Redfin vs Zillow Comps - Who's More Accurate and REI Friendly?

[Zev Dobuler]

Sometimes when running comps against “Sold” properties, I see that one site has more “Sold” properties than the other. I can understand why one would have a listing that the other one doesn’t but why would there be a discrepancy in the “Sold” properties? Zillow just showed me a few sold properties in a certain zip code that Redfin didn’t show. Does one website update faster than the other? Which website would you recommend using to check comps and what are the overall differences between the sites that an investor should know about.

Thanks for your help!
