Frequently Asked Questions

List on both — there's no cost to list on either platform as a seller working with an agent, and your listing will typically appear on both automatically when your agent inputs it to your local MLS (Multiple Listing Service). The MLS syndicates to Zillow, Realtor.com, Redfin, Trulia, and hundreds of other sites simultaneously. If you're selling For Sale By Owner (FSBO), you'll need to manually submit to each platform or pay a flat-fee MLS service that distributes to all. Priority advice: focus on your MLS listing quality (great photos, accurate details, virtual tour) — everything else is automatic distribution.
Zillow's Zestimate has a median error rate of approximately 2.4% for on-market homes (homes with an active listing on Zillow) and 6–7% for off-market homes. In practical terms: on a $400,000 home, a 2.4% error = $9,600 average variance. However, these are medians — in fast-moving markets, unique properties, or areas with limited sales data, Zestimates can be off by 10–20%+ or more. The Zestimate is a starting point for research, not a substitute for a comparative market analysis (CMA) from a local real estate agent or a professional appraisal. Many sellers and buyers over-anchor to the Zestimate; a local agent who knows the neighborhood and recent comps is more reliable for actual pricing decisions.
Realtor.com features agent profiles connected to the National Association of Realtors (NAR) database, offering verified credentials and MLS access details, while Zillow also provides agent information but with less emphasis on NAR verification. For finding agents with proven MLS experience and local market expertise, Realtor.com's integration with official NAR data typically provides more authoritative professional credentials, though both platforms allow you to contact and compare agents directly.
Expert Analysis: Zillow vs Realtor.com
Realtor.com and Zillow are the two largest real estate search platforms in the United States, competing for the attention of home buyers, sellers, and renters. Both aggregate MLS listing data, provide property value estimates, and connect consumers with agents — but their data sources, estimate methodologies, and product strategies differ in ways that affect which platform is more accurate and useful for any given search.
Realtor.com: Owned by News Corp and operated by Move, Inc., Realtor.com has a fundamental data advantage: it maintains an official partnership with the National Association of Realtors (NAR) and receives MLS data feeds from approximately 800 MLSs nationwide, typically faster and more completely than competitors. This means active listing data on Realtor.com is more likely to be up-to-date — critical in fast-moving markets where a home can go under contract within hours. Realtor.com's property estimate (called "Realtor.com Estimate") uses public records and recent comparable sales. Realtor.com's 2026 features include enhanced school district data, walkability scores, commute time calculators, and a renovated mobile app with improved search filters. Traffic: approximately 70 million monthly unique visitors, placing it second behind Zillow in consumer mindshare but ahead in MLS feed completeness.
Zillow: With approximately 230 million monthly unique visitors, Zillow is the most-visited real estate platform in the US by a wide margin. Zillow's Zestimate — its automated home value estimate — is the most well-known AVM (automated valuation model) in real estate, with a national median error rate of approximately 2.4% for on-market homes and 7.7% for off-market homes. Zillow has invested heavily in improving Zestimate accuracy using machine learning trained on decades of transaction data. Zillow's product suite has expanded: Zillow Showcase listings feature interactive floor plans and virtual tours; Zillow Home Loans offers mortgage pre-approval; and Zillow's Premier Agent program connects buyers with local agents who pay for lead generation placement. Zillow exited iBuying (Zillow Offers) in 2021 after significant losses, refocusing on the lead generation marketplace model.

Data quality: A persistent critique of Zillow is that listing status updates can lag MLS data, meaning some "for sale" listings on Zillow may already be under contract. Realtor.com's MLS partnership means its active vs. pending status is generally more current. For off-market research and home value estimates, both are directional tools — neither Zestimate nor Realtor.com Estimate should replace a comparative market analysis (CMA) from a local agent.
The 2026 recommendation: Use Zillow for broad market research, Zestimate price context, and neighborhood discovery — its UI and mobile app are slightly more consumer-friendly and its traffic ensures the most agent reviews and listing photos. Use Realtor.com for active listing accuracy in hot markets where status freshness matters, and for MLS data reliability on recent days-on-market counts. Serious buyers should use both alongside direct agent access to MLS data.
