Redfin Vs Zillow: Which Estimator Should You Trust?

Aspiring homebuyers are increasingly heading to real estate listing sites like Zillow and Redfin to put bids — or at the very least to satisfy their curiosity about the current market before investing. These platforms are helpful since they enable users to research alternatives without leaving their sofa.

When preparing your home buying transaction and comparing prices, Zillow or Redfin might be a convenient option. Before you randomly select one of these two platforms, you should research them to make a better-informed decision about which one is ideal for you.

What Is Zillow?

Zillow is an online real estate marketplace and one of the most popular sites in the United States for locating property listings and comparing housing prices. 

Unlike Redfin, Zillow permits For Sale By Owner, or FSBO, listings, which allows sellers to avoid paying agent commissions. Because of FSBO listings, you might discover unique listings on Zillow that aren’t accessible on other prominent sites.

When it comes to buying, Zillow features a feature known as Zillow Offers. It lets you make cash proposals to sellers to move your closing date forward. This option is available in over 25 markets, and vendors must fill out an eligibility form to participate.

What Is Redfin?

Redfin is a brokerage platform only available in a few places in the United States. This website features agents who operate on cheaper commission rates than other realtors. That’s why a site like Redfin might save you thousands in real estate fees if you’re selling a home. After you purchase a house via our website, you may be eligible for a buyer’s rebate when the transaction is completed.

Redfin also offers a iBuying service known as “Redfin Now.” This application enables buyers to make a cash offer and close on the purchase they want quicker than if they used a conventional broker.

This platform also provides a “Redfin Refund” when linking buyers with Redfin realtors who pay cashback upon completing a sale depending on the property’s cost and other market factors.

Is Zillow Or Redfin More Accurate?

Redfin’s house value calculator outperforms Zillow’s when determining the sales price. According to Redfin, their estimates for listed houses are generally 74% accurate, within 5% of the sales price. For instance, Zillow is just 67% accurate within 5% of the listed home’s selling price.

Redfin used to be more accurate than Zillow. However, its Zestimate accuracy rates for sales within 5% of the asking price fell considerably year over year, from 82% in 2021 to 67% in 2022.

When compared to Redfin, Zillow’s estimations vary by around 7 percentage points.

The home value algorithms used by Zillow and Redfin are more dependable for broad estimates than exact ones. When guessing within 20% of a home’s selling price, both businesses are pretty accurate – around 98% of the time. When thinking within 5% of the sales price, the accuracy declines to 67-74%.

Home value estimates from Zillow and Redfin differ by location as well. Suppose you want to look for margins of error near you. In that case, Zillow publishes them at the national, state, and metropolitan levels. Redfin also publishes federal and state accuracy statistics by county rather than metro region.

Why Are Zillow And Redfin Estimates So Different?

Simply put, Zillow and Redfin estimates vary because they use different methods. No one outside of Zillow and Redfin, who have signed nondisclosure agreements, knows the specific inner workings of those models.

According to Redfin, a Redfin Estimate only provides “enough comparable houses sold nearby within the recent year.” According to Zillow, its Zestimates “rely on far more than similar sales in a particular location.”

Overall, there are three key reasons why Zillow and Redfin house estimates differ:

•  The number of houses inspected

•  Market circumstances

However, the house value estimates provided by Redfin and Zillow should not be significantly different for the same property. If that’s the case, one site may have false or out-of-date information about the property. Zillow and Redfin enable users to alter house details, but you must first declare the property as an owner.

Zillow Covers More Homes Than Redfin:

Officially, Redfin claims to give home value estimates for over 92 million properties. Still, its weekly updated data suggests it’s closer to 97.6 million – only approximately 1.3 million of which are current listings. Redfin is present in 43 states as well as the District of Columbia.

In comparison, Zillow estimates over 104 million houses across all 50 states. The bulk, like Redfin, is off-market, with just 1.5 million current listings.

It’s also worth mentioning that Zillow analyses data from a far greater geographic area than a typical realtor or appraiser would – instead of only utilizing comps from your neighborhood to construct its Zestimate, Zillow may take data from an entire county.

Redfin and Zillow cannot account for renovations and additions if they are not disclosed, nor can they assess the quality of such improvements or prospective purchasers’ perspectives.

In addition, properties sell quickly and for much more than the asking price in hot markets. This may make precise estimations for home value estimator algorithms problematic.

Error Margins And Accuracy Updates:

Redfin’s house value estimator median error rates are around 0.6% higher than Zillow’s. Therefore the two estimates are almost identical in practice.

However, Zillow does not provide as often updates to their accuracy or error margins as Redfin. On July 10, 2022, Zillow updated its accuracy figures, and Zillow’s accuracy ratings were last updated on May 27, 2021. Redfin updates its accuracy rates regularly.

Zillow And Redfin Vs. Hiring A Realtor:

Whereas Zillow and Redfin utilize automated data points to estimate a home’s worth, a realtor inspects the property in person and is familiar with the local market. Both use CMAs, but a realtor’s comps will be more accurate.

Home estimators like Zillow and Redfin can only analyze so much — often by square footage and the number of bathrooms. Zillow claims to utilize the listing description as well, although it does not specify how.

Zillow’s and Redfin’s estimations are based on the volume and freshness of data in your market. If one site has incorrect data, the price projection will suffer.

Realtors have access to the most accurate and up-to-date information, frequently via networking with other brokers and knowing surrounding houses. Listing agents seek comparable-sized dwellings and properties with comparable attributes in your community using comps. Algorithms cannot detect warped flooring or carpeted bathrooms, which might cause Zillow and Redfin estimates to differ.

If your property for sale is unique to the region, algorithms may struggle to give reliable estimations. Estimating the cost of a brick ranch in a suburb full of brick ranches is simpler than calculating the price of a Queen Anne in a neighborhood full of salt boxes and craftsman houses.

Instead, we suggest looking for a knowledgeable real estate agent who knows the prices of properties in your area.


Zillow and Redfin are reputable organizations that provide good services to buyers and sellers. Your specific requirements determine the best option.

Keep in mind that Redfin may be able to provide more accurate estimates due to the technologies they utilize to acquire price information. Because they are a bargain brokerage with expertise in negotiating rebates and reduced commissions, they can also obtain you with cheaper pricing.

If you want to locate unique properties and prepare to deal directly with the seller rather than an agent, Zillow may be the way to go.
