The Verdict
CoStar is built for commercial brokers and property investors, with a focus on property-data and market-analytics. Redfin targets home buyers and home sellers and leads with property-search and home-valuations.
CoStar uses custom enterprise pricing, while Redfin starts at $1.5/mo — a tangible advantage for teams with a fixed budget.
Redfin has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. CoStar requires a paid subscription from day one.
