Understanding Free Property Valuations by Estate Agents: The Limitations and a Better Solution

A free valuation from an estate agent is a useful starting point, but it is not an independent valuation — and treating it as one is how sellers under-price and buyers over-pay. Here is what a free appraisal is for, where it falls short, and what to use when the number matters.

What a free agent appraisal really is

An agent’s free valuation is a market appraisal aimed at winning the mandate to sell. It is informed by local experience, but the agent has an interest in the outcome — a price that secures the listing is not always the same as the price the data supports.

Where it falls short

Free appraisals rarely show their working: which comparable sales were used, what the property last sold for, or how condition was weighted. Without the underlying Deeds Office sale data, the figure is hard to challenge or defend — a problem for estate executors and divorcing couples in particular.

The better solution

For decisions where the number has consequences, use a data-driven Property Valuation Report that combines municipal valuations, actual comparable sales from the Deeds Office, and statistical modelling into a transparent low-to-high range. For bond approval you still need a sworn valuation by a registered valuer.

Read the data yourself
