About
The Redfin Estimate is Redfin's proprietary automated valuation model (AVM) that provides instant, data-driven estimates of a home's current market value. Unlike many competing tools, Redfin has direct, complete access to Multiple Listing Service (MLS) databases — the same data sources real estate agents rely on — giving it a significant accuracy advantage. The underlying algorithm analyzes hundreds of data points, including recent comparable sales, neighborhood trends, property-specific attributes (e.g., water views, busy street proximity), and broader market conditions. This powers a median error rate of just 1.95% for on-market homes and 7.49% for off-market homes — making it a highly reliable starting point for pricing decisions. Estimates are refreshed daily for active listings and weekly for off-market properties, ensuring the data stays current with shifting market conditions. The tool is completely free to use and is embedded throughout Redfin's platform, including its mobile apps. For homeowners or sellers who want to go beyond the automated estimate, Redfin also offers free consultations with local Redfin Agents who can provide a professional, in-person valuation that accounts for recent renovations and unique home characteristics not always captured in MLS records. The Redfin Estimate is best used as an informed starting point for pricing strategy, portfolio tracking, or purchase research — not as a replacement for a licensed appraisal.

Pros
- Highly Accurate for On-Market Homes: With a 1.95% median error rate on active listings, the estimate is reliable enough to inform serious pricing and purchasing decisions.
- Completely Free to Use: No subscription or sign-up required to view estimates, making it accessible for any homeowner, buyer, or investor.
- Backed by Real MLS Data: Direct access to MLS records means estimates reflect actual, agent-listed sale prices rather than filtered public-record data.
- Regularly Updated: Daily refreshes for on-market homes ensure estimates stay current in fast-moving markets.
Cons
- Lower Accuracy for Off-Market Homes: The median error rate rises to 7.49% for off-market properties due to reduced data availability, which may be too imprecise for high-stakes decisions.
- Not a Formal Appraisal: The estimate cannot replace a licensed appraiser's report and should not be used for mortgage, legal, or insurance purposes.
- US-Only Coverage: The Redfin Estimate is limited to US residential properties and is not available in all markets with equal accuracy.
