Why Owner Estimates and Market Value So Rarely Align
There is a well-documented pattern in residential property sales where the price a homeowner believes their property is worth sits consistently higher than what the market produces. This is not a character flaw. It reflects the simple reality that the people who live in a home see it differently from the people who might buy it. A buyer walking through for the first time sees the property without the history. They compare it against everything else available at the same price point. They discount for things the owner has stopped noticing.
The number that matters in a property sale is not what the owner needs, not what the agent suggests at the listing appointment, and not what an online tool calculates from postcode-level data. It is the number a qualified, motivated buyer will commit to after inspecting the property, reviewing comparable sales, and making a decision based on current market conditions.
This distinction matters before any other decision is made.
How Much Is My House Worth - The Three Methods Used to Work It Out
Professionals determining what a property is worth typically rely on a combination of three approaches, each suited to different property types and market conditions.
The most commonly applied method in residential real estate is the comparable sales method - sometimes called the direct comparison approach. This involves identifying properties that have recently sold in the same area with similar characteristics: land size, bedroom count, construction era, condition, and street position. The sale prices of those comparable properties establish a reference range within which the subject property is then positioned.
The second method is the capitalisation of income approach, which is used primarily for investment properties. It converts the expected rental income of a property into a capital value using a market-derived yield rate. This method is less relevant for owner-occupied homes but becomes important when a property has an established rental history or is being assessed for investment purposes.
The third method is the summation or cost approach. This adds the estimated land value to the depreciated cost of reproducing the improvements on that land. It is most useful for unique properties where comparable sales are limited or for new constructions where the cost of building is a reliable value indicator.
A well-constructed residential appraisal typically leads with comparable sales analysis and uses the other methods to test whether the result sits within a reasonable range.

The Problem With Online House Price Calculators
Online property estimate tools are widely used and widely misunderstood. They provide a useful starting point for market awareness but a poor foundation for pricing decisions.
The algorithm sees postcode-level patterns. It does not see that the kitchen was renovated twelve months ago, that the block has a north-facing rear yard, or that the neighbouring property creates a noise issue that every prospective buyer notices during inspection.
Automated estimates serve a purpose at the research stage. They tell you roughly what the market in a given area looks like. They cannot tell you what your specific property will achieve on a specific day in current conditions.
The gap between the estimate and the result is where sellers get into trouble.
Why a Property Appraisal From a Local Agent Outperforms Any Online Tool
What separates a professional appraisal from an online estimate is not just data access. It is the local context, the current buyer intelligence, and the capacity to assess individual property attributes that do not appear in any dataset.
A local agent conducting a thorough appraisal draws on three sources of knowledge simultaneously - the documented sales record, the current buyer pool, and the accumulated experience of operating in that specific market. Each of those inputs shapes the appraisal in ways that a statistical model cannot replicate.
The output of a well-conducted appraisal is a defensible price position, not an estimate. It gives the vendor a clear understanding of where their property sits in the current market, what is driving that assessment, and what a realistic buyer pool looks like at that price level.
Frequently Asked Questions - How Much Is My House Worth
How much time does a property appraisal take
A standard residential property appraisal typically involves a walkthrough of the property lasting between 20 and 45 minutes, followed by the agent conducting comparable sales research to support their assessment. The full process from inspection to receiving a written appraisal usually takes between 24 and 72 hours depending on the agency and the complexity of the property.
What separates an agent appraisal from a paid valuation
A property appraisal provided by a real estate agent is typically offered at no cost to the homeowner. The agent provides the appraisal as part of establishing a relationship with a potential vendor. This is distinct from a statutory valuation conducted by a certified practising valuer, which is a fee-for-service assessment used for legal, financial, or insurance purposes.
When should I get a new property appraisal
Property markets move and an appraisal reflects conditions at the time it was conducted. In an active market, an appraisal prepared more than three to six months ago may no longer accurately reflect current value. Vendors preparing to sell should request a fresh appraisal within 60 to 90 days of their intended listing date to ensure their price position is based on current comparable sales.
Does presentation affect the appraisal result
Presentation does influence an appraisal, though its impact is more nuanced than many vendors expect. An agent conducting a thorough appraisal is assessing the property against market comparables, so presentation that brings the home to a standard consistent with comparable sales is worthwhile. Presentation that exceeds the area standard is unlikely to produce a proportional increase in the appraisal figure.
