Are Zillow Zestimates Accurate? What Indiana Homeowners Should Know

If you’ve ever looked up your home on Zillow, you’ve likely seen the Zestimate — Zillow’s automated estimate of your property’s value. But how accurate is it really for homes in Carmel, Indianapolis, and Central Indiana?

A Zestimate is Zillow’s algorithm-based calculation of a home’s market value. It uses public data such as tax assessments, county property records, and comparable sales. However, Zillow does not visit homes in person. That means upgrades, remodels, or unique features might not be reflected in your Zestimate unless you update them manually.

According to Zillow, the nationwide median error rate is about:

 

• 1.8% for homes currently listed on the market
• 7% for off-market homes
  
  

That may not sound like much — but for a $500,000 property, that’s a difference of $35,000 or more.

In fast-moving markets like Central Indiana, home values can shift quickly based on neighborhood trends, school districts, or buyer demand. Zillow’s algorithms can’t always keep up with those hyperlocal factors.

That’s where an experienced Indianapolis Realtor makes all the difference. Realtors analyze neighborhood data, property condition, and market timing — the things that algorithms can’t.

• Claim your home on Zillow to verify and update property details.
• Add accurate information about square footage, upgrades, and renovations.
• Update photos to reflect improvements.
• Make sure your local tax records are current.
  
  

Zestimates are a great starting point — but not a finish line. For the most accurate valuation, consult a Central Indiana real estate expert who knows your neighborhood.
