Certified Property Valuation Guide

Written by: Sydney Property Valuation Editorial

Last updated: June 2026

Introduction

This guide explains what a certified property valuation is, when one is required, and how it differs from a real estate agent’s appraisal or an online estimate. It is written for anyone who has been asked to obtain a "proper" or "independent" valuation and wants to understand what that means and what to expect.

A certified valuation is a formal, independent assessment of a property’s value prepared by a qualified valuer and set out in a written report. Unlike a quick estimate, it is evidence — the kind relied on for legal, tax, financial and compliance purposes.

This is general information only and is not legal, financial or tax advice. For a specific matter, obtain advice from a qualified professional.

Who this guide is for

Property owners and buyers who need an independent value
Solicitors, accountants and advisers who instruct valuations for clients
Anyone unsure of the difference between a valuation, an appraisal and an estimate

What "certified" means

In Australia, formal property valuations are prepared by qualified valuers — commonly a Certified Practising Valuer (CPV), a designation held by members of the Australian Property Institute who meet its qualification and experience standards. A certified valuer is independent of the sale and prepares the report to professional standards, which is what gives the figure weight for formal purposes.

A certified valuation report generally includes:

A description of the property and the interest valued
The purpose and effective date of the valuation
The basis of value (usually market value)
The evidence relied on, including comparable sales
The valuer’s reasoning and assumptions
The valuer’s qualifications and signature

Valuation vs appraisal vs estimate

These terms are often used loosely, but they are not the same:

Certified valuation: An independent, evidence-based assessment prepared by a qualified valuer in a formal report. Suitable for legal, tax and financial purposes.
Real estate appraisal: A selling agent’s opinion of likely sale price, usually free and provided to win a listing. Useful for pricing a sale, but not independent evidence.
Online estimate: An automated figure based on data models. A rough guide only, with no inspection and no professional judgement.

For most formal purposes, only a certified valuation will be accepted.

When a certified valuation is required

A certified valuation is commonly needed for:

Capital gains tax and other tax matters
SMSF compliance and audit evidence
Deceased estates and probate
Family law property settlements
Litigation and expert evidence
Related-party transfers and stamp duty evidence
Financial reporting and accounting
Insurance (replacement cost) purposes

Whether one is legally required depends on the situation, so check with the relevant professional — a solicitor, accountant or auditor — about what your matter needs.

What to expect from the process

A typical certified valuation involves the following stages:

Instruction: You confirm the purpose, the property and the required date.
Inspection: The valuer inspects the property (internally and externally where possible) and notes its condition, size and features.
Research: The valuer analyses comparable sales and relevant market evidence.
Analysis: The valuer applies the appropriate approach and forms an opinion of value.
Reporting: You receive a written report setting out the value and the reasoning.

Timeframes vary with the property type, access and complexity. Retrospective valuations (for a past date) usually take longer because historical evidence must be researched.

Common mistakes to avoid

Relying on an appraisal where a valuation is required: An appraisal is not independent evidence.
Not stating the purpose: The purpose shapes the basis and date of value.
Assuming one report suits every purpose: A valuation for a mortgage is not automatically right for tax or family law.
Choosing on price alone: For formal matters, the valuer’s qualifications and the report’s defensibility matter more than a cheap fee.
Leaving it too late: Deadlines for legal and tax matters can be tight; instruct early.

Frequently asked questions

What makes a valuation "certified"? It is prepared by a qualified valuer — commonly a Certified Practising Valuer (CPV) — to professional standards, independent of the sale, and set out in a formal report. That independence and rigour is what gives it standing for formal purposes.
Is a bank valuation a certified valuation? A lender’s valuation is prepared by a qualified valuer, but for the lender’s security purposes. For your own formal needs — tax, legal, estate or compliance — you generally commission a separate independent certified valuation.
How is it different from an agent’s appraisal? An appraisal is a selling agent’s opinion of likely sale price, usually free and aimed at winning a listing. It is not independent evidence and is not accepted for most formal purposes.
How long does a certified valuation take? It varies with property type, access and complexity. Retrospective valuations take longer because historical market evidence has to be researched.
Can I use one certified valuation for several purposes? Not always. The basis and date depend on the purpose, so a report prepared for one purpose may not suit another. Tell the valuer every intended use up front.
Does a certified valuation guarantee a sale price? No. It is an independent assessment of value on a defined basis and date, not a prediction of what a particular buyer will pay on a given day.

Professional use note
