Zillow vs. Redfin Estimates: Which is More Accurate?
In today’s digital age, when looking to buy a home, sell a property, or simply curious about the potential value of a house, many turn to online home valuation tools. Two of the most popular platforms offering these tools are Zillow and Redfin. Both sites provide property estimates, but which one should you trust more? Let’s dive into the Zillow “Zestimate” and Redfin “Redfin Estimate” to compare their accuracy and methodologies.
Zillow’s Zestimate
What is it? The Zestimate is Zillow’s home valuation model, aiming to provide an estimated market value for homes across the U.S.
How is it calculated? Zillow uses a mix of public property records, recent sales, tax assessments, and proprietary algorithms. Their model is continually updated and refined based on new data and feedback.
Accuracy: Zillow is transparent about its accuracy, with a data coverage and Zestimate accuracy table to guide users. Depending on the region, the median error rate can vary.
Redfin’s Estimate
What is it? The Redfin Estimate is Redfin’s automated home valuation tool, which offers market value estimates for on-sale and off-sale properties.
How is it calculated? Redfin’s algorithm considers more than 500 data points, including market activity, historical home details, and local pricing trends.
Accuracy: Redfin claims its median error rate for on-market homes is below 2%. They also offer an interactive map that displays their pricing accuracy by region.
Comparison:
- Data Sources: While both Zillow and Redfin rely on MLS (Multiple Listing Service) data and public records, Redfin, being a brokerage, has direct access to MLS data, which may offer more timely updates.
- Updates: Redfin’s estimates tend to be updated more frequently due to its direct MLS access. Zillow, however, relies on a mixture of public data and user-submitted information.
- User Interface: Zillow offers a more detailed breakdown of how it arrives at its Zestimate, including factors that increased or decreased the value. Redfin focuses more on local market trends and comparables.
- Coverage: While both tools cover a broad swath of the U.S. market, there might be specific regions where one is more accurate than the other due to the density of data points and local partnerships.
Recommendations:
- Use Both: For a well-rounded view, consider checking both Zillow and Redfin. The variance between the two estimates can provide a more comprehensive range of potential values.
- Professional Appraisal: Online tools are excellent starting points, but for the most accurate valuation, consider hiring a professional appraiser or seeking a CMA (Comparative Market Analysis) from a local realtor.
- Stay Updated: Both platforms continually refine their algorithms, and property values can change. Regularly checking both sites can give you a pulse on the current market.
Conclusion
Both Zillow and Redfin offer valuable tools for estimating home values, each with its strengths and weaknesses. While Redfin might have a slight edge in areas with direct MLS access, Zillow’s vast database and comprehensive breakdowns are also noteworthy. Ultimately, users should treat online estimates as informed starting points and seek professional opinions for significant property decisions.
