Deciding to Sell Your Home
🏠 The Decision Before the Decision
Most selling advice starts at the point where you have already decided to sell and only need to know how. That skips the more expensive question, which is whether moving is worth what it costs. A move is not free even when the sale goes perfectly, and the costs land on both sides: the sale you are making and the purchase you are probably making after it.
Reasons that usually survive the arithmetic
- A change in what the house has to do: a child arriving, a parent moving in, a job in another city.
- A house that no longer suits and cannot be made to suit without spending more than moving would cost.
- Releasing equity you actually need, rather than equity you would like to look at.
- A commute or a school zone that is costing you time every day rather than money once.
Reasons that often do not
Moving because the market is said to be good is the most common one, and it is weaker than it sounds. If you sell high you usually buy high in the same market on the same day, and the gain you captured on the sale is spent on the purchase. The exception is when you are moving between markets that are genuinely different, or leaving the market entirely.
💰 The Real Cost of Moving
Before anything else, put a number on the round trip. This is not the sale price and it is not the purchase price. It is everything that leaves your hand between deciding to move and being settled in the next house.
| Cost | Falls on | Note |
|---|---|---|
| Agent commission | The sale | Only if you use an agent, and it is negotiable |
| Marketing and advertising | The sale | Usually paid by you whether or not the house sells |
| Legal fees, selling | The sale | Conveyancing, discharging your mortgage |
| Legal fees, buying | The purchase | Conveyancing, registering a new mortgage |
| Repairs and presentation | The sale | From a tidy-up to staging |
| Break cost on a fixed loan | The sale | Depends on rates and time remaining |
| Moving costs | Both | Removals, storage, connections |
| Overlap or gap | Both | Bridging finance or temporary accommodation |
Two of these are the ones people leave out. A break cost on a fixed mortgage can be substantial, and it is calculated by your lender against the rates on the day rather than by a formula you can look up. Ring them and ask for the figure before you list. The other is the gap: if you settle your sale before your purchase, you have to live somewhere, and if you settle your purchase first you have to fund it.
Work the whole picture through with the cost of selling a house calculator, which puts the sale side in one place.
🔄 Sell First or Buy First
If you are moving from one home to another, this is the decision that carries the most risk, and there is no answer that is right for everyone. Each order protects you from one problem and exposes you to the other.
What selling first protects you from
You are negotiating your purchase with a known budget and a known settlement date, which is a strong position. You cannot end up owning two houses. The cost is timing: if the purchase takes longer than the sale, you need somewhere to live and somewhere to put your things.
What buying first protects you from
You are not homeless and not rushed into an unsuitable house. The cost is exposure: you have committed to a price before you know what your own house will fetch, and if the sale comes in below expectations the shortfall is yours to fund. Bridging finance exists for this and is not free.
Compare the two orders on your own figures with the sell first vs buy first calculator.
📅 Timing, and What Nobody Can Tell You
There is a persistent belief that there is a right month to sell. Listing volumes do move through the year in New Zealand, and spring is traditionally busier, but a busier market has more buyers and more competing houses at the same time. The two partly cancel.
Timing that does matter
- How long your finances can carry two properties, or none.
- When your fixed mortgage term ends, because breaking early has a cost.
- School terms, if a move means changing schools.
- How long you have owned the property, because of the bright-line rules covered in the tax step.
That last one is worth checking before you list rather than after you have accepted an offer. See the bright-line test guide.
✅ Before You Speak to Anyone
Once you invite an agent to appraise the house, you are in a sales process, and the first document in front of you may be an agency agreement. Everything below is easier to do before that point.
- Get the break cost figure from your lender in writing.
- Work out your rough net proceeds, not your expected sale price.
- Decide whether you are selling first or buying first, and why.
- Check the bright-line position for your ownership period.
- Find your title, any consents for work you have done, and your LIM if you have one.
Next in this pathway: what selling actually costs, then the choice between selling privately and using an agent.
