Redfin and Zillow are two popular real estate platforms. There is a constant debate about Redfin vs Zillow estimates. Each offers values that may differ due to factors like accuracy, home types, advice, resources, and the impact of renovations.
As of right now, Redfin is marginally more accurate.
Zillow and Refin’s home value estimators utilize a proprietary formula based on public and user-submitted data.
The main concern is that both estimators lack accuracy in determining the price of your home before it is listed for sale. In the home buying-selling process, this isn’t something you want to get wrong.
Each platform has unique ways of calculating values, which may contribute to slight pricing differences. For instance, Zillow might give a higher value to a newly renovated kitchen than Redfin.
But don’t let the numbers fool you; it’s about more than just the estimate. Understanding how each system works before deciding which one serves your needs best.
According to recent data, the Redfin Estimate has shown to be slightly more accurate than Zillow’s Zestimate. However, consulting with a local real estate agent for a comparative market analysis (CMA) is recommended for the most precise home value estimate.
From many years of experience as a Realtor, it is a mistake to trust online value estimators. None of them deliver the estimate accuracy needed to make significant financial decisions.
When you need an accurate home value, turn to the expertise of a local professional. Top Realtors and appraisers who have years of experience can provide far more precise estimates.
Let’s examine everything you should know in comparing Redfin to Zillow.
Essential Facts to Know
1. Redfin and Zillow are popular real estate websites that estimate property values.
2. Both Redfin and Zillow use algorithms to generate pricing estimates based on various factors such as location, size, and recent sales data.
3. Redfin claims to have a more accurate estimate by incorporating data from multiple listing services and direct access to MLS databases.
4. Zillow estimates, often called “Zestimates,” have faced criticism for their accuracy, with some properties being overestimated or underestimated.
5. Ultimately, comparing Redfin and Zillow estimates can help buyers and sellers better understand a property’s potential value but should be used as just one piece of information in the decision-making process.
Comparing The Basics of Zillow vs Redfin
Zillow and Redfin offer popular online real estate services, including property value estimates known as “Zestimates” on Zillow and “Redfin Estimates” on Redfin.
Here are some points comparing the site studies on these estimates:
Data Sources and Algorithms
- Zillow: Zestimates are calculated using a proprietary formula considering public and user-submitted data. Zillow continually updates its algorithm to improve accuracy.

Accuracy
- Zillow: The accuracy of Zestimates varies by location and data availability. Zillow publishes an accuracy report stating that half of their Zestimates are within a certain percentage of the selling price, and half are outside that range.
- Redfin: Redfin also publishes its median error rate for on-market and off-market homes. It claims a higher accuracy than Zillow, especially for homes listed on the MLS.
Update Frequency
- Zillow: Zestimates are updated daily, but the actual time it takes for information to reflect in the estimate depends on the data availability and processing.

Professional Involvement

- Redfin: As a brokerage, Redfin has real estate agents who can provide professional insights, potentially leading to more accurate estimates.
Criticism and Limitations
- Both platforms receive criticism for the accuracy of their estimates, especially for unique homes or areas with less real estate activity. These estimates are best used as a starting point. They should be supplemented with professional appraisals and local market analysis.
It’s important to note that while both Zestimates and Redfin Estimates provide valuable information, they are not appraisals and should not be the sole basis for any real estate decision.
Real Estate agents are always asked, “Are Zillow’s estimates accurate?”
The accuracy and usefulness can vary greatly depending on the specific property and local market conditions.
What is an Online Home Value Estimator?
Online home value estimators are tools used to approximate a property’s value. The estimation is based on location, size, age, and recent sales of comparable properties.
Zillow estimate is known as a “Zestimate.” Redfin’s are called “Redfin estimates.”
These estimators utilize algorithms and data analysis to estimate a home’s value. Redfin and Zillow estimators offer homeowners and potential buyers a starting point for understanding the market value of a property.
Users input specific details about their homes. For example, the number of bedrooms, bathrooms, and square footage, and the estimator uses this information to calculate an approximate value.
These estimators can be helpful for homeowners looking to sell their property. Prospective buyers who want to know a home’s value before making an offer can also utilize the tool.
While online home value estimators can be a helpful starting point, it’s important to note that they are not a substitute for a professional appraisal.
Factors such as the property’s condition, unique features, and market trends may not be fully captured by these estimators. It’s always recommended to consult with a real estate professional for a more accurate valuation.
From experience in the real estate industry for nearly forty years, it is imperative to rely on professionals. Online estimates are entertaining to look at, but nothing more.
Redfin vs Zillow: A Comprehensive Comparison
When it comes to estimating home values, Redfin and Zillow are both leading platforms, each with their unique approaches.
To analyze which platform might suit you best, it’s essential to consider several key factors.
They include the following:
- Accuracy of each
- Advice for home buyers and sellers
- Resources available
- The impact of renovations
By examining these aspects in detail, we can gain valuable insights that aid in making informed decisions regarding real estate transactions.
Accuracy
In examining Redfin vs Zillow, one of the most crucial factors to consider is the accuracy of the estimates provided by each platform.
An analysis of the median error rates for on-market homes reveals that Redfin boasts an error rate of 2.09%. Zillow’s error rate is slightly higher at 2.4%.
Although both platforms strive for precise estimates, this error rate difference could significantly impact buyers and sellers’ decision-making.
It’s important to note that Redfin updates on-market property estimates daily and off-market estimates weekly. They provide more frequent updates than Zillow.
The off-market median error rate for Redfin was 6.45 percent vs Zillow at 7.49 percent. According to research, Redfin was more than 1 percent more accurate for off-market homes.
| Comparison R vs Z | Redfin | Zillow |
|---|---|---|
| On-market median error rate | 2.1% | 2.4% |
| The off-market median error rate | 6.45% | 7.49% |
What Does Median Error Rate Mean?
Redfin and Zillow utilize median error rates as a measure of accuracy for their home value estimations. These rates gauge the degree of alignment between the estimates provided by Zillow and Redfin and the actual home values.
Notably, both platforms demonstrate greater accuracy in estimating the values of active listings compared to off-market homes.
Zillow’s median error rate for active listings is 2.4%, indicating that the Zestimate will be within 2.4% of the sales price for half of its on-market listings. Zillow provides media error rates for all states in this resource.
Conversely, the other half will not be within this range. For off-market listings, Zillow’s median error rate is 7.49%.
Redfin’s median error rate for active listings is 2.09%. This indicates that Redfin Estimates for 50% of on-market homes are within 2.09% of the sales price, while the remaining 50% are not. The error rate increases to 6.45% for off-market homes.
Real Estate Agents or Appraisers Can’t Be Off Like That
As I have said many times in the past, real estate agents and appraisers can’t be off by 6-7%. Consumers rely on our expertise to make sound decisions.
Being off by that much would cause poor decision-making. It could lead to devastating financial consequences like overpaying or missing out on properties.
Massachusetts real estate agent Kevin Vitali weighed in with the following experience.
“Bill Automated Value Models like Zillow and Redfin remove the human element that helps determine the accurate value of a home. The algorithm can’t determine the condition, location, overall appeal, or other home features that an appraiser or real estate agent can see during a visit to a home.
Each feature can substantially impact the home value but cannot be assessed by a computer model.
Sites like Redfin and Zillow may get you in the ballpark, but at the end of the day, the value can be as much as 30% off. For example, a recent listing of mine in Haverhill, MA, had a Zestimate of $535,000.
After gathering comps and preparing a comparative market analysis, I determined the home was worth $610k to $620k. The house was listed for $600,000 and sold for $625,000. Zillow underestimated the value of the home by almost a whopping 18%!
Use Zillow for preliminary planning, but once you get serious, bring in an agent to get you a more accurate value.”
I share Kevin’s sentiments and have had the same experiences far too many times.
Coverage of Properties
In addition to accuracy, reviewing the types of homes each platform covers is vital. Both Redfin and Zillow feature a vast database of property listings. However, they may differ in coverage for specific property types or regions.
Understanding these nuances can be crucial for individuals seeking or selling niche properties or properties in less familiar areas.
Consider a scenario where someone wants to sell a rural property or a unique architectural gem. The coverage offered by each platform could greatly influence their ability to attract potential buyers.
Exploring Accuracy: Redfin Estimate vs Zillow Zestimate
When determining the market value of a home, accuracy is crucial. The estimates provided by Redfin and Zillow directly impact the decisions made by potential buyers and sellers.
It’s important to note that Zillow used to be more accurate than Redfin but has experienced a significant decline in accuracy rates in recent years. However, while Redfin tends to outperform Zillow in terms of accuracy on average, there are instances where Zillow’s estimations might align better with actual sale prices.
This variance highlights the complexities involved in accurately estimating the value of a home, especially in dynamic real estate markets.
Additionally, it’s essential to consider both platforms’ geographic coverage and data sources. Redfin offers precise home valuations for properties within its local market areas.
On the other hand, Zillow covers a broader range by including data from entire counties. The wider geographic scope enhances Zillow’s property coverage but may sacrifice some precision compared to Redfin’s localized focus.
Realtors constantly field questions like, “Why is my Zillow estimate changing?”
Understanding these accuracy statistics and nuanced differences between Redfin’s estimates and Zillow’s Zestimates provides valuable insights for potential buyers and sellers evaluating their options in the housing market.
As we venture deeper into understanding home valuation dynamics, let’s shift our focus to unraveling the intricacies associated with different home types and their corresponding estimates.
Diving Into Home Types and Their Estimates
When determining a home’s worth, it’s essential to recognize that not all properties are equal.
Different property types, such as single-family homes, condos, townhouses, and off-market properties, may have varying accuracy levels in their estimates on Redfin and Zillow.
Understanding how these estimators perform across different property types can provide valuable insights for homeowners and potential buyers.
It’s crucial to understand that different property types require distinct valuation methodologies.
Single-family homes are typically evaluated differently than condos or townhouses. The uniqueness of these properties often means that estimators like Redfin and Zillow utilize different sets of criteria when providing their estimates.
For example, the individual characteristics of single-family homes, such as lot size, yard space, and privacy, are significant factors that contribute to their valuation.
On the other hand, condos and townhouses may be valued based on their shared amenities and association fees.
This distinction isn’t just for formality. It has real-world implications for homeowners and buyers who want to understand home values.
Inaccurate estimates can lead to unrealistic expectations or missed opportunities for sellers and buyers.
Understanding how the estimates differ across these diverse property types empowers individuals better to navigate the complexities of the real estate market.
In-depth Review: Redfin vs. Zillow’s Resources
As a potential home buyer or seller, accessing accurate and up-to-date information while navigating the real estate market is crucial.
Redfin and Zillow offer a range of additional features that extend beyond property listings. They give users valuable insights into neighborhood trends, market analysis, and specific property details.
You can make informed decisions by understanding the scope of resources each platform offers. You’ll also gain a deeper understanding of the real estate landscape in your desired area.
Both Redfin and Zillow aim to empower users with a wealth of supplementary information facilitating decision-making.
For instance, they provide detailed neighborhood insights, enabling users to explore local amenities, school ratings, crime statistics, and community demographics.
Market trend data helps users stay abreast of fluctuations in housing prices, inventory levels, and sales trends within specific areas.
Property Details Are Exceptional
The property details on these platforms offer extensive information. You will see square footage, lot size, tax assessments, sales history, and, in some cases, even virtual tours or 3D walkthroughs.
Users can identify each platform’s unique strengths when comparing Redfin and Zillow’s resources. For instance, Zillow may offer a broader range of property listings.
Redfin’s emphasis on direct transactions through its website provides a streamlined approach for buyers and sellers.
In essence, both platforms present an extensive array of resources that cater to the diverse needs of individuals navigating the real estate market.
By leveraging these tools effectively, users can gather profound insights aiding in well-informed decisions regarding property transactions.
Understanding the nuances of these additional features is pivotal for leveraging the full spectrum of available data. It helps make informed real estate decisions.
Impact of Renovations and Additions on Estimates
Making changes to your home is a significant decision. Even more so when considering renovations or additions to increase your property’s value.
Many homeowners wonder how these improvements will affect the estimated value provided by platforms like Redfin and Zillow.
It’s not just about making your home feel more comfortable or attractive—it’s about potentially increasing its market worth.
Importance of Property Upgrades in Estimate Calculations
Redfin and Zillow consider upgrades and improvements when estimating a home’s value. If you’ve invested in new appliances or a kitchen remodel, you’d want that reflected in your home’s estimated value, right?
However, it’s essential to understand precisely HOW these estimators evaluate property upgrades.
Redfin’s Approach
Redfin bases its estimates on various factors, including public data, user submissions, and knowledge from real estate professionals. Additionally, they also consider a property’s unique features and specific characteristics.
Any renovations or additions could be reflected in their estimate if they add substantial value to the property.
Zillow’s Method
On the other hand, Zillow uses a feature called “Zestimate.” As mentioned, the estimation algorithm calculates the market value based on public and user-submitted information.
They also allow homeowners to update their home details, including recent renovations or additions. Considering that Zillow considers user-provided data, adding information about your property’s updates could also influence their estimate.
So, both platforms consider property upgrades in their estimates. However, it’s important to note that these estimations are just that—estimates. They might not always reflect the exact amount you spent on upgrades.
It’s always a good idea to consult a real estate professional to understand how renovations impact home value.
Homeowners can better gauge the potential investment returns by understanding how these estimators evaluate property upgrades. They can make more informed decisions about their properties.
Understanding how home value estimators work can help homeowners make educated decisions about their properties and investments for the future.
Why Do Zillow and Redfin Home Values Differ?
Zillow and Redfin estimates vary due to their utilization of distinct models. The details of these models are safeguarded through non-disclosure agreements.
Only Zillow and Redfin’s upper-level employees comprehensively understand their inner workings. There are pros and cons to each.
Here is a simple list of how these real estate companies produce different results:
- Differing algorithms
- Redfin has direct access to the Multiple Listing Service (MLS)
- Redfin covers fewer homes than Zillow
- Update frequency is more frequent at Redfin
- Market change assessments are not treated the same
- Accuracy of using home improvement information
On an individual house level, one buyer could place more value on a house than another. It is as simple as that.
How Can You Improve The Accuracy of Redfin and Zillow Estimates?
If you find your Redfin Estimate or Zillow Zestimate inaccurate, you can edit your home facts on either platform.
Updating your property information should enhance the accuracy of an estimate that contains outdated or incorrect details.
To edit your home facts on Redfin, click on your property page and Edit Home Facts.
This process involves proving that you are the property owner, so you must provide your contact information to Redfin.
To modify your home’s listing on Zillow, sign up for a free account and select “unlock homeowner dashboard” on the listing page. From there, you can adjust your home’s bedrooms, bathrooms, finished square footage, lot size, year of construction, and other details.
The Best Methods For Calculating Accurate Home Values
When you want an accurate home value, never trust the accuracy of online value estimators such as Zillow and Redfin. Instead, you should hire a local real estate professional for assistance.
Either a skilled Realtor or appraiser. It becomes vital not to work with just anyone. The quality of real estate agents from the top of the spectrum to the bottom is significant.
The value presented may not be better than an online estimate without choosing the right agent. It takes years of experience in pricing properties.
To arrive at accurate house prices, you must know how to adjust based on comps. Errors happen without this skill set.
Every day, I see countless real estate listings across the country reduced in price. Many of these are pricing mistakes by real estate agents.
When you must have an unbiased opinion, an appraiser is an excellent choice.
Alex Capozzolo, a Philidelphia investor and Realtor, weighed in with his experiences.
“Bill, you could never rely on these estimates as an investor. I bought a home not long ago, and after careful analysis, my research showed that the house was worth $20,000 and $25,000 less than the estimates shown at Zillow and Redfin.
Trusting these house values would have cut into my profit margin by a significant amount. It would not have been worth flipping the property.”
Conclusion
Take the home value estimates presented on the Redfin and Zillow platforms with a touch of skepticism. Could the value be close? Yes, it is possible. It is also just as likely to be way off.
Making significant life decisions should not be based on an automated valuation opinion. If you are in the Metrowest, Massachusetts, area and are considering selling your home, I would be happy to provide an accurate property value assessment. Feel free to contact me.

Josephine – you are 100 percent correct. It is too bad so many people do not realize this fact.
Relying solely on Zillow or Redfin for home value estimates? Big mistake. These platforms might be convenient, but they’re not hitting the mark for accuracy. Here’s the deal: algorithms can’t catch everything, especially the unique features of your home or the latest market shifts. You’ve got renovations? Good luck getting those accurately reflected without a real person checking things out.
And about those “median error rates” – they’re a fancy way of saying these estimates can be way off, potentially costing you thousands when it comes to real buying and selling decisions. What’s worse is people treat these numbers like gospel.
The real MVPs? Local real estate pros. They’ve got the experience, they know the neighborhoods, and they can actually walk through your house. Online estimators can’t do that. If you’re serious about getting your home’s value right, skip the online guesswork and talk to someone who actually knows what they’re doing.
You nailed it!
