Reviewing business and personal financial records
- Preparing supporting accounting information
- Identifying discrepancies that may need clarification
The lender or mortgage adviser will determine which documents are required and how the information is assessed.
What If You Are a Business Owner Applying for a Mortgage?
Business owners may need to provide information from both their business and personal financial position.
Your financial circumstances may involve:
- Company income
- Shareholder salary
- Drawings
- Business expenses
- Existing business debt
- Personal lending
- Property investments
- Multiple income sources
Because every applicant’s circumstances are different, the documents required will depend on the lender’s requirements and individual circumstances.
Accountant vs Mortgage Adviser: What’s the Difference?
Understanding the difference between these services is important when preparing for a mortgage application.
| Accountant | Mortgage Adviser |
|---|---|
| Helps prepare and explain accounting and financial information | Provides advice about home loans and lending products |
| Prepares financial statements and accounting records | Advises on lending options within their authorised scope |
| Helps organise tax and business financial information | Can work with lenders during the mortgage process |

When Should You Speak to Your Accountant?
You do not necessarily need to wait until a lender or mortgage adviser requests your documents.
If you are considering applying for a mortgage, speaking with your accountant beforehand can help you understand whether your financial records are current and properly organised.
This can be particularly relevant if:
- You are self-employed
- You own a company
- You are a property investor
- Your income comes from multiple sources
- Your latest financial statements are outdated
- Your business has recently changed
- You are preparing for a significant lending application

Can an Accountant Improve My Chances of Getting a Mortgage?
An accountant cannot guarantee mortgage approval or determine whether a lender will approve an application.
What an accountant can do is help ensure that accounting and financial information is accurate, organised and appropriately prepared for the information requirements of your application.
The final lending decision belongs to the lender, based on its own lending criteria and assessment process.
