How to Best Negotiate a Private Treaty Sale

A private treaty sale is one of the most common ways property is bought and sold in New Zealand. The home is marketed with an asking price (or price guide), buyers submit written offers and the seller decides whether to accept, reject or negotiate.

Unlike an auction, private treaty gives you room to negotiate, but it can move quickly, especially in popular suburbs or when stock is tight. Here’s how to approach a private treaty negotiation with confidence, clarity and the best chance of success.

What is a private treaty sale?

In a private treaty sale, the property is listed with an asking price and buyers make offers through the real estate agent. The agent presents each offer to the seller. Negotiations may go back and forth until both sides agree on price and terms.

It’s straightforward in theory but in practice, the “best” offer isn’t always just the highest number. Conditions, settlement dates and buyer certainty all play a major role.

How to negotiate a deal before someone else does

1. Understand the market before you name a price

Before you decide what to offer, do your research:

• Compare recent sales of similar properties in the area (not just current listings).
• Ask the agent what level of interest there has been (enquiries, groups through, other offers).
• Consider how long the property has been on the market—fresh listings often attract stronger competition.

The better informed you are, the easier it is to make an offer that’s realistic and defensible.

2. Decide your strategy: strong first offer vs “start low”

One of the hardest decisions is whether to start with your best offer or begin lower and negotiate upward.

• A strong first offer can be smart when there’s high interest or the property is likely to attract multiple offers.
• Starting lower can work when the property has been sitting on the market or the seller’s expectations appear flexible, but it carries a risk: another buyer may come in stronger and you won’t get a second chance.

A good rule: if you’d be genuinely upset to lose the property, don’t “test the waters” with an offer you wouldn’t accept if roles were reversed.

3. Find out what matters most to the seller (price isn’t everything)

Where possible, learn what the seller values most. For example:

• Do they need a quick settlement?
• Do they need a longer settlement to line up another purchase?
• Are they focused on certainty (unconditional offers), or willing to consider conditions?

Your offer can often be made more attractive by matching the seller’s preferred timing and reducing uncertainty, sometimes without paying more.

Keep in mind: the agent works for the seller, so they’ll aim to achieve the best overall outcome for the vendor. That said, a good agent will still help you understand the process and present your offer fairly.

4. Set your maximum price, and stick to it

Negotiations can become emotional, particularly when you’ve pictured yourself living in the home. Before you submit your offer:

• Decide the maximum you’re prepared to pay.
• Make sure it’s a number you can live with (even if a valuer or a friend disagrees).
• Avoid negotiating past your comfort zone just to “win”.

If the market is moving fast and you need to act decisively, a clear “best and final” offer may be the right call.

5. Get finance organised early

If you haven’t already, talk to your lender or broker about pre-approval. It shows the seller you’re serious and ready to move.

You can still make an offer subject to finance, but understand that:

• It adds uncertainty for the seller.
• The seller may prefer a lower offer with fewer conditions.
• Your finance condition should ideally include a clear timeframe.

6) Always put your offer in writing

Verbal offers don’t count. A private treaty offer should be in writing and signed, with your key terms clearly stated (price, deposit, conditions, settlement date).

It’s also normal to reassess your offer during negotiation, just make sure every change is documented properly.

Conditional vs unconditional offers: what you need to know

Conditional offers

A conditional offer is a binding agreement subject to certain conditions being met. If those conditions aren’t satisfied within the timeframe, you may have the right to withdraw.

Common conditions include:

• finance approval
• property valuation
• building inspection (and other due diligence checks)

Conditions can protect you, but they can also make your offer less appealing if the seller has other choices.

Unconditional offers

An unconditional offer is a firm commitment to buy the property on the stated terms. This is attractive to sellers because it provides certainty.

However, you should only go unconditional when you’re fully confident you can proceed because once accepted, you’re generally committed and may risk your deposit if you can’t complete the purchase.

Before you sign: get legal advice

Whether your offer is conditional or unconditional, it’s wise to speak with a solicitor or conveyancer before signing anything. They can help you understand:

• your legal obligations
• what your conditions actually mean in practice
• any clauses you may need to include for protection

Buying a property can feel high-stakes and private treaty negotiations can move quickly. Preparation (finance, research and clear limits) gives you the best chance of negotiating well, without unnecessary stress.
