How Reliable Are Home Valuation Tools?

It seems like a simple question, but finding that answer is more complicated than it might seem. Sites like Zillow, Redfin, Eppraisal, and others have built-in home valuation tools that make it seem easy, but how accurate are they? And which one do you believe if you get three different answers? Online valuation tools have become a key part of the home buying and selling process, but they’ve been proven to be highly unreliable in certain instances. One thing that is for certain is that these valuation tools have reinforced that real estate agents are as vital to the process of pricing a home as they ever were – and maybe even more so now.

There are limitations to every online valuation tool. Most are readily acknowledged by their providers, such as Zillow’s “Zestimate”, which clearly states that it offers a median error rate of 5%, with varying accuracy across the country. That may not sound like a lot, but keep in mind that amounts to a difference of about $35,000 for a $700,000 home. For Redfin and Trulia, there are similar ranges in results. When you dig deeper into these valuation tools, it’s no small wonder that there are discrepancies, as they rely on a range of different sources for information, some more reliable than others.

Redfin’s tool pulls information directly from multiple listing services (MLSs) all over the country. Others negotiate limited data sharing deals with those same services, but also rely on public records, as well as homeowners’ records. This can lead to gaps in coverage. These tools can serve as helpful pieces of the puzzle when buying or selling a home, but the acknowledged error rate is a reminder of the dangers of relying too heavily on them.

Home valuation tools can be a useful starting point in the real estate process, but nothing compares to the level of detail and knowledge a professional real estate agent offers when pricing a home. An algorithm can’t possibly know about a home’s unique characteristics or those of the surrounding neighborhood. They also can’t answer your questions about what improvements you can make to get top dollar or how buyer behaviors are shaping the market. All of this – and more – can only be delivered by a trusted professional whose number one priority is getting you the best price in a time frame that meets your needs.
