We need a bigger home for our family, but haven't sold our current place. Is it safer to sell first, or can we look at buying before we sell?
For most families in New Zealand who need a bigger home but haven't sold their current one, selling first is usually the safer financial option, but buying first can work if you have enough equity, borrowing capacity and a clear backup plan.
The real question is how much risk your family can comfortably carry while owning two homes, and whether you can afford the next home without relying on your current property selling for a particular price by a particular date.
Your three main options
1. Sell first — lowest financial risk
You sell your current home, know how much money you'll have available, and then buy your next property.
- Advantages: Clear budget, less financial pressure and no risk of carrying two mortgages for long.
- Trade-offs: You may need temporary accommodation, storage or a short-term rental, and you could feel rushed to find your next home.
- Best for: Families who need certainty about their deposit and maximum budget.
2. Buy first, then sell — more flexibility, more risk
You secure the bigger home before putting your existing property through the selling process.
- Advantages: You can move directly into your new home, avoid moving twice and take advantage of a property you really want.
- Trade-offs: You may need to fund two mortgages, rates, insurance and maintenance. If your existing home sells for less than expected or takes longer to sell, the pressure can build quickly.
- Best for: Families with strong financial reserves, sufficient borrowing capacity and a realistic plan for selling the current home.
3. Buy conditionally or coordinate settlement — often a useful middle ground
You find your next home while negotiating a purchase that depends on conditions being met, or arrange settlement dates to give yourself time to sell.
- Advantages: You may secure a suitable home without committing immediately to an unconditional purchase.
- Trade-offs: A seller may prefer an unconditional offer, and conditions and settlement dates need careful negotiation.
- Best for: Families who want to explore the market without taking on unnecessary financial risk.
What I'd recommend doing first
Before you decide whether to sell, take these four steps:
- Get a realistic sale estimate. Ask an agent for a likely selling range, not just an optimistic appraisal. Allow for agent commission, legal fees, marketing and any mortgage repayment costs.
- Ask your bank or mortgage adviser to model both scenarios. Find out what you can borrow before selling, whether bridging finance is available, and how long you could afford two sets of housing costs. Bridging finance has risks and costs, even if the loan is interest-only. Thinking about your finances when sellingBridging finance - Buying & selling at the same time
- Explore buying with conditions. You may be able to make an offer subject to selling your existing home, obtaining finance or completing other checks. Get a lawyer to review the conditions before signing. Understanding the sale and purchase agreement when buyingBuying by deadline
- Work out your worst-case budget. Assume your current home sells for less than expected and takes several months longer than hoped. If that would put your family under serious financial pressure, selling first is likely the better choice.

Let's work out which option suits your family
The biggest factor is how much equity you have in your current home and whether you need that money to buy the next one.
If you're comfortable sharing some rough figures, I can help you compare the options.
Estimates are fine. Use NZ dollars.
With those figures, we can estimate how much equity you might release, how large the next mortgage could be, and whether buying before selling looks manageable or unnecessarily risky. These would be planning estimates, not a substitute for lender approval.
