Ask sellers why they hired an agent and pricing usually tops the list. It feels like the expert part, the bit where you need someone who “knows the market”. So let’s say the useful thing out loud: an agency appraisal is a comparable-sales analysis, the data behind it is public, and if “how to price my house” is the question sitting in your search history, you can build the same analysis yourself, in NZ, in an afternoon.
The short version: set the CV aside, gather five to ten settled sales of similar homes near yours from the past three to six months, and adjust for the differences you can see. Cross-check the resulting range against the estimate sites, pay for a registered valuation if you want an independent professional number, and price near the evidence at launch: the NZ data shows listings that start too high go cold.
Why your CV isn’t your price
Your CV is a rating valuation, produced in bulk for your council to divide rates between properties. It can be years old by the time you sell, and nobody inspected your home to produce it (settled.govt.nz). We’ve written a whole post on what the CV is actually for; when you’re pricing, treat it as one dated data point, never the anchor.
How do I price my house without an appraisal?
You build what the industry calls a comparable-sales analysis. Five steps.
-
Work from settled sales, not asking prices. An asking price is a hope with photography; a settled price is what a buyer’s money did. homes.co.nz, OneRoof and QV all show sold prices once sales settle, free.
-
Stay recent. Three to six months is the window; older sales describe a market that no longer exists. If your suburb has been quiet, widen the area to similar neighbouring streets before you widen the time window.
-
Compare like with like. Similar land, bedrooms, era and condition, as close to home as you can get. Five to ten sales is plenty, and three close matches beat ten loose ones.
-
Adjust honestly, in writing. The renovated bathroom nudges you up the range; the main road or the shaded section nudges you down. Writing each adjustment down before you look at the total is the discipline that keeps hope out of the spreadsheet.
-
Land on a range, and know why it has edges. The comparables give you a corridor. Where you sit inside it depends on presentation, timing and how many similar homes are for sale the week you list.
That’s the method, and it’s the same one behind a good agency appraisal; settled.govt.nz’s guidance on working out what your property might be worth points to the same inputs. The difference is that when you build it yourself, you understand every number in it, which pays off the day you’re sitting across the table from a buyer.
What the estimate sites can and can’t tell you
homes.co.nz, OneRoof and QV publish automated estimates alongside their sales data, generated from council valuations and recent sales. They’re useful for reading direction and for building your comparables list. They’re weaker as a verdict on your specific home: nobody has seen inside it, and the same address returns different numbers on different sites. Quashed compared the main property-information sites, and the spread between their estimates makes that point better than we can. Use them to sanity-check your range, and when an estimate and your comparables disagree, trust the work you can explain.
When a registered valuation is worth paying for
A registered valuer is an independent professional who inspects your home in person and gives you a written market valuation, with no stake in flattering you. It’s also the kind of document banks treat as evidence when a buyer’s lending needs certainty, so it carries weight on the other side of the deal too. It earns its fee when your home has few good comparables, when co-owners can’t agree on a number, or when you want a figure in the drawer that nobody can accuse of wishful thinking. An agency appraisal, remember, is free precisely because it’s marketing.
The mistake that sinks private sales
Anchoring high and chasing the market down. It’s the failure mode agents warn about, and on this one they’re right. In RNZ’s July 2025 report on the Cotality data, one salesperson observed that a private seller naming a too-high price can “kill the deal”, and the pattern described is consistent: sellers who launch high, then cut, then cut again, follow the market down while the listing “goes cold”. Buyers can see days-on-market, and a listing that’s been sitting for months gets asked different questions. Pricing near the evidence at launch is the single biggest lever a private seller controls. It’s also the entire reason to do the comparable work before the photographer shows up rather than after the third quiet open home.
Reserve, happy, dream
Once you have your range, hold it as three numbers. Your reserve is the floor: below this, you don’t sell. Your happy number is where the deal feels properly done. Your dream number is what happens if two motivated buyers arrive the same weekend. Set all three before the first open home, while you’re calm, because their whole value is that they were made calmly. When an offer lands at 8pm on a Tuesday, you’re comparing it against decisions you already made, instead of improvising with your heart rate up.
And to be clear about whose numbers these are: yours. They come out of your comparable work, and nobody should hand them to you, including us. Celby’s tools and videos teach exactly this method, and we stop where the method stops. We’ll show you how the research works. The price is yours to set.
