My partner and I want to buy our first home. We both have salaried jobs and about a 10% deposit. Are we ready to start talking to banks, or should we keep saving?
My advice: start talking to banks now, while continuing to save. You don't necessarily need to wait until you've saved a 20% deposit before exploring your options.
As a first-home-buying couple in New Zealand, with two salaried incomes and around a 10% deposit, you're in a reasonable position to start finding out what you can afford. Whether you're ready to buy will depend on your combined income, existing debts, regular expenses, the size of your deposit and the property you're considering.
The goal at this stage isn't necessarily to get a mortgage immediately. It's to understand what a bank might lend you, what your repayments would look like, and whether waiting longer would put you in a stronger position.
1. Why a 10% deposit can be enough to start
In New Zealand, many banks prefer a 20% deposit, but they can lend to some owner-occupiers with smaller deposits. There are limits on how much low-deposit lending banks can do, so approval isn't guaranteed.

Here are the main options worth exploring:
- Buy with a 10% deposit: Ask banks whether they have low-deposit lending available for your circumstances.
- Check whether you're eligible for a First Home Loan: This Kāinga Ora-supported scheme can allow eligible buyers to purchase with a 5% deposit. Income and other eligibility criteria apply.

- Use KiwiSaver: If eligible, you may be able to withdraw your KiwiSaver savings for your first home, provided at least $1,000 remains in your account. KiwiSaver first-home withdrawal :: Kāinga Ora
2. What the bank will actually look at
Having two salaried incomes is helpful, but lenders will assess your overall financial position.
| What they'll assess | What you should aim for |
|---|---|
| Combined income | Stable, documented income from both jobs |
| Existing debt | Keep credit-card limits, personal loans and car loans manageable |
| Spending | Show that you can comfortably cover expenses and save regularly |
| Deposit | Have evidence of your savings and any eligible KiwiSaver withdrawals |
| Repayments | Be comfortable with repayments even if interest rates rise |
| Cash buffer | Retain money for legal fees, inspections, moving and unexpected repairs |
Banks also operate under debt-to-income restrictions, which can limit lending when borrowing is high relative to gross household income. Understanding debt-to-income (DTI) restrictions - Reserve Bank of New Zealand
One important point: Don't assume that the maximum amount a bank is willing to lend is the amount you should borrow.
3. Should you save to 20% first?
I'd weigh it up like this.
Talk to banks now
Find out your potential borrowing limit, whether they'll consider a 10% deposit, what interest rates and low-equity costs may apply, and whether you qualify for any first-home assistance.
Keep saving in parallel
A larger deposit reduces the amount you need to borrow and may give you access to better lending terms. It also helps preserve a cash buffer after settlement.
Buy when the numbers work
You don't need to wait for 20% if a suitable loan is available and the repayments are genuinely affordable for you both.
You can start with a mortgage adviser or a bank's home-loan team. A conditional pre-approval can help establish a realistic price range, although the lender will still need to approve the specific property and confirm the loan before settlement. Confirming your finances
4. Let's work out whether you're close
If you share a few approximate numbers, I can help you estimate whether buying now looks realistic or whether another 6–12 months of saving could put you in a much stronger position.
Approximate figures are fine. Use NZ dollars and annual income before tax.
With those figures, we can look at the trade-off between buying sooner with a 10% deposit and waiting to build a bigger deposit, rather than assuming that one option is automatically better.
