What's the best bank for a home loan if you're self-employed and have been in business for three years?
Best home loan banks in New Zealand if you're self-employed for 3 years
If you've been self-employed for three years in New Zealand, I'd start by comparing BNZ, ASB, ANZ and Westpac, rather than assuming one bank will be best. Your three-year business history can be an advantage because you may have enough financial records to demonstrate consistent income.
The key is finding a lender that assesses self-employed income fairly, offers a suitable interest rate, and is comfortable with how you earn your money.
Which banks should you approach first?
| Bank | Why it's worth considering | What you'll generally need |
|---|---|---|
| BNZ | A good starting point if you have a solid financial track record. | Your last two annual business financial statements. BNZ home loan requirements. |
| ASB | Worth comparing if you have consistent income and well-prepared accounts. | Your latest accountant-prepared financial statements and evidence of your deposit. ASB application guide. |
| ANZ | Worth considering if your business income is straightforward to document. | Financial statements, preferably prepared through your accountant. ANZ application guide. |
| Westpac | Another strong option for comparing lending terms and interest rates. | Your latest accountant-prepared financial statements. Westpac application guide. |
These banks all assess self-employed applicants, but their individual lending criteria and assessment of your income may differ. The documentation requirements above are based on their published guidance. Sources: BNZ, ASB, ANZ and Westpac.
What matters most when you're self-employed?
Having been in business for three years is a good starting point, but lenders will generally look at several other factors.
- Your net profit: How much income your business generates after expenses, rather than just its turnover.
- Consistency of earnings: Whether your profits have increased, stayed steady or declined over the last two financial years.
- Your business structure: Whether you're a sole trader, a contractor, or a director of a limited company.
- Your deposit: A 20% deposit can make the application more straightforward, although other options may be available.
- Your existing debts: Personal loans, credit cards, vehicle finance and business liabilities can affect your borrowing capacity.
For example, if your company earns $250,000 in annual revenue but generates only $70,000 in net profit, the bank won't necessarily treat you as earning $250,000.
Similarly, if you own a company and pay yourself a relatively small salary while retaining profits in the business, the way the lender assesses that income can make a significant difference.
My recommendation: Talk to a mortgage adviser
For someone who has been self-employed for three years, I'd seriously consider speaking to an independent mortgage adviser before applying directly to several banks.
An adviser can compare lenders, help establish which banks are likely to accept your income structure, and present your financial situation appropriately.
This can be especially valuable if:
- Your income fluctuates from year to year.
- You retain profits in your company.
- You have a relatively small deposit.
- Your latest financial year was significantly better than the previous one.
The aim is to identify the lender most likely to offer you a suitable loan, not simply the bank advertising the lowest interest rate.
Let me narrow it down to the best bank for you
I can give you a more specific recommendation if you tell me three things.
1. How do you operate your business?
- A. Sole trader
- B. Limited company (you pay yourself a salary)
- C. Limited company (you mainly take drawings or dividends)
- D. Contractor or self-employed professional
2. Roughly how much do you earn per year before personal tax?
Your personal income or average annual profit is fine; an approximate figure is all I need.
3. How much deposit do you have?
- A. Less than 10%
- B. 10–19%
- C. 20–29%
- D. 30% or more
With those answers, I can help you work out which New Zealand banks I'd approach first and which aspects of your application are likely to matter most.
