How Estate Agents Value Property
How Estate Agents Value Property
Understanding how estate agents arrive at a valuation helps you evaluate the figures you are given and make a more informed decision about your asking price. This guide explains the methods agents use — and the incentives that can distort them.
The Comparable Method
The primary method estate agents use to value residential property is the comparable method — looking at what similar properties in the same area have recently sold for. This is the most objective approach and the one most closely aligned with what the market will actually pay.
- Agents look for properties similar in type, size, condition and location
- They focus on sold prices, not asking prices — sold prices reflect what buyers actually paid
- Recent comparables (within the last three to six months) are weighted more heavily
- Adjustments are made for differences — a comparable with an extra bedroom or larger garden will have sold for more
- The Land Registry, Rightmove and Zoopla all publish sold price data that agents use
- You can access the same data yourself to sense-check any valuation you receive
Local Knowledge and Market Conditions
Beyond comparable evidence, experienced agents bring local knowledge that data alone cannot capture. They know which streets are more desirable, which schools are oversubscribed, and how current market conditions are affecting buyer behaviour in your specific area.
- Local agents know which micro-locations command a premium within a postcode
- They understand current demand — how many buyers are actively looking for your type of property
- They know how long similar properties are currently taking to sell
- They can assess whether the market is moving up, down or sideways
- This contextual knowledge is genuinely valuable — it is one reason to use a local agent
The Incentive Problem: Buying the Instruction
Estate agents are paid on commission — they only earn money if they sell your property. This creates an incentive to win your instruction, which can lead some agents to inflate their valuations. This practice is known as "buying the instruction".
- An agent who values your property highest is most likely to win your instruction
- Some agents deliberately overvalue to secure the instruction, planning to manage a price reduction later
- This is a well-known problem in the industry — sellers should be aware of it
- An inflated valuation is not in your interest — it leads to a slow sale and often a lower final price
- The agent who values highest is not necessarily the best agent to instruct
How to Sense-Check a Valuation
You do not have to take an agent's valuation at face value. With publicly available data and a little research, you can form your own view of what your property is worth and use that to evaluate the figures you are given.
- Look up sold prices for similar properties in your street and surrounding streets on Rightmove or Zoopla
- Focus on properties sold in the last three to six months
- Adjust for obvious differences in size, condition and features
- If an agent's valuation is significantly higher than your own research suggests, ask them to justify it with specific comparables
- Get valuations from at least two or three agents and compare their reasoning, not just their figures
- Be wary of an agent who cannot or will not show you the comparables behind their valuation
What to Ask at a Valuation Appointment
A valuation appointment is not just about the number — it is also an opportunity to assess the agent and their approach. Asking the right questions helps you get more from the appointment.
- What comparable properties have you used to arrive at this figure?
- What do you think the property will actually sell for, as opposed to what you would market it at?
- How long are similar properties currently taking to sell in this area?
- What would you recommend if the property hasn't sold after four weeks?
- How many properties have you sold in this street or postcode in the last six months?
- What is your fee, and what does it include?
