Council Valuation vs Market Value: What the CV Actually Tells You

Almost every homeowner in Auckland knows their CV. Far fewer know what it is actually for, and the gap between the two numbers causes a lot of confusion at the point of sale.

What a council valuation is

A council valuation — the CV, sometimes called the RV or rating valuation — exists for one purpose: to divide the rates bill fairly between properties. Auckland Council revalues every property in the region on a three-yearly cycle, and it does so as a mass appraisal exercise. Nobody visits your house.

The valuation is built from what the council knows on paper: land area, floor area, the number of bedrooms and bathrooms on record, the zoning, and what comparable properties in the area sold for around the valuation date. It is split into land value and improvement value, which together make the capital value.

Why it differs from market value

Several reasons, and they compound.

• It is out of date the moment it is published. The valuation reflects a specific date, and by the time you see it the market has moved. In a fast-moving market the gap widens quickly.
• Nobody inspected the property. A renovated kitchen, a new roof, a rotting deck and a leaking shower all look identical to a mass appraisal model. So do a beautifully presented home and a tired one.
• It cannot see the things buyers pay for. Aspect, outlook, noise from a nearby arterial, whether the sun reaches the living room in winter. These move prices materially and none of them are on the council record.
• It does not price development potential well. Two identical houses on identically sized sites can be worth very different amounts if one can take additional dwellings under the Unitary Plan and the other cannot.

So which number should you use?

For rates, the CV. For anything else, market value.

If you are deciding whether to sell, refinancing, working out your equity, or setting expectations with family, the CV is at best a starting point. Buyers do not bid based on it. Agents do not price to it. Banks lend against a registered valuation or their own model, not the CV.

The one place it still carries weight is negotiation, because buyers often quote it. Knowing whether your property should trade above or below its CV — and being able to say why — is genuinely useful when an offer comes in low with "but the CV is only…" attached to it.

Getting the number that matters

A market appraisal from a licensed agent who sells in your suburb is free, takes about fifteen minutes on site, and is based on what comparable properties have actually sold for recently. That is the number that tells you what your home is worth today.
