Frequently Asked Questions
No online estimator is perfectly accurate. Redfin Estimate and Zillow Zestimate are the most well-known, with median error rates of 5-7%. For 2026, Redfin claims slightly better accuracy due to MLS data access. However, a professional CMA from a local agent remains the gold standard for accuracy.
Each platform uses different data sources, algorithms, and update frequencies. Zillow uses public records and user submissions, Redfin incorporates MLS data, and others use various combinations. Recent renovations, unique features, and local market nuances also cause discrepancies.
EstatePass is the best for agents because it creates branded landing pages that capture leads directly. Other tools like Zillow and Redfin capture leads for their own networks. With EstatePass, homeowners visit your branded page, enter their info, and become your lead.
Most use Automated Valuation Models (AVMs) that analyze public records, tax assessments, recent comparable sales, and market trends. Machine learning algorithms weight these factors based on the property type and location. Some also incorporate MLS data and user-submitted information.
Use Zestimates as a starting point, not a definitive value. Zillow reports a median error rate of about 6.9% for off-market homes and 2.4% for on-market homes. For a $400,000 home, that means the actual value could be $27,600 higher or lower. Always supplement with a professional CMA.
Create a branded home value page (like EstatePass offers) and share it in your marketing: social media ads, email campaigns, door hangers, and direct mail. Homeowners request estimates, giving you their contact info. Follow up with a professional CMA to convert them into listing clients.
Update frequency varies: Zillow updates Zestimates weekly, Redfin updates daily for on-market homes, and Realtor.com updates when new MLS data arrives. During fast-moving markets, all online estimates tend to lag behind actual values by weeks or months.
An online estimate uses algorithms and public data for a quick approximation. A professional appraisal involves a licensed appraiser physically inspecting the property and considering condition, upgrades, and unique features. Appraisals are required for mortgage lending and cost $300-$600.
