Negotiating when the buyer knows you saved the commission

There’s a conversation most private sellers have eventually. A buyer walks through, likes the place, and then mentions that there’s no agency on the listing, so surely there’s room in the price. The dynamic is documented: when RNZ examined private selling in July 2025, a Wellington salesperson observed that some buyers expect to pay less in a private sale because the seller isn’t covering a commission.

So if you’re negotiating a house sale privately in NZ, you want an answer ready for that moment. Happily, the arithmetic is on your side, and so is the evidence.

Some buyers will open low in a private sale because they know there’s no commission in the deal. On the July 2026 national median of $760,000, the commission a private seller isn’t paying comes to roughly $26,450 at published big-agency rates, so even a seller who shares part of that saving finishes well ahead of the agented alternative. The discount the buyer wants is room you actually have.

The lowball is rational, so treat it that way

An opening number is information about what the buyer hopes, and nothing more. From their side, trying for a share of your commission saving is sensible; you’d do the same. Getting offended wastes the one advantage a private seller holds in that exact moment, which is that nobody is pressuring you to respond before you’ve thought.

It also helps to remember what settled.govt.nz, the Real Estate Authority’s consumer site, says about private sales: you “may have more control of the sale and negotiation process” because you’re dealing directly with buyers, and you know your own property best. The person who has lived with the house’s sun, storage and street noise knows more about what’s being sold than any third party ever will.

The maths of negotiating a house sale privately in NZ

Start with the number everyone’s circling. On the July 2026 REINZ national median of $760,000, commission at Barfoot & Thompson’s published rates (3.95% on the first $400,000, then 2%, plus GST) comes to roughly $26,450. Most agencies also charge a marketing campaign of $2,000 to $5,000 on top (2026 cost-of-selling guide). Call it $28,500 to $31,500 to sell the median home through an agency.

Now run the negotiation the buyer wants. Say they ask for $20,000 off “because there’s no agent”, you counter, and you land $10,000 under your asking price. Compare that with selling through an agency at your full ask: you’d collect $10,000 more at the top line and hand nearly $26,500 of it straight back in commission, before the marketing bill. Meeting a buyer partway with money that was never going to reach your account still leaves you five figures ahead, and it leaves the buyer ahead too. The only party worse off in that trade is the agency that wasn’t in the room.

That’s the reframe to settle on before your first open home: the commission you’re not paying is negotiating room. You can hold all of it, or share some of it, and either way you bank more than the agented version of the same sale.

Your number needs evidence behind it

The commission-discount gambit works best against a seller whose price is a hope. It works worst against a seller whose price is a spreadsheet.

Before you list, build your price from comparable settled sales: what similar homes nearby actually sold for in recent months, rather than what their owners are asking. settled.govt.nz’s pricing guidance is blunt that a council valuation is a rating tool rather than a market price, and points sellers to recent sales data, the portals’ estimates and, if you want the gold-plated version, a registered valuation. When your ask rests on three settled sales within walking distance, “you saved the commission so drop the price” stops being an argument about the house and becomes an argument about who keeps the saving. You can answer it with sold prices instead of adjectives.

The agent-side warning in that same RNZ piece deserves airtime here, because it’s fair: private sellers who start too high tend to follow the market downhill, cutting the price after the audience has moved on. Pricing from evidence at launch protects you from the lowball, and from yourself.

Counter-offers, silence, and your reserve

The mechanics are simpler than the nerves. Under settled.govt.nz’s counter-offer guidance, you respond to a written offer by changing the terms (price, settlement date, chattels, conditions) and sending it back through the lawyers. A counter takes the buyer’s original offer off the table, so send numbers you’d be content to see signed. Nothing binds until both parties have signed the same version. Most offers will be conditional ones, and we’ve covered how conditions work in a separate guide.

Three habits do most of the work from there.

Know your reserve before the first viewing. Decide, in a calm hour with the comparable sales in front of you, the number below which you’ll keep the house, and write it down. Every later decision gets easier once that number exists.

Let silence do some lifting. You don’t have to reply the evening an offer arrives. A considered reply beats a rattled one, and most written offers give you time to think (check any expiry with your lawyer). Buyers read composure as confidence in the price, because that’s what it is.

And know when to walk. If an offer stays under your written reserve and under what the settled sales support, declining is a complete answer. The first buyer through the door won’t be the last.

One more reassurance, since “you’ll be out-negotiated” is the fear underneath all of this. The two best like-for-like studies anyone has run, at Stanford and in Madison, Wisconsin, found that homes sold through professional agents fetched no higher prices than owner-sold homes; they sold faster, and that was the whole difference. You’re not surrendering a superpower by sitting across the table yourself.

Where Celby fits, and where it deliberately doesn’t

Celby never negotiates for you. Enquiries and offers land in your hands and nobody else’s, because you’re the seller and the decisions are yours. What our $8,000 flat fee covers is the ground under your feet: professional photography, the Trade Me listing, a conveyancing lawyer for every counter and condition, and plain guidance on how the pricing research works, so the number you defend has evidence behind it.

You don’t need a harder edge than the buyer. You need a better-prepared one.

Celby is not a licensed real estate agent. You’re selling your property privately, and all decisions about your sale are your own.
