Buying a $700,000 property in New Zealand requires a clear understanding of the income required under the RBNZ’s DTI rules, the deposit you need, and what your repayments will look like month to month.
To buy a $700,000 home in NZ with a standard 20% deposit ($140,000), you need a gross annual income of at least $93,333 under DTI 6x. Monthly repayments on the $560,000 loan at 5.50% over 30 years are approximately $3,180/month. The bank serviceability stress test at ~7.5-8.5% may set a different limit depending on your expenses and other debts.
The Numbers at a Glance
| 20% deposit | 10% deposit | |
|---|---|---|
| Deposit required | $140,000 | $70,000 |
| Loan amount | $560,000 | $630,000 |
| Min gross income (DTI 6x) | $93,333 | $105,000 |
| Monthly repayment (5.50%, 30yr) | $3,180 | $3,577 |
| Weekly repayment (5.50%, 30yr) | $734 | $825 |
First Home Loan: If you qualify (income limits and property price caps apply), the First Home Loan requires only a 5% deposit — reducing the cash needed to $35,000 but increasing your monthly repayment to approximately $3,776/month at 5.50%.
Minimum Income Required
Under the RBNZ’s DTI limit of 6x gross annual income, the minimum income needed to service a $700,000 purchase is:
With a 20% deposit ($140,000):
- Loan amount: $560,000
- Minimum gross income: $560,000 / 6 = $93,333 per year
With a 10% deposit ($70,000):
- Loan amount: $630,000
- Minimum gross income: $630,000 / 6 = $105,000 per year
These are DTI floors only. Student loans, car loans, and credit card limits all reduce borrowing capacity — meaning you may need a higher income if you carry any existing debt.
The bank’s serviceability stress test at approximately 7.5%–8.5% may be the binding constraint for some borrowers with high living expenses.

Saving the Deposit
Saving a 20% deposit of $140,000 is the biggest challenge for most first home buyers. Realistic timelines at different weekly savings rates:
| Weekly savings | Months to reach $140,000 |
|---|---|
| $300/week | 108 months (9.0 years) |
| $500/week | 65 months (5.4 years) |
| $750/week | 43 months (3.6 years) |
| $1,000/week | 32 months (2.7 years) |
KiwiSaver contributions count toward your deposit — a first home withdrawal can provide $15,000–$60,000+ depending on your balance, significantly accelerating the timeline.
What Does $700,000 Buy in NZ?
At $700k you can access most Christchurch and Hamilton properties. You’re approaching the Wellington median (~$750k). Auckland remains expensive — $700k buys a smaller townhouse or unit in the outer suburbs.
Affordability at the Minimum Income
At $93,333 gross income (the DTI minimum) with a $3,180/month mortgage:
- Monthly gross income: $7,778
- Mortgage as % of gross income: 40.9%
- Adding rates (~$400/month) and insurance (~$250/month): 49.2% of gross income
At the DTI minimum, housing is expensive relative to income. A higher income or larger deposit significantly improves cashflow comfort.
