What Is My Home Worth?
Why That Online Estimate Might Be Off by Tens of Thousands of Dollars
"What is my home worth?" is one of the most searched real estate questions there is, and it makes sense why. Whether you are thinking about selling this year or just keeping an eye on your equity, you want a real number. The problem is, the fastest answer, typing your address into Zillow, is often not the most accurate one. Here is what you actually need to know.
Why Online Estimates Are Not the Full Picture
Zillow publishes its own accuracy numbers, and they are worth understanding. For homes that are actively listed for sale, the median error is between 1.74 and 2.4 percent, which is fairly close. But for homes that are not currently listed, which is most homeowners just checking their value, the median error jumps to between 7.06 and 7.49 percent.
On a $500,000 home, a 7.49 percent error works out to about $37,450. On a $750,000 home, that is over $56,000. And remember, that is the median error, meaning half of all online estimates are off by even more than that.
Why does this happen? Online tools cannot walk through your home. They do not know that you updated your kitchen, added a new roof, or finished your basement unless that information happens to be in public records. They also cannot account for how buyers are actually behaving in your specific neighborhood right now.
What Actually Determines Your Home's Value
A real Comparative Market Analysis, often called a CMA, looks at actual closed sales from the past 90 to 180 days for homes that are genuinely similar to yours in size, condition, age, and location. It also factors in things no algorithm can see: the quality of your renovations, how your home compares to what is currently competing against it, and how quickly homes are moving in your specific area right now.
This is also why two homes on the same street can have very different values. A home with an updated kitchen and new HVAC is not the same as its neighbor with original 1990s finishes, even if the square footage is identical. Online tools tend to blur these differences together.
What This Means If You Are in Central North Carolina
In markets like Burlington, Gibsonville, and Greensboro, & surrounding areas home styles and lot sizes vary a lot street by street, which makes broad online estimates even less reliable. A 4 bedroom home on a quarter acre lot in a subdivision is priced very differently than a similar sized home on several acres. A proper CMA accounts for that. An algorithm often does not.
What This Means If You Are Along the Grand Strand or NC Coastal Beaches
Coastal and golf course communities are exactly the kind of market where online estimates struggle most. View lots, water access, proximity to the beach, and community amenities can shift a home's value significantly, and these are details that automated tools frequently miss or underweight. If you own property in along the Waterway, Beach, or anywhere near the coast, a local CMA is going to reflect your home's real value far better than a generic online number.
Quick Takeaway
Online estimates for homes not currently listed can be off by 7 percent or more
On a $500,000 home, that is a potential $37,000+ swing
A CMA uses real, recent, local sales data plus a firsthand look at your home
Bottom line: use online estimates as a starting point, never as your final number.
