Can You Trust Auto Valuations?

Jamie Harrington Posted on 30 July 2025

It’s a question we get asked all the time: “I looked up my property on an online tool—how accurate is the valuation?”

The truth? Auto valuations can be a helpful starting point, but they’re rarely spot-on—and sometimes, they’re wildly off the mark.

What Are Auto Valuations?

Auto valuations are generated by algorithms using recent sales data, market trends, and property records. You enter an address, and it instantly provides an estimate or a price range. On our own website, for example, you can now access this tool. The result is colour-coded—green, orange, or red—to indicate the estimated accuracy.

Green means “go”—you should be able to rely on it.

But in reality? We’ve seen plenty of green-rated valuations that miss the mark by a long shot.

What They Get Right

To be fair, these tools can provide useful insights:

  • Recent comparable sales
  • Market trends in your area
  • General price ranges

They’re quick, easy, and a great way to start thinking about your property’s value.

What They Miss

There are many crucial factors an algorithm simply can’t account for, such as:

  • A premium view or orientation
  • A home on a busy road
  • High-end renovations or extensions
  • The overall presentation and feel of the property
  • Unique features that don’t exist in recent sales

These are the elements that buyers notice—and they significantly affect price.

The Bottom Line

If you’re just curious or want a ballpark idea, an online valuation tool is a good place to start. But if you're serious about selling, refinancing, or simply want to understand your property’s true market position, your best next step is to speak with a local real estate professional who knows the area—and your property—inside out.
