The Truth About Zillow Estimates: What You Need to Know...
If you’ve ever searched for your home online, chances are you’ve checked your Zillow Zestimate—maybe even more than once. It’s tempting: one click, and you get a home value estimate instantly. But how accurate is it, really? And should you rely on it when buying or selling a home?
Here’s the truth about Zillow estimates—and why they should be a starting point, not the final word.

What Is a Zestimate, Anyway?
Zillow’s Zestimate is an automated valuation model (AVM) that uses public data, recent sales, tax records, and MLS feeds (when available) to estimate a home’s value. It’s powered by algorithms—not by humans—and it’s updated frequently based on the data it pulls in.
While it can provide a rough ballpark figure, it’s important to know it doesn’t take everything into account.

What Zillow Can’t See
Zillow doesn’t walk through your house—and that’s where accuracy starts to fall apart. It doesn’t know:
· If you just remodeled your kitchen or bathrooms
· Whether your home has high-end finishes or builder-grade features
· How your home compares to others in the neighborhood
· If you’ve added a new roof, central air, or a finished basement
· What the actual condition is (pristine vs. worn)
It also can’t factor in things like:
· Lot desirability (corner lot, quiet street, water views)
· Unique layouts, additions, or unpermitted work
· Local buyer demand or seasonal market shifts

How Accurate Is the Zestimate?
Zillow publishes its own accuracy data, and even they admit there’s room for error. In some markets, Zestimates can be off by 5–10% or more. On a $600,000 home, that could mean a difference of $30,000 to $60,000—which is huge when you’re buying or selling.
Accuracy can vary dramatically based on location and how much local data Zillow has access to. In dense urban areas, they may be closer to the mark. In rural or fast-moving markets? Not so much.

When a Zestimate Can Be Useful
Zestimates are helpful for:
· Getting a general idea of home values in your area
· Watching long-term trends in your neighborhood
· Starting a conversation about your home’s worth
Just don’t treat it as an appraisal—or the price you’ll actually get when you sell.

The Best Way to Know What Your Home Is Worth
If you’re thinking of selling (or just curious), the best way to get a true market value is to speak with a local real estate expert—someone who:
· Knows your neighborhood inside and out
· Can compare your home to recent local sales
· Understands what today’s buyers are looking for
· Evaluates your home’s unique features and upgrades
That’s something no algorithm can do.

Final Thoughts
Zillow is a great tool for browsing homes and getting general info—but when it comes to pricing your home, accuracy matters. Don’t leave money on the table (or overprice and sit on the market) based on a guess.
