How Much Is My House Worth? Why a Realtor’s Price Is Different From Zillow

It’s one of the first questions every homeowner asks: “How much is my house worth?”
And it’s usually followed by a quick search on Zillow or another real estate website. Within seconds, you see a number—your “Zestimate.” Sounds easy, right? The problem is, those online values are often off by tens of thousands of dollars.

Here’s why.

Zillow uses data, not eyes.

Zillow’s algorithm pulls from public records, bedrooms, bathrooms, square footage, lot size, and recent nearby sales. What it can’t see are the things that really influence a home’s value:

• Your upgraded kitchen or new roof.

• The mountain view from your backyard.

• That your neighbor’s “comparable” sale was a fixer-upper.

• Or the quiet cul-de-sac that buyers love.

Zillow doesn’t walk through your home. It can’t smell fresh paint, feel the light, or understand curb appeal. It’s using averages, not details and real estate value is all about details.

A Realtor uses market experience, not math alone.

When I prepare a Comparative Market Analysis (CMA) for a client, I don’t just plug in numbers. I analyze what’s really happening in the local market—buyer demand, current inventory, interest rates, and recent upgrades that matter to buyers today.

I also preview homes in your neighborhood, talk with appraisers, and look at what sold, what didn’t, and why. That’s how I find your home’s true market value—the price that gets attention and offers, not just views online.

Zillow gives a guess. A Realtor gives a strategy.

The online estimate is just a starting point. A Realtor’s price isn’t about guessing—it’s about positioning your home to sell for top dollar in today’s conditions. That includes marketing, timing, and understanding buyer psychology—something no algorithm can do.

Bottom line

Zillow can be helpful for curiosity, but if you’re serious about selling—or even refinancing—you need a professional opinion.

Your home’s value isn’t determined by a computer. It’s determined by the market—and how well your Realtor understands it.
