Formal appraisal & value

Do you know the real reason behind online home value checks?

12 December 2025 · 3 min read

These days it seems like a national pastime: calculating your home's value online. Open a tool, enter your postcode and house number, and within seconds a figure appears that lets you dream of a sunny future. It is quick and simple. But behind that smoothly presented false certainty lies something that has little to do with the reality of the housing market.

The illusion of averages

We love figures and averages; they give us a sense of control. But blindly trusting an online valuation is like getting a medical diagnosis from a search engine: sometimes it comes close, but often it is mainly misleading. An algorithm does not know your house. It has never felt the warmth of an extension or seen the shadows that fall across the garden in the afternoon. It lacks the finesse that our estate agents build up through years of daily work in the local market.

The disappointment that follows

We see the same thing happen time and again: people call with an online valuation report that puts their home thousands of euros higher than reality. As soon as we step inside, we often see straight away that this dream value is not right. Sometimes the real value is lower, sometimes much lower, but it never matches the digital estimate exactly. That moment is painful for the owner, and it costs you a lot of time to find out who has actually given the right value.

The commercial circus

What often follows is a mini circus of estate agents who come round to tell you otherwise. Not because they have better information, but because they want to win the assignment. One promises the earth, another builds castles in the air, and before you know it you are lost in a fog of conflicting stories. In the end, people usually choose the agent who was best at telling them what they wanted to hear.

Where real value begins

A real valuation does not start with figures, but with an estate agent who steps into your home. A system only sees what has been registered at some point, but an experienced estate agent reads a house: the years of maintenance you have put into it, the way the light falls through the living room, how logically the rooms flow into each other. Details that no algorithm can understand.
