Are Zillow Estimates Accurate? Here's What You Need to Know About Zestimates in Douglas County

If you’ve ever looked up your home on Zillow and thought, “Wait, my house is worth what?”—you’re not alone.

As local real estate expert Jeannie Haacke from The Mary Gilbert Group at Keller Williams Southern Oregon puts it, “That’s the million-dollar question, sometimes literally!”

In this post, we’re breaking down what Zillow estimates (aka “Zestimates”) are, why they’re often off base, and what you should do instead if you want to know your home’s true value in places like Roseburg, Green, Sutherlin, or anywhere else in Douglas County.

What Is a Zestimate, Really?

Zillow uses something called an AVM, Automated Valuation Model. It pulls data from public records, previous home sales, and neighborhood trends to generate a rough estimate of your home’s value.

The problem?

It’s not a person.

It doesn’t know if you:

• Just remodeled your kitchen

• Installed a new roof

• Live next to a busy road

• Or if your neighbor’s house with the same floor plan had serious foundation issues

In other words, it’s like trying to price a used car without popping the hood

Real-World Example: Zillow Was $35,000 Off

Here's a recent example from the Green area of Douglas County: We listed a home for $425,000. Zillow estimated it at $390,000. But the home had a brand-new roof, updated bathrooms, and a huge corner lot. It sold for full price in less than a week.

That’s a $35,000 difference, and a reminder that a Zestimate doesn’t always tell the full story.

Why Zestimates Miss the Mark in Southern Oregon

Douglas County isn’t cookie-cutter suburbia. We’ve got everything from riverfront cabins to ranches with acreage to mid-century homes in town. That kind of diversity makes it tough for automated models to give an accurate picture.

Here’s what typically causes Zestimates to be off:

• They don’t reflect recent upgrades or deferred maintenance

• They use "comparable" properties that really aren’t comparable (like mixing townhomes with rural properties)

• They miss location-specific details like school zones, views, lot size, road noise, and more

What Should You Do Instead?

A Zestimate can be a decent starting point, but it should never be treated as the actual market value.

If your estimate feels off—or if you're seriously thinking of buying or selling, your best move is to talk to a local real estate expert.

A professional Comparative Market Analysis (CMA) will:

• Use current, local data from real sales

• Account for your home’s condition and upgrades

• Factor in local nuances that Zillow can’t possibly understand

The way we see it: “Zillow doesn’t live in Roseburg. We do.”

Can You Challenge a Zestimate?

Yes, and in some cases, it can make a difference. Jeannie and her team have helped homeowners contest online valuations by providing real sales comps. This can be helpful when negotiating with lenders, setting insurance values, or simply understanding your true equity.

The Bottom Line

Zillow and other real estate websites are helpful tools, but they’re not a substitute for local expertise. If you're wondering what your home is really worth in Douglas County, don’t ask an algorithm—ask someone who actually lives here.

Whether you're buying, selling, or just curious, The Mary Gilbert Group are here to help you get the facts—and the results—you deserve.
