Is Zillow's Home Value Estimator Accurate? The Truth Revealed! (1)

Zillow accuracy rate | How does it work? | Pros and cons | Zestimate vs. CMA | How it compares

Zillow’s automated valuation model (AVM) provides users with a home’s fair market value based on public and user-submitted data. The company publishes Zestimates for more than 100 million homes nationwide.

Its website claims it uses state-of-the-art statistical and machine learning models to examine hundreds of data points for each home. But is Zillow accurate?

While its off-market home value estimates carry a relatively low median error rate of 6.9%, we found many of its estimates to be inaccurate or outdated.

A licensed realtor can provide you with the most accurate valuation. A real estate agent evaluates your home, values its upgrades and renovations, and compares it to the most recent sales in the area.

However, Zillow and other home value estimators are still useful for a quick ballpark home value estimate, especially if you’re not ready to meet with an agent. Get a free, instant home value estimate now!

Zillow Home Value Estimator

  • Fast, free, and easy to use
  • Low median error rates
  • Useful homeowner dashboard

Zillow’s home value estimator provides users with a “Zestimate” within seconds. It’s one the most accurate home value estimators on the market, with a median error rate of 6.9% for off-market properties.

Its tool is fast and easy to use for a ballpark home value estimate. Homeowners can claim a home and edit its information – such as its beds, baths, and square footage – which may impact its home value.

While Zillow’s home value tool is useful, we found its estimates to be mostly inaccurate, as it often factors inoutdated or irrelevant comparable sales. Users need to claim their home on Zillow, update its key information, and choose new comps for a more accurate home value.

  • Fast, free, and easy to use for a quick home value estimate
  • Accurate compared to peers
  • Useful homeowner dashboard
  • Home values are updated frequently
  • Listing data is often inaccurate or missing
  • Home renovations not considered in Zestimates
  • Often uses irrelevant or outdated comps

  • Homeowners who want a quick ballpark home value estimate and don’t mind updating their home’s key information on Zillow
  • Home buyers who are interested in an active listing and want a quick estimate to see if the home is fairly priced

Median error rate

Home typeError rate

Zillow says it has a national median error rate of 1.9% for active listings and 6.9% for off-market homes, making it the most accurate home value estimator.

That means its Zestimates for half of all off-market homes are within 6.9% of their selling price, and half are not. So your home value estimate could be off by tens of thousands of dollars.

Zillow’s accuracy also depends on your local housing market. Its Zestimates are far less accurate in states and cities with fewer home sales and active listings.

For example, Zillow’s error rate for off-market homes is just 5.3% in Virginia. But its error rates are much higher in states with fewer available Zestimates.

Ultimately, Zestimates are more accurate in markets where Zillow has access to more home sales data.

Like other home value estimators, Zillow’s error rate (1.9%) is much lower on active listings. New listing data – such as square footage, bedrooms, and bathrooms – might have been inputted or updated by a real estate agent, and incorporated into the Zestimate algorithm.

Home value accuracy tool

Our tool breaks down the Zestimate accuracy. It provides a range of what your home might be worth based on Zillow’s national median error rate of 6.9% (for off-market homes).

How accurate is Zillow vs. an appraisal?

Who completes it?ComputerLicensed appraiser
What does it cost?Free$350 - $500
How long does it take?Instant1-2 weeks
How accurate is it?SomewhatVery

A Zestimate is considered less accurate than a professional home appraisal.

It’s a computer-generated home value estimate based on publicly-available data, while an appraisal is a property valuation completed by a state-licensed appraiser.

Appraisals are more hands-on than home value estimators. The appraiser usually visits the house in person for an inspection, noting any value-adding features or upgrades.

A Zestimate is based on an algorithm that incorporates public and user-submitted data. It’s not created by a real estate professional like an appraisal is, so errors are more common.

Zillow even states on its website, “The Zestimate is not an appraisal and can’t be used in place of an appraisal.”

How Zillow’s home value estimator works

Zillow’s access to housing data is a key advantage over its peers. It has data on over 110 million homes and publishes Zestimates on 104 million of them, with home values updated multiple times per week.

The company incorporates data from county and tax assessor records, as well as hundreds of multiple listing services (MLS) and real estate brokerages. Its data includes:

  • Home characteristics: Beds, baths, square footage, and location.
  • On-market data, including listing price, and days on market.
  • Off-market data obtained through publicly available records.
  • Current market trends in your area.

All of this data provides users with a Zestimate, a high and low estimated market value, and the value per square foot of a property.

What are comparable sales?

Like other home value estimators, real estate agents, and professional appraisers, Zillow also factors comparable sales or “comps” into its valuations.

Comps are recent home sales that are most similar to the subject property, factoring in its location, beds, baths, condition, and square footage.

Is Zillow's Home Value Estimator Accurate? The Truth Revealed! (5)

Zillow usually includes up to five comps in its Zestimate. Each comp includes information impacting the subject home’s value, such as sale price, sale date, and square footage.

Useful homeowner dashboard

Zillow has one of the most useful homeowner dashboards of any home value estimator, as it includes:

  • A chart of how your home’s value has changed over time;
  • A list of comparable home sales, with key property information;
  • Your estimated home equity, based on your property’s current value and remaining mortgage balance;
  • An estimated net proceeds calculator to show you what you might earn in a home sale.

To claim your home, create a free Zillow account (if you don’t have one yet), and click “unlock homeowner dashboard” on its listing page.

Is Zillow's Home Value Estimator Accurate? The Truth Revealed! (6)

You can then update any incorrect or missing information. If you feel your home value estimate is way too low, there’s likely a good reason why.

Is Zillow's Home Value Estimator Accurate? The Truth Revealed! (7)

For example, we noticed a 500-foot shortage in Zillow’s finished square feet for our test property. Updating that information should lead to a higher Zestimate.

Besides finished square feet, you can also update your home’s beds, baths, lot size, year built, HOA dues, and basement or garage square footage.

Choose your comps

Another useful feature is the ability to pick your comparable home sales to receive a “private estimate,” which should be more accurate than its automated estimate.

Simply click “pick comparable homes” on your homeowner dashboard to get started.

Is Zillow's Home Value Estimator Accurate? The Truth Revealed! (8)

It brings you to a new screen with a list of eight to 10 recent home sales in your area, including each home’s key information (beds, baths, sq. ft., and sale price per sq. ft.)

Is Zillow's Home Value Estimator Accurate? The Truth Revealed! (9)

Scroll through each home and choose the most relevant sales by clicking “add to my estimate.” A good target is 2-3 homes that are most similar to yours, and those that have sold within the past few months.

Zillow makes choosing your comps easy as it compares your home and its comps line-by-line, listing each home’s key information (beds, baths, sq. ft., etc).

You can also view each listing on Zillow to compare interior photos and choose a home that’s similar to yours in condition and upgrades.

Why a Zillow Zestimate is far from perfect

While we’re impressed with Zillow’s features, its Zestimates weren’t always accurate. Here are a few likely reasons why a home’s Zestimate might be off by thousands of dollars.

Incorrect or missing data

Zillow’s home value estimates are only as accurate as its available housing data, which could be outdated or flat-out wrong – especially on off-market properties that haven’t sold in a long time.

For example, a home’s property taxes paid, tax assessed value, or interior square footage could be wrong or missing on Zillow and hold down its value estimate.

It’s up to homeowners to update their property tax records and edit their home facts on Zillow to reflect the most up-to-date information.

Home renovations aren’t considered

Home value estimators often fail to give homeowners credit for additions, remodels, or major home repairs. Zillow is no exception.

According to Zillow, “Unreported additions, updates, and remodels aren’t reflected in the Zestimate.” It’s impossible for Zillow’s computer algorithm to know if you’ve upgraded your kitchen, added a bathroom, or replaced your roof.

For example, remodeling an attic or finishing a basement could add hundreds of livable square feet to your home and tons of value. Your home’s Zestimate doesn’t reflect those home improvements unless reported to your local tax assessor.

Irrelevant or outdated comps

Our research found that Zillow often uses comps that have sold more than six months ago, or just aren’t that similar to the subject property.

A comparative market analysis (CMA) report and a home appraisal rarely ever use comps that have sold six months or longer from the date of the report, as the data is considered outdated.

A real estate agent or appraiser also pulls data directly from their local multiple listing service (MLS), which has the most accurate and up-to-date sales information, while Zillow often relies on tax records or user-submitted data.

Zillow home value estimator: Pros and cons

✅ Pros❌ Cons
Fast and easy to useListing data is often inaccurate
Accurate compared to peersRenovations don't change a home's value
Home values updated frequentlyOften uses the wrong comps
Useful owner dashboard

✅ Pros

Fast, free, and easy to use

Zillow’s website makes it easy to get a free home value estimate within seconds.

You don’t need to enter your contact information to get your estimate, either. Most of Zillow’s on-market and off-market properties have a Zestimate directly on their listing page.

However, you do need to provide your full name and phone number to claim your home and edit its facts on Zillow.

Accurate compared to its peers

Zillow’s error rate for on-market homes is 1.9% and for off-market homes is 6.9%. Its accuracy compares favorably to its peers, including Redfin, which has an error rate of 2.61% for on-market homes and 7.67% for off-market homes.

However, like Redfin and its competitors, Zillow’s accuracy rates vary widely by location and are much lower in states with more recent home sales.

Home values are updated often

Zillow’s home values are updated multiple times per week, except on rare occasions, like if the company is making changes to its Zestimate algorithm.

Useful homeowner dashboard

Zillow provides more than just a home value estimate. Its owner dashboard provides useful sales information, including a home value chart, a list of your home’s comps, and an estimated net proceeds calculator.

You can also correct your home’s key information – such as its beds, baths, and square footage – to get a more accurate estimate.

❌ Cons

Inaccurate or outdated data

Several of our test properties had incorrect or missing data compared to their tax records. Zillow relies on the MLS, tax records, and its users, which are far from perfect data sources.

For example, several of the homes we tested had the wrong square footage or the incorrect number of bedrooms or bathrooms.

However, these inaccuracies are pretty common with all home value estimators, not just Zillow.

Renovations don’t impact your home’s value

Zillow is likely undervaluing homes with recent upgrades or additions.

The company allows users to add a structural remodel to a home’s key information. But there’s no option to add other major home improvements that boost a home’s value like a kitchen or bath remodel.

However, this is a common issue among home value estimators, so the problem is not specific to Zillow.

Comps are often irrelevant or outdated

Like other home value sites, Zillow does not always use the most recent or relevant home sales data to determine its estimates.

We tested several off-market properties and found that their comps included multiple homes that sold more than six months ago.

Zillow also regularly uses home sales located more than 1 mile away from the subject property, and in different neighborhoods.

(Video) Zillow Home Estimate (Zestimate) - The Truth EXPOSED

Zillow home estimate vs. CMA

We put Zillow’s home value tool to the test, comparing its Zestimate with our own CMA based on publicly-available sales data.

For our example, we used a random off-market, single-family home in a popular suburb of Summerville, SC. Our subject property has four beds, three baths, and 2,106 interior square feet.

Zillow determined that this off-market house has an estimated value of $427,500. Its home value estimate is based on its selection of five comparable home sales.

Zillow comps

Property Sales priceLast sale dateBedsBathsSq. ft.
Comp #1$475,0003 months432,291
Comp #2$350,00012 months432,076
Comp #3$399,0001 month432,485
Comp #4$400,00012 months432,356
Comp #5$515,0003 months432,802

Zillow used two comps that sold 12 months ago, which is far too outdated to use in a home valuation (real estate agents and appraisers typically only use closed sales of up to six months).

We ran the numbers with our own CMA report and determined the home has an estimated value of $426,333. We chose the three most recent, relevant comparable home sales in the area.

Our comps

Property Sales priceLast sale dateBedsBathsSq. ft.
Comp #1$475,0003 months432,291
Comp #2$399,0001 month432,485
Comp #3$405,0001 month432,333

Our numbers are pretty close to Zillow’s estimate. However, we think the subject property’s value is likely much higher than that based on its condition and upgrades.

After reviewing its online photos, we found that the subject property has a fully-updated kitchen with granite countertops and new stainless steel appliances (its comps do not.) The homeowner also installed new flooring.

Is Zillow's Home Value Estimator Accurate? The Truth Revealed! (10)

An upgraded kitchen is worth approximately $20,000 in this market, lifting our home value estimate to $447,500.

How the numbers compare

We plugged the property into several other home value websites to see how the valuations compare. Here’s an average of the home’s value from all six sources.

Bank of America$426,823
Our estimate$447,500
Average value$426,212

Why the big value difference?

The property’s estimated value ranges from $410,400 to $447,500. Here’s why home values fluctuate based on the estimator:

  • We carefully selected our three comps, only choosing home sales that have closed within the past three months.
  • The home value estimators all used several outdated comps, including several homes that sold 12 months ago.
  • Chase had the lowest estimated value; it did not have the correct number of bedrooms listed.
  • We gave the home credit for its recently upgraded kitchen; Zillow and other home value estimators did not appear to do so.

Ultimately, an experienced realtor or appraiser knows your market much better than an automated home value estimator. A realtor can give you credit for any of your home’s renovations or upgrades.

How Zillow’s home value estimator compares

Zillow vs. Redfin estimate

Zillow and Redfin are two top home value estimators, providing home values for more than 100 million properties.

Zillow Zestimates have higher median accuracy rates for both on-market and off-market properties and cover more homes in rural areas or markets with fewer home sales.

Zillow vs. Chase

Zillow’s home value estimator also compares favorably to Chase’s. We found Zillow’s homeowner dashboard to be much easier to use and more insightful.

For example, while you can edit your home’s information on Chase, the website won’t save your edits.

Zillow also covers far more homes than Chase, as Zillow currently covers more than 104 million properties, while Chase claims it has millions of records in its database.

Zillow vs. Realtor

Realtor’s home value estimator pulls data from mortgage lenders, which it says makes it more accurate than its competitors.

However, unlike Zillow, the company does not currently publish a median error rate, making it hard to compare its accuracy.

We also ran multiple test properties through its estimator and found the home values less accurate than Zillow’s.

How to get an accurate home valuation

Compare home values from multiple sites

Zillow is just one of about a dozen home value estimators. Each pulls different data to determine a home’s value.

Zillow home value estimator: FAQs

Does Zillow provide an accurate estimate of home value?

A Zillow estimate is more accurate than many other real estate websites, with a low nationwide median error rate of just 1.9% for on-market properties. But Zillow home values are often based on outdated comparable properties and incorrect or missing data.

Unlike a CMA from a realtor or an appraisal, Zillow's home values are based on a computer algorithm.

Ultimately, Zillow Zestimates provide a good starting point for a homeowner or home buyer interested in learning more about a property. Readers looking for a more professional, accurate home value estimate can find a local realtor through an agent-matching service, like Clever Real Estate.

What is the most accurate home value estimator?

Zillow is widely considered the most accurate home value estimator. It has a median error rate of just 1.9% for on-market properties and 6.9% for off-market homes, slightly lower than Redfin.

However, this still means that Zillow Zestimates could be off by thousands of dollars, especially compared to a CMA report from a local realtor, or a professional home appraisal.

Should I trust Redfin or Zillow home value estimates?

Home sellers and buyers can use real estate sites like Redfin or Zillow for a quick ballpark home value estimate. But the site's property values aren't always trustworthy and shouldn't be relied upon in a real estate transaction.

Local real estate agents or appraisers are much more likely to provide you with an accurate home estimate, especially when compared to Zillow's Zestimate or a Redfin estimate.
For example, a realtor or broker factors in local market conditions, and can give a home credit for its upgrades or renovations.
